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?

My turn signals at first were not canceling, and then stopped working completely. However, the right turn signal is stuck in the on position and flashes continuously. Also, after driving for one mile an alert signal starts dinging continuously to let you know that your signal is still on and it never goes off. I have had to remove my turn signal bulbs completely so they would not continuously flash on the outside. This whole situation is unsafe because I do not have any use of my turn signals, and even though I use hand signals people just aren't looking for that . I have even been pulled over by the police for failing to use my turn signal even though I was using my hand signal. Also, in an emergency situation I have no use of my hazard lights(flashers). I have looked online to see if there are any similar complaints concerning chrysler 300's and I found thousands people with the same issue or in the beginning stages of the signals failing to cancel.

I dont know but what I do know is im tired of spending money on everything I was told that it could have been n til this day it's still not fixed . I. Was put in danger a many of times me n my 4 children's lives were in danger just in the midst of traffic it shuts off,at any instant any given time I can get hit from behind due to the many times it shuts down,the vehicle automatically loses control along when that happens it is very hard to steer the wheel in a way where I can make a complete stop,making it very possible to hit anyone ongoing in other lanes ,it has been very dangeroud for me n my children.I just wish this vehicle can ne brought back so that me n y four children wouldnt be facing danger everytime we enter the vehicle,its just an everyday thing ongoing. I truly want something safe, just hope I dony have to come out of pocket no more than what I already have for the same thing and it hasnt been fixed yet. I dont want it anymore iwant this vehicle off my hands now,its not what I want anymore,me n my children have been placed in much danger because of this vehicle. I am sorry,but I truly thought this vehicle was nice,not anymore!
