This was $1,100 out of pocket A few days later I was driving and was overwhelmed by the smell of gas. Pulled over, popped the hood and there was fuel leak. Was only 2 miles from the dealer so I drove there and dropped if off. The problem was a leak at # 7 injector. Dealer repaired this at no charge. While in the shop they diagnosed a problem with the #6 lifter which they repaired under warranty Sunday, February 28, 2021.pdfSunday, February 28, 2021 (2).pdf I was informed by the service manager that the p050d code flashed and the now I am being told all of bank 2 injectors need to be replaced. The truck has 48,000 miles on it. The truck is still at the dealership and I am driving a courtesy car. The service manager has escalated this to GM corporate in an effort to find some relief. Standing by for now albeit very frustrated.

Hi All, At 46,032 miles the check engine light came on. Took to my usual service center. They did a fuel injector flush service and this remedied the problem for a few days. Light comes back on, same error. I ran a tank of premium fuel through the engine - light goes off. At 47,300 miles the check engine light is back on. Checked the code = P050D X2. Took to the local GMC dealer - "Performed fuel injector balance test. All bank 1 injectors low". Repair estimate attached. Is this common for 4 injectors to go bad simultaneously on one bank? Or can there be another problem? The truck has a 5.3 engine. Per the service manager this is not covered under any warranties. The truck runs fine- quick start and no discernable hesitations or unusual engine noises. Any direction on a remedy would be greatly appreciated. Regards, John
