I have been in correspondence with Mitsubishi Motors Australia Limited (MMAL), in regards to the engine failures on the MN. As MMAL are not particularly forthcoming with info, perhaps it's time we showed them the extent of the concern amongst the Triton community. I have prepared a form letter so that you can copy-and-paste the text into an email, which should be sent to; customerrelations@mmal.com.au
Please send this to them as often as you feel the level of concern warrants

We all acknowledge that this issue exists, but the scope is completely unknown. In order to avoid another beat-up on this topic, perhaps this thread could be locked for posting and a separate thread for responses from MMAL could be started? It will be important to gather these responses for future action.
The text is below, please feel free to add your own comments/complaints to the letter when you email MMAL.
Dear Mitsubishi Motors Australia Limited,
As the owner of an MN Triton, I am concerned about the well documented engine failures due overheating. Service campaign 020116 was supposed to partially address this issue, however a number of vehicles have subsequently experienced engine failures after this test. Some vehicles are on their third engine as a result of the overheating.
Many failures have been reported on the internet, including on the NewTritonNet forum, which has a membership of over 23,000. There is a thread devoted to this topic, with nearly 1600 posts.
MMAL have not released any information as to the percentage of Tritons that have experienced engine failures, and have not been forthcoming with any information that will shed any light on the subject. This is leading to a large amount of uncertainty and is of great concern to the owners.
Most importantly, many people have lost faith in their vehicle, and are unwilling to risk taking holidays or trips, out of the fear that they will be stranded far from home. Clearly, this is unacceptable as no-one sets out to buy a vehicle that they can’t trust to be reliable. This well-founded lack of trust impacts on the enjoyment of ownership, and casts a significant shadow of doubt over both the MN Triton and Mitsubishi as a brand.
More significantly, as the MN starts to go out of the warranty period, many people are justifiably concerned that they will be lumbered with extensive repairs out of warranty, and there is a growing suspicion that MMAL have designed the service campaign solely to protect their interests, and de-rated the engines in order to get the vehicles through the warranty period prior to failure. A number of independent tests have shown a difference between the operation of the engine pre and post campaign ECU update.
I expect MMAL to address these concerns with an open exchange of information, detailing;
1. What percentage of MN Tritons sold in Australia have experienced engine failures.
2. The total number of vehicles that have had engine failures.
3. What changes were made to the ECU program during the campaign.
4. How MMAL intends to support people if engine failures due to this issue occur outside of warranty.
5. How MMAL intends to prove to owners that their vehicle is not affected by this issue.
None of these requests are unreasonable, especially given the damage done to the consumer confidence and resale value of the MN Triton as a result of a lack of information from MMAL.
In anticipation of your speedy reply,
