So in February I bought a clean 2016 Double Cab 1500 Z71 Silverado with 33k Miles on it. The odometer is at 36500-ish miles, and yesterday morning it was shifting hard, not as much power and the check engine light came on. I went to Auto Zone and pulled the code P219B which is a bank 2 air/fuel in balance. I took it to the dealer and made a appointment for it to be worked on. I purchased the Platinum protection package and the power train warranty is still in coverage, but if it's a bad O2 sensor or fuel injector I'm not sure if I will have to pay out of pocket, which is frustrating considering the truck JUST went out of bumper to bumper warranty and I just bought the truck a few months back so needless to say I'll be pissed if they make me pay out of pocket for a repair.... Today however, the CEL is still on but driving the truck to work was driving as normal again and I was getting 17.7 MPG in the city, which yesterday it was getting between 12-14 mpg. I'm hoping that maybe it was just bad gas, but this is really irritating to say the least. Sent from my Pixel 2 XL using Tapatalk
