general problems of the 2017 Hyundai Elantra - part 1

I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving. This most often occurs when I am decelerating and turning, such as when entering or navigating roundabouts. At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the failure occurs—no unusual noises, no loss of power leading up to the event, and no dashboard warnings in advance. The stall is sudden and unexpected. When the vehicle stalls, I must quickly shift into park and restart the engine. The car restarts immediately without hesitation, and all warning lights disappear. The vehicle then operates normally again until the issue randomly reoccurs. This has happened multiple times. This issue creates a safety risk because the vehicle loses power unexpectedly while in motion, particularly during low-speed turns and in roundabouts, which could increase the risk of a collision due to sudden loss of propulsion and reduced control. The problem has not yet been formally diagnosed by a dealer or independent repair shop, but based on research and similar reported cases, it may be related to an intermittent engine or electrical signal failure. The issue has not yet been inspected by the manufacturer, police, or insurance representatives. Unknown as to the exact failed component, but the failure appears to involve a sudden loss of engine operation without warning, followed by immediate recovery upon restart.

There was a recall electronic power steering (eps) motor connector that was being done for 2017 Hyundai Elantras and my car is affected by it. Hyundai is saying my car is not affected by the recall that they put out for this issue.

1: driver’s window: don't go up or down, it doesn't respond to control. 2: headlight warning lights is on all the time because bulbs are burn out so soon after replacement .

While driving, pressing the accelerator pedal, the vehicle hesitated and stalled. No warning lights came on until after I attempted to turn the vehicle back on then the check engine light and low oil light were illuminated. My vehicle was towed to a local mechanic and I was informed that the engine was blown and to tow my car to a Hyundai dealership as I was still under the 10 year/100k mile warranty. After getting my car to Hyundai, I was told I had to get a combustion cleaning for $800 whether the cleaning worked or not before any warranty work could be completed. The cleaning did not work and it was then found that a pin was sheared off inside the engine. My engine was then replaced under warranty but I still had to pay for the cleaning. A second mechanic looked over my paperwork after getting my car back 2 months later and noted that the engine failure could have been diagnosed without the cleaning as the cleaning would not have affected where the pin was sheared off. My 2017 Elantra had 90,315 at the time of this incident.

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. .

Component or system failed: the electrical and/or engine system failed spontaneously. Gray smoke originated from under the hood, followed by black smoke and an intense fire. The vehicle is not available for inspection as it was declared a total loss and scrapped 30 days after the incident. Safety risk: my safety was at immediate risk as I was inside the vehicle when the fire began. Public safety was also threatened; the bloomingdale fire department had to evacuate a wendy’s restaurant and its customers for two hours due to the intensity of the fire and smoke. Confirmation of problem: the problem was confirmed as a total loss due to fire by the bloomingdale fire and police departments on the scene. Inspections: the vehicle was inspected at the scene by police and fire officials. No manufacturer or dealer inspection was possible because the fire occurred only 7 days after purchase and the vehicle was destroyed. Warning symptoms: there were no warning lamps, messages, or symptoms prior to the failure. The smoke appeared suddenly while the vehicle was parked and idling.

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.

I am filing a formal complaint regarding my 2017 Hyundai Elantra se (VIN: [xxx] ). The vehicle is currently experiencing severe safety issues, including unexpected engine stalling and loud mechanical rattling, alongside a p0014 diagnostic code. These symptoms align directly with the defects described in recall 203 (NHTSA 21v301000) involving improper piston ring heat treatment and service campaign 966regarding engine bearing wear. As a consumer, I am extremely concerned about the risk of a crash due to sudden loss of power. I am really concerned for my son and I as I drive my vehicle. I am requesting: 1. An immediate inspection and confirmation of eligibility for an engine replacement at no cost to me. 2. Verification of the lifetime long-block warranty extension associated with the ksds (campaign 966) update. 3. Provision of a loaner vehicle or rental reimbursement while my primary vehicle is unsafe to operate. Please assign a case manager to this matter and provide a timeline for resolution.

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.

To whoever it is that can help, I am reaching out to submit a formal complaint regarding my 2017 Hyundai Elantra due to ongoing mechanical and structural issues that began very shortly after I purchased the vehicle, which have progressively worsened. I made the purchase in January 2024 for approximately $13,000 with 60,000 miles. The vehicle now currently has approximately 108,000 miles. Since purchasing the car, I have experienced consistent time consuming and serious issues that I believe indicate defects in manufacturing or design. First, the thermostat had failed during the first winter season I owned the Elantra, despite replacement the vehicle’s heating system still does not function properly. I’m not a fan of the cold. Also, the engine burns oil at an extreme rate. I am required to add oil literally every 2–3 days to prevent the engine from running dry, which presents a serious risk of engine failure and potential safety hazards while driving. And is also costly as oil is not cheap. In addition, the vehicle’s headlights developed spiderweb pattern cracking and shattered from the inside after approximately nine months of use, without any external damage. The paint has chipped across the vehicle, including in door jambs and other protected areas, suggesting poor paint quality. And recently, the lower engine underbody cover has completely broken down and disintegrated over time due to clips constantly falling out. Given the age of the vehicle and the normal use, the amount and severity of these issues are unacceptable. These defects have caused significant financial burden and raise serious concerns on vehicle safety and manufacturing quality. I am requesting that this complaint be reviewed for potential defects or recalls. I would also like Hyundai to be held accountable, either through compensation for the repairs required or replacement. Thank you for your time and attention to this matter. Sincerely, owner of the 2017 Hyundai Elantra.

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).
