Each component in detail
What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
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.
This new 2025 Cadillac CT5 displays incorrect posted speed limits on Rte. 114 Flanders Rd, Gulf Rd, Bear hill Rd , .Ryan Rd, in Henniker NH. speed of 55mph which is incorrect to legal posted speed limits being much slower. This vehicle also shows roads that have no posted speed limit sign of 55 mph, which should be for safety reason(--) Can we have these roads updated to display the correct posted speed limits from the third party supplier /google.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
Rough idle, reduced acceleration, engine failure requires engine/motor to be replaced. Only 4300 miles on car. Purchase date 6/21/2025. Failure10/25/2025.
I just bought a new car 5 days ago, and after running 378 miles, it started to pull the cylinder. The after-sales service is still delaying the time. I don't know what to do, and Cadillac still doesn't give me a mobility scooter.

From owner reports, verbatim
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.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
