Got an interesting one for the forum. After the truck (2016 GMC Sierra) has been sitting a while (usually over night or for a few hours) the pedal let's out a nice squeak. On rare occasions I can get it to do it twice in a row, but most of the time the squeak is only for the first press then is gone for all the other presses. Normal daily driving I don't hear it, it's only the first press or when I have to hit my brakes hard (ex, cut off by someone). My local dealer service department (who's treated me well and has good mechanics) looked at it and said they can't repeat it enough to truly diagnose it. Some squeaks are real quick and others last about 2 seconds. The only way I can describe it is like a relief valve letting some air out, but with a squeak. Sometimes I can hold the pedal in place after depressing and the squeak continues to let out. It's not like a metal plunger rubbing on a rubber boot as I depress the pedal, plus I would be able to make the sound every time if that were the case. Below is a video I took on two different occasions, they are looped a couple times. You'll hear what I'm talking about and see that it's gone on the second press. I did have the vacuum pump replaced due to the recall about a year ago, I noticed it after that but the dealership said the pump and vacuum is holding well the entire time, even when it squeaks. They only guess they had was to replace the brake pedal assembly or the brake booster, but admittedly said that would just be throwing parts at it. Just got the truck back today, didn't get charged for the diagnosis since they couldn't figure it out. Now I'm turning to the forum. Any idea what's going on?!?
6.0 low oil pressure.
Aidan Grant posted a topic in 1999-2013 Silverado & Sierra 1500my 6.0 with 230xxx has low oil pressure but no knocks maybe a little tick though. When i bought the truck it had maybe 5-9psi cold dropping to 0 warm. Thought it may have been a pickup tube oring or oil pump so i went ahead and replaced the pickup tube, o ring, and pump. it now gets 20 cold 7 warm at idle and 0 warm at idle and 20 warm running 1700 rpm. Which is a lot better but still a problem. I am aware the bearings may be shot and need a total rebuild, that is not out of the options. It is not electrical or sensor based issue same psi with a mechanical gauge. However I need to replace my harmonic balancer and take off the timing cover again so i was looking at it and could it be as simple as a o camshaft retainer plate? it has a build in thin o ring which if fails will drain pressure as it connects the oil gallys. Am I correct in thinking that this could solve my issues? Any input is helpful, thanks.

Fuel System Fault?
maxxman935 posted a topic in 2014-2018 Silverado & Sierra TroubleshootingHas any one had an issue with their truck stalling an not firing back up? Three weeks ago I took delivery of a 2014 1500 Sierra Denali with the 5.3 and this happened to me yesterday. I had to get it towed to a dealership service center where it still sits waiting for Monday morning when the techs get back in. I was leaving work going about 15mph with a full tank of gas and the engine just shut itself off and would not fire back up. It cranks, but is not getting signal or something to turn the fuel pumps on as they don't chime in with their signature buzz when the key is turned. I tried several different things to try and get the system to restart to maybe get me going to limp home, but none of them worked. Pumped the gas pedal 5-10 times with the key on, disconnected the battery for a short period of time, checked the fuses, tried knocking in a hard manner on the gas tank, and opened and closed the fuel cap. On top of it all, the thing only has 1330 miles on it.... Any words of wisdom for what I should expect the dealership to try and sell me on?
