Both mine and wife's cam sensor died at about 125,000. Neither have had crank sensor replaced. They are scary sensitive to wear related variance of output. The engine computer is convinced a cylinder didn't fire if it detects a slight delay in the next anticipated pulse from the sensor.

I've only replaced the intake side cam sensor it appears that's typically the first to go.

I only got CEL and occasional shut down though so based on you getting failsafe I'd wait for a little more feedback maybe somebody else had similar conditions.
