First-Generation YD1 Sunroof Design and Glass Specifications
The first-generation Acura MDX (chassis code YD1, model years 2001 to 2006) came standard across both Base and Touring trims with an electric tilt-and-slide moonroof assembly. Unlike bonded stationary auto glass panels, this sunroof is an integrated modular unit: a factory-tinted, heat-absorbing tempered glass panel bonded directly to an underlying metal support frame and wrapped with an integrated perimeter rubber seal. OEM assemblies carried part numbers 70200-S3V-A01 and later superseded to 70200-S3V-A11. In the aftermarket industry, the replacement glass unit is cataloged under NAGS number SR10292.
When this glass shatters from impact, debris on the highway, or severe stress, it fractures into blunt tempered pieces. While the interior sliding sunshade can catch a portion of the debris, thousands of fragments regularly drop into the sunroof cassette, mechanism tracks, and drain troughs. Replacement requires handling the glass and the underlying mechanical assembly together.

Mechanical Fastening, Track Clearing, and Drain Service
Replacing the glass on the YD1 MDX does not require pulling down the entire molded headliner if the track sliders remain intact. Access begins by unsnapping the flexible side trim skirts that run along the left and right interior edges of the glass frame. This reveals four Torx machine screws (two on each side) connecting the glass bracket to the mechanical drive shoes. Once these fasteners are removed, the glass panel lifts upward and out through the roof opening.
The critical phase is decontaminating the sunroof frame assembly. Broken fragments gather inside the guide rails, jam the worm-drive cable spirals, and clog the four drain hose spouts positioned at each corner of the cassette. If these corner spouts remain blocked, rainwater bypasses the seal, overflows the inner tray, and pools behind the A-pillars or drenches the floor carpets. I clear the tracks completely, snake the front and rear drain channels to ensure rapid water evacuation, and clean old contaminated grease off the guide tracks before sliding the replacement glass into position.
I provide mobile service only: I come to your home or workplace anywhere in Toronto and the GTA. Once booked, I can be on-site in about an hour to replace the damaged panel on your driveway or parking space.
Panel Height Alignment and Water Deflection
A frequent mistake on first-generation MDX sunroof replacements is tightening the side Torx screws without establishing correct panel height relative to the roof skin. The roof sheet metal slopes slightly toward the rear, and proper wind-deflection geometry depends on exact spacing:
- The front edge of the sunroof glass must rest roughly 1.0 to 1.5 millimetres below the leading edge of the vehicle roof sheet metal to avoid highway air buffeting.
- The rear trailing edge must sit flush or roughly 1.0 millimetre above the vehicle roofline to shed wind and standing rainwater cleanly toward the rear hatch channels.
- The perimeter rubber seal must compress uniformly against the sheet metal flange along all four sides to prevent excessive air rush and whistle at cruising speeds.
I source aftermarket glass only, using panels manufactured by trusted suppliers such as Pilkington, FYG, XYG, and PGW to guarantee correct curvature and edge trim tolerance. You receive a lifetime warranty on my workmanship alongside a one-year warranty on the glass itself. Once the bracket screws are torqued down, the motor limits are synchronized and the panel undergoes full operational cycling—verifying seamless tilt, slide, auto-stop, and water-tight sealing across the cassette.
