Took delivery of my Model S p100d two weeks ago, was working fine until today. Got into car this afternoon, got rear motor failure alert, followed by air suspension, and 12V battery. have 400 miles on car, charged to 85% at night, was at 80 plus percent charge when this happened. Thankfully the front motor got me home, awaiting road side service. Think I have a lemon...

no, you have a 12v battery failure. something thousands of us have unfortunately had to endure.
you don't have a "lemon". easy on the theatrics.
That's interesting. In the past, we've been told that the front motor is a slave to the rear and a failure of the rear will cause you to lose both (may depend on exactly what the failure is.)

Did you race anyone with just the front motor? If so, you probably still won. In seriousness, how weak was the performance with just the one motor?
Sorry for your situation.
Sorry for your situation.
I changed "bricked" to "failed" in the thread title, because as DillyBop pointed out "bricked" has a very specific meaning.
He's probably right about the 12V.

Tried rebooting car twice with service, no go, guess bad communication with main battery and 12volt. Tow on the way. Damn, hopefully I can trust it after this. Missing my RS7 is just traded
As is well understood by electronics engineers... for any new product, the most likely time to encounter a fault is in the first 24 hours of operation.
Just bad luck. Tesla will fix it up and you'll be back on the road.

Front motor worked fine, got me home with the rear motor failure alert on dash, good thing having 2 separate motors.
I agree...I once had a 12v that died and all sorts of alerts popped up. As soon as it was replaced everything was fine.

I had my traction pack fail in the first 6 months or so, but no other major problems since.
Months later I actually look fondly at the situation, as like with your car it was crippled but still able to drive.
+1 to the nod that the front motor alone worked, just as Elon suggested would be possible. There had been a discussion in the forum here about whether that could actually work or not but your car is now proof (though surely it depends on what fails).
And +1 to Gavine's Q too, what did it feel like ? Front wheel drive Tesla

Great to have 2 motors. That's right. Just like having a twin or 4-engine jet. It will always get you home. Cool! About your situation, it's disappointing I'm sure. But as I always tell myself, it's best for all the bugs to appear now and get the fixes over with. You will be fine.
Yeah, being able to use just the front motor with a failed rear motor is, well, impossible. The rear motor inverter controls the front motor via CAN. If the rear motor fails, there's nothing to control the front motor since the rear motor directly accepts the throttle inputs and all.
I know of no failure condition that would allow this to happen. Front motor failure, sure, but not rear. Also, the only alerts I see related to motor failures are the dev mode related front/rear/both selection and for front motor failure.
So... photos please. If something's changed with this for the P100D, that'd be news to me.

The first error I received was the rear motor failure. Could feel the front pull of the motor, car definitely didn't have normal power, no thrust from rear. Fortunately I was a few miles from my house, and was able to drive it home. Now the car won't start, wrecker is on the way.

Please keep us posted. When my P90DL was brand new I had a cable on the 12V battery come lose (probably due to multiple Ludicrous launches). They fixed it right away and I haven't had a problem with the car since.
Hope it's a simple fix and I'm sure they will make it right whatever they need to do...

A guess is that the condition calls for shutting down the rear motor, for a specific reason that only Tesla knows... ? (well wk057 is working on knowing hehe)
People still having 12 volt battery problems?
Seems Tesla has had plenty of time to fix that. Mine failed at 18months, fortunately giving me a warning rather than a shut down. Why don't they use a Ni Mh battery which last a long time in Prius? Lead acid batteries have a shortish life span on ICE but over 18 months.
