Ferrari 812 Superfast / GTS

The 812 is generally strong but not immune from electrical faults, with reports of warning-light clusters, camera and infotainment malfunctions and occasional major electrical system warnings that can strand the car. Some issues clear with a restart or software update, while others need dealer diagnosis. Porous intake-manifold castings and solenoid cover plate leaks have also been blamed for fluid leaks. Test every electronic function and scan for stored fault codes.

Like other modern Ferraris, the 812 is sensitive to battery voltage, and cars left standing for days can develop battery-related faults and obscure error codes. A quality trickle charger is essential if the car is not driven regularly, and lithium battery replacement is costly. Check battery age and health, ensure a conditioner is used, and test voltage after an overnight stand.

The 7-speed Getrag dual-clutch gearbox shares architecture with the 458's unit and can suffer speed-sensor failures, causing loss of even or odd gears with transmission warnings, and pump spindle seal leaks that let hydraulic fluid mix with the oil. Clutch wear can also run ahead of mileage. Dealer rebuilds cost several thousand pounds, so verify the gearbox shifts cleanly when cold and warm, and check whether any sensor or seal work has been done.
