NHTSA complaint #11509779

Owner complaint summary

After my test, here's what I found: If the cruise control is Off and you press and hold the cruise control button for more than 2 seconds, the speed limit function activates as indicated by the "Limit" indicator on the multi-function display. In this mode, if the vehicle speed exceeds the limit speed and you press on the gas, the power is immediately cut off, and you can't accelerate. If the vehicle exceeds the limit speed, a warning bell will sound, and the speed will flash and power is cut when pressing on the gas. If the cruise control is ON, and you press and keep holding the cruise control button, sometimes the car will begin to slow below the set speed and continue to slow, even after releasing the cruise control button, and sometimes the cruise control will remain engaged after releasing the button. In this scenario, if you press on the gas to accelerate, the power is cut out and nothing happens even though you are below the limit speed. To restore power, you have to press and release the cruise control button to deactivate the cruise control. It's as though the cruise control gets into a mode where it won't hold speed, and pressing on the gas does nothing. This seems like a software bug. The above scenarios only happen when the cruise control is ON. Power is always available when the cruise control indicates that it is not activated or when in "Normal" (non-limit) mode when active. It seems counterintuitive that accelerating manually by pressing on the gas is overridden when in the "Limit" mode. I don't know if this is a design feature or a flaw. The vehicle lost power several times in traffic - and at that time do not believe the cruise control was being used The dealer says they cannot ascertain the problem and have referred it to an executive higher-level
