So 2018 Yukon Denali XL with 58k. Moms taxi to karate 2-3 times a week, so tailgate gets a workout with all their gear and groceries etc.
so it works fine with either button or key fob. The new issue is as it closes its slamming shut the last couple inches.
Anyone deal with this? It’s in the 60’s so not cold and it goes up and mostly down at normal speed.
Could it be just an adjustment? Support strut starting to die? Any ideas are welcome.
