User Reviews

Most reviews are negative about the IQ Car Wash app due to frequent malfunctions, login/account setup problems, and unreliable payments (declines, unexpected charges, preauthorizations). Users report updates breaking functionality and a poor user interface. A minority notes the car wash itself is good and the rewards program exists, but the app's instability overshadows these positives. Overall, the top recurring issues are account access, payment processing, and post-update reliability.

Pros

Car wash service using the app is good when it works.
Rewards/credits toward a free car wash.
Some users report smooth transactions when the app functions.

Cons

App frequently malfunctions or does not work; users report errors when trying to purchase washes.
Account setup and login issues; users cannot create accounts or verify login.
Payment issues including declined cards, re-entry problems, and unexpected charges.
Preauthorization charges (for example, $15) and duplicate charges without clear notice.
Update-related usability problems and a perceived outdated or poor user interface.

The barcode never scans and I finally figured out how to key in the code so I could use the car washes I had purchased.

I just deleted this app for the 10th time. The other 9 times, I reinstalled it hoping it would work. I really like the car wash that uses the app but I get reward credits toward a free car wash, the app returns an error every time I try to purchase a wash. There are other self service car washes in town that I can use, so that’s where I will go from now on. The IQ franchise is either a scam or they have the worst IT department I have ever dealt with.
