Pleease

Close, but doesn't have the "rear height control air suspension" (pic below from owner's manual), which I think is included with the "Luxury" trim level.

The large diameter, long screw on the scissors jack corroded while stored in the trunk over the years to the extent that the screw wouldn't rotate.

I assume you had your jack in the correct location.  The GX's designers could have made it easier.  Not many vehicles require crawling under them to place the jack.  

Got ya - thanks.

The GX' jack point location isn't hard to reach from the side of the vehicle.  The other motorist rolled his jack under because of the type of jack he had.

Thanks for your reply & suggestions.

No air suspension (not the top trim level), standard wheels & tires and pavement was as solid as could be; perfect conditions actually.  It was so weird, like mildly Twilight Zone-ish.

The guy who stopped & helped (so great!) seemed to be a real "car guy" - maybe a mechanic - and he was baffled too.  He had a hydraulic garage-type jack that rolls under the vehicle.

Think I'll ask the dealer to check it out/compare it to another GX jack's extended height.  If it's defective they should replace it under the CPO warranty.

In what way did your LS jack fail - not work at all or something else?

A few months back had a right-rear blowout on my 2016 GX460 at expressway speed.  Got it to the right side of the road safely, parked on flat pavement, removed the jack from the rear door compartment and lowered the spare in textbook fashion - no problem.

Affixed the jack to the appropriate point, jacked the right rear to the maximum extent of the jack......aaand the tire never lost contact with the payment.  No way to take it off, and if I could've somehow forced it would never have gotten the spare on - not enough room.  It seemed that the suspension travel let the wheel drop all the way to the pavement despite the jack being maxed out.

Looked around for a random block of wood (etc.) to add some height, but nada.  Fortunately a fellow motorist rolled up with a jack that lifted higher, and I was out of there quickly.

Has anyone else experienced this?  Meant to ask the dealer about it, but slipped my mind at the next opportunity.
