I bought a 2013 Accent not knowing it has a "hill assist." Much of the area I drive in has no hills but when I release the brake at a stop light it still takes a couple seconds for it to release. What can I do to fix this issue? I do like it whenever I go into downtown Seattle. Can you tell me what I can tell the mechanic to fix this? Thanks.

Brandy Schaffels, Editor at AskPatty.com, Inc. We published an educational story about Hill Assist technology here at AskPatty: http://caradvice.askpatty.com/ask_patty_/2014/07/how-hill-hold-or-hill-start-assist-technology-makes-steep-road-starts-safer-for-drivers-.html Hill-start Assist (HSA) keeps the brakes on briefly, after the driver's foot is moved from the pedal, to easily allow “non rollback” on hills. Hill-hold technology essentially offers an “extra foot” to manual transmission drivers to help novice and veteran clutch-shifters better manage hills, but we're also seeing it more frequently on automatic-transmission cars as well. “As fuel-efficient CVT transmissions with low-creep torque and low internal friction become more common, so does rollback on inclines,” explains to Nate Berg, Manager of Vehicle Testing for Mitsubishi Motors North America. “Drivers of manual-transmission-equipped cars are better prepared for such rollback, but drivers of automatic-equipped cars can find it quite disconcerting,” Berg says. In a vehicle equipped with hill-hold, a pitch sensor detects the tilt of the body when the car is stopped on a slope and sends a signal to the vehicle's brake hardware to keep the wheels clamped for a few seconds after the driver releases the brake pedal. This can be helpful whether your car is pointed uphill or down. The feature should not intrude into regular driving on level roads, and its operation is not really something you can "Fix." If your vehicle is equipped with it, it's really not a feature you can disable, though you may be able to talk to your mechanic to find out more about it.
