2016 Hyundai Elantra

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

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.

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)

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.

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.

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 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?

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.

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

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.

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.

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.

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 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.

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.

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.

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.
