2023 GMC Yukon fuel system complaints
Page 2 of 2: complaints 11 to 16 of 16, newest first, as owners wrote them.
Driving on the highway and the engine completely shut down. The car was automatically placed into neutral and I coasted off the highway to a nearby gas station. The car was taken to the dealer, and they confirmed that it requires a brand new engine.
There is a safety recall but it has not yet been resolved, risking lives.
Recall for engine propulsion. Say that there is no remedy yet. I have read the warnings about what may happen and I am terrified to drive the vehicle. GM says to contact the dealer, dealer says to contact GM. No one wants to take initiative. If they cannot fix the car, they should buy the car go back so I can get something different. I have been driving an old car around because I’m am afraid of this one. Please help me.
My engine failed while I was driving & I had no warning. It was very scary & dangerous. Luckily I was in an area where I could get off the road quickly. It started skipping then lost power. I basically coasted off the road & had to call for help. It was making a bad knocking noise. This happened 2 weeks ago on April 16. It has been sitting at Glynn Smith.GMC dealership since. I was told by the service manager that the engine failed & I will need a new engine. the engines are on back order now. I fear they will replace it with the same problem. I see the recall this week but will changing the oil viscosity really fix it?? Doubtful. Someone is going to get killed or hurt from this problem. I do not want the same issue to happen with a new engine.
Vehicle shuts off and goes into neutral at highway speeds I am reaching out because it has happened to me three times in a seven month old vehicle and also five family members with Yukon Tahoe, Escalade same issue is very very dangerous please, I beg you take this very seriously and contact me so I could verify to you the other owners that I’ve had the same issue, but have not went far enough to make a complaint. I will prove it to you with other owners, same problem, where the vehicle just shuts off.
