    HW4 auto wipers seem drastically improved

    After a few days of no stop rain in a new Model S with HW4, it seems the auto wiper behavior has been significantly improved from what I’m used to in 2.5 and dare I say on par with my 2016 MS with an actual rain sensor with the mobile eye suite. This was an improvement I wasn’t expecting and a...

    Temperature sensor faulty? And noisy heater?

    This week the UK has been cold….approx -3 to -5 degrees C However, my M3 Standard 2022 says that it is -13. Eventually (like 30mins post driving) it gets to the likely real temperature. anyone else seen this? Also, the car heater makes a much more audible noise - even on fan setting 2. Again...

    Model X Trunk won't latch- Any ideas what it could be?

    2018 Model X P100d So there I was, at my daughter's hs track meet, which is over 100 miles from home. I get an alert that the trunk is open on the Tesla shortly after we arrived at the meet. I thought "that's cool", I will just close it on the app. I didn't recall there being any issues when we...

    Notifications are telling me the trunk is open when it’s closed

    My notifications are telling me my trunk is open when it’s closed and the automatic opening does not work anymore. I have to manually open and close it. When I hit the button it just beeps. Please help.

    21 MYLR TPMS

    Do I need to spend the CDN125$Each for Bluetooth TPMS or can the much cheaper MHz-based options work with 2021 MY? The shop I ordered from tells me they won’t work.

    Front Bumper Accident

    Only had my M3 SR+ for a little over a month and I had a guy back into my front bumper in the parking lot. Saved the dash cam. Got his info. All looks fine except a little bend in the front license plate (not the car just the plate). I want to get it checked out, but other than physical...

    2018 Model 3 LR RWD Parking Sensor Harness

    Long story short, I bought a used July 2018 Model 3 in August 2020. I live in Central KY and we recently had a lot of snow and ice. After I cleared my car, one of my front parking sensors died. I bought a new sensor and replaced it myself with no luck. Tesla Service came to my house today to...

    2020.20.12 Vanishing cars?

    Hi folks, Installed my first update since getting the car last night went from 2020.11.103 to 2020.20.12 and I did notice something odd today when I went driving. The sensors no longer pick up cars in front of me or front sides when standing at the lights. When the cars drive away maybe 30 feet...

    OEM Suspension Position Sensors

    I swapped out the springs in my 2020 3LRD yesterday and noticed that it has suspension position sensors on the left hand side, front and rear. None on the right hand side. I haven't seen these mentioned anywhere yet, and I'm curious about what they would be doing. My theories are: - Monitoring...

    Group Buy for Power Trunk/Frunk Liftgate! (Round Two 10-23-19 to 10-27-19)

    Hi everyone, I organized the first group buy for this power liftgate automatic open/close the trunk, the frunk, and foot sensor for the Model 3. It was a huge success, and I received a lot of requests to do another group buy for these kits. Trunk: Frunk: Model X & S Frunk...

    Group Buy for Power Trunk/Frunk Liftgate!

    Hi everyone, I found this video from i1Tesla about the power liftgate for trunk and frunk for Model 3. I'm aware of the Teslaoffer product. However, this product seems to be much better in price, simpler installation, features (can open/close from the screen besides app and fob), and does...

    Speedometer Sensor

    Does anybody have an idea where the speedometer sensor is installed? Is it on the front or rear wheels? I’m asking because I plan to get different size tires for a staggered setup but I don’t want to change the speedometer readout by a significant amount. I’ll be getting the correct size tires...

    Sentry mode turns off

    I don’t use sentry mode much. Twice out of a maybe 5 times I have used it, it has turned off due to “sensor error”. Both times it was for an extended period of time (over night). This happened in 2019.24.2 and 2019.28.3.1. Anyone else?

    Tesla Model 3 sensor and accident

    Otherwise I love this car. Body shop says the following damage has become quite common lately. I guess people are getting too dependent on these sensors. Just ran into a high curve on the passenger side while getting out of the parking spot. Sensor on the right side gave no visual or audio...

    HW and SW Redundancy in HW3

    Today in a tweet, Elon Musk eluded to hardware and software redundancy coming. He then further clarified a question about how this will work: A few questions come up as I think about this: 1. Will each SoC run identical versions of the OS and NN? - If so, will this potentially open...

    Front Bumper Issue After Sensor "Recalibration"

    A week or so ago, I had the autopilot engaged while in stop and go traffic on an interstate. While stopped, the warning chimes suddenly kicked in along with the flashers and the car did not start moving again with traffic. I was able to take manual control after a few panicky seconds but I was...

    #12 sensor failed

    Just got the 2018.26.1 at SC and tried Summon for the first time. Every time I pressed Forward or Reverse, the car would start trying by making noise and turning on the lights. However, it stopped before making any move. I called the Service Center for this issue. The rep checked the log and...

    Radar sensor failure

    Has anyone with one of the longer-range radar sensors used for ACC had any trouble with it operating properly? Are there any situations in which you have noticed that the radar sensor's data cannot be accessed or the display panel outputs an error message regarding the radar? I have heard that...

    Failure modes of radar sensor

    Hi everyone, I got my hands on a Bosch mid-range radar (MRR) sensor that I believe belonged to a model S a while back. Now I'm working on a school project where we try to get the sensor to fail (i.e., output wrong or unusable data). Those of us involved in the project have defined a goal of...

    Improving the Tesla Model S Alarm

    Back in 2005, I installed a shock sensor to the hood latch alarm of my old Infiniti FX35AWD primarily because the alarm in my old FX (like my Model S) only activates when a door, frunk or trunk is forcibly open, not when there is substantial motion detected. With the help of a friend, we...

    Front Bumper Sensor Damage by a Rock Chip Park Assist Unavailable/Disabled

    This morning I noticed the following message in my 2017 Model S. “Park Assist Disabled” and then sometimes changes to “Park Assist Unavailable”. I called the SC, they said they would look into it and get back to me. After a few hours I didn’t hear back from them, so I looked over all my front...

    New sensor in Falcon Wing doors. No more bruised heads.

    I took delivery of my MX this week and while going over the car I was told about a new sensor that is now built in to the interior of the Falcon Wing doors. The sensor checks if anyone is present underneath the door prior to closing. I have tested and can confirm that it works. Before I...

    FWD Sensor issue

    A couple days ago my passenger side FWD sensor started acting up. Now there is a permanent obstacle detected on the screen. It even follows the door up when opening. The driver door and FWD barely open now because it thinks there is an obstacle no matter where I am. Do I need the sensor...

    Can I disable the driver seat weight sensor?

    When backing up, my S constantly shifts from R into Park! Turns out it's because I'm lightly lifting my butt off the seat to turn and see what's behind, which my S takes to mean I'm no longer there and "Whoa - gotta emergency park!" I understand there's a hyper-sensitive weight sensor there...

    Wiper Anomalies

    So, I’m patiently waiting for the rain-sensing to be enabled on my HW2 MS. I’m spoiled by having that feature on my 17-year-old Porsche. How tough could this be? Didn’t they verify that they could detect rain using the front-mounted cameras before they got rid of the IR rain sensor? Maybe it...

    Sensor interactions with wraps such as Xpel?

    A birdie hinted that wrapping my upcoming S in Xpel is NOT recommended because it would somehow interfere with the sensor suite. And here I am planning to do a full body wrap on my new S in December, plus tinting on all glass -- sunroof, rear window, side windows and, if Maryland will allow it...

    Driver's Seat "Sensor" is No Bueno

    So, the sensor in the front seat--the one that tells my X that I am in the front seat--is "broken." Apparently, my car thinks I am in the seat when I am not--and vice versa. The SC have decided to just replace the entire seat. The wait? 6-8 weeks minimum. I got my entire car delivered inside of...

    Model S decides to halt while backing up

    I'm wondering if anyone else has experienced this. I was at a Nissan dealer and they were going to let me charge on their J1772 for a while. There was an electronically-controlled gate, which they opened for me, and I was going to back up through this (very wide) road to the charger location...

Has anyone seen a list of Sensors that must be built into the Model S? There must be some simple sensors...
