Adaptive Cruise Control problems of the 2017 Tesla Model X

While driving CA-17, as is frequently the case, I had to disengage automatic steering several times to correct its poor lane keeping. Much to my surprise, the vehicle stopped maintaining speed, creating a dangerous situation with vehicles behind me as the uphill road caused the vehicle to rapidly decelerate the second I turned the wheel. After experimentation, I discovered that Tesla has completely removed cruise control capabilities from these vehicles unless you completely disable the fsd beta functionality, which makes this vehicle highly unsafe to drive in any environment where autosteer is inadequate, including CA-17. Further, this isn't just unsafe on weird highways. This poor decision on Tesla's part could very easily cause rear-end collisions on freeways. Nobody in their right minds would expect a vehicle to suddenly massively decelerate just because you correct its poor steering. This is just plain dangerous. This so-called "full self driving (supervised)" version needs to be recalled immediately, and Tesla must be forced to make cruise control fallback available regardless of the fsd state. Until they do, it is fundamentally unsafe to allow Tesla vehicles to remain on public highways and freeways with fsd (supervised) enabled.

This is regarding two Tesla recalls: - NHTSA recall number: 23v-838; tc2023-657 - NHTSA recall number: 24v-051 as noted in both recalls, they are to be delivered via software updates. My car is currently running version 2022. 8. 10. 16 7477b4ff8e78 which is clearly lower than the version required for both recalls. I have taken my car to service as my software version is not updating. Tesla has refused to comply with the recall and update the software version on my car. It should be noted, although irrelevant for the recalls, that my car is still under manufacturer's extended warranty, which we purchased along with the car when buying it new from Tesla.

I received a notice from Tesla for recall no. 23v-838 for my 2017 Tesla Model X - p100d. The notice states that I should check if my software version is "2023. 44. 30" or a later release. Unfortunately, the 2017 Model X is on a different update schedule, as it has different computer and sensor systems than newer Model X's. My software version is from 2022. Accordingly, the recall was not remedied by Tesla for my vehicle and all other older Teslas with the prior sensor suite. I checked for any software updates but none was available. At the very least, the notice is deficient, as if they pushed a separate update for older model Teslas, it was not communicated therein. Thanks!.

Mcu1 fsd beta still not working and nothing has been addressed from Tesla. Tesla states we will mcu1 will be supported for fsd.

I paid for fsd and now Tesla has disabled the feature. They have not responded to any inquiries by me as to when it’s going to be reactivated. I would appreciate anything that you can do.

When autopilot is engaged, the car randomly decelerates on the highway. This has happened multiple times. I have tried to report this to Tesla but to no avail. They tell me the following: 1. They are unaware of any issue 2. Then, it is my specific car's problem and not a design issue and they will not fix it without charging me over a $1100 3. When I asked them what the issue is, they said they don't know and want me to provide to the minute detail on when the incident happened. 4. That I should stop using autopilot (which I paid for) because it may be unsafe for me to use. When I point out that their statements are conflicting with each other, they ignore me. I have tweeted about this to elon musk as well to NHTSA and I am hoping that someone will notice this and help me get this fixed.

On the date of January 4th, at approximately 6:50 pm, while using the autopilot feature on my Model X, I was driving 55 mph on the highway and the phantom break occurred, which it completely stopped my car but I was fortunate enough there wasn't any car behind me and I was able to speed up quickly avoid any accident.

Highly repeatable issue: driving on left lane of a highway going at high speed (60) with adaptive cruise control enabled (but * full self drive mode). Put on turn signal to merge into right lane. There was a car in the right lane directly next to me but I had not initiated the merge, was merely signaling my intent to merge. My car slammed on the breaks (very dangerous as I was almost rear ended the first time by a 18 wheeler). Did some testing at a later date- if there is a car slightly ahead of me in the right lane, the car behaves normally (maintains speed) if there is a car in my blind spot, the car indicates there is someone in my blind spot but maintains speed. If I am driving in the left lane all three scenarios (slightly ahead, directly adjacent, in blind spot) the car maintains appropriate speed. It is only when car is directly adjacent when in left lane w/ right turn signal that car always now will slam on brakes. Very dangerous- Tesla has been made aware of the issue 2x now- and had informed me that “it is beta software (?????!!!!!!) and to live with it. ”.

We were driving down the freeway in daytime sunny weather on “autopilot” (I was actively monitoring the vehicle of course) when the car slammed on the brakes for no reason. It was aggressive and fortunately I disconnected the driver assist “autopilot” and immediately pressed on the accelerator (not an intuitive action) to avoid causing an accident. There was no reason for the car to behave this way. Furthermore, Tesla updated the software recently on my vehicle. I purchased the vehicle with radar, whereby it would use the radar as an input in coordination with other information for the adaptive cruise control and auto steer. (collectively called the “autopilot” by Tesla. This recent software update took the radar out of the equation and made my car function differently (less robust) by now only using the cameras and not the radar. The cameras on my model year are not, to my understanding, of the same capability as the cameras that Tesla is using with their newest models. Despite the cameras being older, Tesla modified the vehicle via over the air software update to only utilize the cameras, again, despite the car being designed to utilize the radar as an input to the semi autonomous driving. I take great issue with Tesla retroactively reducing the capability of my semi autonomous driving and not providing a warning or a clear choice. The phantom braking I experienced was after this software update that removed the radar. It’s one thing if a driver needs to be prepared to brake, but quite another if the car brakes extremely aggressively and the driver has to rush to press the accelerator, all while startled. I work as an airline pilot and this seeming total disregard for safety, removal of radar input that the car has on board already, and lack of transparency to the driver would never be accepted in aviation. I urge the NHTSA to look into the aggressive uncommanded braking. Thank you, stefan.

I was driving my Tesla on left line of i75 norh with 70 miles speed. It was on autopilot . Without any warning car lost the control and slipped, changed three lines and collide at the right side median . It’s happened on 3 July 2022. I reported the accident to Tesla right away. The accident took place more than 6 months and still Tesla is saying they are studying the car and not giving a clear report. So the repair people doesn’t know how to fix it and I am out of car. Please investigate the case and help me to get a report so that I can fix the car.

Many instances of hard braking in cruise control with no cause. In the last 6 months it’s gotten very bad. It only happened very infrequently before when someone was turning off the freeway it would brake for just a second. Now it is braking hard in an extended fashion and multiple times in one trip. Sometimes we can see some reason, sometimes not. Once, traveling 75 mph passing a large truck in the lane to my right, the brakes slammed on very hard. Fortunately, I had both hands on the wheel and avoiding crashing into him and the car be him me was far enough back to not hit me. Many other smaller instances, but today doing about 45-50 mph the brakes slammed on hard, didn’t release, and I had to steer to the left and hit the accelerator to avoid hitting a biker. I think the Tesla may have been reacting to the biker. I will not use cruise control any longer until it is fixed. It is terrifying and it’s just a matter of time until something really bad happens.

The vehicle brakes are aggressively applied at random times when traveling on the freeway. This only appears to happen when the vehicles tacc (traffic aware cruise control) is enabled. Thankfully I have not been rear ended yet. My family's safety is in danger when tacc is enabled. Not only am I concerned we could be rear ended, but I am concerned someone could think I am "brake checking" them and then proceed to act violently (road rage). There is a particular stretch of highway where this happens 100% of the time that would allow me to reproduce the occurrence on demand for investigative purposes.

Since installing the latest update (2021. 24. 48), my vehicle is suddenly experiencing: * frequent bogus forward collision warnings (several per day) * instrument cluster outages (black screen) * sudden autopilot shutdowns caused by center display communication failures (mcu) other people with significantly different configurations (e. G. With the emmc repair done, with autopilot hardware version 1, etc. ) have experienced similar failures. This seems to be a very serious software regression that needs to be addressed immediately.

Firmware version: 2020. 48. 37. 8 date of occurrence: 2/18/22 location: i66 westbound description: on i66 westbound near rt123 exit the car was traveling at 70mph and decreased 50mph. The car was on full autopilot. Set speed limit changed from 70 to 50mph but signage and the car's perceived speed limit was 55mph. No cars ahead of me to initiate the rapid deacceleration. The occurrence happened between 8 to 8:15am. Weather was partly cloudy. Second occurrence of rapid deacceleration occurred on the same commute. On i66 westbound near rt50 the car was traveling at 70mph and the vehicle decreased speed to 30mph. The autopilot set to 70mph and rapidly deaccelerated to 30mph. Cars ahead were several car lengths away. No braking or deacceleration was observed by the cars ahead. The occurrence happened between 8:15 to 8:30am. Weather was partly cloudy. Note, this issue has happened multiple times over the last 6 months. Didn't realize that this issue was reportable. Rapid deacceleration is fairly common event and has been observed on i66 (both directions), i95, rt28, rt29, i70, and i270.

While on autopilot at highway speeds, car randomly and suddenly brakes rapidly for no reason. Happens during day, at night, on different roads, in different conditions. No warning lights or alarms.

Tesla full self driving fsd is too dangerous for public street experiments. The video evidence is not from my vehicle but mine does sudden automatic unexpected swerving the same way: twitter video shows the automatic system swerved toward a bicyclist and the driver was able to grab the steering wheel to manually abort the system. This automatic system with numerous close calls should not use the public as dummies for testing. Https://twitter. Com/taylorogan/status/1491224700303060992?ref_src=twsrc%5etfw%7ctwcamp%5etweetembed%7ctwterm%5e1491224700303060992%7ctwgr%5e%7ctwcon%5es1_&ref_url=https%3a%2f%2fteslamotorsclub.

Tesla full self driving fsd is too dangerous for public street experiments. The video evidence is not from my vehicle but mine does not recognize many obstacles that increase the risks of collisions: the youtube video shows the automatic system failed to recognize the green bollard and even with the quick intervention from a claimed well experienced fsd driver, the car collided with the green bollard. The public should not be forced to be at risk for allowing this automatic system with numerous dangerous behaviors to experiment on the public street. Tesla should have tested this in its closed course by building its own green bollard and then it can crash all it wants but not at the expense of public safety. Https://youtu. Be/zl9rm8d3k34.

At 1:10 pm on Wednesday, November 10, 2021 we were travelling sb on I-5 near longview, wa. The day was clear and dry. We were in lane 2 of a 3-lane stretch of interstate. There were no vehicles in either lane right next to us; a semi-truck was in lane 1 (outside lane) several car lengths in front of us; a passenger car was 1-2 car lengths behind us in the same lane as us (lane 2). No overpasses, trees, or any other discernable distractions were present. We were travelling at 70 mph on cruise control. With no warning, the car braked suddenly in an effort to bring the car to a full stop. Fortunately, the driver directly behind us was paying attention and was able to swerve into lane 3 to avoid rear-ending us. I was able to bring my car into the Tesla location in lynnwood, wa for service on November 12, 2021 to have the issue checked. While in for service, I did some research on the issue and found blogs dating to 2018 about "phantom braking"; I determined this described our situation. When I collected the car, the service tech said they were unable to replicate the issue and therefore, were not able to establish a problem to correct. I inquired if they knew about a phantom braking issue; they indicated that telsa had heard of it and was working on a "fix" but there was no known timeline for the "fix". I have not used the cruise control feature in my car since 11/10/21 and will not because of the significant safety concern. Tesla need to be made to make this safety issue a priority to correct. If musk's team can build a rocket and send it to space, they certainly can correct a cruise control issue.

Repeated violations of autopilot safety systems has forced Tesla to activate in cabin cameras to be used as an additional safety device for driver monitoring. Not all vehicles have in cabin cameras and should be installed for increased safety concerns.

The rear linkages, right front suspension, and upper linkages which is the problem in china has been a problem with my car since day 1.
