NHTSA Complaint #10221819 — 2005 PONTIAC GRAND PRIX

I ALMOST CRASHED MORE THAN ONCE BECAUSE THE VEHICLE ACCELERATES AT FULL THROTTLE ON IT'S OWN. PERSISTENT ISSUE. WHEN DRIVING ON THE EXPRESS WAY WITH THE CRUISE CONTROL ENGAGED, THE VEHICLE ABRUPTLY ACCELERATES AT FULL THROTTLE, RPMS SHOOT TO THE RED LINE, AND AT TIMES THE CRUISE CANCELS THEN RESUMES (AT FULL THROTTLE) ON ITS OWN ERRATICALLY AND REPEATEDLY WITHIN A DURATION OF LESS THAN A COUPLE OF SECONDS. THIS HAPPENS AT 70 MPH AND ALL OTHER SPEEDS EVEN AT 25 MPH. ALMOST CRASHED SO MANY TIMES. WHEN THAT HAPPENS, THE SPEEDOMETER REPORTS RANDOM VEHICLES SPEED. I HAVE SENT AN EMAIL TO GM THROUGH THEIR COMPLAINT SECTION AT PONTIAC.COM WITH NO FEEDBACK. DEALER DID A COURTESY DTC CHECK WITH NO LUCK. MY MANUFACTURER WARRANTY JUST EXPIRED, AND I'M NOT WILLING TO PAY THE DEALER TO FIX GM'S DESIGN PROBLEM AT MY EXPENSE. *TR
