1. Filed May 26, 2026MIEngineSteering

   Check engine light sensor came on in mid-May which is the result of a faulty thermostat, also triggering a "Steering Assist is Reduced" message on the dashboard which I consider to be a safety issue. This is a known and common problem for this make, year and model and the cost to fix the problem is very expensive. This issue has been reported by many Cadillac owners on their forum. My mechanic confirmed the problem with the thermostat caused the steering assist is reduced…

   Thermostat failure causes steering assist to be reduced. This leaves more difficult steering especially in an emergency situation, thus a safety concern. The vehicle displays a warning: "Steering Assist Is Reduced, Drive with care". An internet search shows this is a well-known problem across all General Motor vehicles. This is also indicated by the technician notes on my repair invoice that a bulletin from the manufacturer has been issued. After restart the warning clears…

   While driving at highway speeds, I needed to accelerate hard in order to pass another vehicle and while accelerating there was a downshift and increase in RPM. After passing, the RPM remained high even after I took foot off accelerator and it seemed the transmission did not shift back out of lower gear, keeping the car traveling at a high rate of speed, endangering myself and other traffic.

6. Filed Dec 9, 2025OKBrakes

   Brakes failure. Approaching a busy intersection and facing a red light, I slowed and prepared to stop the vehicle. Nothing happened with regard to braking; instead, the engine seemed to rev up as it continued through the red-lighted intersection with 2 lanes of busy cross traffic from both directions. That there was not a collision is a miracle. I also noticed some flashing displays on the display screen, though hard to take time to read them while avoiding a crash and still…
