We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

The Portofino and Portofino M inherited the California's folding hardtop and some of its habits. Owners report the roof stopping mid-cycle, refusing to lock, and the dash putting up 'complete roof cycle' and 'roof failure' messages with a continuous warning beep, and dealers have traced the recurring cause to Hall-effect position sensors that fail or drift out of alignment. It is more likely on a roof that is used constantly or operated in cold weather, and on some cars the problem has come back after repair. Cycle it several times yourself and treat any hesitation as a fault to be priced.

What you would notice

  • 'Roof failure' or 'complete roof cycle' message with a continuous beep
  • Roof stopping part-way or not locking at the end of the cycle
  • Roof working only after several attempts
  • Interior trim pieces around the roof coming loose

How to check it

Where to look. Roof position sensors and locking mechanism on the roof frame and header rail; roof control unit

With the engine running on level ground, cycle the roof fully open and closed at least twice and watch it complete each time without pausing, without a chime and with the header locking cleanly at the windscreen. Try it a third time after the drive. Look at the trim around the roof mechanism for loose pieces. Ask whether the roof has ever shown a warning, whether sensors have been replaced or realigned, and whether the problem came back.

What it costs to put right

$800 to $6,000 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.

Ask the seller

  • “Has the roof ever shown a failure warning, and what was done?”
  • “Have any roof sensors been replaced or realigned?”
