ENGINE, STRUCTURE:BODY
The vehicle one week after purchasing has had a tapping noise coming from engine and a rattling noise as well that you hear from the inside of vehicle. I have taken vehicle to two separate GM dealers. The first being where vehicle was purchased and they did not log in visit and basically said nothing could be done until engine breaks. The second dealer was only able to duplicate the rattling noise but had no loaner for me and advise would contact GM for next steps since a complaint has been filed. As of today nothing has been done. The second dealership also confirmed orange peel on paint and nothing either.

ELECTRICAL SYSTEM
The Telematics control module became defective and could not communicate with the BCM and serial data gateway module, causing a check engine light, loss of ONSTAR communications, clock, navigation, and remote vehicle-to-app communication. This part was known to be defective by GM. GM replaced the part starting in 2021 on Escalade models but not others. Service update # N212331730. The TCM became defective less than 24 months after purchase. The dealer stated the vehicle was over mileage for the warranty. The total repair cost was $1846, of which $1110 was labor. Replacement of the TCM was required to clear the check engine light.

SERVICE BRAKES, ENGINE
On February 14, 2025, my brakes went completely out in the school carline while picking up my youngest daughter. After the incident happened, I saw a light that read "Service ESC." This private elementary school is next-door to a private high school. There were students, teachers, and parents walking in this area at this time. I had to maneuver through this carline and away from faculty, students, and parents with no breaks. No individual was injured or killed but it could have been a very serious accident. I called GMC asking for help but was told through a chat line to bring the vehicle in for service. I was finally able to get my Yukon to the service department where after a few days it was determined my brakes failed and they were replaced. One day after I received the vehicle back from service, there was a horrible noise while driving but no lights showed on the dashboard, so it was returned to the same service department. They found metal shavings in my oil and I was told the lifters had collapsed and the engine failed. At this time, I have not heard from GMC and my vehicle is still in the service department.

ENGINE
i was with my entire family 3 hours from home on a ski trip loaded with gear and the motor decided to go. i had to pull into an abandoned lot, leave my family in a car with no heat, walk 6 miles up a mountain to get another vehicle and pick up the family. Then i had to call a local tow company to drive out pick up the vehicle and myself and drive 3 hours home drop the vehicle at the dealer and then myself at home. The vehicle was not even pulled in for 2 weeks to be looked at (no other vehicle was available) and then they told us the motor was shot - lifters cam and other things and that the head gasket was on back order indefinitly. This happened the beginning of February its now March 6, the vehicle is in pieces at the dealer with no time frame of when we can get it back. Meanwhile its costing me 1670$/ mo plus insurance. For a 100k$ vehicle to go with 30k miles is wildly unacceptable. I have had no luck getting a return call from a representative with GM which is why i am filing this complaint now.

ENGINE, UNKNOWN OR OTHER
My vehicle started making a terrible noise. I had it towed to the nearest GM service center. It was determined that the vehicle, a 2023 Yukon Denali (less than 26000 miles) needed a new engine due to thrust bearing failure causing the engine block to be scored and contamination of debris internally.

ENGINE
The contact owns a 2023 GMC Yukon. The contact stated while her husband was driving at 75 MPH, the vehicle independently accelerated without depressing the accelerator pedal. The check engine warning light was illuminated. The contact stated that the transmission started to downshift, and the vehicle started losing motive power. The contact's husband merged to the side of the road and turned off the vehicle. While the vehicle was off, the message to press enter to start the vehicle was displayed; however, the vehicle failed to restart. The vehicle was then towed to a dealer and diagnosed with total engine failure. The local dealer was contacted; however, the vehicle was not repaired because the vehicle was not under recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,000.

ELECTRICAL SYSTEM
The digital instrument cluster blacks out randomly at times going down the highway. This is a safety concern because you can't see how fast you are going. The problem has been inspected by and confirmed by a dealer service center. The failure began without warning and seemed to occur after the car went through a GM software update. The service manager for the GMC dealership said this is likely a bug that GM will have to solve through future updates. The car's electronic system was reset but the problem persists.

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

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.

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.
