Wiring problems of the 2005 Volvo S60

Headlight wiring and connector burned causing light to go out. The dealer replaced the wiring and connector according to a TSB issued by Volvo. Dealer stated that they had repaired several Volvos with this problem. Although the dealer said this was a safety issue and Volvo issued a TSB and provided a repair kit for repairs Volvo does not consider this a safety issue. Thankfully, only one light burned out at the time otherwise I would have crashed at 70 mph. Dealer said both headlight wiring cables and connectors were burnt and they replaced both. I reported this safety issue to tennessee and kentucky consumer protection division. This one light went out on several occasions before I took the car to the dealer and discovered the safety problem. Repairs made at my cost.

Picked up my brand new 2005 (4 miles on odometer) Volvo S60 on June 9 at dealer. While driving to work the next am, and with 37 miles on the odometer, I approached an intersection. I braked normally and came to a stop. Without warning, the engine raced and the car drove into the intersection. My foot was still on the brake. I narrowly missed an on coming vehicle. I regained control and got the vehicle off the road. The car seemed to operate normally and I tried several stops and starts without problem. I continued towards work and about 5 miles later the same thing happened at another intersection. Without warning the engine raced (tach shot up) and the car took off on its own. I contacted Volvo and had the car towed away. Volvo later told me the main engine computer registered a fault code caused by a "loose wire". I asked for details and the fault code number but Volvo did not respond. The dealer claimed they fixed the problem. I request your help to resolve this dangerous situation. This car may be defective or there may be a systemic design or manufacture defect that endagers Volvo drivers. I am reminded of the Audi 5000 problem. My problem sounds the same.
