When accelerating from a dead stop or nearly a dead stop the car does not accelerate smoothly. There seems to be a pause and then it accelerates quickly, this caused a family member to hit a car in a parking lot.

My 2017 Santa Fe sport with the 2.0 turbo engine, hesitates all the time while attempting to accelerate or make a turn for aprox. 1-2 seconds, thus it makes for a hazardous situation, especially when you're turning in front of on coming traffic.

- Bensenville, IL, USA

When turning left or right from a stop or low speed (<10 mph) on a paved city street, intermittently the vehicle will not respond to my gas pedal. I can have the pedal all the way to the floor and the car will not accelerate. Only after 1.5 to 2.0 seconds will the car react, and when it does, it is violently fast. This causes issues when making left turns because you're going into oncoming traffic with a vehicle that is stalling for almost 2 seconds before the car begins to move forward (violently).

Acceleration issues. On at least two separate occasions, acceleration from a stop resulted in the car staying at the same speed. Had to remove my foot from the gas pedal and reapply several times to get it moving. Normally, applying throttle pushes individuals back on their seats. Car was taken to laurel Hyundai and per the techs "unable to replicate customers concern on road test, no codes stored or present in system, no tab's for concern found". looking at getting rid of this vehicle due to this serious safety issue.

Upon moving after complete stop and turning vehicle to right or left, there is hesitation before there is throttle response. It occurs more often if while initially making a turn and any size bump or pothole is encountered. A very dangerous situation as there is no way to make an avoidance maneuver if necessary since there is no immediate throttle response. The same situation occurs when at slow speeds a pothole or bump is encountered during a turn. Again, dangerous, because without a responsive throttle no avoidance maneuver is possible. N.B. I put today's date because the "field is required". it occurs on a daily basis, nonetheless.

The Santa Fe sport was purchased in July of 2017. When taking off from a redlight or while driving at a steady momentum on the road, the acceleration drops significantly and the rpms begin to rev up high, bouncing up and down, but the Santa Fe sport will stall. While on the highway, the issue continues and panic sents in due to the cars behind us can rear end the Santa Fe sport. No matter how far or hard the gas pedal is pressed the Santa Fe sport will stall. All while no "engine light" turns on. Took the Santa Fe sport for service to the dealer over 6 times between 2017 and 2018 and only an ems part was replaced. The problem continues mostly in very bad traffic, again very concerning for safety. The Santa Fe sport needs to be turned off and back on in order for the problem to cease. No matter what drive mode it is in (eco; sport; normal) the issue persists. We purchased a brand new 2017 Santa Fe sport right off the lot which has been paid for and it is unfair that we are still paying what seems like our lives we continue to spend more with gas, tolls, travel and time from work to take the Santa Fe sport in for service and we do not get refunded for this.

Purchased car in June 2017 and currently have approx. 5100 miles. When going from a standstill stop or a slow rolling start (exiting a driveway) the acceleration is lacking. Car will go high rpms but no speed. And when attempting to merge onto a road way it has become a safety concern as approaching cars from the rear close what was a safe distance to being on top of the bumper in no time since I can not accelerate. 0-40 can take upwards of 30 seconds with pedal depressed full. Car was taken in for service at dealer in December 2017 and was "corrected". now the problem has become worse and car will produce problem more freqently and in any driving condition to include being in traffic. The only way I can somewhat correct the issues (and figured it out during trial and error) is to turn the drive mode to sport and turn off traction control. When car is in eco the problem is much more serve and in normal it frequently happens. I do not feel I should have to adjust or turn off systems in a vehicle to make it safe to drive nor should I have a vehicle I can not drive at safe speeds.

Engine stumbles when accelerator is pressed at low speeds, especially from a stop or turning a corner. I call it throttle lag or stumbling.

My new Santa Fe 2017 has a problem with the car not reacting to pressing the accelerator. Your press the accelerator and the car does not move and the engine does not rev. The hesitation is about 2 seconds long and is very scary. It happens intermittently and from a stopped position. I'm afraid at some point there will be a terrible accident from this problem. I've heard there is a recall 16-01-032 for the tcu update 60co61R1 but I reached out to dealership and they don't know anything about it. This is very dangerous and I did some research there are a lot of people having this same problem. I noticed this problary a week after purchase.

Car has serious, dangerous acceleration problems. It's most noticeable when turning left into oncoming traffic. Car appears to lose all power when accelerating - hanging for seconds while nothing happens. Engine hits redline all the time and it barely gains speed. Called dealer and was first told "dual clutch will learn driving style." After noting car has 2K miles was then told "the delay is a characteristic of that car." This is unacceptable and incredibly dangerous. I've almost been T-boned multiple times because of this. Googling led me to many other reports of the same issue. This vehicle needs to be recalled.

My wife and I have had the same intermittent problem since acquiring our 2017 Santa Fe brand new in the late spring of 2016. When turning from a stop or making a very low speed turn, and then starting to accelerate, the vehicle will stall and hesitate, not moving or "catching" for 1-2 seconds. This has happened to us approximately 6-8 times. And I've nearly been rear-ended on several of those occasions because I was stalled in front of traffic behind me, also trying to make the turn. Once I barely cleared the intersection at a light when turning left, having the Santa Fe stall in the face of oncoming traffic. I was nearly broadsided by swift moving, oncoming traffic. Someone is going to be killed if this problem is not fully addressed as soon as possible. The public needs protection and a remedy. I can't imagine Hyundai is unaware of this problem. I did a quick google search on the topic, and found many, many postings regarding this exact same set of circumstances. There were Hyundai message board complaints, NHTSA complaints, "lemon" law firms whoa are advertising, seeking potential 2017 Santa Fe owning clients, citing this exact set of facts. It's difficult to confirm exact dates, as this has occurred multiple times. The most recent time it happened was in early May 2017, at an intersection less than a mile from our home, making a left turn from a stop, with traffic lined up behind us.

Car hesitates to accelerate from a complete stop, accelerating while coming out of turn, or slowing down and accelerating again. Also seems to be using a lot of gas. Haven't calculated it yet but can see the fuel gauge lower as I'm driving. Car only has 17000 miles.

- Somerset, NJ, USA

The contact owns a 2017 Hyundai Santa Fe. While attempting to accelerate from a stop, the vehicle hesitated before accelerating. The failure occurred without warning. The dealer was unable to duplicate the failure. The dealer recommended that a fuel additive be added to the fuel tank, but that did not help. The failure recurred several times. The manufacturer was not made aware of the failure. The failure mileage was approximately 12,000.
