Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Crash reported

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 2015, communicating denials strictly via telephone to avoid a paper trail. This issue directly correlates with ongoing federal investigations into GM electronic brake control module failures. The failure of active safety collision-avoidance systems poses an immediate, severe safety risk to vehicle occupants and pedestrians.

Adaptive Cruise control acts like it’s going to maintain a gap (user selectable gap distance is able to be manipulated and displayed on drivers information center) but will rush right onto a preceding cars bumper. I’m told that even though manual transmission cars have the components and illusion that adaptive cruise control works, it doesn’t which is bad if you think it will work. Please make adaptive cruise control work in manual transmission CT5s like it does in auto. Similarly, the Surround Video Recorder equipment is installed but doesn’t record and isn’t viewable. Please make that function as well. Again, all of the hardware is there - implement it!

While driving vehicle at approximately 50 mph in normal driving conditions, the vehicle’s automatic emergency braking/forward collision system activated an alert when a vehicle ahead of me slowed and turned out of my lane. After the lane was fully clear and there was no obstacle in front of the vehicle, the system aggressively braked and brought the car completely to a stop on the highway. During the event, the vehicle temporarily would not respond to accelerator input even while pressing the gas pedal. This created an extremely dangerous situation and nearly resulted in a high-speed rear-end collision. No crash occurred, but if a larger vehicle such as a semi-truck had been behind me, serious injury or death could have resulted. I am reporting this as a potential false automatic emergency braking / phantom braking event. Vehicle is a rental, history unknown…

The contact owns a 2026 Cadillac CT5. The contact stated that while driving the vehicle with the Super Cruise feature activated, the message indicated a road construction zone, and the brakes independently activated. The contact stated that there was no road construction nearby. The contact reset the super cruise control feature. The contact stated that while the super cruise control was set at 75 MPH, the vehicle unintendedly accelerated to 100 MPH within seconds. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The dealer was made aware of the failure; however, the contact was awaiting scheduling information. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to cease using the cruise control feature until the vehicle was inspected by the dealer. The failure mileage was approximately 1,200.
