High-voltage battery and charging
Charging faults, range loss and HV warnings. We diagnose the HV system with the factory tool and correct high-voltage safety procedures.

Every model has its own weak points. These are the ones we see most often in Dubai conditions — and how we deal with them.
Charging faults, range loss and HV warnings. We diagnose the HV system with the factory tool and correct high-voltage safety procedures.
Faults in the front e-axle or hybrid control unit that leave the car in reduced-power mode. Software first, hardware only when confirmed.
The SF90 has several cooling circuits. We inspect all of them — leaks, pumps, fans — because a hot battery limits performance.
Correct fluid, correct procedure, adaptations.
A weak 12 V battery causes chaos on a hybrid. We test it first, every time.
Brake-by-wire calibration and proper disc measurement.
At Hallmark Auto Services we work on the Ferrari SF90 Stradale / Spider every week. We know its service schedule, its parts references and the faults it develops in Dubai’s heat, and we diagnose before we quote. Independent, transparent and specialised — dealer-level tools without dealer pricing.
Every job starts with a written estimate, uses genuine parts, is photographed as we go, and is covered by a six-month warranty.
Tell us what the car is doing — or just that it is due — and we will come back to you within working hours with a plan and an estimate.
Collection and delivery within Dubai is available on request.
WhatsApp is fastest. Or leave your number and we will call you back.
The Ferrari SF90 Stradale and SF90 Spider are plug-in hybrids with a twin-turbo V8, three electric motors and a lithium-ion high-voltage battery. Servicing one properly means factory diagnostics, high-voltage training and safety equipment, and the patience to diagnose software before replacing hardware. Hallmark Auto Services is set up for exactly that.
Annual or 10,000 km. An SF90 service at Hallmark covers engine oil and filter, a full inspection of every cooling circuit, HV system and 12 V battery check, software and module check, brake-by-wire and tyre report, and a road test in both hybrid and eDrive modes.
Written estimates before any work, genuine parts, correct high-voltage procedures and a six-month warranty. If you need an SF90 specialist in Dubai, message us on WhatsApp.
Yes. Our technicians are trained for high-voltage work and we follow Ferrari's de-energising and lock-out procedures before touching any orange-cable component.
Commonly a hybrid-system fault stored in the control unit, often triggered by a weak 12 V battery or a charging interruption. We read the modules, clear the root cause and road-test in all modes.
Ferrari's schedule is annual or every 10,000 km, whichever comes first. In Dubai heat we recommend not stretching it: oil, coolant and brake fluid age faster at 45°C, and a SF90 Stradale that sits in traffic on SZR works harder than the schedule assumes.
Yes. Wear items, filters and fluids are genuine Ferrari or the OEM supplier's part; we tell you which and show you the invoice.
Servicing to the factory schedule with genuine parts and a full record does not void a manufacturer warranty, and a complete history from a known specialist is what buyers and pre-purchase inspectors look for.
A standard annual service is usually same-day. Diagnostics take a few hours; larger repairs get a written estimate and timeline before any work starts.
