First, the car rear end went out. Essentially, as previous poster mentioned it is a clunking noise that is heard when going over any significant bump (even small). The car is unable to be driven in this condition. Second, this problem appears to be frequent because we tried to resolve the issue to find out that the part is on back order until SEPTEMBER!!!! Keep in mind of the date of this complaint, it is near the end of August. When speaking to numerous service departments the part was made out of aluminum and should be made of steel to support the suspension. Both parts need to be replaced (right and left side). Due to the back order issue we will not be purchasing another Chrysler product. It is bad enough that the repair is over $500 due to poor engineering but that customers have to wait months to have the car fixed.

right rear spring seat aluminum casting cracked some time ago, and today it basically failed. The macpherson strut/shock absorber is attached to this and it finally gave way, causing a clunking noise in addition to the undetermined squeaking probably due to the crack, which had been especially noticeable in cold weather, since the thing was virtually new. I will be adding a separate complaint about the left rear casting, which is also cracked. It is cracked in a different location, very near to the end of the coils on the spring. This car/thing has never been in an accident, or loaded heavy, and has 52000 one owner miles and could be cleaned up to as new appearance. The spring seat does show evidence of corrosion, but I do not think it cracked recently, as there is corrosion in the crack too.
