This doesn't mean that Mazda vehicles are going to dry up overnight, though. The automaker says that the ordering would only cover vehicles to be allocated for May, and that the company has decent vehicle stockpiles for U.S. buyers. As of right now, there's no indication as to when ordering will resume.
Mazda is reported to have had a 93-day supply of vehicles on dealer lots at the beginning of this month. While that figure is down from a 123-day supply in February, Automotive News says that a 60-day supply is considered normal for the industry. The automaker currently imports the Mazda2, Mazda3, Mazda5, MX-5, RX-8, CX-7, and CX-9 models
