NHTSA Complaint #11719201 — 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.
