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 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.

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 realized that this is a common problem with Hyundai..

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?

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.

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.
