Service bulletin S3672 202311

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Service Campaign: For certain Volvo Trucks configurations an updated adaptive cruise software has been developed. The new software will be delivered as an updated PAR file to the ABS Module and will help reduce heat load on steer axle’s brake assemblies during an adaptive cruise control braking event. Follow the instructions below to visually inspect the brake rotors on the steer axle for excessive heat damage and update the ABS software.
