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.

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.

From stop, or near stop, engine cuts out (stumbles) during normal acceleration.

I bought the vehicle on 5/7/16. On 6/2/16 I was driving on highway 395 when I noticed smoke coming out of the engine compartment. The car started losing power and eventually died. When I got it pulled over to the side of the road I noticed flames coming out from the front of the engine. I grabbed what I could and got out of the car. Within 5 min the front of the car was engulfed in flames. I had approximately 675 miles on it. I have contacted Hyundai but they have not responded to me. I ordered a copy of the police report but have not received it yet. I have pictures that I have attached. I am concerned about this happening to other people. Thankfully I didn't have grandkids in the car, I'm not sure I would have been able to get them out.
