I have a 2016 limited outback delivered 2/2016. Loved it the first year- everything seemed great. Starting in late winter, at any stop, the car would tremor as if it was going to stall even though RPM's never wavered. Fast forward to warm weather and I noticed that anytime I accelerated, the A/C blows warm air until I finish the acceleration. I took it in for the 24k service and was told they installed some update to fix the tremoring at idle and that the A/C issue was just how it is because of fuel efficiency -A/C system is ok per the dealer. Still having the same issues and just put 2 and 2 together and realized that the tremoring at idle stops when the A/C is turned off. Is this normal?!? Thanks for any advice!
