CHEVROLET Complaints

On May 9, 2026, while pulling into a parking garage parking space at low speed (below 5 MPH), the brake pedal was pressed but failed to engage or slow the vehicle. The pedal was pressed completely to the floor with no resistance, and the vehicle continued moving forward until it struck a wall, causing damage to the vehicle. Earlier the same day, the brakes produced an abnormal hissing sound while pulling out of a parking space. No other symptoms or abnormalities were present prior to failure. The vehicle may also have recently received a software update, although it is unknown whether that is related to the incident. The failure appears to involve the brake system and the driver safety assistance systems equipped on the vehicle like forward collision alert, automatic emergency braking, and Dynamic Brake Support systems. The exact failed component is currently unknown and remains under inspection by a Chevrolet dealership. No warning lights, messages, or audible alerts appeared before, during, or after the incident. The automatic braking/collision avoidance system also did not activate. Because the vehicle had no braking capability at the time of the incident, the occupants and nearby pedestrians were placed at risk of serious injury. On May 10, 2026, the vehicle was taken to a Chevrolet dealership for inspection. The dealership has been unable to reproduce the issue, and no mechanical defects or diagnostic trouble codes related to the incident were identified. On May 13, 2026, the issue was escalated to the GM Technical Assistance Center (TAC) for further review, and the vehicle remains at the dealership awaiting a response to the TAC case. The dealership acknowledges similar brake-loss concerns referenced in GM service bulletins involving the 2025 Chevy Equinox and other models, including bulletin N24471431, although they stated the bulletin does not apply to this specific VIN.

Vacuum pump went out while driving down the interstate causing hard breaking. Break pedal was extremely hard to push down putting us at risk of not being able to break in time. There were on and off alerts to service breaks assist, however it was not consistently an alert. We replaced the vacuum pump and the issue seems to be resolved. The pump is not available as we tossed it in the trash.

Chevy Tahoe with 6.2 V-8 engine started making noise. Started rattling. Taken to dealership where I bought it. Oil changed found metal in the oil engine making all sorts of noise. Diagnosed to engine failure. New engine is ordered . It’s been 2 weeks and I am number 5 In order for engine replacement at the dealership

I started up my car on a cold winter morning and I heard a loud popping noise. I backed up my car minutes later and discovered puddles of oil in front of me in my driveway. I asked my husband to come out and look. He got under the car and said my oil blew out of the rear seal. I was unable to drive my car as the seal was blown. After some investigating I discovered it was the PCV valve that froze and blew out the rear seal. I discovered that Basil Ford was sent this Bulletin and told to clean the PCV valve when people brought their car in. They never reached out and told me to bring the car in to have this done. It could have been an easy fix. I also discovered by researching that people had this happen to them when they were driving on the highway and it caused them accidents. I called GMC and they are telling me my 2016 isn't in the class action suit. Basil wanted way too much money so I took it to Pep Boys and it cost me $3,000 to have the PCV valve replaced with the kit that prevents it from freezing up again and I had to replace my manifold and my rear seal

The contact owns a 2019 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the braking system became inoperable, and the brakes unexpectedly locked up with no warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed the vehicle and retrieved trouble code TSB-21NA268. The contact was informed that the brake vacuum pump connected to the crankshaft had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 61,000.

I was driving to work, when I got off the exit I stopped at Sheetz. When I got back in the car my brake pedal was stiff as a rock, and there was oil on the ground. A friend of mine does mechanic work so I called him and he said it sounds like the vacuum pump. I had the car towed to his garage, the tow costed me $400 which was very cheap considering where I was located. When I got it to the garage he confirmed that it was the vacuum pump and we removed several pieces of metal from inside the engine. I now have my car at the Chevy dealership in Chippewa PA. They told me to be $180 a diagnose it, well they just called me a little bit ago and said it's going to be another $900 to take everything apart and to truly diagnose it. I'm finding out now that GM has known about the failing vacuum pumps and they kept producing them anyways. I see there's a class action lawsuit taking place, and I am not very happy. My life was put at risk. And now I'm expected to be stuck paying this huge bill?

My husband was driving our 2018 Chevy Suburban when it suddenly stopped accelerating and he could no longer shift gears. Luckily, this happened while he was driving down a gravel road (approx 25-30mph). If he would have been driving at highway speeds, it is likely that he could have lost control of the vehicle. Our Suburban had no issues to this point and had always run well. We take it in for routine maintenance. We had it towed to a local repair shop, and they informed us that something had happened with the transmission and that it would need to be replaced. I have found several GM transmission recalls and our situation sounds similar to reference N252536750. Again we had no warning signs and had been experiencing no issues with our vehicle. If this had been something that we had been noticing problems and hadn't gotten it looked at, I can understand that maybe this had been something on going for a while that we had just missed maintenance on. However, for the transmission to stop so suddenly, I believe there must be some sort of larger failure in the transmission system.

The fuel line rusted causing it to leak. We discovered it when we had some exhaust work done on the car. No one other then myself and the people that have done the exhaust work. There was no warning of the issue.

Had steering centering go out. Data cable pinched or broken somewhere in system and transmission got out. Also 4x4 system went out.

I purchased a brand-new Chevrolet dually truck from Bomnin Chevrolet Dadeland in Miami, Florida. Since delivery, the vehicle has had serious unresolved defects and safety concerns. The truck has ongoing alignment issues that the dealership has been unable or unwilling to properly repair. The vehicle does not drive correctly and there are concerns regarding safe operation while hauling. In addition, a major issue has now developed involving the rear passenger door. The rear door does not properly close and latch securely. This creates a serious safety concern because the door may open unexpectedly while driving. I brought these issues to the dealership under warranty, but the problems remain unresolved. I was also informed that the dealership could not properly perform the alignment on the dually truck. This vehicle was sold new and should not have these defects. I am filing this complaint due to concerns about vehicle safety, defective components, and inability to obtain proper warranty repairs.
