Both side mirrors failed. Internal components corroded, one almost fell off when driving, the other later became completely detached. Failed parts that could have caused a major safety issue if they were to fail during operation.

Rear differential. This part will be available after removal. This put me at risk of potentially locking up while driving. According to the dealership, Faulkner Cadillac, "found rear differential bearings damaged, causing noise in the rear end. The Rear Differential will need replaced." There were no warning lights, but there was noise - a new, not normal noise I noticed two weeks prior to the diagnostic procedure by the dealership service department. This is the second rear differential failure. The service writer said there was no sign of leakage.

My vehicle recently started experiencing an issue where the power steering would randomly cut out while I was driving. If I pulled over and shut the car off and then turned it back on the power steering would come back. But sometimes I would have to do this multiple times in a single drive just to keep the power steering on. I know that there is already a recall for this for some 2018 Cadillac ATS and CTS vehicles, but mine was not included in the recall, despite having the same issue. Took it to the dealer for diagnostic and they ended up having to replace the control module for the power steering which cost me around $2000.

The car was parked outside at around 85 degrees. After entering the vehicle and driving with the AC on for a few minutes the CUE screen started to crack on the inside like a spider web. This has already been reported in 11576315 and 11325962. But I can't find any manufacturer communication on these. On the Internet I found that there is a class action lawsuit but only up to the year 2017 and it has already been settled privately. Since the vehicle is out of warranty there is no effort from GM to pay for the replacement. Since the CUE screen is essential for the vehicle operations, i.e. settings, navigation etc. it's a safety issue. On the Internet there are crowds of people complaining …
