What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1987 Pontiac Bonneville, grouped by the component NHTSA recorded on the report.

THE CAR WILL MOMENTARILY HESITATE WHEN ATTEMPTING TO ACCELERATE FROM A STOPPED POSITION. IT IS PERIODIC AND NOT CONSISTENT, THEREFORE, HARD TO DUPLICATE ACCORDING TO THE DEALER. I ASKED GM TO E-MAIL SOME OF THEIR NATIONWIDE PONTIAC DEALERSHIPS AND ASK FOR THEIR INPUT ON THIS TYPE OF PROBLEM BUT THEY REFUSED. THIS CAN BE A VERY DANGEROUS SITUATION WHEN ENTERING MOVING TRAFFIC. SO MUCH FOR CUSTOMER SERVICE. I WILL REMEMBER THAT WHEN I PURCHASE MY NEXT VEHICLE. *JB
