Hello! I myself am from Ukraine! I bought a Chevrolet Malibu 2016 at an auction in the USA. On a 55,000 km run, the piston in the first cylinder cracked. Is there a difference between the 2016 or 2019 pistons? They differ in code! 2016 - 12674549 and 2019 - 12674548! Will 2019 pistons fit my 2016 Malibu ???
Maybe someone has at least some information about this ... Please help me!

Piston design was changed in very late 2017 model year. Oil spec also changed in 2018. I can confirm or get you the part number of the current 2016 piston if you need it.

EDIT: The current/correct piston for the 2016 is 12674549 as you wrote.

The 2019 will probably fit but there is no point. Part 12674549 as you listed prior is the updated design and what you want for your 2016.

But it was not for nothing that the pistons were updated in 2018 ...
And can you please tell me what kind of software update is being done on the official GM service center in the USA?

Will the new pistons and piston rings fit the 2016 engine?
Your images show as being blank. Can you see if they're the right file type and try again, please?

They were updated toward the end of the 2017 model year. It was actually a supplier change as there were batch inconsistenies hence the VIN specific preemptive replacement program. You have a 2016, use the updated 2016 piston. Don't toss in a 2019 as the oil isn't even the same that year.

The service update back in Feb 2017 adjusted how quickly the car advances timing and in what conditions. It also reduced lugging.
