While driving, car suddenly slowed and would not accelerate as normal with accelerator depressed. A dashboard warning "check hybrid system" appeared and acceleration was unable to power car up hill. Driver forced to pull over on shoulder. After turning off and turning on vehicle, issue seemed to temporarily resolve itself. Dealer was unable to identify any faults in the car 3 days after this incident, and returned car to owner. A week later, the same issue occurred. Car would not accelerate after stop sign. When pressing accelerator, car coasted forward a a few mph. Turning off vehicle and turning on again resulted in normal performance resuming.

Hesitation upon accelerating from a stopped position. When pulling out from a stop into a busy intersection the vehicle hesitates for several seconds. I have almost been broadsided when attempting to pull out onto a busier roadway. The vehicle feels as though it is stalled, then suddenly lunges. Apparently this is a known feature of the Hyundai hybrid after reading that it is the top complaint. There are no codes or warning lights that appear. I feel this is a safety issue. A car should move when you put your foot on the accelerator and not just sit there for several seconds. Please, please have Hyundai resolve this issue. I have had my car to the dealer 3 times for this issue without resolution.
