ENGINE, POWER TRAIN
Vehicle Information Make: GMC Model: Yukon XL Denali Year: 2021 VIN: [XXX] 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The engine failed due to defective lifters and camshaft components, along with excessive oil consumption. These issues rendered the vehicle inoperable and required over $10,000 in repairs. The failed components are available for inspection upon request. 2. How was your safety or the safety of others put at risk? The engine failure occurred while the vehicle was in motion, creating a dangerous situation for my family and other drivers. Sudden loss of engine power could have led to a collision or left us stranded in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was diagnosed and confirmed by DeFouw GMC in Lafayette, Indiana. GMC has acknowledged the defect and agreed to cover all but $2,000 of the repair costs. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by DeFouw GMC. GMC is aware of the issue under Case #[XXX]. No inspections have been conducted by police or insurance representatives. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No, it all happened at once. The vehicle was extremely well cared for, and GM has all of the oil change records. Additional Comments: We have been without our family vehicle since [XXX], and GMC has not provided an estimated arrival date for the replacement engine. We are now entering month four without a vehicle, which has severely impacted our family’s mobility and safety. This delay is unacceptable and reflects poorly on GMC’s commitment to customer safety and service. Has also cost us over $10,000 out of pocket, which I will seek reimbursement for legally, if I must.

ENGINE
Subject: Assistance Request – Vehicle Engine Failure Shortly After Purchase I am reaching out for assistance regarding a serious issue with a vehicle I recently purchased. Approximately two weeks after purchasing the vehicle, the engine failed completely. I was driving it to pick up my daughter from school and when I went to go from stopping at a red light the engine light started flashing, the car said lowering for stabilization, and it started smoking and wouldn't go. I was almost hit due to the engine just stalling. When I was able to drive it was shaking and I couldn't go past 30. I made it to the dealership that was 7 mins away and had a guy from service come out. There wasn't any warnings before the engine went out. The dealership has informed me that I am responsible for the repair cost even though vehicles of the same year, make, and model have an active engine recall for this exact issue. Despite this, the dealership and manufacturer have refused to cover or assist with the repair, and there is currently no estimated time for replacement parts or a loaner vehicle. I have documentation from Greg Hubler on there diagnosis. I believe this situation may involve a warranty, recall, or consumer protection concern, and I would like to know what steps I can take or if your office can assist with resolving this matter.

ENGINE
I had a complete engine failure in my 2021 Yukon XL Denali while driving 70mph on the highway. My vehicle warning lights all of a sudden came on and my cruise control was disengaged. My vehicle started shaking and then started smoking. It was taken to our GMC dealership immediately and it was discovered that the engine had failed even though my VIN is not listed in the L87 Recall. No warning lights appeared prior to this failure. I will attached our invoice from the dealership and their description of the problems.

ENGINE
While operating the vehicle at normal highway speed, the engine suddenly failed without warning. The vehicle immediately lost power, forcing me to coast to the shoulder. This created a dangerous situation in active traffic. The vehicle was later towed to an authorized GM dealership. The dealer inspected the vehicle but refused to provide assistance or take responsibility for the engine failure. Based on the symptoms and information available, the failure appears to be caused by a known GM engine defect. This issue poses a serious safety hazard since the engine can fail abruptly during highway driving, increasing the risk of accidents or injury. I am requesting that NHTSA investigate this matter and that GM be held accountable for addressing this known defect.

UNKNOWN OR OTHER
The rear view camera is not sufficient for full time use. The camera is positioned too low and during times of dawn/night/dusk if a truck of similar size pulls up behind you, your camera is completely blinded by headlights. Leaving you unable to see anything in the rear view camera. This is a serious safety concern as you are unable to see if anyone is approaching your vehicle to cause you harm. The low camera placement also does not allow for an acceptable/comparable view as using the rear view mirror. The zoom does not pull out far enough to see multiple lanes of traffic and even during the daylight, if someone is approaching the vehicle to cause you harm, it would not be visible. The camera placement only allows you to view the front grill or hood of the vehicle behind you.

AIR BAGS
Airbags did not deploy. A car run a red light. I hit it on its passenger side. I was going about 45mph before the crash. I did slam my breaks before impact but I would guess I was still going 30-35mph at impact. Car has not been inspected yet. It is still in our possession. We have made in insurance claim. No warning light of any kind were on before the crash.
