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.

During a service appointment, on my 2014 Cadillac CTS, the dealership pointed out that both axle seals on the differential appears to be leaking. On a subsequent inspection conducted on 8/24/2021, by the dealership, it was confirmed that both axle seals were leaking. At the time of the inspection the vehicle had 120,873 miles showing on the odometer. These two reports were the initial indication that the axle seal were leaking. The dealership has maintained the vehicle since I purchased it from them. I checked to see was if there was a Service Bulletin on this issue, but there was none. However, there was a Service Bulletin (Bulletin No. PIP5075A) concerning "Rear Axle Leak From The Vent" on the differential on the 2011-2013 Cadillac CTS and CTS-V. I contend that GM over compensated for the vent leak and now the vent on the differential of the 2014 Cadillac CTS does not release the built up air pressure which is causing the seals to leak. It is only a matter of time when the differential will lock up due to lack of lubricant and cause a serious accident. I contacted GM on this issue, but they do not want to admit there is a problem. However, if you look up complaints on the internet, there are many many people with this issue on Cadillac's CTS and ATS. There needs to be at a minimum a Service Bulletin issued. I would recommend a recall to correct this problem.

I brought my car to my trusted local mechanic, and he informed me that the noise I was hearing from the rear of my car was the differential. He also informed me that it was dangerous because it could lock up, causing my car to go into a skid and lose control. I did some due diligence on the internet and discovered it-??s a common problem, and although it has been recalled on the sub model of the V sport, the standard CTS has not been recalled.

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

- Rochester, NY, USA

Starting around the end of February, my 2014 Cts 3.6 AWD started to have noise from the rear end while driving. The noise becomes louder if I drive faster and the car wobbles. I feel extreme unsafe and have visited individual mechanics, and mechanics told me the issue is from the rear differential. They said they don't have the parts, and cannot fix the problem. Through my research, the rear differential problem seems to be common among the Cts model. However, while there is a recall for the Cts vsport, no actions are taken for other versions of Cts. From NHTSA complaint site, several compliant cases have been filed for the non-sport Cts. There are other cases mentioned across the internet: Https://youtu.be/ucmimohfepq. This problem sould be taken seriously to avoid safety risks. I believe this rear differential issue is a serious safety problem. I would like to 1.get replacement part and service from the manufacturer to fix the rear differential issue on my car and get reimbursement for all costs 2.urge the manufacturer to put the Cts make onto the recall list for safety of other Cts owners.

There have been many, many complaints about the 2014 Cadillac Cts 3rd gen rear differential going out at way to soon. Before the 80K mile mark in alot of these cars. As expensive and rare as this part is, it should not be failing or leaking so soon, as it is the main part that moves the wheels in a rwd car. I did not believe it at first but after my purchase the rear differential went bad at only 75K miles. I replaced it, with a used rear diff that had only 50K miles, 10K miles later, it starts leaking and going bad again. Even used ones are a whopping $1K and up. This part should definitely be investigated at all dealerships nationwide, I assure you that there is an unreasonable amount of records of this part going bad to soon.

Bought this car and after buying it, I heard a vibration. First I thought it was the road and then thought it was the tires. I started checking around for tires when it became very noisy so I called the dealer. He first said it was the power train fluid needed changed but later called and said it was the torque converter. This car has less tha 40,000 miles.

On October 27th, I took my car to the shop for an oil change and inspection. I was told by the mechanic that my rear differential was going out and there were metal shavings in the compartment. The sales rep, nick, said there was not a recall and the repair would be $3300. Through my research that there is a recall for "defective rolling pins in the rear differential that were fatiguing and fracturing and eventually causing the rear end to lock up" but only for the 2014 Cadillac Cts-V not the regular Cts. Since this was a safety issue, I had to rent a car on 11/11 to get to and from work. After conversations not receiving any cooperation from Cadillac corporation, I was referred to GM corporation. They negotiated a discount, reducing the cost for repair from $3300 to $1400. The repair was not completed until 12/1. they reduced the price by another $500 the day I picked up my car. So, I paid $900 for the repair and $517.17 for the car rental (total $1,417.17). Although they significantly reduced the cost of the repair, I still believe this was a safety issue and an expense that should have been covered in the recall. The rear differentials in a Cadillac Cts-V and Cts are the same. The Cts-V has a stronger engine, meaning more torque, which means the rear differential in the normal Cts should last even longer. My 2014 Cadillac only had 70,000 miles; therefore, the rear differential should not have gone out so soon. I would like to be reimbursed for all costs and see this item put on the recall list for the safety and benefit of other Cts owners.

This complaint is regarding an active recall on my Cadillac...manufacturer recall numbern192279370 and NHTSA recall number20V038. I was notified of this recall and in May 2020 that the parts to fix the car were now available. I went to make an appointment for the repair and the parts were no longer available and were on back order. As of this date the parts are still not available. It sounds like this recall could potentially be a serious issue, but GM seems like they are dragging their feet on fixing the problem! it will soon be 5 months since I was notified of the parts supposedly being available but my car is still not repaired. It seems a bit unreasonable to me for this to be taking soooo long to fix a serious flaw in the differential. Is there anything that can be done to speed this process up? thank you for any assistance that you can offer.
