general problems of the 2015 Cadillac CTS

The primary issue with the vehicle is the failure of the front transmission pump seal (part #24225543) and the torque converter seal ( part #242337534 ) which caused a significant transmission fluid leak. The original repair of the torque converter seal was done in Jan 2024 by andrews Cadillac in mt juliet TN. Failure to properly repair the torque converter seal led to internal damage within the transmission, resulting in the need for a full transmission replacement. The front pump seal was not replaced as recommended by the service repair manual at the time of the torque converter seal replacement. The faulty component is available for inspection upon request. The safety of myself and others was put at risk due to the vehicle's hesitation to accelerate after stopping, a direct consequence of the low transmission fluid. This hesitation causes a sudden loss of power while driving, increasing the likelihood of an accident. There is a delay and then a hard shift when off , a significant bump when shifting from first to second gear and when I stop it feels like I've been rear ended by another car. The issue has been confirmed by multiple service centers, including parker Cadillac, orr Cadillac, and christian brothers automotive, all of which identified the transmission pump seal as the source of the leak and the resulting damage to the transmission. Additionally, christian brothers automotive found that the torque converter seal was also leaking, further contributing to the vehicle's transmission problems. Despite efforts to have gm engineers inspect the vehicle at orr Cadillac, they declined. However, christian brothers automotive has provided a thorough inspection and diagnostic of the . There were no warning lamps or error codes indicating the issue, as it was a mechanical failure rather than an electronic one. The symptoms became apparent when the vehicle began hesitating after coming to a stop, and a transmission fluid leak was discovered during the inspection?.

My rear differential gear is failing on my 2015 Cadillac Cts luxury 2. 0t. I just reached approx 69,000 miles upon returning from an approx 2,200 mile trip to the east coast from texas. I noticed a whine like noise after my drive back to texas that seemed to get louder and louder coming from the rear of the vehicle. I took my vehicle to firestone for inspection and it was confirmed the rear differential was failing. I was also advised the the seal were leaking as noted in the attached report. I was shown the drain plug which had an abundance of metal shavings present to confirm. The fluid was replaced and I was advised to follow up ASAP. Upon researching the issue I discovered this is a common issue confirmed on the Cadillac forums. This issue could’ve left me stranded or worse, caused an accident as I was traveling around the christmas and the new year to visit family during peak travel times. There were no warning signs or indications via my vehicle warning systems nor was there any contact from my Cadillac dealer or gm representatives. My vehicle is currently available for inspection as the issue has not been resolved.

Was simply driving my normally and out of no where there was a loud pop and driving the car all I heard was a loud grinding noise as I stepped on the gas, and the car would not shift into reverse. No lights or warnings had ever popped up into the dash. Also very strong burning and metal smell came from the car. I have taken the car to an independent repair shop and was determined the rear differential has gone bad. Apparently many other people with similar year vehicles have had the same issues with this make and model of car, to add on another car like mines came into the same shop with the same problem.

The vacuum pump failed and caused catastrophic engine failure. The vacuum pump was constructed with substandard design and the composition of the parts within the vacuum pumps internal components. The vacuum pump is an integral part of the emissions system, the braking system and the engine. This is not an isolated incident as the replacement vacuum pump, even if replaced, will fail again. The pump should have been designed with a shear pin so the engine camshaft would not have been destroyed.

2015 Cadillac Cts luxury, 81k miles, rear differential has metal chunks in its fluid and makes load roaring sound. Dealership mecahnics said that the differential dailing that early is a known issue, and if it had progressed rhe differential would have seized up and the rear tires would have locked up. No parts available anywhere for differential replacement or overhaul.

The recall that was done on the 2014-2015 Cts-v should have been a recall on all models of Cts because all of the models in the timeframe received the dsame flawed rear differential. My 2015 Cts luxury has only 80k miles on it and the differential has chunks of metal in its oil. It is the exactaame differential as is in the Cts-v. At any time my rear end will lock up once the dofferential fully eats itself. It is an extreme saftey hazard for anyone driving any type of Cts from 2014-2015.

The rear differential started making a loud whining noise around 53,000 miles. It then turned into a grinding noise. I had it checked by a mechanic and he confirmed it was rear differential that needed replacing. He recommended not driving the vehicle since the differential could completely fail and cause an accident. Not having any mechanical experience, the noise was the only indication of a problem. No warning lights or sensor faults.

I was almost involved in an accident on the highway last night, either the transmission or the real axles broke as I was driving 70 mph. Never informed of any recall and I want answers, as it could have been a horrible accident. The car was towed to my home last night. This occurred in battle creek michigan on m66 south.

The contact owns a 2015 Cadillac Cts. The contact received notification of NHTSA campaign number: 20v038000 (power train) however, the part to do the recall repair was not available. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The vehicle was taken to barkley Buick GMC Cadillac, inc, (3575 skyland blvd e, tuscaloosa, al 35405), where the vehicle was rejected to be serviced due to parts not being available for the repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Part distribution disconnect.

Engine sounds like a truck, while driving. Just purchased the vehicle. 30,000 miles on odometer.

This vehicle is the subject of a safety recall issued in Jan. The dealer ordered repair parts on may 11. No answer from Cadillac customer service to inquire about parts availability. What is considered "reasonable time" when addressing a safety recall?.

When idling or when you cold start the car it tends to have a slight shake/tremble feel all throughout the car even passengers felt it also when accelerating slowly and you hit 15 mph car tends to shift hard into 2nd gear.

The vehicle accelerated on its own when it was in park, with the emergency brake engaged, and the engine was turned off. Home security camera captured the entire incident on film. Would be happy to provide the NHTSA with the footage.
