2007 Buick Rendezvous 6 cyl Front Wheel Drive Automatic 45000 miles
periodiclly the vehicle wont start. It appears the battery does not have enough power. It will start with a jump. The dealer tested for a voltage draw but could not find one. The battery and alternator have been replaced (less than 2 years ago). Dealer noticed some corrsion on the battery cable and cleaned that up, but problem happened 2 weeks later.
something is causing the vehicle to loose power when it sits overnight. It only happens periodically, and more often when it is a cold night.
dealer appears to be incompetent. I need your help.
Thank you for your consideration.
