The rear differential is making a howling noise. The CTS V sport was recalled but not the regular CTS. Many other customers have made compliant on different websites. I am hoping to have the recall done so I don’t have to spend money on the car. It will be an expensive fix.

Whining or grinding noise by model year
What owners say
Rear Differential is failing, making a loud grinding, howling, screeching sound. Cadillac has already recalled rear diff on same year CTS-V (some models), but not for this or other CTS models, but finding replacement parts is almost impossible because a LOT of people are having the exact same failure.
2014 CTS with 53,000 miles. Loud whining noise started in rear of vehicle. Went to the shop and was told that the rear differential is bad. Technician stated that this is a known widespread problem with this model Cadillac. He also stated that there are no parts available and has 9 other customers waiting for the manufacturer to supply the part. He is being told by GM that it could be up to 6 months wait for the parts. Why is there not a recall. I hope that nobody gets seriously injured due to the faulty parts!
General Motor's design oversights irreversibly damaged the rear differential carrier of my 2014 Cadillac CTS4 around 75,000 to 80,000 miles. Unfortunately, there is no prior indication of the rear differential carrier assembly leaking fluid or damaging the bearing. Only after the problem occurs, the rear differential assembly starts to make a whining sound that can be heard in the cabin of the vehicle. Unfortunately, the whining sound is a clear indicator that the rear differential assembly is damaged irreversibly. The lack of differential fluid in rear differential carrier assembly can lead to a catastrophic failures. The complete failure of the rear differential assembly would result in internal gears seizing up and locking of the rear wheels. Likewise, there is no prior indicators of when the rear wheels will seize up. On highways speeds, this problem can create dangerous and even life threating conditions to the occupants of the vehicle as well as the other motorists sharing the road.
The contact owns a 2014 Cadillac CTS. The contact stated while driving approximately 10-15 MPH, there was an abnormal whining sound detected coming from the rear axle. The contact called the local dealer and inquired about an estimate. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure however, no further assistance was provided. The approximate failure mileage was 50,000.
Heard a whining noise coming from the back of my vehicle when stepping on the accelorator, took my vehicle in to get a inspection and turns out the roll pins in the rear-axle differential are close to fracturing, increasing the risk of a crash. There is already a recall in this reguard to 2014-15 cadillac cts (v-sport) models but no other cts models get the recall. I have a 2014 cadillac cts (luxury) sedan, hoping there will be a recall for all cts models in regards to the huge safety issue.
2014 cadillac cts awd. Vehicle started hesitating while turning. Which turned into a whine and then grinding from the rear differential. Noise starts at 30 MPH and increases as speed increases. Have seen many cases of cadillac rear differential failing. Issue verified by the dealership february 2021. Now gm has no replacement units or repair parts for this differential. Gm part 84110751
My rear differential sys is making a loud grinning noise, I contacted cadillac customer service 04/28/20, to see if it under recall status and I was advised it was not. I have researched that this is a very common problem for the 2014 cts. I have 98139 on my cadillac and I don't think I should have problems like this. That loud grinning and whining sound is very annoying and embarrassing. I thought it was my brakes at first however I took it to a mechanic and was advised my rear differential system is causing the winning and grinning sound.

- What is wrong
- General Motors LLC (GM) is recalling certain model year 2013-2014 Cadillac ATS vehicles manufactured April 23, 2012, to March 20, 2014, and 2014 Cadillac CTS vehicles manufactured June 10, 2013, to March 20, 2014. In the affected vehicles, the transmission shift cable may detach from either the bracket on the transmission shifter or the bracket on the transmission.
- Risk
- If the transmission shift cable detaches while the vehicle is being driven, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver goes to stop and park the vehicle, despite selecting the 'PARK' position, the transmission may not be in 'PARK.' If the vehicle is not in the 'PARK' position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
- Remedy
- GM will notify owners, and dealers will inspect the vehicles to make sure the cable is properly seated at the transmission and shifter brackets, free of charge. The recall is expected to begin in early August 2014. Owners may contact Cadillac customer service at 1‑800‑458‑8006. GM's number for this recall is 14179.
