Trunk lock got stuck several times, due to improper plastic molding. Dealer could not fix it on several attempts, even with replacing a new lock. A little carving of plastic finally helped.
Rubber covering around the windshield installed incorrectly, it became loose in one of the corners, no leaking though, just looks ugly.
One of the keys' immobilizer chip got broken, had to request another key, that took ages to arrive. Dealer was totally incompetent, when programming the new key into the immobilizer system.
Alarm system locked my family out of the car for 2 hours in a shopping mall parking lot. Had to call Renault Assistance. I ordered a Renault alarm system, when bought the car, and during this incident it turned out, that it was one installed by the dealer.
Behaves a bit unstable on the motorway in light bends over speeds of 130 km/h. Feels like it wants to spin around its rear, especially on wet roads (changing tires doesn't help). This might be due to the large trunk, that shifted the car's balance to the rear.
Very poor warranty period of 1 year.
