Hello ih8mud World,
I am brand new to this forum (previously from expeditionforum.com), and already have burn questions with my 2-day old 2018 LX. I previously owned a 2016 LC, then switched to a 2020 Expedition, and then came back to this LX570.
I went to test drive a few LXs before getting this one and remembered that a different 18'LX had really different AHC performance compared to the one I got. I remember when braking to a stop, it would hold it's nosedive position and slowly level-out, making every complete stop like a chauffeur stop, no matter how bad I was on the brakes. Ours just bounced right up like a normal, passive spring system, similar to our previous Expedition. That one also seemed flatter around corners. The test drive was a long time ago, during the summer on all-seasons, rather than winter tires that is on my car right now, but I don't think that should affect much. I didn't go with that one, because it seemed neglected, parked outside for a LONG time and some wiring by the firewall seemed to had been chewed up, but no codes showing tho. The one that I went with was parked indoors, no rust, interior is our preferred colour, but slightly beaten up (can be cleaned). The biggest problem is that the BSM isn't working, because there is a hole in the right-rear bumper, alledgedly from a parking incident. The dealer promised to fix all of it, which they did, including replacing both of the radar modules. And so, a non-refundable deposit was put down before I did some research and found that the AHC pump is in that same right-rear corner
. That said, we did test the height control during the test drive and it seemed to lower and raise fairly quickly, so Idk if the pump is really affected.
Can some fellow owners confirm that their AHC suspension performs like described above and that I'm not hallucinating, or suffering from buyer's remorse? Also, since the car is 6 years old, according to our beloved Car Care Nut, should I be doing an AHC fluid change at a Lexus dealer and hoping that it would fix "the problem" (if there really is one). Keep in mind, that around my area, there are really, really few LXs, so I'm not sure if my local Lexus dealer is aware, let alone have done such a service before. I believe it's not even stated in the owners manual, so I don't think a lot of people do it. If anyone knows a local AHC expert shop around Vancouver, BC, I would really love to know!
Sorry for all the rambling and thank you in advance for all your help and advise!
