Total engine failure with no warning. Vehicle has approximately 106,000 miles. While driving on Monday [XXX], the car began shaking violently and the engine light began flashing. Fortunately I was only about a mile from a GMC dealership, so I pulled into Rice GMC Buick in Knoxville, TN. They informed me that there was a catastrophic engine failure and that a complete replacement would be necessary at a cost of $15,000 dollars. I live 100 miles away in Chattanooga, TN. I understand that cars experience some level of wear and tear, but a total engine failure at just over 100,000 miles when the car has been serviced at all regular intervals is very unusual. I recommend my case be referred to active investigation #PE25001. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

GMC engines are faulty and puts people at risk when they malfunction. The first time the vehicle lost power, It was spitting and sputtering as i was driving with my family in the car. The vehicle Left us sit along side the road of a major highway in freezing temps. The lifters malfunctioned costing 5000 dollars in repairs. Once again started having loss of power and the vehicle shut completely down while driving down the road with my family in it. So no engine means no power steering an etc . Again left us sit along side the road. The main bearing has went in the motor. Now costing us 16,000 in repairs For new engine. Now we are at the cost of 21,000 in repairs. This is a known issue with the v8 engines a yet GM has done nothing to fix or compensate people for their loses. I’m stuck with this vehicle now cause I’m so upside down at this point it’s disgusting. Also sad an auto manufacturer doesn’t NOT stand behind their product as it puts people and their family’s at risk. They NEED TO BE held accountable for this issue as thousands of people have had this issue. I don’t have the other repair bill on me at this time do to the car is in the body shop from a deer accident. But I do have one an can provide it at a later date if needed. Thanks

SERVICE BRAKES, HYDRAULIC
The contact owns a 2019 GMC Yukon. The contact stated while driving 55 MPH, and approaching a red light, the brakes failed to operate upon the depression of the brake pedal. The brake pedal was firm while the contact steered the vehicle off the shoulder of the road. Due to the failure, the contact drove through the intersection and allowed the vehicle to coast to a complete stop. Upon restart of the vehicle, the "Brake Assist" message flashed on the instrument panel. The contact's husband was called to the scene and later drove the vehicle to an independent mechanic. The mechanic inspected the vehicle and discovered that the vacuum pump had failed. The vehicle was repaired by the mechanic. The dealer was notified of the failure and offered to inspect the vehicle; the dealer then referred the contact to the NHTSA Hotline to report the failure. The manufacturer was notified of the failure but offered no assistance. The failure mileage was approximately 131,600.

I have 98,000 on my Yukon XL Denali and I have a crack in the piston block as I was told by the dealer. I have an Endurance Car Warranty on the vehicle and the vehicle has been at the dealers since [XXX]. The warranty company is giving the dealer the run around where they have torn down the motor already twice to prove to them that there is a crack. Plus, there was no warning signs other than it not running smoothly as it has been and that is why it went to the shop. Nothing should be happening to this motor at 98,000. The vehicle is presently at Palm Chevrolet in Ocala, Florida and Scott Kelly is the service manager. Can you please give me some advice.

GM vehicles manufactured between 2015 – 2019 equipped with GM’s 8-speed transmission are equipped with a defective transmission design of GM’s Hydra-Matic 8L90 transmission or Hydra-Matic 8L45 transmission, which causes vehicles to suddenly lurch forward, shudder, and experience significant delays in acceleration. GM not only knew about this pervasive issue but developed a fix for it in 2018 – namely a transmission flush it calls Mod1a. However, GM made the business decision in 2019 to forgo recalling all impacted vehicles (approximately 2 million) to receive this flush, which would have cost GM about $305 per vehicle for a total $592 million, and instead decided to limit the flush to only unsold Cadillacs and trucks in certain states where it expected customers to complain within their warranty. Furthermore, GM never alerted existing customers of the issue or the fix and only addressed the issue if the customer was under warranty and complained about the shudder. GM marketed and sold these 8-speed automatic transmission vehicles as having “world-class performance,” lightning-fast and smooth shifting, along with improved fuel efficiency, and instead sold defective vehicles.” These conditions make it difficult to safely merge into traffic or back out of a garage/driveway. Even more troubling, the transmission defects cause the vehicle to delay downshifting and decelerating when the brakes are depressed. The affected vehicles include Chevrolet Silverado (2015-2019); Chevrolet Colorado (2017-2019); the Chevrolet Corvette (2015-2019); the Chevrolet Camaro (2016-2019); the Cadillac Escalade and Escalade ESV (2015-2019); the Cadillac ATS, ATS-V, CTS, CT6, and CTS-V (2016-2019); the GMC Sierra, Yukon, and Yukon XL, and Yukon Denali XL (2015-2019); and the GMC Canyon (2017-2019).

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, ELECTRICAL SYSTEM
My vehicles Electronic stability control is activating randomly. This issue started a few years ago and has increased in frequency. We will be driving at speeds between 50-75 mph in dry conditions and it will randomly activate which has almost caused us to lose control of the vehicle. No mechanics have been able to figure it out. I did some research and saw there was a vehicle recall issued for 2019 GMC Yukons Electrontronic Stablilty Control system, but for some reason it does not cover my vehicle. The GM recall number is N192261050. The description of the issue matches exactly what is happening. I called GMC and issued a complaint and also have setup a dealership to fix the issue. I don't believe i should be responsible for paying the cost of the repair since other 2019 GMC Yukons were recalled for this issue.

STEERING
Steering will all of a sudden feel disconnected. Feels like truck is sliding, till I move the wheel, then it feels connected again. Very weird feeling. This only seems to happen on the highway at highway speed. Witch is the part that worries me. This happens at least once every time on on the highway.

it's been a known fact and on social media there has been many complaints, why is there nothing being done. this vehichle has a water or moisture problem which goes to the electric connectors and makes the vehichle go in to derate mode and only code it throws is peddle position sensor. which I have changes, and still no fix, as other connectors that are going to the electronic board removed, and it has corrosion. this is clearly a safety risk and it literally puts in a mode where a truck is not drivable.

This car had catastrophic engine failure due to the lifters, push rods and camshaft. This car make and model and engine type is notorious for these specific parts to malfunction. This could have left myself and my children stranded on the interstate. The vehicle has been inspected by a certified master technician with ASE training. They confirmed that these parts are a common issue with these cars.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Service Trailer Brake System keeps coming on while driving. Dealership says nothing wrong although they replaced fuse. Still happening. Only thing that seems to work is pulling off road and restarting vehicle. That is only a,temporary "fix". Comes back a few days later. This is a safety issue as 1) distracts me while driving 2) I pull an 8,000lb travel trailer with the vehicle.

I actually own two GMC's one is a 2018 GMC sierra and this vehicle and they both have transmission problems. This vehicle has 100,000 miles on it and the transmission is gone, you want to charge 70,0000.00 for a vehicle that has a sup par transmission and to replace it cost over 6000.00. The sad thing is when I pulled up to the dealership and told the sales manager and shop manager my problem they just shook their head and said it won't be good and that they have had to replace a lot of them, so many that they keep the transmission in stock like wiper blades. This is utterly ridiculous and I have bought and paid for at least six or seven GM products in my life but this will be my last one I promise you that.

SERVICE BRAKES
I purchased this vehicle, new. I have never towed anything with this vehicle. Yet, the "SERVICE Trailer Brake System" warning has been flashing, endlessly for two days. The chime is distracting when it comes to driving and/or hearing emergency sirens, should they be nearby. I have not taken it in for service as this just occurred yesterday (4/27/2022). This issue makes the vehicle difficult to drive and feel safe.
