2021 TESLA MODEL Y Lane Departure Warning Problems

The car suddenly reduced lane assistance and steering assistance functionality. After calling Tesla they said it is not a software issue. I checked the service mode and it indicated a malfunction in the steering assist motor, which apparently costs $3500 to replace. Online, I have found many complaints about this problem that are not resolved by software updates. In addition, there was a large number used steering assist motors for sale online which indicates a more wide spread problem. This is not normal for cars to have this failure prematurely and is a serious safety hazard. I read online that some had their steering EPAS get locked while driving on the highway and nearly destroyed their Teslas

I was driving along one of the main highways in Orlando, Florida called [XXX], on Wednesday [XXX], in my Model Y Tesla. I was between the exits of [XXX], and [XXX]. I was in the middle lane. There was a software update issued the previous Sunday. The warning came on the display that the lane changing was not valid. At that point the car took over and accelerated. The brakes would not work, until I slammed on it after 3 times, and the car began to decelerate. The air conditioner went off, along with the electrical turn signals. I as able to get off at the [XXX] exit for it is a bit of a "hill" up in Florida, but knew I could coast into a lane hopefully no one would be in. I was able to at least coast into a parking lot, and bump the car into a...

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...

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 [XXX] 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,...

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...

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...

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.

11/29/23: 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. 12/5/23: 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.

B pillar cameras have a known water intrusion issue rendering the camera inoperable and compromising the safety features of the vehicle. Tesla refuses to remedy this known design flaw.

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.

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...

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.

On June 2 around 3:40pm CDT while driving in cruise control on I-43 in Wisconsin around 70mph my car suddenly went into corrective lane assist with warning alerts and steering wheel action. There was no reason this should have happened.

Car was on autopilot full self driving. Truck hit car and vehicle was severely side scrapped. Over 35k in damages. Autopilot did not stop or drive to the side to avoid collision. Autopilot failed Videos can be provided.

All of these incidents occurred with adaptive cruise control engaged, and sometimes with lane keeping engaged. The vehicle frequently brakes, or slows dramatically, when on the freeway and there is no obstacle in the vicinity. Over the last three days I made the drive from Burbank to Anaheim along I-5. Always in the same area, the car would suddenly slow. In two out of the three incidents, the "max speed," which was set to 80, dropped to 45. Simultaneously, the car thought it was in a 55 mph zone (it was a 65 mph zone). In one of the three instances, the max speed was not changed, but the car still slowed dramatically. On the same commute, the car navigation always has me get off on Artesia Blvd, and then get right back on the freeway. The adaptive cruise has a configurable follow distance that the car seems to generally...

While driving along on an interstate highway at night, the frame rate for the display system including speedometer and other vehicle information drastically dropped. This resulted in limited situational awareness of what the car was doing. Updates for lane changing, blind spot detection, and lane departure warnings were delayed/lagged as a result of the reduced frame rate. This did not impact how the vehicle drove, or activation of turn signals, and the lower frame rate did not result in any flickering of the display. A display reset was required while driving at highway speeds to regain full situational awareness.

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...

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...

The Vehicle was in FSD Beta mode and while taking a left turn the car went into the wrong lane and I was hit by another driver in the lane next to my lane. the car gave an alert 1/2 way through the turn so I tried to turn the wheel to avoid it from going into the wrong lane but the car by itself took control and forced itself into the incorrect lane creating an unsafe maneuver putting everyone involved at risk. car is severely damaged on the driver side.

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.

I AM REACHING OUT TO SAY THAT I SAW THE MODEL S AND X RECALL FOR TOUCHSCREEN GLITCHES. I HAVE A MODEL Y 2021 AND I'M EXPERIENCING MANY OF THE SAME CONCERNS AND ISSUES WITH LOSS OF SAFETY FEATURES LIKE BACK UP CAMERA, PROXIMITY CENSORS, LAND CHANGE, AND MORE. THIS TENDS TO HAPPEN WHEN I ENTER THE CAR AND START MOVING. IT WON'T RESOLVE ITSELF TILL I LEAVE THE CAR, WALK AWAY, AND REENTER THE CAR.
