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.

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.

Differential is going bad and it-€™s only got 60k miles on it and if the wheels lock up that is bad. And I can-€™t find the part nowhere.

- Chicago Ridge, IL, USA

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!

The rear differential failing at very low mileage on the 2014 and others models and years using the same part is a very common issue. The CTSV model was recalled and not the cts models. Even though it-€™s the same part but just one single different number in the part number. This is very offsetting being that it-€™s a costly part and requires costly replacement. It almost always can never be repaired but only replaced. Cadillac has recognized that it-€™s an issue but only recalled the CTS vsport models. Even though it-€™s the same exact part. My car isn-€™t able the be driven due to this due to high demand of the part making it very difficult to find. The part number is 84110751.

I have 75,000 miles on a 2014 Cadillac and the rear differential is bad, they have recalled this same differential on the same year of vehicle but only if it was in the turbo model. What's the difference? same part, same thing is wrong.

Rear Carrier Assembly is making grinding noise. Mechanic says that driving car could be life threatening. GM and Cadillac dealership has no parts. So car is useless. The car has 56,000 miles. There should be a recall and remedy for this Model, 2014 Cadillac 3.6L CTS. Especially when the V version of this car already has a recall. GM should be held accountable for this design flaw.

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.

-€¢ Rear Differential is malfunctioning and is making a loud roaring, grinding noise. Is available for inspection. -€¢ Safety concern is no warning lamps notify you of malfunction and if differential goes out while driving wheels can lock up and increase the chance of a crash, And is a danger to passengers as well. -€¢ Called Dealer and was told part was discontinued probably because they know it is a bad part. Was told to rebuild or find a used part from junkyard. 2 independent service centers confirmed differential is malfunctioning. -€¢ No warning lamps to notify you, loud roaring, grinding noise can be heard.

Differential are bad in these cars with only 60,000 miles and and if it goes out, car could lock up causing an accident. Recall has been issued but not for all vehicles. Which there are a lot more vehicles with the issue than that have an recall put in them. 2014 Cadillac CTS RWD 3.6L like mine should be recalled immediately.

I notice the differential was leaking and had to repair it but I am not certain if this will happen again

- Winter Haven, FL, USA

I started to notice pulsation upon braking and replaced my pads and rotors, at the same time switching from winter wheels to summer wheels. The pulsation continued, and then I noticed a rumbling sound from the rear end that has grown increasingly loud over the past three days, and now it is accompanied by wobbling upon braking at speed. An independent shop today diagnosed it as a rapidly failing rear differential. The car has 70,000 miles and no accidents. As I understand it, the CTS-V version of the same vehicle has a recall for failing differentials that are the very same part that's used in these non-V models. The web is full of complaints from other owners of my model who are experiencing this same issue. It is a catastrophic failure part that could cause the rear end of the car to lock up at speed. Please address ASAP, thank you!

The manufacturer was notified and advised the contact to have the failure diagnosed at a dealer. The vehicle was not diagnosed by a dealer nor was a case opened. The contact was referencing the failure to NHTSA Campaign Number: 20V038000 (Power Train).

Rear differential failure at low mileage

- Independence, MO, USA

Rear differential lock up at high speed. Loss of control. Apparently a common problem with Cadillac rear differentials. Most occur under 50,000 miles. Mine had 54,000 miles. Seals fail and differential fluid drains out. Some people have had 3 replacements under warrantee. Cannot find and replacements as they are "back ordered" according to dealerships.
