2003 BUICK LESABRE Steering Problems

The transmission doesn't shift correctly even after it's warmed up it is erratic and rough while connecting the transmission gears and jerks very hard at most times. The power steering is not working correctly and makes it difficult to drive at all with the combined issues I'm very concerned about my and my family safely

On [XXX] original Steering Rack and Pinion was replaced at 138974 miles by established reputable garage with NAPA part which was remanufactured. That part failed [XXX] at 141443 miles. That part failed [XXX] at 145999 miles and was replaced with NAPA part which was remanufactured. That part failed and was replaced at [XXX] at 157999 miles with another NAPA remanufactured part. That part failed about July 2023 and has not been replaced . The repair garage that had been replacing this rack and pinion stated they will no longer replace it since the outcome would be the same. The problem in all instances is that the hydraulic fluid leaks out of the unit through the rack and pinion which in turn affects the steering. The leak starts slowly and eventually increases to the point where the fluid will leak from the unit even when the car is not in use....

WHILE DRIVING ON A 40MPH ROAD, THE ENGINE SPONTANEOUSLY LOST POWER - THE POWER STEERING AND BRAKES ALSO CEASED TO FUNCTION AS A RESULT. THE RADIO AND LIGHTS WERE STILL ON. AFTER GUIDING THE STRICKEN CAR TO A SAFE AREA, I TURNED THE ENGINE BACK ON AND WAS ABLE TO DRIVE AS NORMAL. THE ISSUE REPEATED ROUGHLY A WEEK LATER AT LOWER SPEED WHILE GOING OVER A SPEED-HUMP IN A SHOPPING CENTER PARKING LOT. NOTE: THE ISSUE OCCURRED FOLLOWING THE ADDITION OF APARTMENT AND MAIL KEYS TO THE KEYRING. I SEPARATED THE ADDITIONAL KEYS FROM THE CAR'S KEY FOLLOWING THE SECOND INCIDENT. THE ISSUE HAS NOT REPEATED SINCE. *TR
