I took it to a shop that (I think they used the tesla toolbox?) determined that my battery didn't need to be replaced. They fixed the error code and my car works like before. But I have turned off the wifi so I don't get anymore OTA updates.
Did it die after an OTA update? Also, how often did you charge at home vs supercharging?
There are a few threads on here that discussed similar events to yours. I think SC eventually charged for the lower quote since the owners didn't approve the higher quotes.
The narrative has changed from...
@NV Ray @David_Cary -- Here's a list of owners with battery issues from this site. There are similar discussions on reddit, IG, fb, tiktok, etc. A law group that won against Apple for 'batterygate' is looking into this issue.
I'm 100% fine with deterioration over time. At least those owners get to use their vehicles and can pay for a new pack when they feel the price justifies the increased range. They're not forced to make a decision.
I know an owner of a 10+ yrs old Leaf. He says that he gets about 60% of the...
Yes, this is totally sus. Tesla is not the only electric car company with battery packs that are 8+ years old -- not to mention hybrids with much older battery packs. But Teslas are the only vehicles that are crippled unless the battery pack is replaced for $15k - $20k ... and these issues...
My prior service rep knew about this so they just copy-pasted the prior response, even if it doesn't really answer the question. And after working with another SC, I found that the answer is not correct since I had the option to select a new or remanuf pack.
Not all service centers are created equal. Some are downright horrible and unreliable. Contact another service center to get a 2nd or 3rd opinion. Maybe they can do remote diagnostics? If you're in NM then you'll have to go out of state, unfortunately.
I saw a 2017 MS 100D with FUSC and only ~70k miles for $57k. Great deal if I knew the company wasn't going to drop a software update that would reduce the charge rate or make me cough up $20k to fix something. I'm selling mine after all the battery issues. Not hearing good things about the 90D...
I read your post regarding Tesla disabling supercharging 'via a command from the supercharger itself': "Seems even offline cars on semi-modern firmware can now have it perm disabled via a command from the supercharger itself."
If they can do this to offline salvaged vehicles, then they can do...
@wk057 -- Can you confirm or deny that Tesla built in a 'counter' that counts the number of times a vehicle has been supercharged, and once it hits this number the battery maximum charge level is reduced and the code is activated?
From what I've seen, there's more correlation with the vehicle age is than miles.
Once a vehicle is out of the battery warranty (all 2012s and 2013s and some 2014s) they get the BMS_u029 / "Maximum battery charge level reduced" code. It has happened to a 2013 with 30,000 miles, 70k, 75k and...
It's pretty random. Also check out "BMS_u029" which is the error code associated with the "Maximum battery charge level reduced" message.
But it has happened to a lot of people 1) after the battery warranty expired (2013s and some 2014s), and 2) after an OTA update.
Sorry you're going through this.
I'm going to cancel my appt for a new pack (exact same as yours), and sell my vehicle. I'll wait until they come out with more stable products.
Even if it's the DU it's another $10k
**** ... another 10 grand. Hopefully not.
Which code would indicate the DU?
It looks like the BMS codes happened while it was serviced.
The Battery Management System (BMS) will trigger this alert when it senses a loss of contactor power while the contactors are closed. The BMS...
Similar situation with me except my MS 85 is still working but only charging up to 85 miles (thankfully). You can definitely sell it but you'll prob get low to mid twenties for it.
Some questions: Is yours an 85? How many miles? Did you do an OTA update recently? Did the SC share with you the...
If you logged into your account and you can still see the SC01 code then it's a good chance you will keep it. Was the car registered under the dealership or the prior owner's name? It's unusual for a dealer to offer a Tesla with FUSC because it usually gets removed once it's sold to a dealer...
I had to go to another SC to get someone to respond to my request. My initial SC said that they don't sell remanuf packs -- go figure.
Your battery is still under warranty, correct? My understanding is that they are putting in remanuf battery packs for warranty work. And it won't extend your...
There are over 40 others (including myself) on this site that experienced battery issues on their 2013s after the warranty period expired ... many after an OTA software update. I suspect we'll see a batch of 2014s with the same issues after their warranty expires.
It would have been nice "if Tesla added detection checks or additional diagnostics in the newer firmware" during the warranty period. But that would have been expensive for them. :-) No fun doing that.
My only warning was "Maximum battery charge level reduced". I was surprised that they wanted to replace the 12V because it was the last service performed at the same SC. I got the "Schedule service. Low voltage battery needs replacing" warning in August 2022 and that's when I replaced it. (They...
I thought it was broader but after reading it again, it looks like it's related only to that period. Thanks.
(bolded for emphasis)
Release of Claims 1. As of the Effective Date of this...
My app says that the estimate is outdated, contact the service advisor ... I'm asking my SC for a quote on the refurb battery and they give me the same canned response: "We do not pick what pack or part number we use it is up to the distribution center ..." Hope that's not the case.
They're quoting me $18k and the pack they're referencing (1014114-00-D) is my current original 85KWH pack.
When I asked them if I can receive your price and battery pack (since I also have a 2013 MS 85), here's their response:
