Was driving down the highway last Friday and my CEL started blinking. Car went into limp mode. Prior to this, car was driving fine, no issues. Had it towed to dealer and it showed a misfire code, I think they said 4th cylinder. They said the VPS switch was causing the misfire, and I had a valve that was staying open. Replaced VPS switch and then call to tell me I have a spool valve (front bank rocker??) bad which is causing the valve issue and oil is going where it shouldn't. I can't get anyone to tell me why this is happening on such a new vehicle, and I'm concerned if I don't know the root cause it will keep happening. My husband is deployed, I don't know too much about cars or all the different names for these parts and I feel like I'm paying a lot for parts and labor with no real answers. Any guidance is appreciated. Mileage is around 54k.
