Maserati GranCabrio (Gen 2) Common Problems & Reliability
The second-generation Maserati GranCabrio debuted in the UK in 2024 as the open-top sibling to the new GranTurismo coupé, continuing Maserati's illustrious tradition of glamorous four-seat drop-tops. Constructed on the same lightweight aluminium-rich platform, the GranCabrio utilizes a high-tech multi-layer fabric soft-top that deploys or stows electro-hydraulically in just 14 seconds at speeds up to 31mph. Power comes from the potent 550bhp 3.0-litre twin-turbo Nettuno V6 in flagship Trofeo specification, driving all four wheels via an 8-speed ZF automatic gearbox, with the revolutionary all-electric GranCabrio Folgore providing 761bhp of roof-down EV propulsion. It offers genuine seating capacity for four adults and a neck-warmer system built into the front headrests for year-round British open-air touring, balanced against limited boot luggage space with the roof retracted.

Most Common Maserati GranCabrio (Gen 2) Faults & Repair Costs
Convertible Soft-Top Latch Sensor and Partition Alignment Warnings
On early GranCabrio models, owners can experience intermittent convertible top malfunction alerts on the digital instrument cluster. These are usually caused by sensitive microswitches in the boot luggage separator partition or header rail latches detecting misalignment, preventing the folding sequence from initiating or completing properly. Adjusting the switch tolerances and updating the convertible roof control module firmware resolves the fault.
Convertible top operation paused warning on dashboard display, Roof halts mid-cycle or refuses to unlatch from front windshield header, Boot luggage partition sensor warning chime when operating roof switch
- Operate roof from open to closed positions multiple times during viewing
- Ensure the boot luggage partition clicks solidly into its retaining brackets
- Check dealer service records for soft-top calibration and microswitch alignment
Quiescent Battery Drain from Multiple Control Modules
Modern Maseratis carry dozens of networked microprocessors, high-voltage radar sensors, and telematics modules that draw continuous parasitic current when the car is parked. If left idle for more than a fortnight without a battery conditioner, the 12V starter battery voltage drops below threshold, triggering spurious electronic error warnings upon startup across the electronic differential, ABS, and comfort systems.
Slow engine turnover or battery protection active warning on start, Multiple cascading dashboard fault messages that clear after a short drive, Keyless entry door handles fail to respond to proximity touch
- Check condition and age of the factory 12V AGM auxiliary battery
- Verify that a magnetic battery conditioner port and charging kit are included
- Scan vehicle electronics for low-voltage historical fault codes
Convertible Roof Touchscreen Control and Screen Heat
The Gen 2 GranCabrio's fabric roof is raised and lowered by swiping the lower central touchscreen instead of a dedicated button. Auto Express noted the need to make a dirty great big swipe mark on the lower touchscreen to put the roof up and down, and raised question marks over GranCabrio build quality. Parkers found the lower screen, which also runs the climate controls, can get hot to the touch with the roof lowered, and that roof control is buried in a sub-menu. Touching the screen while driving to operate the roof distracts from the road, and a hot display in summer suggests poor thermal management of the lower screen. There is no physical roof switch as a fallback; the likely fix is a dealer software update or roof-control menu recalibration, normally at little or no cost.
Roof can only be opened or closed via a swipe on the lower touchscreen, Lower touchscreen feels hot to the touch with the roof down in sunny weather, Roof control is buried in a sub-menu with no dedicated button, Screen must be touched while driving to operate the roof
- Operate the roof through full open and close cycles using the touchscreen
- Check the lower screen temperature with the roof lowered on a warm day
- Confirm roof and latch sensor warnings are clear on the digital cluster
- Ask the dealer about the latest infotainment and roof-control software version
Buying a used Maserati GranCabrio (Gen 2)? Always check for hidden finance and write-off history.
Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.
