2017 HYUNDAI ELANTRA Engine Problems

After no previous issues, car stalled out multiple times on short drive to work. No warning lights and no subsequent diagnostic codes were reported. Upon final restart, engine started knocking severely. Upon investigation, the oil stick showed no oil in the pan. Vehicle was towed to trusted, licensed mechanic for evaluation where we were informed about the potential of a failure due to rapid oil consumption. The mechanic confirmed the engine failure to to oil loss. Vehicle had received regular, documented maintenance and fluids were checked periodically between cycles. There was no low-fluid indicator prior to the mechanical failure. Dealership-level conversations confirmed the rapid oil consumption issue for the 2017 Elantra is common, but because the vehicle VIN was not listed as part of a prior recall no assistance could be provided to repair the engine. The dealer provided a full cost quote of $9,000 to replace the engine block...

Driving on the highway in the far left lane. Check engine light came on, car stopped accelerating. Car came to a stop, car shut off. Smoke was coming out from under the hood and flames were seen underneath the car. Police and fire department arrived. Report states an electrical fire. Had car towed to Hyundai. Hyundai stated that the engine seized followed by the starter catching on fire. Car was only 2,000 miles in from last oil change. Was up to date on maintenance and safety inspection. Hyundai also stated there was a hole in the engine block. No prior issues with the car. The car would need roughly $16,000 in work done, confirmed by Hyundai. Car is now totaled. Car only had 121,000 miles on it.

With no 'low oil' warning, the car's engine started may a knocking noise. Then, all kinds of warning lights started. Parked the vehicle and checked the oil the next day and there was NO OIL in the engine. This should not have been the case considering this car gets regular oil changes. Also, there was no oil spots or stains on the driveway to also indicate an oil leak. This happened to my son while driving home from work on the interstate at 10:30 at night. That is concerning.

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...

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...

Component or System Involved Engine and internal lubrication system. The engine and related components are available for inspection upon request. Description of the Problem In January 2025, this vehicle experienced a catastrophic engine failure and seized. An independent repair facility inspected the engine and reported metal fragments in the engine oil, indicating internal engine damage. The vehicle was then transferred to a Hyundai-authorized dealership for major engine repairs, which were completed on January 18, 2025. Less than one year later, the vehicle developed excessive oil consumption. In October 2025, the engine stalled and was found to have no oil, despite having received an oil change approximately one month earlier. The vehicle is currently undergoing Phase 2 of Hyundai’s oil consumption testing. The dealership has indicated a full engine replacement will likely be required. Oil consumption has been measured at approximately 1.5 quarts per 1,000 miles. This vehicle is not currently...

Excessive oil consumption/ vehicle dies while driving.

The contact owns 2017 Hyundai Elantra. The contact stated while driving 20 MPH and depressing the accelerator pedal, the vehicle hesitated and stalled. The check engine warning light and the low coolant level warning light were illuminated. The contact stated that a bystander assisted in pushing the vehicle into a parking lot. The vehicle was towed to the dealer, where it was diagnosed and determined that the camshaft needed to be replaced. Additionally, the dealer diagnosed that the Continuously Variable Valve Timing (CVVT) and the timing chain needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 21V727000 (Engine); however, the model of the vehicle was not included in the recall. The dealer notified the manufacturer of the failure and was informed that the cost of the repair would not be covered because the VIN was not included in the recall. The...

I've owned a 2017 Hyundai Elantra for a few years now, and it has been a headache. Over the course of the past year and a half, the engine has went out (seized) not once, not twice, but three times without any warning. I go to start the car one day and the engine bay starts shaking and power of the engine goes either completely out or down significantly. It feels like a gamble every few months of if my car will simply stop working. I've had the engine rebuilt twice already and will probably have to have it rebuilt again for the same issue (the timing).

Check engine turn on , sent to shop for check up and they find out the engine is leaking.

The contact owns a 2017 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was able to be restarted. The contact also stated that the rear passenger’s side door failed to open when the unlock button was engaged. The vehicle was taken to the dealer, where it was diagnosed that the engine had failed and needed to be repaired. The vehicle was not diagnosed regarding the door failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 134,541.

Oil consumption, 1 quart a week with no known or visible leaks. 64,000 miles

When driving at low speeds(20mph and under) vehicle stalls. It appears to happen at random. It makes driving pretty dangerous for other vehicles that would not be able to tell the vehicle has stalled and hit me at low speeds. All electrics stay on, there is no check engine light. The problem first appeared after ignition lock was broken, even before replaced it started stalls at low speeds, seems to possibly happen more after engine is warmed up.

RAPID LOSS OF POWER FAILURE OF IGNITION COIL. HAPPENED FOR ALL FOUR. SUDDENLY UNABLE TO OPEN FRONT OR REAR DOORS ON PASSENGER SIDE. ACTUATOR FAILURES. BOTH OF THESE CONDITIONS REPORTED TO HYUNDAI, MY COMPLAINT IS THAT HYUNDAI IS WELL AWARE OF THESE PPROBLEMS DEALER CONFIRMED THEY ARE COMMON ACROSS MODELS. THEY ARE EXPENSIVE REPAIRS. WHY ARE THEY NOT RECALLS. COILS HAPPENED ABOUT 2023 WITH 55000 MILES (OUT OF WARRANTY). DOORS ARE CURRENT AND I CANT AFFORD $2000 FOR REPAIR.

While driving down the road, the car lost complete power. No warning lights came on until after the car had lost power. Car struggled to start back up. I put flashers on in hopes that others would notice my disabled vehicle in the middle of the road, while it was also pouring down the rain. The vehicle was towed to my local dealership where it was confirmed that I would need a new engine. The engine had a high oil consumption issue that caused it to stale while driving. The dealership informed me either there was a rod bearing issue or a piston slap in the engine. They recommended to park the car until fixed

I was told by the mechanic about the following. My car has shown engine oil burning issue, and it made the timing chain placing in the faulty function frequently. I changed the timing chain last year and was advised that I would need to check engine oil level because of engine oil burning issue. I was advised to check it at every 2500 miles. Recently my car showed check engine light on again, so I visited the repair shop and found out that the engine oil was totally gone before 2000 miles. The synthetic engine oil change should be at every 5000 miles. The rapid engine oil consumption made my car getting check engine sign on and I was told that it eventually would stop my car. And I was told that it is very hard to fix it because it is due to faulty engine issue.

The contact owns a 2017 Hyundai Elantra. The contact stated that after starting the vehicle, the vehicle lost automotive power and then lost power after driving a short distance. No warning light was illuminated. In addition, there was an abnormal sound coming from the engine. The vehicle was taken to a local independent mechanic; however, the failure was not replicated. The contact stated that the vehicle was previously taken to the same independent mechanic, and the spark plugs were replaced. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 150,000.

Timing chain looseness, Sudden loss of engine power/motive power. Vehicle was sold, unknown if available for inspection. Engine failure on and in the middle of the interstate/highway, and this caused a major crash risk, and safety hazard. This make and model of vehicle has multiple reports of similar incidents. The repairs would’ve cost over 3 times the value of the car. As stated by the vehicle manufacturer, the entire engine would need to be replaced, with a factory built engine in order to comply with NHTSA and safety regulations. I’m no longer in possession of the vehicle. It was sold. While the vehicle was operating, and drivable there would be a chime and a flashing check engine light/indicator on occasion. Although no codes were present at maintenance center, therefore unable to identify the exact cause.

Car had check engine come on with No significant symptom. Mechanic said this code leads them to either timing chain, phasers, or piston valve all located in the engine. The car does not have much time at this point. It’s very costly after just having changed all the oil gaskets from a leaky engine. Mechanic said it will suddenly get bad if left unpaired and could be dangerous for me while driving.

The contact owns a 2017 Hyundai Elantra. The contact stated that the check engine warning light was illuminated. The contact stated that the vehicle was intermittently shuddering while accelerating. The vehicle was taken to a certified mechanic who diagnosed that the timing belt and exhaust camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the dealer who confirmed the diagnostic results. The manufacturer was notified of the failure and opened a case. The failure mileage was approximately 108,000.

My car has been stalling and shaking for months on acceleration. This has put me in unsafe situations where vehicles are going very fast on the highway and I am going 20 miles under the speed limit, or I am accelerating to merge and my car fails to accelerate, or I'm on the regular road and my car slows to a crawl while people are coming in fast behind me. The Error Code is: Cylinder 3 misfire. Took it to the dealer, they said they couldn't find anything wrong with it because the light was not on, they updated the software, as soon as I drove home the problem came back. They still charged me $200 for service, even thought the vehicle is under powertrain warranty which covers the cylinder block head and all internal parts. Online research shows this is a common problem in 2017 Hyundai Elantras. Many tried...

November 1st, 2024 My husband and I were northbound on I71/75 at mile marker 160 while traveling in the high speed lane, doing 65 mph, when the car suddenly lost power, the check engine light immediately came on (NO prior) warnings. The car would not respond, had to coast to the side of road while traffic is whizzing past us at 65+ mph. The car at that point was DOA, lights would come on but motor would not respond . After many discussions with Hyundai corporate and sending them proof of eligibility for remaining factory warranty (window sticker information) that I was told in detail by the dealership representative. I was told emphatically that with it being a lease turn in that I was still eligible for all remaining warranties. Hyundai corporate says that even though I only have 88,000 ( odometer reading at purchase was 24,147) of a 10year/100,000...

Car has 86,000 miles Does not meet the 100000 threshold

The vehicle has been randomly shaking at idle since around 100,000 miles. There have now been a few instances where the engine will shake when decelerating. There are no warning lights, codes, or diagnostic readings that have given a solution for this. Around 145,000 miles the engine began to shake aggressively while driving, as I stopped and put the car in park the engine light, oil light, and battery light came on and then the entire system failed and the car shut off and could not be turned back on. This happened on a “highway” CA-108. I was stranded in the middle of the road, during school traffic hours. I towed the car to the dealership where they said they couldn’t replicate the concern but replaced the oil control valve. It has been 2 months since the repair, the vehicle is again starting to shake when decelerating. I now pull...

Issue with engine burning oil after I passed 104000 miles. I had my oil changed just after 100000 with no issues and just before the 104000 mile mark my Elantra began to make a clicking noise and my oil light came on. I took it to get the oil changed and I was told I was completely out of oil. I began monitoring the issue every few days and after traveling about 300 miles in a day I rechecked the oil level and noticed a definite drop in level. I contacted the dealer and was told nothing could be done due to the fact it was over 60000 miles and there were no active recalls. There is an TSB posted for the issue already. As well as there are recalls for the 2014-2016 hyandai Elantras burning oil after 100000 miles.

The contact owns a 2017 Hyundai Elantra. The contact stated that the vehicle was making abnormal sounds while driving. The vehicle was taken to the dealer, where unknown engine parts and a computer part were replaced; however, the failure recurred. The contact stated that while coming to a complete stop, the vehicle was jerking. The low oil pressure warning light was illuminated; however, the contact stated that an oil change had recently been performed on the vehicle. The vehicle was taken back to the dealer, where it was diagnosed with excessive oil consumption. The dealer determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the repair could not be covered because the VIN was not under recall. The failure mileage was approximately 202,000.

Motor locked up

My 2017 Elantra with 107,000 miles (it has a 100,000 mile powertrain warranty) on it has just experienced the same issue as all of the other Hyundais that have been recalled. I was driving on Xmas evening 2024 and started hearing my engine making noises I had not heard before when excellerating but then they would go away. On my way home the check engine light went on for a couple of minutes but then went off and I was able to get home although the car did not seem to be riding well. The next day, the check engine light went on again and so I brought it in to my mechanic. He said that there were metal fragments/shavings in my oil that were clogging my engine, etc. He said that I need a new engine and said he had several other Elantras with the same issue and that...

Ignition coil failure. Causing misfires and rough idle. Misfire initially found in cylinder 2 when check engine light illuminated and check with an OBD II reader. Swapped the cylinder 1 ignition coil with cylinder 2. Check engine light returned the next day with the same signs. Check engine light and rough idle. OND II code scanner now says misfire in cylinder 1. The rough idle makes for slow acceleration until above 20mph.

The oil level burns down to next to nothing approximately every 2 months, with no oil light warning or engine light. However, the engine light does periodically come on but shuts down itself before able to get it checked. The same issues occured with my son's 2017 hyundai which caused the engine to blow and catch fire. His was recalled and repaired. His was a different model. The oil burn on my car has occurred at least 3 times. The steering feels as though it is grinding at lower speeds an makes parking difficult as well. Both of these issues are most concerning.

The cars just stops running as you are driving. It's happened multiple times. We've changed the crankshaft sensor & cleaned the fuel system. We saw these remedies online as multiple people are having this same problem with their Hyundai.

Was driving my car noticed that it was running a little rough and took it in for an oil change thinking maybe it was being a little weird because of that. I religious have my oil changed routinely. The gentleman changing my oil told me there was oil in the engine. Went to Hyundai and they did a diagnostics and told me that something had come off in the engine and clocked the oil gallery not allowing oil to flow through engine and power train. Was told it would be a $9000 engine replacement. I only have 93000 thousand miles on it still owe 3000 on it. Hyundai knows that their engines have been having issues. Salesman at Hyundai was trying to force me to buy a new car because of this issue. he was only going to give me 2500 on my car but told me if it had...

Hyundai claims its engines have a 100,000-mile warranty, but my Elantra 2017 engine blew up/ broke down just after 890200. Therefore, I called the Hyundai corporate office to fix my car. I also approached local Hyundai dealers at Jaining Road Hartford, Connecticut, but they refused to resolve my problem and denied replacing my car engine. I have no choice but to fix my car. I filed my complaint to Hyundai case no. [XXX], but Hyundai is not ready to resolve this issue. I have spent $4000.00 from my pocket to put my car on the road. I am requesting for the reimbursement. I have all the repaired bills and invoices. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle has about 136,000 miles and was driving when the engine just started knocking. There were no engine warning lights or any other indications there might be an issue. We Towed the vehicle to the dealer, and they advised that it needs a new engine. We are the original owners and maintained the vehicle with regular service and oil changes.

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

All four engine coils blew before 60,000 miles. The car was being used and maintained properly and there were no associated engine or spark plug defects noted. However, all four original engine coils failed and had to be replaced.

2017 Hyundai Elantra SE sedan. Car starting stalling around turns and the next day engine had rattle and loud noises coming from engine. No lights to indicate problems prior to stalling out or engine issues.

The car engine is consuming too much oil causing the oil to run out of the car too soon. The car engine starts knocking & the car keeps cutting off.

Original catastrophic engine failure in Sept. of 2022 while exiting the highway, was able to safely leave roadway. Determined that the motor had suffered symptoms shared with models related to Recall 203. Hyundai honored "goodwill" repair, but the repaired motor began suffering substantial and sustained loss of power with evidence of cylinder scoring 1 year/20,000 miles after replacement. Secondary incident occurred while merging onto highway and required evasive maneuver to avoid collision. Car is now parked and cannot be driven due to inability to operate safely on the road. Summary of events, related correspondence to repair, goodwill repair sheet, and original purchase documentation attached.

Oil consumption. The engine eats oil and is now becoming a concern because timing is off. not to mention the numerous bills for other things going wrong now due to the oil consumption.

The engine failed without warning! The car stalled and could not be started again. There were no warning lights or indicators that the engine was having problems. The car had fresh oil and luckily I was just completing the safety check after an oil change. Had I been on the road, this could've been dangerous. The Hyundai dealership noted a seized engine with no further explanation without an extra $1000 charge. It will cost $10,000 to replace the engine that was well taken care of and only had 106, 748 miles on it.

Our Hyundai Elantra Se 2017, engine blown. Started with knocking sound and when we stopped on the side of the highway it powered down. We have been told that unfortunately so many of hyundai's vehicle engines have been super problematic within the last decade. We were stranded on vacation. Had to pay for towing twice and a rental car to get back to North Carolina because we had to get back to work. We also have had to pay to diagnose the vehicle twice. We had the issue diagnosed with an independent service center Tuffys Auto in St. Johns Florida and now it currently is at Hyundai in St. Augustine. We have been without our vehicle for over a month and with the trending problems with these engines we shouldnt have to come out of pocket to fix it. Hyundai corporate has not been helpful at all even though we...

The contact owns a 2017 Hyundai Elantra. The contact stated that the vehicle was experiencing an abnormal oil consumption and engine oil needed to be added on several occasions. The contact inspected the vehicle but there were no leaks were found. There was no warning light illuminated. The vehicle was taken to an independent mechanic where no leaks were found. The vehicle was taken to a local dealer, but the diagnostic result was unavailable. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

The vehicle engine is burning oil. I found my oil pan having little to no oil and having a burnt smell to it and only 70,000 miles on the odometer. Hyundai made me pay for to have a combustion cleaning to help with the issue and would not cover it! This could have had my car blow up having no oil

I've heard that 2017 Hyundai Engines have had some recalls and looking online at others with these vehicles also experiencing same problems. Car only has 82,000 miles and now cutting off in the middle of driving under 1500 RPMs also shaking until it cuts off. Seems these cars engine warranty should cover the attached repairs as we've always done excellent service on these vehicles. I'm trying to see if there is anything I can do as we now have a $3500 repair and have to get a rental car in order to get to work.

The engine of my vehicle malfunctioned. It is available for inspection upon request, it will have to be towed. The problem put myself and others in danger as the car stopped as I was driving in the middle of a 3-lane highway in the far left lane. Others were put in danger as they had to swerve to avoid hitting me. That itself could have caused a chain collision as other vehicles in the middle lane were put in danger. I was also at risk to get rear ended as one might not notice that my speed has stopped increasing. I have already had it towed to a local Hyundai dealership and auto shop; both said it needs a new engine. Towing receipt is shown below. I had no warning lights on my dash prior to the engine failure. A battery light and check engine light appeared after I was...

While driving on three occasions I was driving and my car completely shut off where I had to pull over once to restart the car. The other two times I was on the freeway and had to put the car in neutral and restart the car. I almost got hit both times on the freeway when this happened.

I'm having issues with my car and I don't feel safe riding in it. While driving it start to coast. If I make a turn it shuts down. I am having some of the same issues some elantra having but because the VIN# doesn't show a recall I'm penalize for having this car.
