ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
**Incident / vehicle info:** - **Year / Make / Model:** 2026 / GMC / Yukon (Elevation) - **Date incident began:** ~mid-March 2026 - **Odometer / mileage:** under 1,000 - **Component:** Back Over Prevention: Rearview Camera (and/or Electrical System / Visibility) - **Crash? Fire? Injuries? Deaths?** No / No / No / No - **Vehicle still owned:** Yes - **Dealer or manufacturer contacted?** Yes — servicing dealer Rick Hendrick City Chevrolet (Charlotte); GM Customer Care cases 101763052 and 102071761 - **Description (paste this — ~1,700 characters, under the ~2,000 limit):** My 2026 GMC Yukon Elevation experiences intermittent total failure of the center infotainment/display screen, beginning around mid-March 2026. The failure is heat-related and intermittent: the screen functions on cool days, and on hot days it fails the vast majority of the time, unpredictably, after the vehicle heat-soaks in the sun. When it fails, the entire screen goes dark and I lose the backup camera and surround-view cameras, all HVAC/climate controls, audio, navigation, and most secondary controls. Steering, brakes, and engine are unaffected. This creates two safety hazards. First, loss of the rearview camera image eliminates rear visibility when backing — the exact risk FMVSS 111 is intended to prevent — raising the chance of a backover crash. Second, loss of all climate control in extreme heat endangers occupants in North Carolina summer temperatures, and a blank, unresponsive screen is a driver distraction. Here's everything in copy-paste form for the NHTSA complaint. **VIN:** 1GKS2BKD1TR227930 **Incident / vehicle info:** - **Year / Make / Model:** 2026 / GMC / Yukon (Elevation) - **Date incident began:** ~mid-March 2026 - **Odometer / mileage:** under 1,000 - **Component:** Back Over Prevention: Rearview Camera (and/or Electrical System / Visibility) - **Crash?

ENGINE
On May 27, 2026, I was on my way home from work when I went to accelerate the vehicle and all the sudden it started shaking and the check engine light came on with the EBS. I was able to get the vehicle to a repair shop local the next day, who took the car apart. What was thought to be an easy fix of spark plugs and fuel injector, became even more after they put back together and the cylinder was still misfiring. After several hours of taking apart the engine, the mechanic determined that the hydraulic valve lifters had failed. This has been an ongoing issue with with the 5.8L V8. Due to a recall not being under the vin yet, i have now incured a $16k expense to add an engine to it after i purchased it in Nov of 25 at $97,000. This is a saftey issue and luckily no one was hurt when the car started shaking and couldn't go over a certain speed. I want this reviewed and looked at for possible reimbursement as there have been several other vehicles with the same known issue.

ENGINE
The engine began making a metallic knocking noise while at idle and very soon after began to make the same noise under acceleration. This noise sounded very much like the onset of rod bearing failure. The vehicle was driven straight home and parked. We called the dealership the next day and made a service appointment. As I drove the vehicle to the dealership, the engine noise became worse and was clattering very loudly as I pulled into the dealership parking lot. I pulled into a parking spot and let the engine idle with the transmission in Park while I was collecting some personal items when the engine stalled. I tried several times to start the engine but it would not crank. The dealership engine tech later confirmed that the engine was seized

ENGINE
I am filing a complaint regarding my 2021 GMC Yukon due to a serious engine failure involving the camshaft, lifters, and crankshaft. The vehicle began exhibiting engine ticking and knocking noises, rough idle, loss of power, and reduced performance. These symptoms progressively worsened and ultimately resulted in major engine damage. The vehicle was diagnosed with failed lifters and camshaft damage, which required extensive repairs. In addition, the crankshaft failed, resulting in catastrophic engine damage and making the vehicle unsafe to operate. These are critical engine components that should not fail prematurely under normal driving and maintenance conditions. The most serious concern is safety. The engine's loss of power and deteriorating performance created the risk of sudden failure while driving. A vehicle that loses power in traffic, while merging, crossing intersections, or traveling at highway speeds can create a dangerous situation and increase the risk of a crash. Occupants and other motorists could be placed at risk if the engine fails without warning. My vehicle has been properly maintained and serviced. Despite regular maintenance, these major engine components failed unexpectedly. I am aware that other owners of GMC and Chevrolet vehicles equipped with similar engines have reported comparable camshaft and lifter failures, suggesting a potential defect rather than an isolated incident. The failure resulted in significant repair costs, loss of vehicle use, and concerns about the long-term reliability and safety of the vehicle. I believe these engine failures may indicate a manufacturing or design defect affecting 2021 GMC Yukon vehicles. I respectfully request that NHTSA investigate camshaft, lifter, and crankshaft failures in the 2021 GMC Yukon and determine whether a safety-related defect exists that warrants corrective action or a recall.

The engine had a sudden loss of propulsion on the highway traveling at 70mph. It went into netural and I had to coast to the side. Power cycled and it started back up for 15 more miles, then did it again and would not go out of park. Towed to dealer. PICO L87 recall was completed prior to purchasing the vehicle. 300 miles after purchase, the engine locked up. Dealer confirmed its an L87 recall failure. Vehicle was inspected on 4/21/2026. I have been waiting on a motor for 7 weeks with no movement.

Post-Recall Low Oil Warning + Performance Issues on 2021 GMC Yukon Denali – Campaign 25V274000 Vehicle: 2021 GMC Yukon Denali, 6.2L V8 Recall: 25V274000 Owner: One owner since new (purchased 2021) I had recall campaign 25V274000 performed on my vehicle. This was the first low oil warning I have ever received since purchasing the SUV new in 2021. I have always followed the vehicle’s oil life monitor with no prior issues. The change oil light appeared at roughly 7,500 miles after the recall service (when I already had a service appointment scheduled). About one week later, the low oil warning came on. I had the vehicle towed to the dealership and did not drive it after the warning. Since the recall service, I have also experienced performance issues including noticeable stuttering that was really evident before I towed it in. The dealership initially agreed to a consumption test but later acted like it was not needed, said everything was fine, and were dismissive — blaming me for not following their sticker. I am concerned the recall remedy is not fully effective. Please investigate this matter. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
During normal driving conditions the vehicle had set code P18A1 in the ECM. Code set due to an internal short in one of the solenoids in the valve body assembly. This caused the vehicle to display "Limp Mode" and lose reverse gear and propulsion over 45 mph. The vehicle was parked and towed to the dealership for evaluation. Upon inspection by a certified dealer technician, it was found that a solenoid had failed and required replacing. As part of the entire valve body, the solenoid is not a serviceable part. The dealership had to replaced the entire valve body assembly per repair guidelines. Per the GM and NHTSA websites, my 2022 GMC Yukon XLT with a 10-speed transmission is not included in the recalls listed below even though the symptoms are identical. General Motors publicly acknowledged the 10‑speed transmission valve body and solenoid defects, including internal electrical and hydraulic failures, through Safety Recalls, Special Coverage programs, and Technical Service Bulletins applicable to 2020– 2022 full‑size trucks and SUVs, including the GMC Yukon. My vehicle’s model year, transmission type, failure code (P18A1), and repair align with those documented GM conditions and should be included in this recall.

SERVICE BRAKES
Passenger brake Led Circuit board prematurely failed resulting in the entire assembly needing replacement. The assembly is $500 and higher. This is a safety issue and though there was a class action lawsuit, the light fails after 72000 miles which appears to be when GMC wont replace the part. $500 for a tail light replacement is a financial burden to be able to keep the car on the road. There is no warning when the light fails. Please consider a recall on the tail lights.

So the ultimate failure is from a catastrophically failed crankshaft journal thrust bearing. Which could be caused from one of two things: 1) The crankshaft thrust bearings they are putting in these motors are made with inferior materials, probably cheap Chinese crap or 2) The crankshaft end play tolerance was never set properly, giving the crankshaft the ability to move forward and backward in the engine more than it was designed to. Which will over time beat up on the thrust bearing until it fails. In either case it would result in the same progressive issue showing itself. It will start as a squeak here and there. Which, as the soft thrust bearing material is unable to hold the proper oil film thickness for lubrication, will spiral into more and more heat being sent into the adjacent components, plus the buildup of metal particles being sent through the entire engine oiling system. Which will then start killing connecting rod and crankshaft bearings one by one. If the engine survived to this point, it’s now a ticking time bomb. It is either going to just seize up and not run anymore or the exciting route would be a connecting rod breaks and makes a window sized hole in the side of the engine block.

Experiencing a stuck lifter in the DFM module. After doing some research, it appears there are a bunch of other people that are dealing with the same issue. The only recall was for the 6.2L engine but not the 5.3L. It appears that both engines are experiencing the exact same issue and GM hasn’t done anything to help with it.

The contact owns a 2019 GMC Yukon. The contact stated that after starting and exiting the vehicle to allow it to warm up, the contact later noticed that the vehicle had turned off. The vehicle was towed to a first mechanic, who was unable to restart the vehicle or determine the cause of the failure. The vehicle was towed to a second mechanic, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not repaired due to the cost. The dealer was contacted and provided an estimate for the repair, but the vehicle was not diagnosed or repaired. The contact stated that the dealer's estimate was higher than the mechanic's estimate. The manufacturer was notified of the failure and suggested purchasing a new vehicle. The failure mileage was approximately 170,000.
