The best information I have on the engine failure is user error, I had been driving for almost a year, but got my liscesnse about a month ago and was loving pushing the little motor to it's limits, I was on the highway, shifting from redline in 3rd gear to 4th, missed and went into 2nd, the engine went up to about 8000rpm. When i got home it started to sputter when idling, it sounded misfires. We took it up to our local mitsu dealer and it took them 2 weeks to find the cause, they had changed everything from the oil, spark plugs, cluth fluid, then they figured out the exaust manifold was blown, they attempted to fix the motor, it didn't work out. So then they ordered a new long block, got that installed and gave it back to me, I've taken better care of it this time around
