Haz Posted January 24 Report Share Posted January 24 (edited) SSM 53329 2024-2025 Nautilus - Front Brake Noise Some 2024-2025 Nautilus vehicles may exhibit a grunt-type noise from the front brakes during initial brake applications that goes away after the brakes warm-up. A video demonstrating this condition is available on PTS for 2024-2025 Nautilus under the Service Tips Tab > Reference Guides > Front Brake Grunt Video. For vehicles that exhibit a noise comparable to the video only, refer to the following direction depending on vehicle build date. [ Link To View Above-Referenced Video ] * Vehicles built on or before 13-Jun-2024, that have previously had front disc brake rotors replaced with part number PZ1Z-1125-B: Engineering is investigating further brake noise improvements with a solution targeted for Q3 2025. This condition does not affect vehicle durability and no additional diagnosis or service should be expected to impact this condition at this time. * Vehicles built on or before 13-Jun-2024, that have not had front brake service: replace both front brake disc rotors with part number PZ1Z-1125-B. Refer to the Workshop Manual (WSM), Section 206-03 Front Disc Brake > Removal and Installation. For claiming, use causal part 1125 and applicable labor operations in Section 02 of the Service Labor Time Standards (SLTS) Manual. If the condition occurs after disc brake rotor replacement, be aware that engineering is investigating further brake noise improvements with a solution targeted for Q3 2025. This condition does not affect vehicle durability and no additional diagnosis or service should be expected to impact this condition at this time. * Vehicles built on or after 14-Jun-2024: Engineering is investigating further brake noise improvements with a solution targeted for Q3 2025. This condition does not affect vehicle durability and no additional diagnosis or service should be expected to impact this condition at this time. For brake noise concerns that are not comparable to the video, follow normal diagnostics in WSM, Section 206-00.

Bunky Posted January 25 Report Share Posted January 25 (edited) I have an occassional noise but it sounds more like metal to metal and keep thinking it is corrosion. I watched the video and mine does not sound like that. I P.S. I looked at the rotors and they are truly a disc and not the wider dics with that webbing between the outsides.
