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 miles at the time of the crash. There is no way the tires were worn nor speed. I took my car in for the lease maintenance package the dealership (Suburban Cadillac) did tire rotation and at time there was no mentation of my tire thread wearing down. When I mentioned to service dept about the problems with the tires the explanation I was given is that the run flat tires are like the big wheel (child plastic tricycle from the 80's) tires when it rains that's why plus tire are low profile. I contacted my state attorney general (no help), BBB (going through procedures currently), ftc (made a complaint), and contacted NHTSA(no help at all) to get help for an investigation and for GM. As a citizen of the United States I am so disappointed with the lack of support for the people that are supposed to assist citizens like me.

I have researched and found other owner that have experienced the same exact problems, but I am the only person that almost died. GM is giant company and I have no voice for the companies/organizations that are supposed to assist me. GM they claimed that my tires were worn when I purchased my car it had only 2886 miles and when I crashed I had a little over 7,000 miles, that is impossible for my tires to have been worn! GM is obliviously trying to cover the issue

I turned a corner, drove through some sand on the road and broke traction. After that, the traction control system lights came on and within several seconds the check engine light came on. I had onstar service run remote diagnostics and they found ABS failing and a cylinder misfire. The car took an immediate loss in power and started to shake at all power levels.
