Hi, you may think this is a stupid comment but I have noticed of late the amount of people saying the same thing, I would check the height of the ramps you go over and see if they are the legal hight, I have just replaced one on the rear of my wfes car as that had broken and contacted Peugeot UK explained the problem, they reinbursed me with the cost, And before anyone comments the height was checked on the car after replacing the spring the height was the same each side on a level area.
