2021 Chevrolet Traverse

Alternator fail before 60,000 miles. Had the car almost 3 years and children in it. Apparently a known common issue yet no recall it’s not a reliable car

Incident May 6, 2026

While driving, the steering wheel became very hard to control. A system warning came up on the dashboard screen stating that the steering wheel was not working. With an 18-wheeler coming up behind me the decision to pull over was made. The left hand turn into an auto part store was made with much difficulty and so was trying to park. Gentleman inside inspected the vehicle and highly recommended NOT driving the vehicle since it was a safety issue not only for myself but others as well.

Incident Apr 29, 2026

The car sometimes will not accelerate in the 25-35 mph range and will begin to shudder and shake. This can be very dangerous when attempting to merge on a highway. This also happens when completely stopped and and then accelerating. It will shake and shudders until or not accelerate at all forcing you to take your foot off the gas and reapplying pressure slowly or slower than what should be. This shuddering can also happen at higher speeds as well. This will likely cause an accident at some point if this continues.

Incident Nov 1, 2024

What component or system failed or malfunctioned, and is it available for inspection upon request? My wife and daughter were both involved in a car accident. My wife was driving the speed limit (30-35 mph) when a car traveling in the opposite direction turned left into her lane, cutting her off, and causing a collision of the two vehicles. The front driver side of the Traverse contacted the other driver's passenger side. Upon collision, none of the airbags deployed. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? My wife hit her face on the steering wheel and suffered a fractured nose, excessive bleeding, and head/neck pain. My daughter has bruising on her legs. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Police and paramedics responded to the scene and a police report was generated. My insurance company is currently assessing the damage, and the vehicle is being held in a lot. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

Incident Apr 13, 2026

Rear camera failed; worked intermittently then failed completely. Dealer took two hours to supposedly diagnose it; did what they called a "reboot"; camera failed again immediately. Ordered component, 699.00, plus another two hours to install. 1,339 total to repair.

Incident Jul 1, 2023

Both exhaust pipes before the catalytic converter are cracked and leaking at the same welded mounting bracket. One of them GM is coving under the extended warranty but the other one also needs replaced the turn off the engine warning light. It is allowing exhaust gas to leak under the car and is preventing the emissions from operating properly.

Incident Mar 3, 2026

The contact owns a 2021 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle failed to respond intermittently upon depression of the accelerator pedal. Additionally, the contact stated that the gear shifter failed to respond or responded slowly when releasing the gear shifter button intermittently. The gear shifter was easily moved to a different gear from unintended contact. While accelerating from a complete stop, the vehicle hesitated to respond, jerked, and made an abnormal sound while the RPMs were significantly elevated. The vehicle failed to respond upon shifting to reverse(R), and the gear shifter was sticky. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where the contact was informed that there were fault codes found that were related to the transmission. An appointment was scheduled with the dealer for a diagnostic test. The vehicle was not yet diagnosed or repaired. The contact related the failure to an unknown recall. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 137,000.

Incident Nov 3, 2025

I AM HAVING A LOT OF TRANSMISSION SHUDDER ESPECALLY WHEN ACCELERATING. NOTICED THAT CONSUMER REPORTS STATED IN THEIR MAGAZINE THAT THIS HAS BEEN A BIG PROBLEM FOR AT LEAST 5 YEARS. I DON'T UNDERSTAND WHY NHTSA HAS NOT MADE CHEVROLET DO SOMETHING TO FIX THIS PROBLEM WITH THE TORQUE CONVERTER.

Incident Feb 1, 2025

I was driving 45 mph on a state route when all of a sudden my drive shaft bolt came completely out and split my drive shaft in two causing me to lose control.

The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 74,000.

Incident Nov 29, 2025

The electronic stability control (ESC) system and power steering system malfunctioned. The vehicle is available for inspection upon request. The power steering warning indicated a potential loss or reduction of steering assist, which could have made it difficult to steer and control the vehicle—especially at higher speeds or in traffic. This posed a potential safety risk to me and others on the road. Yes. The issue was confirmed by my local Chevrolet dealership. They determined that a software update was required to correct the malfunction. The vehicle was inspected and serviced by my local Chevrolet dealership. It has not been inspected by police, insurance representatives, or others. Yes. Immediately after shifting from reverse into drive while backing down a driveway (at approximately 5–10 mph), two warning messages appeared: “Service ESC” and “Service Power Steering, Drive with Care.” There were no prior warning lights or symptoms before this occurred.

Incident Nov 7, 2025

Odometer Fraud. The contact purchased a 2021 Chevrolet Traverse. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the mileage was 49,000. It was later discovered, after checking the Carfax report, that the mileage was 75,000.

Incident Oct 22, 2025

In the first 51,000 on my vehicle I have had 3 issues with the emissions system which has a negative impact on the environment and would prevent my vehicle from passing state inspection. GM covered the first 2 under warranty, but I now have a leak in my muffler which seems that it could be related to other issues involving brackets on the exhaust pipes breaking. This is widely reported by other Traverse owners yet GM has not extended the warranty to cover this.

Incident Oct 19, 2025

Right Rear upper and lower toe links broke nearly causing a serious accident when brakes were applied, vehicle pulled severely to the right causing it to swerve and narrowly missing another vehicle. The toe link failure on my vehicle which has only 29702 miles put my life and the life of my family members at risk. The vehicle was brought to our local licensed repair shop in Massapequa, NY where the prblem was diagnosed and repaired. No warning lights or symptoms occurred prior to this first incident. I researched this safety item for any recalls on this issue, however there are none currenlty on file for my vehicle but several for other Cheverolet vehicle with same toe link issue.

Incident Jul 15, 2025

Received a "Service Battery Charging System" dash warning message driving down the highway. Made it home and changed the battery but the issue persists and I can't drive the car. Reading online many complaints/problems with alternator and electrical premature failures. Car is a little more than 4 years old and has only 23,600 miles. Getting the car to the Chevy dealer tomorrow to diagnose problem and fix. If car were to stall out at highway speeds it could be very dangerous. This problem should receive further investigation by NHTSA. Shouldn't have electrical failures on cars with 23,000 miles.

Incident Oct 4, 2025

While going around 40mph I approached a stopped vehicle and tried to come to a stop. At this time my braking system failed, speeding the car up instead of slowing it down, this resulted in my car rear ending another vehicle. When the car accident occurred my steering wheel air bag came out but did not inflate. There were no warning lamps or messages at the time of the crash. Due to the laws in Mississippi it was declared I was at fault and the insurance company will not inspect or cover the damages.

Incident Sep 25, 2025

Radio went blank unable to access screen. Not sure reason. Upon start up couldn’t access any parts of radio. Couldn’t reset and issue still current as of today.

Incident Jul 24, 2025

Shift to park warning comes on every time I put my car into park. I can give the gear shift a hard tap so it can go into park and my car will turn off. I feel like after a period of tapping the great shift it will turn into a bigger problem.

Incident Sep 18, 2025

Incident Nov 7, 2024

Vehicle with less than 50000 miles has 2 broken flex pipes on the exhaust system that is going to cost me $1,932.66. This should be a warranty recall and GM should allow you to take it to a mechanic of your choice for repairs as the dealerships cannot give you a fair time frame to repair.

Incident May 7, 2025

Vehicle: 2021 Chevrolet Traverse Problem: Persistent “Shift to Park” message when vehicle is in Park I own a 2021 Chevy Traverse and have experienced repeated incidents where the dashboard displays “Shift to Park” even though the gear shifter is securely in the Park position. This prevents me from turning the vehicle off and has caused battery drain and confusion about whether the car is fully secured. This issue is clearly known by GM, as evidenced by a Technical Service Bulletin (TSB #19-NA-206 and others). It affects multiple model years and has prompted a class action lawsuit. Despite the widespread nature of this defect, GM has not issued a recall. I believe this issue presents a safety concern, particularly for drivers unaware that the car may not fully power down, and due to the potential for battery drain and immobilization. I urge NHTSA to investigate whether a recall is warranted

Incident Apr 23, 2025

Car was late shifting into gear. Taken to dealership and replaced tourque cpnverters for 3800. Car gets fluids checked 4,000 miles later transmition is shot fue to leak from gasket on transmition...

Incident Apr 21, 2025

The vehicle does not recognize when the vehicle is shifted to park. It states “shift to park” when the vehicle is already shifted to park. When this happens and the push to start button is pressed to shut the vehicle off, the vehicle will not shut off which becomes a major issue as the car continues to run and the vehicle’s battery will die since the vehicle will not fully shut off. This is a safety hazard because the vehicle can end up with a dead battery when this happens. I’ve looked this issue up online and it is a common issue that Chevy has failed to address.

Incident Apr 1, 2025

1. DRIVER SIDE EXHAUST FLEX PIPE BRAKET 2. Exhaust leak 3. Yes. It has been replicated and diagnosed. 4. No engine light. There was a rattling and increased exhaust noise. A hole in the exhaust pipe at the bracket location was found. 5. This condition seems to be a common problem with this year and make which I am now having to pay $600 to repair.

Incident Dec 1, 2024

My car came up with an alert message when I started the vehicle, "Service Battery Charging System Vehicle May Stall". I assumed using my remote start had somehow drained my battery or that the cold weather (30 degrees) was affecting my battery. I began driving hoping the battery would charge once running. Another alert came up, "Battery Saver Active". The alerts repeated again. In less than 10 miles from where I first started, I made it to a Les Schwab where I asked them to check my battery. The guy ran out and said my battery had more juice not running. They told me to take it to service repair shop close by. I began driving to the nearest shop and my car jerked/stopped/died, the steering was locked up and I lost complete control of the vehicle but luckily I was not far out of the Les Schwab parking lot and was able to coast into another parking area. I had to have my car towed to the repair shop where they told me it would cost $1,600 to replace the alternator, I luckily have a Platinum Extended Warranty and it appears to be covered. I am so thankful that I was not on a highway at the time and that I took the alert seriously and responded immediately. My 14 year old was in the car with me and it really scared her that the car jerked and stopped. The amount of time I had from receiving the alert to a dead battery was very short. This should not happen and I'm so glad that I was driving versus an up and coming driver (turns 15 next week) that would not have known what to do. I've done my research and this issue has been mentioned in several chats regarding owners experiences for Traverses' around the 30,000 mile mark, my car is at 40,000 miles and was serviced at 30,000. I'm honestly not sure I can ever trust my vehicle after this experience. Others have said that they fixed the issue only to have it happen again.

Incident Jan 22, 2025

The battery wasn't being charged which caused some problems. However, it was the alternator that was bad. Since the battery wasn't being charged and the alternator was failing, there were problems with steering and engine power which almost caused a collision at highway speeds.
