“Our 2015 Yukon Xl denali caught fire in the engine compartment while waiting at stop light on sat, with my wife and children inside. It was a hot day, over 95 degrees, and we were turning left across traffic when we realized the smell and smoke was coming from our vehicle. Smoke whiffed from under the hood and noxious fumes filled the passenger compartment, scaring me and my family. We finished the turn and immediately pulled over, shutoff the truck, and all escaped fearing it would burst into flames. Whatever was burning appeared to stop once the ignition was off. …”
NHTSA complaint #11340928, filed 2020-07, 37,500 miles“I purchased my vehicle october 31'st 2019 from a local dealership. The milage was about 74k miles. I have only had this vehicle for a few months. My concern is the following. While driving, at least 7 to ten times the vehicle completely stalls. In other words it completely stops. The steering wheel locks. All power is lost. No lights no nothing. This has happened at intersections, it has happened when turning left, it has happened when turning right. It happens when we are yielding. Sometimes the dash starts to flicker and also the console. Sometimes like today without any warnings. …”
NHTSA complaint #11309700, filed 2020-02, 86 miles“Anytime the vehicle is running the fumes from the exhaust make me and my kids feel nauseous and giving headaches just from walking to/around the truck to get in. We are taking this truck to the dealer on monday. Being the 3rd dealer we have taken it to in the past year. Have had many other issues out of this vehicle and just cant seem to get them all fixed. For such a pricey vehicle you wouldnt think there would be this many problems. The lift gate is popping not wanting to open or shuts on you as you walk under it. The window appliques are just slowly flying off 1 by 1. …”
