2026 Tesla Model Y: jerking or lurching

Filed Sep 26, 2026 · CO

The vehicle itself will not follow safety lane control. Full self driving was in fact it crosses double white lines and toll roads and will merge into other lanes that has led to unsafe situation excessive ticketing, especially in the [XXX] area. This has happened several times, where it’ll go over the double white line ignore the laws and it will stay in the left lane, causing traffic and disruption. Today it did it several times and jerked into the toll lane when it was a double white line and caused a traffic issue instead of working through it. It signal quickly and then just moved over which was not OK and it was against the rules. Each state has their own set of laws and the cars should be able to adjust each state to follow those laws to ensure safety.

Lane assist and warnings are horrible and can’t be permanently disabled because of your asinine regulations. I have had it try to force me into high way on ramp merge lanes and on unmarked backroads absolutely lose it’s mind and force me over to oncoming traffic because it doesn’t know where the shoulder is. In addition it is over sensitive and likes to blare annoying alarms and jerk my steering wheel when I am not even departing my lane. Thanks for over regulating yet another thing.

Subject: Safety Hazard caused by Emergency Lane Departure Avoidance on [2026 Tesla Model Y] Description: I am writing to report a serious safety issue regarding the Emergency Lane Departure Avoidance (ELDA) feature on my US-spec Tesla. Starting with recent software updates, the vehicle forces the Lane Departure Avoidance setting back to "Assist" upon every single drive cycle, with no option to disable it permanently. This behavior creates an immediate safety hazard, especially in cold climate regions and during winter driving conditions. When attempting to steer around immediate road hazards such as open manholes, deep potholes, or debris, the vehicle's cameras fail to recognize the object in the road. If the driver maneuvers to avoid the hazard without a pre-activated turn signal, the ELDA system aggressively intervenes, jerking the steering wheel back into the path of the danger. On slippery, icy, or wet roads, this unexpected electronic intervention causes a sudden loss of traction, risking a severe crash. Forcing a driver to navigate multiple sub-menus on a touchscreen to change a safety-critical setting before every single drive is dangerous and distracting. In the United States, there is no federal mandate requiring this setting to reset to "Assist" on every drive. I request that the federal safety agency investigate this aggressive software behavior and compel Tesla to restore the option for owners to permanently set Lane Departure Avoidance to "Warning" or "Off".

Lane Departure Aoidane is always enabled for each drive - the car menu states: “Lane Departure Assistance will be reset to Assist on the next drive” - you have to manually go 2 menus and scroll down to the bottom and turn it off every single drive every single transition to Park and drive. The feature is very intolerant. If you swerve around a pothole or a pedestrian or a bicycle, it freaks out and corrects the steering wheel startling the driver and causing a very unsafe situation. I have had several near misses due to this horrible feature. Tesla should design it to be able to be disabled and remember its default state. It’s not a safe feature. It has caused many near accidents and is especially bad in country road driving. The only time he would want such a feature as if the driver is asleep or heavily distracted of which no good driver should be. Tesla has a camera that could detect something like that. This is a safety feature that makes the vehicle significantly less safe. The default for this feature should be disabled for all Teslas. This is a ultra high priority item. It dramatically impacts by driving every day, and I don’t always remember to turn it off until the steering wheel jerks away from me and almost causes an accident!!! This stuff should not be enabled by default!!!

I've noticed periodically when the car is braking at start stop traffic in autopilot mode, the brake is very jerky and I can actually hear the pedal jerking and engaging. I wrote it off at the time in my head as normal operation of the car. I have brake pressure offset codes and brake booster mia codes. Sometimes I've noticed when I brake, randomly the pedal is super stiff and it feels like the car is driving on ice, as if the brakes aren't working or slowing me down at all, but I thought nothing of it at the time. Today on the 14th, I got into an accident at a relatively slow speed that in any other scenario I should have been able to stop. Yet I hit a parked car because as I was braking, I felt the pedal go very very stiff and unresponsive, and I carried the same speed as when I started braking right until impact, it seems as if I didn't slow down one bit. The brakes did not respond as they did mere seconds before and I hit a parked car. I understand teslas may throw codes left and right in service mode that may mean nothing, but I am worried about the brake booster code and wonder if maybe it caused the accident I was involved in. My friends told me they heard about tesla brake issues and that I should look into it and when I went to go check the codes hours later there they were.
