Own 2015 Suburban. Between 1st and 2nd shift causes the vehicle to boog down. Dealership stated " it's a software problem and no up has been put out by GM." Left morrow takes 7.5 mins. to defrost right side takes 2-2.5 mins. Dealership has no idea what the problem is. Anyone having these problems or advice???

So leave it with them and call district , they'll fix it after they get "the call" from district

I don't know anything about the "district". I live in Florida. Do you mean the factory?? It' was a brand new 2015 Sunurban. What I paid for it is not the concern. I just want it fixed. Thanks in advance.

District is the GM "office" in your area. There should be something in the owners manual about what to do when the dealer is not being helpful.

 

You are in Florida and have to use the defrost on the outside mirrors? I am in Canada and have only had to use mine once in 5 years, and that was mid December when it was actually cold. Given that the mirror itself has the metallic content to allow heat to build up, it should be a no brainer for the dealer to simply measure the impedance or resistance in the heated circuit in the glass itself. If I was the mechanic, I would measure and compare the two parts. Seems logical to me that they should be the same value.

We have a bad time with humidity here. It covers everything. I useing the defrost, we can see behind faster. As for thedealership, they used a heat gun to check the temp. It heats up to 118-120. They said that "tach would not have them replace them due to the temp." I offered them to wactch the vidieo that I had taken of the problem. No one including the SM wanted to watch. Even the tech that worked on my vehicle refused to look at it. Still don't know what to do. I'll try the distric office and see what they say. Thanks for your help.

Sounds like a dew problem. Never thought of that. Problem with dew in high humidity is that the air is already full of moisture and does not want anymore.

 

When they tested the temp did they check them both starting at 30 seconds to a minute for the first reading? You know that after 5 min you do not have an issue anymore. They need to test from the start.

 

I have found that driving will clear dew faster than just about anything in non-frost season.

I don't know how they came up with the results. I can ony guess. Anyway they refuse to even try a new mirror to see if it will make a difference. This is all I want them to do. I don't know if GM is aware of this.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
