Hi the dealer says the car has been overloaded to cause the bushes to pop out that is rubbish the car has only been used as a car mostly 2 people in the front. Only time the back seats have been uses is by a 4 & 5 year olds. Never had any heavy load in the boot. Towed a light caddy 5 foot x 4 foot trailer no more than 300 kgs a few times. Is this a known Hyundia fault?
