Cadillac XTS Limo 2019 — Reported problems

currently experiencing transmission shuddering — likely due to a torque converter issue. This was confirmed by an experienced mechanic at the dealership of Cadillac. After doing deep research I’ve learned is documented in Technical Service Bulletins such as TSB 18-NA-355 and 19-NA-121. The shuddering has caused the vehicle to slow down or speed up when at cruising speeds. There were no warning lights nor messages, but I've started to experience the issue/symptoms for about a month now. Which came out of nowhere. Recently, I replaced the transmission cooler line and performed a drain and fill, but the shudder continues.

The passenger present module in seat isn’t working with air bag. Per Cadillac passenger seat module is inside the seat and needs replaced.

The tire tech at Walmart was attempting to remove the tire when the side wall just blew out on my Yokohama 245 /40 20 tire.

BRAKES FAILED TO COMPLETELY STOP THE VEHICLE ONCE WHEN BACKING OUT OF A PARKING SPOT AND AGAIN WHEN PULLING INTO A PARKING SPOT

THE BACKUP CAMERA GUIDE LINES CAN BARELY BE SEEN AND IN ANY SUN LIGHT CANNOT BE SEEN AT ALL. AT NIGHT , ALL YOU CAN SEE IS WHAT LOOKS LIKE SNOW. CADILLAC SAYS IT IS A SOFTWARE PROBLEM AND THERE IS NO FIX. THIS IS A SAFETY ISSUE AND NEED TO BE ADDRESSED THERE ARE NUMEROUS COMPLAINTS ABOUT THIS AND CADILLAC REFUSES TO FIX IT
