MU-X RF (1st gen) inspection checklist

2013-2020 · 3 things to check before you buy, taken from this car's known problems.

This car

mediumEGR valve / intake clogging

Look for: Soot mixed with crankcase oil fumes clogs the EGR valve and coats the inlet manifold, narrowing it - causing poor starting, power loss, rough idle and worse economy. A stuck valve runs about $1500 to replace.

If you find it: Clean EGR and intake; fit a catch-can to slow buildup; replace the valve if seized.

From 80k+ km · ~$300-1500

mediumDPF soot loading on short trips

Look for: Used mainly for short city trips the DPF can't passively regenerate; soot builds and triggers limp mode, eventually needing forced regen, cleaning or replacement.

If you find it: Drive 80km/h+ for 20-30 minutes weekly to allow passive regen; clean/replace DPF if loaded.

Any (urban use) · ~$500-2500

mediumInjector wear

Look for: Common-rail injectors wear beyond ~150k km - rough idle, misfire, white smoke on startup, worse economy.

If you find it: Injector test and replacement; quality fuel and filtration extend life.

From 150k+ km · ~$1500-3000

3 minor things (low severity)

lowFront suspension / ball joints (off-road use)

Look for: Front ball joints and bushes wear with km and rough-road use.

If you find it: Replace worn components; wheel alignment after.

From 120k+ km · ~$300-800

lowBrake wear (towing / heavy use)

Look for: A loaded 7-seat wagon wears front brakes, especially towing.

If you find it: Quality pads/rotors; towing-spec pads for tow duty.

From 60k+ km · ~$300-700

lowCoastal rust / underbody

Look for: Coastal and beach-driven examples can show underbody and tailgate corrosion.

If you find it: Underbody inspection pre-purchase; wash down after beach use.
