EXTERIOR LIGHTING, STEERING, ELECTRICAL SYSTEM
UNACCEPTABLE SAFETY HAZARD: General Motors & Cadillac Need to Take Responsibility I am writing this to urge Cadillac and General Motors to address a critical safety issue before someone gets seriously hurt or dies. While driving my 2020 Cadillac XT6 over an overpass in XXX, the vehicle suffered a complete electrical breakdown. Every dash light flared up, and I instantly lost total control—NO steering assist, NO acceleration. Being stranded in a moving vehicle without control on an elevated roadway was terrifying. This car has under 50,000 miles. It is currently on its 6th service visit at Stevens Creek Cadillac and has been sitting in their shop for 3 full weeks with zero answers or progress. I trusted Cadillac again even after my 2006 SRX had to be donated under 150k miles following 2 transmission replacements and endless issues. But experiencing a sudden, total power failure at highway speeds crosses every line. I am fearful to take this vehicle back. I do not feel safe put back behind the wheel. GM and Cadillac really should not sell these vehicles until their electrical issue is safe. I opened a case with GM and they said that the buy back was denied which is insane to me. this vehicle doesn't even have 50,000 miles on it. I hope someone will help my husband and I. thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
Vehicle stalled while driving on a busy road creating a very dangerous situation. Could not put it in neutral to push it out of the road; it was partially in the road for over an hour. Had to have it towed to replace the fuel pump and fuel pump control unit. Found two recalls after the incident and was told by Cadillac that my VIN was excluded. 1. Fuel Pump Assembly Recall (N202314760 / NHTSA Campaign 20V639) Fuel Pump Power Control Module Recall (N252516900) Out of pocket expense was $1173.97

POWER TRAIN
at 60,740 miles, "Steering Assist is Reduced Drive with Care" message appeared. Under warranty, but dealership booked for 2 months. Error went away. After powertrain warranty expires (70,000 miles), message constantly appears, and coolant thermostat display is BLANK. Results in excess fan usage (lowering fuel consumption), reduced steering assist, aggravation, check engine light. This issue has developed while under warranty, for a practically new car. Unacceptable. An extended warranty should be in effect for model 2020 as well.

UNKNOWN OR OTHER, ENGINE
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.

POWER TRAIN
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.

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.

ELECTRICAL SYSTEM, STEERING, POWER TRAIN
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.

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.
