Tesla Semi maintenance cost — service schedule, wear items, and yearly total (2023)

Tesla Semi service schedule and what each visit covers

The Tesla Semi's service book is short on purpose. Most line items are inspections, not parts changes. On the Tesla Semi, the recommended interval is typically annual or at a fixed kilometre count — whichever comes first. The visit covers a multi-point inspection, brake-fluid check, coolant top-up on the high-voltage cooling loop, software updates, and a 12 V battery test. Most owners are in and out in half a day at a cost that lands around the $600 mark for the visit itself. Tesla's service book for the Tesla Semi is generally easy to follow and the workshop network is set up to handle it efficiently.

Wear items on the Tesla Semi

For the Tesla Semi, the wear-item bill is mostly tyres and 12 V battery — both predictable and budget-able. The Tesla Semi weighs in around 27000 kg, which is on the higher side for its body class, so tyres are the meaningful wear-item line on the budget — expect a set every 35,000–50,000 km depending on driving style. Brake pads, by contrast, often last well beyond what they would on an equivalent petrol car because regen on the Tesla Semi handles most of the deceleration. Wipers, cabin filter, and washer fluid are negligible items but worth keeping on a yearly checklist.

Tesla Semi battery cost and warranty

Treat the Tesla Semi's battery well in the first three years and you'll likely never spend a on it. The Tesla Semi ships with a 900 kWh pack and a 8-year battery warranty (often paired with a kilometre cap), which covers most of the realistic ownership horizon. Field data on similar packs shows modest degradation under normal use — typically 5–10% capacity loss in the first four years. That curve is shallower if you keep the daily charge cap at 80% and avoid frequent DC fast-charging sessions.

Tesla Semi five-year ownership maths

Putting the Tesla Semi numbers together: $1,200 of scheduled maintenance, plus tyres amortised at roughly $250 per year for moderate-mileage Tesla Semi owners, plus $4,000 insurance, plus energy at $0.08/km. For a Tesla Semi owner driving 12,000 km a year, that all-in figure typically lands well below the running cost of a similar gasoline equivalent — and the gap widens as fuel prices rise.

Practical next steps

Book ev.care for the Tesla Semi's wear-item visits — tyres, brakes, 12 V, cabin filter. Workshop pricing on these standard items is usually 20–40% below brand-dealer rates.

Frequently asked questions

How much does Tesla Semi maintenance cost per year?

Expect roughly $1,200 per year for scheduled maintenance on the Tesla Semi, plus wear items (tyres, wipers, washer fluid) as needed. The schedule is once-yearly for most owners.

Are spare parts expensive for the Tesla Semi?

Routine wear items (brake pads, wipers, cabin filter, 12 V battery) for the Tesla Semi are priced like any modern car. Powertrain-specific parts cost more, but are rarely needed under normal use.

What's the most expensive thing that can go wrong with the Tesla Semi?

The high-voltage battery — but it is warranty-covered in the period when failure is most likely. Outside warranty, a pack replacement is the worst-case scenario; in field data so far, it remains rare.

What's the per-km running cost of the Tesla Semi?

Energy alone works out to about $0.08/km on the Tesla Semi at typical home tariff. Add scheduled maintenance amortised across yearly mileage and the all-in figure stays low.
