2014 Cadillac Cts

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.
