Warning problems of the 2026 Tesla Model Y

I am submitting this complaint regarding a newly leased 2026 Tesla Model Y premium rwd, which I took delivery of on February 6, 2026 from Tesla watertown, MA. I am a returning Tesla customer and entered this lease after test driving the same model on January 24, which did not exhibit any issues. Immediately upon driving the vehicle off the lot (approximately 12 miles), I noticed a persistent rattling noise from the front suspension area. The noise occurs over normal road conditions and has been present since delivery, significantly affecting the quality and value of the vehicle. On February 9, Tesla watertown evaluated the vehicle and later replaced both front upper control arm (fuca) mounts. On February 10, before repairs were completed, multiple safety systems suddenly disabled while driving, including regenerative braking behavior, traction and stability control, lane safety features, and automatic emergency braking, creating a dangerous situation. I returned the vehicle immediately and was provided a loaner. I picked up the vehicle on February 13 and was told the suspension issue was resolved, but the noise remained. I then sought a second opinion at Tesla peabody, where a master technician conducted a ride-along and confirmed the condition. He verified that the latest fuca parts had been installed and the front structural “pencil braces” had been removed per Tesla guidance. I was informed the vehicle falls into a known noise category affecting 2026 rwd Model Y vehicles and that there is currently no repair or engineering solution available. This defect has existed since delivery and remains unresolved after multiple service visits and component replacements. I have contacted Tesla regional leadership and customer support multiple times without response.

The lane departure warning and lane assistance features generate numerous warning that are false. The false alarms are shocking and distracting creating alarm fatigue. Alarm fatigue is dangerous. The lane assistance feature is much too aggressive. Tesla does not allow for these features to default to off. They are mandated for every start up and have to manually turned off every drive. Tesla told me, "they are working as intended. " other car makers allow you the choice of on or off. I have to go through multiple steps every single time I drive the car to remove the alarm fatigue and false steering interventions. Both are hazardous. I actually get an alarm that says "take the wheel" while my hands are on the wheel. I get numerous fantom alarms. Please make Tesla release a sw update that allows people to choose their own driving defaults. Thanks.

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.
