2014 Cadillac CTS

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.

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 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The 2014-2015 CTS-V Model has a safety recall for the exact same safety problem (differential) my 2014 CTS is experiencing. Why is the V series only included in the recall when other 2014-2015 CTS's have the same issues?

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 contact stated that the rear of the vehicle was very unstable and was vibrating and shaking abnormally. The contact that the rear suspension warning light was illuminated. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The failure mileage was 68,000.

The contact owns a 2014 Cadillac CTS. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormally loud sound. The vehicle was taken to an independent mechanic, who diagnosed that the rear differential needed to be replaced; however, the part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure but did not assist. The failure mileage was approximately 41,000.

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?

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.
