Ok so my car does a lot of weird stuff. i have had it for about 3 years now. First, the ABS Trac OFF and Service engine soon light is always on. A mechanic told me I needed a new wheel bearing. Did it, did not work. Then my turn signal clicker clicks constantly not in any certain pattern its just every so often it will start clicking a lot. Then sometimes I go to start my car and it will not start. The security light comes on and the car will turn over and try to start but does not fire up. I would like to get the security light problem fixed more than anything. Also, sometimes it will shift really hard and other times it does not. Some people have suggested to me that it might be the computer?
