While driving home with my pregnant wife at night, car all of a sudden stalled. After coming to a complete stop, car was put in park and restarted. Go out and inspected car even looking under hood. Nothing looked out of place so restarted car. Check engine light came on but car made no unusual noises and drove the last mile home with emergency flashers on. Car stalled once again one block from our home but again restarted. Took it to the dealership the following business day for a diagnostic where I was told it was the crankshaft position sensor and was not covered under the powertrain warranty. Total cost including labor to replace sensor was $224. This is a major safety issue. Thankfully my pregnant wife was not on the highway during heavy traffic. I called Dodge to inform them of the problem and they documented but didn't seem very concerned with issue. Again, stalling on a busy highway can result in a major accident.
