CHEVROLET Complaints

At random times when you start the vehicle there is no sound. No sound from the turn signals, radio, emergency flashers. Apple Car Play. You have to restart the vehicle to have it reset. You always do not know there is no sound until you have started to drive and go to use the radio of notice that the turn signal is not working. I did not realize that my left hand turn signal did not turn off and at a traffic light I was going straight and a car turn in front of me because they assumed I was making a left hand turn. There was not an accident because they were able to stop. I have had it back to the dealership a number of times. They reset the system. Said it needed a global reset. Even after the reset it still is doing this. Happens more in cold weather. I have recording that are date showing no sound. I have multiple videos but I am unable to upload due to size. I was able to share them with the service technician at Gentilini Cherolet. 500 John S. Penn Blvd. Woodbine, NJ 08270. Phone Number 609-459-0014.

The contact owns a 2015 Chevrolet Colorado. The contact stated that while driving at various speeds, the vehicle experienced a sudden loss of automotive power. The power steering message was displayed on the instrument panel. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 199,106.

Valve body failed in Dec. 2024 and they replaced it. Valve body failed again in April 2025, they replaced it with new. Valve body failed again in Oct 2025, they said they will not replace it. The brakes locked up for a few seconds making a loud noise, it would not go in reverse which i showed the mechanic all three times, and it would not go over 35mph. they told me the new transmission they put in it in April of 2025, was not warrantied. This has been an on going issue since the original recall, and they refuse to fix it correctly. You will see from the documents, it has been in the shop 6 times in 10 months. now it sits in my yard because I don't want to get in a accident if it goes out while I'm driving. I can not go south for the winter like we usually do because of the truck. Chevy doesn't seem to want to fix the on going issue which was a recall.

Exhaust fell off under normal operating conditions. Dealership (Dekalb Sycamore Chevrolet- Sycamore Illinois) stated this has been a common issue with this year group of Chevrolet Trailblazer SUVs. Dealership stated the bolts/exhaust pipe junction between the catalytic converter and pipe that goes to the muffler rusts through and the entire exhaust system from the cat back falls out of the undercarriage of the vehicle, which is what happened here.

November 28th 2025 we were coming down Logan canyon in Utah at 50 miles an hour when i was passing another vehicle on the left I felt a hard shift and a prompt came on the dash that said reduced acceleration. So as I was passing the vehicle I was pulling in front of them and lost the ability to accelerate or even hold speed. I passed the vehicle got in front of them and slowed down rapidly without any ability to control the speed of the truck. At this point when I would push the gas nothing would happen so I pulled off the side of the road. While we were sitting, there was suddenly a burning smell in the cab so we rolled down the windows and made sure the doors were unlocked in case we had to jump out. We sat there for a minute everything seemed fine I checked the accelerator and it was working again so we drove home. I immediately took the truck down to John Watson Chevrolet to have it looked at. I told the service writer what had happened and she said there was a code that had been thrown however there was nothing now and since everything seemed fine I shouldn’t worry about it because the computers trip pretty easily on these new trucks. I insisted on making an appointment so she scheduled me for Tuesday the second of December. I took the truck in just before 730 today the second of December. Christina from John Watson checked me in and told me she would let me know when my truck is ready. She called me at 12:34 but I missed so she called again at 1:18 to tell me that she had some news on my truck and that it was going to need a new engine. I took her the dealership rental back and she sent me to enterprise for a 45 day rental. They have had the car for just over two weeks at John Watson Chevrolet in Ogden Utah.

When I was driving down the street, I noticed smoke coming from the hood then flames . I parked off to the side of the road and open the door and took off running away from the vehicle. Loosing everything clothes, phones , jewelry important documents. I paid off the vehicle. Was happy that for once in my life I did something good until that happen so please help on what to do . I know I didn't pay off the SUV for nothing.

For about a week and a half my car had made a high pitched wheezing/hubbing sound when started cold. This occurred at all temperatures cold and warm. Yesterday December 13th I went to run some errands and about a mile into my drive my 2021 3lt 3.6 V6 Chevrolet Blazer lost the ability to power itself. There was no electrical problem however the power train lost power all gears drive and reverse. I was able to get off the roadway without incident. I scan my check engine light and had several check engine lights including a P 0796.

The truck had a lifter failure which caused the pushrod to bend damaging the camshaft as well. I spent $5000 dollars just for the problem to happen again. I’ve have spent nearly $10000 on this issue. This not something you expect from a truck that you pay nearly $60000 for.

Vehicle experienced sudden engine malfunction including rough idle, hard misfire, and flashing check engine light. Vehicle was diagnosed with a collapsed lifter and internal engine failure. Metallic debris was found in the engine oil, including silver and gold/bronze particles consistent with bearing material. A Chevrolet dealer inspected the vehicle and determined that the engine requires complete replacement due to internal mechanical failure. Vehicle is equipped with the 6.2L V8 (L87) engine. The failure occurred without warning and presents a safety concern due to potential loss of propulsion. This vehicle is not currently included in the existing GM 6.2L engine recall, despite exhibiting the same failure characteristics reported in other affected vehicles with the same engine and year that were included in the recall. Vehicle has not been driven since metal contamination was discovered to prevent further damage

Purchased my vehicle brand new in October 2024 and around 3000 miles give or take the front brakes started to squeal. I reported the issue to the dealership on several occasions and was told this is normal due to dust, etc. I have owned 3 brand new vehicles in my lifetime and I have never had this issue with a brand new vehicle with 3000 miles or less on a vehicle; especially a vehicle purchased for almost $60,000. My vehicle currently has 17,000 miles and the squealing continues just as it was at 3,000 miles. My front brakes currently show 18% brake life left on the dash in the vehicle status. This is unheard of for a brand new vehicle to be needing brakes this soon. Which would explain the squealing brakes, they have placed cheap brakes, rotors, etc on this new model. If it weren't for this vehicle status feature showing the life remaining for each component, I could possibly unknowingly experience brake failure and would not have been aware that the brakes were at the end of life so soon; almost less than a year from purchase. This issue needs to be addressed with the manufacturer and looked into before someone driving a brand new vehicle, thinking they still have good brake life ends up killing themselves or someone else due to brake failure.
