May 31st 2022-While driving on the highway, I lost control of my power steering. Luckily my husband was with me to drive it back home. June 1st 2022-Took it to a service center and was told it needed a part to fix the problem. We ordered the part, which would not be delivered until may 6th 2022. June 4th 2022- Went to drive, made it a couple blocks down the road when the ABS, electronic stability control, & the engine light came on. So I turned around to take it back home, only now my power steering was completely out, my car would not shift out of first gear. After arriving home, I attempted to put it in park but was unable to. My motor shut off but would not allow me to place it in park or turn the electric power off. The only option I had was to disconnect the battery. I let it sit for a few hours, reconnected the battery, now my car will not start at all. I am now unable to take my car to the dealership due to power failure Note: June 2nd & 3rd, my vehicle was not driven I did contact my local dealer to check if there were any open recalls, was told

2014-2018 Chevy and GMC's have a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are GM bulletins on the 2014 and 2015 models. As one can see they have provided special coverage on the 2014 models to 5 years or 100000 miles for this problem.(Bulletin 15829) This is not true of the 2015 through 2018 like mine. Although they use similar verbiage in the bulletin P11513A and P11513F. It should be noted that Bulletin P11513A and F also applies to 2015 Cadillac Escalade Models, 2015 Chevrolet Suburban, Tahoe, 2015 GMC Sierra Denali, Yukon Models, Yukon Denali Models Equipped with 4.3L, 5.3L or 6.2L Engine (RPOs LV1, LV3, L83 or L86). ***Basically this is a safety hazard because when traveling highway speeds it puts car into reduced power mode and you can only drive very slow on highway or be stranded on side which is just as dangerous ***

I was driving my vehicle and exiting the hw. The rear wheel of the driver side broke off and separated from the car which caused my car to hit the cement beerier on front and the side of the driver side of the vehicle. Then the car turned 180 degrees and hit the beerier on the passenger side and the rear of the car. The air bags never deployed and we discovered that the wheel brook off of the rear axe. No damage to the wheel. Several industry exports stated that this should never happen.
