A woman says a tiny leak in one tire on her nearly new Kia K4 somehow turned into a $300 estimate.

Jenna (@jenna_ration_x) already had a dealership appointment to fix an issue with the car’s weather stripping when one of her tires began losing pressure.

She filled it with air and kept driving, but the pressure dropped again on the way to the dealership. So she asked the service department to take a look.

When the car was initially ready, Jenna says the dealership told her it had added air and the tire was “good to go.” Staff also said they could not find a hole.

Jenna, however, was unconvinced and asked them to check again.
