2007 Buick Rendezvous Engine Problems

SUMMARY: ON CERTAIN SPORT UTILITY VEHICLES, CONTAMINATION ON IGNITION RELAY CONTACTS CAN CAUSE HIGH RESISTANCE. THIS CAN AFFECT SIGNALS TO THE POWERTRAIN CONTROL MODULE AND, COULD CAUSE INTERMITTENT VEHICLE STALLS AT ANY TIME. CONSEQUENCE: THE VEHICLE CANNOT BE RESTARTED IMMEDIATELY. IF THIS WERE TO OCCUR, IT COULD RESULT IN A VEHICLE CRASH. *TR

TL*THE CONTACT OWNS A 2007 BUICK RENDEZVOUS. WHILE DRIVING 10 MPH, THE INSTRUMENT PANEL LIGHTS ILLUMINATED. WHEN THE CONTACT DEPRESSED THE ACCELERATOR PEDAL, THE VEHICLE HESITATED AND THEN ACCELERATED. SHE STATED THAT THE VEHICLE FELT AS IF IT WOULD STALL WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. WHEN SHE REMOVES HER FOOT FROM THE BRAKE PEDAL, SHE FELT A SENSATION AND THE VEHICLE WOULD ACCELERATE VERY QUICKLY. THE DEALER NOTICED THAT THE INSTRUMENT PANEL LIGHTS WERE ILLUMINATED AND STATED THAT THE ACCELERATOR PEDAL SENSOR WAS THE CAUSE OF THE MALFUNCTION AND NEEDED TO BE REPLACED. THE DEALER REPLACED THE VEHICLE AND STATED THAT IF SOMEONE WOULD INSPECT THE VEHICLE, THE FAILURE WOULD APPEAR. APPROXIMATELY ONE MONTH LATER, THE FAILURE RECURRED FOR THE SECOND TIME. THE CONTACT TOOK THE VEHICLE BACK TO THE SAME DEALER WITH THE FAILURE STILL PRESENT. THE DEALER STATED THAT THEY WOULD KEEP THE VEHICLE AND NOTIFY THE CONTACT OF THE SITUATION. HE ALSO STATED THAT THERE WERE OTHER FAILURES WITH THE VEHICLE, SUCH AS THE ENGINE HESITATING UPON START UP, THE RADIO MALFUNCTIONING, AND THE DOORS JAMMING. THE DEALER STATED THAT NOTHING COULD BE DONE ABOUT THE ENGINE UNTIL IT MALFUNCTIONED. THE RADIO WAS REPLACED AND THE DOORS WERE REPAIRED; HOWEVER, THE DOORS CONTINUE TO MALFUNCTION OCCASIONALLY. THE PURCHASE DATE WAS UNKNOWN. THE CURRENT MILEAGE WAS 9,800 AND FAILURE MILEAGE WAS 9,300.
