What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There was nothing in front of me that should have caused this safety system to engage.I beleive they call this phantom braking. Because I had just started up from the light, my speed was slow and we sustained no injuries. However if that happened on the freeway I travel quite frequently, I would have been killed.
My XT4 had no warning lights or diagnostic messages indicating any malfunction prior to the crash. This failure closely resembles previous complaints noted in NHTSA filings (e.g., ABS sensor failures, OnStar module failures, and the 2025 XT4 passenger airbag recall).
ie: brakes, propulsion, headlights, air bags, etc etc etc...Cadillac dealer who fixed the issue said that it is a common problem and not warranted and my car has no warranty anyway.
While driving the complete dash will go black: no radio, gauges, speedometer, etc. The total blackout lasts for about 30-45 seconds and then different gauges, speedometer, etc will slowly come back to life.
Purchased used with 30k miles and under factory bumper to bumper warranty. Noted noise when turning right slowly into parking space from front suspension as well as pop sound while going over speed bumps. Dealer replaced 3 axles (2 driver side) and confirmed noise present.
The contact stated that while driving at an undisclosed speed, the passenger’s side rear tires experienced a blowout. The vehicle was taken to the local dealer, where the tire was replaced, but six months later the driver’s side tire experienced a blowout, which caused significant damages to the driver’s side fender…
