When I left the dealership the day I purchased the truck the Check engine light came on. Took the truck in a couple days later and they diagnosed it as a bad o2 sensor. They replaced it the next day, no big deal right? Except when I picked it up the light came back on at the same point in my drive.

 

I've now owned my new truck for 9 days, it's been in the shop 4 of those days. It has <400 miles on it. They've now had it for the 3rd day of troubleshooting and still don't know what is wrong.

 

Is a example of the trouble that is to come with this truck?

Hello Kidrcrh,

 

Owning a new Silverado should be an exciting time! However, I know this isn't what you expected, especially so early into your ownership. Please send us a private message with your VIN, mileage, contact information, and dealership. Once we have this info, we’ll reach out to your dealership to gather more information on what they were able to find. We’re looking forward to hearing back from you!

 

Best regards,

the issue is now getting worse. My truck will have been fingered with by the cheapest mechanics a dealership can afford They have replaced the ECM and replaced everything they can think, now they are blaming it on a wire. A wire repair on a brand new truck should be a harness replacement. Not a repair. However that is not the case.

 

I will PM you my information. But please note, paying sticker price for a vehicle that was broken on the showroom floor, and now i will never of had a 100% NEW truck in working condition.

i want to believe the opposite, however, i still haven't received my truck back. It sounds like there is mass confusion as to what the fix is and they just keep throwing parts at it.

 

I have been a GM owner my entire life. When i was 18 and dumb i got an AC Delco spark plug tattoo'd on my arm. I am a Chevy guy, this is just ridiculous.

The problem may be in the wiring itself and that will be difficult to find.

they diagnosed a open wire between the o2 sensor and the pcm last Thursday. Somehow, they still havn't fixed it.

 

I diagnose and repair wires on aircraft for a living, do not even try to tell me its hard. there are tools for everything, a TDR can tell them exactly how far into the wire a break in the shielding is, let alone an entirely broke wire. This is mismanagement of assets. If it took me 5 work days to repair or replace a wire, I had better have a good excuse or my but is fired.

      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!
