Have a Yukon, when I was driving battery light came on along with message "service battery charging

Asked by Jan 28, 2016 at 07:16 AM about the 2007 GMC Yukon 4WD

Question type: Maintenance & Repair

Have a Yukon, when I was driving battery light came on along with message "service battery charging system" then all lights/sensors come on such as ABS, airbag, tire pressure, Stabilitrak off, traction off, check engine light, etc.  Once all the lights come on, then the lights begin to dim followed by the truck dying.  I then have to charge for about 30 minutes and can drive about 15 miles before it does it again.   What could possibly be wrong with truck?  I've been told alternator, to needing an new electrical system, to a new battery.

This sounds like a bad alternator, what you are seeing are the side effects of low voltage and a computer trying to compensate without proper electrical supply. It is possible that the battery may survive if repaired right away but continue this and it will go bad. Go to a shop you trust and have the system throughly tested and replace the bad componets.
