Two problems related to check engine light on have been reported for the 2005 Chrysler 300C. The most recently reported issues are listed below.
Whenever I do a quick acceleration, my check engine light comes on and the car temporarily lose power. When the car lose power, I cannot control it, which is very dangerous. When the check engine light comes on no codes are stored. Also, I have experience this problem while sitting at a red light. For the most part, this problem mostly occur during acceleration. I have had the spark plugs replaced and throttle body cleaned but the problem presist. From my research, this problem appears to be regular throughout the Chrysler/Dodge family. This problem needs to be rectified before someone lose their life in an unnecessary accident.
On 3 separate occasions immediately following filling with gas, the engine died within 2 blocks of the gas station. No check engine light was displayed on any of the 3 occasions and the car was extremely difficult to restart, requiring at least 30 seconds. Also, after restart on all 3 occasions, the engine ran very rough for 1-2 miles and then ran smoothly. On 1 of the occasions, the car died the next day after only driving a few blocks from home. After the first occurrence, the spark plugs were changed, the throttle body was cleaned, the vapor canister was replaced, and the evaporation system solenoid was replaced. On 1 of the occasions, the gas tank was topped off beyond the initial shut-off by several tenths of a gallon. After the 3rd occurrence (70,796 miles), the car was taken to the olathe Chrysler dealership and diagnosed as needing to replace the gas tank (2/20/2013). The cost was $1583. 58. Since then, the vehicle now has 72,062 miles . . . Approximately 1200 miles since replacing the gas tank . . . And has not died following filling with gas (6 times).
