Requesting an extension before a rental car is overdue
If you need more time, contact the supplier before the agreed return. Keeping the car longer without approval is different from an authorised extension.
Ask how the change affects Calculate whether a mileage allowance fits your trip. For an electric rental, confirm whether Understanding the battery level required at rental return changes as well.
Request a specific new return time
Provide the rental reference, vehicle and proposed local return time. Ask about availability, rate, additional authorisation and the effect on protection or equipment charges. If the return branch changes too, make that a separate explicit request.
Keep the amended agreement
Obtain confirmation that the extension has been accepted and note the new end time. A message asking for permission is not proof it was granted. If the extension is refused, arrange an approved return and another transport plan rather than assuming a grace period applies.
Make an extension request before the deadline
State the current agreed return and the proposed new one, both in local time. Ask about availability, total price, additional security and applicable protection duration. Keep an accepted revision. An unanswered message or a quoted extension price alone should not be treated as permission to retain the vehicle.
