The primary issue with the vehicle is the failure of the front transmission pump seal (part #24225543) and the torque converter seal ( part #242337534 ) which caused a significant transmission fluid leak. THe original repair of the torque converter seal was done in Jan 2024 by Andrews Cadillac In Mt Juliet Tn. Failure to properly repair the torque converter seal led to internal damage within the transmission, resulting in the need for a full transmission replacement. THe front pump seal was not replaced as recommended by the service repair manual at the time of the torque converter seal replacement. The faulty component is available for inspection upon request. The safety of myself and others was put at risk due to the vehicle's hesitation to accelerate after stopping, a direct consequence of the low transmission fluid. This hesitation causes a sudden loss of power while driving, increasing the likelihood of an accident. THere is a delay and then a hard shift when off , a significant bump when shifting from first to second gear and when I stop it feels like I've been rear ended by another car. The issue has been confirmed by multiple service centers, including Parker Cadillac, ORR Cadillac, and Christian Brothers Automotive, all of which identified the transmission pump seal as the source of the leak and the resulting damage to the transmission. Additionally, Christian Brothers Automotive found that the torque converter seal was also leaking, further contributing to the vehicle's transmission problems. Despite efforts to have GM engineers inspect the vehicle at ORR Cadillac, they declined. However, Christian Brothers Automotive has provided a thorough inspection and diagnostic of the .There were no warning lamps or error codes indicating the issue, as it was a mechanical failure rather than an electronic one. The symptoms became apparent when the vehicle began hesitating after coming to a stop, and a transmission fluid leak was discovered during the inspection​

WHEN TURNING THE STEERING WHEEL IN EITHER DIRECTION, LEFT OR RIGHT, OF THE VEHICLE, THERE IS A LOUD METAL-ON-METAL NOISE. THE VEHICLE HAS BEEN TAKEN TWICE TO MCGUIRE CADILLAC WHERE I WAS TOLD THAT THERE WAS "NO FIX AT THIS TIME." I HAVE CONTACTED CADILLAC HEADQUARTERS NUMEROUS TIMES AND, UNFORTUNATELY, NO ASSISTANCE HAS BEEN GIVEN. ON DECEMBER 30, 2015, WHILE DRIVING 60 MPH ON THE RIGHT LANE OF A HIGHWAY, I SUDDENLY LOST CONTROL OF THE VEHICLE AND THE VEHICLE VEERED ACROSS TO THE LEFT ACROSS THREE LANES ON THE HIGHWAY. THE VEHICLE DID A 360 COMING TO REST FACING ONCOMING TRAFFIC WHERE I HAD NO CONTROL OF THE BRAKE OR GAS PEDALS IN THE VEHICLE. AFTER COMING TO A HALT, I WAS THEN ABLE TO GAIN CONTROL OF THE VEHICLE. IT WAS A VERY SCARY SITUATION.
