One problem related to engine squeaking noise has been reported for the 2000 Chrysler Concorde. The most recently reported issues are listed below.
I have a 2000 concord, kept in mint condition, oil changed every 3 to 3. 5k just turned 80k. While picking my fiancee from the hospital on the x wat, I heard a click kind of sound from the engine, I exited the ramp and pulled over, the engine w3as making a squeaking sound, all equipment on this car is of oem. We had it towed home . It appeared that the oil sending unit was squirting oil, I was told that I needed an engine replacement. Contacted Chrysler corp. Via email, was told that it was out of warrently. The car is sitting, I can barely keep up my house payments, yet an engine. Have to worry about borrowing cars from friends to get to work. I have taken extra care of this car so it would last me. All I ask is for a little help. I am in despair.
