Incident Jan 29, 2026

Transmission will not go into drive or reverse. This also happens when car is in drive going down the road it will all of a sudden lose power and not go when pressing gas pedal. Vehicle has to completely shut off several times before it will go back into gear. No warning before it started. This can be dangerous when it happens in traffic and I can’t move car out of the road. It has not been inspected yet. Also blind spot warning does not always says it needs serviced.

Incident Nov 22, 2025

I've taken this SUV to the Chevy dealership 4 times now for the same issue. SUV will not start at times then starts, it will even turn off on the road without warning. New Battery and Chevy can not find out issues $500.00 later. The brake pedal becomes hard to push down, and it will not start: wait 10 mins or so and it will start. Even the remote start at times will not work. Chevy has had it for 30 days at a time and I'm being told to bring it back when it happens, how do I that!

Incident Dec 15, 2025

Transmission has to be replaced due to transmission slipping and delayed shifting under heat and prolonged highway driving. This issue also causes SUDDEN hard shifting, hard breaking, shaking of the steering wheel, along with grinding of gears!! This is a safety issue to to no warning signs at all along with a sudden drop in speed and power!! While driving on the interstate or highway this sudden change can cause the vehicles behind you to rear end you or cause a pile up!!! The driver has no control of vehicle when these issues happen!! A loss in control due to shaking of the steering wheel is a huge issue!!! Lack of shifting or hard shifting causes a SUDDEN stop of vehicle with no warning signs while driving!! It is going to cause a crash!!!! These are serious and dangerous issues that Gm will NOT do a recall for!! GM is aware of the issues due to Suburban, Tahoe and Silverado vehicles in the year models 2018-2023 having this reoccurring issue!!! I recall needs to be done to save someone’s life!!!!! I have only had my suburban for 8 months!! I was not made aware of this issue at all!!!!!! This also causes rough idle!!!!!!!!

Incident Sep 17, 2025

Wheels 22" Chrome upgrade from the standard wheels from the factory The tire bead where the chrome meets the interior alloy metal corrodes. Thetires start losing air pressure. The tires should be 35 PSI. The front tire dropped to 23 PSI making sterring pull to the right. This is a problem with all 4 tires on the 2018 Chev Suburban Premier. I need to check tire pressure weekly

Incident Oct 6, 2025

No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. Before this going uphill is extremely sluggish, where I have the gas peddle almost to the floor, but nothing happens other than decrease in speed until it finally, about 30 seconds-1 minute, where it kicks into overdrive. Even then, speed does not increase by more than 5-10 mph depending on the incline. I have not brought it to get looked at yet, as I've seen these issues have been reported by numerous consumers without any recalls being sent out other than the breaking system update.

Incident Jul 1, 2025

My vehicle completely shuts off while driving. All of the components on the dash and even my steering wheel moves into the prestarted vehicle position. It has happened 3 times in the past week now. One particular instance, I was on the highway and thankfully it came back on immediately before completely stopping but shutting off while driving 65mph is so dangerous.

Incident Aug 22, 2025

Dear NHTSA, I am submitting this complaint to report a recurring and potentially dangerous issue with the transmission in my 2018 Chevrolet Suburban, which I purchased brand new in 2018. At approximately 60,000 miles, I experienced severe transmission issues that led to a complete transmission replacement. Now, at around 133,000 miles, I am encountering the same symptoms once again. The transmission makes a loud clunking noise during acceleration and braking, and shifts gears abruptly and harshly. These symptoms appeared suddenly, with no warning lights or prior alerts. This problem poses a significant safety concern. The vehicle sometimes struggles to accelerate properly, making it dangerous to merge into traffic. Additionally, the forceful shifting makes the vehicle feel unstable and unpredictable, as though something beneath the car might fail while in motion. I transport my husband and our children in this vehicle, and this issue puts all of us at serious risk. I have scheduled another appointment with a GM dealership to inspect the vehicle. However, given that this is a recurring failure involving a critical system, I am requesting that NHTSA investigate this matter as a potential defect affecting other owners of the same model. Thank you for your attention to this serious concern.

Incident Jun 22, 2025

My Suburban is having the same issues as the most recent recall on the 2021-2025 Chevrolets. The issue is with pretty much all of the motors that go from the V8 to the 4 cylinders. It's doing the same exact thing a friend of mine's 2019 Tahoe did. It's making a loud knocking/ticking noise. When you first get to going it starts almost sputtering which can cause issues if you're in oncoming traffic trying to cross roads.

Incident Dec 1, 2024

The Infotainment center display is black and therefore unable to utilize backup camera. The screen is still sensitive to touch but does not display anything for any function. Primarily a safety risk for backing up a large vehicle.

LIFTER ISSUES AFTER 60000 MILES HAD TO REPLACE ALL AROUND 5000 DOLLARS

Incident Apr 17, 2025

Currently own a 2018 Chevy Suburban with a lifter issue in the engine. This is a known issue with Chevy as many vehicles have experienced this problem from zero to over 100k miles. Chevy has not issued any help or support with customers with this issue. My vehicle is well maintained I get oil changes frequently and have never not done a required service when needed. When I notice an issue I immediately take it to in Regal Chevy for repairs and no matter what the issue is I get it repaired on the spot. I find it odd that this is a recurring issue and Chevy has done nothing to help support loyal customers.

Incident Dec 2, 2024

The 2nd row of the vehicle has 2 captain chairs and both seatbelt retractors failed.

Incident Oct 7, 2024

Rim corrosion resulting in loss of air pressure. The inner portion of the rim is corroding causing the tires to loose pressure. Depending on the amount of corrosion this could lead to a catastrophic failure at some point due to sudden loss of pressure. I took my vehicle to a tire shop thinking there was a puncture causing it to loose pressure. The manager explained to me that the pressure loss was due to corrosion of the alloy rim and that it is common with Chevrolet vehicles with factory alloy rims. The only solution to the problem is to have the rims possibly refurbished or replaced.

Incident Nov 3, 2023

Car abruptly lost power while driving causing rapid deceleration and requiring immediate action to steer vehicle off the active roadway without hitting other vehicles or causing property damage. There were no warning lights or signs until this occured. The vehicle was later towed to chevrolet who informed us that this was a KNOWN ISSUE these cars have where their "lifters fail and sometimes even damage the camshafts" If this was a known issue why would it not have been addressed in a recall. After speaking with the dealer I searched the internet for the same issue and it is widespread across several GM cars including mine. GM now wants $3,100 to repair a dangerous manufacturer defect.

Incident Oct 4, 2023

While slowing down to make a left hand turn at an intersection, my vehicle suddenly lost power steering and the entire system completely shut down. There was no electronic function during that time. I had to put the vehicle in park, turn the key to the off position and then start it back up. It has happened multiple times, both at low speeds in drive and reverse. This would have caused a collision if there was oncoming traffic at the intersection at that time.

On two occasions, most recently on 6/13/23 the vehicle went from 70 mph to 10 mph very suddenly on an Interstate in heavy traffic--very dangerous. The display indicates an over-heated transmission but the dealer believes its some electrical problem. This 2018 Suburban has an 8 speed auto transmission which has a lot of on line complaints and lawsuit pending.

Incident Jun 13, 2023

While driving the vehicle lost all power and after about 20 seconds power came back on. The repair was the battery cables which was apparently very common on the make and model of vehicle. It's unsafe and can cause an accident and apparently happens on the majority of vehicles same year and make.

Incident Mar 25, 2023

Vehicle starts dinging with warning - Service Trailer Brake System - and warning - Action Required Steering Assist is Reduced Drive with Care - ABS Light - Traction Control. Power steering goes out and assumedly ABS and Traction Control stop working.

My rear left tire locks when I’m doing sharp turns and I don’t see any traction control lights come on when that happens

Incident Mar 3, 2023

The second row - driver's side seat belt no longer was retracting, making the seat unsafe. This belt had been slow to retract since we purchased this vehicle from the dealership in June 2022, but it stopped retracting in mid January 2023. As my extended warranty only covers drive chain, the dealer charged me $627.43 for parts and labor to replace the seat belt. It is disappointing that Chevrolet does not warranty the basic safety equipment for the life of the vehicle.

Incident Jan 23, 2023

STARTED ABOUT 3 WEEKS AGO, DRIVER AIRBAG WARNING LIGHT APPEARED ON DASH. RESET IT AND ALERT STAYED OFF FOR A WHILE AND THEN STAYED ON CONSTANTLY. TOOK VEHICLE TO BE REPAIRED, AWAITING PARTS.

Trailer Brake system Service Message Took it to the dealer service department and was told that a diagnostic would be needed to find problem $225, if the wiring harness is indeed defective it would be over $500 in parts and $600 in labor. A picture of the light coming on while driving was produced to the dealer service department. It first appear when driving on the freeway and we have never towed anything with this vehicle. Upon further online research we found out that this is a common and serious problem with GMC and Chevy vehicles like the Canyon, Sierra, Silverado, Yukon, Tahoe, Suburban, Colorado from years 2015-2020.

Incident Nov 10, 2022

Vehicle started shaking while accelerating. Independent mechanic and his recommended transmission shop diagnosed an issue with the transmission - specifically the torque converter. Shop said the car was unsafe to drive while waiting for new transmission as it could lose ability to accelerate while driving. When I asked the transmission shop if they felt the previous owner(s) may have abused the car with their driving to cause the issue at a relatively low mileage, they said this was a systemic issue with this vehicle. In fact one of the repair techs had the exact same issue with his personal vehicle at similar mileage (same make / model).

Incident Dec 12, 2022

On approximately December 23, 2022, I notice that the UV protection coating on the hood and roof of my SUV is no longer protecting these areas of my vehicle. Which I am now concerned could lead to rusting on my 2018 SUV. I reported this issue after seeing many complaints on the WEB for the same problem by vehicle owners. A Chevrolet dealer mechanic also informed me of customers voicing my concern about the UV-protecting coating issue. I'm worried this issue will continue and affect the painting of my entire vehicle.
