Предоверявате се на "ии".
Синтезира се "отговор" в случая, до голяма степен базиран на рекламите от производителя, които са в изобилие. (А рекламите в нашето съвремие се градят на манипулации, преувеличения, та до откровени лъжи.) И на това, което се намира, като информация за технологията по принцип.
Ето и по-различен "отговор", пак от ии:
"Toyota models can rust due to design flaws that trap moisture, such as seams in truck beds or behind trim pieces. Inadequate rustproofing on some models, reliance on materials that may rust faster, and specific paint issues can also contribute to corrosion.
Contributing factors to rust
Design issues:
Trapped moisture: Certain designs, like the seam-welded horizontal joint in older Toyota truck beds, can trap debris and moisture, leading to rust.
Inadequate sealing: Some models lack sufficient waterproofing and internal sealing, which can allow moisture to get in and cause internal deterioration.
Trim pieces: The use of trim pieces that puncture the paint surface allows rust to form unseen underneath.
Rubber seals: Rubber seals on the bottom of doors can trap debris and moisture.
Materials:
Some models use recycled steel, which may rust more quickly than other types of steel.
Rustproofing:
Minimal rustproofing on some models, especially compared to other cars, can make them more susceptible to corrosion.
Factory treatments may degrade over time, especially in harsh environments with heavy road salt usage.
Paint problems:
Some models have experienced paint peeling issues, which exposes the metal underneath to the elements."
