My front windshield was fogging up every time I used the heater and a smell of coolant inside my car--nasty film was left, found out it was a heater core problem. Sometimes the fog would take 20 minutes to clear up with defroster on highest settings. These problems are all over the internet with Mitsubishi Diamantes. I am surprised that these have never been recalled for safety reasons.

The black metal strip above the windshield came off while driving. All the plastic clips that attach the windshield to the strip were broken, and some were even missing upon inspection. I purchased the vehicle used from a dealership, and got a carfax report that showed the vehicle suffered no prior damage and had no prior accidents whatsoever.

Foggy window, antifreeze smell through vent, passenger side floor damp/wet. Was told by dealer that heatercore O-rings and heatercore possibly needs to be replaced. Looking for alternative solution to resolve the problem.

I own a 2002 Mitsubishi Diamante car, I bought this car in 02 since the 1st day I bought the car there was problems. The computer in the car went crazy my check engine light, ,cruise control, anti lock brake, tcl light all started flashing. I took the car back to the dealer & they replaced the computer but it didn't work they put 3 computers in since then, these lights are still on till this day. In 06 my trans blew I took the car back to the dealer they replaced my trans the car still doesn't ride right. My A/C turns on but nothing comes out sometimes. In the winter the inside of my car becomes a fog all over my windows and it wont stop fogging up. A smell is coming out of my vents like a coffee smell & im inhaling this smell whenever im in the car I have to go to a doctor to get checked out to see if I have health issues.my sun roof leaks when it rains, I took my car back to the dealer to have all these issues fixed but they never did I purchased the car in 02 the warranty lasted 02-05 B/C that is when my warranty expired. When I call they tell me I have to pay out of pocket B/C the warranty expired. This isn't fair to any Mitsubishi owner I shouldn't have to pay to have my car fixed now after the warranty when all the same problems have been recurring since I purchased the car and they never fixed it to begin with. I can understand if I was the only person with these problems I decided to search the internet to see if anyone else owned my make and model of my car to see if they had similar problems sure enough I came across a website called www.carsurvey.org/viewcomments_review_76426.html there's over 50 people with the same problems I have with my car.Mitsubishi should fix these problems and stand by there cars. I called corporate headquarters today & was told there's nothing they can do B/C its out of warranty.
