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.

I PURCHASED THIS TRUCK NEW IN 1999 AND HAVE WATCHED IT RUST AWAY. WHY THEY DIDN'T USE BETTER METAL OR EVEN STAINLESS STEEL. MY BRAKE LINES HAVE RUSTED SO BAD THAT ONE OR MORE IS LEAKING ALONG FRAME RAIL UNDERNEATH DRIVERS SEAT. MANY OTHER OWNERS IN THIS REGION SEEM TO HAVE SAME PROBLEMS. I'M GLAD IT WAS IN MY DRIVEWAY WHEN IT BECAME DANGEROUS TO DRIVE. ALSO THE ABS MODULE STOPPED WORKING AND HAD TO PULL THE 60 AMP FUSE TO DISCONNECT AT 60,000 AND TRUCK NOW HAS 121,000 MILES. GMC SIERRA 1500 4WD BRAKE LINES ARE RUSTING AWAY WHAT A SHAME. DRIVESHAFT GOING TO REAR AXLE IS MADE OF ALUMINUM AND LOOKS BRAND NEW STILL. AGAIN STAINLESS STEEL SHOULD HAVE BEEN USED FOR IMPORTANT BRAKE LINES. JUST WONDER HOW MANY ACCIDENTS HAVE OCCURRED DUE TO THIS PROBLEM. THAT IS ALL AND HOPE FOR A RECALL. *TR

BLEW A BRAKE LINE WHILE BACKING A BOAT INTO THE WATER..... THANK GOODNESS NO ONE WAS IN THE WATER AND THAT THE TRUCK STOPPED BEFORE COMPLETELY SUBMERGING. THE BRAKE LINES ALL LOOK TERRIBLE.... I'M NOT A MECHANIC BUT I DO MOST OF MY OWN MECHANICAL WORK ON MY TRUCKS ALL MY LIFE.... ONCE I PAID ATTENTION TO THEM, ALL OF MY BRAKE LINES ARE IN HORRIBLE SHAPE!! BAD NEWS HERE.... PEOPLE ARE GONNA DIE FROM THIS. *TR

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.
