Long crank time on hot restart – GM products
GM has issued a technical service bulletin (TSB) 06-06-04-049 to address long crank time on hot restart, starter keeps cranking, starter does not stop after releasing key. The TSB applies to the following vehicles:
2005-2006 Buick Rendezvous, Terraza
2004-2006 Chevrolet Malibu, Malibu Maxx
2005-2006 Chevrolet Uplander
2005-2006 Pontiac G6, Montana SV6

NOTE: This bulletin only applies to vehicles with Delphi EGR valves. Vehicles manufacture red with Seimens EGR valves already have the latest calibration.
If you own one of these vehicles and experience intermittent extended crank times on hot engine restart and the starter motor does keeps cranking after engine start the problem is a software glitch. You must have the computer updated with the latest calibration software.
