2014 XC-90 Hesitation

[ka5p]

Have 2014 XC-90 w/10k miles. Problem is sporadic (has happened approx 10-15 times over past year).

From standing stop (stop light, etc) -- press on accelerator and VERY LITTLE to no acceleration. Engine continues to run smoothly -- no indication of fuel starvation, no roughness --- just no acceleration. It does NOT appear to be transmission oriented because when it finally "kicks in" there is no feeling of transmission shifting or wild tach movement (to indicate that there was a changing of the gears, etc). I get things back to "normal" by pumping the accelerator (usually a reflex action because the are vehicles behind me wanting to "go"). VERY disconcerting issue. Local Volvo dealer says "cannot find any error messages", etc. My only complaint with the car -- second XC-90 and 5th Volvo.

Can you replicate the problem on demand? Most techs (ok not all of them) rely heavily on the "computer" to tell them what's wrong and (IMO) have lost troubleshooting ability. If you can "show" the tech/service person what happening - then you can get someone working on it.

Good Luck!

Use premium fuel in it. Tip in spark knock can cause it to be non-responsive when it goes into safety knock retard. Did it do it when temps were cold over winter?
