2004 GMC Yukon Denali AWD/122000 miles. All stock.
So problem with Yukon:
-(Year ago or so..)Starter would turn over engine but engine wouldn't start. Only happened once in a while..
-Fast forward a few months an a half dozen times of waiting what turned out to be 10 minutes or more and doing research online I learn about GM's pass lock system, believe this has the pass lock 2.
-Don't have owners manual but have a .pdf from online somewhere for reference.
-The symbol on the dash with the car and a padlock will illuminate constantly, or sometimes blink, either way starter will turn over engine all day or til it burnt out if I held the key. Will wait approx. 10 minutes. This happened a dozen more times in the past year, then sometimes it would take 3 times waiting 10 minutes each. The passlock light would turn off after 10 minutes or so and I'd try again just to let it turn back on.
-Recently, through the past month or so, the battery has been dying. Weird though I'd drive it around all day, then leaving Target at night and the battery gauge on the dash reads about 9 or 10 volts and the car won't start, get it jumped but it doesn't start even after waiting a few minutes. I realize the passlock light is on, it goes off after 10 minutesish, but voltage is still low and won't start. Get someone to help me jump it and it works.
So in 20 minutes of being in the store after starting several times all day without issue it dies.
-Performed a draw test with my meter and found the radio and radio amp fuse were drawing too much so I've since pulled those fuses and have been riding around with no radio for a couple weeks. Batter is still dying.
-Performed a battery load test, was a little low but nothing to worry about, also hooked battery up to a charge on 2amp over night(18hrs). Tested with meter later the next day and it read well, about 13.6ish.
-Also, the DIC has displayed several times but only when batter wouldn't start car 'service system stability' and 'service brake system'. Once battery was jumped or charged the warnings never showed so I'm hoping/thinking these were triggered from nothing more than low voltage.
-Sorry for length, to recap:
-Passlock light comes on and it has left my wife and I stranded in parking lots with our young son for upwards of an hour while waiting out the light and getting a jump.
-Battery dying and triggered 2 warnings on the DIC, sometimes they accompany the passlock light other times they don't.
I really just want to hit the guy who designed the passlock system and the guy who decided not to put a recall or TSB out about this, at least I haven't seen anything.
I've read many other posts in the past but haven't seen these 2 things together. Maybe they are related maybe not.
Can someone help me from losing any more of my hair?
