Master cylinder failure at 15,000 miles on 4/13/2026 Safety risk of Potential brake system failure. Taken to dealership on 4/13/2026, as of today 4/16/2026, master cylinder has been replaced but now the vehicle is rejecting the part, per the dealership.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that at approximately 55,000 miles, the vehicle experienced a torque converter failure, and the torque converter was replaced under the factory warranty. The contact stated that four months later, the failure reoccurred, and the dealer declined to cover the repair. Subsequently, the camshaft failed, leading to a recommendation for a complete engine replacement. The contact stated that old parts from the original engine were installed on the new engine without authorization. Two months after the engine replacement, the transmission valve body failed while the vehicle was 237th on a back-order list. Three months after a second transmission repair, the vehicle suffered another transmission failure. The contact was informed that the transmission was new but discovered but was being charged for the installation of old, faulty parts from the original engine onto the new powertrain. The vehicle was currently at the dealer, and the contact was without transportation. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 130,000.

I was traveling at highway speeds when the engine suffered a sudden and catastrophic mechanical failure without any prior warning lights or symptoms. The engine began knocking violently, locked up and put the truck into a brief skid before freeing up, followed by an immediate loss of oil pressure and a total loss of motive power.This sudden shutdown caused a brief loss of vehicle control as the power steering assist was compromised, creating a hectic and dangerous situation while I was surrounded by high-speed traffic. I was forced to navigate across multiple lanes to reach the shoulder. Crucially, this vehicle had the L87 Safety Recall (NHTSA Recall 25V-274 / GM Program N252494000) performed on July 8, 2025. The "remedy" provided by the manufacturer—which involved an oil viscosity change and a new oil cap—failed to prevent the catastrophic bearing/crankshaft failure it was intended to address. This represents a failed recall remedy that resulted in a life-threatening safety event. The vehicle is currently at a dealership awaiting a complete engine replacement.

I was driving and car suddenly reduced speed,engine light came on and message came across dash “engine power reduced” and a text was sent to tell me I have a transmission issue. Now car won’t drive past 25-30mph dealership indicated this is a faulty gas pedal which cost over $600 to repair. Did my research and this is apparently a “known” problem common in 2016-2022. Vehicles but is not an official recall. Also dealership said only “certain” vin numbers with this problem are covered. I have a 2021 and I am not one of them. Not fair. It’s a known problem it should be fixed.

The contact owns a 2019 Chevrolet Traverse. The contact stated that while driving at various speeds over a bumpy road, the vehicle made an abnormal clunking sound. The contact stated that the sound became louder over time. The vehicle was taken to the dealer, where it was diagnosed. The dealer determined that the front lower control arms and the front suspension sway bar links needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 58,000.

The coolant control valve failed and the repair resulted in an engine oil leak which persisted for 8 weeks and still has not been repaired. The service manager at the dealership and General Motors Company are trying to figure out how to fix it but are not able to yet. They may have to replace the engine is one thing the service manager said to us this week.

The contact owns a 2024 Chevrolet Trax. The contact stated that the vehicle was taken to the dealer after the check engine warning light illuminated. The dealer diagnosed the vehicle with an EVAP purge valve failure. The contact was informed that the EVAP purge valve needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 40,000. The VIN was not available.

On or about March 14, 2026 vehicle in question stopped working, losing all power and gave a message that the vehicle was over heating and to turn off immediately. A large amount of steam emitted through the coolant reservoir that was a mixture of oil and coolant. Vehicle was towed to a manufacturer service location. The oil/coolant system ruptured damaging the radiator, thermostat, hoses and related parts. Vehicle with low mileage/hours was consuming engine oil at what one would consider a greater rate. ( 1 quart every other day). Our organization is aware that the diesel model of this truck had a recall for a oil/cooling system issue and we believe the same liability may lay with the gas version. Mileage was approximately 13,000 at time of breakdown.

Cracked (chrome) wheels on 2017 Corvette Grand Sport at 30228 miles. The tire icon appeared on the driver information display. Passenger side rear tire. After inflating the tire I took it to my dealer, Jorns Chevrolet where I purchased it brand new. Jorns is a leading Corvette dealer in Wisconsin. The dealer actually had a set of after market replacement wheels on display in the showroom. The technician removed the wheel and pointed out a large crack causing the slow leak. Not wanting to pay an exorbitant amount for one wheel and gamble on the other three I decided to replace all four with forged aftermarket wheels. Now, the technician discovered a crack in the driver side rear wheel also. Jorns explained that they have replaced wheels, with similar problems, on forty other Corvettes! Appealing to GM was a futile waste of time. GM skillfully crafted a policy to claim any sort of compensation virtually impossible. Initial contact requires the owner to deal with some appointed law firm and comply with their front line screening. IF you succeed with that, mountains of documentation are required. Very disappointing considering, the frequency of failures and owners history with a known problem with a premium brand model.

While driving at highway speed with cruise control engaged, the vehicle experienced a sudden loss of propulsion. The engine began jerking and the vehicle rapidly decelerated from highway speed (50 mph) to 10–15 mph. The transmission appeared to disengage or shift to neutral around 10 mph, and the vehicle was unable to maintain speed, creating a hazardous situation in traffic. The vehicle then shut down and displayed a message to restart the engine along with a check engine light. When attempting to restart, the engine would not turn over properly and produced a loud clicking/struggling noise, similar to a failed or seized engine. The vehicle was towed and is currently awaiting diagnosis at a dealership. This failure occurred without warning and created a serious safety risk due to sudden loss of power while driving.
