In owners' words
What CX-30 owners report
Recent service brakes complaints filed with NHTSA, shortened. Personal details are removed.
Front and rear brakes premature wear, would have failed safety inspection under 30,000 miles but brakes were inspected just outside of warranty with metal on metal. RIGHT rear coil spring snapped lower middle of coil while driving on flat even ground. Just outside of warranty.
The car was running in parking garage without ignition being turned on. When I entered the car, the motor wouldn't catch at all, and message popped up saying the there was a brake malfunction. All the lights were on, so it did not seem to be a battery problem, but the drive function was dead.…
While driving across Speer Blvd in Denver, CO (6 lanes) the emergency assist brake engaged and brought my car to a complete stop. There were no cars or objects ahead of me and fortunately the cars behind me were able to stop.
