It could be argued that by increasing the tow rating to a number most customers will never use actually increases the reliability of the truck while towing at the lesser numbers that most people do need. If you think about how to make something more reliable, the first thing that comes to my mind is make it stronger.
My last truck was a pre Emissions 2007 Duramax. My new truck is a 2019 Duramax with DEF emissions. The tow ratings have increased. I believe the frame is more substantial as well.
However the complexity has also increased. There are more electronics
than my prior truck.
While I have lots of faith in my new truck, it is more complicated than the old one. In short there is more to go wrong with it
While my new truck is more capable I don't know that it is more reliable.
Increased ability does not automatically equate to increased reliability. I purchased my 2007 because it was a pre emissions truck.
I deliberately avoided the DPF era trucks that had higher ratings, but suffered from poor MPG's and other issues. The DPF era is a good example of more capability but less reliability.
Fast forward now to the DEF era and the trucks are reliable and more capable. But the big 3 went through a learning curve to get there.
Will this next era of 10 speed trannies and insane power come with a learning curve?
Only time will tell but increased tow ratings is not a magical cure all for reliability issues.
