2014 Cadillac CTS-V power train problems

“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…”

“The contact owns a 2014 Cadillac CTS. The contact stated that while driving 60 MPH, the contact heard an extremely loud bang, after which the vehicle lost motive power. The contact was able to pull to the shoulder of the roadway and observed smoke coming from the rear axle. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the rear axle differential. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 20V038000 (Power Train); however, the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 170,000.”

“The contact owns a 2014 Cadillac CTS A. The contact stated while driving at approximately 45 MPH she heard an abnormal sound from the rear of the vehicle. The contact stated that it sounded like an amplified road noise. Additionally, the contact stated that there was an intermittent sharp jarring of the vehicle. The contact stated that the vehicle was downshifting to a lower gear independently. The contact stated no warning light was illuminated. The contact had taken the vehicle to an independent mechanic who had diagnosed and determined that the differential was cracked and needed to be replaced. The vehicle was not repaired. The contact had researched online and related the failure to NHTSA Campaign Number: 20V038000 (Power Train). The manufacturer was informed of the failure. The failure mileage was approximately 70,000.”

“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…”

“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 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.”
