    Events unfolding quickly. Left. Harris Ranch 30 min ago and headed S to Tejon. Nav abruptly rerouted at this point back to Harris. No message to slow down or charging required to destination. Just abrupt U turn required.

    reset Nav to Tejon and removed all chargers. Says we will make it with 11% so I'm thinking fine no problem. Then it abruptly rerouted us back to Harris again. What the hell is going on? Making me very nervous.

    avg 346 w/mi. Left Harris with 30% buffer. Still have substantial rated range buffer.

    Don't worry about it. These are the crappy nav issues that have been discussed before. The Trip Planning stuff does this a lot; I've had the same experience when doing the jump between Harris and Tejon - the software insists on making you go back.

    +1 to what GG said, I had the exact same thing, and I left with a healthy reserve, but for some reason it kept telling me to turn around and go back.

    I've had this happen to me in similar circumstances.
    The nav system needs a lot of work.

    It's been a long time since the trip planner was pushed out (to eliminate range anxiety) and I wonder when we will see it fixed?

    FWIW, ended up arriving with 29 miles. So not even a close call.

    I arrived with 56 miles when it was telling me to go back to Harris ranch, I was really nervous since it was my first road trip.
    First and last time using teslas nav when on a road trip

    Tesla Nav = pretty darn bad. Unfortunate. A phone is better. Hope they up the game soon.

    at this point in ownership and having taken many long distance trips I know my car's capabilities and limits and I never use the nav trip planner, ever. The only time I ever came close to not making the next SC was weather and a poor decision.

    This is a known issue. Current version routes you through superchargers every time you will have less than 20% at destination (if I remember correctly). You have to tap on the trip panel then "remove all charging stops" from the trip. After that will you will have a fairly accurate estimate of the charge remaining. You will only have to turn on the energy app and watch on the trip panel how well you are doing, then adjust your speed if needed.

    First time I had this, the Nav was trying to take me to the supercharger in Albert Lea when I was in front of my destination in Rochester. It also told me I will not be able to make it :tongue:

    I had the same issue over the same route. But like others here, I knew the route well and knew how many miles of rated range was enough. What's unfortunate is the trip planner signals your phone app that you have enough charge to reach your next stop along your route and then freaks out 10 minutes down the road and tells you to turn around.
    On this same trip, after I ignored the warning and the "%charge remaining at my destination" crept into positive territory, the nav correctly routed me off I-5 for a short distance to avoid a long stretch of "red" where construction had severely slowed traffic.
    So, I haven't stopped using it completely. It's like having a friend navigating when they've fallen off their meds. Hardly the "end of range anxiety" but manageable when you've got things calibrated.

    ^^This (I can’t emphasis this enough.. it’s very helpful)

    The trip planner will also have difficulty getting an accurate usage projection at the beginning of each leg of the trip, but that usually settles down once you’re on the freeway for 5-10 minutes.

    I agree. I usually set my destination to the next charging stop and use the "Remove all charging stops" option. Then the Trip Planner energy graph gives me a very accurate estimate of my energy use and I can adjust my speed if necessary to make it to the charger. The Trip Planner graph is very accurate and makes continuous adjustments as you drive. It usually starts out a bit conservative but quickly adjusts to your speed, terrain, temperature, etc. I like to have about 10% left at the end of my trip as a buffer.

    I recently did a route and it has been charge for 15 minutes at one SC and then another 27min at the next SC.

    Not sure why it just didn't have me charge for 42 min at one or the other.

    The trip planner is still a beta is it not? I turn it off as it's still very fubar. It's no good for planning trips:)

    That's rather odd behavior even for trip planner.

    I'm used to the re-routing back to where I just charged from. But, I'm not used to it doing it after I've removed all chargers.

    If it did what it did to the OP to me I'd turn trip planner off.

    Same issue here. First time doing that route so it was annoying. I cruise controlled the whole way @ 75mph, but if I would have known better I would have gone faster. BTW the whole way it was telling me to cross over to Fremont SC (30 minutes out of my way) which was really really annoying.

    I have found the same.
