Firmware 6.2

[matbl]

I'm seeing multiple reports in sweden that for the 70D, the latest 2.5.46 had their rated range (named typical in europe) display at 90% charge increase significantly (20+ km). Anyone else seeing this?

I know very little about the dual motor cars, but if I were to venture a wild-ass guess, it sounded like to me that the two motors were out-of-sync and one was pulling (or pushing) against the other causing the shudder.

Potential downside of Tesla's much-lauded electronic AWD linkage?

I don't, but I'm in the US. Software glitch?

I'm on an early VIN P85D with firmware .36. I'm seeing a weird shudder when the car is stopped or I allow the car to roll backwards at a full stop. The traction control lights kick in and then eventually recover.

Will check out this weekend here with my 70D. For now, the 50% charge has been exactly the same though with 2.5.46 for about a week now. Still 120 miles each time fully charged to 50%. My first 100% was 246, and last one was 240.

On-grid at the moment, and charging both Model S. At some point the P85 dropped back to 60A from 80A with the whole charge speed reduced nonsense for whatever reason (I've never been able to find a reason). I checked a little while later and it had recovered on it's own to 80A. I've never seen it do this before. Usually once it drops it never returns.

I am assuming you are charging from home HPWC, could it be that the HPWC is self regulating with the car current draw if it sees a source voltage drop or the HPWC itself overheating?

This may be a known defect in .21 and .36; corrected in .46. Vibration between 3 and 4 mph while coasting to a stop - affects all dual motor configs with range mode and creep set to off. You are the first person to mention seeing the traction control lights. Check out the following thread for more details and to confirm if you have the same problem http://www.teslamotorsclub.com/showthread.php/51909-Vibration-at-3-4-mph-at-the-end-of-regenerative-braking

Hard to tell. It may be similar. I think I'm seeing the traction control lights go on when I accelerate out of the shudder, say at a rolling stop sign or when the car rolls back. Only started seeing it in .36.

.46 causes LTE failure - you'll see signal bars but no "LTE" or "3G" or "E" indication. No maps, no voice commands, no app access. "A new version is coming next week." Feh!

I've had that with earlier versions. Well, not lte but 3g failure.
reboot the center display and wait a couple of hours...

EDIT: My 100% took me up to only 238 Rated Miles this time. It sat there charging at 1-2 amps at end and I didn't have time to wait an hour or so for it to finally complete. Maybe the upper area is just needing more use as I typically just charge to 50% nightly right now in Summer, and maybe get down to 30-40% lowest during use most days.

And what was your 90%?

And now something OT.
i read a piece about li-ion batteries today. You should actually keep them above 60% to make them last as long as possible.

Interesting, my 90% was 213 this morning, seems to drop fast at times 3-5 miles a day sitting in garage.

This is not correct. Do you have a source? The cells definitely prefer to be stored below 50%. For daily cycling, keeping it right around the midpoint is advised.

Right, the main thing that affects lifetime is total time spent at or near 100% or 0% charge, particularly at high temperature. Details here.

Had a surprise this afternoon when traction control activated on a dry surface while under mild acceleration. The car very sluggish and I thought I had some sort of power failure.

Yeah, I've had this happen to me once. It was while merging into another roard from a T junction. Scared me for a second because it wouldn't accelerate for a second or two and I thought I would stall in the middle of the two way road. 2 seconds later, everything was normal. Phew :/

Yeah, the car sort of shudders / stalls and then recovers. It's weird.

Same thing here!!!!

I got my tires checked on Friday after the traction control lights had come on. Shop said my tires have 10k miles of thread left. Definitely not a tire issue.
