CHEVROLET Complaints

In May 2026 while driving home from her job in downtown St. Louis, my daughter was driving my equinox. While traveling on the highway at the speed limit of 55 miles an hour her brakes failed and she came within a few feet of rear ending a full gas tanker truck. She was able to maneuver to the shoulder of the highway and avoid an accident. After a few moments of the engine, idling the engine completely stopped working and shut down. After having the car towed to my local mechanic at a Midas shop, they began the diagnosis. I began similar research online to find cases of similar things happening. What was diagnosed is that the vacuum pump on the brake line was faulty and broke. Pieces of this pump made their way into my engine and ruined two of the cylinders in my engine. The car is now not drivable and needs a replacement engine. Chevy knew about this faulty, vacuum pump part and they did issue recalls on other vehicles using the same part. They have also issued technical bulletins to their technicians for a diagnosing this failed vacuum pump. I have tried to contact Chevy and they have offered me no assistance. I know a class action suit has been filed for this very same issue. Chevy is aware of this issue. Chevy‘s choice to use a part they knew was faulty. Almost led to the death of my daughter.

The OTA had the interstate lanes bottle necked down. Traffic was trying to merge. The van had already slowed down and moved into the thru lane closest to the median. The van was pushed off the road by a semi into the contrete barrier. The semi clipped the bumper on the front passenger's side. It was also hit on the driver's side rear bumper. All of this caused the van to hit the wall on the front driver's corner. The airbags did not deploy! The driver was slammed into the steering wheel hitting his face against it. He suffered several facial fractures which required surgical repair. He now has plates holding the orbital socket, cheek bone, and jaw. The fracture in front of the ear was not plated. The highway patrol was called to the scene. The van will soon be released to the insurance company for claims inspection. We believe it to be totaled

2027 CHEVROLET BOLT – SUDDEN FORWARD LURCH / PROPULSION EVENT WITH MULTIPLE COMMUNICATION FAULT CODES While driving my new 2027 Chevrolet Bolt, I was stopped at a traffic light. When the light changed, I applied the accelerator gently to move forward. The vehicle suddenly produced a loud bang or clunk and lurched sharply forward. All of the yellow instrument panel lights flashed on for a few seconds. The acceleration was abrupt and substantially different from my accelerator input. Surrounding drivers were alarmed. The event was sufficiently forceful and unexpected that I considered it a safety issue involving propulsion control. I was not accelerating aggressively; this was a gentle acceleration, in traffic, making a left turn onto a freeway ramp. I subsequently brought the vehicle to the Chevrolet dealer for diagnosis. The dealer retrieved the following diagnostic trouble codes: U164B; U164E (5 times); U0485; U11FD; P3013; U1A25; U160A (3 times)l U197A (3 times); U0159; U1126 (2 times); U1150; B1A25; U1607; U1151 Several of the retrieved codes are U-series communication/data-network codes. The vehicle has now been at the dealership for three days; so far the dealer has not provided an explanation for the sudden lurch or identified the underlying cause of the diagnostic codes. Previously the car was at the dealership for 15 days. I am concerned that an intermittent electronic, communication-network, propulsion-control, power-supply, software, or related fault could cause another unexpected propulsion event. The vehicle has also experienced charging/range abnormalities, and code P3013 was among the codes retrieved by the dealer. I do not know whether those issues are related to the lurch event, and I am not asserting that they are. I am reporting them because they may be relevant to NHTSA’s evaluation of the vehicle’s electrical and control systems. I am requesting that this incident be recorded as a potential safety defect

The contact owns a 2015 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, there was an odor of rotten eggs inside the vehicle. The odor was discovered to be Hydrogen Sulfide that was entering the cabin of the vehicle from the overcharged batteries. No warning lights were illuminated. The dealer was contacted, and the vehicle was diagnosed with PCM failure. That contact stated that the failure caused rough shifting and a loss of control voltage. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 198,000.

The contact owns a 2020 Chevrolet Colorado. The contact stated that while reversing out of the driveway, the check engine warning light illuminated. The failure recurred while driving 65 MPH. The vehicle was taken to AutoZone, where DTCs P0024 and P0014 were retrieved, indicating exhaust camshaft position system performance issues for Bank 2 and Bank 1. The contact associated the failure with GM Special Coverage Number: N232430470 (Camshaft Position Actuator Valve Solenoid - Bank 2 (Left Side) Exhaust). The vehicle was then taken to the dealer, where the diagnostic result was confirmed. The dealer swapped the camshaft position sensor actuators between both banks and cleared the codes. The contact was advised that the cause of the failure would be determined if the diagnostic trouble codes returned. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in the special coverage. The failure mileage was approximately 36,500.

2026 Chevy Silverado High Country with 13,193 miles 6.2 engine locked up on 7/29/26 and is currently at my dealer waiting on engine replacment. GM has not fixed the 6.2 liter engine failure issue's!

The contact owns a 2026 Chevrolet Trax. The contact stated that upon pulling into a parking space and depressing the brake pedal, the vehicle unintendedly accelerated, crashed into a pole, and then stopped. An unknown warning light was illuminated after the crash. The contact stated that the driver’s side air bag deployed. The contact sustained soreness and bruises from the seat belt. The contact was transported to the hospital by ambulance and was placed under observation. A Police report was filed. The vehicle was towed to a tow lot and was then towed to a Collision Center by the insurance company. The vehicle was not yet evaluated. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 3,000.

Odometer Fraud. The contact purchased a 2015 Chevrolet Impala. The contact stated that there was a mileage discrepancy after the purchase. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 182,412. It was later discovered upon checking the Title that the mileage was 186,199.

2022 Chevy Tahoe went into limp mode at 62,500 miles out of the blue and check engine light came on. At the certified Chevy dealership I was told it was the transmission control valve, Code P2732, which is a known widespread factory issue in these models. Upon further inspection, was told my transmission fluid was completely black and burned and it ruined the transmission and therefore it needs to be replaced. "Consequential Damage Policy: When a control valve body fails and stays "stuck on," it forces maximum line pressure through the system. Continuing to drive under these conditions quickly destroys the internal clutch packs, burns the fluid, and melts down the transmission." This is exactly what happened and my vehicle was never put on a recall list but clearly was a ticking time bomb.

What component or system failed? When the BCEM failed on my car, it led directly to the transmission failing as well as the PIM. I was driving normally then had a completely inoperable car with no warning. I was told to pay over $17k for repairs by the dealership because there is no recall on the transmission, but I see proof that this is a common issue among Volt users. There needs to be a recall and repair to keep the road safe. How was your safety or the safety of others put at risk? I was driving on a busy road to school when my car fully locked up, jerked like crazy, and became inoperable. If I had been somewhere like a freeway instead of in front of a school, I likely would have become badly injured when the wheels stopped even turning. The tow truck even had to use wood under my wheels to get it onto the tow truck. Has the problem been reproduced or confirmed by a dealer or independent service center? I took it to the dealership and worked only with them. They replaced the BCEM without charge but have left me with an inoperable vehicle because I am unwilling to pay twice the cost of the car to repair it. Has the vehicle or component been inspected by the manufacturer? Dealership. But also, as mentioned, this is clearly common and needs to be recalled. A 2018 car with 117k miles of gentle driving on a well maintained vehicle shouldn't be failing, and there shouldn't be so many Volts being sold for parts because their transmission failed. This is clearly a dangerous issue related to production and should have a recall. Were there any symptoms of the problem prior to the failure, and when did they first appear? I bought the car with just under 16k miles in 2021 and within 3 months I had symptoms, but the dealership couldn't figure them out, as they happened intermittently and only in heat, and the dealership always sent me away without repairs. The failure itself happened at 62°, but was foreshadowed by lesser versions of its demise.
