I put up a rubber stop to test the emergency stop feature the car is equipped with. With car moving either forward in drive or backwards in reverse the car would not automatically stop before hitting this two foot high aid. A warning vibration is felt just before the car struck the device but the way I understand it in the owners manual the car should come to a complete emergency stop.  This could endanger anyone or anything that the driver did not see while moving the car, i.e., a child on a tricycle for example.

CADILLAC CT5 2025 ENGINE

I went to test drive this car on Saturday 9/27, and noticed that the rear view mirror--the actual mirror, not the video screen inside it--was vibrating/shaking immensely as I drove it.  I told them I'd buy the car, but they have to fix the mirror.  Tuesday 9/30 I bought the car, with the assurance that the mirror had been fixed.  Apparently there's a screw that was loose.  Upon leaving the dealership, I discovered that the shaking/vibrating hadn't gone away--it was merely diminished.  I took the car back.  We discovered another identical model and year of the car on the lot, and it exhibited the exact same problems.  Initially the same screw was loose, but after fixing it that mirror also gave the same shaking/vibrating.  We determined that this looks like an overall problem with this model and year, at the least, and the dealership didn't know what to do.  I declined the car.  This is a serious issue with rear visibility.  The rear view mirror is almost unusable, and it's almost illness-inducing to see in action.
