    Failed Model 3 HV Battery - Out of Warranty - DIY

    Thanks everyone. As a quick update, the car is still doing great nearly 2 years and 25k+ miles later. CAC imbalance is around 3 Ah, Max CAC is 204 Ah, internal and external isolation is still great (≥4500 kOhm). No issues with the car whatsoever, aside from a deer I hit in June (and the car...

    TESLA MODEL S stopped working... CAR MAY NOT RESTART

    Can confirm that these messages cleared BMS_w172 after I repaired my rear drive unit and verified good isolation. Thanks Jason!

    Failed Model 3 HV Battery - Out of Warranty - DIY

    Not particularly. The car was never a salvage title and honestly I'd say it's just as safe to work on as any other Model 3. Regardless, they could easily (and maybe do) track this battery replacement as having been done outside of a service center, but disabling cars for such a repair would be...

    Failed Model 3 HV Battery - Out of Warranty - DIY

    The only thing needed was a software update (or reinstall) to match the BMS and PCS firmware with the rest of the car. I am not sure what would be necessary in alternative scenarios like using the original high voltage controller or PCS, but I think it would mostly be the same, a firmware...

    Failed Model 3 HV Battery - Out of Warranty - DIY

    Sorry, I just saw this. It leads to the DC charging busbars. It is easily removable.

    Failed Model 3 HV Battery - Out of Warranty - DIY

    So far it's doing great. I plan to provide a more in-depth update after a longer period (probably after a year) but essentially: Driven 7,500+ miles, multiple road trips (probably 10-15 supercharging stops total), reaches 250kW and tapers like normal, rated range fluctuates around 303 miles...

    Vendor Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

    As usual, thank you for being such an informative and contributory resource about these packs. My P85D (660XX) was made in late December and the AC condensation line definitely dumps directly onto the pack fuse cover (genius ideas all around, it seems). It sounds to me like the umbrella valves...

    Tesla changed the warranty for vehicles 5 years ago. See Vehicle Warranty Older vehicles have the 8 year warranty you mention.

    Failed Model 3 HV Battery - Out of Warranty - DIY

    Once the lid was sealed and installed, I was able to start putting the penthouse components back in. Honestly, the penthouse is a beautiful work of engineering. The only thing that scares me about it are the PCS coolant lines, because a leak from those would probably be a bad time, but they are...

    Failed Model 3 HV Battery - Out of Warranty - DIY

    Wanted to provide an update since it's been over a month and some progress has been made. The pack I bought had damage to a coolant port at the front that would require lid removal to repair, and some heavy scratches and dents to the bottom of the pack casing. Not sure how much of it was from...

    Failed Model 3 HV Battery - Out of Warranty - DIY

    The four modules are in series, as are the 23 or 25 bricks that make up the modules. The 46 cells in each brick are in parallel.

    Failed Model 3 HV Battery - Out of Warranty - DIY

    No, but I honestly don't expect to get much from that. Maybe $2-3k. Car was $23k, battery was $9k, shipping and taxes added up to $3k. Best-case is probably $32k and many, many hours of learning. :) This is not a solution, unfortunately, as explained above by @wk057 - anything short of entire...

    Failed Model 3 HV Battery - Out of Warranty - DIY

    Just wanted to give a quick update on this. @wk057's company had a battery that was cheaper than Tesla, but I ultimately went with a LRRWD pack I found on eBay for $9,000. Using dimensions from the old pack and some wood, we made a battery stand that raises the pack above the wheel wells of our...

    BMS_w035 alert popped yesterday and this morning

    I recently got those, too. They are HV isolation errors. It could be your battery heater going bad, especially if it was in the cold and the heater was on, otherwise it is likely to be an issue with your drive unit (either connector or internal). Either way, the car thinks that HV might be able...
