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?

Accelerator pedal gets stuck on Chrysler 300 C and car keeps on accelerating. Even when slamming the brakes the car keeps accelerating. This is a major safety problem. We called Chrysler to report the incident and there is no recall or solution proposed. This is a significant problem since the car has a 5.7 liter engine and acceleration can be very forceful. People are going to be hurt because of this. There was a recall for similar problem on other vehicles from the Chrysler company but not for that vehicle.

I had this happen several times after I would fill up with gas. At about 30mph or when I would come to a stop and then try to accellerate the car would stall and cut off. Would then try and restart the car after several attempts it would finially restart. Sometimes when I would reach speeds of 55mph it would cut off and I would have to steer with the best of my ability to pull to the side of the highway. Finially I just took it to the Chrysler dealer and had them put a new evap canister on it and new trottle something on it 600+ dollars.

After filling up at the gas station the car stalled 3-4 times before beginning to surge. After several minutes of stalling/surging, it was fine. It does it every time the car is filled now.

I filled the tank and the vehcile stalled several times the next few miles. Especially after right turns, like when merging onto freeways. This happens now every time when I fill the tank. Very dangerous. From web forums I understand gas is getting sucked into the evap system because a check valve at the gas-filler neck doesn't work. What a pain! I replaced the evap solenoid, that didn't help...the problem at the gas tank filler-neck check valve.

The contact owns a 2005 Chrysler 300C. The contact stated that while driving 75 mph, the accelerator pedal fractured. The contact had to manually depress the accelerator with his left hand and maneuver the vehicle to safety simultaneously. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure and current mileage was 76,000.

The gas pedal accelerates and sticks so you lose control off the speed. It is very unsafe for children or for anybody to be in the car.
