NHTSA ODI 11731310

My engine starting making a knocking/ticking noise out of no where. I was traveling alone on the highway so I stopped to check it. I got to a gas station and google searched it and it came up that the LS 6.2 engine that is in my vehicle was recalled on other models because of this issue. I did have a mechanic look at it as well and he agreed it is that same issue that was recalled in other models.

My truck lost power while I was driving. Took to a shop and they found that a had a bad lifter. I have all of my service records from the GMC dealership where I had my vehicle serviced on a regular basis.

I started noticing issues with my transmission around 55,000 miles on it. It first started with no noticing that it wouldn’t gear down when it needed to, and then when it finally did gear down, it would really jerk the vehicle. I started calling GMC then and questioning and putting in a claim. Just went back-and-forth four months. Now it was getting worse to where I could feel the transmission slipping it wouldn’t kick into upper gear or lower gear. Again, I was still calling GMC and reporting these issues. I was told to take it and have a transmission oil change, which I did costing me $300. I still noticed this problem and I continue to call. I kept being told that they would have somebody call me back which nobody ever called me back to find out specifics. I took it to a GMC garage have them put it on a machine, and I was told that it needed a new transmission and this wasn’t something GMC was covering. This new transmission cost me $6200 and was done on 1/5/25. Please remember this vehicle only had 64,000 miles on it, which is absolutely ridiculous to need a transmission at this mileage. I again had called in January 2025 reporting this and was told someone would call me back and never heard from them.

My vehicle started making a knocking sound and eventually died on me. I barely made it to a repair shop to check out my vehicle, but had to get it towed back to my home from the repair shop after they told me my engine failed. This happened around 118,000 mileage. I found out that this issue is very common and needs to be addressed for this year and model vehicle. It could have ended very badly for me as I was on the interstate when it happened. Now, my vehicle is sitting and I am unable to use it. Engine would cost me over $12k for cost and repairs.

I bought the vehicle in October 2024 ever since then I have been trouble with the differential, the automatic starter doesn't start the vehicle unless you are at least one feet away from the vehicle. I drove to work when I got off and got in my vehicle my check engine light was on. The vehicle was saying there was an issue with the battery, antilock braking system. I bought an extended warranty up to 150,000, I currently have 63,400 on my vehicle. Empire Buick GMC of White Plains has not been honoring my warrantee, I had to rent a car to get back and forth to work because of fear of riding the NYC subway.

Not even 100,000 miles on it and the engine blew. Started with a lifter issue. Everyone I talk to with Yukons and GMC in general say it’s a problem. Just a search on the internet shows that they all have this issue… a well maintained car should not have this issue and it’s clearly a GMC issue and it needs to be fixed. The repair shop can’t even order me a new engine due to this being a real problem all over with GMC.

I was taking my client to school. I stopped at the stop sign. When I pushed gas pedal to go, my truck did not go, it strained did a big jerk then went. The next morning it did the same thing & later on that day, it did it again. Two days later I had to stop at red light. When the light turned green I pressed the gas pedal & nothing. It did not go at all. I turned the ignition off and back on twice & put it in drive still did not go but was slowly going backwards. A by-stander stopped to assist me getting my truck out of traffic.

Lifters failed 2nd time at 130k miles. Driving on highway at 70mph cruise and engine went to limp mode. Multiple repairs. $5,000. Dealer sold it to me in 2020 with 80k miles and did not disclose prior lifter replacement. I know they did something as a head bolt is missing.

Tail lights went out. Lifters have been replaced TWICE! While stopped at red light, at take off the vehicles lunges forward. At low speed the vehicle will down shift on it’s own. 80k miles Recently while headed to work, the torque converter went out. 126k This is suppose to be a luxury vehicle and cost entirely to much to be a POS. I honestly thought I had a lemon but it seems to be a reoccurring issue in the entire fleet.

1.)Rear Brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2.)The suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3.) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4.) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

Lifters

The engine light has come on spuradically for the last 1.5 years and has been consistently on since May of 2023. This starting approx. 95,000 miles. During this time after starting the Yukon it is chuggy and missing, as I drive off it jerks and darts forward. Seems to be when I stop and start to go this happens, again engine light is always on...sometimes flashing. Starting 9/19/23 (106,000 miles) when slowing down to turn into a parking lot the engine revved high, no movement with the touch of the gas pedal and suddenly takes off with a jerk and a squeal of the tires. VERY SCARY. Since then I have experienced this DAILY, at least once a day. So far it is when I am going slow, either taking off and accelerating or slowing down. The engine and RPMS rev up and go high with no way of moving when touching the gas pedal then suddenly jerks and takes off with the tires squealing. I am also experiencing the transmission shifting VERY hard, mainly when slowing down. I am feeling very timid and scared to drive this vehicle...this is a seriously dangerous situation and can cause a serious accident or life! I believe this fits into the description of the GM Class Action Lawsuit filed over transmission problems. When I previously talked to the dealership they kept saying that there was no recall for the problems and to bring it in. I am not going to continue to get things fixed that do not fix this problem, as I have already. I know of a friend who has the same vehicle/year only a Tahoe and is experiencing the same problem and had work done at a dealership with no fix for their issue neither. Something has to happen with this problem from GM! The contact stated the issue has gotten worse pushing down the gas pedal rendering the vehicle immobile, then all of a sudden it jerks and shifts into gear jolting the vehicle forward.
