Hard starting. Usually 2 to 4 tries before it starts
Hard start periodically mostly when warm shut off and driven quickly again sometimes but rarely cold mostly starts second try but always 3rd try. Very strange
it was taking time to star but it was for two weeks and i remember that i took to the dealer to change some of thr recalls and notice the diferent from that day something was wrong..
