While driving down the freeway, I received a warning that the charging system was not working and had a red battery light come on on the dash. I exited the freeway trying to get to a safe place, the dash and infotainment system begun to flash on and off. We heard a loud pop, smelt something burning, saw smoke coming into the cabin and then flames from under the hood near where the battery is located.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 GMC Yukon Denali Xl 1500 verdict →
