2022 GMC Yukon

My engine has failed twice. I am now on my third engine. The vehicle stalled while driving on a highway, was in the shop for nearly 3 months and was "fixed" with same 6.2 engine. Eight months later it stalled again was in the shop for 2 months with a new engine. I was informed that they still don't know the issue and they just put the same type of engine. A bandaid was placed in my vehicle and I'm suppose to feel safe in it.

This vehicle has been towed into GMC service 3 times to date. #1. 2/2024 (mil 22,662) would not start, low voltage msg, replaced battery. #2. 4/2026 (mil 57,854) vehicle went into N on its own while I was driving down the road, msg on dash "function not available", I stopped and the engine died & would not restart, no engagement from starter motor, found P0615 present, found blown fuse on battery distribution fuse block, replaced. #3. 7/2026 (mil 63,041) vehicle went into N on its own while I was driving down interstate, msg on dash "function not available", I stopped, the engine died and would not restart, found main battery fuse blown, engine seized, found spun rod bearing full of metal debris, replaced engine, radiator, cooler lines, seals, gaskets, bolts, & fluids. My safety was at risk as I was driving down a highway and the interstate 2 of the times the vehicle put itself in N. The problem has been confirmed by the dealer. The vehicle has been inspected by the dealer's service dept. Prior to these incidents I did not notice any symptoms that would have alerted me of what was to come. **This report is referring to my latest incident which was engine seizure. *Two recalls have been performed, #1. 5/2025 "reprogrammed serial data module" & #2. 11/2025 "engine loss of propulsion recall", replaced oil with 0W-40 & "ECM software update recall", replaced ECM with SPS.

Monday, March 30, 2026 my GMC Yukon Denali had already had the recall pico test and was told it passed on September 2025 six months later March 30, 2026, driving to pick up my wife from work a tapping sound coming from the engine started and about a mile down the road from when I first heard the tapping the engine started juttering and the noise got louder like a clunking sound. I had to pull off the road into a gas station and use the OnStar to get assistance the vehicle was towed to a local San Antonio dealership Cavender Buick West they gave me a loaner vehicle the next morning and the day after that Wednesday I was informed that yes they confirmed the engine will have to get replaced so now I am waiting for that. I was told by the dealer it could take up to two months for them to receive a replacement engine and once they receive the engine, it can take roughly for maybe five days for turnaround. I inquired whether the replacement engine isn’t upgraded engine or is it the same engine that has all the problems I haven’t received an answer for that yet. I am awaiting that answer from my service advisor. He said he is looking into that.

While driving my 2022 GMC Yukon with approximately 150,000 miles, the engine suddenly began running rough and I immediately pulled over. The vehicle had to be towed to the dealership. The dealer diagnosed a collapsed lifter and camshaft damage and recommended full engine replacement at a cost of about $9,450. The vehicle had no prior engine issues and most miles are highway miles. Sudden engine failure while driving creates a potential safety hazard due to loss of power. I am reporting this because I understand there are ongoing investigations into GM V8 engine failures and I believe this failure may be related.

Filling this vehicle with diesel fuel per the manufacturer's user manual instructions results in a fuel leak centered between the rear wheels from somewhere at the top of the fuel tank. This has occurred during almost all fuel fill-up stops over the last year. The local dealer could not find the problem. A similar issue occurred with the 2021 diesel Yukon which has the same fuel tank as verified by part number. This was quietly remedied under warranty by the manufacturer.

I’m filing this complaint regarding my 2022 GMC Yukon Denali (VIN: [XXX] , MSRP ~$76,805) with an unresolved L87 engine recall. I made an appointment at my local GMC dealership on 5/8/25 specifically for the L87 recall. Upon arrival, staff only documented the Serial Data Gateway Module recall, which I hadn’t even known about. When I mentioned the 6.2L engine, I was asked if I was “sure.” I believe I was treated dismissively because I’m a woman. After pushing back, staff pulled up the bulletin, confirmed my engine needed replacement, and told me to “drive it until it blows up or there’s a fix, whichever comes first.” The L87 was only added to my receipt after I insisted—it was falsely listed as an “added operation,” though it was the reason I came in. I sent a certified letter to GM on 5/12/25 (signed for on 5/15/25) confirming the date I tendered the vehicle. Both GM and the dealer were fully aware the 60-day federal repair window had begun. It is now well past that deadline, and the L87 recall remains unresolved. Compounding the issue, the AC failed on [XXX], and the vehicle has been parked since early June due to extreme KY heat, making it unsafe to drive my children. I rely on this vehicle for daily commuting—driving ~100 miles/day for work—and it is also the only vehicle we own capable of towing our family boat, which has now sat unused all summer. I am currently paying $1,000/mo for the Yukon, $600/mo for the boat, and $200/mo for insurance—$1,800/month in preventable financial losses caused by GM’s failure to act. No repair has been offered. No loaner vehicle has been provided. No response has been received. I believe I was misled and discriminated against at the dealership, and I am now financially burdened and without a safe, reliable vehicle. This situation qualifies under the National Traffic and Motor Vehicle Safety Act for repurchase, compensation, or forced resolution. I am requesting a formal investigation and full remedy.

On the morning of Thursday, [XXX], our 2022 Yukon Denali departed from West Richland, WA with the intent to arrive in Spokane, WA. After a short stop in Ritzville, WA around [XXX] local time, we entered the freeway ([XXX] to Spokane, WA) and attempted to pass a semi-truck. The vehicle got to approximately 60mph and then began to rev without any propulsion to increase speed. The vehicle shut off completely and stated that we were to put the car in neutral and attempt to restart. While going 50-60mph, we shifted into neutral and attempted to restart without any success. While the situation was extremely dangerous give the traffic (semi-truck on the right and an approaching vehicle directly behind us), we slowed the vehicle and maneuvered to the shoulder where we stopped the vehicle. The vehicle would not start so we leverage the OnStar system to call a tow truck. Unfortunately, there was no ride available being 1-2 miles outside of Ritzville, WA where transportation services do not exist. We requested the help of WA state troopers who picked up 7 of us (4 separate trips) on the side of the highway. The vehicle was towed to Spokane, WA and we were left to fend for ourselves to get to Spokane. The vehicle is in the shop and we are told based on the codes achieved that it is a full engine failure.

After only 47,000 the Yukon started with hard starts and triggering a check engine light. Owner suggested fuel issues, the dealership suggested a bad wire. They adjust the "bare wire", and mentioned that the fuel pumps on these vehicles have issues and they would order one- but give them a holler when we have additional problems. The Yukon continued to hard start, evolving into stalling when started. The dealership was alerted but due to lack of engine codes being stored the dealership couldn't help us. Eventually when driving 57mph, the Yukon cut engine on a busy route, driver was able to get the Yukon to the shoulder and attempted restart- the Yukon was dead. AAA attempted to battery jump the Yukon without success. We were without our Yukon for 8 weeks, being placed in random trucks that couldn't support our family size. Upstate Chevy of Attica was not help in the process. We did contact GM directly and received a case number 9-14907008493. The engine was replaced. The Yukon still doesn't seem to be 100%, with some slow to starts. We are asking for compensation toward another GM full size SUV. We are GM friends and family and have purchased several vehicles over the years. We'd like to trade our suv now for a new 2025 without engine issues- but since our Yukon was gutted, that is now noted on a carfax which devalues our trade.

After the vehicle was serviced with a fuel injection cleaning and an oil change (by a GM dealership), the vehicle lost about 5 miles per gallon while driving and has not improved since. . I brought the vehicle back to the same dealership and complained. Another fuel injection cleaning was performed, but it did not help. It has been about 3 months and nothing has improved. I use 93 octane, TopTier gasoline.
