The biggest issue with with cars made in the last 25 years is the amount of plastic used in both the engine and interior. As plastics age and go through heat/cool cycles the get brittle and easily fail. It’s infuriating to have to dismantle half the engine just to replace a $5 coolant elbow because GM decided to use a plastic one instead of metal.
