“Kenworth T680 (2020) Recall: Service Brakes May Increase Crash Risk.” GovInfoNow, updated October 4, 2026. https://govinfonow.com/recall/79757-kenworth-t680-2020-recall-service-brakes-may-increase-crash-risk. Based on NHTSA recall #20V593000 (https://www.nhtsa.gov/recalls?nhtsaId=20V593000).

The brake system uses a standard rear-brake ABS modulator valve instead of a quick release valve. This causes the brakes to take longer to release than intended, which can increase stopping distances and raise the risk of crashes.
