My 2011 Outlander Sport died last week at 40k miles. 3k miles since last synthetic oil change. No warning signs beforehand. Went to start up, fired for couple of seconds then died. Wouldn't start again. No strange noises or banging, sounded like the engine wasn't even turning over. Assumed it was a starter issue.

Towed to the dealer, who says upon inspection I have no/very little compression in all 4 cylinders. They won't speculate on what happened. Waiting on teardown authorization from Mitsubishi.

This sounds vey strange to me as all service is up to date. Engine was running great prio. No oil consumption, no smoke, no rough running or idling, no strange noises, fuel consumption and power were normal. She ran like new before this.

Any insights our known issues from the community? Other than stretched timing chains I can't seem to find anything on this motor or anything exactly like my scenario. Even the stretched timing chains seemed to give indication that something was wrong first. I had nothing. Ran great one day, dead the next.

Any thoughts would be appreciated.

 

That sounds strange. What size motor was in there? So what was the outcome? Did Mitsubishi replace the motor?
