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.
