    Tesla needs better Customer Service to survive.

    This is long but I think pretty important. I had my battery pack go out 2 days after I bought my used 2012 model s and ended up going through RECELL to refurbish the battery and things were great for a couple months... I sadly had a fender bender 2 months ago, and the "Tesla approved" body shop...

    For DIYers: adding distilled water to dead OEM 12v batteries

    Some OEM lead acid auxiliary batteries on older Teslas seem to completely rejuvenate with the addition of distilled water -- the same as with many lead acid batteries. I first learned this with my previous car -- a 2004 Prius -- which had a very user-serviceable auxiliary battery. I was about...

    "A" Pack upgraded to "D" pack - slow supercharging

    Not sure where to post this exactly. My 2012 S 85kw "A" pack was replaced with a "D" pack. Yay me! (Thanks Tesla!!) When I supercharge I never get close to 90Kw let alone 150 or 250 Kw. Did Tesla forget to flip a virtual dip switch? Is my 2012 too old to support higher charging despite the...

    Range-Loss Related to Heat?

    My 2019 Dual Motor M3 never had the 310 range I was promised. I started at about 305. It dropped to about 284 (derived from the Stats app) by 60k miles. This seems like a standard drop, from what I have read. But just in the last two months, it went from 283-286 or so, down to 274 almost...

    Before work I pull into my local charger next to a Taco Bell I watched a mobile technician from some random company change this other guys 12 volt but he never disconnected the 400 volt and I stopped and asked him about it and he says it's "recommended" not "required" What could happen ?

    Power Drain (continued)

    This has probably been discussed a lot before, but I’m new to the club so wanted a clean start! I left my Model 3 with an off-airport parking service for 10 days. It was driven away with 202 miles range and returned with just 60 miles. It had only been driven 16 miles to and from the car park...

    Installing smoke detectors and other safety devices for battery packs

    Reading about exploding Bolts and melting wires, seems to be prudent to install smoke and fire detectors close to where battery packs are. And a AFCI circuit breaker if not already. I doubt any home garage has a smoke detector, not required by law, should it be?

    Is it okay to discharge a battery bellow 20% for a short period of time?

    Hi all, I know the rule of thumb when it comes to SOC is 20-80% and it is okay to go above 80% for a short period of time like before the long road trip when your battery will discharge bellow 80% after an hour or so of driving. However, when it comes to the lower level of SOC, is it okay to...
