1 Fuel Injection problem of the 2002 Mitsubishi Diamante

Failure Date: 12/28/2005

I purchased a used 2002 Mitsubishi Diamante in August 2005. The car had 45,000 miles on it. In October when I started to use the heater I could smell an unusual smell inside the car. In January of 2006 my brother rode in the car and told me the smell was anti-freeze. I went on the internet and instantly found out that this model car has a problem with the heater core o-rings failing. The smell in the car got real bad real quick and I had to have the leaking o-rings repaired. I would get sick from the smell and had no choice but to have it fixed. I brought the car to a Mitsubishi dealer and had the repair done for $650. The car had 48,000 miles on it when the repair was made. That is alot of money for problem that Mitsubishi should have corrected.
