Owners/service Manual problems of the 2015 Hyundai Tucson

Leased June 25, 2015 car engine quit while driving within two to three days. Key in locked position dealer arrived-able to start car. Explanation -perhaps key fob too heavy. Changed key fob. Last week car stopped again, engine off/key in locked position. Past three months- multiple intermittent electrical problems car taken in for service- could not duplicate. Understand intermittent electrical problem difficult to find. I asked after first event to exchange the car. Heated passenger seat came on -passenger noted . Doors lock and unlock without being locked/unlocked by owner. Hatch does not open at times, overhead passenger light on while driving. Engine runs rough. A friend drove x1 day unaware of issues. Let me know it ran rough/did not appear to engage the gears properly. The auto head light on. After going into the house noticed lights still on had to turn off manually. Have pics. - radio on by itself - told plugging in mobile phone activates radio yet radio came on/phone not plugged in. Videoed. With in the last two weeks - did not lock car returned to unload. Driver door locked, all others open, hatch would not open. Videoed. Had to open driver door manually to open-videoed. Picking up a friend -unable to open door using arm lock release- tried key-no luck. Had to open manually. 4 witnesses of events. Car not safe to drive with engine turning off in drive/on highway. Service manager helpful until told lemon law to be invoked- no further contact. Case # 8112192 filed with Hyundai/July-no response. Called Aug. /sept. Did receive a call back last week with a message indicating the situation most likely not resolved thus this email. . I am in seattle due to a family illness- no access to the video's-can send if provided a reference number to associate complaint with pictures/videos. I do not want the car and did offer to exchange in the first week .
