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.

ON A 1999 GMC SIERRA PICKUP THE ABS MODULE FAILED AT 26,000 MILES. IN RESEARCHING THIS PROBLEM IT APPEARS THEY FAIL ON MOST SIERRA AS WELL AS CHEVROLET PICKUPS. THE REPAIR COST QUOTED ME RANGES BETWEEN $975 AND $1000. ONE SERVICE MANAGER CANDIDLY TOLD ME IT IS A SERIOUS PROBLEM THAT GM SHOULD HAVE RECALLED. *JB

FOR THE LAST TWO YEARS I HAVE HAD TO UNPLUG MY ABS BRAKES SYSTEM ,BECAUSE IT WOULD CONTINUOUSLY RUN. IF I DID NOT UNPLUG MY BATTERY WOULD DIE. THIS PAST CHRISTMAS 2004, I LOST MY BACK END COMING DOWN HILL AND LUCKILY RECOVERED. I HAVE CONTACTED GMC AND ARE STILL WAITING FOR AN ANSWER. MY QUESTION IS "IF YOUR DR PUT YOUR PACE MAKER ON THE OUTSIDE OF YOUR BODY AND IT FAILED DUE TO CORROSIVE EXPOSURE WOULD YOU HAVE A CASE. THE ABS MODULE SITS EXPOSED TO CORROSIVE ELEMENTS IN THE SALT BELT UNDER THE DRIVERS SEATOUTSIDE OF THE VEHICLE. I HAVE JUST HAD THIS PROBLEM DIAGNOSED , AND THE DEALER STATES THE MODULE AND CONNECTOR IS SO CORRODED FURTHUR DIAGNOSTICS CANNOT BE PERFORMED. THIS MANUFACTURED DEFECT SHOULD NOT BE A PROBLEM PASSED ON TO CONSUMERS; UNLESS GMC STATES"IF YOU LIVE IN THE SALT BELT DO NOT PURCHASE THIS VEHICLE". FROM 99 TILL NOW THIS SHOULD NOT AND WOULD NOT HAPPEN IF THEY JUST PUT THE MODULE UNDER THE DRIVER SEAT INSIDE THE VEHICLE. THIS PROBLEM WILL COST 1088.64 TO FIX. I WANT TO SEE IF GMC IS WILLING TO MAKE GOOD!!!

Too few reports in this category for a page of its own — they appear in the full complaint list.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
