My park assist wasnt working. Garrett from "G-Tech Mobile" replaced a parking sensor which didn't fix the problem. Had Pavle from Mint Auto come in and he quickly found the wiring to the sensor was broken. He replaced the wiring and put the old sensor back in. Turns out the original sensor was fine, however due to Garrett's lack of due diligence, I am left with a parking sensor from Ford that I never needed and can't return. Mint Auto is the place to go for any vehicle needs.
