Tenneco Automotive (Tenneco) is recalling certain Beck/Arnley Master Cylinders, part number 072-9831, sold as aftermarket or replacement parts for 2004-2018 Volkswagen Jetta, and 2012-2019 Volkswagen Beetle vehicles. The fluid seal crimp on the master cylinder may be insufficient, causing brake fluid to leak or the cylinder to come apart.
If there is a brake fluid leak, it can reduce braking ability, increasing the risk of a crash.
Beck/Arnley will notify the distributors that sold the master cylinders and will work with the distributors to notify the end users. Affected master cylinders will be exchanged for a new master cylinder (part number 072-9990), free of charge. The recall began October 30, 2020. Owners may contact Tenneco customer service at 1-800-625-9319.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
