Reilauto Tesla Model Y Left Side Mirror Lower Cover — ABS 1:1 OEM Fit, Snap-In Replacement

Reilauto's left lower side mirror cover is a direct-fit ABS replacement part designed to restore the bottom cap of the Tesla Model Y's triangular mirror base.

This replacement lower cap snaps into the original mirror housing on Tesla Model Y models from 2018 through 2025. Built to match the factory part shape and mounting points, the cover seals the underside of the mirror base to prevent moisture entry, protect internal components, and provide a tidy finished appearance. It's an OEM-style, 1:1 molded part made from durable ABS that installs quickly with minimal tools.

How will this cover improve my Tesla Model Y's mirror durability?

Replacing a missing or cracked lower mirror cap closes the exposed gap at the triangle base, limiting water, dirt, and road debris from reaching delicate mirror internals. The ABS construction resists everyday impacts and UV exposure better than brittle plastics, reducing the chance of repeated damage.

• Seals the mirror lower base against rain and splashback
• Shields internal mechanisms from grit and corrosion
• Durable ABS resists cracking from minor impacts and aging

Is the Reilauto piece easy to fit without professional help?

Yes — this part is made to the same dimensions and clip positions as the original Tesla cap for a straightforward replacement. The package includes a short instruction manual and the swap typically takes under five minutes, using common hand tools or only manual pressure to snap into place.

Will the replacement match my car’s appearance and performance?

• Paintable ABS surface for color matching
• Clips and tabs designed for stable, rattle-free seating
