    Kevin Sharpe's decreased Roadster range

    Just as we start asking Roadster owners to provide logs that could help prove my case (or not) you feel the need to start moderating posts... make it difficult if you want but it will not stop the bigger story because it's important to consumers.

    I would also like everyone to know that my posts are being moderated... part of TMC's attempt to control negative Tesla news no doubt.

    Make me a public offer... no need to keep this private. For the record, Tesla offered me 35,000 GBP (57,000 USD) for a trade in against a fully loaded P85+ which has an OTR price 99,730 GBP (162,550 USD). - - - Updated - - - That's hardly the point...

    Kevin Sharpe's decreased Roadster range

    Tom Saxton has confirmed that "the [PiA] survey doesn't collect log files, which is what would be needed to create more graphs like that". Therefore, I'm going to need log files from more Roadsters. Who on TMC is prepared to share their logs to prove this point? Feel free to PM if you wish to...

    We'll also need to factor in the 20% pack replacement somehow... hopefully everyone here has contributed data to the PiA study :smile: Anyway that will have to wait until next week... three electric car events this weekend :rolleyes:

    ok, I'll ask Tom Saxton what data is available in the public domain. If we can't get the PiA data then maybe everyone here would provide their logs for analysis.

    Kevin Sharpe's decreased Roadster range

    OK, can you provide logs for more Roadsters with 50K miles? Or would you be happy with logs for cars with less miles? How many cars would be a reliable sample size in your opinion? The 154 in the PiA study?

    Kevin Sharpe's decreased Roadster range

    DieAbetic remember my relationship is with Tesla UK and therefore any legal proceedings will be conducted under UK (EU) law. Personally I think it's critical that we discuss these issues as Roadster owners because we are the ones who can't get the spare parts and ultimately everyone will face...

    Kevin Sharpe's decreased Roadster range

    Yeh, many here seem to have a blind spot to what's really impacting the cars range. I agree, this makes no sense... we do know that all important decisions are taken at Tesla HQ in the US not in the UK, and I guess it's possible that my battery issues just fell through the cracks. Indeed I have...

    Kevin Sharpe's decreased Roadster range

    No, as I said before, I had 32A charging at the original destination and could charge there during my visit. This negated the need for range mode charging unless I was unable to spend enough time at the destination. You really are focusing at the wrong period... look at the state of my...

    It's an opinion based on the work being undertaken behind the scenes. Clearly some people on TMC have also raised questions about the battery as delivered. Here's are a couple of the most recent; Kevin Sharpe's decreased Roadster range - Page 37 Kevin Sharpe's decreased Roadster range - Page 38

    Well, that's the fundamental problem and one that will need challenging in court I suspect.

    Agreed. For me it's closer to 5 minutes from a full range charge to driving (no reason to leave it longer with OVMS). - - - Updated - - - The problem with that strategy is I don't drive everyday because we can walk and cycle and prefer not to use a car unnecessarily. - - - Updated - - - You...

    Kevin Sharpe's decreased Roadster range

    My guess is something like 30 times on my regular trip, and maybe 20 more times if you include the trips to events like Tesla To Geneva, WAVE, and LEJOG. If by "deep discharges" you mean into the bottom 10% (where car stops calculating range) then I believe that is now 4 times in total. I...

    Kevin Sharpe's decreased Roadster range

    My first use of 'range' mode was when driving with a Tesla representative in July 2010. I do not have a definitive answer to your question about how often I've used range mode which is why I can't provide a meaningful answer to your question. I said previously that in 2010 I used it a few times...

    Kevin Sharpe's decreased Roadster range

    No, I expected my battery to be good on day one (it was not), for the repairs in 2011 to make things better (it did not), and for degradation to be consistent with other UK Roadsters (it is not). Look again at my OP and the recent graphs I posted... the range is falling off a cliff at 55,000...

    When will a ~400-mile Roadster pack become available from Tesla?

    That got my vote as well... I think Elon's statement that it "will be done this year" is yet another Tesla fantasy.

    Tesla Motors current and future battery degradation warranty...

    But that's exactly what I want as a customer... the knowledge that when the worst happens I will be ok... if I purchased a Nissan I would know that a 30% battery degradation would trigger a battery repair. I don't think most Roadster owners expect a warranty to be applied retrospectively, but I...

    Owner 2 has driven more than 60,000 miles and is in a slow decline, I've driven 55,000 miles and I'm in a nose dive. Personally I think this is very significant.

    Tesla Motors current and future battery degradation warranty...

    My battery was faulty on the day it was delivered and despite a repair by Tesla has continued to degrade. It's a great example of why customers need a degradation warranty because relying on Tesla's good will is not enough for most people. If I had purchased a BMW or Nissan then I would know...

    That's a legal interpretation of the ESA and based on my communications with Tesla I have no reason to doubt it. - - - Updated - - - Was I ignorant to trust that Tesla would delivered a 'working' product and maintain it during the warranty period? Can you see any difference between the three...

    Kevin Sharpe's decreased Roadster range

    Correct, and my next range charge will be lower than 199 miles because my CAC is now 127.65 (and dropping every time I drive the car). The fundamental issue here is we are looking at the battery today and arguing about whether it's within the limits of some blog post that Tesla wrote. In...

    Tesla Motors current and future battery degradation warranty...

    Nope, Tesla are no longer regularly replacing packs on the Roadster, and according to their 'warranty' are under no obligation whatsoever to replace packs regardless of the degradation. For me the fundamental issue is that Tesla use the term "infinite mile warranty" knowing full well that it...

    Kevin Sharpe's decreased Roadster range

    This trip was driven in range mode and OVMS is reporting what 'remains' in the battery... in my experience it is extremely accurate... indeed if it wasn't I'd have been dumped on the side of the road last night because the reduced car range almost caught me out (I had to slow down to 50MPH while...
