Manufacturers are required by law to provide parts for a minimum of 10 years. Daimler has one of the better track records regarding parts availability, providing parts often for many years. We won’t know for certain until time passes. I have a 2016 Passion and am not concerned. I still easily find parts for my 1977 and 1990 Benz sedans.
Myth: 10 year parts law?

While you can still find parts for your cars. I have tried my best "Googlefu" and can find the Printed Law requiring manufacturers to
provide parts for a minimum of 10 years. Perhaps you can provide a link. The only thing I can find is the following.
Orphan Cars And The 10 Year Parts Myth. I believe our ICE smarts are now Orphans.
By Bozi Tatarevic on July 17, 2015
Every automotive enthusiast has an opinion when it comes to car buying and many are quick to point to an orphan car for a good deal. While some orphan cars are a bargain for their genre, maintaining some of them can be an exercise in futility. Internet commenters and forum aficionados are quick to defend their recommendations and point to some parts law that supposedly forces manufacturers to provide parts for 10 or 20 years after they kill a model, but no such law exists. While there are laws like the Magnuson-Moss Warranty Act that provide some protection in certain situations, it’s nowhere near the 10-year mark.
According to the FTC, the Magnuson-Moss Warranty Act provides rules on warranties for all consumer products, and in the automotive world it forces automakers that provide warranties to produce parts for the term of the vehicle warranty. In some cases this can be as short as 3 years after the sale of the last model. Once that term is up, they do not have any further obligations to the consumer. The entity providing the warranty can also choose to stop manufacturing parts before the warranty expires, but in that case they may be liable to replace the product or provide a refund.
The other piece of the warranty puzzle is emissions coverage that is mandated by the EPA that provides for 2 years of coverage for any emissions performance issues and 8 years of coverage for any defect related to the emissions system.
While this coverage is notably longer than the usual powertrain warranty, it does not necessitate that the manufacturer must provide parts or service. It only states that they must cover the cost of any required repair.
