2019 GMC Yukon Xl

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

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).

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.

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.
