2014 Cadillac CTS Problems

What owners report

Complaints about this model year are dominated by rear axle and differential noise — a grinding, whining or roaring sound from the back of the car that owners were most often told required differential replacement. The rest of the sample is a mix: a CUE touchscreen that cracks or freezes, front suspension and control-arm noises, and a handful of no-start or stalling events. Reports cluster well above 50,000 miles, though some issues appear much earlier.

1. 1
   Transmission and drivetrain

   Rear differential noise or failure

   • 77 complaints (53%)
   • median 78,000 mi at 7.3 yrs old (36 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2017–2026

   Owners describe a grinding, whining or roaring sound from the rear of the car that grows louder with speed, sometimes with metal shavings found in the differential fluid. Several report the rear end locking or seizing while driving, and dealers or independent shops typically diagnosed a failed rear differential that needed replacement. Many complain that parts were unavailable or backordered and that repairs were not covered. Mostly reported between roughly 40,000 and 100,000 miles, with a few at higher mileage.

   What to check: Listen for whine or grind from the rear while accelerating and coasting at 30-60 mph, and ask whether the differential fluid has been changed and inspected for metal. Ask for any differential service records.

   “There is a recall for the rear differential. I, along with several other owners have been waiting on parts for several months. Gm does not seem to be taking this seriously. We are also being provided with loaner cars car but it was not one I could accept and as such, risk injury every tube we drive.”

   NHTSA complaint #11352790, filed 2020-09, 55,000 miles

   “The rear differential in my vehicle had to be replaced. Two of the main bearings failed. We noticed a grinding noise from the back as we drove. In august of 2019, I took it to my regular mechanic and he rode in the vehicle with me. He heard and felt the grinding. He recommended that I take it to a reputable transmission mechanic. I took it immediately to bay area transmissions. My vehicle was on the brink of a catastophic failure according to the transmission mechanic. …”

   Recall 14V394000Recall 14V6140001 related service bulletin

   What to check: Ask about any no-start history, battery and starter replacements, and whether the ignition-related recall and chassis module recall were completed for the VIN.

   Electrical system

   CUE touchscreen cracking, freezing or unresponsive

   • 6 complaints (4%)
   • median 64,000 mi at 6.0 yrs old (6 state mileage, few)
   • filed 2018–2020

   Owners report the center touchscreen developing a spider-web crack while the car was parked, or freezing and responding to touches with delay or on its own. When it fails, climate control, phone pairing, navigation and sometimes the backup camera become unusable. Complaints describe dealers calling it a known recurring issue on these screens and quoting an out-of-pocket replacement. Reported from about 37,000 to 105,000 miles, often noticed after the car sat in a parking lot or driveway.

   What to check: Test every screen function — climate, audio, phone pairing, backup camera — and look for hairline cracks or delamination around the screen edges. Ask whether the screen has ever been replaced.

   “While driving, the cue system became inoperable and had a delayed response to touch. The vehicle was being driven on a highway travelling approx 65 MPH. I pulled over to record video of the system not responding. Additionally, there are times when I put the vehicle in reverse and the backup camera doesn't not turn on as it is supposed to.”

   NHTSA complaint #11282449, filed 2019-11, 58,000 miles

   “I have a 2014 Cadillac CTS and the cue was replaced about 4 years ago when it was under warranty. Now the cue screen has cracked on the left side and gone out again. I cannot pair my phone to the car or adjust the temperature from the top or feet area. This is ridiculous. I also see now there are numerous complaints regarding this faulty system. This needs to be recalled and properly fixed.”

   Suspension

   Front suspension and control-arm noise

   • 19 complaints (13%)
   • median 40,000 mi at 4.6 yrs old (14 state mileage)
   • filed 2015–2026

   Complaints describe clunking or hitting noises from the front when turning, and in one case worn lower control-arm and subframe bushings that would not hold alignment. Others report rattling and instability from the rear, and a strut failure at low mileage. Repairs were typically done at the owner's expense or left undiagnosed. Reported from as little as a few thousand miles up to about 90,000 miles.

   1 related service bulletin

   What to check: Drive over uneven pavement and listen for clunks or knocking from the front and rear, and ask whether control-arm bushings, struts or hub bearings have been replaced.

   2 excerpts from owner complaints in NHTSA records

   “Front lower control arm bushing failure of all subframe bushings. To include driver and passenger sides totaling 4 bushing failures. Failures perpetuate excessive movement of the lower control arms. Results: unsolveable misalignment, in extreme situations allowing movement of the wheel camber +/- approximately 1 at speeds exceeding 25mph causing great safety risk.”

   NHTSA complaint #11128594, filed 2018-09, 30,000 miles

   “When I turn the wheels left or right either going forward or backward, there is a hitting noise that feels like the front tires will come out of the accel and this happen while in motion on city streets ,it would be more dangerous if it is on high way”

Buying note. Have a pre-purchase inspection focus on the rear axle and differential, the CUE screen and the front suspension, since those account for most of what owners report on this model year. Ask for service records and confirm open recalls were completed for the specific VIN.
