So i own a 2016 rx350 with less than 15k miles on it. All repairs and maintenance was done at Lexus. I try to start my car today and it rattled and my car vibrated and didnt start. So i turned it off and did it again, this time it started. I got to work and after work the same issue. I basically need to restart the car like 2-3x before it actually starts up. Anyone know what could be the issue?

 

AutoZone can tell you if it's the starter,alternate,or battery if you wanted it checked for free

 

Your car is still under warranty. I would assume you'll be taking it to the dealer.

 

On my 2016 Rx 350 it demonstrated the same problem. Dealer replaced the "Brake Servo" and that fixed it.
