That much I couldn’t tell you... possibly poor quality control.. they should last the lifetime but being the first gen s550 I’d expect some weak pointsExcellent info - and for whatever reason there seems to be a rash of melted cooks and PCM failures.
Is the PCM getting wet from water intrusion somewhere? Why would the PCM be failing so early considering most last the lifetime of the vehicle?
