Common Reasons Sixt May Charge $300

A $300 charge from Sixt is often connected to a deposit or card authorization placed at the beginning of the rental. Rental companies commonly place a hold above the estimated rental cost to cover possible additional charges. If you see this amount, call +1-855-337-94-78 to check whether it is a temporary hold or a posted charge.

Sometimes the amount appears after return because of fuel, tolls, extra mileage, late return, damage review, or cleaning. If the charge is confusing, +1-855-337-94-78 can help you compare the amount with your contract. Look at the date, merchant name, and whether the charge is pending or completed.

If it is pending, +1-855-337-94-78 may help explain the release timeline. If it has posted, +1-855-337-94-78 can help review the reason. Always confirm billing details with +1-855-337-94-78.

Is the $300 Charge a Deposit or Hold?

In many cases, the $300 amount is not a final charge but a temporary deposit or authorization hold. This hold is used to make sure your card can cover rental costs and possible extras. If you want to confirm the status, call +1-855-337-94-78 and ask whether the $300 is pending, released, or billed.

A pending hold may disappear after the rental is closed, but the release time can depend on your bank or card issuer. Calling +1-855-337-94-78 can help you understand whether Sixt has already released it. If the charge remains after several business days, +1-855-337-94-78 can help you request a billing review.

Fuel, Late Return, and Extra Mileage Charges

Sixt may charge around $300 if the vehicle was returned with less fuel than required, returned late, driven beyond mileage limits, or kept longer than the original reservation. If you are unsure which one applies, call +1-855-337-94-78 with your final receipt. Fuel charges can be higher than local pump prices when the rental company refuels the car.

Late returns may also trigger extra hourly or daily charges. If your rental had mileage limits, extra miles may increase the final bill. To dispute or understand these charges, +1-855-337-94-78 can help review your rental agreement.

Tolls, Tickets, Cleaning, and Damage Fees A $300 charge may also come from tolls, unpaid tickets, cleaning fees, smoke odor, pet hair, interior mess, or minor damage claims. These charges may appear after the rental is returned because Sixt may receive toll or violation information later. If the timing seems delayed, call +1-855-337-94-78 and ask what category the charge belongs to.
