SEATS

The airbag warning light appeared 45 days ago. I immediately took my 2017 Cadillac to the dealer (Sewell Cadillac of Houston). The vehicle is covered under a Sewell Extended warranty until 2028. The dealer performed troubleshooting and determined that the passenger seat sensors/module (part # 84567224 ) was defective. The Inspector for the Sewell Extended warranty confirmed that the replacement was covered by the warranty. The dealer advised after 30 days (completing other services- Brakes/rotors/front tires/spark plugs & wires etc) that the part # was “Back-ordered” and Sewell did not know when the part would be available, if ever. The consequence explained that the passenger seat which contains GM Part # 84567224 should not be used as the airbag may not inflate. Now the dealer wants their “loaner car” back and for me to pick up my “unrepaired Safety defective seat in my car”. Today’s date: December 20, 2025. The car was purchased new 11/2016 from the same Sewell Cadillac dealer. I would expect that General Motors be compelled to supply critical safety related equipment (part # 84567224) for a 8 year old car.

The power steering went out on the vehicle. I was not driving at the time. There was a recall on these vehicles pertaining to the EPS module.

POWER TRAIN

I purchased this vehicle is certified preowned Cadillac and during the warranty time I had a transmission issue that was causing the transmission to jerk when shifting from 1st to 2nd gear and at highway speeds, it would start jerking nonstop. I took it to the dealer and as per a service bulletin, they flushed the transmission fluid and replaced the transmission fluid. This was only a temporary fix because 30,000 miles later the same issues started occurring again and have gotten worse to the point that you can smell the transmission clutches burning and the transmission overheating, possibly causing the number four piston rings to come apart, resulting in an engine replacement as well. I’ve had to replace engine as possible result, but the transmission problem is still there and it has also caused the check engine light to come on intermediately. This could result in a complete transmission failure, causing a vehicle to lose propulsion leading to a possible accident and injuries. This issue needs to be investigated and repairs or replacement made at the manufacturers expense.. This is a four-cylinder turbo engine and an eight speed automatic transmission. In my opinion, the transmission issue caused my engine failure. There should be investigated and an immediate recall issued.

The Cadillac CUE screen cracks and becomes unresponsive. When driving this is effecting anything related to system including navigation, radio, hvac, phone and all other functions creating a distraction to the driver that could lead to an accident. This is not the first time that this has happened to me and I’ve noticed that each time the issue is created is during hot days in southern states. This has never happened during the winter. This is my 2nd Cadillac in a row that has had this problem repeatedly. Happens every 2 to 3 years. This might not seem like an issue but it poses a major safety hazard to all people in vehicles around them and an immediate recall and investigation should be taken seriously. A lawsuit was settled for some owners but all owners should be notified and repairs should be completed at the manufacturers expense regardless of age or mileage.

OnStar is unable to communicate with my vehicle. When I bought the car 2 years ago, it connected fine. Not OnStar is unable to ping my car. Appears the. Module goes out on a lot of cars since I was told it is on back order and not sure if that was the true peoblem

I began hearing a “hum” when driving my vehicle and dismissed it thinking it was the type of low profile, no flat tires. After a getting new tires, brakes, brake pads, and control arms, we still heard the “hum” and it continued to get louder. We took the car to 4 different places where they all stated the rear differential is the problem. I never had a service engine light come on. We found out that there was a recall on this part for other Cadillac CTS vehicles but my VIN did not come up as one that has a recall. I have had my rear differential fluid serviced and changed right before 30K miles. I now have a little over 95K miles and am told there is a back order for this part due to how many other Cadillac CTS vehicles are having the same issue. This could make car lock up at any time while driving. I transport my grandchildren and elderly Mother in this vehicle regularly. We have been told that it will take over $6K to fix and since the part is on back order, it will be several months before it can be fixed. This is not only a dangerous and possibly deadly circumstance, but extremely inconvenient and expensive. This part needs to be recalled for all Cadillac CTS vehicles and the parts need to be available as soon as possible.

Unknown I have been driving my car for 2 years now. For about the last year the steering in has been handling horrible and I have checked all parts every think is in good condition. I have read online it's a common problem and I see it as a safety concern especially since it's recalled on the same vehicle different vin. So when driving down the highway it's hard to stay centered and the car pulls different directions and the steering gets stiff to where it feels locked up. It is electrical power steering and I have experience from a prior experience with a 2009 pontiac g6. All these parts should of been recalled and not just a handful.

Passenger sensing device for the passenger seat is failing intermittently. Service airbag light is coming on periodically, and, when it does, the passenger "Airbag ON" light fails to illuminate even if a passenger over 100 lbs is in the seat. This is a long recurring issue with all GM cars where the sensing pad goes bad.

Rear differential failed on a vehicle with 60,000 miles and required a $4,200 repair. The manufacturer warranty covers up to 70,000 miles, but the age of the vehicle voided the warranty. Five Year manufacturer warranty and the vehicle is 7 years old, but within the mileage. Without the repair the vehicle is worthless, whereas it is worth @$14,000 {Kelly Blue Book}. Checked online and it is not uncommon for this model and the newer CT-5/6 models to have this issue.

The rear differential has failed in my vehicle, and I was told by the dealer it is a safety hazzard & could lock up, leave me stranded or cause an accident. (this is the same safety issue as thousands of other vehicles most from 2014 & 2015 that IS on a recall).

ELECTRICAL SYSTEM

our 2017 Cadillac CTS-V has all of a sudden a cracked CUE screen. The car is garage kept and only has 14395 miles. It just spontaneously cracked. The dealer that is fixing it is making us pay $125 deductible to get it fixed even though there is a class action law suit currently for others that have this same issue. The whole CUE screen cracks in a spider web like formation and makes the screen very difficult to read.

CADILLAC CUE INFOTAINMENT SYSTEM WORKS MAYBE 25% OF THE TIME. THE OTHER 75% THE SYSTEM IS UNRESPONSIVE AND GLITCHY. I CAN NOT ACCESS SOME OF THE MOST IMPORTANT FEATURES. THESE SAME FEATURES ARE THE REASON FOR THE INITIAL PURCHASE. BUT BEING THAT I CAN'T USE THEM WHEN I NEED THEM, I AM NOW REGRETTING THE PURCHASE. THIS IS TOO NICE OF A CAR FOR THE BASIC CONTROLS NOT TO BE WORKING MAJORITY OF THE TIME.

THE CADILLAC CUE COMPUTER SCREEN WHICH CONTROLS THE BLUETOOTH, RADIO & GPS, FROZE IN SEPT 2019. WHILE DRIVING OUT OF STATE OUR BLUETOOTH & GPS WERE UNAVAILABLE. THE DEALERSHIP COULDN'T DUPLICATE THE ISSUE. THIS WAS HAPPENING IN DIFFERENT LOCATIONS, A COMPLETE OFF & ON WITH THE SCREEN GOING BLACK. DEALERSHIP AGAIN & THEY COULDN'T DUPLICATE THE ISSUE. THE DEALERSHIP IS AN HOUR DRIVE EACH WAY. I LEFT FRUSTRATED & AND IT WENT OFF AGAIN. I WENT BACK TO THE DEALERSHIP & IT WAS PLAYING WHEN I GOT THERE. WHILE WE WERE DISCUSSING THE ISSUE, THE RADIO WENT OFF. WE WAITED AND IN A COUPLE OF MINUTES IT CAME BACK ON. THEY DIDN'T HAVE A LOANER VEHICLE AVAILABLE SO I HAD TO COME BACK SEVERAL DAYS LATER. I MADE THE TRIP AGAIN AND LEFT MY CAR WITH THEM. WHEN THE RADIO WORKED FINE AGAIN, ONE OF THE SERVICE GUYS WONDERED IF IT MIGHT BE THE BLUETOOTH RELATED. HE LINKED HIS APPLE IPHONE TO MY CAR'S BLUETOOTH & WAITED. THE RADIO WENT OFF & IN A FEW MINUTES CAME BACK ON. HE HAD FOUND THE PROBLEM. HE CALLED GM CORPORATE & THEY CONTACTED APPLE. APPLE IS AWARE THAT THEIR LATEST UPDATE IS CAUSING THIS ISSUE & ARE WORKING ON AN UPDATE TO FIX IT. THIS REVELATION ANSWERED THE ISSUE THAT THIS DEALERSHIP WAS HAVING WITH TWO OTHER VEHICLES IN THEIR SERVICE CENTER THAT HAD A DIFFERENT VERSION OF THE CUE. SO FOR NOW I HAVE TO CHOOSE BETWEEN HAVING GPS & A RADIO OR HAVING MY IPHONE BLUETOOTHED & HANDS FREE. IT IS NOW DECEMBER 2019 AND APPLE HASN'T CORRECTED THE ISSUE. HOW MANY 'HANDS FREE' VIOLATIONS AND ACCIDENTS WILL THERE BE BEFORE THIS GETS FIXED? I REALIZE THIS IS AN APPLE ISSUE RATHER THAN A GM ISSUE BUT I JUST BOUGHT THIS CAR 7 MONTHS AGO & THE SAFETY FEATURES, INCLUDING GPS & BLUETOOTH PLAYED A BIG PART IN MY DECISION. I'M REALLY FRUSTRATED IN NOT BEING ABLE TO USE ALL OF FEATURES OF THE CUE SYSTEM. I'M WRITING THIS IN THE HOPE THAT GM WILL PROGRESSIVELY WORK WITH APPLE TO GET THIS RESOLVED.
