2020 Acura RDX — clunk when changing from reverse to drive

ColdStartLearner641Community StarterJun 18, 20262020 Acura RDX SH-AWDPhoenix
2020 Acura RDX SH-AWD, about 63,000 miles. There is a single clunk when changing direction at low speed, especially reverse to drive. No vibration while cruising. What would you inspect first: mounts, driveshaft play, differential mounts or CV joints?

Don't overfit one forum story to your car. If it still isn't clear on the 2020 Acura RDX, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. No need to make it theatrical. I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 2020 Acura RDX in Phoenix, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “clunk when changing from reverse to drive,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. If your situation is the opposite, ignore me. Wrote this up on my lunch break.

I'd push back a little: If it still isn't clear on the 2020 Acura RDX, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. If it doesn't change the out-the-door or the repair estimate, it's noise. I'm keeping receipts and dates in one folder.

On “clunk when changing from reverse to drive,” that was the fork that mattered for me. Had a similar mess a couple years ago and that's what finally sorted it. Wrote this up on my lunch break.

Useful. I'll report back after I verify that on my 2020 Acura RDX. I'll update if anything new shows up.

Write down what you already tried. A second data point from another 2020 Acura RDX owner helps more than a generic diagnosis. That's where I'd start. Had a similar mess a couple years ago and that's what finally sorted it. Might be overthinking it, but I'd rather overthink than overspend.

On “clunk when changing from reverse to drive,” that was the fork that mattered for me. This is from a 2020 Acura RDX in Phoenix with 63,000 miles.

I'd keep this practical. Verify the cheap/easy branch on the 2020 Acura RDX before a big repair or a big spend. Then you'll know the next fork. Post the numbers (or the code) and people can get more specific. Your commute and mine probably aren't the same, but the test still applies. This is me being the wet blanket on purpose.
