In february 2020, my check engine light came on after my car began to shake violently and lose speed as I drove on the city streets and highways.the serviceman replaced the coils in my car. Within a week, my car started to shake and lose speed again. I took it back to the dealership where they "fixed" it again to no avail. In early march, my car was still experiencing the same problems: shaking violently and losing speed as I drove on both the highway and on city streets. I chose to try a different service center. They attempted to find a problem with my car by running the codes, but he said that nothing popped up on the screen. I told him that my check engine light flashes on and off when I put my foot on and off of the accelerator. He sent me on my way without fixing my car, but he told me to bring my car back into the service center without shutting off my car as soon as the check engine light comes on the dashboard. He told me that this was important, because it would help them be able to detect the issue. Within 15 minutes of pulling off of the parking lot, my check engine light flashed back on and my car began to shake and lose speed again. I turned around immediately and took my car back. They flushed out the fuel line system. Within two weeks, I brought my car back for the same thing, but the serviceman told me that he could not find any issues since the computer showed no issues. Every time I take my car into a hyundai repair center, they tell me that they cannot detect any issues with my car, although I tell them that my car begins to shake and lose speed randomly. It is now sept. 2020, and I am still having the same issues. I am scheduled to take my car into a new hyundai service center in a new state. This is a dangerous car problem that threatens the safety of me and other drivers on the road. Hyundai needs to take action now!
2017 Hyundai Elantra acceleration complaints
Page 2 of 2: complaints 11 to 24 of 24, newest first, as owners wrote them.
Once again the car began to shake violently and started lunging forward while driving within city limits. Check engine warning light came on. I pulled over and shut the car off. When I restarted the car, the check engine light was no longer illuminated and the car seemed to drive somewhat normally. This was not the first time this happened, and from what I can tell by reading other similar complaints on the federal safety agency website, several people are having these issues as well. It appears to be the ECM, engine control module. Hyundai needs to address this issue asap. It is very dangerous to drive this vehicle. Do not allow them to say you need new spark plugs or a software update. This is a safety issue that needs a recall immediately.
The car cuts off while driving.it stalls n traffic like it won't go n I almost have been hit several times.there is no check engine light on.very dangerous n scares me when I drive cause u never know when it's going to cut off n traffic or while turning.
Vehicle is jerking, the car will accelerate fast enough, code p0190
I have a 2017 hyundai elantra. Started having problems with picking up speed rpms jumping and feeling like the car doesn't want to go. This started at 7,000 miles and I bought the car brand new off the lot it has been in over 8 times for this issue and have been told that nothing is wrong with the car or that because my car is not throwing check engine lights they wont fix it under warranty, or I'm not using a hyundai approved gas station so this is why I'm having problems with the car, now at 29,000 miles still having problems its the worst on the expressway in stop and go traffic.now I went to have my oil changed and found out I was low on 2 quarts of oil and my spark plugs have oil on them once again the car has to go back to the dealership, I was made fully aware of what could happen if the engine goes. I just really hope I'm not on the expressway when this happens, at the begin of the year I noticed when I would come to a stop my heat would drop and become luke warm it has now been into the dealership 3 times the thermostat has been replaced but I have been told that this is normal hyundai vehicles do this. My heat is dropping at least 58 degrees when idling and my window is having a hard time defrosting unless I'm driving.
Tl* the contact owns a 2017 hyundai elantra. The contact stated that while driving at various speeds, the brake pedal was depressed but was firm.

The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 75,000. The VIN was invalid.
While trying to increase speed to get on highway the RPM increased but my car would not speed up. Has happened on several occasions.
The car is slow accelerate like something is wrong with it. It started the year 2018. The care was purchased 2/17/17 with 25 miles on it. The dealer claims they can find nothing wrong.
"takata recal" the air bag light keeps turning on . Feel loss of power when driving speed limit under fourty-five also suddendley looses power when going the speedof seventy-seventy-five speed in the highway speed drops to fifty-five feels like it wants to stop. Afraid of getting hit from behind also hesitates when driving the speed limit under fourty-five feels like it wants to stop. Also the front wheel aligment light keeps turning on when ithecar is in motion and the airbag light also turns on when the car is in motion. These thing have been happening since april 2018 my car has only 41,ooo miles on it
Puchase my elantra in june 2017, when it rain or first thing in the am the brakes will make a sound like I need new breaks and like the rotor need replaced. I took it in and they said everything was find. One year later still have the same problem. The seatbelt light comes on and continues to beep with no one sitting in the seat and the only way I can get it to go off is to snap the seatbelt. Sometimes I have access to my bluetooth phone and sometimes it doesn't work or the display is not accessible
Tl* the contact owns a 2017 hyundai elantra. While driving at unknown speeds, the accelerator pedal was applied and traveled to the floorboard. The vehicle hesitated and stalled without warning. The vehicle was taken to cardinale way hyundai (2525 wardlow rd, corona, ca 92882), but the failure was unable to be duplicated. The vehicle was not diagnosed or repaired. Additionally, the vehicle was taken to riverside metro auto group (8330 indiana ave, riverside, ca 92504), but they were also unable to duplicate the failure.

3 occurrences: leave from parking space- turn on engine- wait until tachometer goes to 1- with foot on brake, shift into d- tachometer reaches 5 on speeding engine before able to turn off ignition. Driving very slow- with foot on brake- in forward to large parallel parking- speeds up- brakes spongy- does not stop car. Only high curb prevents car from climbing on sidewalk and giving me time to turn ignition off. Stopping at traffic light on road with a 35 mile speed zone. After stop, brake becomes spongy, car's wheels begin skidding- can only turn off ignition to stop the car. Everything back to normal when I turned ignition back on, as was the case with the first and second occurrences listed above. Vehicle was stationary in the first occurrence, was in motion in a park in the second occurrence and on a county road with a slight turn to the left in the third occurrence.
This vehicle accelerates more than expected (lunges) when I put it in drive and release the brake without even having my foot on accelerator. On flat surface it begins to move ahead spontaneously without my foot on gas peddle. I brought to dealer and they said this is typical for elantra and not a know issue. It has been mentioned by other driver's on reddit. The only solution is to have one foot on the brake and the other on accelerator to protect from sudden acceleration. There must be a software/hardware solution. Creates risky situation because one could inadvertently hit pedestrian, car in front at stop, roll into traffic, etc. Worst case would be if someone unfamiliar with vehicle drives it, ie, rental car or friend. I put in the date I had it checked by hyundai service. They said it might need to "break in" and tighten up as parts wears" as hopeful comments for resolution.
My vehicle has acc (adaptive cruise control) and, when set, will accelerate and brake as needed to keep a certain distance from the vehicle in front that the system has identified via the radar and camera. I had an instance where there was a momentary loss of positive control of the vehicle under certain conditions. In this event, it was a hazy afternoon with wet roads. I was following a vehicle on a road with the acc set. The vehicle in front started a deceleration less than 10mph/s and my vehicle automatically started progressively increasing braking action to maintain separation. 1.5 - 2 seconds following; it appeared as though the ABS kicked in and disconnected/overrode the acc witch subsequently stopped the braking action all together. As a result my vehicle proceeded torward the vehicle in front of me in a critical moment that required, now, even more braking action in conditions that initially caused the ABS system to activate under normal braking action controlled by the acc. I was aware and had not let the semi autonomous features of my vehicle lull me into complacency. I reacted quickly and a collision had not occered. Others may not be so quick to respond in a similar situation. I believe the system deactivated as a result of the ABS shaking the brake pedal or control linkages, where, in normal operation depressing the brake disconnects the acc if the system starts an unwanted acceleration or the operator simply wanted to disconnect the system without toggling the steering wheel disconnect switch. This feature is available on all limited ultimate 2017 hyundai elantras.
