A firmware diagnosis feature is being introduced on Model 3 and Model Y vehicles that monitors wheel alignment over time. This feature detects changes in wheel alignment that may be related to incorrect tire pressures, degraded ball joints, bushings or damaged suspension links. If the feature determines that an inspection at a Tesla Service Center is required, a customer-facing alert will appear on the touchscreen.

On some Model Y vehicles, the rear view mirror upper camera cover is not sufficiently transparent, which may prevent infrared light from traveling through the cover, resulting in increased vehicle occupancy warnings in low-light conditions. This has no effect on vehicle operation or Autopilot features. Inspect the vehicle for symptoms related to the condition. If symptoms are present, replace the rear view mirror upper camera cover.

On some Model Y vehicles built before February 28, 2026, the design of the HVAC inlet duct may lead to water ingress into the air filter and/or vehicle interior. If the vehicle is brought into Service for cabin air filter replacement due to a musty or moldy smell from the HVAC system, water dripping from the vents or water pooling into the RH footwell carpet, inspect the vehicle for symptoms related to the condition. If symptoms are present, replace the HVAC inlet duct with an updated part or rework the existing HVAC duct, and replace the cabin air filters.
