2017 Hyundai sante fe SE, when first purchased I felt hesitation, according to dealer they was a update for the computer, I took it in for update which actually did not make a difference. At times when getting in vehicle to drive off and put in gear it would not move. Took to dealer for service tech drove car home and stated that there was no issues. After that I stopped using vehicle. I sent Hyundai Consumer Affairs a complaint and they brushed it off. Since I didnt buy the vehicle at the dealer I took for service they could not give me a loner. Suspension has a defect changed tires at 15000 miles due to humming from rear, had vehicle aligned and new tires 6 months later tires are worn Hyundai has suspension issues. Last, so far is engine knocks when starting vehicle. Its a shame that we have to make payments on vehicle that dont serve our needs and Hyundai does not care but to have there payments on time. I contacted my attorney, planning to drop off at dealer and return to Hyundai so the finance company can take it back either I get my issues fixed just like everybody else should or I stop paying and take it back. If you anybody that is interested in buying a Hyundai vehicle like ours send them elsewhere.

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.

9/18/17 while driving on highway at 65 mph the ABS light came on and the vehicle while trying to accelerate moved slow as if to not want to shift. I got to the side of the freeway and turned the vehicle off and when I re started a few minuets later the light went out and vehicle operated without out problem. I made appointment with dealership for 9/26/17. They did some recall items and I mentioned the problem and was told if the light is out it may not show up. The failed to not on service order this issue. On 10/24/17 while driving on freeway and had traveled about 50 miles from home the ABS light came on again and this time it notified me on the radio screen to contact blue link as there was a possible condition with the brake system. I contacted blue link and they made an appointment for 10/27/17 at 8 am at the dealership. After 6 hours waiting on Hyundai tech support to get back with them to run diagnostics. Last 3 months vehicle monthly report on vehicle shows a problem with the ABS system. They claim they are unaware of any issues.10/24/17

I purchased a brand new 2017 Hyundai Santa Fe limited ultimate on May 5 of this year, and noticed a very hesitation during the drive home from the dealership. I figured it was the result of the engine breaking in and that I should just be patient. However, it continued...and progressively got worse. Specifically, it's most pronounced when I accelerate from a dead stop, accelerate out of a rolling stop, accelerate out of a left turn, or try to make a quick passing or merging maneuver on the freeway. In all of these conditions, there is a 2 to 3 second delay before the transmission will suddenly downshift and the vehicle will blast off. This is really dangerous, because I've had nearly a dozen instances of being nearly rear ended because the vehicle won't accelerate quickly enough. The best way to describe it is to say that it's like trying to accelerate with a dirty, severely clogged, 10-year-old engine air filter, and the intake can't get enough air into the engine to accelerate as it should. I've been to our local dealership several times about this issue and in every instance we're told that there is nothing they can do until Hyundai releases an update or a recall. But in the meantime, I guess I'm supposed to continue playing russian roulette with my life. I'm at nearly 9,000 miles and the hesitation is still as pronounced as it was in the beginning. I'm trying really hard to be patient and not keep complaining to our local service center...but we've had quite a few close calls, extremely close, and I'm really hoping that Hyundai will please fix this soon! in fact, I just read an article about Hyundai replacing the engines in the '17 Santa Fe's because of a manufacturing issue with the crankshaft pin causing the exact same symptoms I've experienced. So I hope that I can please get my vehicle repaired before I end up in a terrible accident. Thanks!!

The contact owns a 2017 Hyundai Santa Fe. While the vehicle was parked with the engine running and the gear in park, the gear automatically shifted into reverse and the vehicle moved backwards. The failure occurred without warning. The contact was standing on the passenger side with the passenger door open. The contact jumped into the vehicle and applied the brakes in order to stop the vehicle. The contact was able to stop the vehicle and pulled over to the side of the parking lot. The contact turned off and restarted the engine, and the vehicle returned to normal. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 23,300.

Had this Santa Fe for a little over a year. I have noticed several instances of not being able to accelerate, or gain speed, especially when turning or starting from a stopped position, it hesitates to start to the point of almost being hit several times. I have taken it to dealer many times, and they keep telling me its the way I am driving it that the engine is like a standard vehicle, but that doesnt seem safe to me if I am trying to start driving and it wont go. When it does finally decide to go, it takes off way too fast and is like, it finally decides to shift into gear. Also while in park, engine revs to 2500rpm for no reason or idols at that RPM. It feels like the engine is pulling the car forward even when it is in park I have been given the run around so many times, I am tired of it. I'm not happy to see others have this issue, but I am also glad that others are experiencing the same problems.

2017 Hyundai sante fe sport AWD - purchased in Oct 2017. Currently have 7525 miles on vehicle. I noticed acceleration hesitation immediately after making in city turns (from both stationary and in motion turns) as well as when getting on highway (in motion). I am retired and do not drive sante fe very often. The problems with acceleration after making stationary and in motion turns and getting on highway has always been present since day of purchase. I have noticed the problem has become more prevalent after taking a 1000 mile road trip this past August. The acceleration/ hesitation after turning is more noticeable and is becoming concerning because I have to press petal to floor to get the sante fe to accelerate properly to get out of way of on coming traffic. Hesitations/acceleration problems occurs after turning and when entering a freeway. Very poor engine performance given the vehicle cost of $35,000. I owned a 2011 Hyundai sonta for 6 years and had the same 2.4L engine and I never experienced any engine hesitation like I am now with the 2017 Hyundai sante fe sport AWD.

Multiple times while attempting to accelerate the rpms will go up and the car does not move. When it finally goes the car will jerk and the rpms fall. There seems to be a loss of power when this happens. Also seems to happen when making left hand turns across traffic, which can become dangerous with oncoming cars. This happens when attempting to accelerate.

- Kansas City, MO, USA

At stop when turning right are left and accelerating the transmission fails to respond ad the car stalls then will go. If slow to slow speed and accelerated the car will stall before shifting down. This problem is a safety hazard. Took it to hyuandi dealer at 3000 miles was told it was normal.

- Alma, AR, USA

Severe hesitation when trying to accelerate from a stop. Occurs intermittently and happens when turning right or left. More likely to happen if road surface is rough that vehicle is turning onto. The vehicle will begin to accelerate and then lose acceleration. Although pressing the accelerator the car does not speed up even though the engine revs up. After about 3 or 4 seconds the vehicle then responds and begins to accelerate. This situation does not occur all the time. It may occur 3 or 4 times in a week. This is a safety concern because I have almost been hit from behind as a result of the vehicle not accelerating.

- Wilmington, DE, USA

Have owned vehicle since 12/16. Approx 6 times there has been an acceleration problem when changing lanes or turning. Have pushed the gas and nothing happened - engine does not rev or respond in any way to the pressing of the gas pedal. Its like the car is in neutral and then it will just all of a sudden re-engage. No warning lights; no indication when it will happen. Filed complaint with Hyundai but they are unable to recreate the problem and/or will not assist until they can. Dealer had car for two weeks and could not recreate so Hyundai closed our complaint. The date entered below is the last time it happened.

Hesitation when entering traffic--hair raising experience--there is a 3 to 4 second stop in the in the drive train--the control of the vehicle is gone-leaving one in a panic mode--also feathering the throttle at times there is no response--took SUV to dealer--they hooked up a monitor and with the service manager on board--- the vehcle did not respond when accelerating--I am told due to the information sent back through monitoring to the factory that the dealership could not ask for a buy back--my question is how can a co keep making and selling a unit that is defective ?--there are hundreds if not more similar cases on line with the same problems--I will not drive this vehicle on road--life threatening--if the dealership or co. Does not agree to buy back I will be forced to take further action--stand by--class action may be on its way!!!my case is pending--awaiting a response by either dealership or co.hope some one is far minded as to this continuing problem--after all this is the U.S.a

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.

2017 Santa Fe sport with turbo.when turning left into traffic from a stop or near stop, the acceleration studders or doesn't respond, it acts as though it isn't engaging the gears in the transmission. Very dangerous when trying to enter traffic, you start to roll, like you are releasing a clutch in a manual transmission, but it doesn't accelerate until you are committed to the turn. I noticed one time that the anti-skid traction indicator flashed, but I haven't looked each time. I haven't noticed the delay going right, but left it happens nearly every time. We have come close to being hit twice now. I called the dealership that we bought it at and they said that it could be the adaptive learning that needs to be reset. The vehicle learns from the driver and resetting it would cause it to learn over again. We have an appt to have it looked at and duplicate for them.

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.

When making a right, left, or U turn the power completely cuts out and the car is left drifting without power. Their is no response to pushing on the gas peddle when this happens. At the same time on the dash the orange traction control light comes on. This last for a number of seconds and then the engine starts to once again respond to the gas peddle. This problem has happened to me and my wife12 times since we purchased the car 3-1/2 months ago. The problem has occurred in all weather conditions from a standing start and a rolling yield or U turn. The problem has always occurred on a paved public, city/county, street I have had the car to two different dealers, one several times, and both tell me that their are "no codes showing" so that their is nothing that they can do. You have to experience the fright of loosing power while you're in the process of a right or left hand turn with traffic coming at you from one or both sides to appreciate how truly dangerous this car is. This is our 4th or 5th Santa Fe, up to now all of them have been great but I am afraid to drive this new car we have now.
