2005 CADILLAC SRX Power Train Problems

When I start the car and place it into reverse (from its parking spot) and let it idle backwards about 12-18 ft, it abruptly comes to a halt and makes a hard thump noise. If I then shift it into drive and allow it to idle forward, it will barely idle upto about 6-8 feet. I am hearing a plethora of different things and have not been able to drive it since October, 2025. I need help, please.

'TAKATA RECALL' WHEN I WAS DRIVING MY DASH, STEREO AND LIGHTS STARTED TO FLICKER AND ALL THE ELECTRICAL COMPONENTS WERE NOT WORKING. THEN. I TRIED CHANGING LANES ON THE INTERSTATE TO EXIT BUT LOST POWER STEERING. IT WAS VERY DANGEROUS AT THOSE HIGH SPEED!. I WAS ABLE TO PULL OFF BEFORE MY CAR COMPLETELY DIED.. IT TOOK A WHILE FOR IT TO TURN BACK ON BUT ONCE IT DID THE CAR WAS NOT WORKING PROPERLY, SUCH AS THE TEMP AND GAS GAUGE, TRACTION CONTROL WAS NOT WORKING AND LIGHT WAS LIT ON DASH. POWER STEERING WASN'T WORKING, AND THE TRANSMISSION WAS SHIFTING WEIRD. I TOOK IT IN TO THE GM DEALERSHIP AND WAS TOLD IT WAS THE 'ECM THAT WENT BAD' AND IT WASN'T COMMUNICATING WITH THE REST OF THE VEHICLE PROPERLY. IT WAS ABOUT 900$ IN TOTAL WITH THE TOWING AND 'DIAGNOSE AND FIX'. IT WAS FIXED BUT EXACTLY...
