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.

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.
