NHTSA Complaint #11596526 — 2017 CHEVROLET SILVERADO 2500

Another day another code. P11DB (NOX upstream). Now I am at NOX downstream, NOX upstream, DEF pump, cylinder 7 wire connector, Trailer Brake Controller wire harness, temperature sensor, and a dozen chafing wire harnesses because they are pulled to tight, have extreme bends in them or are rubbing against the frame, bumper, etc. Chevy recommended that I replace the cylinder 7 injector which was not the issue. At this rate if I paid Chevy to diagnose and repair this vehicle I would easily be $5,000+ in repairs since Chevy wants to do cab-off maintenance on everything now. This is manufacturer defects and consumer fraud and NTHSA is not holding Chevy accountable for. My Dad has a 1978 Pinto that he can start up and run to town but my 2017 Silverado can't even leave the farm.
