NHTSA Complaint #10722254 — 2006 CHEVROLET MALIBU

VEHICLE STALLS INTERMITTENTLY WHEN STOPPED AND IDLING. THIS OCCURS WHEN BACKING UP AND ALSO WHEN IDLING. IT SEEMS TO OCCUR MORE SO WHEN THE AIR TEMPERATURE OUTSIDE IS VERY HOT. USUALLY WHEN IT IS AROUND 85 - 90 DEGREES OUTSIDE. VEHICLE USUALLY RESTARTS OK. ONLY ONE INSTANCE WHEN ENGINE WAS TURNED OFF TWICE WHILE IDLING, IT WOULD NOT RESTART UNTIL ENGINE COOLED DOWN. THEN WAS ABLE TO START ENGINE. MECHANICS HAVE NOT BEEN ABLE TO DETECT PROBLEM EVEN WHEN VEHICLE WAS SCANNED FOR CODES. HAVE TAKEN IT TO DIFFERENT AUTOMOTIVE SERVICE SHOPS INCLUDING DEALERSHIPS AND NO ONE CAN FIND THE PROBLEM BECAUSE THEY STATE IT IS INTERMITTENT. AIR TEMPERATURE OUTSIDE OF VEHICLE SEEMS TO BE A KEY FACTOR WITH CAR STALLING WHEN TEMPERATURE VERY HOT. THE CAR HAS NEVER OVERHEATED WHEN THIS OCCURS.
