If not actually the starter, may have been connections to starter, which were all secured correctly and tight with the new starter.  You can only hope.  Good luck and thanx for the the updates.

Still trying to figure out why my Rear Park Assist keeps going in and out.  In the process of checking three fuses and one relay to see what happens.  If it is on when I start up, it goes out after driving a short time.  Makes me think something heats up and causes a short to the system.  No rush to go to the Stealer/Dealer.

Yeah man, can only hope!! It does sound possible, though! Time will tell these next few days/weeks..

as far as your park assist, do you mean, the sensors? The ones that vibrate/beep when you’re backing up?

Rear Park Assist is the dashes behind the vehicle in the DIC when you get close to something, along with triangles in the rear camera that indicate something behind you that change color the closer you get, along with the seat vibrations.  Changed three fuses, no change.  Will change the relay next, then have the wiring harness to each sensor checked, still think there is a short somewhere when the wires heat up.  You can only hope.

Got ya!! Well, on my previous Yukon, the 15’ model, which obviously was the firs gen to include them, I lost them all after first, the right corner  sensor on the front bumper started intermittently getting loose, and freezing solid (while lose after getting out of the car wash, NJ resident) So, while this was going on, I got banged from behind Really softly.. Not even a dent. This was right on the right side of the rear bumper. A few days later, all my assists went off! 
I brought it to my buddy’s body shop for an opinion.. His suggestion was, that both are causing the problem, first Intermittently feom the right side front bumper sensor, and second, most likely  have shut it all down, was the bang in the back Bumper which dislodged/damaged the Park assist module! Which is right in the Right side corner from rear bumper. If you lay down, sneak in under the car slightly, and wrap your hand around it, you be able to feel it. See if it’s loose, or somehow a connection slipped off. (Unlikely) but try it. Mine was all damaged and half hanging, so I’m almost 100% certain that was the culprit. 
To be sure though, check all the bumper sensors front/back, in case any of them is slightly loose or damaged. That will definitely cause it to malfunction as well. 
My solution, at the time, my car had already almost 300k, so I just left it alone, since I got this current one 8 months later. But the problem was there till the day I sold it on Craig’s list. As a matter of fact I explained all this to the buyer. Lol. Keep us posted. ? 

FYI, so far almost a week, no Battery issues!! Truly bizarre, but will see.  Rick!

Good info, thanx.  Still happening.  Have body shop apt next week for new running board.  I’ll ask them to check, and I’ll check/feel the rear connections.

Sounds good. I’m pretty confident that that’s where the problem lies..

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
