NHTSA Complaint #11656565 — 2013 CHEVROLET CRUZE

for some strange reason the engine has 150K miles on it and has been extremely well maintained however there is oil blowby coming from the oil filler cap which coats the entire engine belts will slip and cause drivability issues this oil vapor can also coat the front wheel brake discs and soak the pads causing braking failure to occur GM said they are aware of this problem however they do not have a recall to replace the engine or causing issue with the vehicle and i would be better off buying a new GM vehicle rather then worry about this insignificant issue since no accidents have occurred I Maintain my vehicles to the gills something like this is very concerning since this is my wifes car and out child travels in this car what can the NHTSA do to make GM correct this issue on this chevy cruze?
