Starter clicks, doesn't turn engine. Tried rotating engine, engine will not turn past a certain angle. Removed spark plugs for cylinder inspection. 1,2, and 3 ok. Cylinder 4 spark plug extremely difficult to remove. Ground strap has been impacted by debris. Borescope inspection shows two broken off exhaust valves laying on the piston. Valve cover removed to inspect timing chain and sprokets. Chain and sprokets are intact. Engine reassembled besides cylinder 4 spark plug and coil pack.

This 2017 outlander has had issues with the tire rod multiple times. It needed to be fixed approx every three months and the tires needed constant changing as well. This vehicle had a timing chain issue which left me stranded in the middle of the high way. the power stopped, the car started to jerk back and forth and it would power off. We had to get this car towed to three seperate mechanics as no one would work on a mitsubishi and I was told it was the timing chain with possible engine damage. Prio to all of this happening the radio and electrical system would freeze or automatically turn off and on, it never resolved and blue tooth was rarely able to be used.

My greatest concern is the engine stalling while driving, new battery draining so quickly , the vehicle shaking while idle then shuts off. I cannot understand how my vehicle was not added to the engine stall recall even with these problems replicating what Mitsubishi identifies in there past recalls. This is very dangerous because macanics or diagnostic computers cannot identify problems with the car but after driving it for a good while or maybe a few hours the car could just shut off in the middle of no where in a highway which has already happened to me endangering me and my family. I write to NHTSA today so that my vehicle as urgently as possible can be included in a investigation for this vehicle to be included in Mitsubishi's recall.
