CHEVROLET Complaints

I own a 2019 Chevrolet Silverado with approximately 84,000 miles. Prior to the engine failure, I noticed abnormal engine ticking noise, especially during cold starts. I reported this concern to the dealership during a service visit. The technician verified the engine noise but stated that the noise was normal and no repairs were performed. Over time the condition worsened and the vehicle began experiencing engine misfires and internal engine damage. Diagnostic inspection later revealed oil contamination and cylinder wall scoring requiring full engine replacement. Additionally, while driving on a public street, the serpentine belt suddenly came off the engine without warning. This created an immediate safety concern because the belt powers critical systems such as power steering and engine cooling. Losing these systems while driving could cause loss of vehicle control. At the time of the incident, my children were in the vehicle and there were pedestrians and other drivers on the road. The sudden mechanical failure created a dangerous situation that could have resulted in a crash or injury. No warning lights or messages appeared on the dashboard prior to the engine failure, and the check engine light never illuminated. Because the engine concern had previously been reported and dismissed as normal, the problem continued to worsen until catastrophic engine damage occurred. I am submitting this complaint because I am concerned that this may not be an isolated issue and that similar engine failures could pose a safety risk to other drivers.

On Monday, April 6th, I was turning into a parking lot and the braking system, specifically the anti-lock braking system (ABS) and electronic brake control module, appeared to malfunction. While driving, I received a warning indicating the ABS was off, and the brake pedal became soft with reduced stopping ability. The check engine light also came on. I had to coast the vehicle to a complete stop. The vehicle is available for inspection upon request. The loss of normal braking function significantly reduced my ability to stop the vehicle safely, increasing the risk of a collision. This created a dangerous situation for myself, passengers, and other drivers on the road. Brake failure at any speed presents a serious safety hazard.I am aware of similar complaints reported for this issue. My vehicle was towed to and inspected by a dealership where it sat overnight before being diagnosed; however, they were unable to reproduce the issue at the time of service. Despite this, the braking failure did occur and remains a safety concern. The service advisor told me to "bring it back if it happens again" and that it "lost communication with the EBCM" which sometimes happens. The vehicle has not yet been inspected by the manufacturer directly, police, or insurance representatives. There were no warning lamps or other symptoms of this problem prior to the failure.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving approximately 45 MPH, the check engine warning light illuminated, and the message “Reduced Acceleration - Drive Safely” was displayed. The vehicle then started shaking abnormally. The contact pulled into a nearby parking lot, turned off the vehicle, and waited for a while before restarting the vehicle. After restarting the vehicle, the warning lights remained illuminated, and the vehicle continued to shake abnormally. The vehicle was taken to Auto Zone, where a certified mechanic diagnosed the vehicle and determined that there was a bent rod inside the engine. The vehicle was not repaired. The vehicle was taken to the dealer, who confirmed the diagnostic result and that the failure was causing additional damage to the crankshaft. The dealer determined that there was a misfire in the engine and that the valve lifter was malfunctioning. The contact was informed that the lifter and the camshaft needed to be replaced, and the engine needed to be repaired. The vehicle was not repaired. The contact researched and became aware of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was informed of the failure and confirmed that the VIN was not included in the recall. The contact was referred to the dealer to inquire about a Goodwill Repair for which the contact could be reimbursed if the VIN was later added to the recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 100,000.

Excessive oil consumption with no warning light, loss of power, and stalling. Also caused the master seal to leak and plugged the PCV valve. I have records for the repairs. It continues to excessively use oil and is not a reliable vehicle. When it stalls, power steering is lost as well as the stabilitrack.

MY CAR STARTED TO USE A LOT OF OIL, AND UPON MY REGULAR OIL CHANGES IT WOULD ALWAYS BE VERY LOW, BUT OIL WAS NOT LEAKING OUT OF THE CAR. IT GOT TO THE POINT THAT I HAD TO PUT OIL IN OFTEN TO OPERATE THE CAR. IT GOT TO THE POINT THAT IT WOULD CUT OFF ON ME IN SCHOOL LINES. AFTER DEALING WITH THIS OVER A PERIOD OF TIME IT SOUNDED SO BAD THAT THE EXPRESS OIL CHANGE FACILITIES REFUSED TO CHANGE MY OIL BECAUSE THEY SAID IT WAS AN ENGINE PROBLEM. SO I HAD NO OTHER CHOICE BUT TO PURCHASE ANOTHER VEHICLE 2 MONTHS AFTER TOWING IT HOME. I HAVE 2 VEHICLE PAYMENTS, MY 2017 EQUINOX BEEN DOWN OVER A YEAR NOW. PLEASE ADD MY VIN # TO THE RECALL. IM EXPERIENCES THE SAME SYMPTOMS

The contact owned a 2015 Chevrolet Colorado. The contact stated that the vehicle was driven and parked in the garage. Upon exiting the vehicle, the contact noticed an abnormal burning smell and smoke coming from under the hood. It was unknown whether a warning had illuminated. The contact opened the hood and noticed that the engine compartment had caught on fire. The contact closed the hood and attempted to restart the vehicle to drive out of the garage; however, the vehicle failed to restart. The contact shifted to neutral(N) and was able to push the vehicle out of the garage. The contact stated that the vehicle burned significantly from the front end to the windshield. The fire was extinguished by the fire department. No fire department report was filed. No police report was filed. There was no injury sustained. There was no property damage. The contact stated that the vehicle was a total loss and was in the process of being towed to a salvage yard. The vehicle did not have full insurance coverage but had liability coverage. The dealer and the manufacturer were not contacted. The failure mileage was approximately 124,000.

Electric-Release Tailgate opens unexpectedly on its own, when vehicle is put in park. This had happen when a trailer was hitched and now has caused a dent in the tailgate. There is a recall # N232426400/N232426401; but apparently my VIN is not showing in the recall.

Power tailgate opens and closes by itself. Safety of others is at risk if materials fall out on the road while driving if the tailgate opens by itself. There has been a recall for this but my truck vin is not included yet had the same issue. No warning when tailgate started having issues.

| Issues first appeared recorded on 3/9/2026, while odometer read 49,663 miles. Check engine light was caused by error codes P0128 and P01F0. This causes the following issues: * Check engine light to appear on the dashboard. * Engine temperature gauges to be unreliable at times or completely non functional at others, as it will constantly read the engine temperature "Cold". * Air conditioning unit to become unreliable at times or completely non functional at others, and only blow hot air. * Radiator fan will be stuck running at max speed despite current engine temperature. * A "Reduced Steering Assist" message will periodically appear on the dashboard. * A "Service ESC" message will periodically appear on the dashboard. * Remote start will becomes non functional. | Car was taken to a license Chevrolet dealership and had full thermostat housing and thermostat sensors replaced. Dealership confirmed all replaced parts are working correctly and as intended. After picking up the vehicle from the dealership, and driving car for roughly 30 miles, the check engine light appeared on the dashboard again causing all previous issues to return. | Several other Chevy Blazer 2020 owners have complained of the same issue online, and in forums such as: [XXX] . | INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
