    My two year old Tesla 3 mid-range navigation is unreliable.

    January 5 I tested positive for the Coronavirus and had to drive to a hospital, feeling pretty crappy, to get antibody treatment. Nav took me way out of the way and it took nearly 1.5 hours to drive there. It was right off the Garden State Parkway. Going home I took the parkway and it took an hour.

    A month later in Brooklyn, Nav wanted me to drive through Manhattan to get home. Waze took me through Staten Island and saved nearly 30 minutes.

    Last Saturday I had to navigate to a Supercharger in a mall in Deptford, NJ. It's in a shopping center on the corner of a busy intersection. Nav sent me to the diagonally opposite corner... I had to drive around guessing where it might be.

    I made an appointment at the Tesla Service center which they cancelled because they claim it's all on Google Maps... I'm not happy at all with this... anyone have any ideas?

    Check your nav settings. Dk you have it set to avoid toll roads like the Parkway?

    Do you know a navigation service that is 100% (not 99.999%, but 100%) accurate?
    Also, speaking of traffic, do you have live traffic subscription in your car? If yes, then it's Google issues. The maps in Tesla are by Google anyway, so the Tesla service is correct. It would be your car issues only if you find the map shows your current position not where your car actually is. Everything else in navigation has Google algorithms as the base software.

    The navigation definitely has some glitches. There is a spot in town where the directions list a left exit (with the line drawing indicating not to take it, but who can look at it that closely while driving) even though I’m supposed to stay on the highway then it switches to taking the highway just as you get to the exit. It seems the map information is just incorrect in some spots.

    I take a long drive regularly that is a straight shot on the freeway. Once, the navigation told me to get off the freeway to drive down back roads before returning to the freeway at two different locations that were not necessary. I think that was due to old traffic data (accidents that had been cleared but navigation was routing me around).

    Unfortunately they are correct. The Tesla maps are really Google maps, and there is nothing the service center would be able to do about it.

    Happened to me several times, and not just in Tesla.

    Maps are Google but the actual routing is not. It's a vendored and tweaked product to my understanding.

    The nav routing is definitely not good in comparison to any other common offering, but a service center won't be able to do anything to "fix" it.

    One of the biggest failings is not providing route options, which I've had in every GPS system I've used over the last dozen years. Even Google maps suggests three optional routes. One way to get another option is to ignore the routing for a while and force a recalculation.
