lordathey replied to The.Sundae.Drive's topic in How-ToPerfect timing! I'm going to change all these fluids tomorrow and your videos are going to speed up the process. Thank You!
Well that's good. I personally like the suburban over the truck, but I'm glad they are taking care of you. Some dealerships will have issues with a tune and others won't, but it also depends on the logs that GM wants pulled from the ECU and or TCM. I waited until mine was out of warranty to do the tune just to be safe.
You will be losing a ton of money trading in that suburban. I would just keep driving it because the issues you have had aren't that bad. It sucks that its happening on a new vehicle, but at least you know you got new parts :). It took me going back to the dealer several times for a coolant leak and it ended up being a bad cylinder head. It was a pain to make them actually find the issue, but it finally got resolved. The stock transmission tune shifts like crap and it will be that way of the truck too. I just got a blackbear tune and my truck's shifting is night and day.
Perfect! Thank you for the information. I have a 2014 as well :). I was going to change my rear diff fluid here in a couple weeks, but I'm going to check the axles first before changing the fluid. Did you reuse the axle bearing and oil seal or did you get new ones?
Long story short my dealer was no help at all. They replaced my driveshaft and road force balanced the tires. At first I thought it was the crappy Goodyear tires, but I got Michelin's and the problem was still there. Just had my driveshaft balanced per the forum. It was a iron driveshaft and the guy could see where it would shake at high speeds. Got that correct and the shake is worse..... not bad, but worse then before. I'm going to measure the axles to see if they are out of round next. Can you tell me the Yukon axle and wheel stud part number? Also what rear end do you have? I have my fingers crossed that the axles are the problem! Thanks!

A new engine because of a bad cylinder head? My cylinder head in my truck had a crack at 10K and after some back and forth at 25K they replaced it. I have had zero trouble and my truck is at 40K. It sounds like the cylinder had a defect and they are replacing it. You can try to argue for a new engine, but I don't think a leak on the outside of the cylinder head is cause for a new engine. Keep us updated.
Also when they pressure checked the system they didn't find anything because they did it cold and the crack wasn't opened. They finally found it after I made the service writer come out to my truck and acknowledge the smell of burning antifreeze. Good luck! I hope its fixed!
its a 2014 and actually the bumper to bumper picked it up. First time it went in was at 12,000 then at 18,000 then at 21,000 and they finally fixed it. If I was out of my bumper to bumper the powertrain would have covered it. I ask the service writer about being out of the bumper to bumper and that's what he said.
