general problems of the 2014 Cadillac CTS - part 1

On April 30,2026 I was pulling into a parking space and the gear shifter wouldn't go in to park with my foot the brake and the gear shifter wouldn't go in to park with my foot the brake and the gear shifter wouldn't go in to park . The tow truck driver who finally responded was able to lift the rear of the car up to see what was wrong with my car and I was placing it in the back of the he determined the cable for thre gear shifter was broken.

The contact owns a 2014 Cadillac Cts. The contact was informed of NHTSA campaign number: 20v038000 (power train). The vehicle was taken to a dealer; however, the vehicle was not diagnosed or repaired. The dealer informed the contact that the recall remedy could not be performed because the transmission and axle had failed and required repair and replacement. The vehicle was not repaired. The manufacturer was made aware of the issue. The failure mileage was unknown.

My 2014 Cadillac Cts has been making what sounded like road noise. After another person road in my car that was not in it daily like I was, they told me how loud it really was. After further investigation, my rear differential has gone out at only 80,000 miles. It’s impossible to drive due to the extreme safety concerns for not only myself but other drivers on the turnpikes and highways.

Own a 2014 Cadillac Cts (VIN: [xxx] ) that was serviced under gm recall n192279370 for rear axle differential seizing. On [xxx], the dealership replaced the rear differential carrier assembly and performed the required hydraulic system bleed. At intake, their own multi-point inspection documented no issues with the transmission, radiator, or cooling system. Immediately after the recall repair, my vehicle experienced severe issues: transmission slipping and radiator contamination with transmission fluid. These problems did not exist prior to the recall service. The dealership now claims the damage resulted from “stop leak” in the system and refuses warranty coverage. However, stop leak was not used until after the failure occurred, and only as an emergency measure to get the car home safely. The evidence strongly indicates that the failure resulted from the recall service, possibly from improper reconnection or contamination during the repair. Their refusal to acknowledge responsibility leaves me with significant repair costs for a problem that began directly after their mandated safety recall work. I am requesting NHTSA’s assistance in investigating this case, as the failure appears to be linked to the recall repair and raises concerns of improper procedures during service. Documentation, including service invoices, inspection sheets, and repair notes, are available to support this complaint. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am filing a complaint against wagner Cadillac in tyler, texas, regarding mishandled recall service that resulted in severe damage to my 2014 Cadillac Cts vsport (3. 6 twin-turbo). Timeline of events: wagner Cadillac performed recall #n192279370 (rear differential). At the time, only the differential code was present. Their own multipoint inspection showed no issues with the cooling or transmission systems. Immediately after recall service, my rear axle warning light came on for the first time. Shortly after, the transmission cooler line at the radiator burst, causing coolant and transmission fluid to mix. This led to overheating, hard shifting, and slipping. To limp the car home safely, I used a stop-leak additive only after the breakdown. The magnuson-moss warranty act clearly states warranty coverage cannot be denied unless the additive directly caused the failure, which it did not. The damage had already occurred from the ruptured line. When I returned the vehicle, wagner Cadillac falsely accused me of voiding coverage due to the additive. They then refused to repair my transmission or cooling system, leaving me with a $30,000+ estimate. Why they are responsible: the problems began only after recall work. During service, wagner Cadillac could have: over-pressurized the system during testing. Improperly disturbed or reinstalled transmission cooler lines. Failed to secure or bleed the cooling system. Any of these actions could have caused the rupture. Their refusal to acknowledge this shifts unlawful blame onto me. Additional concerns: instead of helping me, wagner Cadillac attempted to solicit me to sell them my broken car and buy another vehicle from them — both before and after they denied repairs. This is unethical and exploitative. Impact: I paid cash for this car not long ago. I have now lost reliable transportation, lost my job due to lack of mobility, and face financial.

The gear shifter cable on my 2014 Cadillac Cts failed completely and without warning. The vehicle became totally inoperable and could not be shifted into park, neutral, reverse, or drive. There were no dashboard alerts or signs of failure. This matches the exact symptoms described in gm recall no. 21v473000. However, my vehicle was excluded from further action because it had previously received a visual-only inspection during the recall window. No functional testing was performed. Despite being marked as “repaired,” the shifter cable failed exactly as described in the original recall. Gm confirmed that the recall case was closed after a visual inspection per their protocol. But this inspection clearly failed to detect a dangerous mechanical defect. I have now been without a working vehicle for over two weeks, with the earliest dealership appointment not available until the week of July 7 — and a $180 diagnostic fee quoted, with no guarantee of repair coverage. This breakdown could have resulted in a crash or rollaway if it had occurred while driving or parked on an incline. It poses a serious safety risk not just to me but to the public. Vehicles cleared with insufficient inspection should not be excluded from protection. I respectfully request that NHTSA investigate this failure, hold gm accountable for prematurely closed recall cases, and consider requiring them to reopen and expand the campaign to include vins like mine. I am willing to provide photos, documentation, and records as needed. Thank you for your attention and swift consideration.

I just recently purchased my Cadillac. And the rear end is going out! I literally cannot even drive it anywhere because it is about to lock up completely. It will barely go and definitely doesn't want or like to go uphill. I could hardly go 20 miles per hour when I parked it the other night. There has not been an incident yet but if I hadn't parked it, it could've locked up completely when I was going down the highway is what my mechanic friend told me. It was not bad until just the day before it got to this point. It was making a little bit of a humming noise which I thought was just a wheel bearing the other night because that's exactly what it sounded like. But, the night I parked it it had started making like a loud thumping noise when I would try to accelerate. The more I would accelerate the louder the noise and it just didn't want to go. So, I parked it and that's where it's been since. So, I got online to look and see if there were any recalls for this issue. I find that there is a recall for the 2014 Cts-v for the rear end. I think it's not only the Cts-v models I think it's the regular Cts's as well. Can you check into this for me because I literally just bought this car and haven't even gotten my license plate yet and now I can't even do that or go anywhere for that matter. I am a business owner and I rely on my vehicle and I can't even get to work to open my store right now,. I would greatly appreciate it if you could check into if this recall shouldn't be extended to the regular Cts models as well. Thanks and have a great day.

The gears inside the rear-differential of a 2014 Cts luxury 3. 6 liter Cadillac, with 48,000 miles, failed to the point where the whole differential had to be replaced. This defect is extremely dangerous to the owner of the vehicle, as well as others on the road. If the differential fails to the point where the tires lock up, the driver can lose control of the car. There were no warning messages relating to the problem and the problem did not come on gradually. There was a sudden loud grinding noise that came from the rear of the car, while driving, and the car was immediately taken to a Cadillac dealership for inspection. The dealership mechanic/technician determined that the rear differential completely failed and needed to be replaced. (the oil was drained from the differential and there were metal shavings inside the oil. ) upon research on the internet, it was determined that this rear-differential defect is an extensive problem, as other 2014 Cadillac Cts owners are experiencing a similar problem. Cadillac has recalled the 2014 Cts-v for this rear differential defect but has not acknowledged the same problem with the 2014 Cts 3. 6 liter (it appears to be the same product/part design. ).

My car was unsafe to drive. It would not shift into drive. I had it towed to a mechanic who diagnosed the problem. I was informed the differential was the problem. I could not drive my car until the repair was done. No one had the differential part in the USA. My car is 2014 Cts with only 66,000 miles. Can I be reimbursed for this repair?.

The contact owns a 2014 Cadillac Cts. The contact stated that while driving at 40 mph, he heard a loud, abnormal scraping sound emanating from the rear of the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the rear axle differential assembly. The vehicle was not repaired. After investigating the failure, the contact related it to NHTSA campaign number 20v038000 (power train), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 94,000.

At the moment, the vehicle is releasing a strong order smells like burning oil or gasoline. It’s coming from the rear of the vehicle. You can smell it immediately when you step out and in the car. The rear is making a loud cranking noise and starting to shake. It appears based on the information that it’s a huge possibility it’s my rear differential going out. It posses a threat due to the anticipation of the brakes locking and causing a serious accident to my family or other on the road. Ive taken very good care if the vehicle and done all the required maintenance on the vehicle. Went though gm motors repair shops.

2014 Cts 3. 6 differential was replaced in 2019 under manufactures warranty. Les than 50k miles later the differential has gone out again. The dealer will not honor the previous install and wants to charge me close to $6k to fix. This is a known problem with every model because they all have the same differential. Gm will only honor the turbo version of the 2014 Cts with the same defective rear end. This can be very dangerous if the rear end locks while driving at any speed. Gm is putting my family and others on the road by ignoring a known issue. I am calling out putnam Cadillac in berlingame CA. Taking a blind eye to a known issue.

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.

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 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 .

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.

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 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!.

Rear differential has gone bad. Hundreds, if not thousands of these vehicles have had this issue. Nothing is being done! it’s a shame that us Cts owners are stuck with these problems.

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.

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 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 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!.

Load roaring in back of car sounds like going snap in half. Upon checking the rear differential loud noise.

2014 Cadillac Cts rear differential with 55,000 miles started to make a wobbling noise going past 10 mph. Went to third party mechanic and was shown metal shavings coming from rear end.

I have been told my car needs a front and rear differential. I have heard a low rumbling in the car for some time which I have now been told that sound was the differential breaking down. My car has been at dealership for 2 months now.

The contact owns a 2014 Cadillac Cts. The contact stated that upon starting the vehicle and depressing the accelerator pedal, a metal noise was heard. The contact stated that no warning lights were illuminated. The vehicle was taken to an independent mechanic where the rear brakes were replaced however, the contact was informed that the failure was the rear differential axle. The vehicle was not repaired. 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). The manufacturer informed the contact that only the sports version was included in the recall due to the plant of manufacture. The approximate failure mileage was 92,000.

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.

On 8/24/2021 approx 9:45am I returned home from the market as I was parking my vehicle (backing into a parking space) ishift my vehicle control to the rear position and it lock up it was stuck and would not release I was shocked and upset because the front of my vehicle was still in the way of passing vehicle so I tuned my front wheels in as much as I could but that was all I could do I had to keep my foot on the breaks so that my vehicle would not roll back and slam into the truck behind me , I call the dealership fc kerbeck 100 route 73 north palmyra n. J I told them what happened and that I was upset and did not know what to do I still had my foot on the breaks because I did'nt know if it was safe to turn off my vehicle or what after I was disconnected I called back and I was informed on how to safley shut down my vehicle . My vehicle had to be towed to the dealership I found a recall on the issue from general motors June 2014 saying that the driver may not be able to shift the transmission in and out of gear due to the shift cable not begin secured and that it could slip out of the brackets and the driver will not be able to stop the vehicle from rolling resulting in a ccident when I mention this to the dealership they claim that they never had any recalls on thid saftey issue I purchase my vehicle in 2017 so they were well aware that this could be a saftey issue some where down the line but they failed to make sure that the consumer was aware of this issue that they could have better control if something like this should happen I was so up set and shock that this had happen my gears were lock down I could not at that time move my vehicle. My is this information not made available to the consumer when they buy these cars then a few years later when it does ealership blows you off and act as if you are crazy this is a saftey issue that could cause your life.

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.
