    I live in the Bay Area. I decided to take a Road Trip with my wife to Los Angeles, spend a day or two as tourists, then return home. We ended up skipping the tourist part due to Supercharging problems.

    We arrived in Los Angeles with only 40 miles of range left and went to the Hawthorne Supercharger. Driving down from the Bay Area I used the Superchargers at Harris Ranch and Tejon. They worked fine except for stopping about halfway through the charge. Reinserting the Charger plug allowed them to complete the charge normally. I added enough miles each stop to safely take me to the next supercharger.

    At Hawthorne, it was 7 am Wednesday when we started trying to supercharge. We managed to add 100 miles of range, then could not get charging to work.

    Our goal was to add 200 miles of range, so we could tourist in LA for the day, then have enough range left to return to the Tejon Supercharger on our way home.

    Charging Problem Description:

    I plugged into the Supercharger at the Hawthorne Design Center.
    It started normal charging, adding 100 miles range.
    Then the charger stopped charging.
    I then had 140 miles range.
    I plugged in the charger again.
    The displayed voltage rose normally into the mid 300s.
    I heard some electronic "clunking" sounds.
    The display shifted to say the car was charging.
    But Amperage stayed at zero. No charging was occurring.


    A nice Tesla employee, at the Tesla Design Studio tried to help, getting the factory to watch the car's log each failed charging attempt. We tried several charging stations, powering off the car, etc.

    After 3 hours of trying we gave up, and drove to the LA service center.
    We spent 3 hours there slow charging while waiting on feedback from the log analysis of our failed charging in the morning. Without resolution of the problem, we decided to return home and let the Fremont Service Center look into the problem.

    Not knowing if my car was at fault, or the Supercharger, planning the return home took some care.

    We decided to drive to the Tejon Supercharger for one last supercharger try. If it failed, cross over to the 70 amp J1772 charger at Rabobank in Santa Maria, and take the Rabobank run up 101 to the Bay Area. Some Rabobanks along 101 have 70 amp J1772 charging.

    But the Tejon Supercharger worked, so we went on to The Harris Ranch Supercharger.

    At Harris Ranch the problem occurred again. We had just enough range to get to Gilroy, but didn't have enough range to get home. If we couldn't supercharge in Gilroy, then some SemaConnect J1772 chargers were there to get us enough charge to get home.

    In Gilroy the supercharger worked. Being tired, I charged just enough to get home, and returned home.

    I don't know if the Superchargers are at fault, or my car's software, or the car's hardware. I'll let the Fremont Service Center decide on what needs to be done.

    I guess the lesson I learned is not to take ambitious road trips until many others have ironed out the problems. And if you do take one, be sure you have a patient wife.

    thanks for your post. This sounds like an issue with your specific car since others are apparently having no issues. Let us know how it gets resolved. Thanks!

    Did you call the Supercharger support number? Curious if it's live answer, what they might have said.

    so the factory is aware of the problem and working on it!

    Thank you very much for going through the early-adaptor process(-pain) and helping Tesla to figure things out. Let's hope this remains a not so common experience, and that it can be resolved completely, soon.

    These failures calls me for a suggestion that as a fall back option each SuperCharger station need to have at least 1 or 2 HPWC .. Any thoughts ? If supercharger charging fails . We can rely on HPWC charger to reach next destination .

    I would have ultimately called the Tesla support number if I hadn't been sitting in front of the Tesla Design Center. I think Tesla employees there are trained to be helpful. Several people walked up to volunteer suggestions. I figured one would call their pal at the factory, and get me insider support, rather than standard support.

    Plus I have this silly, "I can figure it out without help" mentality. My wife, on the other hand, quickly asks for help whenever problems occur.

    I might know a few people like that ... :). I'm more like your wife, I think. But my son has pointed out my tendency to just take off cross-country and 'figure it out as we go'. It's more fun that way!

    Thanks for replying back. I'd seen that you'd gotten people at the Design Center, but didn't know how much they'd actually know about the SC. It's good they called the factory and helped to troubleshoot. I was just curious if the support line was 24 hour or not.

    That is the value proposition for the HPWCs at the Supercharger locations.

    I didn't realize there was any other way.

    As well as making those sites useful to Roadster drivers.

    And people that opted not to get Supercharger support.
    And people that opted for the 40 kWh battery.

    I've used the Superchargers four times now, thrice without a hitch. But the first time I attempted it just didn't want to go, or would start and then disconnect. Tried a different charger, and it had similar behavior. So I hit the standard/range mode button, because I figured I changed the mode since last charge and maybe that got the car confused.

    That seemed to work.

    Dunno why. Maybe it was just charger wasn't connected quite right the first few times too. I would've rebooted both consoles if that didn't work.
