OTA Update 2.6.16

So I’ve been receiving (stability control and regen braking unavailable) warnings for very short periods of time, especially when driving over potholes or uneven surfaces, then another alert saying (stability control and regen braking restored). Anyone else experiencing this?

Yes. I don't think this is new behavior, just a more active warning. To let ABS do its job, regen is temporarily disabled when the car detects a bit of wheel spin / loss of traction.

I did . I have an appointment this coming Wednesday to drop off the car . I mentioned to them the high probability this issue is software related but I got the standard answer: will report to the team

Let us know how it goes. It would be nice if we could get an OTA Patch to fix what I assume is a bug with 2.6.16. If not, I will have to make an appointment as well.

Right, it just feels more frequent/sensitive than before the 2.6.16 update

Correct. This came up a few times so they decided to actually throw warnings about it. Basically, regen is the enemy of traction when there is slip, and the TCS can’t keep up, unless you’re in a 2025+ Pure RWD, Sapphire, or Gravity.

It’s super short though, and only during the slip. But because losing regen can feel jarring, they warn about it now.

Got the update yesterday for my ‘22 GT. I didn’t get a chance to check things out until this morning. Immediately, I got the Drive System Warning error message. I did the hard reboot but still there. I needed to take my wife to the airport in Phoenix so I decided to drive it anyway as it seems was operating normally. I even engaged Dream Drive to check it out. DDP seemed much smoother for the short time I had it on. Lane change seemed very smooth. Decided to call Customer Support before I left the airport. She asked if I did the hard reboot. Yes I did. She then sent a message to the Scottsdale SC and I decided to heard there since I was very close. I actually got to the SC before the Service Request came in. I talked to them about the issue. They have not seen or heard anything yet. They insisted I leave car just make sure I didn’t get stranded. Very accommodating as usual. I have a loaner and they will be in touch with me most likely tomorrow. Stay tuned….

Here’s the update. It appears that the warning had absolutely nothing to do with the software update. Just a pure coincidence. It was a coolant 5 Port Valve that failed. Apparently not common. Luci is back in my garage. Great job all around at the Scottsdale SC!
 
FWIW, I first noticed the “stability control and regen braking restored” maybe a couple updates ago — not sure if anyone else noticed that also.

Not to derail the thread on 2.6.16, but re the following:

— does anyone know if there are plans for those of us who have an Air that is not a Sapphire or 2025+ Pure RWD to receive the updated TCS via an OTA update? Or is there a hardware component that means we won’t get it?
 
I just got this same error on my ‘22 GT after upgrading as well. Guess I’ll try the reset and see what happens. FWIW, it didn’t show up until I charged the car after the update.

It is hardware and cannot be updated by software.

I thought 2024+ Pure RWDs have the sapphire TCS that was developed in-house. Is that wrong?
