2024 Kia EV9 — rear end still feels floaty after new shocks

ColdStartDIYer320Community StarterJan 5, 20262024 Kia EV9 GT-LineDetroit
Shocks were replaced and there are no obvious loose parts, but the rear still feels vague over highway undulations. What alignment, bushing, tire or installation issues could mimic worn dampers? I would rather test this logically than replace parts.

Write down what you already tried. A second data point from another 2024 Kia EV9 owner helps more than a generic diagnosis. That's where I'd start. If it doesn't change the out-the-door or the repair estimate, it's noise. If this is nothing, great. I want that in data.

Don't overfit one forum story to your car. If it still isn't clear on the 2024 Kia EV9, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. This is from a 2024 Kia EV9 in Detroit. Take it or leave it — that's what I'd do. A day of patience here is cheaper than a wrong part. I'm keeping receipts and dates in one folder.

Owner notes beat generic advice here. On the 2024 Kia EV9 in Detroit, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “rear end still feels floaty after new,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' That's my plan before I call anyone.

Following up on rear end still feels floaty after new: still happening, but I have better notes now. This is me being the wet blanket on purpose.

I'd keep this practical. Verify the cheap/easy branch on the 2024 Kia EV9 before a big repair or a big spend. That's where I'd start. 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. I'll update if anything new shows up.
