Problems with 2014 Cadillac ATS TIRES

****gm said that the tire were worn that is what caused the crash** i was involved in a car crash on 8-11-14. my husband brought my a 2014 cadillac ats for my birthday. a few months after ownership i noticed that when it rained the car would hydroplane but the stabilitrak would make the vehicle jump back into it's lane. my husband thought i was being a brat, so i told him to drive the car. he took the car for a test drive and less than minutes into his test drive he said, ?call the dealership and get these [xxx]tires off this car now? ! i called the dealership [xxx] and left a message with [xxx][xxx] and explained the problems with the tires and to switch to regular tires not the runflat tires. she never called me back. a few days later, my daughter and i crashed. the car hydroplaned and lost control we hit two tress and took down a one way sign. my daughter and i suffered horrible injuries. i made a claim with gm esis dept., they denied my claim stating that the tires were worn and speed. i had no more 5000 mi. *tr information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

I have 2014 ats cadillac 4.0 t ( with run flat tires)..when it rains while i'm driving at speed over 35 mph or higher my vehicle will hydroplane but will jump right back because of the stabilitrak stability control system. this was the most terrifying thing to experience. i had to pull over and get myself together. i called my husband to inform him of the issue, which he later experienced the same freighting ordeal. no matter what driving mode the car performs worse in the rain. i like in michigan and if my car acts like in the rain i'm terrified and will not drive my car in the snow too. i refuse to drive in the rain....i am truly scared for my life. *tr
