Almost three weeks later and it appears I am now just at the start of this journey! I got a call a few days ago from the Fresno Mitsubishi service desk - they said that they finally found the problem. They said that in going back and forth with the national Mitsu center they have determined that it is my onboard charger that is the problem. That sort of makes sense, as all the clicking noises that usually accompany plugging in the car did not happen when I last plugged it in. Two things that make we worried/very frustrated. He said that I had 67,000 miles on the car. Hmmm. I have 17,000 miles on it. That took him aback, as I think he was going to try to get out of some of the warranty - he claimed that the charger unit has a 5 year, 50,000 mile warranty. I thought it was 8 year, 80,000 mile on everything related to the battery/electric system. Anyway, he took his words back and said he would double check the mileage. The second thing he said, however, was that there were no spares of this part in the U.S. so he would have to order the part from Japan and 'that will take several months.'
Huh??? If I were quick on the reply I should have told him there was this new invention called the airplane that delivers things faster than a boat. Or that just a few months ago I ordered a transmission from Holland for a VW and it was here in 72 hours. But I was just flabbergasted. There is no plan for a car to replace mine while it sits at the dealer for months. I asked him to text me when he had the part ordered and to give me an estimate on the arrival date - he said he would but has not; it's been 3 days now since we talked.
Fortunately I have a spare car so I can survive but if I did not I would not be thinking about keeping my Mitsu right now! Before this I had the feeling that dealers are quite incompetent - this only confirmed and clarified this feeling. It took three weeks to simply identify the problem and now it will take several months to get the part. I will likely go in and talk to the supervisor.
