A significant number of users, approximately 30%, report persistent login issues with the app, where they are immediately logged out with a 'session expired' message, making the app unusable for them. This issue is particularly prevalent among users with Google Pixel devices running Android 16.

Every time I try to login, it tells me my session has expired, and to try to login again, so I can never get to my account.

Around 20% of users express frustration with long wait times at rental locations, even for Fastbreak members, which negates the convenience promised by the app and service. This issue often leads to users switching to competitors.

Despite being a 'Fastbreak' member, I still had to wait in a 4-hour queue, so I walked over to Hertz instead.

Approximately 15% of users face difficulties in managing their reservations through the app, such as modifying or viewing current bookings, which often results in errors or requires them to start over.

I was unable to change my reservation and get a car earlier.

About 10% of users complain about unexpected fees and charges that are not clearly disclosed during the booking process, leading to dissatisfaction and a sense of being misled.

I was charged $50 for a cancellation fee that I wasn't informed about, and it feels like a joke.
