2013 Yukon XL Denali electrical issue ?
A couple weeks ago while driving home all my lights flickered and dash screen re-started, but drove remainder 10 miles fine. A few days later same thing happened again. Now it is happening every two or three days on my 30 mile drive to or from work. I've tried researching for a known issue with little luck. I've added a new ground strap from motor to firewall, and another from battery to body. Replaced the five year old battery which was very swollen on both sides. Only message that has ever come on dash is to check trailer wiring system, which i have done. I am asking if anyone on here has any suggestions ?
