One problem related to engine oil leaking has been reported for the 1999 Chrysler Concorde. The most recently reported issues are listed below.
I experienced complete engine failure while traveling at 55 mph on route 295 in new jersey. First I heard a sputtering sound then the car lost power. I had to cross from the fast lane to the shoulder while losing power. I just made it to the shoulder when the car stopped for good. There was plenty of oil in the car and in fact it had just been in the shop for another costly repair of $1500 for a leaky air conditioner compressor. A bad smell had been coming into the passenger cabin whenever I turned on the heat or air conditioner. After having the car towed I was told that by the mechanic that this car was notorious for engine failure and that he could see metallic material in the oil clearly showing the engine was blown. To repair it with a rebuilt engine it would cost $5900 plus tax.
