Not too many, let me see what I recall...
The exhaust pipe broke down (I took it through a really bad road).
One of the front wheels "popped" out... but that was my fault (used bad spare parts).
The shocks are pretty bad, every time I hit a hole in the street, it sounds really bad...
Paint job was always mediocre... it was burned out by sunlight about two years from purchase...
...But what else can you expect?... it has never been meant to be a luxury car anyway.
Besides, most of the faults I remember were induced by myself, by forcing the engine or by using bad spare parts.
Anyone that complains about the performance hasn't taken it to the edge. I have managed to make a '99 Nissan Sentra eat my dust!!!. I say you can take on anything as good as a 1.8 Renault 19 (carburated engine).
I love the engine sound, it's one of the best I've heard in a small 4 cylinder engine!!!
OK, I admit that it's not the best handling car in Renault's history... it does better in straight line races, where you can take total advantage of the manual 5 speed gearbox.
