Keystone equipment problems

Owners have filed 194 complaints with NHTSA about the equipment on Keystone vehicles — 17% of everything reported about the brand, across 29 models. The model that accounts for most of them is the Keystone Montana, worst in 2022.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
