 When I first purchased the vehicle I noticed a significant delay between pressing on the gas pedal and acceleration.  Within one week of driving the Tuscon I was almost in an accident because the SUV was slow to respond through an intersection. I reported this to the dealer and was informed by one of his  technicians that there was a recall  and a software update was needed. The update was only moderately successful. The transmission is unpredictable in how it responds to steep hills, sporadically jerky, and still, at times, slow to accelerate only now its inconsistency keeps you sweating it out at busy intersections. Every passenger that has been in this vehicle has commented on it. I've talked to the technician and he told me this is the nature of a dual clutch transmission but he would look at it. I have told the owner of the Hyundai dealership on two occasions that I believe this vehicle is unsafe and should not be on the road.
