Warning problems of the 2023 Tesla Model Y

-as a regular driver in the DC area, I have repeatedly experienced the lane departure avoidance system disabling itself mid-drive. This is particularly troubling in city driving conditions marked by unpredictable traffic, unclear lane markings, and frequent distractions—scenarios where these safety features are most essential. Lane departure avoidance helps prevent accidents by alerting drivers or gently correcting steering if the vehicle unintentionally drifts out of its lane. -I don't know if there was a specific concern about the safety of others, but it may have. -unknown -not needed -no - just happened.

There is a steering malfunction, with my Tesla Model Y it completely locks up and the steering is disabled. The steering doesn’t move at all the following warning and codes appeared on the dashboard. Di a223 traction control disabled drive with caution dl a222 stability control disabled drive with caution gtw_w074 steering assist reduced steering may require increased effort ul_a020 steering assist reduced steering may require increased effort. Now this is the second time it has happened within few months. It was taken to the dealership with the same complaint this was their diagnoses concern: customer states: feature availability & settings - steering is disabled, park assist disabled , stability control disabled, traction control disabled, vehicle hold disabled repair notes: confirmed customer concern.

There is a serious and unsafe issue with this car. A potential disaster waiting to happen.

When on autopilot, the car engages in "ghost braking" for no valid reason. This has happened a couple of time. The last incidence happened today, 02/16/2024, at about 10:38 a. M. While on a freeway. I was lucky that there was no cars immediately following me, otherwise a chain accident with pile up would had happened. This was a very risky and scary incident.

I was driving in the left lane of the highway. Just up ahead I saw something sitting on the guardrail to my left which was jutting into my lane, right about eye level. It looked like a long wood 2x4. I swerved to my right to avoid hitting the piece (scared it would shatter my windshield) and the steer correct safety feature (probably wrong term) quickly threw me back to the left and into the guardrail. I turned my steering wheel to the right to get away from the guardrail and it threw me back into the guardrail. It did this a few times. I didn’t understand what was going on. It felt like I had no control over the car. It just kept slamming back into the guardrail. I finally took my foot off the gas and it slowed down and stopped throwing me around. Luckily, there was no one next to me and no one else in the car with me. No one got hurt. If it wasn’t for that “safety” feature, my car wouldn’t have been damaged. I did call the police to let them know about the wood piece that was sitting on the guardrail so hopefully it gets removed and no one gets hurt.

I purchased my Tesla Model Y in January of this year. Tesla removed all ultrasonic sensors from the car, and is instead relying only on "Tesla vision". However, 9 months later and I still don't have several safety features Tesla promises. Rear cross traffic warning and blind spot warning don't work at all. The lane departure warning only works over the solid outside line, and doesn't warn at all when crossing between lanes (ie a dotted line). In addition, the adaptive cruise control randomly brakes dramatically for no apparent reason. This is extremely dangerous, as drivers behind don't expect you to quickly decelerate in the middle of the highway for no reason.

While driving in the city on under construction road, the car started showing notifications that the steering power will be reduced. 30 sec. Later the steering wheel froze and the car was drivable only forward and backwards. This safety system malfunction put me and my family at risk while in active driving mode, luckily there was no much traffic and I was able to reset the car in order to be able to drive it again. Bumpy road shouldn’t cause the system to malfunction and limit the driving capability, especially not while active driving. I wasnt using any cruise control or auto pilot features.

Vehicle was parked on the street. Put car in drive, loud noise came from steering column, and warning message shows steering assist reduced and lane departure avoidance features unavailable and at that point the car had no power steering. Car was reset 4 times. Every time the vehicle was reset, loud noise came from steering column, both warning messages appeared, and no power steering. On 4th reset, power steering came back, but both warning messages still appeared.

The steering wheel on my 2023 Tesla Model Y, brand new with only 800 miles on it, kept on locking up out of nowhere, in the middle of the drive, and even on the highway, posing a major safety concern for me and everyone driving around me. My safety was put at risk since I could not steer my vehicle off the road and into a safe area, posing a risk-prone of a severe accident through rear-ending. The problem was notified to Tesla service, which responded super late to this incident where I had to call them and wait on hold for 1 hour to speak to a representative who then followed up and told me to drive it to the closest service center, which I declined since the steering wheel locking up at random is a major safety. Tesla stated that I would need a new steering rack installed on my brand new 2023 Model Y. I don't understand how these vehicles are inspected and pass quality control on such a major issue. This issue is not just about a broken part but a life or death situation and should be dealt which severely. I got multiple lights and messages when the failure occurred while driving, with steering assist required being the last notification which I have attached in the pictures.

Summary: loss of power steering/inability to steer the vehicle occurred twice (7/16/23 & 7/29/23). Issue appears consistent with investigation pe 23-014. Other functionality was also lost on each occurrence. Details: 7/16/23 - driver entered the car and immediately received several alerts including steering assist reduced, stability controlled disabled, traction control disabled, lane departure avoidance features unavailable, and vehicle hold disabled. Steering wheel could not be turned and regenerative braking was not functioning. A video of the issue was created and is available upon request as it could not be loaded in its current format. Tesla was contacted on 7/17/23. They stated that a firmware update failed on the evening of 7/15/23. The vehicle was towed to service center and firmware was updated. The invoice from the service center as also attached. 7/29/23 - driver entered the car and immediately received several alerts including steering assist reduced and lane departure avoidance features unavailable. The steering wheel could not be turned, but only with extreme force. There was no firmware update at this time. I was able to drive the car 3 miles to my home at very slow speeds. 2 videos of the issue were created and are available upon request as they could not be loaded in their current format. Tesla was contacted on 7/30/23. The vehicle was towed to service center where they determined that the steering rack needs to be replaced. The vehicle remains at the service center for repair. Background: car was just received on 6/30/2023. I have had other issues as well. Upon receipt, the electronic seat mechanism was not working and my cameras do not appear to be measuring distances properly.

The lane departure avoidance system fails to trigger consistently when crossing over the lane markings. In the rare instances when the system does trigger, neither of the 2 available modes: steering correction or alert, give a significant enough input to be made aware or correct the problem. Another issue is when the lane departure avoidance system is triggered for an extended amount of time (~10s-ish or more when driving near the lane markings), the system is completely disabled for the powercycle of the car. Thus, this system is not just unreliable and useless when it does work, but also completely disabled after driving near the edge of the road for a little while without any way to re-enable it. Tesla service responded that they won't fix or correct this problem. There are no system failure notices displayed by the car. Vehicle has not been inspect by manufacturer or other.

When I purchased this vehicle, I was told that all adas features would be available once the cameras calibrated (approximately 50 miles). After 100 miles my wife bumped into a wall in our garage. I opened a ticket and Tesla said the adas features are unavailable until a software update is sent. The sales person who I spoke to were not aware of this. This is extremely dangerous. Drivers are reliant on warnings from features like this and to have the features off without a warning could get someone run over.
