Problems with 2000 Buick Regal STRUCTURE

Vehicle interior lighting does not work in park, drive or when lights turned on, cluster, gear indicator, climate display, radio lighting does not work at all, when driving at night & windows fog up i have a hard time finding the temp. buttons while seeing safely out windshield. my son pulled out cluster, noticed missing resistors are the cause. driver side leather heated seat gets too hot when switched on, fear it could lead to fire. rear strut snapped from rust/age. son replaced both rear struts, noticed the strut to frame was rusting out where the welds have been made & was not supporting the vehicles weight properly. if these give out, the rear of the car will drop & loose control of vehicle, possibly puncturing the fuel tank causing leak/fire while steering while is parked or in motion, moving steering wheel 9 to 3 o'clock position is a very loud thud. headlight combo switch has failed resulting of losing headlights, interior lights. leaks oil, puddles of oil near plenum & top of motor. its always leaked since owning it. fuel leak inside of engine bay. my son has recently discovered a fuel leak once the motor is shut off. it appears it is the back fuel rail return line quick disconnect fitting that is leaking gas once the motor is shut off, realized the problem when i shut my car off, 5 mins later i started it & could smell gasoline from the heat vents. shut it off. opened hood, strong order of gas present. removed plastic top engine cover & a very strong smell present. traced the fuel lines & found gasoline dripping out of the rear fuel rail onto the motor. son is replacing the o rings in the quick connect to correct the problem. after googling this is a common problem on w-bodys & has caused the vehicles to start a fire but has not been recalled. can provide pictures taken of the leak if contacted

I was driving around a drivethru at kfc and the car immediately began to accelerate. the car began to speed up and steering wheel locked causing my vehicle to crash into the side of the building and damage the gas line. prior to the accident, i saw a recall on the news about the removal of the keys out of the ignition and noticed my vehicle was also able to remove the keys while the car still ran with a red security light. it was 8:30am and there was no other cars involved and i was not using the drivethru, i was just driving up to the door to see what time the establishment opened. *tr

While driving 20 mph the steering failed. as a result, the vehicle crashed into a snow bank. *ak the consumer experienced two crashes due to the brakes and the steering locking. the consumer had taken the vehicle to the dealer on three occasions for the steering problem but the locking continued. the dash lights would come on (gas gauge and oil light), the vehicle pulled to the right and the trunk would fly open while the vehicle was in motion. *sc *jb

Trunk leaks,floor board passenger side fills with water. gives false tire pressure reading warning,dual climate control was inoperable
