LOUD NOISES STARTED UNDER THE CAR AND EVENTUALLY SHUT OFF IN MIDDLE OF THE INTERSTATE, THANK FULLY ANOTHER PERSON HELP US MOVE THE CAR TO THE SHOULDER AND NOTHING HAPPENED

The amount of rust that has been exposed is absolutely insane. My adjuster found the initial section of rust when we had the Yukon in for repairs from a storm. In the past 2 months, the rust has caused a massive hole underneath the rear passenger's side door and we have had no choice but to get it repaired. The initial estimate for this single repair is going to be over $3400. This rust easily could've broken down further and gotten into the brakes and other components right behind it as it sits very close to the wheel well. This is an absolutely dangerous issue and should be addressed.

My transmission is causing a lot of shaking and hard shifting and it's very detrimental to my physical and psychological health. I am a disabled veteran with back problems and every time my Yukon shakes (almost every single shift) it hurts my back and makes it difficult to do anything. This is a very, very common issue with this year make and model but nothing seems to be getting accomplished. GM needs to remedy these issues as a recall since most of us can't afford the $5000-$12000 that this type of repair is going to cost us and GM knows that this is an issue. I can't continue to risk my family's health and safety with this vehicle and it needs to be fixed immediately!

Started my 2015 Yukon XL, drove approximately 6 miles to get gas and was to head out onto the highway. After gassing up and starting engine it began to idle very rough with a shake going on and ticking noise. No previous signs of any issues. Slowly drove back to my house at 20 miles an hour and called Mandal GMC dealership. They suggested having it towed to them for inspection. Upon inspection they said the AFM/DOD #1 exhaust lifter was bad and needed replaced. They replaced all of Bank one lifters and said their was no damage to camshaft. Drove it that night after repairing it and everything seemed fine. They called the next morning and said when they started it up the ticking was back again. They then supposedly took off head cover and inspected the camshaft again and said it was damaged and I would need a new engine to the tune of $18,000.00. I purchase it in 2021 from them use and paid $33,000.00 and now still owe even more than the engine repair. I said it would cost more than the vehicle was worth and they had done $4,000.00 of repair that didn’t even get the issue fixed. I am a senior on Social Security and can not afford to continue to pay 20,000.00 for the loan and then another $18,000.00 for a faulty engine design that caused the problem in the first place. May have to join the thousands of others in the class action to get GM to not put out such untrustworthy engineering. Now $37,000.00 piece of Yard Sculpture !! The morning that it occurred was the first sign of flashing engine warning on dash.

The Yukon was driving normally and just lost power while driving 55mph on the highway. Then I got off the highway to pull over and check it out and the Yukon started shaking while running and in Park. The truck would not drive over 30mph without shaking and what sounds like misfiring.

While driving my check engine light came on. Engine was shaking and running awful. Smoke was coming from the tailpipe. Mechanic upon inspection informed me that a lifter had failed. Causing damage to the cylinder head. Also causing the fuel injectors to fail. The cylinder head had to be removed and sent to machine shop for repairs. Mechanic informed me that this is a very common failure for LS motors. Repair bill was $5300 for parts and labor.

In December 2024 took my GMC Yukon XL to a mechanic. They replaced the lifter in the driver side of the engine. 2500 miles later it is back in the shop for the same side. Now there is a bent rod. One of the lifter/Rod spots collapsed. The mechanic is in contact with the local GMC dealer to figure out what the next steps are. The recent symptoms had to have car towed back to Fairly reliable Bobs mechanic. Pictures were taken and sent to GMC. First time this happened I heard a Tic in the engine and took it straight to the mechanic. second time this happened. Engine light came on flashing, Trackton light came on, Lost power, there was a shimmy when slowing down and a shake at the stop. I will note the second time this happened below.
