Yukon LX 6.2L

  • Automatic transmission
  • 130,000 miles

2008 GMC Yukon Denil AWD 6.2L. Some days volt gauge will jump head light dim & brightens, remote doesn't work sometimes, some times when starting no power, while driving cuts off can not restart, pop hood power came back on. All light started going crazy, no message is displayed & no check engine light. New battery. Alternator check good. Terminal are tight n clean, never jump off vehicle battery strong just all power quits time to time nothing will work or come on. But once power comes back on everything works as should.

Update from Mar 13, 2019: 2008 gmc yukon denali AWD 6.2L one minunit nothing wrong next no power to any thing key fob will not work either. Several time lost power suv shut off while driving one vheicle when in a ditch to keep from. Smashing rear of vehicle. ITS THE GROUND WIRE BATTERY TO ENGINE BLOCK AND GROUND WIRE ENGINE BLOCK TO FIREWALL.. WHEN IT ACT UP TAKE A WIRE TOUCH NEG BATTERY POST ONE END OTHER END TO ENGINE BLOCK SOLVED EVERYTHING. Went to local parthouse store about a negative wire cable typically hooks up to a ridding mower bolt on one to battery post to from of engine block other wire fire wall to side of alternator there's a bolt sticking out of the side of the mountain bracket.
