Typically when I get a similar error to “Tire Pressure System Needs Service”, I’ve added air to the tires and it’s been resolved, but all my tires were at 45 PSI this time.
Turns out that one of my TPMS sensors is defective. Second time this has happened.
Due to incredible Tesla service of picking up car and returning it washed, this will be a minor inconvenience.
Perhaps it would save Tesla and me future hassle of they replaced all the TPMS sensors.
Something similar happened with the door handle. When it got stuck a second time Tesla replaced the others.
