2016 HYUNDAI ELANTRA Engine Problems

So I have a suspicion oh a connecting rod, might be a bearing but it’s making a tik tik noise, no other issue than that, no engine light no nothing, been doing it for a while but car still goes great

I received confirmation from my local Hyundai dealership that my 2016 Hyundai Elantra GT is consuming over 1.8 quarts of oil every 1000 miles. The mileage is currently 70k miles. This is not the result of lack of maintenance or neglect but because of Hyundais engine design. I was told by the local dealership that I would need a total engine re build. This was the only option to fix the issue 100%. I was told that if the issue is not fixed it will result in engine failure. Hyundai is not recalling their engines or acknowledging the inherent danger this will cause. I am at my engines will if I cannot afford this repair because Hyundai won’t honor the Powertrain warranty.

While driving on the freeway at normal highway speed, the vehicle experienced a sudden and catastrophic engine failure. The engine immediately lost power, and the vehicle shut down within seconds. There was no prior warning or opportunity to take corrective action. The vehicle became completely disabled and could not be driven. This occurred late at night with limited traffic, and I was LUCKY to be near a freeway exit. I was able to coast toward the exit, but the engine seized fully, resulting in total loss of propulsion and blocking the freeway exit ramp. Law enforcement had to assist due to the disabled vehicle creating a traffic obstruction and safety hazard. A tow truck was required to remove the vehicle because it could not be restarted or moved. Under normal traffic conditions, this sudden loss of engine power at freeway speed could have resulted in a SERIOUS, potentially FATAL COLLISION....

Engine turns off unexpectedly when driving. all power steering and brakes stop working when engine itself off. entire engine, drive train, and vehicle shakes while driving. Transmission is a replacement as first one failed after 90 days of purchase. paid labor for replacement and waited over 6 weeks without a vehicle. Now replaced oem transmission slips out of gear. making vehicle difficult to drive as the transmission and engine sputter and make ride jerky. car has turned off on the freeway in traffic 3 times. almost causing an accident each time. car has been robbed at least 5 separate times. stealing items within the vehicle. car was locked and next day it is unlocked and my stuff all gone. i am scared to drive the vehicle. i believe it is a lemon.

The coolant system is failing after it was fully replaced in November of 2024 and i got The car of may 2025 with only two previous owners. Coolant system failing after me only have the car for 6 months when the car sat for 5 months.

I own a 2016 Hyundai Elantra, and the engine makes a noticeable knocking or “tapping” noise when started cold. The sound resembles piston slap and usually lessens as the engine warms up, but it’s been gradually getting louder over time. It’s most noticeable for the first few minutes after startup, especially in cooler weather. I’m concerned this may indicate premature piston or cylinder wear. I’ve found many other 2016 Elantra owners reporting the same problem online, suggesting it may be a design or manufacturing issue. The vehicle has been properly maintained with the correct oil grade and regular service, so this shouldn’t be happening at this mileage. This could eventually lead to engine failure or costly repairs if the piston or cylinder surfaces deteriorate further. I’m reporting this so NHTSA can track the issue and determine if it poses a broader reliability or safety concern.

Bought a 2016 Elantra in 2020 with 44,000 miles on it and a clean repair/ maintenance history. Let me preface the rest of this by saying I am an ASE certified mechanic of 15 years who has been in the industry even longer. The first major issues I incurred with the vehicle happened approximately one year after purchase. The lifters started tapping and not long afterwards (about a week) I had a total engine failure on my hands. I was almost killed by a passing semi truck that was merging on to the interstate but was luckily able to avoid it and get the car on the side of the interstate where I had it towed to Ralph Sellers Hyundai in Baton Rouge Louisiana. Long story short , even though the second owner is entitled to a 5 year, 60,000 mile warranty, they made me pay for a new engine....

While driving the car will stall regardless of speed or distance. Hyundai dealership states that this is due to a drop in oil pressure due to a faulty oil pump. I replaced this pump 18 months ago on 6/7/2023 with 87K miles. The car is displaying the same issue again on this date (1/14/2025) with 104K miles, and I took it to the Hyundai dealership, and they state that it is experiencing the same oil pump failure. The service department at the dealership stated that this is a known issue with these Hyundai Elantras, and this would be the third replacement of this oil pump. It was replaced once by the original owner under warranty. My contention is that this is a safety issue, because when the oil pressure dips the engine shuts off, and we lose all power to the car. This is a danger to us if this...

engine noise knocking sound, car hesitates and vibrates, reduced power...all getting worse...I try to avoid driving the car as much as possible.

I am writing to formally request an urgent investigation into a potential recall for my vehicle, a 2016 Hyundai Elantra GT. I purchased this vehicle in 2017 and completed my payments in March 2023. However, in late July, I experienced a catastrophic failure that has rendered my vehicle inoperable. While driving home from work, I suddenly experienced a complete loss of power. My car slowed down significantly, forcing me to pull over to the side of the road. Once I came to a stop, the engine failed to restart, despite the dashboard lights and radio functioning normally. It has now been over two months since my vehicle has been non-operational. After taking it to a certified repair shop for diagnosis, I was informed that the engine is seized. The estimated cost for repairs exceeds $13,000, which is financially unfeasible for me. This situation not only poses a significant financial burden...

I hear a lot of sounds from the engine of my 2016 Elantra that’s only 96600 miles. It sometimes pulls back even though I step on the gas, and when the car is not moving it shakes a lot, though there is no problem according to my mechanic.

This car is consuming oil to the degree that it is empty 1,000 miles after an oil change. The engine has stalled out on the highway twice, and once on a back road. It will not accelerate properly, and won’t go over 40 mph. I had the catalytic converter replaced less than a year ago, and I am experiencing these issues all over again.

The contact owns a 2016 Hyundai Elantra. The contact stated while driving at an undisclosed speed, the RPM fell to ZERO(0) and the vehicle hesitated while accelerating. The check engine warning light was illuminated. The contact was able to drive to the destination. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

I was driving down the interstate when my car completely locked up, my brakes stopped working, the steering wheel wouldn't turn, the car completely shut down, so I had to make my way off the bisy interstate luckily I didn't have an accident so I took it to a mechanic and found out the alternator went out, so it was replaced then less than a year later i had issues with the headlights not working then magically comong on while driving, and the interior lighta will work then bot work but the bulbs are new, leading to another replacement alternator, then less than about 8 months pass and I have issues with the electrical stuff again not wanting to work even when new bulbs are pit in the car, the radio turning on and off by itself and I've had to put it a third alternator in less than 3...

I just know that my vehicle has a high use of engine oil. I took it to the dealer about a year and half ago to have it checked but they said that was normal but the more I read up on this it sounds like it is not normal. Also the clear over spray paint on all 4 door handles has come off and the rear hatch top window spoiler has completely peeled off also.

Bought the car a yr ago and transmission started slipping and stalling sometimes even engine shutting off while driving at higher speeds unable to steer and when pulling into traffic is on interstate almost got hit because I could not speed up it's also using double the fuel while driving longer distances I tried to use my warranty 2x before my warranty was up but both neither time did Hyundai in Owensboro check what I booked the appt for. First one was booked to check transmission and power issue then called the day before and added oil change. When I arrived the tech retyped my order and changed the oil. Brought my keys I asked about the power/transmission issues and was told they didn't know to check that but at that point there was no time and had to reschedule... So I did. Waited almost 2 months booked appt for...

Initial report on March 7, 2022 (approx. 94K miles), second report on Dec. 12, 2023 (approx. 111,700 miles). Third report March 27, 2024: Recent event occurred on March 23, 2024 (approx. 112K miles) when my vehicle suddenly stopped moving while driving 55mph on a freeway with child passenger in the vehicle, putting both of us at risk for collision. Vehicle did not have any warning lights turn on prior to or during event. The vehicle did not move again after multiple attempts to accelerate to exit freeway safely. After shifting to neutral and back to drive, the vehicle suddenly jolted and accelerated randomly while holding foot on the gas pedal (no control over timing of acceleration). We were able to exit the freeway safely. This same issue repeated multiple times while driving us to a safe area to call for a tow truck. The vehicle was towed to dealership location...

What component or system failed or malfunctioned, and is it available for inspection upon request? Available for inspection upon request. Please do! Loss of power. Reported same issues a year ago. Brought to dealership, sold on other services that did not solve problem. Opened a case with Hyundai. No solution. How was your safety or the safety of others put at risk? Random loss of power. Hyundai rep stated it’s a problem their systems do not actually scan for so it’s common this won’t appear in inspection reports. Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer rep drove my car and mentioned he noticed it tries to accelerate when idle, but without a code he can’t do anything about it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A Hyundai dealership inspection was completed. Suggestion I...

There are times when I turn the key and everythings turns on, lights, radio, air/heat, dash lights but the engine does not. I have been stranded multiple times and later the car will start. Replaced starter and it was not the issue. Battery tested fine.

The contact owns a 2016 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the emission valve sensor needed to be replaced. The contact's son diagnosed the vehicle and retrieved the DTC code: P0017 (Crankshaft Position). The vehicle was then taken to an independent mechanic, who replaced the emission valve sensor, variable valve timing (VVT), VVT intake, camshaft position sensor, timing chain, and camshaft sprockets; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to take the vehicle to the dealer for assistance. The failure mileage was approximately 44,000.

Component or System that Failed or Malfunctioned: Engine or other I was driving my 2016 Hyundai Elantra in Kissimmee, FL, 34746 when the engine suddenly lost power and the car stalled out. The rpms dropped to 0, and the car could not be restarted. I was able to coast to the side of the road, but I was nearly hit by oncoming traffic. After several minutes on the side of the road, I was able to restart the vehicle to arrive safely home. The vehicle also shuts off at stop lights, drive-through, or idle. How was your safety or the safety of others put at risk? The loss of power while driving could have caused a serious accident. If I had been in the middle of the road or if there had been more traffic, I could have been hit by another vehicle. Has the problem been reproduced or confirmed...

AFTER MY OIL CHANGE 2500 MILE LATER THE DRAIN PLUG FELL OUT FOR NO REASON

So we went to Take Five in Kenosha for an oil change on the way home the oil filter snapped off completely.

I bought the car used from a dealer a year ago. I've made sure to keep the oil changed and have regular maintenance. I was driving home after work, and in the middle of highway 49, going 65mph in the left lane, the car stalled and came to an abrupt, jolting stop in the middle of traffic, causing several other cars to nearly hit me before I was able to get a man who was passing by to help me get the car off the road to safety until I could have it towed to a mechanic. It wouldn't crank or start. After he replaced my starter, it cranked and seemed fine. I headed home but halfway home it began knocking on the passenger side of the engine, getting worse with acceleration. The oil is at the proper level, so it's not from lack of oil. After reading online, I...

I do know it’s the catalytic converter it causes the car to stall while driving and it’s going to cost 1500 just for the part that’s not including the labor

Car was turning off while I was driving it. I would be driving and the car would literally just stop... this is very dangerous at high speeds. Just got a call from the dealership and they said it is the engine and is $7,000 to repair. The car only has $120,000 miles on it and it has been maintained well!

My 2016 Hyundai Elantra had an oil change and mechanical check up on April 14, 2023. Everything was considered to be working correctly. 2 days ago, upon turning the car on to return home, the motor completely dies without warning. This car was purchased 5 years ago and has been properly maintained. In addition, while there hasnt been an official recall with Hyundai, many people like myself have experienced this same issue in one way or another.

While driving on 4/24/23, engine suddenly died and it was revealed to be a blown motor, even though the car was inspected during an oil change and nothing was found to be an issue. Lack of notification or accountability regarding this issue is infuriating.

My Elantra stalled while driving twice the other day. The first time I occurred on a Highway inter belt and the second occurred in slow moving traffic. I had the car evaluated by 2 different repair shops. Both said they could not reduplicate the problem or find any malfunctioning codes. No warning lights appeared when the car stalled. I had this happen before last fall. I had it repaired. They changed spark plugs, performed engine oil system purge, serviced fuel injector and air induction and realigned tires. Until the day before yesterday, the car performed well. In researching my car issue, I have learned that this is a top complaint of many 2016 Elantra owners.

I purchased my car 10 months ago. It has rebuilt title without any structural damage. The accident was in the body only and no one touched the engine. It was in perfect condition and it was driven without any problems for the last 10 months. Two weeks ago, I noticed a ticking noise come from the engine whenever the car accelerates. The noise wasn’t exist before, it just happen. I took the car to firestone and they stated that it is common problem in the engine appears in this model. I took it to the dealer (Hyundai of Cookeville) and they state that engine require replacement and it is a harmful issue. I looked over the internet and I found that it is common problem between owners of Hyundai Elantra especially 2012 to 2016. It is worth noting to mention that there is no any warning lamp turned on to...

No mechanical issues . Left work one morning driving to work . Made it home turned the car off .and the car never cranked back up . Sent to shop for assessment says the motor . I have routine maintenance done . No check engine light appeared . Car had been jerking on and off

my transmission failed while driving, car stopped being able to accelerate, i was luckily in my neighborhood but if this happened on a major road I could’ve been seriously injured or even killed. i had to tow it to a local shop and they said they have to completely replace the transmission. no prior warnings on the dashboard or any indications my car was about to fail. I only had slight issues a week beforehand. this vehicle is unsafe and costs thousands to repair

Car stutters at low speed.

Leaving work on 1/24/23 my car failed on the 4 lane, on the ramp coming into the town I live in, and again in the middle of a 4 way intersection. I only live 2 miles from where I work. My engine light was flashing, lost all power/acceleration, transmission would not switch and kept my RPM's really high, took multiple times to get it re-started, and engine was knocking/surging/sputtering. I got it taken to my local shop the next day and they told me my engine needs to be replaced. It was throwing 6 different timing codes and my oil was very shiney (filled with metal shavings). My car was not leaking oil, all services were kept up to date, any mechanical issues were always taken care of, and my car only had 92k miles on it. If the engine failure wasn't from the bottom of the engine, warranty won't...

Driving then while stopped at a red light out of no where the engine starts shaking like crazy, once it turned green and I took off the engine light came on then immediately turned off after accelerating. Add oil Was working perfectly fine until a week later it did the same thing the. Engine light came on but seemed faulty as it would blink, shut off then be solid, and then fluctuating like crazy then all that stopped after the car was turned off. Later that day I drove it and it wasn’t accelerating properly. Next day when getting it looked at the second we started it white smoke everywhere

The engine stalled after fluctuating power from the throttle and accelerator. The engine began making a knocking sound as I tried to bring the vehicle off to the side of the road with a loss of engine power. No warning lights or indicators displayed on the dashboard the indicated the engine was malfunctioning. This malfunction or engine defect caused a serious decrease in speed which impeded the flow of traffic leading to to the chances of being in an accident or having the engine explode without warning. This vehicles malfunction jeopardized my safety, my passengers, and the other drivers on the road.

Car suddenly started to jolts while decelerating from 25mphs -20mins. Car “stall & jolts” from park to drive. Stuck in park for a couple seconds. Dangerous , unable to go from park to drive is a safe timely manner No check engine light or trouble codes, car is maintained

The contact owns a 2016 Hyundai Elantra. The contact stated that while her son was driving at an unknown speed, the vehicle stalled with the check engine warning light illuminated. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that there was a hole in the engine block. The contact was informed that the engine needed to be replaced. The vehicle was then towed to the dealer where it was diagnosed that the starter needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was provided a case number. The manufacturer offered to cover a percent of the cost of the repair. The failure mileage was approximately 125,000.

Fuel Injector went bad in engine with 77k miles & they won’t honor the repair. The car had a knock sensor recall that I never received a letter on & received no warning that the engine was failing.

idle was rough when car was at the stop light, etc. Took car in to the dealership and they confirmed the issue. Car engine replacement has been approved by Hyundai Motors. I think that the NTSB should be looking in to this as there are currently 71 cars ahead of mine, with the same issue, at this one dealership. Other Hyundai dealership must be having the same issue, this cannot be happening only at this dealership. My engine will not be replaced until April, 2023. It is now October, 2022. That is the reason why the dealership has no cars to loan, the wait list for their car loaners is four months. I am the only owner of this car. I purchased it brand new from this dealership, and have followed the advised maintenance for this car. The "Customer Care" (big joke) told me that I have to pay for...

My engine has almost completely burned through its oil twice. I have done routine oil changes and maintenance on the vehicle and the first time this happened, I had driven 3,000 miles since my last oil change (full synthetic, so it should be able to go up to 5,000 miles). The second time, it was out of oil at 1,200 miles. I took the car to Hyundai after the first incident and they said no error codes came up, so there was nothing they could do. This safety issue could cause my engine to stall mid drive, causing a potentially fatal accident. There are no warnings that the engine is low on oil, making this an even more alarming and dangerous defect. Hyundai will not help consumers with this issue, and there is a class action lawsuit against them right now for this problem. Many are saying the exact same...

88,750 miles - Engine began profuse knocking suddenly when traveling down the road under 50mph. Stopped at a service center and they found no oil in the engine. Like THOUSANDS of others with the same complaint, the engine burned the oil which caused it to destroy itself LONG before the oil change interim had arrived.

I believe it is the transmission/ power train that failed. It slides gears and the engine stalls. While driving, I was almost hit because I could not speed up. I had to decelerate in order for the gear to not stutter.

At 75,000 miles my engine randomly blew on the freeway, I rolled down the off-ramp where I lost all power and had to put it in neutral and put the emergency brake on so I didn’t roll through a red light at the bottom of the ramp. Absolutely no warning, nothing else was wrong with the car, mechanic said oil and everything else looked perfect but that it was a manufacturer defect due to the pistons in the engine. Now I owe 8.5k on a car I can’t drive because neither insurance nor Hyundai will take responsibility. Great 👍🏻

Going through oil like crazy, continuous engine knocking

On 06/10/2022 Going down the road went to shift gears and it was stuck in 5th gear. Finally got it released and safely made it home. Ever since you can shift the gears and reverse while engine isn’t running but once I turn on the vehicle it refuses to shift into any gears including reverse. I have a FIXD OBD2 sensor and it showed no warning messages before, during, and now. No codes are showing up when plugged in. Matter of fact it says there’s no issues with my car ? I had a mechanic take a look since he was willing to come to my house considering I currently don’t have the funds to get it checked out & he said it’s probably my clutch has went out, but that can’t be the case considering it will turn on still. I have no messages appear on the dash &...
