2013-2015 Honda Crosstour Tail Lamp: Water Leaks, Replacement, and Used Buying Tips

Symptoms of a Failing Tail Lamp

Failures in the Crosstour's tail lamp are typically related to the housing itself or the bulbs within it. Here are the most common signs that your tail lamp needs attention.

1. Condensation or Water Inside the Lens

Seeing moisture, fog, or a small pool of water inside the tail light is the most common failure symptom. This indicates that the factory seal on the lamp housing has failed or the foam gasket between the lamp and the car body has degraded. While a temporary fix involves drilling a small drain hole, this is not a permanent solution and the lamp should be replaced to prevent electrical issues. Moisture inside the housing will cause chrome reflector surfaces to corrode and will lead to frequent bulb and socket failure.

2. Dim or Burnt-Out Bulbs

A tail light that doesn't illuminate can often be fixed by simply replacing a bulb. These Crosstour tail lamps use standard, replaceable incandescent bulbs (size 7443 for tail/brake functions), not integrated LEDs. However, if bulbs seem to burn out frequently in one housing, it's a strong sign that moisture is getting inside and causing corrosion or short circuits. Before assuming the housing is bad, always test with a new bulb first.

3. Cracked or Damaged Housing

Physical damage from minor impacts is a frequent reason for replacement. Even a small hairline crack can allow water to enter, leading to the issues described above. A broken housing is a safety issue, as it can affect light output, and it will fail a state safety inspection.

Known Issues, TSBs, and Recalls

As of mid-2024, there are no active recalls or Technical Service Bulletins (TSBs) from Honda or the NHTSA specifically for tail lamp failures on the 2013-2015 Honda Crosstour. All existing recalls for this vehicle pertain to the airbag systems. While no official bulletin exists, water leaks from aging tail light gaskets are a well-documented issue across many Honda models from this era, often leading to water in the trunk.

Buying a Used Tail Lamp: What to Check

A used OEM tail lamp is often a better choice than a cheap aftermarket alternative due to superior fit, plastic quality, and color matching. However, you must inspect a recycled part carefully before purchasing.

• Check All Mounting Tabs: Carefully inspect the back of the lamp. There are several black plastic mounting tabs and studs that secure it to the car. Ensure every single one is present and free of cracks. A broken tab will cause the lamp to fit loosely, vibrate, and eventually leak.
• Inspect for Hairline Cracks: Hold the lamp up to a light source and examine the entire lens surface, especially around the edges and corners, for fine cracks. What looks like a scratch could be a crack that will let in water.
• Look for Signs of Water Intrusion: Check the inside of the lamp for a faint white line (mineral deposits) at the bottom, which indicates it has held water before. Look for any discoloration or corrosion on the silver reflective surfaces.
• Verify the Gasket's Condition: The lamp should come with its foam gasket on the back. It should be pliable and not flattened or brittle. If it's in poor shape, you may need to source a new one to ensure a good seal.
• Confirm the Part Number: Double-check that you are buying the correct side. Part numbers are typically molded into the plastic housing.
  • Right / Passenger Side: 33500-TP6-A11 (or 33500-TP6-A01)
  • Left / Driver Side: 33550-TP6-A11

Replacement Guide (DIY)

Replacing the outer tail lamp on a 2013-2015 Crosstour is a simple job that requires basic tools and about 15-20 minutes per side.

Tools Needed:

• 8mm or 10mm deep socket with ratchet
• Plastic trim removal tool (or a flathead screwdriver wrapped in tape)

Step-by-Step Instructions:

1. Open the Trunk: Access the area behind the tail lamp you are replacing.
2. Remove the Access Panel: On the side of the trunk liner, there is a small square access panel. Use a trim tool to pop it open.
3. Disconnect the Wiring: Reach inside the opening and locate the main electrical connector for the tail lamp. Press the tab and pull to disconnect it.
4. Remove the Mounting Nuts: Inside the opening, you will see two nuts (typically 8mm or 10mm) holding the tail lamp assembly to the body. Remove both nuts.
5. Remove the Tail Lamp Assembly: The lamp is now held in by a plastic locating pin on the side. Gently but firmly pull the assembly straight back, away from the car, to release it. Do not pry against the paint.
6. Transfer Bulbs (If Needed): If your replacement lamp did not come with bulbs and sockets, twist your old ones counter-clockwise to remove them from the old housing and install them into the new one.
7. Install the New Lamp: Align the new lamp's mounting studs and locating pin with the holes in the body and press it firmly into place. Re-install the two nuts from inside the trunk and tighten them until snug—do not overtighten.
8. Test and Finish: Reconnect the electrical plug. Before closing everything up, have a helper confirm that the brake lights, running lights, and turn signals all work correctly. Replace the access panel.

Cost Comparison

The cost to replace a Crosstour tail lamp can vary significantly depending on the type of part you choose.
