general problems of the 2017 Hyundai Elantra - part 1

The vehicle has experienced ongoing powertrain and electrical malfunctions over several months. The most common symptoms include being stuck in 4th gear (limp mode), complete loss of rpm and speedometer readings, and illumination of the check engine and esc lights. Most recently, while traveling at approximately 10 mph, the vehicle experienced a sudden loss of both acceleration and braking. The brake pedal became stiff and unresponsive, and the car had to coast to a stop without driver control. This posed a serious safety risk to myself and nearby traffic. These issues have persisted across multiple service visits to ricart Hyundai in groveport, ohio. That dealership has replaced the crankshaft position sensor three times, the powertrain control module (pcm), and the battery, but the underlying problems remain unresolved. A technician at the dealership was able to reproduce the stalling event during a test drive. Despite that, the dealership has refused to proceed with further diagnostics unless I pay for an oil change, even though previous inspections by their own staff found no visible leaks and confirmed the oil level was sufficient at the time. They have also revoked complimentary access to a loaner vehicle despite the unresolved and unsafe condition of the car. The vehicle remains available for inspection. The problem has been confirmed by a dealership, has occurred repeatedly, and continues to pose a safety concern. Warning lights and gauge failures typically appear when the issue occurs.

My auto has a problem with the brake light on the drivers side not working at some times. The issue seems to happen almost every 6 months or so. The first time it stopped working, I took my auto to the dealership where I purchased it from costing me about $65. 00, the second time 6 months later the brake light went out again. The bulb was replaced by the dealership at no charge, I was told that the bulb was put in wrong. The brake light is now out again. I noticed that it may come on but when I press the brake pedal and release the emergency brake, it goes out and stays out until I shut the auto off for a long period of time. Often it will be on when I'm driving and then it goes out.

My vehicle was towed to manly Hyundai in santa rosa CA June 18,2025. The vehicle when driving steered all over the lane then locked up on me almost causing a crash. The dealership says it’s the electrical column assembly. My vehicle is a 2017 Hyundai Elantra but don’t see any recall on it and I am being charged $3400. 00. The red steering wheel light went on . I’m looking for a recall on this vehicle seems many others have had the same issue. I do not have any receipts yet since it was towed and parts are being ordered and work will start this week. As soon as I have paperwork I can forward it to you. Thanks for your help in advance. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Constant misfire issue causes vehicle fo completely bog down while driving. .

Hi the Smart junction box on this vehicle is acting up. When riding in free way all doors locked open automatically and then the headlights just went off, and all the 4 blinkers stopped working creating hazard to all people in the freeway including mine . Mechanic has quoted me 2k to fix the issue and replace the Smart junction box . Please provide me fairness in this matter.

Power windows stop working, car cuts off, heated seats stop working intermittently.

My steering wheel locks up on me and the my check engine light flashes on as it does. I also have a steering wheel light with an explanation point beside it flashes when and before my steering wheel locks up! I can be sitting at a red light and my steering wheel locks up on me. My traction control light is also on and will not turn off. It turned on when my steering wheel locked up and my steering wheel icon came on.

When car is unlocked the drivers door will not open until you pull 3 times. Now the passenger door will not open at all from the outside. You have to open door inside car and push door open.

Without any warning lamps coming on, the vehicle car stalled while driving on the highway. It randomly stalls constantly when turning corners, especially on left turns (odd?). The scariest thing that happened was it got stuck on the speed limit of 55-60 miles per hour and I couldn't brake or accelerate. This put my kids, other drivers, and my life at risk. On father’s day, while my husband was out with the kids the vehicle tried to accelerate on its own when he was at a stop. It happened multiple times as he tried to make it home. Then when he was in stop and go traffic, it got difficult for him to brake. The brakes started failing. What more can I say?.

Since January 2024 I have had issues with my car starting due to low oil. I just had an oil change so I knew something was wrong. The repair shop stated there were no leaks and put more oil in and said that sometimes the car will not start if there is not enough oil. February 2024 and the car wont start again. Filled it with oil and took it to the shop again. They stated that the engine is eating the oil and to take it to the dealer for a test. Since then the car has turned off multiple time both while idling and while on the freeway. When you hit the gas it will not accelerate either. In the past I was able to turn the car off and back on again and it would work just fine but now it seems more frequent. Also, while driving when experiencing these issues I have had the stereo screen shut off and restarted by itself. At times the slippery when wet alert will also show on the dashboard which has been a sign for me that they car is going to act up so I turn it off right away and back on then it runs.

The door handle doesn’t open from the outside, causing you to open from the inside.

Rear passenger door does not open.

Car will lose power and quit suddenly on the highway with no warning lights. It has happened twice in the last month on a trip both times. Light’s low beam randomly won’t turn on either but high beams work. Had it into the Hyundai dealership and another mechanic shop but cannot find the problem.

My two back doors will not open they just opening.

When driving about a month ago my car all the sudden started making a clinking noise not so much knocking in the engine or near the engine. And then it died all the sudden at a red light out of no where. Well I put the car into park and started my car again when I accelerate the rpm takes a lot longer to catch up to the speed I'm trying to go, so it takes longer to accelerate which is dangerous because cars usually accelerate alot faster than that and I almost got rear ended twice because of it. I parked it for a few days but moved recently so I had to move the car it started and everything but the knocking, or clinking was still there. The following day I went to start my car and know it won't even start and the anti theft light comes on, on my dash board. So now my car is stuck at a motel because of it. I think it may be the crank shaft position sensor. Yes my vehicle is available for inspection upon request. No my vehicle has not gotten in any accidents. It has not been inspected by a manufacturer.

My car has been dying while on the road when I'm slowing down. I have spent $2,700 to get this issue fixed, and after replacing everything the computer said was wrong, the auto shop has determined that the issue is, in fact, the computer itself. There is nothing left to fix, but the car still will completely shut down while driving. Not safe at all, especially since I live in a high traffic area. There are no warning signs before the car shuts down, but lights do show up on the dash when it has shut down. The check engine light, oil light, and battery light come on.

After driving the vehicle at night and turning the engine off certain exterior lighting components would not shut off. Turn signals and reverse lights and brake lamps we stuck in a static on position even when not being activate by turn signal switch or brake pedal being depressed.

The doors will randomly stop working intermittently causing passengers to be stuck in the vehicle and in the event of an emergency making it difficult to safely exit the vehicle. The vehicle while in motion the engine would not function probably and would be flashing different engine light but never a code and the engine would stop.

While at red lights, coasting or waiting in drive-thru the car starts jerking and shaking. Will stall and fail to accelerate, sometimes coming a complete stop. Turning on and off the vehicle only works some of the time. This started in 2020 and went on for months while Hyundai kept "fixing" the car. Coils were replaced in 2020. Now again in 2023, exact same issue. On 9/29/23 car starting jerking while waiting at red light, turning car on and off worked. On 10/1/2023 car starting jerking and shaking while waiting in a drive thru, this time it did not stop no matter how many times I turned my car on and off. They are trying to tell me this is wear and tear on my part. Car is no longer drivable since you never know when this issue will happen.

I was downhill turning right. My vehicle turned off. I started it and it turned off again. Happened again. Turned it back on and was able to continue to drive. Luckily for me there was no other vehicles on the road but could have caused an accident if car was behind me. I am planning on making appointment to take to dealer. No warning signs, engine light flashed on when car turned off but that's it.

The car randomly dies on DE-acceleration. It gives no warning and I have seen online this is a known issue with this year/model. I have 55,000 miles on it, it's been regularly serviced. When I got to slow down then start to accelerate it shuts off. I've nearly been hit multiple times going to merge from a stop. It's very dangerous. I've replaced all 4 spark plugs, all 4 ignition coils, air filter, cabin filter, oil filter, pcv valve and I've only owned it 6 months. No engine light comes on and no reader is picking up any codes. I'm at a loss as to what causes this.

Check engine light on transmission sensor is wack car slugs and knocks. This car also has the white paint defect! this is my first and last Hyundai, go to accelerate onto interstate but can barely get the car to go past 30mph.

The power steering went out as I was driving with my infant in the car. I was making a turn and it completely went out. That is very dangerous.

Vehicle would do a complete stop without warning while driving. No, engine light isn’t reflected on dashboard of 2017 Hyundai Elantra, went into a complete stop on hwy. Had vehicle checked everything looked good, hidden problems couldn’t be resolved dealing with matter that could have been deadly if traffic were to occur.

The car doors on my Hyundai Elantra often have jammed frequently jammed the front door was repaired when a few weeks later the back driver side door also jammed and could not be opened from the outside unless you pushed in and pulled out. Then it finally jammed altogether and would not open . If there were an incident and someone needed to get into the car to get my child out they would be unable to.

My car was serviced according to the recall sent by Hyundai to install anti-theft security software to my vehicle. My car was locked, broken into, and stolen with the installed security 3 months later. The attached summary outlines the details of the car as it was purchased, recalled, stolen, and recovered, with pictures of the damage included. The Hyundai recall software was not installed correctly or is not effective at preventing vehicle theft for automobiles without immobilizers.

For a little over a year now, my back doors do not open on my Hyundai Elantra. The child lock is not on. Also in the past year, my passenger and driver door do not open. I have to go back and forth on the handle 20-30 times before my door opens. I have changed the battery in the key fob and I have tried unlocking my doors with the actual key with no success. Sometimes if they do not open I have to go through my sunroof. This is such a safety issue it’s insane. I’ve called Hyundai dealerships but they said they will need to keep it for 2 weeks. I do not have any other vehicle to just leave it there for that long. Please help.

When coming to a stop, turn or sometimes when driving throttle goes to zero, oil, engine, and battery light come on and gas peddle no longer works (car no longer accelerates) . Have to turn car all the way off and restart it and it runs fine (all lights turn off and car accelerates) until coming to a stop again (the same exact thing happens). Went to trade it in as soon as person test drove it he almost crashed because the engine stalled again. This has been happening for months but progressively worsened (happens very often now almost causing crashes).

I received a mailer and text with my VIN stating I had the 993 recall for my anti-theft software in March. I made an appointment beginning of April for may1st for the recall, after going to the dealership I was informed the recall did not exist and the mailer was wrong. After calling Hyundai service I was informed that an appointment could be made to fix it and then after another call to Hyundai I was informed that the recall did not apply to my car, also during this call the lady told me that I can just buy a wheel lock to fix the issue.

My 2017 Hyundai Elantra that I got in 2020, has been shaking at idle for 3 years now off and on. I even got it serviced at Hyundai in tyler TX under warranty. I was told it’s the coil packs. I was driving to work yesterday and the engine light was flashing at me, and my car was shaking and knocking extremely bad. I had to turn around and miss work due to this issue. Although, when I go to nearest dealership there are no obd 2 codes that populate, or any codes for that matter, but I’m still seeing the engine light flashing, and I’m still experiencing daily shaking and knocking of my car at low speeds, and even on the highway. I’m scared to drive it since nobody can find codes as to why this is happening.

I was driving on the highway in busy nyc doing 50mph in the middle lane and my car shut off. My dashboard did not display any warning signals (check engine, check oil, anything) prior to this incident at all. My safety and others were put at risk. This is a known issue with Hyundai vehicles. I researched their were prior recalls for engine issues however Elantras were not included in the recall. That needs to change. My car has an appointment for service however something needs to be done now about this issue. Things could’ve definitely went different. The maintenance on my vehicle is up to date. My vehicle is serviced at Hyundais service center. I’m extremely frustrated no warning lamps were ever displayed across my screen.

The contact owns a 2017 Hyundai Elantra. The contact stated upon coming to a complete stop, the vehicle accelerated unintendedly over a concrete bar and drove up a hill. The contact depressed the brake pedal but to no avail. The contact steered the vehicle to the right to avoid entering a pool. She then crashed into multiple objects including trees, concrete parking bars, and multiple vehicles before coming to stop. The air bags did not deploy upon impact. The contact was taken to the hospital by ambulance and was treated for injuries to her neck and back. A police report was filed. Due to the failure, the vehicle was towed to an independent tow yard where it was destroyed. Parking barriers and trees were damaged as a result of the failure. The manufacturer was notified of the failure. The failure mileage was approximately 25,000.

I can’t pinpoint the issue as it cannot be checked due to check engine light not staying on. I have narrowed it mostly down to being the ingnition coil packs as I have a cylinder 3 misfire listed. My car started having this issue in 2021. I would eat my lunch in my car and noticed a drop in rpm’s while idle along with vibration of the vehicle. It has progressed to vibrating while driving on the road and not being able to accelerate in a timely manner. I know 2 other people that have the same year of car and they are experiencing these same issues. You can find, on the internet, countless complaints related to the ignition coils failing in these vehicles. A recall needs to be created for the safety of the drivers and passengers in these vehicles. It is irresponsible for a company to use faulty components and proves that the safety of their consumers is not in their best interest. I will continue to report the issue until something is done about it.

When driving at night, sometimes the headlights and taillights will shut off leaving the car totally in the dark. This is a severe safety issue as you can no longer see the road and other cars cannot see you. The problem appears to possibly be associated with the light switch, as you can jiggle it and get the lights back on. Also related to this problem of the lights shutting off is the fact that occasionally the lights will come on long after the car has been parked in the garage, which tends to drain the battery. After experiencing this problem, I checked the internet and found numerous other cases of Hyundai Elantra owners reporting the exact same symptoms, so it seems to be a somewhat generic problem. Hyundai’s service department has been unable to isolate the problem on my car. The problem happens randomly and is infrequent but serious when it happens. It has happened approximately 10 times over the past two years.

Unknown. Battery died out on my twice, every two years. Motor needed to be replaced after 5 years.
