Why are Changan Karvaan users in Pakistan frequently reporting radiator leaks?

: Multiple Karvaan owners across different cities have mentioned radiator leakage even in vehicles under 50,000 km. Is this a fault in the radiator material, welding joints, o r a result of poor road conditions causing vibrations?

Radiator leaks under 50,000 km suggest a design o r material durability issue. Common causes include:

Poor-quality welding at joints

Thin o r low-grade metal used in radiator core

High vibrations from rough roads damaging mounting points
These problems are made worse if the radiator is not mounted securely o r if rubber bushings around it wear out.
