picked my X from the service center yesterday. i was having two issues:
1) the rear of the X was lower than the front
2) the shudder was felt under hard acceleration or WOT
to fix #1, they replaced:
they found left rear air strut was leaking, replaced both rear air struts, found left ride height sensor was bent, replaced sensor and calibrated ride height
air suspension height sensor ASY RR LH
air spring module rear LH
air spring module rear RH
to fix #2, they replaced:
replaced LH front drive unit clevis mount and both front halfshafts (model X)
all of the above was covered under warranty (with no cost) and i was given an enterprise rental car while the car was in service. service took about 4 full business days as they needed to order the above parts.
outside of getting limited info while the X was in service via the app, i have to say the job is done well and i was not surprised with any costs. wish they kept the X well charged, but by no means was it picked up in a dire status in terms of juice.
let's see how long the shudder will stay away. my 2018 X only has 18K miles on it and i'm sure the shudder was present well before i discovered it by romping on the "gas".
