2026 TESLA MODEL Y Lane Departure Problems

Approximately one month after purchasing a new vehicle, the steering system suddenly failed without any warning. While the car was parked at home and started normally, the steering wheel became extremely heavy, hot, and then completely locked. The vehicle could not be steered at all and became entirely non-drivable. Multiple warning messages appeared, including warnings related to reduced steering assist effectiveness and lane departure avoidance being unavailable. This occurred at approximately 1,000 miles. The failure happened suddenly with no prior symptoms. This defect created a serious safety risk. If this had occurred while driving, it could have resulted in loss of vehicle control and a potential crash. The vehicle was not drivable and had to be towed to a Tesla service center. The issue has been reported to Tesla and is currently under inspection. The exact cause of the failure is UNKNOWN at this time. A sudden and complete loss of steering control on a nearly new vehicle is extremely dangerous and indicates a potential defect in the steering system or related electrical components.

My car installed update v12 (2025.38.8.7) last night. This morning I was driving to work using autopilot when alarms sounded, the hazard lights turned on, and the screen flashed a warning that I had to take over immediately. The message included a note that autopilot had failed due to a "systems error." The navigation and visualization screen froze, went blank, and took 10 minutes to come back on. I asked Tesla to roll back the update and they have told me that they cannot do that. I came very close to crashing into a concrete guard rail as the car was going around a turn when the system failed.

While driving in rain at night, the vehicle’s automated driving system attempted to make a turn at an intersection near active train tracks. Instead of remaining on the roadway, the system steered the vehicle directly onto the train tracks, where the vehicle became stuck between the tracks and the paved road surface. All four tires were damaged, and the vehicle could not return to the travel lane under its own control. If a train had been approaching, this situation could have resulted in a severe or fatal collision. I had to manually reverse the vehicle a significant distance to return to the roadway. The malfunction appeared to result from the automated driving system misidentifying the roadway under rain and low-visibility conditions. This suggests a recurring risk for any vehicle using the system at this location in similar conditions. The safety issue has not yet been inspected or confirmed by the manufacturer. No warning lights or alerts were displayed prior to the incident. The affected components and system are available for inspection upon request. I also have dash-cam video of the incident documenting the event.

My Tesla Model Y was in Full Self Driving Mode when it turned into a garbage truck, leading to a total loss to my car. There were no warnings from the Tesla system that could have helped me prevent the crash. Thankfully, no one was hurt, but my car is not longer usable.

What component or system failed or malfunctioned, and is it available for inspection upon request? The Full Self-Driving (FSD) system malfunctioned. While traveling northbound with the flow of traffic in the middle lane of a surface street, the vehicle initiated a sudden right turn onto a freeway on-ramp at excessive speed and without adequate steering input. This resulted in the vehicle colliding with the left-side barrier. The vehicle is currently in the custody of State Farm Insurance and can be made available for inspection upon request. Dashcam footage of the incident has been preserved. How was your safety or the safety of others put at risk? The unexpected maneuver caused the vehicle to lose control and strike the barrier, placing both the driver and other motorists at risk. The driver had no time to react to this unexpected action. The driver sustained a whiplash injury along with left shoulder and right chest pain. If another vehicle had been present in the adjacent lane, a collision could have occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? No. The issue has not been reproduced or confirmed by a dealer or service center at this time. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by State Farm Insurance for collision damage. A request has been made to Tesla to preserve and provide all electronic data logs, event data, and over-the-air communications. No law enforcement or EMS responded at the scene. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamps, messages, or alerts were displayed prior to or during the incident. The maneuver occurred suddenly and without any indication that corrective driver action was needed.

Yesterday on October 1st I was driving car recently last few days my car usually go more right side but I thought this may be due to keep in lane car feature or something so I didn’t bother much but yesterday when I was driving at around 11:13 am I didn’t know I reciived notifications in car about 1.automatic vehicle hold disabled 2.tracking control disabled 3. Stability control disabled 4.break pedal regenerative breaking unavailable 5.lane departure avoidance feature unavailable 6. Automatic emergency breaking unavailable And I see from y car pe drive vidio recording in 11:14 minute one my car hit curb and it damages my both side wheel and tire so badly damaged and broke like out of both pieces came off but didn’t flat my tire and when this happens I was trying it break but it didn’t break instead in lost all function so it was kind going fast and lost all control and with lot of work my car wind on side and then completely turn to other side this all happened in few seconds and was very scary I wasn’t far from tesla service centre and I have wheel protection and tire protection plan so I took straight to tesla service centre and I ask them about using my that plan and after some time they said based on damage and they check video they said this is collision and at that time I wasn’t aware what to do and this and that and I wasn’t fighting and I didn’t know about video or notifications all untill they show me and ask me to file insurence claim for collision and luckily I took picture of notification picture in car at that time and then I end up following insurence claim process in hour of something it took me and then went in car to take tesla flash drive and my stuff I saw they put vehicle in service mode and all notifications were cleared and I even tell them luckily there wasn’t car near by or highways and no one on street and it avoided big incident but all this failure due to impact or this impact due to failure I want investigation because I suspect

Update to ODI 11678614. This problem applies to non-FSD (Full Self Driving) Tesla Model Y cars. Tesla's manual describes Autopilot as Traffic Aware Cruise Control - it's the first step on non-FSD cars. The second step on non-FSD cars, Autosteer, is active lane keeping. In older Ys, the first stalk pull engages autopilot, second pull engages autosteer. 2026 Juniper doesn't have a stalk - a single scroll wheel press engages both. I read the 300 page Juniper 2026 Model Y manual before driving it for the first time. On page 108, it lists 7 things that will cause autopilot to disengage. I presumed that comprehensive list was complete. unable to attach. Having *autopilot* disengage when turning the wheel in *autosteer* is not listed. During my 59K miles on my 2021 Model Y, I used autosteer for at least 20K miles. Turning the wheel in autosteer did *not* disengage autopilot. In my first emergency situation in the 2026 Juniper Model Y, turning the wheel *did* disengage autopilot, and the regen properly kicked in for the disengagement. This action came very close to causing a serious accident. My objections are 1) the action of *autopilot* (disengage / remain engaged) when the wheel is turned in *autosteer* is not documented, and 2) it's different between the old and new Ys using the same current software. I understand there were problems with autopilot remaining engaged, and perhaps the change was a good idea; that's an entirely different discussion. Make the action consistent and document it and I'm happy. Summary: In heavy traffic, while on autopilot / autosteer (cruise + active lane keeping), the car beside me suddenly tried to pull into my lane. I made an emergency lane change by turning the wheel, but the cruise also disengaged, (contrary to operation in the prior model) and went to maxiumum regen braking, causing the car behind me in the new lane to nearly rear-end me. Punching the accelerator during the surprising braking avoided the collision.

I've driven my old 2021 Tesla Model Y for 4 years / 59K miles. Four days ago, I got a new 2026 Tesla Model Y. The new Y has made a change to the interaction of the cruise control and automatic lane keeping. In the old one, first cruise was enabled, then lane keeping. If you disengaged lane keeping by overriding the steering wheel, cruise control was maintained. In the new Y, a single selection enables both cruise and lane keeping. The safety issue is that overriding lane keeping by turning the steering wheel disengages both features at once - the old method kept cruise control enabled. I was driving in heavy traffic today on a 6 lane interstate with cruise and lane keeping enabled. The car next to me abruptly swerved into my lane, causing me to make an emergency lane change to avoid a collision. When I overrode the lane keeping to avoid the other car by turning the steering wheel, my cruise control also disengaged (unlike the old system), which caused maximum regenerative braking to kick in, abruptly slowing me in the new lane. I had to punch the accelerator to avoid being rear-ended in the new lane. This change in lane-keeping / cruise control applies to all new 2025/2026 Model Ys - the "Juniper" model update. This change, according to Reddit and Facebook forums, seems to be universally hated and many other drivers have raised the same safety concerns. I agree with them, but didn't make a report until now because I had not yet experienced an issue where this almost contributed to a high-speed crash. thank you.

Incident Date: July 12, 2025 Approximate Time: 1:30 PM Vehicle: 2026 Tesla Model Y Location: I‑75 South express lane toward I‑285 East, Marietta, GA Event Summary: While Autopilot was engaged, the vehicle was entering the exit ramp to I‑285 East when it abruptly veered left into the I‑285 West entrance ramp, against traffic, crashing through two “no entry” security gates. I was able to safely bring the vehicle to a stop before entering oncoming traffic. Crash Details: • The vehicle struck two barrier gates. • Impact shattered the windshield, spraying glass across the cabin. • Both my son and I sustained small cuts from glass shards. • Vehicle was rendered undrivable and had to be towed by authorities to a secure facility.

I was driving with FSD on [XXX] and had to intervene to take control when a bumper showed up on the road. When FSD was driving in standard mode, it was driving at 72 miles/ hr and was too close to the prior car. When the prior car quickly dodged the bumper my car was already too close to the bumper and needed to make a quick turn. The car almost rolled over. Dashcam video: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I owned the vehicle less than a month, using full supervised drive, FSD. Today 6/22/2025 1:45 PM almost had an accident. The vehicle was in the right made a left turn crossing a yellow line, then made a turn in a white line, in front of the vehicle behind me. I took control of the vehicle to proceed in the correct lane. On another occasion it made a right turn, corrected itself to the left lane as it should have done. I am hearing impaired, focus on the road, cannot look at the screen monitor while driving. The vehicle stopped, advised me FSD was inoperable, had to manual drive to my destination. There is no warning, alerts for the hearing impaired. Other issues driving in the wrong lane, then at the last minute changes to the correct lane, I am certain cutting off drivers. UNKNOWN
