The contact associated the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The traction control warning light was intermittently illuminated. The manufacturer was notified of the failure by phone and informed the contact that the VIN was not included in the recall. The contact was referred to a dealer to determine whether the failures were associated with a recall for coverage consideration. The contact stated that a coworker's vehicle experienced an identical transmission failure, and a transmission specialist diagnosed that issue as a torque converter failure. The failure mileage was approximately 140,000.

The catastrophic power failure with no warning on my 2017 GMC Sierra, at 87450 miles completely contaminated the engine oil cooling lines with metallic debris and fractured structural mounts. The servicing dealership replaced the transmission but is refusing to remediate the engine line contamination without out-of pocket payment. The vehicle cannot be safely operated without causing terminal engine failure on the highway, creating a imminent mechanical and traffic safety hazard.

I had an engine rebuilt completed on my L86 2017 GMC 6.2. After the repair, the engine failed due to the crank shaft on the engine being oversized which is the same problem that GM is having with the L87 engines. When the crank was ordered from the dealer for my L86, the only part number for the crank that was available was the new part number that was being used in the L87. Seems the same cranks were used in both engines and this recall on the L87 should be extended to anyone that had a rebuilt complete. Me and my family were left on the side of the road for a few hours which endangered our lives. The problem was determined by an independent service center and was fixed by the purchase of new parts and aftermarket bearings for the crank to allow the oil to enter the crank properly. There were no warning signs. Was driving down the road, started to hear a noise and then the engine started to over heat so that is when I stopped and called a wrecker.

Dear Sir, I currently own a 2017 GMC Denali that had a potentially catastrophic failure with one of the alloy wheels that are on my vehicle. Mileage about 110,000 I recently went to have new tires installed on my vehicles when the tire shop manager came from the work area and said that he could not put a new tire on my one wheels. The reason the tire store could not put a tire on that wheel is because two of the spokes on the alloy wheel were broken. There were three spokes between the broken spokes. The are 12 spokes on the wheel and the two broken spokes were non adjoining. They were not next to each other. There were good spokes between the broken spokes. With a close inspection of the wheel there is no scuffing or impact damage to the wheel either on the outside of the wheel or the inside that would cause this failure. The spokes just cracked. The fact that the two broken spokes are not next to each other would seem to indicate that this was a manufacturing defect. I am writing to go on record of this failure of the alloy wheel on my truck. If someone would like to inspect the wheel, please contact me to arrange for a time to look at it. I have attached pictures of the wheel with the broken spokes. Regards, [XXX] You can see the cracked spokes at the 12:00 and 7:00 position on the wheel towards the center of the wheel.

I drive this vehicle on higher speed roads to work everyday. Roads also used by large tractor trailers and like larger vehicles. I was told by dealer that I had broken exhaust manifold studs at a previous oil change. While driving the truck it seemed to lose power for a short time but I was in traffic and assumed the loss of power at that time was related to a possible exhaust leak.I scheduled a appointment to have the repairs addressed. When I picked up the vehicle I was told that there was a ticking noise in the top of the motor. They stated it was the lifters and needed to be repaired for $7136 dollars. I researched the problem and found out how big of an issue this is specifically for the owners of the 6.2l (L86) engine. Highly concerned I schedule the repair and dropped the vehicle off. Shortly after the dealer called and stated the vehicle had bent push rod collapsed lifters damage to the cylinder head, camshaft and worn camshaft bearings now cost are $14350 or replace engine for $17000. I chose to replace top end. The next day I was called back and was told the bearing on the cam journals were down to brass and I would need new engine. Cost in just 24 hours not are $22000. This vehicle was maintained by this dealer also for all fluid changes. The belief is all the failures were related to the active fuel management system. (going from 8 to 4 cylinders ).

The vehicle was towed to an independent mechanic, where it was diagnosed with lifters failure. The contact was informed that the lifters and camshaft needed to be replaced. The contact was informed that the lifter's failure had damaged the camshaft. The vehicle was being repaired. The manufacturer was not made aware of the failure.

The rear window on my 2017 GMC Sierra shattered unexpectedly without any impact. The vehicle had been remote started in very cold weather and the rear window glass suddenly shattered while the truck was parked. There was no rock strike or external damage that would explain the failure. I later learned about GM Customer Satisfaction Program N192265660 regarding rear window defroster thermal events affecting certain 2014–2019 GMC Sierra and Chevrolet Silverado trucks. Based on the sudden failure and the conditions at the time, this appears consistent with that issue. The Auto Rear Defog feature in the vehicle settings was turned off, however the truck had been started using the remote start feature when the glass shattered. Photos of the shattered window are available. I am submitting this report because the rear window defroster system may cause the glass to overheat and shatter unexpectedly.
