I started noticing that as well. I too have a 2016 QX80. The engine catches up, bit there is an initial lag. I don't know why though.
I have a 2016 purchase couple months ago and between 1 & 2nd it has a lag and the tach pops up and downHello.
I have a 2016 QX80 and recently it has developed an issue where there is slight hesitation when doing mild/moderate acceleration up to about 50mph or so. This issue has also seemed to have coincide with decreased MPG.
Has anyone else experienced this?
