Issues started with delayed starting. Takes 10-15 second continuous cranks to start. Showed it to one garage. They scanned and confirmed fuel pump gone and gave quote 24k + labor. Told them to replace diesel filter, which was not replaced by Continental, whom did the last major service. There was smudge formation and virtually no fuel flow.
Took it to Chevy dealer to confirm fuel pump issue. Knew a guy there, he kept car for 3-4 days there and checked thoroughly and finally concluded not the pump, but the turbo is gone. Reason being oil sump hit and damaged and strainer damaged and no oil flow at all. Actually no oil at all, all burnt up, damaging the turbo.
Final estimate was 62.5k and offered to do it for 60k. Turbocharger costs around 15k. Oil sump needs replacement. There is blow by gas and suspect need for engine rework.
AC unit fully clogged, also thanks to Continental for not changing AC filter despite specific request. It's making annoying noise with debris inside the blower.
Warranty void as we did not do service at ASC. Unfortunate that car bottomed some pothole and damaged the sump.
Took the car from Deedi. Even after thorough inspection, they didn't charge for anything and final bill was 0. Also they filled oil from a low odo Beat temporarily.
