1999 Chrysler 300M Engine cooling Problems

“While driving at highway speeds of 65-75, car stops running. After pulling off the road, it restarted after 30 minutes. Mechanic could find no cause. No problems for 2-3 days of driving and it did it again stranding my daughter-in-law and her baby. Mechanic replaced fuel pump. A couple of days later it happens again. Mechanic now has the gas tank off the car. I have seen 9-10 similar cases for the 99 300 and later years. Help! This is dangerous and costly.”

“1999 Chrysler 300M - have had the car since 2002. About a year ago we noticed it would stall during operation then immediately restart. Now it has gotten worse. It just stops while at highway speeds, during city driving or even at a light. Usually re-starts right away but lately it takes about 10 minutes before re-start is possible. Took to dodge dealer and they cannot find the problem. I won't allow my wife to drive the car as it is too dangerous. Any feedback on what the problem is would be greatly appreciated.”

“The evaporator coil needs to be replaced. 1 month after I purchased this vehicle used, I returned it to the dealership because I was having problems with the A/C making a whistling noise and not cooling properly.it was still under warranty at this point and they found nothing wrong. I took it back 2 more times since then and finally on the 3rd try they diagnosed it as a evaporator coil.I am trying to get the dealership/Chrysler to pay, we'll know tommarrow.”

“1. Normal everyday driving. 2. Radiator/condenser cooling fan burnt up; could smell electrical components and saw smoke coming from fan unit. Blew 30a fuse and smoke/smell stopped. A/c quit working due to fan quitting and fuse blowing. I was on my way back to dallas texas from georgia when this blew. Luckily the car kept running on one of the two fans, and it was at night when it wasn't so hot! Had to replace dual cooling fan unit. 3. Replaced dual cooling fan unit and 30a fuse. $300.00 repair done by myself since the car is not in warranty.”

“In 7/03 car died on highway at 75 MPH with no warning finally managed to get it going again and left at dealer. Dealer said it need tune up. We replaced plugs, EGR, and cleaned map sensor. In 9/03 same thing happened on highway, this time dealer said to replace map sensor. We did. 1 week later same thing on highway again. Managed to restart and drive to dealer. This time it was powertrain control module. Dealer replaced. On way home from dealer car ran rough and died. Dealer said it was throttle position sensor. We replaced. …”
