Ignition Module problems of the 2006 Chrysler 300C

The contact owns a 2006 Chrysler 300c. While driving 65 mph, the vehicle stalled without warning. On several occasions, the vehicle independently restarted. The vehicle was taken to the dealer where it was diagnosed that the battery and ignition module needed to be replaced, and the vehicle needed a tune-up. The vehicle was repaired; however, the failure recurred. The contact stated that the failure was intermittent. The manufacturer was not notified of the failures. The approximate failure mileage was 120,000.

My 2006 Chrysler 300c (hemi 5. 7) will stall at low speeds or when stopped at a traffic light. The car does restart. At higher speeds (e. G,, 60mph), the vehicle will exhibit a sudden loss of power (drop in rpms, followed by a chime sound) as if the engine is about to stall, before reaccelerating again. The stalling/loss of power issue does not occur all the time. Sometimes, the car will operate as long as a day or two without incident. The dealer performed a complete system diagnostic - retrieved code po700 - related to loss of communication with pcm to multiple modules. (they may have been old stored codes. ) then, they cleared the codes, road tested the car, but could not replicate the problem. The dealer returned the car and asked me to monitor it. They indicated that if the issue re-occurs, the vehicle will possibly need a pcm or ignition switch. My impression is that they are guessing at what the issue may be. The day after the car was returned to me, the same sudden stalling/loss of power issues reoccured although the engine diagnostic light has not come on. I will be returning the car to the dealer, even though they have not been able to pinpoint the problem to date. I am very concerned about the sudden stalling and loss of power. This is a very serious safety issue that can result in an accident. I am married with a 9 month old baby.
