2020 Acura RDX — vibration under acceleration but not while coasting

RotorShopper925Community StarterMay 10, 20262020 Acura RDX SH-AWDPortland

2020 Acura RDX SH-AWD, about 67,000 miles. The car is smooth at the same road speed when I lift off, but under moderate acceleration I can feel a vibration through the floor. What would you inspect first to separate axle/driveline issues from an engine mount? I am in Portland. If I figure it out I will update the thread.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2020 Acura RDX, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. Cold start is when I can actually reproduce it.
