1 Differential Unit problem

Failure Date: 02/05/2021

Check engine light came on 2. 5. 21. Took it to the dealer and it needed a hose and sensor which was fixed. On the multipoint inspection,it was noted that there is a safety issue. The rear differential was leaking which can cause the tires to seize while driving. The car only has 63k miles on it. It is a 2013 Cadillac Ats turbo. The manufacturer's warranty expired and they will not cover the replacement. However, I did find a recall on the cts model. I also see a large amount of complaints on the Ats model, as well. The dealer quoted me $5k to replace the differential with only a 1 year warranty. I believe this is a result of poor quality and craftmanship and that there should be a recall on the Ats models, as well. The fact that they only offer a 1 year warranty is also concerning. This would reflect they know of the issue, and will only cover it for the shortest amount possible.

2 Differential Unit problem

2013 Ats awd 3. 6 . Vehicle started making a high pitch whining sound. Vehicle only has 100,203 miles (mostly highway miles) and under 5 years and rear end differential failed dealer estimated cost $3500 because warrantee ended at 5 years or 70,000. Is this related to poor welds previous reported?.

Improper rear differential ring gear weld. There is a gap that is not properly sealed on rear differential housing that causes fluids to leak.
