My car started to lose speed, slowing to 27, then about 22-24 mph. I felt as though the engine was misfiring for an unknown reason.  Since I was approaching an intersection and needed to make a left-hand turn, I started to depress the brake pedal. With no oncoming traffic, I slowed not quite to a stop, made the turn, but then had extreme difficulty getting the car to accelerate, again with the engine sputtering, chugging like a misfire, and shaking. My vehicle did not seem to go beyond 15 mph, and slowed again as I turned into my destination, about 2-3 blocks from the intersection. I parked and locked the car and was in a store for approximately 10 minutes. When returning to my vehicle, it would not start-the brake pedal could not be depressed at all, it appeared extremely hard. After 1-2 minutes of gently tapping the brake pedal, it loosened and I started the car. I put the car in reverse and it stopped in the middle of the parking lot with cars almost hitting me. I saw Engine Warning lights, Battery Warning lights, and a quick message across the screen but was unable to capture the meaning. After several more attempts, the engine started but was shaking violently, but I could not go beyond 3 mph. The shaking was so strong, items on the passenger seat shifted on the floor. I chose to remain in the parking lot and call Hyundai Bluelink. Since it was dark, I remained in the vehicle with the engine running, but excessive smoke billowed from the rear of the car. It was towed to Gerald Hyundai in North Aurora. After 3 days the dealer could not find any issue, however, I refused to take the car back, as I could recall it misfiring in previous weeks but unfortunately dismissed it. I requested a Technical Case File be opened at the Dealer.  I still do not have my car after 1 week. This is a very serious issue and I am aware other owners have experienced it as well.","products":[{"type":"Vehicle","productYear":"2022","productMake":"HYUNDAI","productModel":"TUCSON","manufacturer":"Hyundai Motor America"}]}]}
