I got a 2015 Silverado 5.3l. 138,250km. started ticking sometime last winter. Would happen instantly at start up and last about 5 minutes then would fade away. Sounded like a lifter. Took it to the dealer they said they couldn't hear it. Sound went away so left it.
Fast forward to this winter and as Soon as the weather started to cool down I noticed the ticking again.
Took it back to the dealer said they couldn't hear it again. I went and picked up my truck right at closing, soon as I fired her up the sound was there but everyone was gone so no one to hear it. I took a video. Next day I called the dealer, sent the video. Took like a week to get back to me. In the meantime I had taken videos pretty much every time I started it.
Long story short after a brief fight with them about them trying to say it's normal etc they agreed that it sounded like a noise coming from the valve train. Left my truck with them, they called me said they had to change all lifters. Went to pick up my truck and on start up the sound is still there.
This was a month ago. Sent more videos and a previous video from before they did the work and they are saying they can't hear it again.
Took it in in person they agreed that there's an issue again and they will look at it. Now they are saying it's possible bad injector noise but they can't figure out which one 🙄.
In the meantime I took it to another dealership they changed the vacuum pump. After that the sound changed. Now it's no longer at start up but once the truck has reached operating temperature and is more of a dull sound. Took it back to that same dealer who did the vacuum pump and they said valve train noise and deffo not injectors. But they won't work on it because the other dealer already did.
They didn't change the VLOM or the cam. I had/have no check engine lights. Truck runs awesome. Sometimes rough idle.
Any ideas what it could be?
Please help I have been to the dealer multiple times in the past few weeks for my 2019 Chevy Colorado. They are struggling to fix this issue and no one really knows how to fix it. It keeps saying the SD card for Navigation has been removed when it hasn't been. I have an iPhone X latest update. The bluetooth comes and goes too when the navigation does. Bluetooth for phone calls will work but music won't play and I have even tried my moms older iPhone and it still does the same thing. The dealership has replaced the SD card, the whole front USB port, and the radio system unit. It still did it today and bluetooth music comes and goes like the SD card reader error for navigation. Any one else experiencing anything on any GM cars?? I also have the latest version of the infotainment system and I'm wondering if the update messed is messing it up like some kind of bug.

I have a 1997 chevy suburban 4wd and while in 4wd it was making a loud clanging noise when accelerating in 4wd hi or 4wd lo. Anyways everything underneath was tight and no play. I couldn't figure it out. It has the dash 2wd 4wd hi and 4wd lo electric switch it wasn't flashing while in 4wd hi or low and you could hear an engagement sound when 4wd selected. I thought it maybe it was the front crown and pinion gear missing a tooth. I took it to the mechanic and it was the 4wd actuator! I guess it was gimped up and engaging and disengaging while in 4wd and making a horrible clanging noise. Anyways I replaced the actuator myself a few years ago (which was possibly the easiest repair ever) but the 4wd light was flashing and it wasn't engaging at that time. Anyways it cost me a fair bit more to have a mechanic diagnose and then replace the actuator but if it happens again I'll know what it is. Also I may be able to help someone else searching online for an answer. It's a fairly cheap fix to do yourself and super simple to do. About $60 from 1aauto! Hope this helps someone out.
I'm interested in a quick read of the room. How does everyone feel about the news that GM is moving in the direction of an battery electric truck? Does the brand it's sold under influence if you'd be interested? Are you ready to buy one now or do you think we should wait it out?
Thanks for your opinions!
