Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints 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.

Brakes lines broke while in traffic at stop light. Manage to drive in low gear 1/2 block to repair shop. They replaced the lines

NHTSA ID 11606301 · filed Aug 3, 2024

SITTING AT A STOP LIGHT THE BRAKES FAILED. HOLDING THE BRAKE WHILE WAITING FOR THE LIGHT TO CHANGE, THE PEDAL ALL OF A SUDDEN WENT TO THE FLOOR. WHEN I BEGAN MOVING I HAD TO KEEP THE TRUCK BELOW 30 MPH TO ALLOW THE BRAKES TO WORK WITH INCREASED STOPPING DISTANCE FACTORED IN. AFTER ABOUT A 5 MILE DRIVE HOME, CHECKED THE BRAKES AND NOTICED A LEAK FROM RUSTED BRAKE LINES NEAR THE DRIVER'S DOOR. TRUCK CANNOT BE SAFELY DRIVEN UNTIL RUSTED LINES ARE REPLACED. NO ABILITY TO MAKE A REGULAR STOP MUCH LESS AN EMERGENCY STOP IN THE PRESENT CONDITION.

CHEVROLET AVALANCHE INSTRUMENT CLUSTER FAILURES. OVER THE PAST 32 MONTHS THE INSTRUMENT CLUSTER ON MY 2003 AVALANCHE HAS BEEN INTERMITTENTLY MALFUNCTIONING CAUSING THE SPEEDOMETER, FUEL, TEMP, OIL PRESSURE AND ALL OTHER GAUGES TO NOT OPERATE. AS OF 1/19/2008 ALL OF THE GAUGES ON THE INSTRUMENT CLUSTER FAILED COMPLETELY. FROM WHAT I UNDERSTAND CHEVROLET HAS ISSUED A EXTENSION OF THE WARRANTY TO 70,000 MILES FOR THIS SINGLE ISSUE BUT THIS IS A SAFETY RELATED PROBLEM THAT SHOULD BE TAKEN CARE OF UNDER A RECALL OF ALL VEHICLES WITH THIS INSTRUMENT CLUSTER. *TR
