What owners report most
Forward collision avoidance
“CRITICAL SAFETY SYSTEM FAILURE & CONCEALED SOFTWARE REPAIR: Within 14 days of vehicle delivery, a 2026 Cadillac CT5 experienced a complete failure of its heavily advertised Reverse Automatic Braking (RAB) driver-assistance technology. While reversing at a safe, low speed toward a full-sized stationary vehicle, the system failed to detect the obstacle, issued zero visual/audible warnings, and failed to apply automatic braking, resulting in an unmitigated collision ($2,800 physical damage). SUBSEQUENT OEM CONCEALMENT & SOFTWARE FLASH: The vehicle was taken to an authorized dealership (Wallace Cadillac). While in dealer custody, onboard vehicle logs confirm that GM Update 661.10 was flashed to the vehicle's modules on June 8th. GM Corporate and the dealership subsequently claimed no repairs or updates were performed, stating the system tested "fully functional" on June 13th (after the undisclosed software patch was applied). GM Executive Management (Case #103080717 / PAC Case #101155599) has repeatedly refused to provide written diagnostic findings or supply the owner with the Event Data Recorder (EDR) telemetry logs as requested under the Driver Privacy Act of…”
Service brakes
“Component/system involved: Electronic Parking Brake (EPB) system and EPB control switch on my Cadillac CT5-V Blackwing. The vehicle and component are currently available for inspection. What happened / safety risk: The vehicle experienced an unattended roll-away and struck a tree, causing significant vehicle damage. No one was injured, but the vehicle’s uncontrolled movement created a risk of serious injury or property damage. Reproducibility: After the incident, I discovered that I can reproduce a behavior in which the electronic parking brake is released and, if I actuate the EPB switch again shortly afterward to reapply the parking brake, the vehicle sometimes does not respond to that second input. The parking brake remains released and the expected parking-brake indication does not appear. If I wait longer and actuate the switch again, the parking brake applies normally. I have video showing this behavior. The issue has not yet been evaluated or confirmed by a Cadillac dealer. Inspections: The vehicle has been inspected in connection with the collision/insurance claim, but the EPB behavior has not yet been evaluated by Cadillac/GM or an independent service…”
