Car would die after coming to a complete stop, and would not start afterwards. Would take a few tries, and waiting 5-15 minutes before the car would startup again. Currently getting car looked at at a shop to see if it is due to the crankshaft position sensor.

Car stops while driving. Very dangerous. Can't be restarted. Fuel pump, filter, crank shaft sensor all replaced. Still does this. Same symptoms as before the repair work done. ($1200) Now they want to test the keys.

Gettting on fwy onramp and lost power while accelerating. The car would not go over 15mph. ESP light went on. Pulled over to shoulder and shut off car, once I turned back on light went off and car returned to normal, for now. Taking to dealership but feel very unsafe now.
