Ignition Module Problems of Chrysler 300C

While driving on the interstate at night, our 09' Chrysler 300 completely shutoff unexpectedly. Engine shutoff, loss of power steering, no power brakes. . . And worst of all, all lights shutoff! I drift off into the emergency lane (luckily minimal traffic) and stop. Put in in park and restart the vehicle. . . No warning lights, no issues, as if nothing happened. Continue on with life. . . Now a while later, I'm driving around a tight roundabout at a low rate of speed. And it happens again! loss of power steering in a turn at low speed, and the wheel gets ripped out of my hand as the car drives up over the curbs before I can stop with the now non-powered brakes on the car. Minimal damage to vehicle but enough to piss me off to know that this can literally happen at any time. . . Changing between having power steering to instantly none is a major hazard in a turn. I can deal with an engine turnoff, but this is a complete shutdown, as if the car was shutoff not recognizing a the key is there. Lights, radio, dashboard, etc. . . . All turn off (I'm guessing airbags too?) I have now researched this and I am far from the only one with this issue. It is pretty much narrowed down to a disconnect between the wireless ignition node and the key fob, and the module thinking the fob has been turned off when it fact it hasn't. Chrysler has recalled this part for model years prior, and after 09', but have seemed to skip the 300c for 2009. Well guess what, 2009 300c win module's are faulty also. . . And just as dangerous an issue as any other vehicle that completely shuts down randomly. This needs to be looked into and there needs to be a recall for 2009 Chrysler 300's for the win module and the key fobs! regards.

The main grounding wire passenger-side engine block contact point had corrosion(rust) limiting electrical current flow to the wiring harness. This caused too much current to flow to 2 smaller 16 gauge grounding wires attached to the rear of each hemi cylinder head to fry. This directly affects the ccn bus communications to the cpu. Any device, module, or sensor attached to the ccn bus can have intermittent behavior. Examples of very bad behavior in my car: 1. The alarm randomly going off while parked or when driving the car. 2. While parked and the alarm set the sunroof decided to open up during a rainstorm filling my car with 3 inches of rain. 3. The 300c doesn't use a throttle cable. It utilizes a throttle position sensor that communicates with the cpu over the ccn bus. Just touching the gas pedal was the same as pressing the gas pedal to the floor. It's a good thing that when this happened to me there was no traffic on the road and I was close to home. Since this is ccn 2-wire twisted pair bus communication issue anything that communicates with the cpu can have a random intermittent problem. Since these cars are getting older I have to think that there are other cars that are or will have similar issues. Pray to god that your throttle doesn't stick wide open like mine did. I had to keep my foot buried on the brake while I was screaming down the road until I was able to turn off the ignition. Have fun coming to a stop or driving home after that happens. Formally I was an i2c bus communications(2 wire bus) expert at both intel corp and cisco systems. I know what I am talking about. Today I talked with a bremerton Chrysler/Dodge/Jeep technical service representative about this issue. Bottom-line over $3000 to fix. There may have been somebody somewhere that is dead because of this factory defect and no one is the wiser. Why not a factory recall issue?.

The contact owns a 2009 Chrysler 300c. When the vehicle was parked, it took several attempts to get the key out of the ignition switch. The failure occurred on multiple occasions. The vehicle was taken to the dealer where it was diagnosed that the key fobs and win module needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 94,030.

Win module failure, key sticks in ignition and will not release key in off position.

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.
