The 2025 eK Wagon is Mitsubishi's kei-car platform with 660cc 3-cylinder engines—minimal real-world data exists since it's current-year, but historical eK platform trends and the documented repair frequency point to timing chain wear, CVT cooler failures, and cylinder head issues on turbo models as primary concerns.
CVT Transmission Oil Cooler Failure
Common · high severityTypical onset: 50,000-90,000 mi
Symptoms: Transmission overheating warnings on dash, Shuddering or delayed engagement when hot, Pink or milky transmission fluid indicating coolant contamination, Loss of forward gears after sustained highway driving
Fix: Replace transmission oil cooler and flush entire CVT system; contamination cases require full CVT replacement. External cooler alone: 3-4 hours labor. Full CVT swap when coolant cross-contaminated: 8-12 hours.
Estimated cost: $800-1,200 cooler only, $3,500-5,500 if CVT replacement needed
Timing Chain Stretch and Lifter Noise (BR06 Turbo)
Occasional · high severityTypical onset: 70,000-110,000 mi
Symptoms: Rattling from engine on cold starts that persists 5-10 seconds, Check engine light with cam/crank correlation codes (P0016, P0017), Loss of power and rough idle under load, Metallic ticking that increases with RPM
Fix: Timing chain, guides, tensioner, and all hydraulic lifters replacement; turbo models show accelerated wear from oil coking. 10-14 hours labor due to cramped kei-car engine bay and head removal often required for lifter access.
Estimated cost: $2,800-4,200
Cylinder Head Gasket Failure (Turbo Models)
Occasional · high severityTypical onset: 80,000-130,000 mi
Symptoms: White smoke from exhaust on startup, Coolant loss with no visible leaks, Overheating under boost/load conditions, Bubbles in coolant reservoir when engine running, Rough idle and misfires on specific cylinder
Fix: Head gasket replacement with cylinder head machining; turbo BR06 runs high specific output (64hp/liter boosted) stressing gasket. Often find warped head requiring machine work. 12-16 hours labor including head R&R and resurfacing.
Estimated cost: $2,200-3,800
Transmission Mount Collapse
Common · medium severityTypical onset: 40,000-70,000 mi
Symptoms: Clunking when shifting from Park to Drive, Excessive vibration at idle in Drive, Visible engine/trans movement when revving in Park, Harsh engagement into reverse
Fix: Replace transmission mount; lightweight kei-car design uses softer mounts that fatigue quickly. 1.5-2 hours labor, straightforward access from underneath.
Estimated cost: $250-450
Harmonic Balancer Separation
Rare · high severityTypical onset: 90,000-140,000 mi
Symptoms: Severe vibration at all RPM ranges suddenly appearing, Squealing from serpentine belt area, Visible wobble of crankshaft pulley when idling, Check engine light with crank position sensor codes
Fix: Replace harmonic balancer before rubber ring completely separates; can damage crank snout or timing components if pulley comes off. 2-3 hours labor, must remove front bumper for access on kei-car packaging.
Estimated cost: $450-750
Camshaft Lobe Wear (Turbo High-Mileage)
Rare · high severityTypical onset: 120,000+ mi
Symptoms: Persistent lifter noise that doesn't quiet after warm-up, Loss of power particularly in mid-range RPM, Misfires on one or more cylinders, Metal particles in oil during changes
Fix: Camshaft and lifter replacement; turbo models with extended oil change intervals show accelerated wear. Requires cylinder head removal on BR06. 14-18 hours labor including head R&R and valve adjustment.
Estimated cost: $3,200-5,000
Buy naturally-aspirated only and budget for CVT cooler preemptive replacement at 60k miles; turbo models have too many expensive top-end issues for a disposable kei-car platform.
