Steering on the Model X

edited November -1 in Model X
After the second to last update, the steering on the Model X seems "glitchy." I know that's a great technical description, but sometimes when driving on city streets or on the highway, the steering feels as if it is on Autopilot. Similar to Autopilot, there is a tension in the wheel and you have to muscle it for control of the vehicle. The problem is that Autopilot is not engaged, and the Autopilot functionality has been turned-off on the control panel. This happens periodically, and it happened after a reboot and the most recent update.

Has anyone else experienced this issue?

    It sounds like you have Lane Departure Warning on? It will vibrate the well to alert you of a possible lane departure. You can turn the feature off.

    ...vibrate the steering wheel...

    It is not the lane departure warning. This happens on subdivision roads with no lane markings. Also happened on a single lane, dirt road.

    What I am talking about is akin to power steering failure (happened to me on an old Pontiac in the 80's), and moving the wheel is itself a struggle. But with the Model X, it becomes very difficult to steer, then a few minute later, all is well.

    Isn’t there an update to Lane Keep assist where it tries to keep you in the lane?

    As for lines, Tesla’s can make lane lines out of marks on the pavement (patches, etc).

    @TeslaFred - sounds like a service call issue. There was an issue with power steering dying back in late fall of '17. My MX suffered from this problem and it required a manual reboot to fix. Meaning the 12v system needed to be disconnected and the vehicle rebooted from zero power to fix. I'm pretty sure this was something that just impacted a small number of MXs that were early AP 2.5 hardware builds. There has been a firmware fix in place for this issue for a long time. But maybe there's been a new bug introduced that impacts your vehicle?? But it sounds like a safety issue that the SC will address quickly and you shouldn't need an appointment to get attention for.

    Bob - Thanks for the information. I'll call the service center, again.

    Oh! The old line rail voltage mismatch problem. I remember that.
    It can be done in the field, but it’s better if it’s done in a service bay.

    Same thing is happening to my 2017 Model X. It feels like the power steering is losing power on big turns. And it also feels like you are pushing against the auto pilot. Whatever it is it takes more effort to Ruth the steering wheel. Solutions?

    I am having this same issue with my Sept 2017 Model X. I hate that I cannot get a service center appointment for 10 days from now. Plus, you cannot even speak to the service center directly any more. Unfortunately, I will not be able to drive my X until it is fixed. I'm afraid it will not turn properly and I will get into an accident.

    When I have a service appointment, I try to find time to go in for a "pre-service visit" and just park nearby, and walk over to the service techs and when they are not so busy, I tell them I have an upcoming service appointment and these are the issues I am having and what do I need to do to prepare for the visit? Almost always they will be interested and ask a few questions and even walk over to look at your car and give advice. Give them as much information as you can, then politely wait and answer their questions, they are pretty knowledgeable, and can enter data and your concerns into the appointment. I have had service techs then contact me by email or text message and ask questions, they can upload data from your car and look at the logs and can decide what to do before the appointment. It seems to make my rare service visits smoother.

    I have the same issue on 2016 X 90D. It's gotten a lot worse over the last two weeks and my wife flat out refuses to drive it now. I took into SC yesterday and they think that I-shaft (???) is at fault after a day of triage. The half-shafts on it have been replaced 3X or 4X since we purchased but I've never heard of the I-shaft. Thoughts?

    The complaints about steering sure sound to me like Lane Departure: Assist is turned ON. This is also evident in the driver's display, which shows when the lane boundary being crossed in red, without a turn signal.

    I had the same steering issue with my 2017 90D MX 2 weeks ago. It felt like the power steering had failed/fighting against the auto pilot. I phoned roadside support who were very helpful as always. We reset the car over the phone by powering it down through the Safety & Security Menu as they thought it was probably a software issue. There was no change after this so it went away on a flatbed (for the 4th time) and it was diagnosed at the service centre as a mechanical failure of a Universal Joint which was replaced under warranty the next day and is now driving as good as new. I've had a lot of issues with my MX, not sure if I've just been unlucky but when it works I absolutely love it.
