Service Brakes, Hydraulic › Antilock/Traction Control/Electronic Limited Slip

Filed Sep 21, 2005120,000 milesMI

DT: THE CALLER'S VEHICLE SAYS WAS SLOWING DOWN ANTI LOCK BRAKES KICKED IN. THERE WAS A NHTSA RECALL 05V379000 ON THIS MODEL FOR OTHER YEARS, BUT NOT FOR 1998 MODEL YEAR. DEALER HAS NOT BEEN CONTACTED YET. MANUFACTURER SAID THEY WOULD FIX IT, BUT THEY CHANGED THEIR MIND ON FIXING IT FOR FREE BECAUSE IT WAS NOT RECALLED. THEY SAID TO GET A DIAGNOSTIC TEST AND THEY MIGHT PAY FOR PART OF THE REPAIR. THE CALLER SAID HE COULD GET IT FIXED CHEAPER THAN THE OFFER GMC MADE.*AK

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
