Cause The parking sensors are detecting the front brush guard. Remedy Complaint must be consistently reproducible and can occur multiple times a key cycle without obvious cause. NOTE: The parking system serves solely as an aid. Please review both the system function and system limitations as shown in the Operator's Manual. Certain environmental factors can affect system functionality such as hot exhaust gases or extreme heat, sensor interference, or other outside influences or aftermarket modifications. If after verifying the complaint is consistently reproducible: 1. Determine if the complaint is reproducible only in high ambient temperatures. If complaint does not occur in cooler ambient temperatures, it is due to system limitations. You may proceed with the below work but the vehicle may be released afterwards as it is due to system limitations. 2. Remove the brush guard and verify the park distance sensors function as expected. 3. Reinstall brush guard and adjust so that it is as far away from the park sensors as possible. Typically only small adjustments are possible. 4. Check function. If the concern is still consistently reproducible, please apply clear matte film to the locations as shown below at a minimum, although the clear matte film may be applied to the whole brush guard. Picture: Above shown is the 465 brush guard variant. Although similar to the 463, there are some key differences such as the 465 being fitted with a front camera.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11035219-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11035219-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11035219","components":[{"id":"structure-body","name":"Body and frame","parent":null},{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"backup-camera","name":"Backup camera","parent":"driver-assistance"}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES BENZ","model":"G500","year_from":2002,"year_to":2008,"match":null,"vehicle_ids":[]},{"make":"MERCEDES BENZ","model":"G550","year_from":2009,"year_to":2009,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG G 55","year_from":2003,"year_to":2004,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG G63","year_from":2013,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG G65","year_from":2016,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"G550","year_from":2010,"year_to":2011,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"G550","year_from":2013,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"G63","year_from":2013,"year_to":2017,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
