The 2000 MPV is a solid minivan platform when equipped with the 3.0L V6, but suffers from significant transmission cooling failures and upper engine problems on higher-mileage examples. The 2.5L V6 is less common and shares similar issues.
Transmission Oil Cooler Line Failure and External Cooler Corrosion
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Transmission fluid leaking from radiator area or frame-mounted external cooler, Pink fluid puddles under vehicle, Transmission slipping or delayed engagement after leak develops, Transmission overheating warning in hot weather or towing
Fix: Replace corroded hard lines and external cooler assembly. Often requires transmission flush if contamination occurred. 3-4 hours labor for lines and cooler; add 2 hours if full flush needed.
Estimated cost: $600-1,200
Hydraulic Valve Lifter Tick and Camshaft Wear
Common · medium severityTypical onset: 120,000-180,000 mi
Symptoms: Loud ticking or tapping from valve cover area, worse when cold, Ticking persists after warm-up despite fresh oil change, Check engine light with multiple misfire codes in severe cases, Loss of power on acceleration
Fix: Requires valve cover removal, lifter replacement, often camshaft inspection/replacement if lobes show wear. If caught early, lifters only: 4-5 hours. With camshaft work: 8-10 hours including timing chain access.
Estimated cost: $800-2,500
Head Gasket Failure (3.0L V6)
Occasional · high severityTypical onset: 130,000-200,000 mi
Symptoms: White smoke from exhaust on startup, Coolant loss with no visible external leaks, Milky oil on dipstick or oil cap, Overheating under load or persistent bubbles in overflow tank
Fix: Single head gasket jobs often lead to doing both banks due to labor overlap. Includes resurfacing heads, new timing components, water pump while apart. Single bank: 12-14 hours; both banks: 18-22 hours.
Estimated cost: $2,200-4,500
Flexplate Cracking (Automatic Transmission)
Occasional · medium severityTypical onset: 100,000-160,000 mi
Symptoms: Metallic rattling or knocking at idle in gear, Noise disappears in park or neutral, Vibration through floor during acceleration, Starter engagement grinding in extreme cases
Fix: Transmission must be dropped to access flexplate. Replace flexplate and inspect torque converter. 6-8 hours labor including R&R and alignment.
Estimated cost: $900-1,400
Transmission Mount Collapse
Common · low severityTypical onset: 90,000-140,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Excessive engine movement visible from engine bay during acceleration, Vibration through shifter or center console, Drivetrain shudder on takeoff
Fix: Replace rear transmission mount. Simple job requiring minimal disassembly. 1-1.5 hours labor.
Estimated cost: $180-320
Fuel Filter Clogging and Fuel Delivery Issues
Occasional · medium severitySymptoms: Hesitation or stumbling under acceleration, Difficulty starting after sitting overnight, Loss of power at highway speeds, Check engine light with lean fuel codes
Fix: In-line fuel filter located under vehicle near tank. Often neglected maintenance item; Mazda recommended 30k intervals but many go 60k+. 0.5-1 hour labor.
Estimated cost: $120-220
Decent buy under 100k miles with documented transmission cooling system maintenance; avoid high-mileage examples with valve noise or unknown service history.
