Delivery day - Air Suspension Issue

[XyberTruck1]

Good evening,

I recently had a delivery day and everything looked good, until I tested the air suspension. It was on entry mode and I raised it to high. The cybertruck seem to struggle to do it and took awhile.

I told the advisor and he came out and told me it was normal. He left and I tried it again. I timed it and it took 2:50 to raise suspension from entry to high. I again told the advisor and he got a manager who came out and said it was normal.

I then asked them to try it on the demo truck and reluctantly they did. The demo raised to high in about 15 seconds. They then said I should accept delivery and have it repaired. I did not accept and left for day.

My question to the owners is, how long does it typically take for your suspension to raise from entry to high? I've seen conflicting results and not sure the reason. This truck was a 76xxx vin.

Thank you.

It depends on how full your air tank is/was when you attempted to raise the truck.

My VIN is 760XX. I’ve had my CT since Sunday. The height goes up and down flawlessly. It’s quick.

Takes seconds medium to high under normal conditions.

Just got home, under 10s to get high from entry position

I probably would not have accepted delivery of that one after that demonstration either.
To be clear- they would definitely service the truck and likely fix the issue, but thats no way to start ownership of a brand new very expensive car. Ask for them to rectify the issue before delivery or assign you a different VIN. If they decline then ask to speak to regional sales supervisor.

 

[mbrockus]

it definitely should not take minutes to raise the suspension. Don't blame you for rejecting.

Make sure you test the full range too. Put it into Extract mode via the Off-Road app.

You rejected the delivery, so I suppose it's not your problem anymore, but...

This behavior strongly suggests an air leak, such that the reservoir tank is unable to maintain pressure. Without it, raising the suspension must use the compressor alone, which is much slower.

There's a procedure for leak testing:

https://service.tesla.com/docs/Cybe...UID-C054B5D8-8B78-4B18-B8AD-5C58BF572B94.html


At the very least, they could have filled the tank with nitrogen per the refill procedure:

https://service.tesla.com/docs/Cybe...UID-C054B5D8-8B78-4B18-B8AD-5C58BF572B94.html


but I suppose that not all delivery centers are also service centers. They may have lacked the equipment and expertise, which is why they wanted you to accept and have it fixed (which is bullshit IMHO).

There is a "suspension" category in Service Mode, but the software doesn't seem to be very robust in this regard. You would think that the code could infer a leak by tracking compressor usage vs. height changes, but I don't recall anyone with suspension issues noting any Service Alerts until after a component fully failed.

Suspension service mode does provide pressure readout for several zones, gallery and reservoir being the most relevant.

Right, but it doesn't seem to track usage over time. Even just showing a graph of compressor activity would be diagnostically significant.

It would show a leak or lack of reservoir capacity though.
I just did entry to high in 9 seconds with 5.2 bar drop. 19.7 to 14.5
Dropped to entry in 12s, no change (as expected)
Back to high in 7s, compressor kicked on, ended at 11.5 bar
Highest air spring is 9.1 bar

If it was on rough concrete or asphalt sometimes it gets stuck if you don't wiggle the wheel back and forth a bit.

Same as others. Raising from Entry Level to High is very quick. I did it for the first time a couple of weeks ago using the mobile app (to show a neighbor) and was surprised how fast it got to High height...I'd guess it was around 3-4 seconds. Same for lowering back to Entry Height: very fast.

Not 3 minutes! 10 seconds or so

 

[Tecyber1]

Without checking now (having done it many times), it's quick and damn sure not clocking in around 3 minutes.
