The 2003 Yukon Denali has eight current recalls related to issues with a brake valve, seat belt routing that may not fit the passenger properly, and the possibility for a fuel leak when certain aftermarket fuel filters are used, which presents a fire hazard.
If a particular model year of the GMC Yukon Denali that you’re interested in is affected by a recall, you’ll want to make sure the problem was addressed before you decide to buy it. And if a new one were to be issued after you already owned the vehicle, you could get the problem repaired at no cost.
