Mitsubishi Outlander Engine Mount: Specs, Fitment & Common Faults

Mitsubishi Outlander Engine Mount: What It Does
Engine mounts secure the engine and transmission to the chassis while absorbing vibration and movement, preventing that vibration from transferring directly into the cabin. Most versions of the Outlander use several mounts working together — typically at least one on each side of the engine plus a torque mount — and a single failed mount can throw off the whole assembly's balance.

A Genuinely Alarming, Real Pricing Discrepancy Worth Knowing About on the PHEV — Mitsubishi Outlander Engine Mount
If you're facing a clunk from underneath the car on the plug-in hybrid when moving off or changing direction, this is genuinely worth knowing before agreeing to a repair quote: the rear motor mount bush, the front-most of the three mounts, is documented as the first to fail, and it's a genuinely easy DIY job taking less than 20 minutes once you're under the car. One documented case saw a garage quote £600 for what they described as a "differential mounting" part — but the actual replacement bush needed is available from an aftermarket brand for under £24 including delivery, or as a genuine Mitsubishi part for somewhere between £50 and £100. It's genuinely worth getting a second quote or sourcing the part yourself if you're facing a similarly high quote for what sounds like this specific job.
It's also genuinely worth knowing a useful diagnostic distinction: a clunk specifically when moving off or selecting drive typically points toward the rear motor mount, but a separate, deep vibration or resonance that only appears when accelerating at higher speed can have an entirely unrelated cause — in one documented case, this turned out to be binding front brake calipers rather than anything related to the motor mounts at all. Worth being careful not to assume every noise or vibration issue shares the same root cause, even if they seem to have appeared around the same time.
