Rental Car Extension Letter
The insurer set a date to end your rental, but your car isn't fixed and the delay isn't your fault. Fill this in to get a dated, polite letter asking for an extension, with the reason and the number of extra days.
Your letter
Whose insurer is paying changes the rules
If the other driver caused the accident, their insurer owes you loss of use: generally the cost of a comparable rental for the time reasonably needed to repair or replace your car. A cutoff date picked from the shop's first estimate isn't the limit when the delay comes from back-ordered parts or the insurer's own slow approvals. Connecticut's insurance department, for example, says loss of use covers the period reasonably required to repair or replace the vehicle.
On your own policy, rental reimbursement pays up to the daily and total limits you bought, such as $40 a day for 30 days. Once those run out, the extra days are yours to claim from the at-fault driver's insurer, if someone else caused the accident.
Make the request stick
- Send it before the end date, by email, so there is a timestamp.
- Attach the shop's note on the delay: a parts back-order notice or a supplement request date.
- Ask for any refusal in writing, with the date the insurer considers reasonable and why.
- If they cut it off anyway, keep paying receipts or a log of days without a car and claim them as loss of use.

Frequently asked questions
Can the insurance company end my rental before my car is fixed?
On your own policy, yes, once you reach the coverage limits. From the at-fault driver's insurer, they owe loss of use for a reasonable repair or replacement time; if they cut the rental off early, you can still claim the extra days from them, backed by the shop's records of the delay.
How long does the rental last when my car is totaled?
Usually until a few days after the insurer makes a reasonable total loss offer or pays it, not until you find another car. If the offer is unreasonably low or slow, say so in writing and ask for the rental to continue until it is resolved.
What if I'm paying for the extra rental days myself?
Keep every receipt. If another driver caused the accident, add those days to your property damage claim against their insurer as loss of use.
