Nissan Primera: CVT stalling, shuddering and refusing to change ratio

The CVT in the P12 Primera has a poor record and owners report a consistent set of symptoms: the engine stalling as the car slows towards a roundabout or intersection, shuddering while driving, and in the worst cases the transmission stuck in a single low ratio and refusing to change at all. The underlying causes are the familiar CVT ones — degraded fluid, belt and pulley wear, and control faults — but on a car of this age and value the arithmetic is unforgiving: a replacement unit costs more than many P12s are worth. That makes a proper test drive the difference between buying a usable car and buying a write-off, and the stalling symptom in particular is one you will only find by driving it the way you actually drive.

• Engine stalling as the car slows to a stop or towards a roundabout
• Shudder or vibration while driving at steady speed
• Revs rising without the car speeding up to match
• Transmission stuck in one ratio, or refusing to pull away properly
• Whine or drone that rises and falls with road speed

Drive it the way this fault shows itself, which is in ordinary town driving rather than on the open road. Approach several roundabouts and intersections and slow right down to walking pace without stopping, then pull away again — the stalling owners describe happens exactly there, and a gentle motorway run will never find it. Hold a light, steady throttle at 40 to 60 km/h and feel through the floor and the seat for a shudder. Accelerate firmly once and watch that the revs rise and the speed builds with them rather than the engine flaring on its own. Note whether the car pulls away cleanly from every stop or hesitates. Listen for a whine or drone that tracks road speed. Ask when the CVT fluid was last changed and ask to see the invoice — many owners believe it is sealed for life, and on a car of this age that answer usually means never. Ask whether it has ever stalled or been stuck in gear. If a workshop inspection is possible: have the transmission fault memory read before you agree a price.

$400 to $5,000 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.

• “Has the CVT fluid ever been changed, and at what mileage?”
• “Has the engine ever stalled as you slowed down?”
• “Has the transmission ever got stuck or refused to change?”

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.
