Car lowers onto parking curb

Noticed my car lowered itself on to curb after parking when backing out. Happened twice now after 8 months of ownership. Scratched plastic bottom a bit. Called service and they told me this will be addressed with next firmware update. Has this happened to others recently? Saw posts about this previously after volkerize search. Be careful out there. Has not happened before to me. Rebooted system with thumb controls in hope that this temporarily resolves issue.

Happened to me yesterday. Hadn't happened to me in a very long time (many, many months)

Never happened to me.

Not in any way to make light of this, but even cars without air suspension have this issue some times. We once hand an Acura Legend that was just high enough to park with the nose over those parking stops. After sitting for a while the suspension would settle and when you backed up it would scrape loudly. At least with the MS (until the update) you can raise it up if you catch it.

Happened to me twice in the last 30 days. I've owned my S for 16 months and had never happened prior. Seems to have started after the last software update. Called service and was told that this was normal, but I didn't buy the response. 15 months without an issue and now it happens twice.

It happened to me a couple times as well.

Now, when I pull into a lot, I raise the car to "Very High". As soon as I hit "park", I also put the car in "Jack Mode".

When you leave, the "Jack Mode" will automatically disengage. Problem solved.

Me too. Once this made the chin grind on the curb. The other time, my mom in law was stepping out of the car for after the first ride and exclaimed "wow, look how sophisticated this car is!". I didn't tell her that the behavior of the car was a bit strange...

Happened to me last week. Now being very careful to park just before any curb or bumper.

Just happened to me last night. I use l Standard mode and parked front nose over a cement parking block with easy clearance. Came back 3 hours later and backed out with a raucous scraping and thunk. Got out of the MS and MS had self lowered itself to Low setting. I raised it up to look underneath and thankfully only bottom scrape of the underbelly plastic facade. What's with the phantom lowering, never did it before ....
I plan to use Jack mode when parking as previously mentioned until v6 fix!

In what circumstances does this happen? It has never happened to me in 18 months and makes no sense why car should lower itself, but certainly would like to avoid an expensive and painful scrape..

Back in :)

Maybe it started this habit with the custom lowering options. Bug?

My 2006 Audi A6 (with the same suspension) did this every time. They never addressed the issue. I was told not to park over curbs. Some A6 owners had serious damage. Audi was eventually sued. I opted out of any air suspensions since. That means 4 cars without air suspension.

In all fairness though, I just like the feel of the metal spring suspension better.

DC@Tesla - good question. Hadn't happened to me in months, then suddenly out of the blue it did. Strange.

It's probably a good idea then to raise the car before backing out. I had this happen in my 2006 Prius with conventional suspension. Not only did it settle onto the concrete curb section at a hotel but that concrete was not affixed to the floor and my car dragged it out. I had to get hotel maintenance to help lift the front of my car while I backed off of the thing.

This is happened to me quite frequently in the past few months as well. Has anyone reported this to their service center?

I'm curious, do folks find the Model S is more likely to scrape over speed bumps? Scraping under front section is mostly innocuous (cosmetic). Scraping the battery pack - while most likely little risk - would be something to best avoid if possible.

I recognize the car self-lowers after being parked - probably due to a software bug related to initialization when you return to a parked vehicle and prepare to drive away OR related to car being put in Reverse and suspension adjusting unintentionally. Just sounds like a bug.

My car has never done that. It always stays at the height were I left it....

Same for me - it's never happened in 16,000 miles (although I have no idea how many times I've parked overhanging a curb).

What I suspect is happening is the auto-leveling is working. People are in the car and park. Everyone gets out of the car and the springs make the car go higher. Auto-leveling lowers the car to be at the same height as when you first parked (still should be fine). Now you come back later and pile in. All that extra weight lowers the car. It likely takes 30 seconds or so for everything to turn on and the auto-leveling to raise the car back to normal height. If you pull out quickly, it hasn't had enough time to auto-level. Leveling is not super quick and never will be.

This is unrelated to the control panel height adjustments and assumes they remain at the same state (i.e. normal).

In a prior thread the consistent issue when this occurs is when the occupants were rather weighty (I'm trying to put this politely). Those that didn't see a problem (like me) are fairly lightweight, and may be why some people never see the problem. From that very informal poll, it seemed to be more likely to occur with 180-200 lbs or more people weight. Those under 180 lbs didn't see this occur.

Tesla might be able to deal with this. The software would have to detect when people get out and leave the leveling as-is. Not sure what other problems concerns this will cause, but there could be a future solution/improvement.

I usually go into very high manually before parking next to a curb and when I return it is still very high. Have never seen it self lower. Wonder if this is making the difference.

It's always happened for me. I've just learned to never stick my nose over anything. If it means my ass is too far out I set it to high before pulling in. I leave the screen up to remind me.

Never scraped the curb yet but yes my car lowers itself at random after parking and just as I am walking away. Usually makes a strange noise as it does so.

This will be something that I will have to be conscious of when my S arrives. Currently, in my old Town Car, I park with as much of the nose over curbs as possible due to the length of the car.

The Town Car has air suspension and load leveling as well and I have on more than one occasion scraped the underside on the curb. The difference between this and scraping the S is that the Town Car only cost me $1500!

Hopefully I won't rack up to many scratches before I change my parking habits :D

This happened to me yesterday. I usually go into "Very High" when pulling into a parking spot and haven't had the car go low on me.

Yesterday, I decided not to use Very High and left it on Normal. I was able to pull into the spot without hitting the curb.

When I came back, the car wouldn't back out of the spot easily - and that's when I realized it had dropped to Low - and that I had chosen not to use Very High when pulling into the spot.

I'm going back to using Very High whenever parking with the car hanging over the curb.

It has only happened to me once, but it was shortly after the software that allowed suspension lowering again. SInce then I rarely park where I hang over anything and if I remember, I raise the car to very high.

I've never had this happen but I would appreciate some clarification. If you leave it at normal as bp did and the car has lowered, has the actual setting changed from Normal to Low or has the car changed its height without a change to the control screen?

@Tap, that guess sounds very plausible to me and matches my experiences.

@loefvinc: "even cars without air suspension have this issue some times. We once hand an Acura Legend that was just high enough to park with the nose over those parking stops. After sitting for a while the suspension would settle and when you backed up it would scrape loudly."

You've seen it happen, but I have a hard time believing standard suspensions would "settle" like that and make the car go lower.

So in addition to not wanting the terrible repair bills when the air bladders start going out in the 10 to 15 year time frame, this thread is another great reason why I am really glad I did not get air suspension. I know you all like it, but that sounds really nerve wracking.

Umm... Is it necessary to park over curbs, or is this just a bad habit? You wouldn't get close to a curb in a sports car, but you might miss the spot entirely with an SUV.
