The 2001 MPV is best known for catastrophic transmission failures on V6 models and oil consumption issues on the 3.0L engine. The 4-cylinder is rare but more reliable; most owners face expensive drivetrain repairs before 150,000 miles.
Automatic Transmission Failure (V6 Models)
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Harsh shifting between 2nd and 3rd gear, Delayed engagement from Park to Drive, Transmission slipping under load or complete loss of forward gears, Burnt transmission fluid smell and dark fluid on dipstick
Fix: Internal clutch pack and valve body failure require rebuild or replacement. Rebuild takes 12-16 hours; used transmission swap 8-10 hours. Oil cooler replacement mandatory during any transmission work to prevent repeat failure.
Estimated cost: $2,800-4,500
3.0L V6 Oil Consumption and Valve Train Wear
Common · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Burning 1+ quart of oil every 1,000 miles, Blue smoke from exhaust on cold starts or acceleration, Valve lifter ticking noise especially when cold, Check Engine Light with lean codes or misfires
Fix: Worn piston rings and valve stem seals allow oil into combustion chambers. Proper repair requires engine removal, cylinder head work, and often ring replacement. Lifter noise may need camshaft and lifter replacement. Total job 18-25 hours.
Estimated cost: $3,500-6,000
Rear Differential Mount and Bushing Failure
Occasional · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Clunking sound from rear when accelerating or shifting, Vibration through floor at highway speeds, Visible differential movement when rocking vehicle in gear, Excessive driveshaft angle causing CV joint wear
Fix: Rubber differential mount deteriorates and allows excessive movement. Requires rear subframe support and differential repositioning. Often done with transmission mount replacement. 3-5 hours labor.
Estimated cost: $400-800
Flexplate Cracking (V6 Models)
Occasional · high severity
Typical onset: 100,000-160,000 mi
Symptoms: Metallic rattling or knocking at startup that disappears when warm, Grinding or scraping noise during cranking, Check Engine Light with crankshaft position sensor codes, No-start condition if cracks progress to complete failure
Fix: Flexplate develops stress cracks near torque converter bolt holes. Requires transmission removal to access. Always inspect starter ring gear and replace torque converter bolts. 8-10 hours labor.
Estimated cost: $900-1,500
Power Steering Rack Leaks
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Power steering fluid puddles under front center of vehicle, Whining or groaning noise when turning at low speeds, Stiff steering especially when cold, Rapid power steering fluid consumption
Fix: Inner tie rod seals and rack seals fail. Rack replacement requires front subframe drop for proper access. Many mechanics quote rack only but find additional pump wear. 4-6 hours labor for rack.
Estimated cost: $800-1,400
EGR Valve and Intake Manifold Carbon Buildup
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Rough idle or engine stalling at stoplights, Check Engine Light with EGR flow codes P0401, Hesitation or stumble during light acceleration, Failed emissions testing
Fix: EGR passages and intake plenum clog with carbon deposits. Requires intake manifold removal, manual cleaning, and EGR valve replacement. Preventable with fuel system cleaning every 30K miles. 3-4 hours labor.
Estimated cost: $350-650
Owner tips
Change transmission fluid every 30,000 miles with genuine Mazda ATF-M5 or equivalent — this is critical for extending transmission life beyond 100K
Monitor oil consumption closely on 3.0L V6 after 80,000 miles; keeping oil topped off prevents catastrophic bearing damage
Replace transmission oil cooler lines preemptively at 100K miles — $200 job that prevents transmission contamination
Inspect rear differential mount annually after 60K miles; catching it early prevents driveshaft and CV joint damage
Avoid unless you find a well-maintained low-mileage example under $3,000 — budget for transmission work on any V6, and consider the 4-cylinder if you can find one.

ON CERTAIN MINIVANS EQUIPPED WITH CRUISE CONTROL, THE CRUISE CONTROL ACTUATOR CABLE MAY BE BROKEN DUE TO INSUFFICIENT STRENGTH (GROUP 1). ALSO INCLUDED ARE CERTAIN 2000-2001 MINIVANS EQUIPPED WITH CRUISE CONTROL BUILT BETWEEN MARCH 31, 1999 AND MARCH 31, 2001, THAT HAVE HAD THE CRUISE CONTROL REPAIRED AND POSSIBLY HAD A DEFECTIVE CABLE INSTALLED DURING THAT REPAIR (GROUP 2).
Consequence: IT IS POSSIBLE THAT THE BROKEN ACTUATOR CABLE MAY BE OUT OF POSITION AND COULD INTERFERE WITH THE OPERATION OF THE ACCELERATOR CABLE, PREVENTING A DECREASE IN ENGINE SPEED WHILE DRIVING, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE ACTUATOR CABLE. OWNER NOTIFICATION FOR VEHICLES INVOLVED IN GROUP 1 BEGAN ON JULY 7, 2004. OWNER NOTIFICATION FOR VEHICLES INVOLVED IN GROUP 2 BEGAN ON SEPTEMBER 10, 2004. OWNERS SHOULD CONTACT MAZDA AT 1-800-222-5500.
