CHEVROLET Complaints

2019 Chevy Blazer. Car would not turn off the electrical components when parked. Put car in park and walked away and there is a warning note that says, "Shift to Park." But the car was in park. Called Chevy and they know about the issue on the 2019-2023 vehicles. They sent me the Technical Service Bulletin. Back in 2020, the car had the shifting harness and button replaced and we just had to have it replaced again because it is a consistent issue with the vehicle. Except this time, the dealer charged us $668.40 to fix it! It is a known issue by the company and THEY sent me the service bulletin to get it fixed. It should have been covered by Chevy, or, at least a recall should be instituted. The power to the car wouldn't shut off. We were able to jump the car to get it started again.

The contact owns a 2020 Chevrolet Colorado. The contact stated that while operating the vehicle, the check engine warning light remained illuminated. The vehicle was taken to an independent mechanic, who diagnosed the vehicle with camshaft position sensor failure. The contact was informed that the camshaft position sensor needed to be replaced. The vehicle was not repaired. The local dealer and manufacturer were notified of the failure, but no assistance was provided. The contact was informed that the VIN was not under a Manufacturer Extended Warranty coverage related to the failure. The failure mileage was 119,000.

On Friday March 20, 2026, we traded in a Chevy Equinox to get a newer model which is the VIN number we listed in this complaint. Driving home from the dealership the vehicle went from drive to park on its own (driving at 65 miles/hr) and my husband had to immediately put the car physically back into drive. Once we finally got the vehicle to our house, I went out to check it, and the vehicle would not even start. Every single light came on yet it would not start up. We called On-Star and they couldn't do anything and told us we'd have to take it to the dealership. We finally got it to start up again, but the check engine light never went off. The next day my husband was able to get it started and immediately took it back to the dealership it was bought from, which it was actually transferred to from another dealership within the state, but on the way to the dealership we bought it from the car went into park on its own 5 more times, very dangerous and unacceptable. Once the car made it to the dealership, they could not even get the vehicle to shut off once they pulled in into the service area. My husband luckily is a professional driver, but is this was someone not as familiar or calm, this could have been a horrible catastrophe.

Master Brake Cylinder is defective. Multiple caution lights illuminated. (Service ESC, Service Brake Assist, Cruise Control Inoperative) Ed Morse Chevrolet and Brad Deery Motors have both confirmed the brake cyclinder being defective. Ed Morse advised not ordering the same brake cylinder as they are known issues from factory, they advised me to wait for the recall or a re-engineered part to be produced by GM. Brad Deery Motors knew nothing about this and they are currently putting the OEM master brake cylinder back on the car. I believe they are putting a known defective component back on my brand-new vehicle. There is currently a law suit in Pennsylvania.

Well taken care of 2020 trailboss upper control arm completely failed driving down the interstate with family in the truck. Suspect defect from ball joints. Only 68k miles. No warnings. Tire fell into suspension causing thousands in damage. Had to be towed. At high speed we could've all been killed. Seen multiple reports online of similar ball joint/ control arm failures. This needs to be addressed ASAP! Very dangerous.

On February 12th, the check engine light came on in my 2021 Chevy Silverado 1500 with the L87 6.2 L engine. The following morning, I took it to the shop and had it checked. It was diagnosed with crank shaft bearing coming apart. I contacted the dealership and they told me that my VIN was not associated with the L87 recall, but that they would see if GM would be willing to help with the costst associated with replacing the engine. They agreed to pay for about 30% of the repair. I pointed out to them that my engine was manufactured in the Tonowanda, NY plant which is the site where many of the recalled engines were manufactured. They still refuse to cover the cost of the new engine. I feel that they should cover my costs since the engine was manufactured in the plant and broke down for the exact reason for the recall. My costs are over $10,000 due to their defective engine. Please add my VIN to the recall.

The contact owns a 2018 Chevrolet Traverse. The contact stated that upon parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed while the gear shifter was already in park(P). The contact stated that the vehicle responded after several attempts to shift to park(P). The dealer and the manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was approximately 81,000.

The lane keep assist never works properly, it vehicle doesn’t stay in lane, also gps has never worked properly, it’s been to the dealers several times and parts have been replaced with out any success

Engine failed, started making noise and was shutting off, engine was locking up.

My Equinox completely stopped functioning in the middle of a major intersection as I was making a left turn during 5pm traffic. I was able to push the car out of the intersection with the help of other drivers (they had to exit their vehicles to assist) and the car restarted - I drove back roads to chevy dealership with the car cutting out unexpectedly twice more while the vehicle was moving and then restarting. No warning light came on. Dealership said my fuel pump "exploded" and pieces were also caught in the fuel injectors and all had to be replaced.
