Regenerative Braking Disabled...MS 2017 won't go into gears

[c2121]

Hi! First post...I just got a new MS 75 2017 last week (it was a showroom car), and absolutely love the car.

Unfortunately, during a drive this morning, I stopped to get coffee, and after I came back 15 min later, the car showed a "Regenerative Braking Disabled" notification. I live in NC and I was driving for >45 min, so it's not the weather.

The car would not allow me to put it into any gear. It was just show "Car Off". See the pic below.

Restarted the console. No luck. Called Roadside Assist, tried to enter/exit car multiple times. No luck.

Called SC, and had it towed to SC. Tow mode worked, thankfully. After having it today, SC has not been able to diagnose it.

I couldn't find a similar issue on the forums...any ideas or experience with this problem?


Thanks for all who post, this community gave me confidence in buying the car, since I was able to learn a ton by reading.

Thanks,
Cris

Interesting. I’ve never heard of or seen this before either. I wonder if there’s a blown fuse or something like that? For some reason the motors can’t send power to the battery pack. Weird

Looks like you may have disable traction control. Look at icon on top of screen. I think regen turns off with traction.

It turns off but the car will still drive. You can disconnect the ABS cable, E-brake and the car will still drive with the traction control light.

My friend had the very same problem. Car towed to SC out of opening hours and the next day it worked normally. SC unable to replicate the problem. Ghost in the shell.

Weird....mine is still in the SC and they still haven’t figured it out after 2 days. Was it recent?

By the way, for a brand new car, how does the ‘lemon law’ work? Do I have a case if the car is in the shop longer than I’ve driven it? I hate it, but it’s hard to trust it....especially if they have no idea...

Every state has its' own version of the Lemon Law. Usually, there has to be multiple unsuccessful attempts to fix a safety related problem and/or a specified time out of service. You can look on your My Tesla web page under documents to download the Lemon Law info.

It was a month ago. Car drives fine since then, nothing done in this matter by the SC.

Well....it looks like their waiting on engineering. They attempted a software update...but they still don't know what's wrong with it...craziness.

At this point it will be at SC longer than I've been able to drive it.

So....I was on 2018.20. Now I'm at 2018.20.5.

That was all it was.....weird, but I'm glad it came back quicker than I thought

Additionally, they said the ECU firmwares weren't all matching, which caused the problem in the first place. With 20.5, that problem is supposedly fixed.
