All I can say is I was in the market for a Yukon because my other one is 20 years old. I had two years of research false starts and close calls before I finally bought the one I did. I probably passed up on over 10 vehicles mostly used CPOs for demos that I was as close as 30 minutes to walking in and sign in the paperwork when I bailed out.How did you determine that the majority of failures occurred with the vehicle being driven 60 - 75 mph?
How did you determine that a non-technical senior tech “probably” made the decision (recall?) after looking after their bonus and the stock price?
Any facts or proof?
As far as all the failures at highway speed all you have to do is you research. I have spent probably in excess of 100 hours researching these failures. And understand bearings typically don't spin at low RPMs and low loads. The 6.2l is under massive load at low RPM at highway speed. I have pulled and graft data on multiple runs that show engine loading 70 to 100% pulling slight grades on the highway between 1,500 and 1,700 RPM. Conditions ripe for spining bearings.
As far as what's going on with GM, I can only speculate but I did used to work there so I kind of know what happens. Some higher level executive management people clearly decided on the first round let's go with the cheaper option oil change. But I would bet you comments from people like me on this forum all over social media Reddit other forums probably were picked uip and somebody said oops we're going to have a mutiny on our hands.
This along with the upcoming valve body problems is probably going to cost GM close to $5 billion dollars.
I'm one of the lucky few that has an engine build date of July 15th 2024 and I hope it's okay, The stuffed shirt talking heads tell me it's okay!
I am just absolutely shocked and flabbergasted The GM let this go on as long as they did. They knew there were problems way before this particular one. The QA is going out the window I'm not sure what went wrong and why. We can only hope even though the 5.3l haven't seen this level of problems and were built at different assembly plants it's actually a kissing cousin of the 6.2l. it's possible the 5.3l may have some similar problems but not to the extent. A lot of it has to do with the fact that the 5.3l isn't put under the extreme loading on a regular basis as the 6.2l.
I'm not necessarily a fanboy of GM but I'm trying to help everybody else out here that's bought one of these vehicles to keep it alive and well or as long as they can. We all spent way too much freaking money on these things to go through this garbage
