Car sometimes fails to start on first try.

My '19 Outback is 8 months old. Over the past 2 weeks I've had this happen 5 or 6 times. Turn key, engine turns, tachometer swings to the top, but does not come back to 2000 on the way down, but stops at zero (engine not running). Car has always started on the second try. When this usually happens, motor is warm (driven a half-hour prior). Never had this happen in 50+ years of driving. Will take it to my dealer, but hope they have experience with this. Comments? Thanks.

Yeah, sounds like you likely have a problem that needs to be addressed by the dealer. What you describe is definitely not common, but there was someone with a similar problem on a 2018 a couple months ago. Unfortunately, they never returned to post an outcome. Presumably it was fixed leaving them with no incentive to come back.

If tach swings to the top, it sounds like an ignition problem. When cranking, the tach should show the speed the engine is cranking.

That is not true. The dials all do a swing during startup.

Agree.... this feature can be toggled off on the 2016. Maybe other models too. I believe the idea is to exercise the gauge's servo motor thru it's entire range

Not necessarily. That is a user-selectable option.

And the dial swing occurs before the engine is cranked. I've never paid attention to the tach when starting, so can't say if it's displaying anything until the engine actually starts.

If the tach does register the RPM while starting, and it probably does, I doubt the starter turns the engine fast enough to move the needle by much.

One place I just looked says typically ~200 RPM, which is faster than I would have guessed. I may have to look, in case I need this information for future reference.

Both my tach and speedometer swing all the way up when first starting. The tach returns to "normal" and the speedometer to 0. I'll need to wait a week to get it to my dealer. Today was a total of 5 good starts, 1 re-start.

if this were a old timey car I would suggest it were something that was not shutting down properly and not resetting. and then on the second turn of the key it is where it belongs.

things on old timey cars, like relays and springs. (each effected by temps of the operating engine / ambient air from a drive, a shut down and a cool down)

but this is a new fangled contraption,...that is only 8 months old, ....so I wish you the best of luck at the dealer of your choice.


? Want people to stop needing to ask what exact car you have? year -model -engine -trans, scroll down to "your car":
