Is replacing the seal strip effective for Cadillac CT6 sunroof leaks?
2 Answers
Replacing the seal strip may not necessarily solve the Cadillac CT6 sunroof leak issue, for the following reasons: 1. The seal strips around most car sunroof glass panels are not completely airtight. 2. The waterproofing function of sunroofs mainly relies on the drainage channels and holes around the sunroof track. Here are some details about the Cadillac CT6: 1. Body dimensions: The Cadillac CT6 measures 5184/1879/1472mm in length/width/height, with a wheelbase of 3109mm. 2. Features: It includes a streaming rearview mirror; a four-zone air conditioning system with ion air purification, automatic parking assist, welcome lighting, hands-free trunk release, and an infrared night vision system capable of detecting people and animals at night, along with a pedestrian collision prevention system. 3. Powertrain: It is equipped with Cadillac's newly developed 3.0L twin-turbocharged engine, delivering a maximum power of 400 horsepower (298kW) and a peak torque of 543N·m.
I also experienced a sunroof leak issue with my Cadillac CT6. Initially, replacing the weatherstrip seemed to work, but the leak returned after a week. It turned out that the drainage holes were blocked. Only after cleaning the drainage pipes did the problem completely resolve. So, replacing the weatherstrip can sometimes help, but only if the main cause is aging weatherstrips. If there's an issue with the drainage system, like leaves blocking the channels, water will back up, and changing the weatherstrip won't help. I recommend checking if the drainage holes are clear first—you can use a thin wire or have a repair shop handle it to avoid wasting time and money like I did. Not fixing a sunroof leak can leave the car interior damp during rainy days, leading to mold and damage over time. Preventing it early can save you a lot of hassle.
