I bought 2016 new and have 150k and all I have had to do is brakes and replace rear caliper. No issues otherwise. Toyotas are solid!

I have an 07 and it’s been pretty reliable for the most part. My biggest complaint has been the emissions system… it’s hot garbage and the parts to fix it are expensive. That said many people install a plug and play system that bypasses thise parts altogether. It’s not really needed anyway(only runs when it’s under 40 degrees and for first like 10min of starting the vehicle), but if the part is bad it will throw the truck into limp mode. Also, I have a long bed, so the thing is super bumpy on the freeway. You might test drive various roads.
