| Suspension problems |
Vehicle shifted into neutral while driving down the highway, extremely dangerous. Would not shift into gear and could not accelerate. Was able to pull over and the vehicle would not restart. Had to have the vehicle towed to a dealership. Dealership found a blown fuse, problem happened again twice and the dealer could not find the problem. This was July 28th, 2026. On August 20th, while in cruise control, slight ringing noise began, then a loud thump, then a loss of oil pressure. Unable to do anything other than pull over on an interstate with my family. Again, very dangerous. The vehicle would not restart and could not be shifted out of park. Had to have the vehicle towed again. Have also had at least 8 recalls on the vehicle. Unbelievably dangerous situations with my family, aside from inconvenient and expensive.
My 2023 GMC Yukon denali xl, used as a commercial vehicle for my business, experienced sudden and complete engine failure at approximately 70,000 miles with no prior warning. No check engine light, no unusual noise, and no other symptoms. The vehicle had previously been inspected/serviced under gm safety recall 25v-274 (l87 engine loss of propulsion) and had been deemed safe prior to this failure. The failure occurred while driving on a two-lane road in durango, CO. The vehicle lost all propulsion and came to a stop in the roadway, blocking the lane of travel and forcing other vehicles to cross into the oncoming traffic lane to go around the disabled vehicle. This created a serious and immediate hazard to myself and to oncoming traffic. The vehicle was not driveable and had to be towed. The dealer confirmed catastrophic engine failure requiring a complete engine replacement. After the engine replacement, the morehart murphy GMC dealership in durango also failed to properly recalibrate vehicle sensors. They did not reinstall certain suspension components that had been removed for the engine replacement, requiring multiple additional dealership visits to resolve along with recalibration of the air ride suspension. After the replacement I was getting messages that the vehicle was "too low to drive with caution" and "reduced acceleration drive with care. " this vehicle failure occurred during our peak season (June 10-July 2). The vehicle being out of service, I was required to rent a replacement vehicle at my own expense because gm did not provide a loaner vehicle. I estimate loss revenue at $1k/day. When I attempted to raise this issue with gm directly, their response was to submit letter to a p. O. Box, with no other means of resolution or contact offered. Given that this vehicle had already undergone the recall remedy and was represented as safe, this incident is relevant to NHTSA's ongoing investigation into post-recall l87 engine failures (recall query rq26001).
