NHTSA Complaint #11702865 — 2017 GMC YUKON XL

On July 3, 2025 we were traveling on a 4 lane at 55mph. Without any prior symptoms, the vehicle began to shake violently. It shook so hard that the skid warning light simultaneously came on. It was followed by the check engine light. The oil pressure guage started bouncing around. We stopped driving the vehicle and had it towed to VanYork GMC dealer in Asheboro, NC on this same day. (Invoice attached) VanYork GMC determined that cyclinder 5 was misfiring. We paid to have them repair it, and we began driving the vehicle again. (invoice attached) On or about August 1, 2025 we were traveling on an interstate at 70mph. Without any forewarning, the vehicle began to violently shake. Just as before, the skid warning light simultaneously came on, followed by the check engine light came on, and then the oil pressure guage started bouncing around. As there was heavy traffic on the interstate, the failure created a very dangerous situation for us as we tried to maintain our lane, and stay in control of the vehicle until which time we were able to safely maneuver to the side of the road. The vehicle was again towed to Vann York GMC in Asheboro, NC. (invoice attached) On December 3, 2025 we received a call from VannYork GMC saying that the vehicle repairs were complete. It had been in their repair shop for 4 months. This repair began with lifter and camshaft replacement. When this repair was unsuccessful, they decided that the vehicle needed a 'new' rebuilt engine. Since GMC has not offered any assistance with the expense of this new re-built engine, we will have to satisfy the $12,000 bill when we pick it up. After experiencing two very dangerous episodes, we are happy that we did not wreck, but certainly, this not the situation we expected from a high-end vehicle with only 76,169 miles on it.
