Default Hard start in the am. dealer can't recreate. Help...>>

I have had this problem for a couple of years. On certain mornings, intermittently, the car struggles to start. It cranks, but just barely starts, and sometimes takes a second try. Dealer changed the fuel pump, but it didn't help. Anyone ever have this? Thanks.

Default Are you waiting for the "OK" in the center display before starting?

The fuel pump sometimes needs a few seconds to pressurize the fuel line. Turn the key to on, wait a second or two, then start.

Changing your fuel filter might be a good idea if you haven't in a while...can't hurt.

Default hmmm...never thought of that. I'll try it, thanks. Actually, it gets worse...

when I'm low on fuel and parked on a slight incline.

Default more than likely it sounds like this is your issue...>>>

fwiw...change your fuel filter every 40k regardless....just insures you have clean lines and the motor is getting everything you need.

Default If it doesn't sense the right temperature....>>

Default I see. Warranty ends in 500 miles. Hopefully dealer will consider this...>>

They haven't figured it out yet, and with my luck, once the warranty is over it gets worse and I have to pay big bucks to fix it.
