Ferrari 812 Superfast / GTS Common Problems & Reliability
The Ferrari 812 Superfast was sold in the UK from 2017 to 2024 as Ferrari's last naturally aspirated front-engined V12 grand tourer, with a 6.5-litre V12 producing 800bhp and a seven-speed dual-clutch gearbox; the 812 GTS convertible arrived in 2019. It is a very usable daily supercar, but modern-Ferrari sensitivities apply: battery care, electronic warning lights and DCT transmission wear are the key checks for a used buyer, together with confirming all recall campaigns are complete.

Most Common Ferrari 812 Superfast / GTS Faults & Repair Costs
Electrical faults and warning-light clusters
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.

- Test every electronic function during the test drive
- Scan for stored fault codes and warning-light history
- Check for fluid leaks around the intake manifold and solenoid cover plate
Battery-related faults on cars that stand
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.

- Check battery age and health with a multimeter or diagnostic tool
- Confirm a battery conditioner is used when the car stands
- Test voltage after an overnight stand and look for warning lights
DCT gearbox sensor, seal and clutch wear
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.
Loss of even or odd gears with transmission warning messages, Hydraulic fluid weeping from the gearbox weep hole, Clutch wear running ahead of expected mileage
- Test gear selection in reverse and low-speed manoeuvres when cold and warm
- Inspect the gearbox weep hole for oil residue
- Ask whether the gearbox has had sensor, seal or clutch work done
