Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I got into my car to start and it would turn over but not start. After replacing the fuel pump, checking all the fuses and relays, still the same problem. The wire harness fuse block that sits inside the drivers foot well has been corroded by water from a leak in the fire wall. This is a very common problem that even goes back to the previous generation , evo vii, and wasn't fixed for the following generation, evo ix.”

“I own a 2003 Mitsubishi Lancer Evolution that was purchased brand new from the dealership in the middle of 2003. The car had run fine until about may 12th of this year. The car started performing oddly. The turbo and engine would not provide full power at random times while driving. I was informed by mechanics that it could possibly be a vacuum line leak or hose leak. Acting on their advice, I purchased from the dealership replacement factory vacuum hoses and replaced them on the car. This did not fix the problem. …”

“Upon inspection of the undercarriage in the rear, areas of severe corrosion has developed underneath the rear on the aluminum subframe bar that holds the rear differential and other suspension components in place such as the rear differential & lateral control bars that can surely compromise the cars ability to drive if unnoticed. Additionally the fuel lines along the gas tank, as well surrounding surfaces on the driver side rear, have developed noticeable corrosion as well that is also proving to be a large area of concern. …”
