CHEVROLET Complaints

The check engine light came on on my Chevy Tahoe, November 2023. The system started to fail it would say for collision not able service ESC system. I would bring it into the shop. They would hook it up to the computer and they would say oh nothing wrong we just reset it. Then it started to shut down and it would say proceed with caution, low acceleration, no front and collision service ESC and I would have. Luckily I was in a city so I took it to the shop. They gave me a print off. Said there was no technician cleared it. I was able to make it home and I made an appointment. They put it on the computer. they said oh nothing‘s wrong. Everything‘s fine then it did it again and I was going through the mountains. I noticed that my car smelled of gas and that the gas gauge was just sucking fuel and I knew this was a problem.. they finally found out what was going on, but I feel the damage had already been done. The part that got replaced was over $1000. I had to pay out-of-pocket for it. Now my vehicle’s engine is shot.

The transmission consistently fails to shift properly, hanging between Drive and Overdrive. The dealership initially diagnosed the issue as a faulty torque converter & lines, then a tow/haul switch, and replaced it; however, the failure persists. The transmission now requires full replacement. I believe this is a known manufacturing defect present prior to the vehicle's release. Additionally, the lifetime powertrain warranty originally attached to the vehicle has been removed from GM's records. This hesitation causes unpredictable acceleration and loss of power, creating a significant safety hazard when merging onto highways or navigating heavy traffic. It is available for inspection upon request.

After diagnostic troubleshooting from DTCs on a check engine light, it was discovered that the brake vacuum pump connected to the engine was completely nonfunctional. Previous symptoms included stiff brake, loss of brake power at random brake periods which could have cause and accident with other drivers, and finally malfunctioning sensors attributed to the exhaust system. This also led the vehicle to be unable to pass state regulated Emissions testing because of the inability to maintain proper emissions levels. Brake Vacuum pump that was removed from vehicle to inspect and diagnose is still available for inspection. Recent findings show that Chevrolet/GM is aware of the issue in their vehicles but refuses to address or replace faulty brake vacuum pumps. It is a common problem amongst 2013-2022 Chevrolet Malibus. Vehicle that is in question was inspected by a certified mechanic shop with failed emissions test. Solid check engine light appeared once the brake had become harder to push and stop the car. OBD scans show DTC codes that were pertaining to MAF and MAP malfunctions in readouts and communications to the ECM. After further inspection, the ABS module had been acting as "backup" for hydrolic brakes system that had zero vacuum to power the brake booster, this could have caused the engine to stall, longer than normal stopping distances (stronger risk of rear ending other drivers), and multiple components and sensors to fail, requiring them to also be replaced.

The power brake booster failed suddenly causing the brake petal to become hard. Almost caused an accident as I suddenly lost the ability to brake. There was no warning prior to the failure. After the failure a service warning for brake assist appeared. The vehicle was been inspected by an auto service provider.

Engine locked up without warning while driving down the highway, resulting in a loss of power steering and not ability to accelerate.

I was driving at a low rate of speed after leaving my house and the instrument panel (dashboard) screens went completely blank. It was as if the computer system was resetting/rebooting. Within a few seconds, the instrument panel screen started working again and I could see the instrument panel readings. It was unnerving as I had my daughter with me. This is the second time the instrument panel has gone completely blank. The first time was in July 2024, and I filed a report with NHTSA in complaint number 11677778. That complaint generated no recall for my vehicle even though there is a recall NHTSA ID: 23V744000 for 2024 Chevrolet Trax vehicles with the same problem I have now have had twice. Since this problem has occurred twice, and there is already a recall on 2024 Trax vehicles for the problem I am reporting, there is an electrical system issue that should be corrected as it is clearly a safety issue.

The braking system on my 2015 Chevy Suburban LTZ failed at slow speeds in a parking lot. I have replicated the issue in both forward and reverse. My family's safety was put at risk in that while backing up out of a parking spot the brakes failed completely and I had to push extremely hard on the brake to get the vehicle to stop. That same behavior occurred while pulling forward into a parking spot, almost hitting the car in front of me. I took the vehicle into a Chevrolet dealer today indicating the symptoms and they said there was no recall attached to my VIN. This exact same behavior in my vehicle is described in [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The automatic transmission on my 2019 Chevrolet Tahoe has failed prematurely at approximately 88,000 miles. The dealership confirmed internal transmission damage, specifically that Solenoid #3 in the valve body is sticking and not engaging, which requires a complete transmission replacement. Their written inspection states: “Possible internal damage in transmission. Solenoid 3 in valve body is not engaging.” The component is available for inspection upon request. Safety Risk: This malfunction created several dangerous situations. The vehicle hesitated, struggled to shift into gear, and at times moved forward while in reverse. These symptoms could cause loss of control, delayed acceleration when entering traffic, or unexpected movement putting myself and others at risk. Diagnosis Confirmation: Yes. The problem has been fully inspected, reproduced, and confirmed by an authorized Chevrolet dealership service center. They provided a written estimate of $8,669.59 for a complete transmission replacement. Inspection by Others: The transmission has been inspected by the dealership where the vehicle was purchased. No independent mechanic, police, or insurance representative has inspected it yet, but the dealership’s findings are available. Warning Lamps or Symptoms: Prior to the failure, I experienced hesitation, difficulty engaging gears, harsh shifting, and the vehicle lunging forward while in reverse. Shortly after these symptoms appeared, both the check engine light and tire pressure light came on. Additional Context: GM has released multiple Technical Service Bulletins (TSBs), including 19-NA-153 and 21-NA-199, addressing known issues with their 8-speed transmissions such as harsh shifting, slipping, and valve body/solenoid problems. This suggests a broader pattern of defects. GM and the dealership offered only 10% goodwill assistance, leaving almost the entire repair cost to the consumer, despite this being an internal mechanical defect with normal personal use.

Heat blowing cold for all passengers and defrost fails to clear windshield as stated in FMVSS-103. After reviewing forums it seems that this is a known issue/common failure.

Vehicle: 2015 Chevrolet Spark, odometer <79,000 miles Component that failed: Continuously Variable Transmission (CVT) – pulley damage causing complete loss of propulsion.What happened: While driving, the vehicle suddenly lost all motive power with no ability to accelerate. The transmission would not engage in any gear and the car became inoperable in traffic. This is the exact failure described in GM Special Coverage Bulletin N192271110 (pulley damage in 2014–2015 Spark CVT). Safety risk: Complete and unexpected loss of propulsion created an immediate safety hazard. The vehicle could not accelerate from a stop or maintain speed, placing my 15-year-old son and other motorists at risk of rear-end collision or stranding in active traffic lanes.Dealer confirmation: RK Chevrolet in Virginia Beach, VA has inspected the vehicle and confirmed the failure matches N192271110 – full transmission replacement required (quote $6,637.19). Vehicle remains at the dealership and is available for inspection.Warning lamps/symptoms: Check-engine light and reduced-power message appeared at time of failure. No prior warnings before the sudden loss of power event. Failure occurred approximately October 2025 – only four months after GM’s 10-year/120,000-mile Special Coverage N192271110 expired on 06/11/2025.The failed transmission is still in the vehicle and available for inspection upon request.
