NHTSA complaint #10234232, filed 2008-07, 65,000 miles“On september 1, 2007, I had been driving on the highway at approximately 60 MPH for approximately 15 miles when the air conditioning suddenly began blowing hot air and the temperature gauge went above h immediately. I turned the air conditioning off, exited the highway immediately, stopped the car, and attempted to restart the car to remedy the problem, but when the vehicle was restarted the car was still past the h on the temperature gauge. …”
NHTSA complaint #10201798, filed 2007-09, 62,361 miles“I have a 2004 Mitsubishi Endeavor. A/c works some times in the city. Most of the time after driving on the open highway it blows warm air or not at all. The thermistor assy has been replaced as well as the resistor harness for thermistor assy. Did not correct he problem. Misubishi states (which is false) that the problem I am having was caused by the placement of a fin sensor by an independent garage. What is a fin sensor (never had this replaced) and do you have any suggestions. Thank you, bill”
NHTSA complaint #10221850, filed 2008-03, 60 miles“Early on a saturday morning, I was driving on a relatively traffic free l.a. Freeway. I happened to look down and notice the check engine light on and the temp gauge pegged. There was no other indication of a problem. Fortunately I was able to get off the freeway before the car stalled. Upon inspection a small hole was found in the front of the radiator. The problem seems to be a large grill opening with no screen or other protection. Normally the radiator is protected by the AC cooler. …”
NHTSA complaint #10106299, filed 2005-01, 9,591 miles“We noticed that the engine was smelling hot, but no warning lights were on, so we made an appointment with a Mitsubishi dealer, while driving it into the shop it began to overheat. After stopping several times to cool off the engine we made it to the dealer only for the car to just then get a check engine light on and stall completely out. We then found out that it was a hole in the radiator and was not covered under the power train warranty. We could not afford the 630 dollars that they wanted to charge us so we decided to have a known mechanic do the work. …”
