Truck Specifications:

2018 Silverado

LTZ

6.2 Motor

27K miles

Rebuilt title: interior fire damage to left passenger seat, no external damage, only passenger seat and door panel replaced.

Warranty: 3RD Party warranty

 

**I randomly get a tick/tapping sound from the passenger side of the vehicle. I've taken it to the dealer multiple times, haven't been able to reproduce it and said everything is in normal operating condition. Took it to a muffler shop looking for any issues with the manifold and was told that everything is all good. Just doesn't sound normal whatsoever, has anyone had this noise or any idea.  Please let me know, not sure what to do since it doesn't do it consistently.  Videos are attached.

I would say its lifter tick. But really it could be the high pressure fuel pump or the vacuum pump. Send that video to the service manager and tell him you want that crap fixed!

 

Or put headers on. There will be so much ticking you wont know whats what and it wont bother you anymore.

Thank you for the response! I forgot to mention in the first post. When the dealer had the vehicle they it was the high pressure fuel pump and vacuum pump activating. 

 

1. If that's correct why don't I hear it more often?

2. I'm not sure if the loud noise ever produced while the dealer had the vehicle.

 

Any thoughts if its the fuel pump or vacuum pump? Just doesn't sound like that noise would be standard in my opinion?

The closer the part is to failing the more consistent/louder it will be. It's sad but true that they purposely don't replace parts until they consider them to be bad (about to fail).

Lol that’s a lifter tick if I’ve ever heard one

And I have

I do this for a living

You gonna be having lifters replaced one day

But if they aren’t locked or whatever there’s nothing you can do. If it were mine...I’d just wait until they fail there’s nothing more to do. Could be another 80k until you have an issue honestly.

So is this something I just wait for it to be consistent. It’s happened roughly 5 or 6 times since august. Is their an oil additive to try?

Just wait for it to lock up and bend a pushrod
Then I get paid to fix it
You can add a mason jar full of diesel fuel if you don’t want to listen to it anymore but I’d just let it ride.

The ticking at times will sound almost normal at idle, but when I rev the RPM’s up the ticking will increase in sound. If it’s a lifter, will the sound increase with rpms going up?

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
