One problem related to manifold/header/muffler/tail pipe has been reported for the 2001 Chrysler Concorde. The most recently reported issues are listed below.
Engine light repeatedly comes on. Have taken it to the dealer at least six times and was told that the intake manifold sensor was defective. The dealer contacted Chrysler, and was told to replace the sensor again and rewire the portion of wiring on the engine harness. This worked for two days and the engine light came back on again. I was told by the dealer to bring it back in and they would contact chrsler again. On the fourth attempt to fix the problem Chrysler said to replace the power control module. The dealer installed the module and the car seamed to be fixed. Unfortunatly the problem reappeared two weeks later. I have since given up on Chrysler fixing the problem and my engine lite continues to go off and on at least 5 days a week. The problem that I have with this is the fact that if something happens to the engine internally I won't know that there is a problem because the engine lite is already on. I am fed up with this car and the lack of support that Chrysler has shown during this time frame. They were more that happy to sell me the product but when something went wrong with the product they won't back up their five star dealers ( ha! ha!) any feed back would be greatly appreciated. Thanks, kendall .
