Engine failure

After engine passed check for possible replacement because of recall, engine failed 5000 miles after. Even though I have a new engine now, there is no warranty coverage other than the lower part of the engine. I am already having misfire issues.

Catastrophic engine failure and sudden loss of propulsion on a highway after completing GM's OW-40 oil recall remedy.

PICO scope test #FDYZ295894391 on engine for recall #N252494003 engine , passed test. Drain oil filled with 0-40 replaced oil cap. Date 09/19/2025, mileage in 20142/mileage out 20142. Vehicle runs rough. Not stable at times. Vibration noise coming from the motor at times.

I was Driving down the interstate when the RPMS on my car increased and my car started to shutter. I went to get off the roadway and it put itself into neutral and lowered my speed. when i got On the shoulder it stalled and would not turn back on. I had To be towed. To this point, my car has been in the shop for over a week with no solution.

My vehicle had a previous engine recall that was “fixed” per the dealership recommendations. However, I succumbed to total engine failure last week at 70000 miles with my 2 little kids in the car on an interstate. My engine needs replaced.

I am reporting a severe, recurring, and life-threatening manufacturing defect involving a sudden, catastrophic loss of motive power at highway speeds on the interstate. This vehicle has suffered two identical valvetrain failures that placed my passengers and nearby motorists in extreme danger. Incident 1 (Approx. 40,000 miles): While traveling at high speed on the interstate, the vehicle violently shook, all engine warning lights flashed, and the engine suffered an immediate, near-total loss of propulsion. The vehicle was towed to an authorized GMC dealership, where technicians diagnosed a collapsed Dynamic Fuel Management (DFM) hydraulic lifter in Cylinder 3. The lifter bank was replaced under the factory powertrain warranty. Incident 2 (Approx. 77,000 miles): While driving at high speed on the interstate, the exact same vehicle behavior occurred. The engine suffered a sudden, total loss of power, and all dashboard warning lights illuminated simultaneously. Out of absolute necessity and to avoid a catastrophic high-speed collision on a dangerous stretch of highway, the severely crippled vehicle had to be forced through active interstate traffic without proper engine power all the way to my home. The vehicle has since been inspected by a GMC dealership, which has confirmed that the exact same Cylinder 3 lifter has failed a second time. The dealership and the GMC Regional Service Manager are currently refusing to honor the 24-month dealer-installed service parts warranty, demanding an out-of-pocket deposit of $5,000, and denying alternative transportation. GM's failure to permanently remediate this known, systemic valvetrain defect has twice left me navigating a failing vehicle through high-speed highway traffic, heavily compounding the safety risk.

Engine shut off with no warning, all electronics disabled and couldn't shift out of park. Was driving down the road at approximately 50mph, Yukon shifted itself into neutral. Vehicle previously complied with the 25V-274 recall and passed, was operating on the new oil that GM recommended.

Second engine sized at 87,834 miles. Third engine installed three weeks later.

On August 17th, 2026 while approaching a nature preserve entrance at approximately 1 mph, my 2023 GMC Yukon Denali Ultimate suddenly accelerated on its own, without the driver pressing the accelerator pedal, striking a split-rail fence and a tree. Airbags did not deploy. The front collision system didn't issue any alerts about the fence and tree. A GM software update had been installed a couple of days before this incident . In the weeks prior, the vehicle had also intermittently failed to hold side mirror position and periodically failed to deploy the power running boards. I request that GM and NHTSA investigate a possible link between the recent software update and an unintended acceleration event, potentially related to the adaptive cruise control or another driver-assist/body control module.

My vehicle was taken in as part of the 25v-274 recall. It passed and was given the new oil. It underwent a second oil change using the new oil and before the third oil change at around 46,000 miles the engine was having trouble. I took it in for the oil change and the engine issue. I have barely been told anything but from what I understand I have a camshaft issue and need new lifters. I haven't seen my car in 12 days and have received almost to no updates.

2023 Yukon XL AT4 with 67k miles suddenly had lifters fail. GM service said cam scored & metal debris all the way through to the pan, requiring total engine replacement. Vehicle was very well maintained with premium fluids and parts.

The contact owns a 2023 GMC Yukon XL. The contact stated that while driving approximately 30 MPH, the vehicle stalled. The vehicle failed to restart. The vehicle was towed to a dealer; however, the failure was not duplicated. The manufacturer was not notified of the failure. The failure mileage was 49,460.

Vehicle shifted into neutral while driving down the highway, extremely dangerous. Would not shift into gear and could not accelerate. Was able to pull over and the vehicle would not restart. Had to have the vehicle towed to a dealership. Dealership found a blown fuse, problem happened again twice and the dealer could not find the problem. This was July 28th, 2026. On August 20th, while in cruise control, slight ringing noise began, then a loud thump, then a loss of oil pressure. Unable to do anything other than pull over on an interstate with my family. Again, very dangerous. The vehicle would not restart and could not be shifted out of park. Had to have the vehicle towed again. Have also had at least 8 recalls on the vehicle. Unbelievably dangerous situations with my family, aside from inconvenient and expensive.

My 2023 GMC Yukon Denali XL, used as a commercial vehicle for my business, experienced sudden and complete engine failure at approximately 70,000 miles with no prior warning. No check engine light, no unusual noise, and no other symptoms. The vehicle had previously been inspected/serviced under GM Safety Recall 25V-274 (L87 Engine Loss of Propulsion) and had been deemed safe prior to this failure. The failure occurred while driving on a two-lane road in Durango, CO. The vehicle lost all propulsion and came to a stop in the roadway, blocking the lane of travel and forcing other vehicles to cross into the oncoming traffic lane to go around the disabled vehicle. This created a serious and immediate hazard to myself and to oncoming traffic. The vehicle was not driveable and had to be towed. The dealer confirmed catastrophic engine failure requiring a complete engine replacement. After the engine replacement, the Morehart Murphy GMC dealership in Durango also failed to properly recalibrate vehicle sensors. They did not reinstall certain suspension components that had been removed for the engine replacement, requiring multiple additional dealership visits to resolve along with recalibration of the air ride suspension. After the replacement I was getting messages that the vehicle was "too low to drive with caution" and "Reduced Acceleration Drive With Care." This vehicle failure occurred during our peak season (June 10-July 2). The vehicle being out of service, I was required to rent a replacement vehicle at my own expense because GM did not provide a loaner vehicle. I estimate loss revenue at $1k/day. When I attempted to raise this issue with GM directly, their response was to submit letter to a P.O. Box, with no other means of resolution or contact offered. Given that this vehicle had already undergone the recall remedy and was represented as safe, this incident is relevant to NHTSA's ongoing investigation into post-recall L87 engine failures (Recall Query RQ26001).

Our lifters in cylinder 3 were replaced after failing at 40,000 miles. The exact same lifters broke again at 77,000 miles.both events caused engine failure.

2023 GMC Yukon XL(6.2 liter engine).Engine has failed twice with the first incident being on the interstate and the engine seized without warning with only 38,000 miles. GMC replaced the engine and now the second engine has failed with only 80,000 miles on it. I am told there needs to be a third engine installed and the vehicle is only three years old. If an engine fails without warning this puts everyone in danger. My [XXX] son was in the car when the first engine failed. There is an obvious manufacturer's defect that needs to be addressed before innocent people are injured or killed. The vehicle is currently located at Darrell Waltrip GMC in Franklin, Tennessee. It is not drivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I got into my car to run some errands. As I drove away from my house, I made a left turn downhill. I noticed vehicles ahead, so I began to slow down. At that moment, I was driving between 20 and 25 mph. When I tried to brake, my brakes failed and started flashing a brake failure warning light. I kept pumping the brake pedal, and eventually, the car slowed down and came to a stop. I turned on my hazard lights, and immediately returned home. My nephew and I were both in the car. Our live flashed in front of us. Thankfully, there were no vehicles directly in front of me or pedestrians. This could have turned out to be the worst day of my life if anyone had been injured.

On my 2023 GMC Yukon, XL the infotainment screen freezes and you have no access to any vehicle information, including rearview camera. This issue appeared three months after I purchased a vehicle in 2023 and was taken to the dealership confirmed the issue, but said the resolution was to do a hard reset on the infotainment center. After driving the car for three years and taking the advice of the dealership and resetting the infotainment center every few weeks, the problem escalated and started freezing up at least once a week to eventually doing it every day and the heart reset wouldn’t always work the first time. Dealership eventually confirmed it was a defective radio module. This is a very large vehicle and the rearview camera is an essential necessity to avoid collision.
