Source for the " its a lot higher than that" number?

Most people only join a forum when they have an issue. Last time i checked there was only like 333K people on this board. Out of that number, how many had lifter failures? Between 2019 and March of 2024 there were 2,906,782 Silverado's sold(in the US, NOT INCLUDING GMC SIERRAS) So using those numbers alone, ONLY 11.46% of SILVERADO owners are even on this board, and out of that number, how many have had lifter failures?? SO 1% is a totally plausible number.

Just type in your little browser problem years for GM. Lifter and transmission problems are well represented. Even some class action lawsuits. So it’s not all peachy. I joined the website in 2014 because I hadn’t bought a new GM truck in a while. My ex son in law was a salesman. He gave me a killer deal. For the first time I did no research, didn’t have time. On the way home the V-4 light came on. I’m like what the hell is this? The following Monday I’m getting exhaust on. I’m driving back to my shop and it sounds awful. So I found this website and order a programmer like always. Now I’m learning. So now I start my research. My first trip I’m playing with my programmer. I gained only 1/2 mile per gallon with it on. After finding out all that’s involved with cylinder deactivation I dumped the truck before the warranty is up. It’s a shame. As far as ride and wind noise it was awesome. On E-85 with a tune it ran really well. If you do just a little research the model year I had was one of the worst for GM. More than 1 percent, I think so.

I never said there wasn't an issue, we all know there is. But all makes including Toyota have their issues. But people on here make it sound like every GM truck is going to have lifter issues and that's simply not the case. Like i said before, if every single person on this forum had lifter issues it would only account for 11.46% of total sales, that percentage gets even smaller if we add in the number of Sierras sold to the total. My original count only included Silverados.

Edit:

I went ahead and added those numbers in....

There was 1,340,119 Sierras sold in the same time frame for a total of 4,246,901 Silverados and Sierras. There are 333K members.... So if every single member of this forum had lifter failure, it will only be a 7.84% failure rate. So how many people on this forum have had lifter issues vs those that have not?

Right...no source. That's what I figured.

What's crazy about your numbers is that you correctly point out that the membership of this forum is only a small fraction of total number of trucks sold...but then you go on to assume that every single owner who has had a lifter failure has logged onto the forum here to let us know about it. Strange thinking.

YES the membership here is only a tiny sampling of the total ownership of our trucks...but also, the owners who have posted here about their lifter failures are a similar tiny fraction of the total lifter failures that have occurred.

I don't have a real number for the DFM-equipped trucks but when a class-action suit was being organized for the AFM trucks, the analyst firm that was contracted for data came up with a number around 12%. The DFM trucks are, without question, worse than that. So it's a lot more than 1%.

I have to agree with this. I know my example is small sample size garbage, but to claim that because only "11%" of gm owners use the forum seems like a very half hearted answer to "source for 1%" claim. Also, it seems to dismiss the fact that 5.3's and 6.2's don't make up the entire population of 1500 owners.

That seems like a more reasonable answer just based on the small sample size of people I know IRL that have had the issue. Which is quite a lot.

Where did anyone claim that "Toyota" or whatever didn't have any issues? This seems like a very fanboy response. No offense.

So, 120,000 per million units. That isn't Good. That's Terrible. Literally.

Here's how many trucks GM built since 2010. Millions. They started cylinder deactivation in 2007 I believe

I still say it's less than 1%

Not correct. As shown in that link, I asked YOU for a source. You replied by asking me for a source, without providing one yourself. That's why I replied "no source".

Yeah well. I have to eat my own words now, and crow, and ******. My lifters took a dump yesterday morning. Was at a stop light, gave it gas, heard a loud pop sound, motor started shaking, dash lit up like a xmas tree, and you could hear the lifter(s) clacking.....
