- Pleasant Valley, NY, USA

The vehicle shifts extremely hard from a stop and when in lower gears in motion. You push the accelerator to go and it slowly responds and then it shifts violently sounding like something fell off the bottom of vehicle and jerks the whole vehicle and passengers inside. Vehicles behind us come very close to hitting us when this occurs and the vehicle has not moved yet as normally expected.

My car wouldn't start had my car for service. I was charged a service fee which they would tell me whats wrong with the car. I was only told the battery was an issue. That was replace. The person who attend me did not tell me anything about getting an oil change or any other problems in February. Went back in April because my car stop running turned off in the middle of the road. Went back to the same dealer I not fix cars so when I get servive for the vehicle. I would think someone would tell me otherwise but no. I toke it back I was told the vehicle doesnt have warranty. That it expired but in the system there was no warranty even recorded. Now I am stuck with harassment calls about a vehicle I no longer have due to lack of maintenance. I purchase the vehicle last year in June 2019. I didnt have the car for then a year.

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.

The contact's client owns a 2017 Hyundai Santa Fe. The contact was a lawyer and stated that his client's vehicle stalled. The client attempted to merge onto the highway, but could not enter the onramp because the vehicle stalled. The vehicle was immediately pulled over to the road shoulder. There were no warning indicators illuminated. The vehicle was taken to danbury Hyundai (102 federal rd, danbury, ct 06810, (203) 730-4700) to be diagnosed, but no failure was found. The contact did not know if his client's vehicle was repaired because the mechanic did not provide a straight answer. The contact's client was instructed by the lawyer not to retrieve the vehicle until there was confirmation that the vehicle was repaired. The manufacturer was made aware of the failure and a case manager was assigned. The VIN was unknown. The failure mileage was 10,000.

- Newtown, CT, USA

Engine starting making a knocking noise. Brought into dealer and was told it had complete engine failure due to broken bearing and I would need a new engine. Denied request through warranty. Only around 43000 miles are on the car. Hyundai informed me it was denied due to oil not being changed properly as evidenced by two areas of sludge on the inside of the hood of the engine. Service records brought to Hyundai showing oil was changed within the 7500 mile as indicated on Hyundai's website and owners manuel.

Carbon monoxide inside the cabin when traveling on the freeway about 70 miles an hour

- Laguna Niguel, CA, USA

Car completely shut down while driving at a slow speed turning right from a stop sign, was lucky to be able to pull over to side of road. All electrical/computer shut down, engine cut off. Restarted but engine sputters, feels like it is trying to shift gears while still in park. It was a very unsafe situation. Was not able to get started to drive home. One week earlier I noticed the computer acting up when I first started up, but restated and drove anyway (no problem that time while driving).

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

- Chicago, IL, USA

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.

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.

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 vehicle from time to time about once a week stalls while accelerating, it happened so far while doing a left turn on local streets. This is very dangerous and can cause an accident

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.
