CHEVROLET Complaints

Recently my car's check engine light and the message "Service Stabilitrak" started coming up on my car, then my car started shaking while idling. I quickly took the car to my mechanic who assessed it, replaced my spark plugs, which did not solve the issue, and recommended I go to the dealership. In between these appointments my car was consistently shaking while idling and I would have difficulties accelerating especially after coming to a complete stop and often while making turns, this worsened after adding fuel to my car. The nearest Chevrolet dealership did a compression test and found that the psi in cylinder 1 was only 85, while the rest of the cylinders are 180 psi. They reported "internal engine damage causing misfire on cylinder 1" and quoted the repairs and replacement engine at $9500, almost double the value of the car if the engine was working. The codes P0300 "Engine Misfire Detected" and P0301 "Cylinder 1 Misfire Detected" were the two relevant codes in the report. However the car only has 49,860 miles on it. I see that other people have reported this issue as well and it continues to happen. Additionally, if the manufacturing issue or defect has not been rectified what are the chances of this happening again down the line with the same issue? This is a clear manufacturing defect in the engine of these cars that make them a safety hazard on the road. There is no telling when and where my engine may completely give out despite the car being low mileage and well taken care of. GM and Chevrolet should and must rectify this issue.

I was driving home from work, and dash warning sign came on and told me to start engine. I was currently driving at approximately 60 mph. When i came to blinking red Light i went to accelerate and truck was unresponsive. it would not accelerate and engine was off. I went to start engine and it just cranked with no start. I used onstar to get a tow truck. I was broken down in the middle of an intersection and had to wave traffic around me for 1hr 45 min. Finally tow truck came and took truck to local chevy dealership. Upon inspection they stated that it needs a new engine. I had the truck in the chevrolet dealership in feb 2026 to have the 6.2 recall done, they performed the full recall and said everything looks good. truck has approximately 60k miles on it. it failed a few months after inspection. They stated they have ordered a new engine and it would be approximately 4-6weeks minimum. Truck is sitting at the dealership

While driving the car the start loosing power and attempts to shut down, other time the steering wheel locks up up and im unable to turn steering wheel. The check engine light comes on and turns off. The dealer/ Car repair shop has been unable to reproduce issue and unable tell me what this issue is. No accident has resulted from this as of yet. But car has some kind of malfuctioning issue.

The contact owns a 2019 Chevrolet Traverse. The contact stated that while driving at 15-30 MPH and shifting gears, the vehicle failed to accelerate. The vehicle began to shudder at 50-60 MPH. The yellow engine warning light was illuminated. The vehicle was taken to an independent mechanic who determined the gear system needed to be replaced. The vehicle was taken to the local dealer, where it was diagnosed and determined a new gear system was needed. There was no warranty coverage. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 88,000.

The contact owns a 2024 Chevrolet Trax. The contact stated that while driving at 70 MPH with cruise control engaged. The low-pressure oil light illuminated. The driver was able to pull over. The vehicle was taken to the local dealer, who determined that it was 4 quarts low and replenished it. An oil compensation test was performed. The dealer found no issue. While driving, there was an abnormal banging sound. The "Pull over and turn off the engine" message was displayed. The driver noticed that there was smoke emerging from the engine. There was oil leaking from the vehicle. The vehicle was towed to the local dealer, where it was diagnosed as having a blown engine. A hole was located in the block due to low oil. The vehicle was not repaired due to the parts being backordered. The manufacturer was not contacted. The approximate failure mileage was 41,000.

The power steering randomly turns off. This is a known Chevrolet recall from the prior year model (2015) and it was recalled. I have just over 100k miles on my truck and I cannot have family members drive it because they are not strong enough to turn the wheel. If it went out on a turn the truck would plow right into oncoming traffic. It is not safe! The repair parts are $1000 with a total cost of closer to $4000. A person will trade it in before that happens. It is frustrating because we have a truck to pull and move things as needed, and we have to think about what we are doing and work around the steering issue.

I just received an email with this the following: NHTSA Recall ID Number :26V289, warning about front or rear wheel lockup. Per the NTHSA website, there is no recall. The email came from: [email protected]

Tahoe transmission failed with 103,000 miles… took to Chevrolet they confirmed, took to a transmission specialist they confirmed failure but they said the computer was throwing weird codes and they believe this has a factor in transmission issue. On the way home the brake system alert went off and the car would not go above 35 miles an hour … I get this is a safety feature but it was dangerous in the location this occurred ans this car was not that old and does not have high miles to justify this type of issues

On May 2nd 2026 I was driving my 2021 Tahoe high country with the 6.2 motor at 60 mph and started to slow down before my left hand turn. In the process of slowing down at about 40mph I heard a loud bang/thud noise. The car had completely shut down all motor related usage. I coasted into the shoulder on the side of the road the vehicle would not restart. I had my children and wife in the car. There were no check engine lights or any other warning signs on the dash prior to this happening. The Tahoe was running perfectly fine. Ended up needing the vehicle towed to the chevrolet dealership. It was confirmed upon dealership inspection by the mechanic that an intake valve spring broke and locked up the engine. We currently are being denied coverage through our extended warranty with endurance to replace the engine.

I am reporting a serious safety concern involving my 2026 Chevy Traverse that occurred on May 9, 2026 at 6:46pm. While driving at freeway speed in the carpool lane with adaptive cruise control and gap assist engaged, my vehicle suddenly applied the brakes unexpectedly even though there were no vehicles directly in front of me. The nearest visible vehicle was a significant distance ahead, and there was no apparent reason for the braking event. This was not a gradual deceleration. The vehicle actively braked. I was passing under or near an overpass at the time, which makes me wonder whether the sensors misread something. Regardless, the sudden braking created a dangerous situation because vehicles were behind me, and the driver behind appeared to think I was brake checking them. This could have easily caused a rear end collision. As a result of this incident, I no longer feel I can trust these safety/driver assistance systems and have since disabled those features because I do not feel safe relying on them until this issue is properly investigated and addressed. I am requesting that this issue be formally documented, that the vehicle be inspected for any malfunction related to adaptive cruise control, automatic emergency braking, forward collision warning, or related sensor systems, and that I be advised whether this is a known issue with the 2026 Traverse. If there are any software updates, technical service bulletins, recalls, or corrective actions available, please let me know. This is a serious safety concern, and I would appreciate guidance on the next steps.
