No charge ... Just put air in the tires and that's it I was in and out in maybe 30 mins ... Quicker than I thought light has not shown up.... It's been 2 months now
I drive a Corolla S 2015 ...I have about 10k miles ... I drive pretty fast and I get about 31-33 mph .... Something is wrong or just reset the settings of your mph or update it as it says maybe it'll read differently
