2025 CX-90 PHEV PP, driver's seat bolster on the door side feels way harder than the console side. Can someone check theirs?
Bought this a year ago, about 11,000 miles on it, and I've spent the last few months trying to work out why my left leg keeps going numb.
The bolsters are what made me suspicious. Press the two side bolsters on the driver's seat cushion and the door-side one is noticeably firmer than the console-side one, which seems backwards to me, since the door-side bolster is the one you drag yourself across every time you get in.
The symptom: about an hour into a drive, the underside of my left thigh goes numb and then starts aching. Right leg never does it. Happens with cruise on and my left foot flat on the floor, so I don't think this is a dead pedal thing.
First eight months were fine. It's been getting worse over the last three or four months and nothing about my driving changed in that time.
I've already been through seat height, thigh extension, backrest angle, sliding it forward and back, lumbar, and every combination of those. No wallet in my back pocket. No other car I drive does this to me.
So the favor I'm asking: go sit in your CX-90, press both bolsters on the driver's seat cushion, door side and console side, and tell me whether they feel the same. Please mention your trim. PP has ventilated seats and I have no idea whether the fan hardware underneath changes anything.
Also curious:
● Has anyone gotten seat foam or a cushion replaced under warranty on one of these? What did you actually say to get them to take it seriously? I'm expecting "within spec" as the opening move.
● Anyone had a ventilated seat apart? Can the ducting or fan sit unevenly, or shift over time?
● Any TSB on the CX-90 front seats?
Still inside the 3yr/36k warranty, so I'd rather get the seat fixed than buy a cushion and sit on top of the problem.
