The rear differential went out while I was driving.

In about mid November 2021 a grinding noise became noticeable from the rear of my car and quickly became louder. From experience, I thought it was probably bearing failure. The car was parked at that time and has not been driven since. Today is 12/20/21, so the car has been out of service for one and a half months at this point. An ASE certified mechanic inspected the vehicle and found the rear differential to be defective, it was identified as the obvious source of the noise and had metal particles in the fluid. Doing research I found that rear differential failure was common in Cadillac CTS's and a GM safety recall N192279370 had been issued with the bad units being replaced at "no charge". The Cadillac designated model in question is the CTS-V with the 3.6l twin turbo V6 engine. My car is a 2015 CTS with a 4L turbo engine. I haven't found a recall issued on this model and I don't understand why it hasn't been done. I feel that a differential failure in my vehicle would be just as dangerous as that in the designated recall vehicle, it's basically the same car with a different engine. The vehicle was inspected by one mechanic only, but his findings reveal an obvious fault. A review of the incidents with the designated vehicle involved show that very serious safety problem exists which would threaten the driver and passengers if this vehicle was put back in service. I expect that GM must recognize that this safety fault affects a wider range of their vehicles and it has to be included in their recall. I ask NTSHA to intercede.

The cue system is cracking and non responsive to any touch input. I have followed the instructions for resetting the system but this does not correct the lack of response nor the screen cracking.. I cannot control the navigation system, radio, specific climate settings, language of the instrumentation (currently stuck in french). This is not covered now that out of warranty and the dealership wants $2000+ to replace the entire unit with an identical one that will develop the same problem. This is a design defect and these should all be recalled. NY wife is disabled and relied on the navigation system to find directions to locations.

Cue screen begins shaking and touch screen does not work. This screen controls heating, air conditioning, radio, navigation, phone, settings. I had it replaced at 26,053 miles while still under warranty, and at 63,000 miles, out of warranty, it is doing the same thing.

I purchased this car 15mar16 from dublin Cadillac in dublin, ca. The driver side blind spot detection was not working. I took the car back and they confirmed it was not working correctly, but told me there was nothing they could do about it and that "I would just have to live without it". since this is a safety feature, I thought they should have corrected it under warranty. They have refused, so I am bringing this to you attention and requesting help to get it working correctly. I have had two close calls due to this problem. The dealer is dublin Cadillac, 4200 john monego court, dublin, ca.
