Hello, I bought a used Eclipse Cross 4wd 1.6 fuel with 8000 km and with 7 months of life directly from the importer Mitzubishi Italy. After a few weeks I found a problem on the delivery. I explain better....Up to 2000 rpm the car revs up too much but it doesn't click as it should. In short, up to 2000 rpm it's as if the clutch was slipping. Then once the critical threshold of revs is exceeded, the car starts like a rocket. Two of the official dealers I spoke to told me that it is not possible to fix it with their electronic diagnostic tools, also to avoid voiding the warranty. Can you give me some advice on this issue? Thanks in advance to everyone.
