2003 Silverado

[pacampbell]

My 2003 Silverado would not start after a very cold New England night. The battery was dead and according to the clock it died around midnight. I had the truck jump started and it ran fine all day but the battery went dead again in the night. Does anyone know why this would happen to a new truck? The dealership is not helping they just want to recharge the battery but I think something else is going on.

Thanks for any help.

Try going in the truck and move the ignition switch back and forth with the key out. look at the (p r n d 1 2) if it comes on and off hten the switch needs to be replaced. it tis draining you batt. happened to my wife gm. also look at this gm bulletin on it, I know it says for trailblazers but it could be the same problem. hope this helps

thanks for you help on this. The dealer actually found something in the computer that was not turning off and discharging the battery. He reset the computer. That was on Saturday and so far so good.

Thanks - that was my first thought too. But it appears that there was something wrong on the computer, The dealer reset it and that appears to be the problem since the battery has not been discharging since.

Prob this recall:


2003 Recall--Possible Battery Drain Issue
Recall ID: 02066

Recall Description: BATTERY DRAIN

involved vehicles are certain:
2003 Chevrolet Silverado, Tahoe, Suburban; 2003 GMC Sierra, Yukon, Yukon XL; 2003 Cadillac Escalade, Escalade EXT, Escalade ESV
Equipped with Quadrasteer (NYS), Autoride (Z55), or Vehicle Stability Enhancement/StabiliTrak (JL4)

December, 2002
Dear General Motors Customer:

We want your experience owning your 2003 model year Chevrolet Silverado, Tahoe, and Suburban; 2003 model year GMC Sierra, Yukon, and Yukon XL; and 2003 model year Cadillac Escalade, Escalade EXT, and Escalade ESV vehicles equipped with Quadrasteer, Autoride, or Vehicle Stability Enhancement/StabiliTrack to be better than any other you've had ... which is why we're writing.

We have learned that your 2003 model year Chevrolet Silverado, Tahoe, and Suburban; 2003 model year GMC Sierra, Yukon, and Yukon XL; and 2003 model year Cadillac Escalade, Escalade EXT, and Escalade ESV vehicle may have the potential of exhibiting a battery drain condition. An anomaly in the operation of the steering wheel position sensor may keep the Body Control Module (BCM) from shutting down when the key is in the OFF position. The resultant 3.5 amp draw/load on the battery could possible discharge the battery to the point where the battery will not have sufficient amperage to start the vehicle.

What We Have Done
We've sent a new BCM calibration to your dealer so that your vehicle can be reprogrammed to ensure that the BCM shuts down when you turn the vehicle off. This service will be performed for you at no charge.

What You Should Do
We recommend that you contact your dealer to arrange a service date. If you have experienced this condition in the past and your battery was recharged or replaced, your vehicle will still need to be reprogrammed.

here are the VIN breakpoints to determine if your vehicle is possibly involved (contact your dealer or the customer assistance certain to determine for sure):
