- Medium severityFrequency: OccasionalToyota Land Cruiser J150Frame and sill corrosion on a chassis-based 4x4Two Russian sources (Auto.ru and Tengrinews) say the Land Cruiser Prado 150 chassis has no factory anti-corrosion protection and starts to rust at 5 to 10 years in salty climates; a Polish owner of a 4.5 D V8 reports the same and also rust on a sill. They are accounts from countries with harsh winters, not data for Spain.
