2017 Hyundai Santa FE Sport Fuel system Problems

“1.) on april 20, 2018 stopped on a hill for a red light when the light turned green and I took my foot off the brake and put on the gas, the car went backwards. This happened on a busy city/hospital district and thankfully no one was behind us. 3.) it happened again on july 21, 2018 on a city street with no one behind us. Dealership said they couldn't recreate this. 2.) when someone puts a pillow under them on the passenger seat the air bag does not work. This happens if the car is stationary and in motion.”

“This vehicle has dangerous hesitation issues at lower speeds. I drive in heavy slow traffic frequently and changing lanes or accelerating at lower speeds is dangerous and I fear an accident could easily happen. When travelling at speeds below 20mph and there is need to accelerate to change lanes, the vehicle hesitates when the gas is applied. It can be for 3 or 4 seconds before the vehicle actually accelerates, by this time, the cars coming up in the lane I'm moving into, have to slow down to avoid hitting me. …”

“Intermittently the vehicle will hesitate during acceleration from a standing start. It appears related to turbo lag, but to the extreme and is a dangerous safety issue. Most recently, as I went to takeoff I was momentarily stalled in the middle of the street as I was pulling into on-coming traffic. This is just the opposite of what a turbo boost is supposed to provide. This issue is well-documented on the Hyundai auto forums and needs to be addressed immediately. Again, this not an inconvenience. It is a safety hazard and Hyundai seems unconcerned about solving this issue. …”

“After having recall service completed on gas tank area, ( flvv pump fuel replaced on jan 11th 2018) I noticed after filling the vehicle with fuel to full capacity, a very strong odor of fuel is present on the exterior of the car when I park it inside an enclosed area (garage). This gasoline smell persists until I use 1/8th of the tank by driving. Hyundai dealer service inspected and stated it is a small leak as a history code and performed evap. Service bay test pass. Actuated purge valve and found it sticking. Ordered valve . I am waiting for part per dealer to be installed upon availability.”

“When driving in normal and sport mode, on acceleration there is a delay and when the gas is left off, the engine is revving high but propulsion, speed is diminished, having a stall out affect at varying speeds. Rpm is high but engine is not responding . This has happened weekly and nearly daily when driving in city environment with speed from 30 to 50 plus miles per hour.”
