humanGenius, there is a reason why automakers spend 100s of millions of dollars or even over a billion in some cases to develop new models. They don't spend it on lipstick.
Every part is tested under every possible stress condition; especially safety equipment. These are designed to at least stay in perfect working condition for the life of the car; whatever that might be. Once that predetermined time, considered the life of an auto, has elapsed,
everything expires in that car.
And then that car shows up in Pakistan as hardly used, and sold as such.
