My air bag light randomly appeared and has been on for at about year now the dealership wants me to pay a ridiculous amount of money for all of these safety hazards including to fix my "airbag sensor" when I have never used the airbags. I am the one and only owner of the car which I purchased directly from the Ed Morse bayview Cadillac dealership. Faulty airbags and or sensors are a huge safety hazard. I need to know my airbags are working correctly as well as the sensors not only for my safety but as well as my child. My car has recently been diagnosed with serious transmission problems which include a vibration at 50 mph shuddering erratically and frequently to the point it is scary to drive. the transmission going out could cause me to get into an accident or be stuck in the road and put into danger which is another safety hazard. …

Transmission drags. When stopping the car jerks bad and sometimes proceeds to accelerate. When at a stop auto start has a hard jerk I reported this problem to Cadillac dealership when I first got the car. They claim they couldn't find an issue. The touch pad goes out frequently.
While arriving at stop lights the caddillac roughly shifts down jolting the whole vehicle. Around 1500 rpms whether its sitting or just passing 1500 rpms the whole vehicle shutters and vibrates aggresively until around 2000 RPM. Rpms jump up and down between 1000 and 3000 rpms
My engine RPM would randomly lock to 4000 rpms while driving, i could rev the car or apply the brakes but it will sit their until it decides to respond. This has happened a few times and mostly down hill and flats. Difficult to replicate. Cooling system has been a plague at around 80k miles i've had to replace a clamp at the back near the water outlet flange which i was quoted $2000 for just the labor alone as the engine would need to be removed.And the water pump failed at around 82000 miles. Also plagued with P06DE "Engine Oil Pressure Control Circuit Stuck On" error code a few times now.
