2016 Hyundai Elantra: engine failure

Filed Aug 29, 2026 · Engine, Fuel system · NJ

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.

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 federal safety agency 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.

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 the federal safety agency 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. 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 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 but also raises serious safety concerns. A sudden engine seizure while driving can lead to dangerous situations, potentially endangering both the driver and other road users. Given the severity of this issue and its implications, I urge the federal safety agency to investigate the possibility of a recall for engine-related issues affecting the 2016 Hyundai Elantra GT. It is crucial that affected owners receive the necessary support and that safety concerns are addressed promptly. Thank you for your immediate attention to this serious matter. I look forward to your prompt response.

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 buy a new engine. I declined since the multiple repairs paid for already were supposed to fix the problem, but they didn’t. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights for anything in over a year but I am still dealing with same loss of power and acceleration control issues.

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 warn me that there is an issue. My car has a low mileage 90700. It is weird to breakdown its engine especially I change the engine oil before the due date. Please help me and other owners to get a recall on the engine because as stated by the dealer it is a harmful problem and requires engine replacement. I appreciate any help you can provide to save my family and other families of Elantra owners.

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 cover it (mine was stated that failure was from the top). How is this not considered with the recalls of other Hyundai's that hold the same engine?

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 own rental and that they would reimburse only a portion of the rental. I seriously think that this is a recall issue.

Have 2016 Elantra with just over 65k miles on it, 2nd owner, performed an oil change every 3k-4k miles. Recently performed an oil change and in the oil was an astonishing amount of medal from the interior of the engine. Classic signs of premature engine failure. The car shakes while it’s in idle at a stop light. Performed a 2nd oil change a few days later, and again CHUNKS of medal debris in the oil.
