What everyone has to keep in mind is when purchasing a new truck for upwards of 60k, and many over 70 or 80, is that one of the first things a new owner is going to do if/when something goes wrong is run to the internet and forums to see who else is having the issue and to complain. If you are not an active member of a forum, buy a new truck and 6 months later everything is going great the chances of that person running to a forum to tell everyone how great it is ...well it's miniscule.
I'm a member of Tacomaworld and a couple of GMC groups. There are problems up and down the forums on both sites, yes, even Toyota.
There is not an absolute leader in reliability in pickups. It's my opinion that Toyota was WAY behind with tech and options in the Tacoma and the Tundra and that is part of the reason why it is considered so reliable. They finally caught up with the redesign of the Tundra and the new Tacoma coming soon ...The Tundra already has some known issues, I would bet the all new Tacoma will be the same. With Ford, GM and Ram to a lesser extent redesigning every few years you have to expect some issues. Toyota made the exact same Tacoma for 18 years with a single drivetrain swap and the Tundra for 14. They better be damn good at putting those trucks together.
