We bought our Clarity in mid-August and currently have about 7,000 miles on it. Really love the car, despite a few quirks. But an experience we had 10 days ago really shook our confidence. While driving on a 4-lane freeway -- thankfully in the middle of Iowa with little traffic -- shortly after the automatic shift to the ICE when the battery ran out, the engine revved up and we simultaneously lost all power to the wheels. It was as if the engine had been suddenly disconnected from the transmission. My wife was able to guide the car to the side of the road safely as it decelerated outside of our control. We turned it off, then back on, hoping maybe a computer just needed to be 'reset'. As we tried to get back on the freeway the engine/transmission were on again, off again, as if the transmission was engaging, then not. Gradually we got back up to speed and were able to complete our journey. After sitting for 5 hours or so a similar thing happened on our way back home on a 2-lane road, soon after we got out of the parking lot. No problems the remaining 1.5 hour drive. After comparing notes, my wife and I realized a similar thing had happened to each of us, but at very low speeds around town during the past 5 months, so not that noticeable. And it's happened once in the past week, also at low speed in town. Can't imagine how dangerous this would be if it happened on a full speed freeway in a city of any size or while in mountain territory. Immediately called our local dealer and the car is in the shop today...we'll see what happens. A great car, but not worth risking my family's safety.
