Equipment: other: owners/service/other manual
- What is wrong
- Certain sport utility and passenger vehicles fail to comply with federal motor vehicle safety standard no. 225, "child restraint anchorage systems." the owner's manual does not contain a step-by-step description for headrest adjustment when installing a child restraint system (crs) tether strap.

Recall number 04V067000 · Recall details
Electrical system: wiring: front underhood
- What is wrong
- On certain passenger vehicles, the main under hood electrical wiring harness may have insufficient clearance between the engine control harness and the exhaust heat shield. As a result, the harness could come in contact with the heat shield, which could result in melting of the harness insulation.
- Risk
- The melting of the harness insulation could result in grounding of the crank angle sensor wiring, causing the engine to run erratically or stop suddenly, increasing the risk of a crash.
- Remedy
- Dealers will inspect the harness for damage and, if none is evident, will tie the harness back to prevent the harness from ever coming into contact with the heat shield. Any harness that shows evidence of damage will be repaired as necessary and then tied back to prevent future damage. Owner notification began may 13, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mitsubishi at 1‑800‑222‑0037.

What 2002 Mitsubishi Diamante owners say
Most recent owner complaints, unedited.
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.

The heater core is an extremely dangerous problem. The windows in the car fog up so bad I couldnt drive the car...had to pull over and wipe the windows down. But the thing is...I didnt know what the problems was...until I realized the windows werent just being fogged by the cold, ect it was a toxic mist from a heater core problem...I pulled over 2 times because I got sick...I noticed a mist coming out of the vents....so all in all I called mitsubishi and they refuse to do anything about this.this heater core problem can lead to accidents, sickness, and othe expensive problems in the car! The fumes are extremely toxic!!! There are 1000's of complaints and blogs about this problem...I'm sure there are 100,000+ complaints abpout this problem. And mitsubishi refuses to help or do anything about this. I told them, is this gonna take a fatal accident for them to do something?" they replied, "im not answering that!" I told them that they should have recalled this problem. They replied, "sorry but your warranty is up we can't do nothing about it." this heater core problems leads to faulty transmission problems, electrical problems, hazerdous problems, sickness, interior of the car can be ruined because anitfreeze leaks through the dash board...where mitsubishi placed the heater core. Made no sense to place a heater core above the electrical component of the transmission. They really messed up here and will not do anything about this. I think that the media should get involved because they probably wont do anything about if someone doesnt speak up!

Just like everyone else with a 2002 mitsubishi diamante, I have had heater core problems. Antifreeze leaking/smell and windows fogging up. Cost to repair exceeds $1000. If every one of these vehicles has this same issue, why has it never been recalled? And why does mitsubishi get away with all cars having this defect? And why has this investigation not resulted in action? Is there another agency that can get recall action from mitsubishi?
Mitsubishi diamante 2002 has faulty o-rings and is widely publicized to cause major heater core problems and anti-freeze leakage.
