The Civics have problems with the piston pin snap rings, and in some situations the cars were manufactured with missing piston pin snap rings. Owners of 1.5-liter turbocharged cars are not affected and the recall of the 2-liter cars hasn’t been officially announced.
Mechanics are being told to inspect the engine’s 4 cylinders using a borescope. There’s two issues, however. 1) There aren’t enough borescopes to go around and 2) If any problems are found Honda doesn’t have replacement parts ready. Other than that, this recall is going swimingly.
