ENGINE
I was traveling on the highway when my 2023 Yukon Denali engine shut off and switched to the neutral gear with any warnings. The dashboard display read "press start again" as I coasted to the shoulder of the highway. I was able to put the vehicle in "park" and re-start the engine after a couple of tries. I got a couple miles down the road, got off on an exit ramp then it shut off again and I again coasted to the shoulder of the highway. Again the display read "press start again", but this time the vehicle would NOT restart at all. I had full electrical power in the vehicle during both engine failures. I had the vehicle towed to my local GMC dealership. The dealership told me that I needed a new engine after assessing the vehicle.

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.

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.

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.

SERVICE BRAKES
On two occasions while driving at low speed, my vehicle braked on its on a pulled hard to the left; the stabilitrac indicator also popped on briefly. I went online to determine if there were any recalls on my vehicle and found that one of the recalls on the 2016 Yukon was the exact issue happening with my vehicle. I checked my VIN and found that my vehicle was not one of the vehicles with this issue. I called GM to see if my vehicle had just not been published yet. I explain the situation too the customer service person; she understood my situation and informed me that until my specific VIN in identified with this issue, there's nothing that can be done. I'm thinking that until an accident happen because of this issue, there is nothing that can be done. I read that my issue was a problem with the EBCM, which needs to be reprogrammed. I thank you for any assistance with this issue.

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.

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.
