My car is going CRAZYYY
first thing first.. I was at my friends house and somehow lost my keys that I have still not found so my dad dropped of my spare key which is a valet key. Then I started the car up and everything was going fine until i looked to see how fast i was going. my speedometer was stuck at 0MPH! I thought that was strange because I had used the valet key before and I could always tell how fast I was going. and then further on down the road my dsc and brake light came on... does anyone have any idea whats going on.. I was thinking maybe a bad speed sensor or something.
any help would be greatly appreciated. Thanks
