2024 Chevrolet Colorado

The turn signal system intermittently malfunctions. When using the turn signal, the auto-cancel function sometimes activates the opposite signal, and at times the stalk does not stay engaged when attempting to signal. This creates a safety risk because surrounding drivers may receive the wrong turning/lane-change indication or no indication at all. The issue has occurred intermittently while driving and has been presented to Cox Chevrolet in Bradenton, Florida multiple times. Cox Chevrolet has verified turn-signal over-cancel and performed prior repairs/programming. However, the issue has not been entirely resolved and continues to occur intermittently. No crash or injury has occurred, but the condition creates a risk of collision during turns, merges, and lane changes

Incident Jun 3, 2026

Vehicle intermittently lunges forward during the 2nd-to-1st downshift, even while the brakes are being applied. When this occurs, the vehicle unexpectedly accelerates or surges forward slightly, travels farther than anticipated, and feels similar to being bumped from behind. Because the condition occurs at low speeds, often in tight areas such as parking spaces, stop-and-go traffic, or before a crosswalk, it creates a risk of collision with pedestrians, vehicles, or objects. The issue has been reported to Cox Chevrolet in Bradenton, Florida multiple times, but continues to happen.

Incident Jun 3, 2026

My dog and I were headed to Home Depot on [XXX] when without any warning there was a very loud boom. My first thought was that we had been shot at. Once I gathered myself I realized the sunnroof glass had exploded. I rarely open the sunroof but do on occasion have the shade open, luckily it wasn’t open or my dog and I would have been sprayed with the glass which could have caused serious eye injury and potentially a crash. I’ve had 2 Chevy dealers tell me that is not a warranty issue that it was likely caused by a rock being thrown up. I do not believe this was the case. The closest vehicle was some 500 feet in front of us. Because it was such a violent explosion I believe it was a pressure explosion. I am also very surprised that the glass is tempered and not laminated. I have insurance so I’m not concerned with getting it repaired. I just want you to know I think it a very serious issue.

Incident May 28, 2026

The contact owns a 2024 Chevrolet Colorado. The contact stated that while driving on several occasions at various speeds, and the brake pedal was depressed the pedal remained floored. The contact stated that the vehicle eventually slowed down on its own and came to a complete stop. The was towed to a dealer where it was diagnosed that the master cylinder needed to be replaced. The vehicle was repaired but the failure reoccurred a little over a month later. The vehicle was towed back to the same dealer where it was diagnosed that the battery was dead and the battery needed to be replaced. The vehicle was repaired but the failure reoccurred approximately 17 days later. The vehicle was taken to the same dealer where it was diagnosed that the drivers door wire harness needed to be replaced due to an electrical issue that killed the battery. The vehicle was repaired but the failure reoccurred approximately four months later. The vehicle was towed to the same dealer where the vehicle has yet to be diagnosed as of yet. The manufacturer notified of the failure. The failure mileage was approximately 8,400.

Incident Nov 7, 2025

Check engine light came on and the dealership said it was because the coolant was low due to the radiator hose leaking. I was told by the actual mechanic that they’ve had to do a lot of radiator hoses and that it is a known defect with the Colorados and the traverses but that GM hasn’t done a recall on them yet. That is what brings me here. My truck is only 2 years old and this shouldn’t be happening right now. Thank you for taking the time to review this and I hope GM addresses the matter promptly.

Incident May 14, 2026

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 35k miles). You can check the Colorado Chevy forum, youtube, etc., et al, and find plenty of instances where this has failed. As this is the cooling system, it can cause the engine to overheat and potentially ruin the engine. The flaw seems to be an engineering issue with the rubber seal they use (instead of a high quality o-ring) to seal the upper hose to the radiator. Additionally, since this can cause engine failure it should be addressed immediately. Instead, my local Chevy dealer, since its not a recall item, said they could schedule a time next week for me to LEAVE the truck and then they would get to it in 7-10 days. This is extremely unfair to the consumer who depends on these vehicles. This should absolutely be a recall item. You can find 1000's of examples online and if you can pull GM repair data, I'm sure you'll find 1000's more.

Incident May 6, 2026

Truck has 36,669 miles check engine light came on and was idling loud, after being looked at my a Chevrolet dealership came back a faulty radiator hose, and coolant was leaking. Too new of truck for this kind of problem

Incident May 1, 2026

Coolant leaking from the upper radiator inlet hose connection. The Malfunction Indicator Lamp (MIL) illuminated in the Driver Information Center (DIC).

Incident Mar 20, 2026

The vehicle is registered to me; my mother was the driver at the time of the failure. At ~2,963 miles, the truck developed intermittent check engine and ABS warning lights. The dealer pulled DTC C058A (brake system control module) and P25A2. Per GM bulletin PIT6012A, the battery was replaced and a brake plunger motor sensor learn was performed. The same codes returned within weeks. The dealer then diagnosed internal failure of the brake master cylinder and reservoir, documented the vehicle as "unsafe to drive," and replaced both under warranty. The truck sat at the dealer over six weeks due to a nationwide parts backorder. Repairs were completed April 4, 2025. On May 2, 2025, at ~6,500 miles, the driver was traveling downhill on a city street in the rain at roughly 20 mph. The brake pedal suddenly became hard and resistant. Despite full-force pedal pressure, the vehicle could not be stopped. It entered an intersection, struck another vehicle, then struck a tree. Front and side airbags deployed; the vehicle was totaled. The driver sustained a concussion, broken finger, and severe back and knee injuries, was transported by ambulance, and required months of concussion treatment including vestibular therapy. The hard, resistant pedal is consistent with failure of the electronic brake boost assist (eBoost) system, leaving only unassisted hydraulic braking (roughly 4–5x normal pedal force). This matches other owner reports and the class action in Barron et al. v. GM LLC, which cites defective master cylinders with a missing internal cartridge seal on the same platform. The vehicle is no longer available for inspection. The driver was concussed with significant short-term memory loss at the scene; statements in the police report may not reflect the mechanical failure. Full police report available on request (exceeds 10 MB limit).

Incident May 2, 2025

Check engine light with codes p0700 and p2796 has been happening for months with multiple failed repair attempts. Vehicle was returned to me by the dealer supposedly fixed. I drove it 15 minutes to the high school for an art fair my daughter was in. They (my family) rode with me home. Check engine light was on again. On the way home, the transmission was acting strange, not shifting properly. About half way home, it got stuck in a gear at 3500 or so rpms and would not shift. I tried the manual shifter, and it didn’t work. Stuck in gear. Concern was that we were approaching a hill when it did this, and I could not get the vehicle to shift to deliver the appropriate level of power I needed to ascend the hill. It thankfully did eventually shift, but it was scary for a few seconds, especially since I had my wife and all three of my kids in the vehicle. I dropped the vehicle off the next morning. It got stuck in gear at 3500 RPMS again on the way to the dealership. Two dealerships have made multiple failed attempts to fix the transmission issues. Several attempts to contact GM have gone without a response. No one in my family feels safe in the vehicle after what happened.

Incident Apr 17, 2026

The backup camera view does not appear on my dash screen along with all other camera views. There were no warnings or indicators. It was working the last time the vehicle was driven and then failed on the next vehicle start up.

Incident Apr 19, 2026

The contact owns a 2024 Chevrolet Colorado. The contact stated that while operating the vehicle, there was a grinding sound coming from the front of the vehicle while turning in either direction. Upon inspection, the contact discovered that the front driver's side wheel well plastic cover was unsecured and had fallen and was rubbing on the front driver’s side tire while turning. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The contact stated that there was a rattling sound coming from the vehicle. Upon inspection, the contact discovered that the driver’s- and passenger-side step rail bolts were missing or loose, leaving the step rails unsecured. The contact replaced the bolts. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 10,000.

Incident Oct 1, 2025

I have had my vehicle for less than 2 years and less than 25,000. I had it in for regular maintenance and was told I had no coolant. After a pressure test the dealership told me I had a large crack in the coolant line. It will 2 weeks to get the part and I can’t drive my truck. This needs to be made a recall and the part needs to be made available asap.This could of caused serious damage to my engine and could of cause me to have an accident.

Incident Apr 16, 2026

The contact owns a 2024 Chevrolet Colorado. The contact stated that while attempting to activate the right turn signal, the left turn signal was displayed. No warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed with an overcorrection and overcancellation of the signals. The vehicle was not repaired. The manufacturer was contacted, and the failure was confirmed, but no assistance was provided. The failure mileage was approximately 8,000. The VIN was not available.

Incident Nov 1, 2025

About two weeks ago my truck popped up a message asking if I had installed new brake pads. When I selected no, on my Home Screen, where I can see the systems of my truck the front bake wear indicator no longer showed a percentage. When I inspected my brake pads the front outer pads still had a good amount of pad left, but when I checked the inner pads they had been severely worn down compared to the outers. On 4/1 I brought my truck to a Chevy dealership to have them diagnose why there is such uneven brake pad wear. After they inspected the brakes the dealership then told me that due to the brake pad clips being installed improperly my pads were wearing out unevenly. The dealership also showed me a service bulletin (25-NA-365) that GM had put out for trucks in the 2023-2026 models that stated due to a factory installation defect on the clip that holds the brake pads in place it is causing uneven wear on the brake pads. I told the dealership that the clip causing uneven wear on the brake pads could become a safety concern if owners don’t know about this because the braking effectiveness of the truck is wearing out faster than what the owner is told by the sensor. I told them in extreme cases that if the pad completely wears out then the rotor could be damaged and cause a very significant impact to the safety of the vehicle because the braking system will be severely degraded. I was told that since it is just a service bulletin the dealership and GM do not have to cover the repairs of the brake pads because a service bulletin is not the same as a recall and that brake pad wear is a normal maintenance item. My concern is that trucks with similar mileages as mine of 20000 miles are wearing their brake pads out at an alarming rate and the dealership and GM are not taking the responsibility to ensure that the issue is resolved and new pads are replaced to ensure proper braking effectiveness on the roads.

Incident Apr 1, 2026

Mid December 2025 my forward collision warning, adaptive cruise control, automatic emergency braking and auto high beams all stopped working. I combined the repair request with my next oil change Dec 22, 2025. The Chevy dealer, Serra, advised me that Chevrolet had no way to correct these problems, one of which was a $950 option. I have returned to the dealer more times, still no fix. I have talked to Chevrolet customer service, asked for a buy back, or car to drive till repairs and was denied. Chevrolet simply says just wait till we figure out how to fix our broken truck. I feel Serra Chevrolet has done all they can and has otherwise provided me with excellent service. Since the problems include safety features and I have waited over 4 months to date, I hope your agency can expedite the repair and secure some type of compensation for me.

Incident Nov 15, 2025

2024 Chevrolet Colorado with intermittent safety defect at highway speeds. Vehicle displays P215B along with Service ESC, Service Traction Control, and Reduced Acceleration. Speedometer becomes erratic and the vehicle loses reliable speed signal at highway speed. Dealer kept vehicle for 15 days, stated repairs were made, but the same issue returned within about 2 miles of pickup on the highway. Vehicle was returned to dealer immediately. As of April 2, total days out of service will be 21. I do not believe the vehicle is safe to drive or safe to transport my family in. GM case has been opened. This is an ongoing safety issue involving loss of speed signal and reduced acceleration during highway operation.

Incident Dec 3, 2025

Coolant leaking from the upper radiator inlet hose connection

Incident Mar 23, 2026

I have a 2024 Chevy Colorado Trail Boss that needs an Upper Radiator Coolant Hose. But apparently this is on nationwide backorder because although there is not a recall GM put a bulletin out they are aware of the issue that appears to be a degraded seal inside hose fitting so the whole hose needs replacing. I live in [XXX] and it is not available here and I have called OH, [XXX] , [XXX] and other state dealerships and Noone will sell that part because of the backorder. My truck has 40k miles. And every dealer I called this is a huge issue with these trucks. So it is not a wear issue when it is on nationwide backorder and it'll take 1-2 weeks +/- to get. My warranty won't cover as they say it is a wear part and no recall. So how can there be no recall on a nationwide issue with these trucks. My truck cant be driven right now due to check engine light, low coolant, leaking hose, fan blowing high, no heat and this is all related to this backordered part. Someone told me to report this issue so that is what I am doing now. Again this should be an active recall. Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident Mar 21, 2026

When coming to a stop the vehicle slams into 1st gear raising the RPMs and pushing the vehicle forward even when the brakes are being applied. No warning lights no other malfunction or symptoms. Has occurred this I first purchased the vehicle new in January of 2025. Has almost caused collisions. Never took it to the dealership due to the information I've gathered if was a common issue but I believe it is a major safety concern due to the vehicle lunging forward when the brakes are applied.

Incident Mar 22, 2026

My truck only has 16,600 miles on it and the rotors and brakes are already shuddering. The dealership told me I needed my front and rear brakes and rotors replaced. It is beyond ridiculous when my last truck a 2020 Chevy Colorado had no rotor or brake problems and have 90,000 miles when I traded it in.

Incident Mar 10, 2026

At 20,300 miles, severe chassis and steering wheel vibration occurred during high-speed highway descents while braking. Safety risk: reduced steering control at highway speed. The vehicle was inspected by a franchised Chevrolet dealer in Lakewood, CO. The technician's written service notes document rear rotor Lateral Runout (LRO) of 0.006 inches against GM's maximum allowable specification of 0.002 inches per GM Service Bulletin 00-05-22-002 — 3x the engineering limit. The defect was confirmed in dealer documentation and is available for inspection. After I identified this discrepancy, the Service Manager claimed the technician meant 0.006 mm (metric). Photographic evidence from the dealer's own diagnostic video shows a dial indicator clearly labeled in 0.001-inch increments with the needle resting on the 6th tick mark. A metric reading of 0.0002 inches is physically impossible to display as 6 full divisions on this tool. GM Customer Assistance denied the warranty claim, classifying it as maintenance. Lateral Runout is a geometric specification, not a wear measurement. A rotor 3x out of tolerance at 20,300 miles is a material or assembly defect. No warning lamps appeared. The safety concern remains unresolved.

Incident Feb 23, 2026

The contact owns a 2024 Chevrolet Colorado. The contact stated that while driving at an undisclosed speed, the brake pedal depressed to the floorboard and was spongy. Additionally, the navigation system shut off unexpectedly, and the Forward Collision Avoidance warning light illuminated, causing the seat belt to tighten while the vehicle was in park. The contact also received OnStar alerts that the vehicle was being stolen and that the 12-Volt battery voltage had dropped. The manufacturer was not notified of the failure. The vehicle was driven to the dealer to repair the issues, but the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 8,285.

Incident Jun 1, 2024

A few weeks ago the heat started performing intermittently, about half the time only blowing out cold air even with the temperature set to 85. I live in Minnesota and we have had numerous weeks of below 0 temperatures. Lo and behold, I find out there are widespread reports of the O ring seals on the radiator and heater hoses failing and causing coolant leaks. These leaks are significant enough to render the vehicle inoperable and with no cabin heating or cooling. This could lead to life-threatening situations in adverse weather conditions. It could also create dangerous roadside failure situation in heavy traffic, particularly on interstate highways. Dealers are aware of the issue and are currently repairing vehicles under warranty. However some dealers are telling owners that the cooling system is not part of the engine and drivetrain, and therefore is not covered under the original factory warranty if the vehicle has exceeded the initial bumper to bumper warranty limits. Dealers are also telling owners that parts are on backorder due to high demand, and that repair wait times could take weeks. The vehicle is unsafe to operate with a known coolant leak.

Incident Feb 11, 2026

Upper radiator hose leak with 36,750 miles(just out of warranty) 3 days after it was at dealer for oil change and replacing the heat shield. Apparently VERY common in these vehicles which says they are aware but haven't FIXED the issue, should be a RECALL!!

Incident Feb 27, 2026

Incident Mar 1, 2026

The contact owns a 2024 Chevrolet Colorado. The contact stated that the roof of the vehicle had several dents. The contact became aware that several similar vehicles had the same dents to the roof. The contact referenced NHTSA ID Number: 11014388 (STRUCTURE) as the cause for the failure; however, the VIN was not included. The dealer was notified of the issue. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 72,000.

Incident Feb 23, 2026

Check engine light appeared and fans kicked on loudly. Stayed on even after shutting the vehicle off. Vehicle is a 2024 with only 28,639 miles on it. Upper radiator hose was leaking and would not seal. Took to dealership for repair and replacement. Was informed it was the 3rd Chevy Colorado this week with this issue! Was stunned. Further internet research found a staggering number of forum posts with this same issue. This is a recall-worthy issue at this point. Please consider issuing a recall based on the safety issues this may pose if engines seize or overheat as well as the sheer number of the same reported incidents.

Incident Feb 10, 2026

upper radiator fitting is leaking, Chevy is replacing the radiator and the hose

Incident Feb 3, 2026

The truck has 28,000 miles and has been only driven for commuting on interstate conditions. While traveling on an 80 mile commute, I experienced complete engine failure while traveling at 75 MPH (the posted speed limit is 80). As the engine failed, I was placed in a dangerous position as there is no pull-off and traffic was heavy. I was stranded in winter conditions with no ability to heat or stay warm. OnStar assisted with a tow to the closest dealership which was Ressler Chevy in Bozeman, MT. The results of the inspection indicated a failed crank shaft, hole from internal debris in the engine block, and the engine seized. This has resulted in a engine replacement. When asked, this has been an ongoing problem with the 2.7 engine yet there is no recall and the fix is to replace it with another 2.7 with no fix to the issues. This truck has received all required maintenance through Chevy dealerships and has no upgrades or changes from the manufacturer settings when purchased a year ago. There were no signs, symptoms, or warmings prior to the engine failure.

Incident Jan 29, 2026

Radiator hose failed in under 1.5 Years on 2024 Chevy Colorado. Parts are back ordered for months, this is clearly a manufacture defect that could lead to overheating the engine and engine damage and failure

Incident Feb 11, 2026

Not sure if this is your typical safety issue. Voice activation button @ RH side of steering wheel failed approx. one month after vehicle purchase. This button allows one to call out, use GPS, vehicle functions, radio, etc "handsfree". Message @ infotainment screen stated "click here to purchase subscription" which I was not made aware of by anyone involved w/ sale. Cell phone will link up w/ vehicle manually for sending or receiving calls, but requires holding phone to start or end them (and pick who you want to call)...which is illegal in California and unsafe. Inquiring w/ Onstar led to having to pay for monthly subcription to "reenable" functionality. Seeing as this IS a safety item, I wonder why I would be required to pay a monthly 45.00 fee for it to function. Had a 2015 Ford that worked perfectly...for free

Incident Apr 25, 2025

See attached document for complaint.

Incident Nov 1, 2025

Even when new, the truck would abruptly down shift from 2nd to 1st, every now and then. Then with about 3000 miles on the truck its started doing every time, once the transmission is warmed up. It seemed to get better and then started again with about 4000 miles and kept getting worse. It got so bad that the truck would shudder and it almost felt like I was getting rear ended and you could hear knocking from the transmission. I then turned it in the dealer and when I got it back, the dealer stated that they had to replace a valve in the valve body.

Incident Sep 18, 2025

Right turn signal auto cancel activates the left lane change signal resulting in oncoming traffic assuming a left turn to be performed but this vehicle continues straight resulting in a collision hazard. This has been happening since the purchase of the vehicle 2.5 years ago but dealer is unwilling to fix.

Incident Jan 13, 2026

problem since day 1. Instrument cluster goes dark frequently. no speedometer or gauges are illuminated. may stay dark for long periods of time and other times it is shorter periods. sometimes smacking it will bring it back up. sometimes not. cluster changed 2 times by dealer. problem continues. code read problem with harness connector showed up once but they cleared it and it hasn't come back. panel went dark 12 times the other day in 30 miles. dealer is now ignoring it! 80 year old man driving at night with no instrumentation is a serious hazard and POTENTIAL lawsuit!!

Incident Oct 4, 2024

The front brake pads are showing extremely uneven ware. Outer brake pad is at 2mm and the inner is at 7mm due to a spring issue on the front caliper. There is also a lip on the left rotor. The tech used 25-NA-365 to help identify the issue. However, my VIN is not covered under this repair. The result is a $500 out of pocket repair for something that should be a mfg defect and not wear and tear. As this was already outlined as an issue with other 2024 Chevy Colorado's I am asking this to be expanded to cover my vehicle as well. The issues was also causing my brake sensors to "detect" new brakes and I had to inform the vehicle that I have not had brake service done to trigger this alert.

Incident Dec 22, 2025

Starting on [XXX] while driving the truck, the gauge cluster and radio went completely out (black screen) and the five red automatic emergency braking LED's illuminated and stayed on for up to 5 minutes. This happened about 8 times on my commute home. This happed again on [XXX] after the dealership did a software update to resolve the issue. The truck was serviced again on 09/11/2025 and I was told that GM has no software fix for this at this time. On 09/25/2025 again the truck was serviced again to try and fix the issue. This time the radio came on and I could not turn it off or adjust the volume. I went straight to the dealer and showed the issue to the service manager James Mask. The cluster and radio to this day continue to go out (black screen), no speedometer, gauges of any sort for a period of time from 15 seconds to 30 minutes. This leaves me with no way of obeying the speed limit, fuel level, oil or temperature gauges. GM is being blasé about this. They have admitted they know the issue exists but can't or won't offer a fix for the issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
