There are some pretty simple steps to take if you own one of the vehicles affected by the recall. First, if you own a Solterra, RZ, or bZ4X, you'll want to plug your VIN (Vehicle Identification Number) into NHTSA's search engine. Once they've identified their vehicle as a part of the recall, owners can contact Toyota (yes, even the Subaru owners) at 1-800-331-4331. Finally, the Subaru Solterra uses the recall number WRD-25. Subaru, Toyota and Lexus dealerships will install a free software update for customers to address the issue.
