My 2018 Hyundai sante fe was purchase 'certified' used from puente hills Hyundai in southern California. About a year into owning my car it began to jerk and felt like I went over a hard bump when I would accelerate from a stop and then began doing it while I would drive up hills. Puente hills Hyundai informed me there was a recall and that the recall would 'solve' the issue. After I got my car back, a few weeks later it started again. But happened less often then before. I recently took my car in and was told that puente hills Hyundai was able to recreate the jerking and would call the extended warranty company to have them come confirm the issue. When the warranty company finally came out, they unsuccessfully recreating the jerking sound and told Hyundai my car is 'safe' to drive and nothing is wrong with it. Hyundai tried to tell me to take the car back since there is nothing they can do to fix the issue since the warranty company said it was 'safe'. I refused to take it back due my safety and the safety of my unborn child and was told they would keep it again to see if they can recreate the jerking and then contact Hyundai directly to see if they'll come check it out. But wasn't guaranteed that they would fix and or be able to solve the issue. I have checked online and seen that several people owning this same make and model have similar complaints and have complained to you guys and was hoping that my complaint will be honored more than it has been at this dealership. The jerking motion happened when backing out of my drive way, accelerating from a stop sign, driving on the freeway, going up hill, or backing out of a parking stop and moving back into drive.

On the interstate, pressed the gas pedal and the vehicle did not and would not accelerate. I tried multiple times. RPM went up to 5000 but shifting the transmission into sports mode and downshifting and upshifting made no difference in the speed of the vehicle. Speed remained the same, engine roared as if in neutral. I pulled off the interstate, cut off the vehicle for several minutes, restarted the vehicle, returned to the interstate and could accelerate. This happened multiple times in 2017 and 2018 both on the highway and city streets. In 2018, taken to pearson Hyundai and could not be fixed because no error codes. After a dangerous, identical incident on the interstate in May 2019, taken to pearson Hyundai. They performed a tcu and ECU software update May 21, 2019. This latest incident is a repeat of the May 2019 problem. The problem is random and unpredictable but occurs on both highway and street speeds. The inability to accelerate without warning will eventually cause an accident. We also own a 2016 Santa Fe sport turbo AWD that has not had any of these acceleration problems. Changes were made in the 2017 model year to the engine and transmission that are impacting acceleration.

There has been some engine noise for 2 months or so.. I then had an oil leak and the dealer said that the engine noise was from crankshaft and maybe a bearing inside. I have 74, 000 miles on vehicle and have a 10 year 125000 mile extended warranty. I was at the dealer today and they gave me the news about maybe crankshaft bearing. The Hyundai motor company has a recall on your site about 2017 Hyundai Santa Fe having defect in a pin in the crankshaft that wears the bearing. This seems like exactly what dealer is telling me. My question is, the recall says that Hyundai motor company recalled 420 2017 Hyundai Santa Fe's that were produced between January 26 2017 and February 13 2017. My Santa Fe was actually produced on January 14 2017, which is only 12 days prior to the start of the official recall production date of January 26. How does Hyundai motor company know that my vehicle was not produced with this faulty pin in the crankshaft that causes bearing failure? thank you very much for this website and I hope someone can enlighten me as to what I may be able to do right now.

When I drive going straight at about 40 to 48 mph on eco mode or any drive mode the car jumps/ jerks like it shifts into a low gear and then goes back into a high gear with no heavy acceleration. If I have it on cruise control at 45mph it will kick back and forth occasionally as if I was slamming on the gas pedal then slightly on the break but quickly.

- Pingree Grove, IL, USA

When the vehicle is stopped, and when starting to accelerate, there are times when I'll experience a 1-2 second delay or hesitation, before the engine/transmission engage. This seems to occur mostly when the wheels are in a turned position. It can be a frightening experience at an intersection, with no power. This has occurred approximately a dozen times.

I purchased a used 2017 Santa Fe AWD on 11/06/2019. The car failed to start on the first attempt at a gas station -- the first time it has happened after purchasing the car. It started on the second attempt, the car drove smoothly to the dmv for registration. About 1-2 hours of driving, the car stalled in town despite accelerating with rpms greater 3. the car became responsive only after stopping and restarting at the curb. I noticed a steady check engine light on the dashboard for the first time after the incident and have been having a jerky ride experience ever since. A call to bluelink confirmed that the car requires a thorough system check involving the power train at the dealership. An appointment has been for 12/4/2019 and the car has been parked.

There is a few seconds of hesitation when trying to accelerate at times. From a dead stop or a slow roll when turning, the car will move in slow motion only and the anti slip indicator comes on like you are on a slippery surface even when it's dry. Then it accelerates suddenly. We have come close to having several accidents because of this. We have taken our vehicle in over 5 times and the service departments at two dealerships say they cannot replicate it and brush us off. This is a huge issue and needs to be addressed before someone gets killed.

On March, 19 2019 around 5:00am I was on my way to work like normal. As I was getting on the 60 freeway at about 45 miles per hour my car shut off while driving. I had no power steering but I coasted to a stop in the right lane of freeway turned my car back on and drove about 500 feet and the same thing happen but this time it would not turn back on.

I was making a left turn on to a street going uphill and my 2017 Hyundai sante fe sport AWD ultimate hesitated for approximately 10 seconds. When I pressed the gas I could not get speed. My traction lights blinked on and off. I had to floor the gas to gain speed. This is extremely dangerous. I could have been T- boned or hit from behind if there was traffic on the street.

While I am driving and my car is changing gears, it does fine until its in fourth gear. The RPM will go to about 2,800 until it changes to fifth gear. Onve its in 5th gear the RPM will go into a "neutral" state and rev from 4,700 RPM to 5,700 without any acceleration. This happens when accelerating up a freeway entrance. I have been to the dealership 3X now and all they keep saying is the transmission needs an update. And the adaptive values need to be re- learned. I have now had my transmission fluid filled once and then I paid to get a tranny flush. And adadptive values reset twice. Nothing has changed. I have 38,000 miles and this has been going on for about the last 15,000 miles.

I parked my car parallel to the curb on a city street. I moved the shifter from "drive" to "park". I did not turn off the engine because I was only going to get out for a few seconds to open the door behind me to let some senior citizens to get in the car. I released my seat belt buckle and proceed to open the driver-side car door. As soon as my feet were on the ground and my body was outside of the car, the car started to move in reverse direction. The car was moving fairly quickly because within a split second, I was knocked to the ground by the car door with the left front wheel on top of my left foot. The wheel proceeded to roll over my left ankle, leg, thigh, hip, abdomen, chest, and finally my right upper arm and shoulder joint. The car continued to travel in reverse by jumping the curb onto the side walk and finally stopped by heavy bushes in front of a building. Upon inspection, the shifter had slipped into the "reverse" position. Based on the gradient of the road service with the engine running, the removal of my foot on the brake would have immediately allowed the car to move backward had the shifter was in reverse which would make exiting my whole body out of the car without noticing car movement very unlikely if not impossible, particularly for a 72 year old male who is recovering from an open heart surgery and two brain surgeries. The shifting mechanism and the associated control must be faulty resulting in the "false park" position.

My 2017 Hyundai Santa Fe hesitates when accelerating. Can be very dangerous when avoiding traffic or moving through traffic.

I had my car for 12 months I bought bran new. It has staled and turn off on me at least 5 times. This is a safety issue especially on the freeway the car loses power and stops.than before it stops makes a knocking noise.

- Bakersfield, CA, 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).

- Plymouth, MN, USA

Severe hesitation when coming out of a sharp turn. Also happens upon acceleration after a traffic light. Happening more frequently as time goes on currently 13K miles on vehicle. Happens almost every driving trip but put todays date on it as it happened last today 8/1/18.

- Joliet, IL, USA

Failure to accelerate from a stop position. Pulled off the highway onto the off ramp. Came to a stop then tried to turn left. Vehicle barely moved and had to accelerate to over 2500 RPM and several seconds later to get the vehicle barely moving. Pulled off the road, put the vehicle into manual shift mode to find the transmission is locked into 4th gear and cannot be downshifted to 1st. Vehicle continued to be locked into 4th gear after each stop. Turning off the vehicle and restarting temporarily corrects the problem. Potential major safety issue. Vehicle now with dealer to resolve

- Lake Wales, FL, USA

Vehicle has intermittent starting issues similar to a low or dead battery. Will only start when it wants. Usually happens at first start of the day or late afternoon. Putting vehicle in drive is harder than normal. Transmission gear shifts have hard jerking feel.
