So.. I have a 2020 High Country 3500 HD Duramax. I have had 4 injectors replaced for a miss fire. Tried to tell me it was from the bad fuel. Also had a transmission leak out the front ( thought it was the converter). Also the engine oil filter housing was leaking. The steering column Intermediate shaft replaced for the clunk in the column. Just got it back AGAIN. The service writer said there is no fix. I spent 78K for a problem truck. NOT happy. I own a shop. I'm going to look into it! Just didn't want to void warranty. THAT'S why I bought a NEW truck so I wouldn't have to fix it.. hhhmmmm we will see if i can figure it out..
