2020 Tesla Model Y: lane keeping assist jerks the wheel

Filed Jan 22, 2025 · Driver assistance · WY

After installing Software version 2024.45.25.15 (Full Self Driving software 12.6.2) on my 2020 Tesla Model Y with Autopilot Hardware v3, I experienced unsafe behavior by the autopilot/automatic safety system. On my second drive after the software update, I was unable to engage the autopilot system. Two “Phantom” cars appeared on the full self driving visualization. One “phantom” vehicle was on the left side of the vehicle in my blind spot. A second “phantom” vehicle was shown about 20 feet ahead and 50 feet to the left of my vehicle. (See screen shots). When I attempted to turn left, the automatic lane keep and blind spot warnings took over and attempted to avoid the phantom vehicle. I was able to override the system, but it caused repeated alarms and attempts to move the vehicle back into the lane.

After being parked on a suburban street for about 3 hours, our Tesla Model Y experienced a complete loss of power-steering assist, requiring extreme hand-over-hand effort to turn the wheel and making it dangerous to drive. Warnings of "Steering assist reduced" and "Lane departure avoidance features unavailable" appeared on the display. After a 3-week wait, we finally got the vehicle to Tesla service, who diagnosed the issue and claimed that it was due to "...rodent damage to steering rack harness". They claim to have repaired the damage and the vehicle is again usable. Repair bill was $990. I have the vehicle and it is available for inspection. I cannot verify cause of the issue nor the repairs as they are not visible without a partial disassembly of the vehicle. No parts were returned to me (as I requested), so I must assume that none were actually replaced.

I am writing to formally file a complaint against Tesla, Inc. concerning a significant issue that has arisen following a software update issued to Model Y and Model 3 vehicles in early December. I am a Tesla Model Y owner, and following this update, I have experienced complete failure of critical vehicle systems including cameras, navigation, lane departure warnings, auto braking, forward collision warning, adaptive cruise control, windshield wipers, self-driving features, and car location data. The malfunction of these essential features not only compromises the safety and functionality of the vehicle but also indicates a severe underlying problem with the vehicle's computer system. The cost to replace the affected computer in my vehicle amounted to $2,400. However, upon reviewing discussions on Tesla forums, I have discovered that this is not an isolated incident; numerous other owners are facing similar failures, with some repair bills exceeding $3,000. Given the widespread nature of these issues and their chronological association with the December software update, there appears to be a high correlation between the update and the catastrophic failure of the vehicle computers. The financial burden of these repairs has unjustly fallen on consumers, although it is my belief that Tesla should be held accountable for these failures, given the direct link to their software update. I urge the federal safety agency to investigate this matter thoroughly. It is critical to ascertain whether the December software update directly caused the failures of the vehicle's computer systems and to ensure that Tesla takes appropriate responsibility for the safety and reliability of their vehicles. This includes compensating owners for the costs incurred due to these failures and implementing measures to prevent such incidents in the future. Thank you for your attention to this serious matter.

Failure of all cameras, gps, and lane keeping system. It is available for inspection. It occurred after software update was pushed to the car. Tesla service has seen the vehicle and says that the internal computer has a fault and needs to be replaced. Yet, oddly enough, there are a lot of identical failures reported in Tesla owner forums. Around the same time as my failure in mid-December 2023. No prior indication of computer failure occurred. And the computer is still operational for items not related to the cameras and GPS. Safety concerns: The rear windshield has limited visibility, which is not an issue when the cameras are functioning. The safety notification when changing lanes does not work without the cameras and sensors. The lane keeping and adaptive cruise control do not work without the cameras and sensors. Tesla should investigate if a software update they sent over the air created the problem with cameras and lane keeping assist.

All the cameras in the vehicle are inoperable which causes autopilot not to work. The lane assist feature of the vehicle has stopped working. Driver has to constantly adjust to keep the vehicle from veering into traffic. The navigational system in the vehicle does not work. These safety issues require Tesla's immediate attention as this may lead to a fatal accident.

On a round trip from Albuquerque, NM to Tucson, AZ, we experienced 8-10 instances of phantom braking in our 2020 Tesla Long-Range Model Y. The occurrences happened when the car was in adaptive cruise control and lane keeping assistance. Highway speed was typically 75 MPH, weather was sunny, and roads were clear. Overall, an unnerving experience!

Tesla advertises lane keeping assist, emergency lane departure assist etc. What happens is if you trigger this feature too many times during a drive the software disables this safety feature entirely. There are plenty of disclosures about not relying on the features etc. The issue i feel that warrants intervention from your departments is, how can a manufacture completely disable a safety feature just because a driver actually relied on said safety feature.

Prior to the incident a message appeared in the car indicating that the Lane Departure Avoidance features unavailable - Features may be restored on next drive. TACC was activated on the car. Auto Steer was not activated. The car is equipped with Autopilot only. It was traveling in the furthest left lane. A truck in the center lane attempted to merge into the left lane where our tesla model y was traveling. The car then steered hard left causing the car to be nearly our of control and swerving left and right. We were able to get the car under control, but we nearly were run off the road.

~3 times the car slowed down at ~65mph while on cruise control. Thank goodness no one was closely following us!!! DANGEROUS!!! The car lane assist feature which should warn when us when we're veering to closely to another lane or the edge of the freeway only works intermittently.

The autodrive features malfunctioned. The vehicle is "phantom" braking when a human could easily see there was no reason to brake. This is happening with autopilot (lane keep and adaptive cruise control) engage at freeway speeds (60-70mph). This is occurring randomly on a curve, in the day, at night, in a straight road, cars or no cars nearby. The solution being offered is Tesla service will check the tire pressure and they "remote educated" me by providing links to their autopilot description on their website which states that this can happen. These are extremely dangerous situations and these solutions are not sufficient.

In Tesla’s from model years before 2021, the side “repeater cameras” that are rear facing suffer from a light-leak of the blinker. There are three small holes in the PCB circuit board that allow light from the blinker to leak into the camera at night. Tesla subsequently fixed this problem, first by applying a sticker over the holes in the circuit board, and later by redesigning the part entirely. But this “light leak” problem exists on hundreds of thousands of cars. There are two problems with this: 1) Tesla has now changed their “Autopilot” and “Full Self Driving” software to a Tesla Vision system that ONLY uses cameras for the autopilot features, including lane keeping and lane changes. They no longer use ultrasonic sensors or forward looking radar, even though it is still installed on these cars. This reliance on vision makes it impossible for the Tesla side facing cameras to see when the blinker is turned on. This can result in unpredictable behavior when changing lanes or turning at night with autopilot engaged, including unpredictable or erratic driving where the car abandons a lane change mid course and swerves back into the lane. 2) Even when autopilot is not engaged, the blind spot monitoring in this car consists of a pop up window on the center screen showing the side view camera when the turn signal is engaged. At night, with the blinker on, the driver sees a bright light flashing intermittently in the side view camera. This is very distracting and potentially hazardous to the driver. Tesla has refused to replace the cameras on my car under warranty because they state the cameras are “neither a defect of materials nor workmanship” and are an “expected condition based on the inherent capability of the camera design”.
