Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

"While attempting to merge onto a high-speed freeway on-ramp, the vehicle suffered a sudden and catastrophic loss of engine power, rendering it unable to accelerate and creating an immediate life-threatening safety hazard. The vehicle was restarte and driven home, where an onboard diagnostic check revealed an emissions system failure. The dealership later confirmed that BOTH close-coupled catalytic converters on the 3.6L V6 were damaged. The check engine light was a solid light. Not flashing.

Radiator leak from the bottom left corner (driver side). Slow leak over time, no visible damage (per the service department), likely a manufacturing issue. Entire radiator required replacement.

On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.

Transmission & engine failure. Press the gas and it doesn’t move the car-feels as if it is trying to change gears and it isn’t working. Car under warranty & still not working. Been to the dealership multiple times and they are unable to fix the issue. No warning signs.

The contact's daughter rented a 2024 Chevrolet Blazer. The contact stated that while his daughter was driving at an undisclosed speed, after driving over a small imperfection in the roadway, there was an abnormal scraping sound coming from underneath the vehicle. The driver pulled over to the shoulder of the roadway. After a visual inspection, the contact observed that the exhaust mounting bracket had disconnected. The vehicle was taken to an independent mechanic by the rental company, and the vehicle was repaired; however, the contact’s daughter was not provided with the diagnostic results. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 29,000.
