How to Solve the Sunroof Rattle Issue in the 2012 Camry?

Solution for the sunroof rattle in the 2012 Camry: Prepare the necessary tools, including a flathead screwdriver, lubricating grease, and tissue paper. Press the sunroof switch button to open the sunroof. Use the tissue paper to clean the dust from the groove under the sunroof's front deflector. Press the front deflector by hand to check if it moves smoothly without any tightness. If it feels tight, apply some lubricating grease into the groove. The Camry is a mid-size sedan with dimensions of 4885 mm in length, 1840 mm in width, and 1455 mm in height, and a wheelbase of 2825 mm. In terms of suspension, the front suspension uses a MacPherson strut independent suspension, while the rear suspension employs a multi-link independent suspension.
For the issue of sunroof rattling in the 12th-gen Camry, I believe the most common causes are excessive dust accumulation on the sliding tracks or insufficient lubrication. Having repaired several cars myself, I recommend first using a soft-bristle brush to remove dust and debris from the tracks, paying special attention to small crevices. Then apply a layer of dedicated sunroof lubricant—avoid using regular engine oil to prevent part damage. After application, operate the sunroof several times to test; the noise usually disappears. If the rattling persists, it might indicate internal component wear, such as loose guide rails or screws, requiring thorough inspection and tightening. If simple DIY methods fail, I strongly recommend professional diagnosis at a 4S shop. They can identify potential issues and address them promptly to prevent sunroof leaks or more severe failures. Regular sunroof cleaning during car washes can minimize such problems.
