Rental cars, honestly
Hire car won't start in France? Here's the order to do things in — and who pays for what
A dead rental is half a mechanical problem and half a contract problem. Most advice pages skip the second half. We won't: your first call should usually be the renter's own assistance line — and here is exactly when we come in.
Why call the renter first (yes, really)
Your rental agreement almost certainly includes assistance, and using it keeps the cost and the liability on their side of the counter. Calling anyone else first can turn their problem into your expense. We'd rather tell you that plainly and be your second call than pretend otherwise and be your regret.
When we're the right call
- The assistance line doesn't answer (nights, Sundays, August) and you have a ferry, flight or checkout that won't wait.
- They've authorised a local intervention — some renters will, to avoid a swap-car transfer for a ten-minute fix.
- You need the car started once to return it to the depot and hand the problem back.
- You want an independent measurement of why it died — delivered-weak batteries are a real thing, and our written diagnosis states the measured cause.
What you get that matters later
Beyond the restart itself: a time-stamped, itemised invoice and the measured state of the battery, in English. In a dispute over a delivered-weak battery — or a claim on your card's rental cover — that document does the arguing for you. If you drive your own car in France too, the parked-car scenario has its own page; and the DIY procedure, if the renter hands you jump leads, is in the jump-start guide.
Hire-car questions
The rental desk is closed and the assistance line doesn’t answer. Now what?
Document everything (time-stamped photos, call log), then decide how long you can wait. If you choose to call us, keep every receipt and our itemised invoice — renters have successfully recovered costs from the rental company or their card insurance, though we can’t promise your outcome.
Will fixing the battery myself (or via you) void the rental agreement?
Most contracts require you to contact the renter’s assistance first and may treat unauthorised repairs as your cost. That’s why our advice is honest: call their line first. Where they authorise a third party, or leave you genuinely stranded, our itemised invoice is your evidence.
Whose fault is a dead battery in a hire car?
If the car was delivered with a weak battery, that’s a fleet-maintenance issue — note it at handover if the start already sounded laboured. If the lights were left on all night, that’s usage. Contracts differ on both; the invoice and diagnosis report we give you states the measured cause, which matters for that discussion.
Can you just come and get it started so I can return it?
Yes — a boost plus a written note of the battery’s measured state is often exactly what you need to get the car back to the depot and make the paperwork their problem. We won’t replace a battery on a rental without the renter’s authorisation.
Does my travel insurance or credit-card cover help here?
Sometimes — rental-vehicle benefits vary enormously. What every claims team asks for is documentation: our invoice itemises date, location, measurements and work done, in English.
