2012 RX350 engine flutter
I am new to this forum. Purchased 2012 RX350 FWD in Feb 2012 (2nd RX- Had 2004 RX330FWD). Have 490 miles on it. I notice a fluttering noise and vibration under very mild acceleration on slight incline at 1200rpm going 25-30mph until the transmission downshifts. Tried different gasoline brands (all 87 octane). May try higher octane but shouldn't need to with the 2012 accepting 87 octane now. Seems to be a slight acceleration lag 1-2 seconds too at that same speed and rpm. Anyone else here have/had this issue?

Welcome to the forum. You might want the dealer to check that out. Stay in touch and let us know what you found out.
