Warning problems of the 2021 Tesla Model Y

Lane departure warnings activate briefly when driving straight ahead. Sometimes results in disablement of lane departure assistance feature. Tesla has attempted several repair attempts but issue persists: calibrate radar replace steering rack correct steering angle.

March 31 I received an email from Tesla that I had been selected to participate in a free full self driving (fsd) trial. I have no interest in fsd, and there was no way to opt out of this trial. At some point fsd was downloaded on to my Model Y as part of a regular software update. I was not given the opportunity to accept or refuse this particular feature. While both of these events feel wrong to me, it did not rise to the level of reporting to NHTSA until I realized Tesla had also enabled fsd on my car. In other words they switched my configuration from auto pilot to full self drive, presumably as part of the software update that downloaded the software on to my vehicle. One could argue that because two features on my screen were different I was able to figure out my configuration had changed, and manually change it back. One could also argue that not everyone would sort this out, and the next time they pulled the stalk down to engage cruise control they would unknowingly engage fsd. And that is not ok. I find the timing of all of this ironic given Tesla just settled out of court on a fatality related to their vastly overhyped fsd.

Since installing the update for 23v-838; tc2023-657 compliance, you guys have absolutely ruined autopilot. Your regulatory overreach has resulted in my task workload increasing while using any adas systems Tesla supplies, and multiple times I have reached task saturation from the number of nags, alerts, and prompts that have appeared since applying the 23v-838; tc2023-657 update. In some cases I have engaged autopilot, been nagged, wiggled the wheel which disengaged, re-engaged, been nagged, wiggled the wheel which disengaged, re-engaged, 3 times in a row. I have benchmarked almost every other adas system on the market and you chucklefucks have somehow regulated Tesla auto pilot into a place where it has literally the most frequent nags, alerts, prompts, and annoyances of anything on the market. Ask yourselves whether you honestly think nags that audibly prompt and distract the driver for merely glancing at the autopilot set speed, briefly adjusting the map, or even daring to adjust vent position are really a wise tradeoff, or just something you cooked up because you have an axe to grind. Here's another one - as petty bureaucrats, would you rather have autopilot or fsd on the road, or a hypothetically drunk driver?.

Tesla autopilot lost control in rainy weather, swerved off the road on freeway at 80mph, swung back in the leftmost lane and then to shoulder, risking lives of driver and all passengers including 2 children. Impact resulted in broken wheel rims and bursted tires. This could have been fatal accident if there are other cars on the road at the time of incident. There were absolutely no warning on the screen and near zero time to react with vehicle wheels turning sharp left at 80mph. Footage though immediately visible on dashcam has disappeared from usb drive. Requested vehicle logs from Tesla but that too has gap in coverage exactly during time of accident. Tesla service center has not responded to request to get system log at the time of accident. Missing logs and camera footage exactly at the time of incident is suspiciously missing. Footage and logs are available for next day as well as several weeks and months in the past.

Subject: safety concerns regarding recent Model Y autopilot update to whom it may concern at the national highway traffic safety administration (NHTSA), I am writing to urgently express my concerns about the latest software update for the Tesla Model Y’s autopilot system, which, in my view, significantly compromises safety. As a model 3 owner for over one year, I have generally found the vehicle and its features to be reliable and safe. However, the recent update has introduced an overly stringent hands-on-wheel detection mechanism that is not only inconvenient but also potentially hazardous. The new update requires frequent and often forceful interaction with the steering wheel to assure the system of driver presence. This change is drastically different from my previous experience, where I received only one hands-on-wheel violation in two years. The current sensitivity of the system disrupts the smooth operation of the autopilot, leading to frequent and abrupt disengagements. I have found myself struggling to maintain the system’s activation, inadvertently causing the vehicle to exit autopilot mode multiple times. This issue goes beyond mere inconvenience; it actively detracts from driving safety. The need for constant and sometimes aggressive adjustments to satisfy the system’s requirements is distracting and can lead to erratic vehicle behavior. The irony is stark: a system designed to enhance driving safety and ease is now a source of potential danger and stress. The unpredictability and over-sensitivity of the updated system could lead to dangerous situations, especially on highways or in heavy traffic, where sudden disengagement of the autopilot can be particularly risky. As a driver, I now find myself more focused on keeping the autopilot engaged than on the actual driving conditions and surroundings, which is surely contrary to the feature’s intended purpose. Thank you for your prompt attention to this serious safety concern. Sincerely, paul ramsingh.

The power steering stopped working. "error ui_a020: steering assist reduced," and "error app_w264: lane departure avoidance features unavailable" appeared on the screen afterwards. I was driving home when suddenly I was unable to turn the steering wheel more than a quarter turn (even with all my weight and strength). I tried resetting my vehicle and the issue persisted. I also tried getting out of the vehicle, locking it and let it sit but the issue persisted when I got back in. Luckily, I had just entered my neighborhood and managed to get it parked in my driveway. After a couple hours of the vehicle sitting in my driveway, the issue stopped. I took the vehicle to the Tesla service center where it was inspected, they informed me this is a known issue with current firmware and an unknown future update will fix the issue.

11/29/vehicle begins to flash warning alerts (e. G. , traction control disabled, lane departure warning unavailable), then power steering stopped working, and brakes pulsed violently when used (almost like abs was active). Software update was available shortly thereafter, assumed this would remedy the situation. 12/5/same problems recur (loss of power steering, odd braking behavior, vehicle alerts). Vehicle was towed to Tesla for service. Tesla was able to id the alerts in the vehicle history but could not identify the root cause. Took the vehicle one extended test drives, but was unable to cause the problems to recur. Tesla is unable to identify any further actions to prevent recurrence.

Several instances of emergency braking applied without warning or obvious need during multiple driving sessions. This results in an unexpected rapid vehicle deceleration. Fortunately no other vehicle was following close enough to represent an imminent safety hazard though it is easily plausible this could happen. Typically the issue occurs when traveling uphill or around a bend and encountering traffic in an oncoming lane, structures (bridges) or dark shadows. The unexpected emergency braking has also happened when adaptive cruise control or autopilot is engaged while overtaking large vehicles on the left (tractor trailers in the right lane). I have also noticed several erroneous lane departure warnings despite turning off these notifications on the dashboard. They are more a nuisance than safety hazard so far but would like to completely silence them entirely. These issues have yet to be reproduced or inspected by the dealer, police, insurance or other investigator. No warning lamps or indicators were active at the time the braking or lane departure warnings were observed.

Recently, I had a long distance trip and and Tesla Model Y braked the vehicle at highway speed when it was on advanced cruise control 3 or 4 times with obvious reasons. I had to push the acceralator pedal to speed up in order to avoid rear ended collision in a bumper to bumper traffic.

Currently and noticing other reporting the inaccurate location of the gps in the car. At times the car gpe will drift into areas not associated with the cars correct location. If the car is in adaptive cruse or Teslas autopilot the car will maintain the posted speed limit for that gps location or a delta of the users defined (+ - 10 or 15 mph). This cause a car to abruptly reduce the speed if not within the posted speed limit for that area. For example a car in autopilot or adaptive cruse going 70mph on the highway, the gps will start drifting into areas outside of you location and abruptly reduce the speed to assumed location. This is even more troublesome if autopilot is engaged where the car will try to change lanes as directed by the gps.

The vehicle driver assist system frequently has phantom braking in situations it should not be, especially when there are vehicles behind putting us at risk for a collision due to unexpected braking behavior of the car. This happens especially in setting of 2 lane roads with oncoming traffic, and guaranteed with a truck in the vicinity. On major highways it is less so, but does still happen occasionally. On local roads even if straight and no obstruction the automatic braking without notice occurs when least expecting. Also the lane departure system disables automatically for the remainder of a drive if you veer off a lane even once and didn't take the corrective action the vehicle thinks should have happened. That's not how a safety feature should work. . . It should remain on regardless. As much as I do enjoy this car, these quality issues definitely make you second guess and keep a closer eye on how you drive to avoid accidents if the system decides to not work as advertised.

Vehicle constantly experience phantom braking. Will randomly brake for shadows, vehicles in the opposing lane, and when it feels like it. Chance for rear collision is higher due to autopilot.

On Monday November 22 at around 6:15 pm cst, I was driving my Model Y and had Tesla's full self driving beta software engaged. A right banked curve on a two lane road in a rural area came up with a vehicle coming around the curve the opposite direction. The Model Y slowed slightly and began making the turn properly and without cause for concern. Suddenly, about 40% of the way through the turn, the Model Y straightened the wheel and crossed over the center line into the direct path of the oncoming vehicle. I reacted as quickly as I could, trying to pull the vehicle back into the lane. I really did not have a lot of time to react, so chose to override fsd by turning the steering wheel since my hands were already on the wheel and I felt this would be the fastest way to avoid a front overlap collision with the oncoming vehicle. When I attempted to pull the vehicle back into my lane, I lost control and skidded off into a ditch and through the woods, causing significant damage to the vehicle. I was able to retrieve the dashcam footage of this incident and it is attached here. I did analyze the footage myself briefly. You can see the vehicle leave the lane, and within about 10 frames, I had already begun pulling back into the lane before losing control and skidding off the road. Since this video is recorded at about 36 fps, this would mean I reacted within 360ms of the lane departure. I understand it is my responsibility to pay attention and maintain control of the vehicle, which I agreed to when I enrolled in fsd beta. I was paying attention, but human reaction does not get much faster than this and I am not sure how I could have otherwise avoided this incident. I am thankful this was the outcome rather than a front overlap collision with the oncoming vehicle, which would have likely resulted in bodily injury. Tesla has confirmed that fsd beta was engaged, per the attached correspondence, but insists that this incident and the resulting accident are my responsibility.

Vehicle made a sudden right turn when it was on auto pilot and because of that there are minor cosmetic damages to wheel and tire. Manufacturer doesn't accept any fault when it was humanly impossible to control the vehicle because of sudden turn.
