A customer review complaining about being charged $300 to tighten a gas cap.

The video opens with a customer review about a mechanic overcharging for a gas cap. It then transitions to a woman in a car expressing disbelief, followed by a mechanic explaining why mechanics need to upcharge. Another mechanic explains that they don't make money on oil changes or tire rotations. The ad then introduces a gadget called FIXD, showing it being plugged into a car's socket and connecting to a phone. The app displays scan reports with estimated costs and success rates for fixes. The video shows the gadget being held by a mechanic, who explains it estimates repair costs. The app is shown again, detailing maintenance timelines for tires, battery, and wipers. Finally, the app shows a function to clear the check engine light, and the woman encourages viewers to get FIXD.
