ECU, Gearbox bearings, electric windows.
The Car is hideously old fashioned and the bits proton have made to cover up or modify the old Lancer that its based on look cheap and don't last anywhere near as long as the original Mitsubishi made/designed components.
Overall though a decent car, certainly better than the likes of a Lada or old Skoda, FSO, Yugo etc...
This car is actually based on an older style mitsubishi galant, with the only differences being the dash, rear panel and grille. Lancer; where did that come from? GALANT, not the hideous LANCER...
