   Total Engine failure. This is the second time. The vehicle had under 2000 miles when the first engine failure happened and left us sitting on the Turnpike. Very unsafe!! We were assured we received a new "upgraded" engine only to find out GM decided to roll the dice with our lives and the lives of our family (grandchildren) and put another bad engine in our vehicle. I will never feel safe with this vehicle or that they are putting in "new" parts.

   Computer screen is black 90% of the time. During this vehicle has no back up cameras, no control of air conditioning, no control of heat or defrost, no heated seats, no mapping system, no vehicle safety display of tire pressure, oil life, brake life, no ability to control radio. These features cannot be turned on with manual push buttons as they are controlled thru the computer screen. 2 complaints to GMC have resulted in them stating they have no fix as it is a software issue. They have refused dealer request to replace the computer. As a [XXX] with health issues, the vehicle has sat parked due to no air conditioning. With NNY winter weather approaching, vehicle is unsafe without heat or defrost. Vehicle was purchased on XXX and problem was immediate. I find it amazing that GMC has had 9 months to resolve and they do not have a single competent software engineer! GMC case #XXX issued on XXX6. Buy back denied as GMC states it does not meet NYS Lemon law because vehicle is drivable. I disagree as I feel it is unsafe. GMC case # XXX opened on XXX. On XXX I was notified by phone from GMC that Tech case was being closed as they have no way of repairing. Again, requested new computer but was immediately denied as they continue to use software excuse. GMC rep. stated it is my responsibility to periodically contact a GMC dealership to see if a repair is available. All GMC correspondence has been by phone as they will not put anything in writing. Meanwhile I have an $ 80,000 vehicle that I feel is unsafe heading into snow and cold. NYS AG complaint was a waste of time as they determined I should hire an attorney and take GMC to court. I do not want to risk my safety or anyone else on the road. Common sense tells me if my home computer had a blank screen, I would have to replace it! On XXX I left vehicle at NYE GMC in [XXX] for 5 days. They confirmed there is no fix, they confirmed screen is black majority of the time.

   The shark fin antenna has a plastic cover that is only held on by 4 plastic clips. Hi winds or car wash can compromise the cover by breaking at least two of the plastic clips allowing air to get underneath the cover and then the cover falls off. I consider this a safety issue due to the fact that if your on a highway and it comes off it can crash thru another vehicle’s windshield causing a collision with other vehicles or cause serious injury to the occupants of the vehicle it strikes. I looked online and it seems to be happening to numerous GM vehicles with it falling off.

   Filing as a proactive data point for the ongoing NHTSA Office of Defects Investigation Engineering Analysis (EA26005) regarding GM 6.2L L87 engine failures. Vehicle is a 2026 GMC Yukon XL AT4 equipped with the 6.2L V8 and 10-speed transmission. The vehicle currently has approximately 2,800 miles and operates perfectly with no mechanical symptoms, ticking, or loss of propulsion. As an active preventive measure against internal component contamination, early engine oil changes were performed at 700 miles and 1,700 miles by a certified franchise dealer (Alpine Buick GMC). The engine continues to use the factory-specified 0W-20 oil viscosity. A magnetic oil drain plug has been installed to monitor for premature ferrous bearing and crankshaft debris at future service intervals. This report is submitted to ensure 2026 model year data running 0W-20 oil is officially documented within the federal investigation scope.

   Engine blew at 8,762 miles in the middle of the night with 3 small kids in the car. Currently 41 days waiting for a new engine. We were driving and it started making a clapping sound like something was caught underneath. We had to drive a could miles to find a safe place to pull over. If we increased speed, the clapping increased and it slowed when we slowed. Hauled it to the local dealership and they said it was the engine. The dealership it was purchased at says the same thing. There was no warning. After a couple of miles of the clicking/clamping sound, the car started to shake and then died. There were no warnings or light on the dash of any signs of distress until it died. It was a couple of miles before we even had a safe place to pull over on the side of the highway. Going 70mph on a highway that is posted to be 70mph with 3 kids in the car, in the middle of the night, put my family’s life in danger along with other cars behind us. Clearly safety and quality isn’t GM’s top priority. This is our 5th Yukon. Our 13th General Motors vehicle. To say we are disappointed is an understatement when we have been devoted to GM for over a decade.

    This is a follow-up to my previous complaint - 11716917. My second engine, which was installed after my first engine failed after approximately 5,000 miles, also failed. It failed after approximately 5,200 miles on it. I picked up the vehicle after the first engine replacement on 2/19/26 and the second engine failed on 5/18/26. It failed as I was driving to work - I was able to exit the highway and pull into a parking lot. From there I had the vehicle towed to a dealership and they confirmed that the engine had failed and needed a total replacement. This is a 2026 Yukon XL Denali Ultimate with the 6.2 L87 engine. I want to make sure the NHTSA is aware that I’ve now had two complete engine failures and am on my third. I have no confidence in the vehicle and have no reason to believe that my third engine will last. GM has refused to do anything about this vis-a-vis extending my warranty or replacing my vehicle or buying it back.

    9 months into ownership, with 24,000 miles I had complete engine failure pulling into an intersection. Slamming into park while moving and shutting down. This is a known issue with the GM 6.2 liter engines but I specifically waited to order a 2026 as this was far outside the recall window GM had in place for this known issue and was led to believe the issue was fixed going forward. The car was towed to a GM dealer and sat for 39 days for a complete engine replacement. Now, a week after it has been returned it has sputtered and shut off as I am coming to a stop requiring a restart, not unlike stalling a manual transmission car. I think your agency needs to expand the investigation far further to include 2026 models. This is a 90,000 dollar brand new family hauler that I am supposed to trust my wife and kids are safe in. Now I cannot even trust it will safely take her through an intersection. Thank you for your time.

    Unknown brought my car in on July 24, 2026. They reported they do not know what is wrong with the engine, but stated GM is not letting them take it apart and told them to replace the engine. While the car was parked and during acceleration, my car was making a weird noise that got louder during acceleration. A few days prior to this happening, while driving on the highway, my car's emergency lights came on. I had to pull over to turn it off.

    The large central infotainment touchscreen (which controls climate control/AC, navigation/maps, audio, backup camera, and all primary vehicle functions) has repeatedly failed by going completely dark/blank without warning on my 2026 GMC Yukon Denali XL purchased new on [XXX]. The screen has gone dark on three separate occasions. First failure occurred prior to [XXX]; vehicle was taken to Champion GMC (7885 W Grand River Rd, Brighton, MI 48114) for repair and returned to me. The screen failed again shortly after. Second repair attempt was made on 06/22/2026; vehicle was returned and the screen failed again immediately. The vehicle is currently at Champion GMC for a third repair attempt as of 06/29/2026. Safety risk: Loss of the screen eliminates access to the backup/rearview camera, speedometer display, climate controls (heat and AC), navigation, and warning indicators — all while operating the vehicle. There is no warning, message, or dashboard indicator prior to each failure. The screen goes dark suddenly and without notice. The problem has been confirmed and repair attempted three times by Champion GMC. The vehicle has not been inspected by police or insurance representatives. The component is available for inspection upon request, as the vehicle is currently at the dealership INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    While operating the vehicle, I began to hear a metallic grinding noise originating from the center of the engine compartment. The sound was clearly audible within the cabin. Approximately one mile before the vehicle ultimately failed, the engine began to malfunction. As I slowed to a stoplight, the vehicle started to shake before shutting off abruptly and entering a coasting state. All electrical systems powered down and the vehicle would not restart. Shortly thereafter, heavy smoke began to emit both inside and outside the cabin, visibly coming from the hood and through the air vents. There was also a distinct burning odor. I attempted to restart the vehicle multiple times without success. The dashboard displayed the message: “conditions not suitable to shift.” Due to the vehicle becoming disabled on a curve and posing a safety hazard, I contacted the Sheriff’s Office for assistance to prevent a potential collision. Upon their arrival, it was noted that the engine compartment and hood area were exceptionally hot, particularly where the smoke was originating. The dealership has since confirmed they have also been unable to restart the vehicle. The vehicle has been inspected by the GMC dealer and is currently pending further evaluation by a GM-certified mechanic to determine the root cause. Prior to this incident, there were no warning lights, system messages, or other noticeable symptoms indicating an issue.

    On 3/14/26, on I-75 in Troy, Michigan at 70mph the vehicle, with 4000k miles on the odometer completely shut off. I pushed to restart the engine and it would not restart. My whole family was in the car and we were on a curve. I was able to coast to a flat shoulder. The vehicle would not restart or shift out of park. OnStar took seven hours to tow the vehicle. The dealer is installing a new L87 6.2L engine. I do not have the vehicle back yet. I received an economy car as a loaner. The dealer says GM will not extend the factory warranty despite the engine replacement. My family could have been easily killed.
