2019 GMC Sierra 1500 suspension problems

SUSPENSION

Several months ago while having my truck serviced, I asked the repair shop to inspect the ball joints on the passenger side because they would make a popping noise when turning the wheel. The shop inspected them and said that was a normal sound due tot he factory lift. Recently I was driving home and about to turn into my lane when the front passenger wheel assembly collapsed under the truck due to the a upper ball joint failure separating the brake line and loss of steering. At the time, I was only going about 25mph and the truck slid to a stop on its own. The truck has 65,000 miles on it and if this had happen at highway speeds personal injury to myself and others would have been likely. The repair cost were $7,500. Fortunately I purchased an extended warranty which covered all but $1,700 of the repair.

While driving 13-15mph down the road the front right upper control arm ball bearing sheared off causing the tire to lean in rubbing the wheel well, forcing my truck to veer to the left across the other lane of traffic. Luckily there wasn't any car next to me.

I was driving the vehicle heard a loud thumping sound got out to look and the driver side tire was nearly off the vehicle! Had I been driving on the highway I could've been killed/seriously injured by loss of control by way of steering. It looks like the upper control arm completely seperated from the tire at the ball joint causing the tire to fall away from the vehicle. There is a current recall out there for this make, year, and model. The vehicle has been inspected by the manufacturer. No warning lamps or messages have appeared.

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.

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.
