2018 Infiniti Q50 — driver seat clicks during left-right transitions

ColdStartLearner641Community StarterMay 29, 20262018 Infiniti Q50 Red SportOrange County

2018 Infiniti Q50 Red Sport, about 94,500 miles. I can feel a small click through the seat base in corners. Mounting bolts appear tight and power functions work. How do you isolate rail play versus the frame or motor mechanism? I am in Orange County. What would you check next?

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 2018 Infiniti Q50 catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. On “driver seat clicks during left-right transitions,” that was the fork that mattered for me. Stop there until you know. If your situation is the opposite, ignore me. This is the version I'd tell a friend.

It did driver seat clicks during left-right transitions twice this week, both times after sitting. No change in mileage feel. I'll poke at it this weekend.

Same neighborhood, different next step: A pressure test beats staring at a dry driveway if the 2018 Infiniti Q50 is losing coolant with no puddle. Save the big job until that test fails. Was this after sitting overnight? Not driving it hard until I know more.
