Automatic Transmission Torque Converter problem #1

2003 Buick Century has 90,000 miles. Transmission shifts hard on acceleration/deceleration. Obd ii reports dtc of p0742 - torque converter circuit stuck on. Transmission repair shop, and internet search indicate common problem with these type of gm transmissions. Estimate to fix $1900 to $2400. If this is a manufacturing defect, shouldn't gm resolve at no or nominal cost to owner of car?.

Power Train problem #2

The contact owns a 2003 Buick Century. While driving at an unknown speed, the vehicle began to decelerate and jerk violently. The contact stated that it was difficult to maneuver the power steering when making a turn or approaching a traffic light. The vehicle was diagnosed by the dealer more than five times and the rack and pinion was replaced, but the failures persisted. The manufacturer stated that the VIN was excluded from NHTSA campaign number: 09e005000 (steering). The approximate failure mileage was 37,000.

Manual Transmission Lubricant problem #3

The 2003 has a number of issues. 1. The lights turn off at random in the dark. This has happened on numerous occasions. 2. The brakes need to be replaced roughly every 8 months. My mechanic said the Buick Century has brakes that are not adequate for the weight of the car. Costly! 3. Oil system leaks, complete breakdown. $1200 to replace the system. 4. The dials on the temp control come off. I am trading this pos off before it costs me more money!.
