mitsubishi challenger 2010 problems

The 2010 Mitsubishi Challenger (PB) is a tough old bus, but it’s not indestructible. Most gripes circle around the diesel drivetrain and the usual 4x4 wear-and-tear suspects. Here’s what owners and mechanics commonly report:

• Timing belt (and balance shaft belt) due roughly every 100,000 km or 5 years; skipped history is a gamble.
• EGR/intake carbon build-up causing rough running and sluggishness; cleaning and catch cans are popular fixes.
• Diesel injectors and fuel system (e.g., SCV) wear leading to hard starts, smoke, or limp mode.
• Cooling system stress when towing or working hard; watch for tired radiators and hoses.
• Front and rear suspension bushes, ball joints and shocks wearing out, bringing clunks and vague steering.
• 4x4 system niggles (vacuum/actuator issues) showing up as a flashing 4WD light or reluctant engagement.

A thorough pre-purchase inspection, confirmed timing-belt receipts, and a scan for stored fault codes will save headaches. Also check for outstanding recalls and evidence of heavy off-road abuse.
