2004 Buick Rainier Steering problems

TRANSFER CASE SHIFT MODULE CONTROL MODULE

When backing out of my driveway and turning it seemed like my tires locked up and my car would not move unless I straightened my steering wheel a little. It does the same thing when pulling forward and pulling into a parking space or doing a u-turn. When I touch the gas to make it go the car jumps a little and makes popping noises and my tires squeal a little also. Since this started I've noticed my gas mileage going down. I've heard a few other people having the same issue. *Tr

Purchased vehicle which had 34,000 mile on it. It now has 46,403 and have had to fill the power steering pump up three times. I have detected no leaks. Took to the buick dealer and they said they were unable to find leak. Put some dye in it and said bring it back in a month or so. *Tr

The vehicle's engine has been sputtering, missing and surging since it was purchased. *Nm the vehicle was taken to the dealer but they were unable to find the cause of the problem. The vehicle battery failed. Water leaked through the front driver's side floor. Water also leaked into the vehicle by the hood release lever when raining. The passenger's side fender rattled. Headlight assembly seemed loose. Rack and pinion leaked. *Nm
