Bummer. I came back to this thread to see how people were doing. I got my replacement a few months ago, right after you did. I was able to charge at 48A again. I kept it that way for a couple weeks then decided I would not risk it and turned down amperage to 36A (from inside the car, and it...

I’m responding to this thread because I see you have at least seen that #3 issue discussed. I think my car has that issue now, unrelated (I guess?) to my prior HPWC issue. First, on topic for this thread and an update to my situation: my replacement Gen 3 HPWC has continued to function at 48A...

I’m getting back to this thread really late—sorry about that. My Gen 3 would overheat at 40A too, dropping the charge to 20A, so the firmware clearly just cuts the rate in half. It could do 36A for hours without problems, though. So I left it at 36A until Tesla sent me a replacement. Note it...

Same part number for me, both my original and the replacement. Unfortunately I still only have a few charges (but at 48A solid) with the replacement gen 3 even though I’ve had it three weeks because my car has been in service for the last two. :-( Should get the car back end of this week. I...

We're all on 0.8.58. For most of us, the problems didn't show up until a month after charging with no issues at all. We assumed it was the firmware, which changed to 0.8.58 around that time, but may it just be something internal wearing out over time? I have a replacement unit but haven't...

FWIW one of the techs told me, as we were talking about this issue, that the Gen 1 and Gen 2 were outsourced, while Gen 3 is a Tesla-designed product, so someone else got the engineering right. Frustrating. I wish I had gotten a Gen 1 or Gen 2 too, instead of the current model. My replacement...

The cord does feel pretty warm. I have had my replacement installed for a few days now and have done several charges up to about 2 hours, and it has always stayed at 48A, no overheating error. But that cord does get pretty warm. My last one worked for about a month before it started giving me...

I just installed my new one this afternoon. One charge under my belt now, only 1.5 hours long but it stayed at 48A the whole time, where the old unit was not able to make it past 45 or 50 minutes without dropping to 24A. Never did the 3 red blinks. Cord did get noticeably warm after an hour or...

I just opened and installed my new one a few hours ago. Did the setup procedure and put it on WiFi but I was hesitant--the firmware was 0.8.55 on it, so it presumably will update to the "bad" firmware. But whatever, I don't want to cripple it because I'm afraid of the firmware. I did a 1.5 hour...

I guess I can't edit this old post again, but I wanted to note my replacement arrived today. I'm not thrilled to be re-installing this myself, but it sounds easy, like even I can't mess it up. Probably will swap it out within a day or two. In the meantime, more updates from those who have...

You've had the opportunity to live with the replacement for a while now, do you have any update on how it's behaving? My replacement arrived today and I'll install it soon but I'm not in a hurry if it doesn't fix anything.

Please do keep us posted with updates once you've had a few charges under your belt. Same firmware, I assume? EDIT - and for what it is worth, I called to confirm I have a replacement coming, it just hasn't gotten here yet. I got my return label about ten days ago.

Where are you located? Sorry if I missed that part.

Holy cow. I will check my cord (also 18') but don't think there's any damage to mine. I definitely had several multi-hour 48A charges until about mid-July, when it started cutting back to 24A. Since I found that 36A works, I've had several multi-hour charges at 36A with no cutting back. But I...

Dammit. So you are getting the 3 blinks and everything just like before except not as often? This is where it would be helpful for Tesla to be able to actually come out to one of our houses to check out exactly what is happening.

Glad to hear this! Looking forward to hearing more. Thanks!

I’m waiting for those with the new wall connectors to let us know if it fixed the issue permanently and the supposed overheating doesn’t return. I got a return label via email but no wall connector in the mail yet. I may call just to confirm my inquiry is still open and a replacement is on the...

I tried 40A tonight, after having multiple 36A multi-hour sessions with no problems. After about an hour at 40A, 3 red blinks and it cut power in half to 20A. Dammit. Last time, holding down the button to broadcast the SSID seemed to reset the unit. So I did that, logged into the HPWC WiFi to...

That's the same part number as mine with the issue.

FWIW I just went out to my Gen 3 charger, which I’ve stepped down (from inside the car) to 36A because I get the overheating error at 48A too. My car has been charging at 36A for over an hour now and the cord isn’t even warm. This whole thing is such a mystery but at least I’m not alone in...

I just read that thread for the first time. I have the long cord, too. It would get warm but not “hot.” But aren’t people seeing this issue with the shorter cord too? I wonder if the new units they are sending us are different in any way (thicker cord?). Also, I saw some voltage drop, too...

I just got a return label in my e-mail too. I saved the e-mail, intending to call to confirm that I don’t have to return the old one before receiving the new. I don’t have my old packing material anymore. I’ll just use the box from the new one to return the old, I guess. But (1) I had an...

Can we even get a Gen 2 connector? If it gave me a reliable 48A, I'd do it.

I totally knew what you meant, didn’t mean to suggest otherwise. The other tech support reps I’ve spoken with were very nice too. The problem is Tesla seems entirely reactive, not proactive. You know, what if Tesla’s Power Device support team had a Twitter account? We could all follow them...

Agreed. FWIW, I spoke with Tesla again today to make sure my case was still being worked, and I got a really good tech POC. It took forever to get through because the same team also supports the Power Wall, and there's a tropical storm that just rolled through the East Coast, so lots of people...

A quick update. I was able to charge via my Gen 3 Wall Connector from 50% to 80% last night at 36A the whole way through, no blinking lights, no throttling. Had I left it at 48A, the wall connector would have switched to 24A after less than an hour, then continued charging at 24A with the red...

WTF are they thinking? There is ZERO chance I am returning my wall connector without having a replacement in my hands first. I'm going to try the 36A limit tonight and see how it does. If that works, at least it will lessen the pain for a while. But I'm also going to call Tesla again tomorrow...

36A hangs on for multiple hours for you? If so I’ll try it too. 24A is driving me crazy. 36A will only drive me half crazy.

FWIW mine is 18’ too

You know, I just realized that is when mine started doing it too. I was focusing on the wall connector firmware version but it started as soon as I went to the new 24.6.9 car software.

I hope Tesla figures this out. In that thread it sounds like the new replacement wall connector Tesla sent to one of the posters did the same thing. I don’t want to go through the hassle of removing and replacing my unit unless I know that will fix it. The most compelling thing to me is that...

And... it has dropped to 24A. It only took 38 minutes this time. I'm not going to bother resetting to get 48A back but I will watch via the iPhone app to see if it goes the rest of the way to 80% at 24A without dropping further (now it's at 64% and says 2 hr 15 min remaining, ugh). I'll call...

Lol, sorry for the weird smiley at the star of my post. I’m on mobile and can’t figure out how I did that or how to undo it.

:confused:I talked to Tesla today too. They looked up my charger, confirmed it was currently connected to the Internet, said it looked like the firmware was interrupted at some point (?!) and that they were pushing the new firmware. They said not to charge for the next 2 hrs, and to turn off the...

Today I delayed charging until late at night when I could rule out the heat of the day, and I monitored the charge via the iphone app. I was at 53% and scheduled to charge to 80%. It kept up 48A charging for about 50 minutes then suddenly switched to 24A. I had 1 hr 10 min remaining when it...

Created an account here just to add my voice to the others with this sudden “3 blinks” issue on the gen 3 wall connector. Mine has been charging at 48A with no trouble since it was installed on a 60A circuit in late June, then today it gave me the three blinks and automatically cut the charge...
