I have a 2017 Titan XD Diesel 9/17 Has anyone had the hard shifts and loss of power problems? I took it in a few months back because I was pulling my boat and loss power completely and dropped to 30mph check engine came on and slightly regained power, enough to get it to the dealer code P226C so they replaced some turbo actuator or sensor I don't know. So while I had it there they replaced the platinum reserve emblem on the tailgate because it was falling off and titan boxes for the hinges breaking(rivets failing) and checked the audio amp because it overheats and cuts off. Well I picked it up two weeks later and it was shifting hard and really sounded like too much pressure building during shifts nasty shifting as well and killed on me at a red light. Ive noticed also I let off the pedal and press again it sounded like a bird chirping. I bring it back in (no codes) and tell them about the pressure building sound occasional on shifts and the bird chirping sound releasing and pressing the pedal also the hard shifting. Same day I get a call and as usual I get the routine "everything is operating as it was designed" or "Everthing is operating normal." I said come on guys y'all cannot tell me this is normal!!! So I left nonetheless pissed beyond measure! Later that day the truck downshifted really hard and made a funny sound and up comes the check engine light! But everything is normal right? Well i plugged my OBD2 reader and guess what? The same code that was fixed before P226C, Now they want to change the whole turbo! Can anyone shed some light who has had turbo replacements? Whats going on with these trucks? Should this engine have a better single turbo set up? Seems like a huge problem!
