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 am an auto tech at dealership in ks. After 3 repeated incidents, I decided to take action. On either side of the front bumper the fog lights get hot and eventually detach from the lens. The 2nd and 3rd time I have noticed scorching on the vehicle's front bumper where the bulbs started to melt the material. The 4th vehicle caught fire to the bumper and it spread to the engine. This could have been worse without anybody attending the vehicle and more in a house garage. It did not take very long to melt and ignite.

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. …
