DT*: THE CONTACT STATED WHILE DRIVING 10 MPH ON DIRT ROAD AND ASPHALT, THE FRONT END OF THE VEHICLE SHOOK AND PULLED TO THE LEFT. THIS WAS ACCOMPANIED BY A CLUNKING SOUND FROM UNDER THE FRONT END. DURING THIS INCIDENT, THE INSTRUMENT PANEL DISPLAYED INCORRECT INFORMATION ON EVERY GAUGE. THE TRANSMISSION WOULD NOT SHIFT PROPERLY,EITHER. THE VEHICLE BECAME LOCKED IN SECOND GEAR, AND WAS UNABLE TO BE SHIFTED OUT. FINALLY, THE BRAKES ON THE VEHICLE WERE SPONGY, CAUSING AN EXTENDED STOPPING DISTANCE FROM ANY SPEED. THE VEHICLE WAS TAKEN TO A SERVICE DEALER WHERE IT AWAITS A DIAGNOSIS.

I HAVE CONTACTED THE DEALER I PURCHASED THE TRUCK FROM AND ANOTHER LOCAL DEALER SINCE WITH MY FIRST VISIT ON 12/17/04 AT 14444 MILES WITH THE CLUNKING NOISE PROGRESSIVELY GETTING WORSE. I HAVE BEEN TOLD BY BOTH DEALERS ON EVERY VISIT THAT CHEVROLET WILL NOT REPAIR NOR REPLACE THE TRANSMISSION. PLEASE HELP. *NM

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
