Car fish tailed uncontrollably and ended up crashing into a Ranch Fence on the right side of the road. 2 of my kids and myself had injuries.

The first incident started on 08/16/2024, 2 days after buying the vehicle used from Dealership. I started getting notifications stating "Service-Front Camera not available" and sure enough, I no longer had a front camera, which then means I no longer have front collision alerts. Then I started getting the random notifications to drive carefully because drivers assistance has been reduced, and now my vehicle's fan will randomly run for up to 30 minutes after it has been shut off and even after a less than 2 mile drive to gas station and back home, it does this. Last item is the vehicle pulls to the right, and I have not hit anything nor has it ever been in an accident prior to my purchase, and my brakes squeal horribly, which shouldn't be happening condidering I haven't even driven the vehicle 5,000 miles in the year since I bought it !

The contact owns a 2021 Chevrolet Blazer. The contact stated while driving 35 MPH, the ambient air temperature was stuck on negative forty. The contact replaced the sensor. The vehicle went into ICE/SNOW Mode on several occasions and was not driving as designed. The air conditioner was blowing out hot air. Additionally, the vehicle was pulling to the right while driving. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who scanned the vehicle and determined that the sensor was operating as designed. The mechanic informed the contact that there was a loss of communication. The vehicle was taken to the local dealer, where it was diagnosed that the control arm needed to be replaced. The vehicle was repaired, but the failure recurred. The dealer informed the contact that there was no recall coverage on the vehicle. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 34,980.
The Esc display came up then sutbality sensor show and my back wheel went right. My car flipped twice and then landed on the guardrail.
