My car has malfunctioned and been "repaired" three times. Each time the car malfunctioned, the gas pedal stopped working and the car began to slow. The gear indicator light switched from d to p and back again, over and over. The check engine light started blinking and later turned solidly on. Since it was just coasting, I had to pull over the car and in each case I was lucky enough to be in an area with a decent breakdown lane. At one point when the mechanics were pulling the vehicle into a bay, it started doing this and the reverse lights also started blinking. In addition, it jerked back into drive, jumping forward. Thankfully no one was close to it. So far the repairs have included an ignition coil pack, spark plugs and wires, replacing two bolts and reprogramming, and replacing the transmission control module for a grand total of over $2,000.
