My cold start knock/tick issues continues "no repair available"

ericgcsc · October 25, 2019

Hello,

Back in july I bought my 2019 GMC Sierra 1500 SLE, I have the same issue as you, its going in Tuesday for them to "look at it". But I can guarantee ill get the same run around. It is very disappointing thinking it was going to be a good truck since my 1995 Yukon 5.7 is going strong still.

Let us know how you make out. There have been a few people that actually got the dealer to replace the lifters but it didn't fix the noise.

What's the latest updates from you all on this issue? Been about 3 weeks with no responses. Be interesting to see if anything's being done from a bleacher perspective as I only have a 04 Tahoe with a 4.8 that started doing it when cold but I just think mine is the exhaust manifold gasket getting worse. 3yrs and going with a broken drivers side rearmost bolt.

The Issue we are referring to is listed in the bulletin as 2018, 2019 5.3, & 6.2L V8s. But to answer your question GM has done nothing and it has become a legal matter that my attorney has advised me not to talk about on social media or at all really.

I leased this truck( with intentions to buy it at the end as long as it wasn't a turd). The current buyout from GM is around 39k. Trade in would be low 30s I would assume. I cant really afford a 10k hit right now. My last 16 was a shaking turd. I should have learned my lesson but all other brands just don't do it for me. Should have bought a Toyota.

Best made tanks on the road, and Ive worked for Ford, Ram, GM and yota.

I am surprised no one has had this issue on here yet. I guess if you just hop in a drive and don't listen to it warm up outside the truck people may not hear it.

Here's mine more of a tick brand new sierra,but only notice the sound if it's in the garage

That noise is normal most of these trucks do that. my 16 and my 19 do. My noise is more of a loud knocking for the first 10 mins of cold start up

Had a similar tick from my 2019 Silverado RST with 2.7L 4 cyl. with 8 speed transmission. Noise as the engine came off cold idle. Then it progressed to ticking while accelerating from a stop. First the dealer said lifters, then said the flex plate (flywheel) was bad. Replaced it but noise was still there. Spent 3 weeks working with a factory tech, even reprogramming the computer. With no luck. Then the transmission tech noticed the service bulletin for the flex plate (19-NA-154) also mentioned the starter. When he pulled it he could hear loose parts rattling around. Replaced it and all is quiet, so far. And it only took 8 weeks to realize the starter was bad.

Mine makes the exact noise but quieter. Very strange and definitely not normal. I have 10k miles on my truck and just noticed it a few weeks ago as the mornings got colder. Based on my experience working on engines, this sounds dangerously close to light rod knock and/or piston slap. Disappoints me that I spent 40k on a truck that has this issue without even owning it for a year. Will definitely take it in to get it looked at and hopefully fixed ASAP under warranty. I would encourage anyone else with this issue to do the same immediately to bring this to GMs attention and at the very least have it on paper that your truck has this issue.

There is no fix for it. If the knocking noise goes away after 10 minutes of idling GM wont do anything. At about 12k miles my truck started to idle noticeably rougher(felt like a misfire). Again Gm wouldn't do anything to fix it. I ended up lemon lawing the truck. Gm was THE worse company I have ever dealt with. Get rid of it while you can if your motor sounds anything like mine. Its just going to get worse.

If you need a good lemon lawyer in CT shoot me a PM. I'm also a fellow motocross rider!

Very disappointing. iv owned 3 other Silverados before this one, all had well over 200k and were still running great. Really crappy situation because I really like the truck. I'm going to bring it in to the dealership to have them look at it and see what they say, but chances are they'll tell me to wait for GM to come out with a fix, which they wont, itll blow right when my warranty expires and then they'll be happy to fix it. I should've just bought a new Tacoma

Naah. Tundra. Tundra's are not as boring as the Tacomas.. but like all Crapotas, they are still boring..

Boring but bulletproof and reliable so you can actually enjoy life. Plus the Toyotas have the highest resale value on the market.

GM truck owners are going to be left with a giant money pit once the warranty expires.

Bulletproof? No. They have their issues. Plenty of disappointed crapota owners out there. I'm one of them. But they certainly have a better reputation than any of the others out there, that's true.
