I was detailing my car, put my foot on the brake and put the car in neutral so I could vacuum out the compartment below the ash tray. Held my foot on the brake until done, put the car back in park.
Now I have three new warning lights, ABS Malfunction, ESP Malfunction and pre-.......

After reviewing similar cases online, I tried disconnecting the battery and turning the steering wheel full left and the full right, no luck. Also replaced the stop light switch and sorry to say no luck again!

Car will drive but in a sluggish mode and stering is hard.

Any suggestions?
