Front Suspension Control Arm problems of the 2005 Volvo S80

We own a beautiful 2005 Volvo S80 t6 top of the line (fully loaded, twin turbos,18" rims, metallic green paint & parking sensors) only 80,300 miles. It's a $46,000 car unfortunately it is not safe for the road and is a hazard to all. It cannot go over speed bumps without shaking everyone inside violently. When driving the car the transmission will slip and stutter at low speeds meaning we cannot merge into traffic! there is also coolant leaking everywhere and spilling to storm drains and sewers list of diagnosed problems: -transmission rebuild neeed (even after paid $150 for transmission software upgrade) -left side window comes up and goes down -check engine light comes and goes -water pump has leak -crankcase ventilation system is clogged. -car cannot hold alignment and veers off -control arms and bushings are bad car has been serviced at a small swede shop & Volvo santa ana frequently and babied. It has new front struts, new belts, new brakes, new rear tires, new cabin filter, etc. Spent more than $2. 5k in the last year already. Volvo corporate denied any assistance and said there were 800 fixes made in the model year 2004. Obviously the car is flawed.

1) events leading up to failure: purchased new Volvo S80 car on 9/3/2005 with 813 miles, drove it home. No information was given on the 813 miles already on the car. The next day there were oil puddles underneath car and oil was all over the passenger side frame underneath the car. The car was taken in for service tues 9/6 morning for oil leaking. The leaking oil pump and seals were replaced. Car was ready and picked up on fri evening 9/9. From talking with the service people the oil pump had been cracked. They said the car had been cleaned of the oil and that there was no more oil leaking. On sat morning 9/10 there was a new oil puddle and oil underneath the passenger side of the car on the frame. Service is closed on the weekend. On mon I was not able to change cars due to work commitments and after driving home from work there was the smell of burning oil. The car was serviced on tues 9/13 for oil leaking. The service people reported that there oil collected in the bottom of the car from the first oil leak. They reported cleaning the car again and doing a lot of test driving to verify that there was no more oil leaking. I received the car back tues afternoon. 2) failure: sat 9/17/2005, I left home with 2 children in the new Volvo S80 car to go shopping. One child was in the passenger front seat and the other in the passenger side back seat. After turning on another side street, the car went to the right and hit a mailbox. The arm (control arm) on the passenger side tire was split broke off. The car had damage from the mailbox to the headlights, hood, and side panel. The passenger side wheel was no longer in the correct position but pushed toward the rear of the car. The car was not drivable and towed by Volvo service to sam swope auto collision center. 3) my insurance company has inspected the damage. The Volvo field tech specialist (fts) inspected the car on thurs 9/22. No information has been released from Volvo.
