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)

NHTSA ID 11774077 · filed Oct 27, 2026

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.
