My wife was driving on the interstate when the transmission failed and would no longer propel the vehicle. I have researched the problem and multiple people have had the same problem. I don't understand why no recall has been made. This is a very hazardous issue, especially if you are traveling on an interstate. She had to coast the car over and was rapidly loosing speed, a very dangerous situation. The problem is a faulty part in the transmission called a wave spring. In every f4a51 mitsubishi transmission, this has been an issue. The wave spring breaks, bypasses the filter, enters the pump gears and breaks the pump, ending in transmission failure. It is a costly repair, $1800-$2000. It is a faulty design, and a better aftermarket wave spring was eventually engineered. This should be a recall.

I have a '02 mitsubishi diamante and I have had problems out of the heater core leaking and now its affected my ecu (computer) I call the dealership and they want outrageous prices to fix or even check my car.. I think that since its a problem from the dealer they should recall these cars.. I know I will never buy another mitsubishi and I will never recommend them to a friend.. What can be done about this problem?

Heater core defective and leaked coolant underdash on to transmission ECM and neutral safety switch. Because of this very common manufacture defect I had to have my heater core, transmission ECM, neutral safety switch replace. And my transmission rebuild, none of which were warranted by the manufacture and were not cheap.

Tl*the contact owns a 2002 mitsubishi diamante. While driving 37 MPH, the vehicle jerked and the service engine warning indicator light illuminated. The contact attempted to accelerate and pull off the road, but when the engine revved, the vehicle moved approximately three feet and stopped. The vehicle had experienced this failure on two occasions. The dealer replaced the transmission at 20,000 miles. The contact also stated that the windshield was severely fogged. The dealer replaced the heater core because it was leaking antifreeze into the cooling system. The driver was nauseated for two weeks. The VIN was unknown. The current and failure mileages were 80,000.

January 12, 2005 one cold morning I noticed that the reverse gear did not go in as fast as it should it took like 1 minute to go into gear, when cold it would jolt before advancing in drive. Took it to the dealer, they did not find anything, so I picked up that same afternoon, next morning same problem. I took the car back on jan 19, left it over night and they found it took a couple of minutes to go into gear, therefore, they decided to look at the transmission, the car has been at the dealer since 1/20 thru 2/7, after several discussions they have told me it is the heating core dripping on top of the computer damaging the sensors, today 2/8 the car would not go into gear at all. I have had grease with the seat belts, they had to be changed at 3600 miles, the tires (eagle) had to be replaced at 18,000mies, the brakes starting acting up at 6000 miles, the steering started vibrating at 12,000 miles. Bottom line this car is a mess, sucks and mitsubishi does not want to be responsible for any of those problems, this is a big lemon!
