Mitsubishi ASX: CVT Belt Abrasion and Catastrophic Pulley Failure
CVT Belt Abrasion and Catastrophic Pulley Failure is a common transmission fault on the Mitsubishi ASX on the 2010 onward cars, and we rate it critical. Putting it right costs $4,500 to $9,000 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 26 documented faults on the Mitsubishi ASX.

What goes wrong
When the CVT hydraulic judder fault (above) is left unaddressed, ongoing belt slippage generates abrasion powder that contaminates the hydraulic pressure circuit and rapidly wears the steel push-belt and pulley contact surfaces. Mitsubishi TSB-20-23-001 explicitly states that continued driving under shudder conditions causes belt slip and abrasion powder contamination leading to CVT warning illumination with codes P0776, P0730, or P084A. The end-stage failure is complete CVT seizure or loss of drive, requiring full transmission replacement.
What you would notice
- CVT warning light or flashing D-position indicator on dashboard
- Loss of acceleration or engine revs rising without corresponding speed increase
- Transmission entering limp mode, limiting speed to approximately 40–60 km/h
- Metallic shimmer or grey particulate in CVT fluid on inspection
- Total loss of drive with engine running in severe cases
How to check it
Where to look. CVT unit under vehicle, accessible from underneath near transmission crossmember
Road test for any shudder; a clean test drive without judder with recently serviced fluid is minimum reassurance. Budget for CVT replacement if fluid is overdue and shudder is present. If a workshop inspection is possible: Drop the CVT fluid into a white container and examine for metallic shimmer or grey sludge — contamination indicates internal belt wear already underway.
What it costs to put right
$4,500 to $9,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has this vehicle ever had a CVT replacement or major transmission repair?”
- “Is the seller aware of any shudder, hesitation, or warning lights in the transmission?”
- “Can a pre-purchase inspection with a full fluid drop and DTC scan be arranged?”

Mitsubishi ASX buyer questions
Is cvt belt abrasion and catastrophic pulley failure serious on a Mitsubishi ASX?
We rate it critical and common on the Mitsubishi ASX. When the CVT hydraulic judder fault (above) is left unaddressed, ongoing belt slippage generates abrasion powder that contaminates the hydraulic pressure circuit and rapidly wears the steel push-belt and pulley contact surfaces. Mitsubishi TSB-20-23-001 explicitly states that continued driving under shudder conditions causes belt slip and abrasion powder contamination leading to CVT warning illumination with codes P0776, P0730, or P084A. The end-stage failure is complete CVT seizure or loss of drive, requiring full transmission replacement.
How much does it cost to fix on a Mitsubishi ASX?
$4,500 to $9,000 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Mitsubishi ASX years are affected?
Our research records this fault on the 2010 onward Mitsubishi ASX. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
