After mounting my spare tire on my 2021 Passport I have warning lights about the Lane Keep Assist, Road Departure Mitigation and Brake warning lights have all come on. I've never seen them before so I assume it has something to do with the spare tire. Curious if any knows if they will go away once I put the regular tire back on or maybe I'll have to reset something.

That's probably because of the tpms sensor that the vehicle can no longer sense from the tire you removed. Everthing should calm down once the original wheel is back on and you have done a little driving with it.

Thanks. Hope that's the case. I'll let you know as soon as I get the tire back.

You don't want to have lane keep while running spare because it can cause weird handling characteristics.
Also spares are only allowed to go no more than 50mph.

yes it will do that on the spare tire. will go back to normal once you put a wheel with a TMPS on.
