CHEVROLET Complaints

The thermostat malfunctioned causing an error message regarding “steering assist is reduced”. When I parked and turned off, the engine fan continued to run. When car was restarted, the temp gauge inside was stuck at C. Took to dealership and they assessed. They repaired the thermostat under power train warranty, however there was a crack in the radiator (top) resulting in the need for a new radiator. This vehicle had 35,000 miles on it. Upon research online, it seems there are MANY people who have had this same issue and worse. It appears cars produced during COVID era are most affected. Chevy refused to warranty the issue. The dealership offered a small cost reduction (due to our loyalty). The thermostat and the radiator issues seem to be well known by Chevy, they just refuse to accept responsibility. Now we are out thousands of dollars on a basically “new” vehicle.

The vehicle was pushed to a safe place. The check engine warning light illuminated after the failure. The contact associated the failure with NHTSA Campaign Number: 23V172000 (Power Train). The vehicle was towed on a flatbed to the local dealer. The vehicle was not diagnosed or repaired. The dealer provided an estimate for the transmission replacement. The manufacturer was contacted and confirmed that there was no recall coverage on the VIN for the failure. The manufacturer referred the contact to the NHTSA Hotline for assistance.

While flat towing my pickup truck behind my motorhome, on interstate 94 eastbound, in Minnesota I noticed smoke on my screen in the motorhome back facing camera. I safety pulled over to a truck rest area in Avon Minnesota. I went to investigate and realized that the pickup truck had flames coming from underneath the hood. Because of the fire and heat I wasn’t able to release the pickup truck from the motorhome which ultimately caused the Motorhome to catch fire as well. Police and fire department were called and both the Motorhome and pickup truck were totaled. My insurance company has possession of both vehicles. I previously had electrical problems with the pickup truck and took it to the Chevy dealership to address the issue. Evidence of module overheating with traces of burn were found on one occasion. I’m uploading photos of the police report and work orders from the dealership. No one was injured but all of our belongings were destroyed or damaged from the fire. We were left with nothing but what we had on at the time.

Chevrolet has a recall on some vehicles for a bad transmission valve body, but my vehicle isn’t a part of the recall and I’m having the exact same issues. Currently my only vehicle that I have to transport my 7 month old is a complete safety risk. My check engine light is on and the code its throwing is to replace transmission valve body assembly. My Tahoe is shifting very harshly when driving normally, it feels like it slams into gears causing the whole car to jerk. When sitting at a red light that turns green, Tahoe is slipping, barely wanting to move through an intersection with vehicles all around me. I’ve been advised to not drive my Tahoe at all because if I do I will certainly have severe drivetrain damage and rear wheel lock up. Like I said, Chevrolet already has a recall for this issue on some of their vehicles, but my specific Tahoe does not. This is my only vehicle for myself and my baby and I cannot drive it due to its safety issues.

The contact owns a 2020 Chevrolet Blazer. The contact stated that while driving approximately 70 MPH, the message, "Steering Assist Reduced - Drive Carefully” was displayed. The contact stated that the A/C shut off and the windshield defroster failed after the message was displayed. The vehicle was taken to the dealer, and the contact was informed that the repair was not covered. The manufacturer was informed of the failure and confirmed that the vehicle was not included in the “Special Coverage" for the repair. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 65,000.

The vehicle experiences a constant cooling system failure that appears to be related to the thermostat. Beginning at approximately 40,000 miles, the engine cooling fan started running continuously at high speed whenever the vehicle is operating. At the same time, the air conditioning stopped functioning properly and the vehicle began displaying a warning message indicating that steering assist is unavailable or reduced. The vehicle is available for inspection upon request. This condition creates a safety concern because the steering assist warning indicates a potential reduction or loss of power steering assistance, which could increase steering effort and make the vehicle more difficult to control, particularly during low-speed maneuvers or emergency situations. The warning appears during normal vehicle operation and can distract the driver. The ongoing failure of multiple vehicle systems raises concerns about the safe and reliable operation of the vehicle. The problem has been present continuously since first appearing at approximately 40,000 miles and is fully reproducible. The condition occurs every time the vehicle is driven and has not corrected itself. Symptoms include the engine cooling fan running continuously, loss of air conditioning, and a steering assist warning message. Based on reports from other Chevrolet Blazer owners experiencing similar thermostat-related failures, this may represent a common defect that warrants investigation and consideration for a safety recall.

While driving, my 2019 Chevrolet Silverado 1500 with the 5.3L V8 suddenly lost engine power approximately a quarter mile from my home. The vehicle has only 35,000 miles. A check engine light indicated a misfire, and I confirmed cylinder 7 was misfiring. I replaced the spark plug, plug wire, and coil pack, but the misfire continued. The dealership diagnosed a failed lifter in the Active Fuel Management (AFM) system and is disassembling the engine to assess further damage. This matches the widely documented AFM lifter failure pattern in GM 5.3L V8 engines. The sudden loss of motive power while driving created a safety hazard. All maintenance was performed at GM dealerships.

The paint on this vehicle is horrible. Now I am upside down in the vehicle and unable to get anything close to what is owed. No one affiliated with GM/Chevy will take any responsibility

Driving down the highway at 60mph, dash started blinking for trailer brake service needed. Was not trailering anything. Within 3 seconds I had smoke filling the cab, pulled over and got out. Within 3min truck was fully engulfed totally gone. God forbid I was alone but even at that I did not have time to get many things out and keep imagining what a different day I’d be looking at if there were kids with me.
