2014 Cadillac CTS power train problems

“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.”

“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.”

“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.”

“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…”

“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,…”

“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.
