2012 Champion Challenger Engine problems

I was driving down on the highway and felt the vehicle hesitation. The vehicle won't pass inspection due to cylinder 5 misfire. There is a delay and a jerk at times when accelerating. Cylinder issues cover for the left side of engine is not covered for the right side of engine. This is not right. There was a manufacturing problem with the 2012 cylinder heads etc. I'm now being told it only qualifies for the left cylinders and not the right ones. This is fundamentally wrong. All possible defects due to manufacturing issues in all cylinders should be covered as long as my vehicle is under extended warranty requirements
