“I was driving about 35mph going straight when my chevy Blazer acted as if it 'hit a brick wall' and came to a complete stop. I got out and noticed my right, front wheel was completely smashed into my car. Something had come loose internally and locked up my wheel. It damaged my car so bad where my suspension was damaged. It had to be towed. It was non drivable. My vehicle only had 1300 miles on it. I decided at last minute to not get on highway.”
