Nissan Lafesta: MR20DE early-production CVT premature internal failure

MR20DE early-production CVT premature internal failure is a common transmission fault on the Nissan Lafesta on the 2004–2009 cars, and we rate it critical. Putting it right costs $3,500 to $6,500 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 11 documented faults on the Nissan Lafesta.

What you are looking at

No photograph available

We do not hold a verified photograph of the CVT belt and pulleys yet. We would rather show none than show a picture of a different part.

What goes wrong

Early B30 Lafesta units paired with the MR20DE and Jatco CVT7 (RE0F10A) suffer from premature CVT failure, particularly in JDM examples imported to NZ/AU. The CVT's primary and secondary pulleys develop wear on the push-belt contact surfaces, and the hydraulic pump deteriorates, leading to slipping, juddering, and eventually complete loss of drive. Nissan issued internal guidance on this transmission pairing, and replacement units were supplied under warranty in Japan. NZ imports that arrive post-warranty are fully exposed to out-of-pocket CVT replacement costs.

What you would notice

Harsh shuddering or vibration under light to moderate acceleration, particularly at 40-80km/h
Slipping sensation — engine revs rise without corresponding vehicle speed increase
Delayed engagement when shifting from Park to Drive
CVT warning light or check engine light with Jatco-specific transmission codes

How to check it

Where to look. Transmission tunnel, Jatco CVT7 unit directly behind the engine

Test drive with attention to the 40-80km/h acceleration zone — any shudder or slip is a red flag.
Check CVT fluid condition via the dipstick or fill plug (should be pinkish, not brown or burnt-smelling).
Verify fluid service history — Nissan NS-2 or NS-3 fluid and the interval it was changed at.
Request a CVT fluid scan via OBD for stored transmission codes.
Check whether a JDM import history shows any prior CVT work under Japanese warranty.

Parts involved: CVT belt and pulleys.

What it costs to put right

$3,500 to $6,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the CVT fluid ever been changed — what fluid was used and at what mileage?”
“Does the car shudder or hesitate during acceleration, especially at highway speeds?”
“Has any transmission warning light been on, even briefly?”

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Nissan Lafesta buyer questions

Is mr20de early-production cvt premature internal failure serious on a Nissan Lafesta?

We rate it critical and common on the Nissan Lafesta. Early B30 Lafesta units paired with the MR20DE and Jatco CVT7 (RE0F10A) suffer from premature CVT failure, particularly in JDM examples imported to NZ/AU. The CVT's primary and secondary pulleys develop wear on the push-belt contact surfaces, and the hydraulic pump deteriorates, leading to slipping, juddering, and eventually complete loss of drive. Nissan issued internal guidance on this transmission pairing, and replacement units were supplied under warranty in Japan. NZ imports that arrive post-warranty are fully exposed to out-of-pocket CVT replacement costs.

How much does it cost to fix on a Nissan Lafesta?

$3,500 to $6,500 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 Nissan Lafesta years are affected?

Our research records this fault on the 2004–2009 Nissan Lafesta. 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.

How do I check for it before I buy?

Test drive with attention to the 40-80km/h acceleration zone — any shudder or slip is a red flag. Check CVT fluid condition via the dipstick or fill plug (should be pinkish, not brown or burnt-smelling). Verify fluid service history — Nissan NS-2 or NS-3 fluid and the interval it was changed at.
