Summary
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.
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.
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.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Roadtrek been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Roadtrek dealer can also check your VIN. Recall repairs are free.
