The gears inside the rear-differential of a 2014 CTS Luxury 3.6 liter Cadillac, with 48,000 miles, failed to the point where the whole differential had to be replaced. This defect is extremely dangerous to the owner of the vehicle, as well as others on the road. If the differential fails to the point where the tires lock up, the driver can lose control of the car. There were no warning messages relating to the problem and the problem did not come on gradually. There was a sudden loud grinding noise that came from the rear of the car, while driving, and the car was immediately taken to a Cadillac dealership for inspection. The dealership mechanic/technician determined that the rear differential completely failed and needed to be replaced. (The oil was drained from the differential and there were metal shavings inside the oil.) Upon research on the internet, it was determined that this rear-differential defect is an extensive problem, as other 2014 Cadillac CTS owners are experiencing a similar problem. Cadillac has recalled the 2014 CTS-V for this rear differential defect but has not acknowledged the same problem with the 2014 CTS 3.6 liter (it appears to be the same product/part design.)

The failure mileage was 94,000.

At the moment, the vehicle is releasing a strong order smells like burning oil or gasoline. It’s coming from the rear of the vehicle. You can smell it immediately when you step out and in the car. The rear is making a loud cranking noise and starting to shake. It appears based on the information that it’s a huge possibility it’s my rear differential going out. It posses a threat due to the anticipation of the brakes locking and causing a serious accident to my family or other on the road. Ive taken very good care if the vehicle and done all the required maintenance on the vehicle. Went though GM motors repair shops

2014 CTS 3.6 Differential was replaced in 2019 under manufactures warranty. Les than 50k miles later the differential has gone out again. The dealer will not honor the previous install and wants to charge me close to $6k to fix. This is a known problem with every model because they all have the same differential. GM will only honor the turbo version of the 2014 CTS with the same defective rear end. This can be very dangerous if the rear end locks while driving at any speed. GM is putting my family and others on the road by ignoring a known issue. I am calling out Putnam Cadillac in Berlingame Ca. taking a blind eye to a known issue.
