My vehicle was in motion on the highway at an approximate speed of 65mph and suddenly I heard a strange pop. My car immediately went into limp mode causing my speed to drop to 25mph on a moderately crowded interstate highway. Due to the dangerous nature of this issue, I drove on the shoulder to the closest exit and drove the car to the closest dealership. 6 different trouble codes were pulled on the vehicle. I purchased my vehicle less than 6 months ago along with a gmpp extended warranty. For two weeks, the warranty could not be found and I was calling numerous warranty companies trying to find out what occurred with my warranty. After the 2 weeks of calls and confusion, the dealership stated that they would cover the pcv valve issue that they had diagnosed to be the problem. The dealership never stated that the pcv valve malfunction was in fact a "special added protection issue" put out by gm in august. I finally received my vehicle back two days ago and the car is still not working as it was before this repair. It is idling hard and at high RPM and also hesitating during acceleration.
