NHTSA's recall notice
As NHTSA's recall record states it for campaign 21V356000.
Defect description
Roadtrek Inc. (Roadtrek) is recalling certain 2020-2021 Zion, Zion SRT, and Play motorhomes. The undermount generator that charges the Absorbed Glass Mat (AGM) house batteries may have a faulty internal regulator, which could damage the AGM batteries and cause electrical system failure.
Safety consequence
Damaged AGM battery caps can detach. In addition, a damaged AGM battery that is replaced with a lead-acid battery can lead to an acid spill. Either of these scenarios can increase the risk of injury.
Manufacturer remedy
Dealers will inspect and if necessary, replace the undermount AGM generator, free of charge. Owner notification letters were mailed May 26, 2021. Owners may contact Roadtrek customer service at 1-888-762-3873.
Notes
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.
