I have a 2009 Corolla and I have been having problems with the steering. On highway speed, I feel that the steering wheel suddenly pulls to the right or left but more so to the right and it scares the heck out of me. I have taken it to the car dealership and the mechanic said that there's nothing wrong with it. How can he say there's nothing wrong with it when he only drove it for 7 miles back and forth? I have seen several complaints on the nhtsa.gov website and they all say the same thing. What is going on? I don't feel safe driving the car and I only have it for about 3 weeks now. Please help.
