general problems of the 2017 Hyundai Elantra - part 1

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).

The contact owned a 2017 Hyundai Elantra. The contact stated that they were informed by a family member that when the vehicle was turned on and moved into the driveway, smoke was coming from underneath the hood, where the engine was located. A while later, when returning to the vehicle, they noticed the vehicle had caught fire. The fire department was called and extinguished the fire. There were no injuries or medical attention needed. The contact was unsure if a report was filed. The vehicle was towed and determined totaled. The dealer was not contacted. The manufacturer was not informed of the failure. The failure mileage was approximately 160,000.

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.

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.

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.

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.

Engine light keeps coming on. . .

Car has 86,000 miles does not meet the 100000 threshold.

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.

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.

Motor locked up.

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 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 replacing coils and spark plugs only for the problem to return again a few months later. One successful fix found the computer needed to be replaced with a new one.

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 over when this happens though it typically stops within 45 seconds. I have seen the other Elantra engine recalls and feel as though mine fits the description.

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.

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 I should take it to a Hyundai dealer because of all of their recalls/class action lawsuits which extend warrantees, etc. For the same exact issue. I was able to drive the car there but it was not a safe drive. Their assessment was basically that I need most of my powertrain replaced to the tune of $4100. 00 but once they get in there, it might be more extensive and end up having to be replaced. However, they did not say anything about the metal fragments and when I brought it up to them, they acted like they didn't see them. However, my mechanic (with no skin in the game) said they were all over the place in my car's oil. So, I am a little wary that they decided to skate that issue, since it is the basis for all of their class actions, etc. I'm kind of stuck, Hyundai has my car and it really isn't drivable. I've checked many Elantra forums and have seen that this is happening to many other 2017 hyundi Elantra se even though they have not yet been added to the recalls/class actions, etc. I really think that the Hyundai engine issue is more widespread than just the cars on the current list and I hope that this is looked into as it is extremely dangerous and comes on very quickly without warning.

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.

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 warranty on the engine. Hyundai corporate says that because I wasn't the original purchased that the warranty is null and void. I feel like there is something very wrong here when these warranties can be voided at the whim of the manufacturer. I have since had to purchase another vehicle in order to make it to the va medical center for my husband and make it to the hospital for my cancer treatments.

The contact owns a 2017 Hyundai Elantra. The contact stated while driving at 60 mph, the vehicle stalled. The contact was able to veer to the side of the road. The check engine warning light was illuminated. The vehicle failed to restart and was towed to an independent mechanic, where the contact was informed that the engine pin that went into the crankshaft might have failed. The mechanic advised the contact that the engine would need to be taken apart for a definite diagnosis. The dealer was notified of the failure and informed the contact that the VIN was not included in a recall. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,000.

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 been in perfect condition then he would've 6000. This is not something I did to my engine it was something that came off in the engine and blocked the flow of oil.

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.

Driving 55 miles an hour on [xxx] engine shut off and seized I filed a complaint with Hyundai corporation claim number [xxx] they said they were going to make a decision October 25th still didn't hear anything called them back now they said October 30th the vehicle is sitting at webb Hyundai merrillville indiana. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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).

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.

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 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.

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.

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.

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.

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.

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.
