How the 2025 compares with nearby years
Against the 2020 Model Y: The wiper blade lengths is the same in both manuals.
The 2025 Model Y belongs to the 1st gen, which began with the 2020 model year (2025 'Juniper' refresh (N.A. from Mar 2025): full-width front light bar and light-bar taillights, new nose; Standard trim (Oct 2025) drops front light bar); generation dates. Parts often carry over within a generation, but the manual for your exact model year is the one to trust.
What the manual does not print
The 2025 Tesla Model Y owner's manual does not list bulbs, filters and oil sizes; many lamps on this model are LED assemblies that are replaced as a unit by a dealer.
Buying the parts for a 2025 Model Y
- Wipers: ask for a 26-inch driver blade and a 20-inch passenger blade. The manual's 650 mm is 25.6 inches exactly; blade boxes round to the 25 mm trade step. Check that the new blade's connector matches the arm on the Model Y.
- Battery: the manual prints Lithium-ion low-voltage battery, 6.9 Ah (5-seater) / 12 Ah (6-seater). Match the cold cranking amps on the old label or higher, and keep the terminals on the same sides.
Check it on your car
