Backup Camera issues. I have had my 2020 XT6 Cadillac in for service three times. They have not been able to fix the issue. This is an intermittent issue at times and other times it stays off for a long period of time. I have a black screen with a camera with a red circle and slash showing along with a triangle with an exclamation mark in the center of the triangle. These vehicles have multiple blind spots and with a camera not working and the blindspot warning not working it makes this vehicle very unsafe for use. I've been told they can not do anything until I take a picture of the black screen. I am taking possession of the vehicle again and I can send you the repair tickets at a later time.

POWER TRAIN

3 complaints

Transmission shudder at low RPMs. Feels like transmission should down shift sooner, but it shudders and shakes until RPMs get up higher. Does it when RPMs are around the 1500 mark. Vehicle almost seems like it will stall unless you give it more fuel to get RPMs up higher.

Mar 16, 2025

Vehicle has a high-pitched whining noise when cold. Vehicle also has a transmission shutter problem at lower RPM. I do not think the two are related rather than two separate incidences. But cannot be confirmed that they are two separate. Maybe one problem only. I do have video of this happening. Cannot upload a video though.

Mar 16, 2025

Intermittent shifting problems. Is stuttering when shifting. There seems to be an ongoing problem according to online and G M itself why isn't this recalled. There is no starting point it is intermittent on going. At the 1st instance they recorded it but it didn't get fixed and now they want to see it happening again but it's intermittent how many times do I have to go back

ALL CAMERAS STOPPED WORKING. WHEN CAR IS PUT INTO REVERSE THE SCREEN GOES BLACK WITH A RED TRIANGLE (WARNING) AND A RED CAMERA WITH A CIRCLE AND SLASH THROUGH IT (NO CAMERA). SERVICE DEPARTMENT INDICATED THAT THERE IS A SERVICE BULLETIN (PIC6420A), BUT PARTS ARE NOT YET AVAILABLE. THEY SAID THERE WERE SEVERAL INTERMEDIATE "FIXES" THAT DIDN'T WORK AND NOW GM IS SUPPOSED TO BE RELEASING NEW COAXIAL CABLES TO FINALLY FIX THE ISSUE. SO IN THE MEANTIME NO CAMERAS....

Vehicle has a known condition with many same year make and model that could cause the engine coolant thermostat to open at a lower temperature than intended. This condition has occurred. As a result the Malfunction Indicator Lamp (Check Engine Light) illuminates and a diagnostic trouble code is set and “steering assistance reduced” appear. The engine cooling fans also run after the engine is switched off. A recent bulletin has been posted to the 2021 Cadillac XT6 but is present in our 2020 as well. Upon calling the dealer our VIN was not on said recall/bulletin.

STEERING,POWER TRAIN,ELECTRICAL SYSTEM

1 complaint

There is a known problem, which Cadillac refuses to recall, regarding a steering assist reduced warning. The warning light disables the air conditioning system and steering assist. When the light comes on, reduced power to the steering system occurs. I took the vehicle in to be serviced, but the service light was off, and Cadillac refused to fix it; intentionally trying to run the timer out on the 5year/70,000 powertrain warranty. It's a known issue, all over the internet. In fact, they recalled several models due to the same problem. "19V-086 / N182182760 Recall Summary If the steering assistance is not available, extra effort would be required to steer the vehicle, and this would increase risk of a crash. General Motors LLC (GM) is recalling certain 2016-2018 Cadillac CTS, and 2017 Cadillac ATS, Chevrolet Camaro, and Chevrolet Corvette vehicles." I've reset the light several times, and it usually stays off for several days before returning. This sounds like a software problem, but Cadillac has not taken any steps to fix the issue. It is dangerous for any reduction in steering, especially during winter or at highway speed. It's also dangerous to disable air conditioning, as during the summer, the temperature can reach above 140 F inside a vehicle. If a driver were to have a medical event in a parking lot, or fall asleep with the vehicle on while simply waiting for somebody -- while assuming the air conditioner would keep them cool and comfortable -- within 10 minutes the temperature could reach 130+ degrees, and into the 150s in California or Las Vegas. Software should never reduce steering assist, or disable the air conditioner automatically. I would like a recall to be issued regarding this problem. I don't know if they have designed the system to fail right at the warranty or just after, but it certainly appears that way. Please look into the matter. Cadillac has refused to repair under warranty. [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was waiting for a light to change to green and the vehicle shut down because of the auto-stop feature, after a couple of seconds the car turned on again and this message came on "stability track off" and this happened like that like 3 times until I turned off the auto-stop. I took it to the dealer the next day and they scanned it for issue and told me there's nothing wrong with the vehicle.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE

1 complaint

While reversing at a downward slope, sudden strong braking will occur. It does not always happen but when it does it is very alarming and loud. I’m guessing something is wrong with the Automatic Emergency Braking system. There is no warning prior to it happening. I fear these occurrences may cause an accident if I’m not wanting to brake at that moment. I have made Michael Hohl Dealership in Carson City NV aware of this issue but they don’t have a remedy for the problem.

ELECTRICAL SYSTEM,BACK OVER PREVENTION

1 complaint

The back up camera is intermittently non functional when placed in reverse gear. A red triangle and red camera icon appear on the screen with a circle and slash through it. GM has posted a Bulletin #PIC6420 that offers a solution stating that it is likely a connection concern and recommends replacing a coax cable which can be ordered through the WPC. There have been multiple complaints about this serious problem on the Cadillac Owners Forum. I make deliveries to senior citizens homes (Meals on Wheels) with this car and need my backup camera to work. I no longer feel safe driving this car. I have contacted my dealership (Lafontaine Cadillac in Highland, Mi) and they will not accommodate a service appointment and supply a loaner car until July 22, 2022.

FORWARD COLLISION AVOIDANCE

1 complaint

Cadillac Case number is 9-6766521074. The Cadillac CT6 has a flaw in the intelligent braking assist(IBA) software. When no collision is imminent, pushing the brake even slightly results in extremely hard overbraking causing all items to fly forward. There is no way to turn off IBA without disabling the entire Automatic Emergency Braking System. To be clear, it is OK that the car senses inaccurately a collision and it is OK to apply the Automatic Emergency Braking Logic, the problem is that the Intelligent Braking Assist is too hard when a crash is not imminent and this will cause following cars to rearend the XT6 when no hazard is expected/present. As an interim, please direct Cadillac that they update there system preference software to allow customers to turn off Intelligent Brake Assist (IBA) independently while still keeping Automatic Emergency Braking (AEB).
