"Car needs service power reduced" warning

Saw this warning "Car needs service, power reduced" in the car when I got in the car this morning, having to be somewhere else in a hurry, I asked my husband to call Tesla and left in another car (ICE, yikes) my husband powered off the car and back, and the warning disappeared. We took the car out later and no problem. He did call Tesla, and the dispatcher said that she had heard of it before, but since the warning went away, there is nothing to do. It was a little worrisome to see the warning, not wanting to be stranded somewhere. Just thought I would let you know so if others see this, try power off (on screen) and on and see if it goes away before panicking.

Skim down these threads. It's probably attempting to download the new software version.

This is a known issue with the car software. It's fixed in the latest version, which is making it's way to all the cars right now.

I had this once in the first couple of weeks driving my car. Drove from our house in Baltimore about 45 miles to Rockville, mostly highway, mostly with CC set at 64. No rabbiting etc. After showing the car off in the driveway for 15 minutes or so, piled some folks in for a test ride and got a message saying Service Required, power reduced. It may have started off like that as soon as I put it in gear, but I was showing off, answering questions, etc., and didn't notice for a few dozen yards. Car drove like a golf cart for the two blocks it took me to turn around and return. Parked, powered off from the menu, and powered back on after a few seconds. Everything was fine after that.

Response from Tesla about this issue was:
The situation with the powertrain loss of power is a software related issue and is known. Basically, if the car is driven for an extended length of time and then sits in park with the driver in it, then it will go into limp mode. The software team is working on a fix for this and will be most likely addressed in the next package update. The suspension is the same situation and will be addressed in the next firmware update.

Oh, the reference to suspension was in response to this:
Sitting parked in the garage, we raised the suspension to it's highest, then got an error message when we tried to lower it again. The error was persistent for the three or four attempts we made at that point, but didn't come back later when I drove away. I raised and lowered it successfully later with no issues.

So you could end up limping on tip-toes ....

;) LOL

talked to Tesla, it's a software bug from the current minor release, and will be fixed.
they also said that minor software updates are done automatically and do not require owner to schedule the update. I did not know that before. I did have one that I had scheduled, and thought they are all like that, but not true.

Got the "Car needs service, power reduced" message yesterday. Went away after 15 min. Tesla is investigating. Anyone got it recently? I'm on 4.4

I was driving on a 50 mph Rd. Stopped at a traffic light then warning came on. Acceleration reduced by 95%. 0 to 25 mph took 25 seconds. Very dangerous to drive when power is reduced. Called Tesla, will get a call Monday from service

@Portia

Those are called "silent updates".

@patp

Read responses above.

@ Captain_Zap

Read dates on messages.

Better late than never
