So lets start this story with buying the 2017 silverado LTZ Z71 Jan 19th of this year. 34.5k miles on it. Drive it for another 1.7k miles and get a check engine light scan it myself and get codes p0300 and p050D... great probably lifters or something right? Take it to dealer they get same codes then tell me that 2 injectors in cylinders #4 and #6 are bad and need replaced. They say 1,100 for the injectors will take another week to get them in and replace. Wait the week and get a call they replaced the injectors... started the truck... and per the service guy "something broke loose from bottom of engine". Wait another week, brings us to today, get a call that now I am getting an all new Engine. They found pitting in both cylinders 4 & 6 they say probably from the malfunctioning injectors. I ask about what he meant by "broke loose" and he just says they aren't 100% sure what happened but new Engine none the less. Now I get to wait another 2.5 weeks for engine to arrive and be replaced. I am so very curious how a 36.1k mile truck can have that bad of a problem that the WHOLE ENGINE would need replaced lol. I'm glad I am no longer out any $ but still... its so curious.
