NHTSA Complaint #752541 — 2001 GMC SONOMA

ENGINE ACCELERATES ON ITS OWN AT TIMES WHILE VEHICLE IS IN MOTION. IF THE CLUTCH IS DISENGAGED DURING THE FAILURE, THE ENGINE WLL RUN AROUND 3000 RPM FOR APPROX. 15 SECONDS BEFORE IT RETURNS TO NORMAL IDLE. DEALER CLAIMS NO CODES AND ENGINE IS OPERATING TO SPECIFICATIONS. THEY TEST DROVE AND COULD NOT DUPLICATE THE PROBLEM. THEIR STATEMENT TO ME WAS " WE CAN NOT FIX IT IF WE DO NOT KNOW WHAT TO FIX". I ASKED THEM IF THEY HAD CALLED GMC TO TROUBLE SHOOT THE PROBLEM AND THEIR REPLY WAS YES AND THEY DID NOT KNOW AND HAD NO OTHER REPORTS OF THIS PROBLEM. I PICKED THE TRUCK UP FROM THE DEALER ON 9/21 AND DROVE IT ON 9/22 AROUND TOWN WITH NO PROBLEM. THEN ON 9/23 AFTER A 3 STOP SHOPPING TRIP, THE TRUCK INCURED THE SAME PROBLEM AS BEFORE. MY DEALER HAS OFFERED TO KEEP THE TRUCK FOR A COUPLE OF DAYS OF TEST DRIVING BUT I AM AFFRAID THAT THEY WILL NOT BE ABLE TO DUPLICATE THE PROBLEM SINCE THEY DROVE IT 60 MILES THE FIRST TIME THEY HAD IT.*AK
