Hyundai Elantra 2016 — Reported problems

I am reporting a recall remedy failure involving my 2016 Hyundai Elantra under Hyundai Recall 256 / NHTSA Recall 24V‑146 (trunk latch pawl defect). The McCarthy Olathe Hyundai dealership in Olathe, KS marked the recall as “completed,” but the trunk latch still does not open and the defect persists exactly as described in the recall notice. After the recall was marked complete, I returned to the dealership because the trunk still would not open. The dealership told me the issue was “trunk lid damage” from a prior accident and advised me to replace the trunk lid at my own expense. I paid for the trunk lid replacement, but the trunk still did not function. When I returned again, the dealership changed their explanation and said the problem was actually “rear frame damage,” and that they had been wrong to tell me to replace the trunk lid. Which I have audio recordings of but am unable to upload due to format restrictions. Despite these conflicting explanations, the recall defect remains unresolved, and I have been without trunk access for over a year. I contacted Hyundai Corporate (MyHyundai USA), but they responded that this was “not a part issue covered under warranty.” This appears to be a misunderstanding, because this is not a warranty claim — it is a recall remedy failure. The recall was marked complete even though the defect persists, and the dealership’s misdiagnosis led me to pay for repairs that did not address the recall defect. This situation has caused financial loss, safety concerns, and prolonged inability to access the trunk, spare tire, emergency equipment, and cargo space. I am requesting NHTSA to document this recall remedy failure and dealership misdiagnosis.

The motor started to make a ticking noise 5 months earlier. 5 months later at 180,000 miles a borascope finding, reveled all 4 cylinder walls were worn related to cylinder slap. Called Hyundai dealership and was told ithe car is too old and the milage too high for a warranty coverage.

Vehicle stalls while driving which is very dangerous. All dashboard lights go on prior to stalling. No engine light is on. Knocking sound coming from engine. Dealer states engine needs to be replaced. Car has been serviced regularly despite that Hyundai denies engine replacement. The knocking sound that engine does is common between this model and year but mysteriously there has not been engine recalls.

P0420 P0441 P0014 P1326 C1260 C1688 C2130 These are the codes that's affecting my car

Engine burned oil and had knocking sound, despite having regular oil changes. Stalked out while driving took to dealer initial said it was covered by the exerted coverage but ultimately denied. It had 111,000 miles on it. I believe this engine has the same issues as the others.

The oil light & check engine started flashing. Took it to the auto shop. The mechanic stated that the oil level is very low and the engine has a bad lower-end knock. Removed the oil filter and found metal debris in the oil. No oil leaks were found under the vehicle at all. Oil is being burned out through the exhaust. The vehicle needs an the ngine replacement.

Transmission P0731 code. Vehicle will not shift into 1st gear when idle but will stay in 3 or 4 gear. Speedometer would indicate high speed when pressing on accelerator. At traffic light when light turn green car rev but would not shift into gear. Has only 130K miles. Car was towed to dealer and required a new transmission.

2016 Hyundai Elantra (75k miles) experiences severe, un-commanded Loss of Propulsive Power and a Severe Drivetrain Instability Hazard. At steady highway speeds, the automatic transmission completely loses hydraulic pressure, slips out of gear, and unexpectedly drops into a temporary "neutral." The engine suddenly revs up to high RPM on its own while losing all forward acceleration. After coasting helplessly, it violently slams back into gear, causing the vehicle to lurch forward. This also happens from a complete stop.The vehicle's OBD-II system fails to illuminate the Check Engine Light or store fault codes during these flares, providing zero warning before a loss of propulsion.This dangerous transmission slipping has occurred intermittently for several years. I repeatedly took it to an authorized Hyundai dealership to address this crash hazard. Because there was no active Check Engine Light, the dealership dismissed my concerns, refused to document it, and sent me away without a diagnosis. Recently, the service department acted in bad faith by misrepresenting my warranty terms (falsely claiming it was only 7 years) and refusing a live-data diagnostic scan. The bad faith dealership was Murdock Hyundai of Murray in [XXX], specifically the service manager Tyler as well as Krateton. The car is a verified vehicle under the Hyundai Nu 1.8L Piston Slap Class Action Settlement (TXXK Campaign). An official safety escalation case is open with Hyundai Motor America under my corporate case number XXX. I request a federal safety investigation into premature transmission pressure failure in 2016 Elantras, as this vehicle is entirely unsafe to operate.

My driver side window has not been working for almost 3 years now. I have taken it to 4 mechanics and they fix it but only last a couple days. They have all say they can’t really do anything about it since they need an original piece. My AC is another issue I have that I have tried fixing 3 times now. The same issue happens they fix it and it last about a week or so. The longest it has lasted was 2 weeks. The mechanics each say it needs a new compressor and I’ve bought 3 new compressor already. I’m not sure what to do anymore.

The vehicle's security system malfunctioned immediately after service at Parks Hyundai of Gainesville on 05/27/26 for Recall 256 & Campaign P33. The alarm blares & emergency lights flash while I am driving on public roads. This defect first presented in the dealership parking lot upon pickup. This creates a severe safety risk: the high-decibel alarm is a major distraction, the flashing lights confuse other motorists, & the malfunction prevents me from using turn signals, violating safety protocols. I demonstrated this to the service manager on 06/10/26. While the technician acknowledged the defect during a road test & performed a 'cap reset' (documented on the repair order), this attempt failed to resolve the issue. Despite this, the service manager refuses to acknowledge the defect, claiming it is an 'intended feature' of a 2023 recall at a different facility (993). This contradicts the technician's findings & my years of incident-free driving until the work on 05/27/26. The dealership initially omitted my return visit from their records, only acknowledging it after I confronted them in writing. An independent shop confirmed this electrical failure likely stems from P33, but requires proprietary dealer tools to diagnose. Attached video proves the vehicle runs while the alarm blares, confirming no relation to old Campaign 993 logic. Attached Repair Order proves the technician acknowledged the defect & attempted a repair. Despite this, the service manager ignores the documentation, his own technician's findings, & my demonstrations, blaming my locking habits while refusing a deep diagnostic. After 16 days in their possession, neither the dealer nor manufacturer has provided a remedy. If this malfunction were an intended feature, it would be an ongoing hazard; it creates a distraction, causes a panic response, & prevents the adequate use of turn signals while in operation. The vehicle is unsafe, & the dealership & manufacturer have failed to provide a valid repair.

The car turns off while driving it without warning or anything. Place where I got it don’t want to fix it

Car randomly will not start or will start but have no RPM's. Last year showed a crank shaft sensor code and had it replaced but car is doing it again.

THE BACK DOOR ON THE DRIVER'S SIDE DOES NOT LATCH PROPERLY. THE DOOR WILL TRY TO CLOSE BUT YOU HAVE TO KEEP SLAMMING THE DOOR UNTIL IT WILL FINALLY LATCH. I ONCE DROVE A FEW FEET AND THE DOOR HAD TO BE HELD SHUT. IT FINALLY CLOSED. THE DEALERSHIP WAS CONTACTED LAST YEAR (2025) ONCE I READ ON REDDIT THAT A TSB/EXTENDED WARRANTY WAS ISSUED. BUT I WAS TOLD THAT IT DIDN'T COVER MY VEHICLE AND IF I BROUGHT IT IN, A DIAGNOSTIC FEE AND FEE TO FIX IT WOULD BE CHARGED. SO I DO NOT OPEN THAT DOOR ANYMORE, BUT THAT IS NOT SAFE. I''M AFRAID IT WILL OPEN AT SOME POINT WHILE I AM DRIVING.

Car just turns off randomly. This has happened at least 6 times within a month. Once on a highway. Last time it turned off a strange sound was coming out of the car also.

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

Issue: Hyundai recall denial for paint peeling defect My vehicle qualifies for the Hyundai paint-peeling recall, and the paint deterioration matches the defect described by Hyundai. Despite this, Hyundai has denied my recall repair twice. Approximately 2 1/2 years before the recall was issued, I applied a small touch-up to the affected area to slow the deterioration. This was done solely to protect the vehicle and occurred long before any recall existed. Hyundai is now using that minor touch-up as a reason to deny the recall repair, even though the underlying paint defect was already present. The paint continues to peel and worsen. Hyundai's refusal to honor the recall appears unreasonable and inconsistent with the purpose of a safety/defect recall, especially since the touch-up did not cause the defect and was done years before Hyundai acknowledged the issue. I am requesting that NHTSA review Hyundai's handling of this recall and their denial of legitimate claims.

My car turned off while it was in drive. The oil pressure light flashed on for a second then disappeared. The car did not have anything else seem like it is wrong. I was put in dangers way because it turned off right before I was about to turn onto a very busy street and if it had done that in the middle of the street I would have gotten into an accident.

The contact owns a 2016 Hyundai Elantra. The contact stated that while operating the vehicle, the air bag warning light remained illuminated. The vehicle was taken to the local mechanic, who informed the contact of a Manufacturer's Extended Warranty Coverage for the failure and referred the contact to the local dealer for assistance. The cause of the failure was not yet determined. The contact was informed that the vehicle was not covered under the extended warranty. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 53,600.

No accident has occurred as of yet (for my case). Ongoing issues with Hyundai left brake bulb and center brake bulb burning out due to over-amperage. These two are on their own 10A circuit separate from the 5A circuit for the right brakelight bulb. It appears that these two bulbs are possibly receiving 15A and therefore burning out prematurely (3 months or less). I recently replaced these two bulbs at the same time, and now my battery is shorted. To keep my battery charged, I need to pull my 15A Brake Lamp fuse while the car is parked. This has now caused my ABS light to come on, as that system relies on the signal from the 15A brake lamp circuit. I suspect that some 15A components (10A+5A) received 20A (15A+5A) and welded shut. I am still looking for it to trace it down, resources are limited and I'm intent on just buying the $35 diagnostics book. Hyundai dealership did not inform me that this fuse was pulled while I drove home from the shop yesterday, creating an unsafe condition. They quoted me $500 to replace a brake lamp relay and the ABS (I'm assuming the whole ABS, but maybe just the control module), I declined. My plan for now, as this car isn't driven much, is to trace it down and find the shorted component. From my research, this is clearly affecting many years of Hyundais and Kias, not just my Elantra and not just my year. In fact, it's SO common that there are facebook groups (such as this one [XXX] ) dedicated to helping owners remedy this defect. I think a recall service, and a full investigation of what is electrically wrong with these cars, and what the actual remedy should be, is necessary based on the amount of cars that could be impacted. Hyundai & Kia technicians I am SURE are intimately knowledgeable about this issue by now and us owners are on the hook, having only 80,000 miles of warranty on anything purchased used. Please reach out with any add'l questions. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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. The outcome depended on luck, timing, and location rather than any safety system functioning as intended. The engine was later diagnosed by an authorized Hyundai dealership as seized due to internal failure. Hyundai denied warranty coverage because a software safety campaign had not been completed prior to the failure, even though the failure occurred suddenly and without warning, leaving no opportunity to complete the campaign. However, at the time of the failure, the NHTSA recall lookup tool showed ZERO unrepaired recalls associated with this vehicle’s VIN. The campaign referenced by Hyundai is intended only to detect certain engine conditions and does not repair engine defects. In this case, the engine failed before any detection or warning could occur. The vehicle had just been refueled and was equipped with four brand-new tires, confirming it was being operated normally. This incident involved an unexpected and complete loss of engine power at freeway speed due to an apparent engine defect, presenting a SERIOUS SAFETY RISK to the driver and other motorists.

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.

On [XXX] I was struck by a OVI driver at 50mph the side airbags deployed however the front airbag never deployed. The vehicle was totaled out my insurance company. The vehicle had no record or open recalls for the airbag and had been given a multiple point inspection in November 2024 with no issues noted.

The contact owns a 2016 Hyundai Elantra. The contact stated that while her daughter attempted to adjust the front driver's side seat while the vehicle was turned off, the front Driver-side air bag had independently deployed. No warning light illuminated. In addition, the contact's daughter's left arm was injured on impact with the air bag. Medical attention was sought, and further medical diagnosis will be scheduled. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 160,000.

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.

Vehicle started to violently lurch when shifted into drive. A week later loud clunking sound also started when shifting into drive. Sometimes would not go into drive and had to use manual 1st, 2nd, etc. Reverse was fine, no issues. No dash lights ever came on. Auto parts store had error code P0722. Have a diagnostic appt in a week at local Hyundai dealer. We may attempt to replace input/output speed sensor to solve, but probably will let dealership do diag first. Mileage approx 84686. Very dangerous at stop lights if can not get car into drive. Crash risk is high.

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.

The trunk latch was recalled. I supposedly got it fixed in July 2024. It was functioning at the time it was supposedly fixed. It Does say it’s a safety issue.Now it is not working, exactly the symptoms of the recall, not open from the inside. There isn’t a key hole to open it. My belongings are inside, and if I get a flat, there is no way of opening the trunk. I’ve called their corporate office. They want to charge me a diagnostic fee, of $200.00 to check the recall. Isn’t it their legal obligation to check if the recall has taken affect?

My fuel pump comes up and my check engine light saying that it needs to be replaced when I fill up my car it automatically resets my mileage for AAA and trippy and it will tell me that I have no gas even though I just filled up or it will say I’m full when I know I’m empty so it’s not reliable. It comes and goes. And then for an electrical issue my Car will randomly stop working and then like come back up and it was underneath the positive plug. there is a clip that someone had to extend because it was too short and causing electrical surges so it’s still a problem if I go over a bump it gets loose so that clip under the positive terminal I believe is loose and makes my car shut off in the middle of driving at once and then it came right back on

No incident as of yet, however there are multiple Hyundai vehicle owners whose air and lights have come on after having the vehicle for at least 5 years. Other manufacturers have issued recall notices on this matter, but not Hyundai.

Paint delamination has exposed bare metal on hood/roof/trunk. Corrosion is spreading, which can compromise crashworthiness and latch integrity. Additional peeling near the window trim near the roof is beginning to corrode. This part of the vehicle is structural and could compromise roof strength. This issue is a world wide(yes Canada too) has understood this issue and has consistently been on the news.

The contact owns a 2016 Hyundai Elantra equipped with Waterfall Tires, Tire Line: Eco Dynamic, Tire Size:195/65/R15, DOT Number: 48AEYUEN. The contact stated that while performing an oil change on the vehicle, the contact discovered that the steel belt was exposed on the front driver’s and front passenger’s side tires due to severe tread separation. The dealer that sold the contact the tires was notified of the failure and informed the contact that the tires had exceeded the 90-day warranty period. The contact was then informed that the tires were still covered under warranty through the manufacturer. The contact made several attempts to reach the tire manufacturer through email but had not received a response. The tires were replaced. The tire failure mileage was approximately 12,000. The vehicle failure mileage was approximately 134,000.

The contact owns a 2016 Hyundai Elantra. The contact stated that while driving at 45 MPH, the vehicle jerked with an abnormal sound coming from the transmission while shifting gears. In addition, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle stalled. No warning lights were illuminated. The contact was able to coast to the side of the road. The vehicle was towed to the dealer, where it was diagnosed with transmission failure due to a workmanship error. The contact was informed that the transmission needed to be replaced. The vehicle remained at the dealer unrepaired due to the cost. The dealer notified the manufacturer of the failure and submitted a request for a new transmission. The manufacturer declined the request. The contact notified the manufacturer and was informed that there was no Extended Warranty on the vehicle declined to offer any assistance. The failure mileage was approximately 93,000.

My trunk latch hasn’t worked since January. I took it in to McCarthy Olathe Hyundai in Olathe, KS on January 13th for an appointment but they didn’t have the parts available so we rescheduled. When the parts were in, my fiancé took it back on February 18th, 2025 but was told that the repair couldn’t be done since there was previous trunk damage. I explained via the telephone that the damage to my truck was minor from an incident two years prior and that it hasn’t caused any issues with opening or shutting the trunk since. But the gentleman I talked to reiterated that the recall repair to my trunk latch couldn’t be done. I recently found out that the recall was marked as completed when it was not. I don’t know what to do!

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. Here we are only 19,000 miles later and the same issue is occurring; except this time due to the stress the failing engine is putting on the torque converter the transmission is now failing to do its job properly. I have been back to the dealership but they offered no help except lies (they told me my high pressure fuel pump was bad, this model doesn't even have one!!!!!) I fully intend to sue Hyundai of America unless some appeasement can be made. Do not EVER buy a hyundai, they are trash cars made to look nicer than they are. Additional details will reflect most recent incident with engine/transmission.

I was driving normally down the road and all of a sudden I lost control and couldn’t turn my vehicle apparently the control arm rusted from the subframe, causing me to swerve hit a curb and cause more damage to the front end. Thank God I was on a not so busy street! I could have killed myself or someone else all because this company’s metal rusted out.

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 happens while driving the car.
