What to do if your Honda CMX300 is on this list

A recall listed here applies to a range of vehicles, not to every car of that model year. Manufacturers narrow it down by build date and VIN, so the only way to know whether yours is included is to check the VIN. You can do that free on NHTSA's recall lookup, or by calling any franchised dealer for that brand with your VIN in hand.

Recall repairs are free. Under federal law the manufacturer has to fix a safety defect at no charge, and there is no mileage limit and no expiry on that obligation for vehicles under 15 years old. A dealer cannot charge you for the parts, the labour, or the diagnosis on a recall repair, and you do not need to have bought the car there. If a dealer asks you to pay, that is worth escalating to the manufacturer's customer line, which is listed in the remedy text of each recall above.

Recalls do not block a title transfer or registration in any state. You can legally buy, sell, or register a car with an open recall, and sellers are generally not required to fix one first. That said, an open recall is worth raising before money changes hands, especially one with a do-not-drive advisory. If you are buying, run the VIN before you hand over the payment; if you are selling, telling the buyer about an open recall costs you nothing and avoids a dispute later.

Honda CMX300 recall questions

How many recalls does the Honda CMX300 have?

NHTSA lists 4 recall campaigns for the Honda CMX300 across model years 2018 to 2025. That count covers recalls filed from 2010 onward. Not every campaign applies to every car of that model year, because manufacturers limit recalls by build date and VIN.

Which Honda CMX300 model year has the most recalls?

The 2023 Honda CMX300 carries the most, with 2 recall campaigns. A high count does not automatically mean a worse car: a single supplier fault can trigger a recall across an entire production run, and manufacturers that report problems quickly tend to show more campaigns.

Are Honda CMX300 recall repairs free?

Yes. Federal law requires the manufacturer to repair a safety recall at no cost, including parts and labour, on vehicles under 15 years old. There is no mileage limit, and you do not have to be the original owner or have bought the car from that dealer.

Can I sell or register a Honda CMX300 with an open recall?

Yes. An open recall does not stop a title transfer or registration in any state, and private sellers are generally not required to repair one first. Dealers face stricter rules on some safety recalls. If you are buying, check the VIN before you pay; the repair is free, but you want to know what you are taking on.
