I currently own a 2015 Yukon Denali XL which is loaded with a whole bunch of options. I bought it CPO with about 9000 miles on it. I purchased it from NC and went there to pick it up and drove it home to NYC from the dealer. I've had it about a year and so far put about 9000 miles on it. Last year the Wife to be and I took several trips with our new truck; 1st trip was from NYC to Canton, Ohio (Football HOF), then to Eerie, PA, then to Niagara Falls, NY and then back to NYC. That trip was a week long and I did all the driving. My Wife does not drive. Lol. 2nd trip was NYC to NC. Third trip was NYC to Orlando FL, then to North Charleston SC, then back to NYC. So far, I had had 0 issues with steering or buffering on any of the other issues mentioned. I did have an issue with the trim coming lose on the doors though. The Dealer ordered brand new trim for all doors and replaced it FOC and I've had no problems with it since. So, I have about 17000 miles on my truck and no major issues. Is it too early for those buffering or steering issues to surface? Should I be concerned? I'm really getting nervous reading some of your posts. I'm hoping to hold onto this truck at least 2 maybe 3 years before trade. Should I be concerned with these steering and buffering issues "popping" up???
