The transmission shifts hard in low gears. I have done research, and it seems like this is a common problem that a vast amount of these vehicles have. I honestly think that this is has to be looked into for a recall. There is countless information on the web with videos, other owners, and transmission businesses explaining about it.

The Active Fuel Management (AFM) system malfunctioned causing not all engine cylinders to fire at critical times, thus causing a safety issue when the vehicle has insufficient power traveling at highway speed. The AFM is intended to transition from 8 cylinder power to 4 cylinder power to save fuel. However it malfunctioned so that it couldn't transition back from 4 cylinder power. The malfunction occurred while driving at highway speed, approximately 70 mph and towing a trailer. There were no warning messages or other symptoms prior to the failure. This malfunction necessitated removal and replacement of the engine. A certified mechanic completed the repair work.

Service Box appears indicating - "Trailer Brake System" with a loud BING, BING, BING Alert sound. It continues every few minutes... Please note: we aren't using a trailer... I have googled/youtube it and found that this is an issue with many owners. They indicate that the wire harness in between two of the body control modules is defective. It is known to have faulty wire connection. This is intermittent, goes for months and stops for months, and then starts up again. Starting the vehicle, while driving slow or fast, it doesn't matter.

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!

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.

As I was driving on the highway the check engine lights pops on and the engine starts stalling. The stability track light also came on and the truck was hard to maintain and drive. The truck has been maintained and serviced on a meticulous schedule. This is not the first major problem we have experienced with the truck, we had to do a full transmission replacement on the truck at an 118,000 miles mark. Me and my family have been the only drivers and owner of the vehicle and mostly on put highway miles. I am so frustrated and disappointed in the workmanship and quality of our vehicle.
