smartlift lowering the car when parked

[RSouthern]

Looking to see if anyone can help me understand what random variable I'm overlooking. I park in covered multistory concrete lot at work (away from the sides of the lot) and in a covered garage at home. I have to raise the Taycan to a raised height in both places to clear the speed bumps (garage) and the parking rack foot (home). Basically I can't get to these locations without scraping something if the Taycan is in normal or lower ride hights, so I have smart lift set to remember these GPS locations and it almost always works correctly, and for those times when it doesn't, I press the raise button manually and get on with it.

So here's what's weird. twice in the last few weeks, the car has lowered itself when it was parked and I was away. I didn't catch it either time and have rubbed the underside of the front spoiler or the rubber wind deflectors by the wheels, so it's a potential problem, especially reading the other threads about the battery compartment damage costing so much and potentially voiding a warranty.

Normally the car will stay in the raised position. it's 99.99% time reliable, until it suddenly isn't.

Has anyone else had this problem and any idea what might be causing it? I was wondering if maybe the GPS signal was weak/unreliable given that the car was in a covered area and maybe it got some inaccurate signals and decided it was in motion and lowered? I'm kind of grasping here since I can't think of any other reasons. If the car was straddling a speed bump, that could cause damage to the undertray.. so conceivably damage caused by being parked? That would be a fun warranty fight.

anyone else have ideas?

Odd indeed. Doubt GPS is to blame when car is powered off unless the lowering occurs on power on and no signal.

Two things affect our 2020 Taycan Turbo S:

1. I forget and change the drive selection to INDIVIDUAL (SPORT with LOW is my normal use) and it immediately lowers. I think any change in drive selection might lower the car.
2. Software updates appear to affect the drive height. Default in our Taycan is now LOW in every mode except NORMAL, which is REGULAR (speed sensitive to LOW).

I have been bit by concrete stops at chargers where I had to raise the car to get close enough to charge, then promptly forgot and selected INDIVIDUAL to leave. Keeps my detailer employed!

I leave the car in normal all the time for commute drives (and most driving if I'm honest). I had thought that maybe defaulting to a different mode was causing it, but I'm 100% certain I drove in normal, parked in normal and didn't change modes accidentally when leaving or returning. The knob was not touched and the mode was left in the default setting.

Are you parking on level ground or on a slope? I noticed my car (in normal) dropped the rear suspension and levelled the car up (to some degree) when i locked it on my driveway, which has a slight incline. It didn't just settle and it was very much an immediate and pronounced movement from the car, so something in the car decided to do it! I haven't really noticed it do it before, certainly not to that degree. Maybe some OTE improvement?

Not that it solves the issue, but it may be that?

I sometimes sit in the car, waiting/working on the laptop, with ignition off for 30 - 45 minutes (between appointments)
Every now and then (like once every 2 months or so) it does some random weird thing, for example yesterday it showed it was logging into my porsche-ID, twice in 15 minutes. Never seen that before. Maybe some automatic update or something?

Also seen it lower the driverside window a tiny bit and then instantly back up again. Once i was sitting in the car in a parkinglot, after like 30 minutes it suddently decided to fully deflate the back support of my seat while I was in it LOL

So I wouldnt be surprised it usually remembers its ride-height just fine, until once it doesnt.

Unless you have explicitly lifted the car and left it in that position then on power on / off the car always returns to the default setting (Normal).

I have knocked off the rear passenger jack point twice on high curbs.
Now I am very vigilant about speed bumps, etc., and regularly use GPS enabled Easy Lift.
It's too bad Porsche can't elevate the jack points so they are less exposed.
The side skirts are not expensive, but a bit of a pain to replace.

Both locations are level ground, so I don't think the car is trying to level itself. My garage floor is very level and I'm parking on the level sections of the garage so "pretty level", not on a ramp section.

The car does have dynamic chassis control (DPCC), but I thought that would only be active when in motion and when there are G-forces moving the car in different directions. Not sure if that could be a factor here, but again. The car is parked, turned off, on level ground and out of clear line of sight of the sky. I have noticed PDCC will adjust the car at a traffic light, doing some small up and down adjustments in the front and rear to level it (caused by ripples in the street from tires/acceleration?), but this is nothing like that. The car was in a raised position when parked (blue button/light lit on the dashboard) but later, when I realized it was contacting the speed bump or lift foot, the car was no longer raised. I now double check every time to avoid problems. But it shouldn't do that... not by itself. And most of the time it doesn't do that, it stays at the setting I left it on. It seems like there's some condition being accidentally triggered and I haven't figured that out. Maybe some software update or PCM reset? I wish there was a way to tell if one of the computers/sub-systems had restarted.

I can't speak to the larger issue here, but I suspect that's not solely PDCC, because I have observed that same little "shimmy" phenomenon at traffic lights, and my car doesn't have PDCC.

Glad it's not just me then, guess they all do the shimmy at the lights. I thought it was strange since our X7 and my now sold Mercedes S550 are on air shocks and I've never noticed it with them. Maybe it's a Porsche thing?
