Nobody likes it when their new truck breaks down. And, some even think that because they spent more for a higher trim they should have a more reliable truck. The truth is, the opposite is true. I'll explain why.
GM is currently selling between 625,000 to 650,000 Silverados per year in the US and Canada, 90% of which are sold in the US. The same can be said with GMC's Sierra at 285,000 to 305,000. This doesn't account for sales in Mexico, and we should account for those sales because they are often the same truck, and many of the trucks in the US and Canada were made at GM's Silao plant. So, let's just make it an even 1 million trucks per year to keep the math simple.
Now, let's talk about estimated or planned for vehicle problems. The automotive industry average, utilizing Six Sigma, is projected at 1 per 1 million vehicles. Does that mean only car per year will experience a part failure? No. Why? We haven't taking into consideration the number of parts a typical vehicle has. After all, we're talking about parts failures, not vehicle failures. A vehicle doesn't really fail. Only the parts it's made of do.
According to Toyota, because that's the only place I was able to find this info, a typical vehicle is made of 28,000 to 30,000 parts. Let's assume lower trim levels have fewer parts, because they do. Is the difference as big as 2,000 parts? Likely, not. However, this is for demonstrative purposes only.
Since we're talking about parts failures, and the math is simple, we can assume a new vehicle failure rate of 28,000 to 30,000 per 1,000,000 made. Reduced, that's 2.8 to 3 per 100 vehicles.
Therefore, before complaining about your broken jalopy, realize "stuff" happens and you're just one of the unlucky ones this time around. And, if you had a lower trim level the odds of the situation having happened to you would be slightly lower. With that said, sometimes it pays to have the "nicer" and more expensive vehicle. Just look at how GM replaced all valve springs on the 6.2, but not the 5.3 in the valve spring TSB last year. But, you wouldn't have a V8 with a lesser trim level, would you? Therefore, you wouldn't have had to worry about that problem.
I wrote this because I noticed a bunch of people complaining that they spent $60k to $70k on a new truck and are dealing with a problem. I spent a lot of money, too, on a loaded Trail Boss LT with the 6.2 and a bunch of accessories, but that doesn't mean I'm entitled to preferential treatment.
