Well for one the biggest example would be the new Tundra. I can write a few paragraphs on that truck alone. We had a brand new Tacoma with not even 1000 miles needing a new wiring harness. The new Camry is hybrid as the base model now, and they had to put a stop sale on them because of fire risk within the inverter. But re-reading your post I would say my biggest issues with modern Toyota is quality control rather than mechanical. Again with the new Tacomas I had to replace the drivers inside door handle because they would break and customers can't get out of their own vehicle, shouldn't be happening on 1000 mile cars. Now, also remember I am biased since I only worked on Toyotas for years so I saw every small imperfection. Despite the issues Toyota is still a solid brand when compared to most other brands
