The contact owns a 2017 Hyundai Santa Fe. While driving, the engine stalled without warning. The dealer and manufacturer were not notified. The vehicle was not diagnosed or repaired. The approximate failure mileage was 9,000.

Car leased in Feb. 2017. Just after finalized, noticed this serious problem: The acceleration after a turn is extremely slow and takes an unreasonable amount of time causing danger of vehicle behind slamming into back end. Upon accelerating after a turn there is so much hesitation that it caused driver and passengers to lunge forward once the engine kicks in. The light indicating slipping usually comes on when this happens as well. My son drove it today with my younger boy and they were almost rear ended. I've talked to dealer twice about this.

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.

The vehicle fails to accelerate past the initial press of the accelerator from a stop leaving you committed in traffic without power for around 2 seconds. Stepping on the accelerator fails to produce any power. Just had the vehicle looked at by Hyundai who said they can find nothing wrong. Hyundai also said there are no bulletins or recalls. A search on the internet shows an alarming amount of chatter from other owners with the same issue. There is under 6000 miles on the vehicle and this has happened numerous times, intermittently.

Engine stalled (died) when attempting to cross 3 lanes of traffic. This occurred 2 times when on vacation. Vehicle was returned to dealer for service. Dealer had vehicle for over a month and said they couldn't duplicate problem. During this time there was a national recall issued by Hyundai for Santa Fe. I thought are problems would be solved. But was informed that the recall only covered upto production year 2015. We received a 2017 Santa Fe loaner for use during the time they assessed our vehicle, this vehicle also stalled. I reported this to the service Mar. He said he couldn't do anything until Hyundai authorized a recall for 2017. I told him that they probably won't until they sold off all their new vehicle inventory. We took our vehicle home. 1 day later the vehicle stalled when my wife pulled out on to a busy highway. These vehicles are a significant safety hazard.

2017 Santa Fe ultimate 2.0T. Car does not accelerate and lags. Happens at a lower speed and from a stop. Very scary when making a left turn and entering freeway.depressing accelerator and nothing happens for a second or more, then all of a sudden it takes off. At low speed in parking lot depress accelerator lightly and car takes off. When accelerating from a stop car will accelerate quickly while depressing pedal gently. Does not happen every time but is frequent enough to be concerned. Has happened since new.

Sometimes, when I press the gas to accelerate, my car does not go. It will move forward at a slow pace but then doesn't go as fast as I'm pressing the gas pedal, even though my rpms are increasing. This has almost caused an accident because the car does not perform as it should. Happened today for probably the 10th time since I've had the car, less than a month. Pulling out of a parking lot onto the street, my car move's forward very slowly then when I go to increase my speed the car doesn't go faster.

Hit pot hole after stop and stability control stops power to transmission...5-8 seconds of no accelaration has caused safety issue when merging into traffic. Appears to be a very common problem on user based forums.

- Morrisville, VT, USA

When accelerating out of a very low speed turn (such as turning at an intersection or pulling out of a parking lot into a roadway) the engine suffers a complete loss of power for 1-2 seconds. It does not happen all of the time. But frequently enough to make one worry about pulling out into traffic.

The Santa Fe sport turbo engine severely hesitates to accelerate when coming out of turns or roundabouts to the point where I was almost rear ended! when the engine catches up, it jerks your head back. The other day was the worst when I entered a parking garage with an incline. Upon acceleration, the engine hesitated to the point I almost started rolling backwards. When it finally kicked in, the car surged forward as if the acceleration pedal was floored. A pedestrian literally jumped out of the way thinking my car was going to hit him. This engine is a safety issue!

I have a 2017 Hyundai Santa Fe ultimate and like the other complaints, the car has hesitation when trying to accelerate especially after a stop, bump in road, slowing down, etc. The dealership has had the car several times trying different things such as try a different mode, reset transmission computer, etc. I've called Hyundai customer service and filed a compliant open but I don't want the car anymore it hesitates too long/too many times and scares the crap out of me. It's dangerous and needs a recalled.

When driving suddenly the car decelerates making it necessary to mash harder on the gas pedal to get the car to continue moving. The usb port does not charge which results in the phone losing battery life you can only use android and apple car onn that port so when traveling long distances you may be without directions. Its an ongoing issue.

Engine stalling at slow speeds. Further, at slow speeds, there is a significant delay of several seconds for power delivery. For example, if driving slowly, say at 5 mph, and power is needed immediately (such as in an emergency or a lane change situation), nothing happens for over 3 seconds when the accelerator pedal is depressed, followed by a dangerous lurch when power is delivered suddenly. This is a highly dangerous and unacceptable condition. I spoke to the dealer, who dismissed my complaint and claimed that "all cars are the same these days". this is a regular problem that occurs multiple times every day.

Two issues: Severe problem - when driving at a rate of approximately 35mph today on a major city thoroughfare, our 2017 Hyundai Santa Fe 2.0T ultimate suffered a sudden and complete loss of power (engine and all electrical systems including lighting). After coming to a stop, the vehicle was stranded in place until it was able to start up again many minutes later. Fortunately no one was physically harmed as the individual driving behind our vehicle was observant enough to identify the issue (despite a lack of brake lights or hazards) and stop in time. No visible engine light or fault code was triggered. Less severe problem: On a regular basis, the vehicle suffers abrupt and sustained loss of power in merging situations (especially when turning on city streets from a stop). This seems to be from an overactive or otherwise ineffective traction control system/programming. Despite even planning for the possible loss of power, this has still resulted in a number of "near miss" situations. A warranty visit has been scheduled for these issue and we will gladly provide the results and/or other updates upon request. We are, however, seriously considering selling the vehicle at a loss due to these two issues.

The 2017 Hyundai Santa Fe limited will bog down when starting from a stopped or low speed while trying to merge into traffic or turning. There is a significant hesitation - almost to the point of stopping while merging - very significant safety issue. Been an ongoing problem since bought 5/31/16

We bought a 2017 Santa Fe sport with the 2.0 T engine in July of 2017. It has about 5,000 miles on it and has now started to hesitate badly when trying to accelerate when turning. It seems as though it either loses power or the transmission is not in the correct gear. The result is a very dangerous situation when try to turn onto a road with traffic. We are going to call the dealership were we purchased the car to see if there is any fix. I see from other complaints this is turning out to be a common issue.

Engine stalls at any speeds while driving. Tech at dealership could not find the problem. Dealership stated they never had a problem like this before. The engine is a 2.0T which was subject to recalls for the same problem. Hyundai currently settling class action suit for Hyundai sonatas with the same problem in model years 2011-2014 2.0T engines. Speeds when occurring 40-65 mph. Eleven incidents so far since purchasing the vehicle 4/8/2016.

Sometimes after slowing to make a turn the car's engine seems to "stumble" for a second before acceleration can begin. Comes as a surprise and because of the hesitation catching me off-guard I am pitched forward in my seat. Nothing catastrophic, but very annoying and could be dangerous to a driver not knowledgeable about this problem. This is a brand new car and I noticed this problem after only a day or two of ownership. I suspect this is a software issue and can be fixed with a reflash of the ECU, but that's just my best guess. Have not contacted the dealership yet, but thought I'd file this complaint first to see if a recall can be issued to fix this problem.
