The 2014 Chevy Impala is dangerous. When the rocker arm control valve and related parts fail or the camshaft solenoids and sensors fail the car will drive rough and eventually just cut off in the middle of traffic highway or residential. This is what it did on me, putting me in a very dangerous position. The economic loss is still devastating financially as all 2.5 and 3.6 engines arent covered by GM special warranty but they should be all covered. My VIN number was not included when it should be.
