Yes, you can extend a Hertz rental. The process is straightforward, but it's crucial to request the extension before your original rental period expires to avoid penalties. Contact Hertz directly through their app, website, or customer service line to check vehicle availability and get a new rate. The extension is not automatic and is subject to approval and potentially different pricing.
The easiest way is through the Hertz mobile app. Log in, go to 'My Trips,' select your current rental, and look for the 'Extend Rental' option. This method provides an instant quote and confirmation. Alternatively, you can call the location where you picked up the car. Be prepared with your rental agreement number.
It's important to understand that the rate for your extension may differ from your original rate. It will be based on current daily pricing and any applicable promotions. Hertz will perform a new rate calculation and authorize your payment method for the additional amount.
If you fail to notify Hertz and return the car late, you may be charged a late return fee on top of the higher daily rate. In severe cases, it could be reported as an unauthorized extension. Always get confirmation of your new return time to avoid any issues.
| Extension Method | Best For | Key Consideration |
|---|---|---|
| Hertz Mobile App | Speed and convenience; instant confirmation. | Requires a stable internet connection. |
| Phone Call | Complex situations or if you have questions. | May involve hold times; always get a confirmation number. |
| In-Person | If you are near the rental location. | Not always the most efficient method. |

Just did this last week. Used the Hertz app while waiting for my flight. Tapped "extend rental," got a new total in seconds, and confirmed it. Super easy. The price was a bit higher than my original weekly rate, but still cheaper than booking a new one-day rental. The key is doing it before you're officially late. Don't just show up a day later; that's when you get hit with fees.

Failing to properly extend a Hertz rental can lead to significant complications. If the car is not returned on time and no extension is requested, Hertz may classify it as a "failure to return" incident. This can trigger additional fees, and the car could even be reported as stolen to the authorities, causing serious legal trouble. Always communicate with Hertz proactively to ensure a smooth extension and protect your record.

Compared to other major companies, Hertz's extension policy is quite standard. The ability to handle it via the app is a major advantage over competitors that require a phone call. The main variable is cost; extending a compact car on a quiet Tuesday will be cheaper than extending a premium SUV over a holiday weekend. Hertz's pricing is dynamic, so the extension rate reflects real-time demand. Their policy is generally customer-friendly as long as you follow the procedure.
