Van/Minivan
The 2006 Mazda MPV is the final model year of the second-generation MPV, a compact minivan that Mazda produced from 2000–2006. It slots below the Odyssey and Sienna in size and price, making it a practical choice for smaller families who want minivan convenience without the bulk. Powered by a 3.0L V6 and front-wheel drive, it offers a more car-like driving feel than most minivans of its era. The MPV was discontinued after 2006, which means parts availability has narrowed over time. Most mechanical pieces are still sourceable, but some body and trim components are getting harder to find. That said, the platform is generally solid and the V6 is a known, serviceable unit. For buyers in the Lake Geneva area, the MPV's lower ride height and FWD setup are worth noting — it handles packed snow reasonably well but isn't as capable as a taller AWD vehicle in deep accumulation. Rust from road salt is a real concern on any example this age.

Maintenance schedule
- 1 Every 5,000 miles or 6 months — do not stretch Engine oil and filter change
The VVT solenoids and passages are narrow; sludge from extended oil change intervals is the single biggest cause of expensive VVT and camshaft timing failures on this engine. Use a quality full-synthetic 5W-20.
- 2 Every 40,000–50,000 miles Automatic transmission fluid change
Mazda's spec ATF is critical. Using the wrong fluid causes shudder and premature clutch wear. If the fluid looks dark brown or smells burnt, change it immediately regardless of mileage.
- 3 Every 50,000 miles or 5 years Coolant flush
Old coolant loses its anti-corrosion inhibitors; the aluminum engine components and heater core are vulnerable. In Wisconsin, confirm freeze protection to at least -34°F before winter.
- 4 Every 60,000 miles Spark plugs
The rear bank of plugs on this transversely mounted V6 is awkward to access. Replacing on schedule prevents breakage from plugs that have been in too long. Use OEM-spec iridium or platinum plugs.
- 5 Every 2–3 years Brake fluid flush
Brake fluid is hygroscopic and absorbs moisture over time, lowering boiling point and promoting internal corrosion in the ABS modulator — especially relevant in humid Wisconsin summers and salty winters.
- 6 Every 12 months or at any sign of slow/jerky operation Sliding door rollers and track lubrication
Road grit and Wisconsin winter grime pack into the door tracks. Clean and lubricate the rollers, track, and cable guide annually to avoid the much more expensive motor and cable replacement.
- 7 Every fall before winter Underbody rust inspection and treatment
At this age, an annual inspection of brake lines, fuel lines, subframe, and rocker panels for rust is essential. Catching surface rust early and treating it is far cheaper than structural repairs or brake line replacement in an emergency.
- 8 Every fall Battery load test
A battery that passes a voltage test in summer can fail a cold-cranking load test. Sub-zero Lake Geneva winters will expose a weak battery fast. Replace any battery over 4–5 years old proactively.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$600 – $1,600
Fuel
At 18 mpg combined and ~12,000 miles/year, expect roughly $1,400–$1,700/year in fuel at current Wisconsin pump prices.
Insurance
Generally low — minivans carry some of the lowest insurance rates in any segment. Expect $900–$1,400/year for full coverage on a driver with a clean record, though the vehicle's age may push carriers toward liability-only.
The MPV has a low purchase price at this age, and routine maintenance is affordable at an independent shop. The real cost risk is deferred maintenance catching up — a neglected VVT system or transmission can cost more to fix than the vehicle is worth. Budget toward the higher end if the service history is unknown. Rust repair can push annual costs significantly higher on heavily corroded examples.
Seasonal care
Lake Geneva, WI Winter
- Load-test the battery every fall — the 3.0L V6 needs strong cold-cranking amps to start reliably at sub-zero Lake Geneva temps.
- Switch to a full-synthetic 5W-20 oil if not already using one; it flows faster at cold startup and protects the VVT system during those critical first seconds.
- Flush and refill washer fluid with a -20°F or colder rated fluid — diluted summer formula freezes in the reservoir and lines.
- Inspect and replace wiper blades before the first snowfall; consider winter-specific blades that shed ice buildup.
- Inspect all four brake lines and the proportioning valve area for rust-through — salt accelerates brake line corrosion on a vehicle this age.
- Clean and lubricate the sliding door tracks and seals before freezing temps arrive to prevent ice-seized doors.
Summer
- Check tire pressure monthly — every 10°F of temperature gain adds roughly 1 PSI, and overinflated tires wear unevenly and reduce grip.
- Have the A/C system inspected if cooling is weak; the compressor and expansion valve are the most likely failure points on this vintage.
- Check coolant freeze/boil-over protection — confirm it's good to at least 265°F on the high end to handle summer heat soak in stop-and-go traffic.
- Inspect the cabin air filter; pollen and debris accumulate through spring and reduce A/C efficiency significantly.
- Check the serpentine belt and tensioner — heat accelerates belt cracking and tensioner bearing wear, and a snapped belt leaves you stranded.
Comparable vehicles
2006 Honda
Odyssey
The Odyssey is the gold standard for used minivan reliability and has better long-term parts support, but it costs more and is larger. A well-maintained Odyssey will generally outlast an MPV.
2006 Toyota
Sienna
Similar price range used, top-tier reliability, and AWD was available — a major advantage for Wisconsin winters. Slightly larger and parts are easier to find than the MPV.
2006 Kia
Sedona
Priced similarly used, V6 powered, and parts are still widely available. Reliability is a step below Toyota/Honda but comparable to the MPV, often with more features per dollar.
2006 Dodge
Grand Caravan
Cheapest entry point in the segment used, and parts are everywhere. Reliability is noticeably lower, especially the transmission, but the Stow 'n Go seating is genuinely useful and repair costs are low due to volume.
