Vehicle stopped working on a major road almost in the intersection in Lake Charles, Louisiana. The Vehicle is not able to be put in neutral to safely push it away to safer area. Had to be towed back to Texas at my expense of $400 and Service department says it is due to a blown 6.2l motor.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
The engine of my 2024 GMC Yukon Denali failed unexpectedly at 45 MPH, shutting off without warning and shifting into neutral. My wife, three passengers, and two dogs were in the vehicle, which coasted to a stop. After several attempts, it restarted, and the check engine light illuminated. Alpine Buick GMC confirmed catastrophic engine failure, requiring replacement of the engine, radiator, hoses, and other parts. The vehicle remains at the dealership, and the failed components are available for inspection. This sudden shutdown posed serious safety concerns. My wife lost control over acceleration and power steering, increasing the risk of an accident. Had this occurred on a highway or in traffic, the consequences could have been severe. This raises concerns about the engine’s reliability and potential risks to other drivers. Alpine Buick GMC confirmed the engine failure and the need for full replacement. I am the sixth customer awaiting this repair, indicating a broader issue. The estimated wait time for an engine is two weeks to three months, creating a significant disruption. Inspection by Manufacturer, Police, or Insurance The vehicle has been inspected by dealership technicians but not by GMC representatives, police, or insurance adjusters. I am open to further inspections to determine the cause and assess whether a recall or corrective action is necessary. No warning lights or symptoms appeared before the engine shut down. The check engine light illuminated only after restarting on the third attempt. The absence of prior alerts suggests a flaw in the vehicle’s diagnostic system. Expedited Engine Replacement – Given the safety risks, I request priority replacement. Investigation into Failure Cause – GMC should assess whether this is a manufacturing defect. Review of Similar Cases – If widespread, a recall or service bulletin may be necessary. Better Communication – Regular updates on repairs and GMC’s actions are needed. I expect prompt action to resolve

ENGINE
On Friday 2/21/25, while driving on the Interstate at Highway speeds, the dashboard said to idle the engine. The engine then stalled and thankfully I had enough speed and there was a shoulder available to pull off on. The dashboard then gave many messages including voltage, overheating, high oil temperature, idle engine, etc... I was unable to restart the vehicle on the side of the interstate. I was towed to the dealer who advised the engine would have to be replaced. This vehicle has a 6.2L gas engine with 39,223 (approx) miles.

Vehicle started jumping and switched into 4WD while reversing. There was no inclement weather or slipping to prompt this. Service 4WD warning had been showing intermittently for a week or two and service appointment had been scheduled. At service appointment, confirmed that 4WD switch was faulty and needed to be replaced.

ENGINE
As we were driving, without warning, the engine started to rumble and clank. We had to pull off the road in a neighborhood and have it towed to the dealership. Thankfully, we were driving on side/neighborhood roads at the time. If this would have happened on the highway it could have been very dangerous. They'll dealership said it was unsolvable and we needed to purchase an entirely new engine.

I was driving home from work at around 60 mph. Very sunddly their was a rattling metal sounds and then vehicle struggled to maintain speed. Before pulling off the highway at the next exit. On the exit ramp the engine turned off and would not turn back on. The vehicle was also stuck in neutral and not able to shift out of neutral for towing. There was no worning lamps or messages even after the noise and reduced power. Vehicle was towed to local dealership on Tuesday evening, as this was not scheduled it took them to diagnosis the issue as engine failure and recommending to replace the engine. The vehicle is a 6.2L GMC Yukon Denali with 23k miles. All service has been done at the dealer with no outstanding work prior to the engine failure. Where it gets more disappointing is the lack of information for time to fix. The replacement engine was ordered by the dealer on February 14th. As of February 28th they did not have any information....So i called GMC on that 1800 number listed on GM Document DCS6866 referencing customer satisfaction program N232413430. The first agent disconnected without filing a case. The second agent had to restart the process and was told that there was nothing they would do for 14 days after the case was opened before it would be elevated. When talking to the agent they denied any information related to the GM Customer Satisfaction Program or any knowledge of what seems to be a wide spread defect on 6.2L engines. The service and support for a $90k vehicle from, in fairness they have provided access to rental vehicle from a local auto shop. The vehicle is far smaller and different from our vehicle we purchased. The vehicle is still sitting at the dealership service center and is not functional until the engine is repalced.

The 6.2 L engine Yukon spun a bearing caused my car to shut down in the middle of the road barely got off the side. Lucky that we were not at highway speeds and nobody rear ended us. When I got to the dealership they did not care that this occurred and GMC customer care did not even acknowledge about the safety of us on the road when this occurred. At this point GMC nor the dealership has an ETA on replacement.

On February 21st when driving on the highway at highway speeds, the vehicle on its own shifted into neutral and I was forced to pull over onto side of the road before the vehicle allowed me to put back into gear of drive. Upon getting back onto the highway, I noticed and heard the sound of the motor very different and louder than normal, I immediately pulled over to the nearest exit to where the vehicle shut off on its own and did not allow me to control the vehicle. I was stranded at the exit where a number of other vehicles and 18 wheelers were trying to exit, I called the local PD, to come assist with traffic control and had to wait on tow truck to have vehicle towed home, then next day towed to local dealership. Received a phone call from dealership days later that the technicians were able to fire it up, but it immediately lost oil pressure and motor locked up, I am being told by the dealership that the motor will need to be replaced, it is covered under warranty BUT I am being given no timeline as to when it can be fixed.

While we were driving at a high speed all control of the vehicle shut down. There was absolutely no warning that this was going to happen to that anything in the vehicle was breaking down. We were able to get to the side of the road and the vehicle locked into N. From that point on the car did not work. After being looked at my GMC, they decided that it needs a new engine. It only has under 15K miles. We were told that some somehow pieces of metal were in the engine. Engines are currently on a national backorder and we have been without our vehicle for over 4 weeks. They have no expected date that this will be fixed.

Hello, I am writing this complaint because i bought this 2021 GMC Yukon new from King GMC in Loveland CO. The engine seized up on me while driving once turned off, i was able to get it going and now it has done it again but this time no luck getting it going, Maintenace has always been maintained and up kept, and the more i read about this i am finding out its a problem that everyone is getting with this 6.2 litter engines. The dealer wants to charge me 30k to change the engine and radiator and cooler lines on an already ridiculous overpriced vehicle. I am not sure why there hasn't been a recall issued perhaps because it involves a new engine? over700k people have the same problem. if thier is something you guys can do i dont think its correct the customers have to pay the dues on an unsafe bad design engine. Thank you for your time
