re: New Tundra already having turbo issues?

MMauler - about working out the bugs and kinks - why aren't things like that caught in testing or pre-production models? All manufacturers seem guilty of letting things issues pass without addressing them. My son-in-law owned the first year of Chevy's Colorado truck, with a 5 cylinder engine. Cylinder head issues were a known problem, and my son-in-law had 2 - 3 replaced under warranty. I had a 2016 F-150 with a 5.0 V-8. The intake manifold had a plastic piece that would stick open, requiring the entire manifold be replaced. In the time I owned the truck, the intake had to be replaced twice. This is (was?) a $1,500 two day repair job when performed out of warranty.

Anyway, there seems to be many issues in which manufacturers would rather repair, than re-engineer and permanently fix, a problem. While I understand that cars and trucks are mechanical devices, and that asking every single part to work without failure for the life of the vehicle is unreasonable, not providing a better part when an issue repeatedly presents itself comes off as negligent.
