SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I were driving at low speed and all 4 wheels locked causing the vehicle to suddenly stop without notice. I almost got rear ended. I had to put vehicle in park and turn off and turn back on to get it to move. Again it did the same thing stoping with brakes locking suddenly, almost causing an accident in middle of road. There was no warning at all.

SUSPENSION
Driver's side front wheel assembly separated from the vehicle. It was hard to tell exactl what happened but I am told that it may have been a ball joint failure. I was driving in the middle lane on the highway with cruise control set to 70MPH. All of a sudden, my truck jumped up and my truck starting pushing towards the left median. I thought I had a tire blow out. Luckily there wasn't anyone in the left lane at the time and I was able to get to the grassy left median. If there was another vehicle in the left lane and or if the left median wasn't grass, this would have caused a major accident as I has no control over where the truck was going. When I got out I saw that my entire wheel had separated from the vehicle and it was on its face under the truck. I did not hit a pothole. There was no prior indication that anything was wrong with the assembly. A tow truck was called and brought the truck back to their shop. The assembly had to be replaced, (ball joint, axel, steering control arms etc.). I called my local GMC dealer and they have nothing being reported of this issue but when I looked online I've seen multiple reports of premature failures of ball joints. Total repairs so far have been $3,400.00 and I still need to replace a cracked rim. Repairs will be over $4,000 when all said and done.

ENGINE
According to inspection by my local GMC dealership, the engine oil cooler lines leaked/detached, as a result the engine assembly needs to be completely redone. When driving on the highway the car began flashing to immediately pull over and turn the vehicle off, the engine became very hot and was smoking and oil was found all over the ground upon inspection after immediately stopping the vehicle. This vehicle has been inspected by the Carlsbad GMC/Buick Dealership. There were no warning messages prior to this event. The car has consistently received all recommended preventative maintenance and oil changes. As a consumer I am now on the hook for over $15,000 in repairs, after complying with all maintenance recommendations from the manufacturer. There is an active recall for an identical model and make as this car for the same issue, the recall number is: N212326940 (customer satisfaction program number) and DCS5833 (Global safety field investigations number). I am very confused as to why this recall has not been applied to my vehicle.

SUSPENSION
At 50,000 miles the upper control arm/ball joint on the driver side came apart with no warning causing considerable damage to the suspension, tires, wheel, and front bumper. About two months before at approximately 48,000 miles the passenger side control arm/ball joint came apart again with no warning. Warranty has just elapse and GM has denied any responsibility and will not cover any of the repairs. This could have easily been catastrophic if we would have been on the freeway. This is a Safety issue! This truck has the aluminum upper control arms which my opinion for what its worth is the problem. I have no clue at this time how we are going to be able to fix this. Even when it is fixed we will never trust it.

Alarm codes P25A2 & C05B0 -Brake system failure 43mph top speed -Service trailer brake system -Service brake assist -Service ESC -Check engine light -Traction control light My vehicle is not showing any recall, but obviously I’m not the only one with this issue. A quick research on google revealed several people with the same issue. I’m having to pay for this out of pocket for an obvious issue with GMC & Chevy trucks.

ENGINE
Engine began having ticking noise. I took it to dealer for repair. Service department finds the lifters in my engine have failed and destroyed my cam shaft. They call me and explain it will cost $10,000 to repair. The service writer explains to me that they have 4 of these each week come into the shop. It is so common that they keep the parts in stock to repair. While I was waiting in the waiting room another person came in with the exact same problem. I later found that a repair bulletin has been issues for this issue but for some reason it does not apply to my vin even though it is the exact same problem.

ENGINE
While driving on the highway, I got a message that said "low oil pressure, turn off engine" with red flashing lights. I could also smell burning oil and metal. I immediately pulled over and turned off my engine. When I exited my truck, I could see all of the oil that remained in my engine leaking onto the ground. My truck was towed to a local repair shop and they advised me that this is a common problem in this truck. The oil line blew likely due to a defective crimp. The mechanics can't repair the problem right away because this line is on a national backorder and there is no aftermarket option. This obviously happens too often if this part is on backorder. The mechanics believe there may have been damage done to the engine as a result of losing all of the oil on the highway.

FUEL/PROPULSION SYSTEM
The connectors to the fuel pump have failed causing the truck to mechanically fail and not operate. This is a common problem per the diesel technician who diagnosed our truck and in his opinion should not be happening as often as it does. It’s specifically the cylinder 4 injector control circuit and diagnosis states the pins are corroded.

SEAT BELTS
Driver seat belt would not recoil. Took to Royal GMC of Tucson and they said it was not a warranty covered part and would not repair it unless I paid for the seat belt replacement. Obviously, I need a seat belt as a safety feature being the driver so I had them order the seatbelt and they installed it. See attached receipt. I believe this should be a warranty item from the manufacturer as it is defective and a serious safety issue. The vehicle is a 2019. I am the only one that drives this vehicle and I have never had any accidents etc.

ENGINE
The lifters were replaced leas that 2years under warranty at Pooler Chevrolet. They have stated this is a common problem with this vehicle and they had a lot of these vehicles come in with the same exact problem. Vehicle had no power, engine lights on and valve failure after being replaced before and the vehicle has less than 60,000 miles at 2nd failure. They stated the 1st repair has no warranty to cover such a catastrophic failure and I must pay out of pocket. I argued that it shouldn't have failed with less than. 60,000 miles any expectations of engine failure would be with massive miles and would be expected for some form.of major over haul. Caused emergency as i was in the middle of the interstate upon failure and I almost lost my life. I asked who was performing the repair and they won't answer the request about the repair. They stated it was sent out for repairs and not an in house repair. All repairs have been at GM certified center.
