2004-2006 Scion xA Roof & Sunroof Guide: Fixing Leaks, Rust, and Replacement
This definitive guide covers the critical differences between sunroof and non-sunroof models, how to diagnose common water leaks, and what to look for when buying a used roof assembly.
- There are two distinct roof types: a solid panel and a sunroof assembly. They are not interchangeable, so verify your car's setup before buying parts.
- Replacing the entire roof panel is a major structural job requiring professional welding and is not feasible for DIY. Labor costs can exceed the car's value.
- Sunroof water leaks are almost always caused by clogged drain tubes, which is a simple maintenance fix you can do at home with a flexible wire.
- When buying a used roof, inspect it carefully for rust (especially under trim and around openings), signs of previous body filler, and brittle sunroof seals.
Two Roofs, Zero Interchangeability: Sunroof vs. Non-Sunroof
Before diagnosing issues or buying a replacement, you must identify which roof your 2004-2006 Scion xA has. The two versions are fundamentally different and their parts are not interchangeable.
- Solid Roof (Non-Sunroof): This is a single, structural steel panel that is welded to the car's body. It has no openings. The corresponding OEM part number for this panel is 63111-52350.
- Sunroof / Moonroof Assembly: This version features a large cutout in the structural roof panel to accommodate a sliding glass panel and its motorized frame, known as a cassette. This assembly includes the glass, seals, motor, and a drainage system to manage water.
Warning: You cannot install a factory sunroof assembly into a car that originally had a solid roof without extreme, costly, and unsafe structural modification. Always purchase a replacement roof that matches your vehicle's original configuration.
Symptoms of Roof Assembly Failure
Problems with the Scion xA roof can range from minor annoyances to serious issues that compromise the vehicle's interior and safety.
- Water Leaks Inside the Cabin: The most common symptom. Water may drip from the headliner near the sunroof, from the overhead console, or run down the interior pillars (A-pillars by the windshield or B-pillars by the seatbelts).
- Wind Noise: A damaged or misaligned sunroof seal can create excessive wind noise at highway speeds.
- Visible Rust: Bubbling paint or visible corrosion on the roof panel, especially around the windshield edges, in the roof channels under the black trim strips, or around the sunroof opening, is a serious concern.
- Malfunctioning Sunroof: The sunroof may get stuck, operate slowly, make grinding noises, or fail to open or close at all.
- Sagging or Stained Headliner: This is a clear sign of a persistent water leak, even if you haven't seen active dripping.
- Sunroof Glass Separation: In some cases, the adhesive holding the sunroof glass to its metal frame can fail. This allows water to get under the glass and bypass the drainage system, leading to leaks directly into the cabin.
Known Issues, TSBs, and Recalls
Common Problem: Clogged Sunroof Drains
Nearly all sunroof leaks on the Scion xA are caused by clogged drain tubes. The sunroof assembly is not designed to be perfectly waterproof; instead, it features a tray or gutter system that catches water and directs it to four drain tubes located at the corners of the sunroof cassette. These tubes run down the car's pillars and exit behind the wheel wells. When they become clogged with leaves, pine needles, and other debris, the water tray overflows and leaks into the car.
Pro Tip: You can clear the drains yourself. Open the sunroof and locate the small drain holes in the front and rear corners of the frame. Use a thin, flexible wire (like trimmer line) to gently snake through the tubes and break up clogs. Follow up by pouring a small amount of water into the drain to confirm it flows freely and exits behind the wheel. Do NOT use compressed air at high pressure, as it can disconnect the drain tubes inside the pillars, creating a much worse problem.
Safety Concern: Sunroof Detachment
While rare, there are reports of the sunroof assembly's structural integrity being compromised by rust, leading to the glass panel detaching while driving. This is an extreme safety hazard. Any significant rust around the sunroof opening should be inspected by a professional body shop immediately.
Recalls and Technical Service Bulletins (TSBs)
There are no active recalls or TSBs from the NHTSA specifically for the roof panel or sunroof assembly on the 2004-2006 Scion xA.
It is important to note there is a major safety recall (NHTSA #18V-776) for the airbag control unit, which can cause airbags to fail or deploy unexpectedly. This is unrelated to the roof but is a critical safety issue for all 2004-2006 xA owners to be aware of.
Buying a Used Roof Assembly: What to Check
Since new OEM roof panels are discontinued and expensive, a used OEM part is often the only viable option. Careful inspection is critical to avoid buying a part with hidden problems.
For All Used Roofs (Sunroof or Not):
- Inspect for Rust: Check the entire surface for paint bubbles. Pay close attention to the front and rear edges where it meets the glass and along the side channels. Flip the panel over and check the underside for any corrosion. Surface rust can sometimes be treated, but deep or perforated rust means the panel is junk.
- Check for Hidden Damage: Look for any signs of body filler (Bondo), ripples, or waves in the panel, which indicate a previous collision repair. A magnet can help detect areas with thick filler.
- Verify Structural Integrity: Ensure there are no creases, bends, or deformation from an accident or from being cut improperly from the donor vehicle.
Specific to Sunroof Models:
- Examine the Seal: The rubber seal around the glass panel should be soft and pliable, not cracked, brittle, or shrunken.
- Check the Glass and Frame: Inspect the glass for scratches or delamination. Look closely at the bond between the glass and its metal frame to ensure they are not separating.
- Look for Water Stains: If possible, check the headliner of the donor car. Any water stains are a red flag that the unit leaks.
- Get the Full Assembly: Ensure you are getting the complete sunroof cassette, including the motor, tracks, and drain tube connection points.
Replacement and Installation
Solid Roof Panel Replacement
- Difficulty: 5 out of 5 (Professional Only)
- DIY Feasible: No
Replacing the main roof panel is a major structural repair that is far beyond the scope of a DIY mechanic. The process involves precisely cutting out the old panel, removing the windshield and rear glass, welding the new panel in place, and extensive body and paint work. This job should only be performed by a qualified auto body and collision center. Labor costs often exceed the value of the vehicle.
Sunroof Cassette Replacement
- Difficulty: 3 out of 5 (Advanced DIY)
- DIY Feasible: Yes, for experienced mechanics
Swapping a faulty sunroof cassette with a good used one is manageable for an advanced DIYer. The process involves completely removing the headliner, A-pillar, B-pillar, and C-pillar trims, disconnecting the motor and drain tubes, unbolting the cassette frame, and carefully lowering it out of the vehicle. Installation is the reverse of removal, and care must be taken to align the new unit properly.
Cost Comparison
Replacing a roof assembly can be expensive, primarily due to labor or the scarcity of new parts.

Frequently Asked Questions (FAQ)
Can I add a factory sunroof to my Scion xA that doesn't have one?
No. This would require cutting the main structural roof panel, which would compromise the vehicle's safety and structural rigidity. It is not a feasible or safe modification.
My sunroof is leaking. Do I need a new roof?
Almost certainly not. Over 90% of sunroof leaks are caused by clogged drain tubes. Before considering any expensive repairs, clean the four drain tubes located in the corners of the sunroof opening.
Is it safe to use a pressure washer to clean my sunroof drains?
No, do not use high-pressure air or water. This can easily disconnect the drain hoses from the sunroof cassette inside the headliner, causing water to pour directly into your car's interior and requiring extensive repairs to access and reattach.
What is the difference between a sunroof and a moonroof?
Historically, a 'sunroof' was an opaque, painted panel that tilted or came off, while a 'moonroof' was a glass panel. Today, the terms are used interchangeably. The 2004-2006 Scion xA has a glass panel that slides, which most people would call either a sunroof or a moonroof.
