Car Will Not Accelerate Problems of Hyundai Veloster

Purchased car on 5/5/2012 with 6 miles on it. Within less than a week and 200 miles the transmission began clicking. Took it into Hyundai and they stated it needed a new transmission. After 2 1/2 weeks the transmission was replaced as Hyundai refused to give me a different car. Since then the car cannot accelerate, sounds "clunky" and when going at low speeds sounds like the gear isn't engaging and sounds/feels like it would if you released a clutch too early. Car loses power and sounds like it's about to die. A hissing and rattling sound under the hood happens as well. After taking it in to dealer, dealer states they could not find the sounds or noises or loss of power I was having. Rpms rev really high before engaging in first gear. Dealer still won't do anything since they can't diagnose it. I have almost been in multiple accidents for failure of power and car not accelerating. Takes about 3-5 seconds before it goes. Brakes grab too easily as well. Loss of gas mileage (around 6-7 mpg) was reported to dealer but dealer told me it was due to "winter gas. " I can understand 2-3 mpg difference but 6-7 is too much. Car has also been in the shop for a week for the car alarm going off constantly for no reason. A piece of the windshield plastic also fell off for no reason when car was 3 weeks old. Dealer duct taped that part down until a new part could be ordered.
