2015 Cadillac ATS Complaint Log

Fuel and/or combustion problem leading to excessive emissions at unpredictable times. I mean so much smoke suddenly comes out that the driver behind can't see, and it seems the car may be on fire.

The contact owns a 2015 Cadillac ATS equipped with Firestone Tires, Tire Line: Fire Hawk A5V2, Tire Size: 225/45/R18, DOT Number: 17X4F9J46. The contact stated that while driving 25 MPH in rain, the vehicle hydroplaned. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The tire failure mileage was approximately 1,000. The vehicle failure mileage was approximately 74,000.

I bought my car from a dealership. Owned it for 2yrs 2mo. 107k miles First issue came up after 3-4 months. Faulty power steering. Took it to service at a dealership they said I would need my wire harness assembly replaced as well as a steering gear. Problem still persists. Also one of the mechanics there showed me that the previous owner glued harness connector components together which is why I started seeing issues that weren't there before. Now today three new warning/service lights: abs, brake warning and traction control lights. I think it is the battery but I haven't tested it. Someone online with the same issue said he had to replace the electronic brake control module. So this issue has not been diagnosed. As a result of the traction control malfunctioning suddenly I spun out on the highway in slippery conditions but did not collide with anything. Both issues are available for inspection. More information can be found on the quote in the attatchment.

The white pearl paint is chippng off everywhere. It started aat the drivers door directly under the rear view mirror. The underside of the trunk deck lid is completely paint free at this point. There are bubbles eroding on the drivers side rear fender area. When a paint meter was used to check the thickneess of the paint - it was disagnosed at a "1'", WHICH IS THE THINNEST possible number on the paint meter. I would like to demand that these parts of my PRISTINE car be repainted at no cost to myself.

The CUE SYSTEM not totally working, and panel plastic is all spider web looking. I view this as a very bad problem( it won’t go to settings), no radio, can’t set the clock Not sure on all the problems as I can’t get to it to find out.

We have owned the 2015 ATS Cadillac since August 31, 2016 . The rear glass is blurry when looking back from the front seat. We replaced the rear view mirror thought that was the problem but didn’t correct. I checked on the windshield glass. I took these number off the rear glass. GM DOT-376 AS2 M2H3 Trans 70 o/o Min. E6 43R-008011 AGC Automotive 30 B A006450 Tempered GS.I have a picture showing the above Info. Taken from the rear glass…..

I received a warning message : Right low beam light failure. I took the car to the deal and was quoted a price of $900.00 to replace the light. This is a safety issue and should not cost that much to replace a light. Searching the web, that is an average price for this type of repair???

The cue system screen has become unresponsive due to separation of the glue the system is pretty much the heart of the car everything electrical is controlled thre that screen along with the back up camera

See attached document for complaint

My rear differential completely stopped on the freeway, not moving and saying over 100 mph and my car was barely rolling I am extremely lucky that I did not get rear ended because I was very close to that happening, a few cars had swerved to not crash. Luckily I was able to push my car to the exit and get off of the freeway to wait for the flatbed to pick me up. It is available to be inspected it’s just parked until I can get it fixed, the part is $1800 and I have not been able to afford it. I had a mechanic come and look at it and I was told what part it is. There was absolutely no warning lights for this issue.

I NOTICED A ROARING NOISE WHILE DRIVING THE VEHICLE SEVERAL MONTHS BEFORE TAKING IT IN TO THE DEALER I WENT TO BARKLEY CADILLAC GMC IN TUSCALOOSA ALABAMA AND WAS TOLD THAT THE REAR END HAD A PROBLEM AND NEEDED TO BE REPLACED.

REAR END IS MAKING HOWLING SOUND. THE SOUND STARTED IN LATE DECEMBER OF 2019. SINCE THEN I HAVE ONLY DROVE THE CAR TO THE REPAIR FACILITY THIS WEEK. CERTIFIED REPAIR FACILITY IS STATING MY DIFFERENTIAL IS NEEDED TO BE REPLACED. *TR

BOTH HID HEADLIGHTS WENT OUT AT THE SAME TIME AFTER LESS THAN 1000 HOURS OF USE. THEY WENT OUT WHILE DRIVING AT NIGHT.

I WAS BACKING OUT OF MY PARKING SPACE WHEN I HEARD A NOISE AND REALIZED THAT I COULD NOT TURN THE STEERING WHEEL. I MOVES THE CAR FORWARD INTO THE PARKING SPACE AGAIN AND A MESSAGE ON THE DISPLAY SCREEN READ TO SERVICE POWER STEERING. UPON MY RESEARCH THE ELECTRICAL MODULE OR MOTOR HAS BEEN KNOW TO STOP WORKING. I WAS NOT DRIVING AND I THANK GOD FOR THAT BECAUSE THE STEERING WHEEL WOULD HAVE BEEN IMPOSSIBLE TO TURN. RESEARCHING THE PROBLEM I NOTICED THAT THE 2013 CADILLAC ATS HAD MAJOR PROBLEMS WITH THE ELECTRICAL STEERING. THE NHTSA SHOULD LOOK INTO THIS PROBLEM. MY CAR IS THREE YEARS OLD AND SHOULD NOT HAVE A PROBLEM WITH THE STEERING SYSTEM. THESE ELECTRICAL POWER STEERING SYSTEMS CAN CAUSE DEATH BECAUSE OF THE HIGH DIFFICULTY TO STEER IF ON THE ROAD. STEERING IS NEARLY IMPOSSIBLE.

STARTED VEHICLE AND WENT IN RESERVE. THEIR WAS NO RESPONSE FROM THE BRAKES AS I PRESSED ON THE BRAKE PEDAL, THE VEHICLE CONTINUED TO MOVE REARWARD. I HAD TO APPLY HARD PRESSURE TO STOP THE VEHICLE. BRAKE PEDAL BARELY MOVES AS I PRESS IT. HARD TO STOP VEHICLE.

THE HEADLIGHTS DO NOT PROVIDE ADEQUATE ILLUMINATION UNDER ALL DRIVING CONDITIONS. I AM A RETIRED AIRLINE PILOT WITH 20-20 VISION. THE CITY I LIVE IN DOES NOT HAVE SIDEWALKS AND I HAVE HAD SEVERAL CLOSE CALLS WITH STREET WALKERS THAT CAN BE EASILY SEEN BY OTHER MAKES AND MODELS. NHTSA RATES THE 2015 CADILLAC ATS WORST HEADLIGHTS ON MID-SIZE CARS. AS A CADILLAC OWNER SINCE 1977, I HAVE BEEN A SATISFIED CUSTOMER UNTIL THIS ATS. WHEN I BOUGHT THE ATS, I ASSUMED IT HAD GOOD STEERING, BRAKES, TIRES, WINDSHIELD WIPERS, AND HEADLIGHTS. I HAVE CONTACTED CADILLAC CUSTOMER SERVICE SEVERAL TIMES IN THE LAST 12 MONTHS BUT HAVE RECEIVED ONLY ACKNOWLEDGEMENT OF MY COMPLAINT. THIS CADILLAC ATS IS A DANGER TO DRIVE AT NIGHT BECAUSE OF INADEQUATE AND POORLY DESIGNED HEADLIGHTS. CADILLAC SHOULD REPLACE THESE UNSAFE HEADLIGHTS IMMEDIATELY. THANK YOU. *TR

FIRST IN LINE WHILE STOPPED AT A LEFT-TURN LIGHT ON A CITY STREET. LIGHT TURNED GREEN, BEGAN TO ACCELERATE. MID-WAY THROUGH THE TURN, HEARD A "POP", LOST STEERING CONTROL, AND THE REAR END SPUN CAR INTO THE CURB. KEEP IN MIND THIS IS A 4-WHEEL-DRIVE CAR. WHEN THE CAR CAME TO A STOP, THE NOSE OF THE CAR WAS RESTING ON THE FRONT PASSENGER TIRE AND WHEEL. THE RIGHT-REAR WHEEL WAS SCRATCHED AND ABRADED ALL AROUND BECAUSE IT WAS STILL SPINNING WHEN IT HIT THE CURB. THE FRONT RIGHT WHEEL HAS DAMAGE ONLY ON HALF OF IT BECAUSE IT STOPPED SPINNING WHEN THE NOSE DROPPED ONTO IT. LOOKING UNDER THE CAR I SAW THE FRONT-RIGHT LOWER CONTROL ARM BROKE IN MID-TURN. IN ADDITION TO FRONT RIGHT SUSPENSION DAMAGE, VEHICLE RECEIVED DAMAGE TO RIGHT REAR SUSPENSION. NO DAMAGE TO BODY FROM THE INCIDENT. GM HAD A REPRESENTATIVE INSPECT THE CAR AND PULL THE "BLACK BOX" DATA ON OCTOBER 8, 2015. MAXIMUM SPEED DURING THE INCIDENT WAS 38MPH. WERE ABLE TO JACK UP THE CAR. FRONT WHEEL HANGING LOOSE AND EASY TO MOVE BY HAND. STRUT/SHOCK/SPRINT TOWER ATTACHMENT BROKEN AT WHEEL HUB BEHIND BRAKE DISK. FRONT 4-WHEEL-DRIVE-AXEL BROKEN. ANTI-ROLL BAR LINKAGE BROKEN.
