2011 Cadillac CTS Problems

What owners report

Owners of this model year most often write about airbag warnings and non-deployments, rear differential noise, and the engine or electrical system cutting out while driving. Many complaints come from cars with relatively low miles, and several describe symptoms that appeared at highway speed or shortly after buying the vehicle.

1. 1
   Air bags

   Service Air Bag light / airbags not deploying

   • 20 complaints (20%)
   • median 72,741 mi at 7.0 yrs old (16 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2012–2023

   Owners describe a "Service Air Bag" message appearing with no crash, sometimes traced to the passenger presence module or a seat wiring harness, and in other cases side or frontal airbags failing to deploy in a collision. Some say the dealer replaced a sensor or harness and the light returned; others report the cause could not be determined. Several owners note the car had no warning codes before the event. Reported from under 5,000 miles up to about 130,000 miles, with many between roughly 30,000 and 75,000 miles.

   Recall 14V341000Recall 14V394000

   What to check: Ask whether any airbag module, harness or sensor work has been done, and confirm the ignition-key recall and the roll-over-sensor recall were completed for this VIN. Have a shop scan for stored airbag codes before buying.

   2 excerpts from owner complaints in NHTSA records

   “The airbag indicator has come on. I own two Cadillac vehicles and coincidentally the escalade has an airbag recall and, the same indicator light has illuminated on both vehicles. I am concerned that this recall is a potential hazard. We live in florida where it's hot, so we constantly drive in the sun. For the recall to be unresolved and now both indicators for airbags are illuminated I believe that this may be apart of this takata issue. …”

   NHTSA complaint #11269848, filed 2019-10, 129,851 miles

   “On 12-2-19 at 730am eastern time, I was involved in a 55 MPH side impact crash to the right side of the vehicle by a semi truck on interstate 475 north in toledo, ohio, mile marker 10, near holland, ohio. No side impact airbags deployed. Vehicle is in 100% excellent maintained condition. No fault codes. Vehicle structure maintained very well for a highway speed crash, however, I have a concussion from the side impact and no airbag deployment. Car was totalled by the semi truck insurance company that struck me.”

   • 9 complaints (9%)
   • median 38,847 mi at 3.3 yrs old (9 state mileage, few)
   • filed 2011–2019

   Owners report the engine shutting off without warning at speeds from about 25 to 70 mph, sometimes with all power to the dash and steering lost, and restarting only after several attempts or not at all. Others describe a "service stability track, engine power reduced" message followed by a sudden loss of acceleration. Dealers are described as unable to duplicate the problem in some cases. Reported from a few thousand miles up to about 65,000 miles, with many in the 1,700-40,000 mile range.

   2 related service bulletins

   What to check: Ask whether the throttle body, ignition switch recall work and battery/ground connections have been serviced, and note any stored codes or intermittent no-start history on a scan.

   “On 21 feb. While driving approximately 75 MPH, a warning light came on indicating service stability track control, engine power will be reduced. I suddenly lost power and luckily, the 18 wheeler that was behind me swerved to other lane to avoid rear end collision. I immediately put on my hazard indicator and was able to coast to the median. Luckily, I was not killed!. …”

   NHTSA complaint #10689805, filed 2015-02, 61,000 miles

   “Driving on a curvy country road the engine suddenly died, I lost power steering and almost ran off the road. I was able to coast to a stop. I put the car in park and it started immediately. The car does not have an ignition key, only a fob. The engine is 3.6 CTS 4. I drove 2 miles back home and parked the car and will not drive it again until a resolution is obtained for the problem.”

   Transmission and drivetrain

   Rear differential noise or failure

   • 10 complaints (10%)
   • median 61,000 mi at 5.7 yrs old (9 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2010–2020

   Complaints describe a groaning, roaring or thumping noise from the rear of the car, sometimes present from new and sometimes returning after a differential fluid change or a full rear-end replacement. A few owners report binding or labored movement when reversing with the wheels turned sharply. Dealers are described as replacing the differential, and in some cases the noise came back afterward. Reported from near-new mileage up to roughly 150,000 miles, with several cases in the 30,000-65,000 mile range and some repeat failures within about 20,000 miles of a replacement.

   2 related service bulletins

   What to check: Listen for a whine or roar from the rear axle on a test drive, especially while turning at low speed, and ask for service records showing whether the differential fluid or the unit itself has been replaced.

   “I bought my 2011 Cadillac CTS-v brand new on 04-12-11 ,my sealed rear end went out at 33,453 miles which I was out of warranty by 9 days so you guys made me pay $4690 for a 'new rear end that had updated parts that failed and I wouldn't have this problem ever again ..... Well here I am at 54,569 miles and I need another new rear ended replaced me and the dealer both agreed . …”

   NHTSA complaint #11337403, filed 2020-07, 53,000 miles

   “Every time the automatic transmission is put in reverse and the vehicle wheels turned sharply to right or left, such as in backing- out of a tight parking space, the car labors to move backwards and binding noises emanate from differential or rear axle area of the car. This condition lessens and completely disappears as the steering wheel is returned to the straight forward or straight back position. I believe this condition has existed in earlier models of my vehicle and has been the subject of a recall. …”

   Steering

   Power steering assist cuts out

   • 8 complaints (8%)
   • median 24,800 mi at 3.9 yrs old (6 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2012–2020

   Owners describe the steering suddenly becoming very stiff and hard to turn, sometimes at low speed in a turn and sometimes at highway speed, with a "service power steering" message in some cases. One owner was told a seal was leaking and the rack needed attention; another reported the dealer called the feel normal. Mostly reported between about 30,000 and 105,000 miles.

   1 related service bulletin

   What to check: Check for power steering fluid leaks around the rack and ask whether the steering gear or pump has been replaced; test the steering feel at low speed during the test drive.

   2 excerpts from owner complaints in NHTSA records

   “While in reverse, front steering seams to skip. It feels like a 4wd. I took it to an authorized dealer and they told me it was normal. They even showed me a bulletin from GM that explained the problem was normal and to do no repairs. After driving 15,000 miles, it has steadily gotten worse. I took it in again. Again they told me it was normal. While there, they tried to sell me new tires because my rear tires are bald. They said it was from high speed starts. …”

   NHTSA complaint #10448466, filed 2012-02, 500 miles

   “Driving down road and slowed down to veer into left turn lane and power steering failed. Steering became very stiff and very difficult to steer. Managed to get car into left lane and came to a stop. Lucky it was not my wife driving as she would of had great difficulty steering car. Put car in park and wiggled steering wheel back and fourth. Steering took several rotations of steering wheel but came back after 10 seconds or so. Decided to proceeded home. Did not drive again until day I took to dealer. …”

   Exterior lighting

   Headlights and rear lights failing

   • 7 complaints (7%)
   • median 40,500 mi at 7.4 yrs old (7 state mileage, few)
   • filed 2014–2019

   Owners report headlights dimming or cutting out without warning, sometimes repeatedly after bulb replacement, and one owner was told the wiring harness likely melted. Others describe the high-mount brake light failing due to the body control module rather than the lamp, and taillights separating from the body at the top edge. Reported from roughly 20,000 to 80,000 miles, often noted as a gradual dimming over time.

   2 related service bulletins

   What to check: Check all exterior lighting, including the high-mount brake light, and inspect headlight and taillight housings for gaps or melted or repaired wiring.

   An excerpt from owner complaints in NHTSA records

   “High mount brake light quit working. I replaced the light with a new light. I found out the body control module has gone out not the light and will be around $600 to replace. Since then I have noticed a lot of other Cadillac CTS high mount brake lights are out with the same problem.”

   NHTSA complaint #11194171, filed 2019-04, 80,000 miles

Buying note. Look for service records covering airbag system repairs, rear differential work and any steering rack replacement, and verify open recalls were completed for the VIN. A pre-purchase scan for stored airbag, steering and powertrain codes is worthwhile on this model year.
