Assist problems of the 2026 Tesla Model Y

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 * disengage autopilot. In my first emergency situation in the 2026 juniper Model Y, turning the wheel * 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.

I was driving with fsd on highway 520 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: https://drive. Google.

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.
