2019 Hyundai Elantra: engine knocking or ticking

Filed Sep 26, 2026 · Engine · MS

I am reporting that there is not a recall but a factor warranty from the manufacture. Stating that the o ring in the 2019 hyundai elantra was not properly tempered. Which will cause the car to stall, rod bearing to break, and cause the car to set on fire. My report is that my 2019 hyundai elantra with 139,000 miles has did exactly that. O ring was bad and the rod bearing broke. When calling hyundai to report it they claim that my vehicle Vin number doesn't fall under that manufacture recall. Why doesn't it? This is exactly what happen to my car!!! Can anyone please help me. Thanks

The contact owns a 2019 Hyundai Elantra. The contact stated that while her husband was driving 35-40 MPH on a bridge, the engine made a loud banging and knocking sound, and the vehicle stalled. The driver shifted into neutral, coasted down the bridge with the engine off, and pulled over to the side of the road. The driver noticed an abnormal burning odor coming from the vehicle. The vehicle was towed to the residence, where the contact's husband performed an oil change and discovered a hole in the side of the engine block. The vehicle was then towed to a dealer, where it was confirmed that the failure was associated with the federal safety agency Campaign Number: 21V301000 (Engine); however, the repair was not covered because the VIN was not included in the recall. The failure mileage was approximately 120,286. The VIN was unavailable.

2019 Hyundai Elantra with 2.0L Nu MPI engine suffered catastrophic engine failure at approximately 118,530 miles. Vehicle is currently at the [XXX] Hyundai dealership. Vehicle appears to fall within the exact parameters of Hyundai Recall 203/the federal safety agency 21V‑301. Have spoken to the dealership as well as Hyundai corporate and they have refused to either honor their own recall campaign or do a goodwill service to replace the engine, citing my VIN does not fall under their recall campaign, however they have yet to provide any reason, and according to their own campaign 203 recall information my vehicle meets the exact criteria. I am concerned the recall population may exclude vehicles suffering the same engine defect, and their clearly is a clerical error or something on their behalf, and they appear to not be interested in remedying it, which could and has in my case resulted in potential danger. My car died in the middle of [XXX], and had I been in heavy traffic and could not have coasted it down a hill to a parking lot almost certainly would have resulted in a collision. I was fortunate enough to at the time be in light traffic. Upon restarting car motor made a horrendous knocking noise, which is symptomatic of exactly what recall campaign 203 warned of with the defective engines they installed in my series of vehicles. Hyundai denied goodwill solely based on time in service and mileage rather than identifying a different failure mechanism, and as of the time of writing this has not provided an explanation of why according to them my VIN doesn't fall in their campaign, when clearly it should as it is the correct year, correct factory stock engine, correct place if manufacture, and the very same symptoms they published in their campaign. They have told me I need new engine, as was obvious by the fact it's disabled and sounds as if a rod has thrown. I have brought this to their attention every day for going on 2-3 weeks.

At 86,000 miles After replacing the camshaft and timing chain with a mechanic friend, we turned the engine over and heard the beginning of an engine knock, he said this engine is notorious for knocking and failing before 100000. Kia recalled the exact same engine. However Hyundai did not. I feel this is very unsafe.

2019 Hyundai Elantra (VIN: [XXX]) suffered engine failure at 152,061 miles — abnormal knocking, loss of power, towed to Clay Cooley Hyundai of Sherman, TX. Diagnosed with crank/rod knock requiring long block replacement. This is the exact failure progression documented in the federal safety agency Recall 21V301 (Hyundai Recall 203): defective piston oil rings causing cylinder bore scuffing, accelerated oil consumption, connecting rod bearing failure, and engine block damage. Coverage was denied solely due to mileage — 2,061 miles beyond the 150,000-mile threshold. I am also reporting a critical discrepancy: a VIN search on the federal safety agency's website shows zero open or unrepaired recalls on this vehicle, despite the following facts: 1. This is a 2019 Elantra with a 2.0L Nu MPI engine — the exact population covered by 21V301. 2. The vehicle experienced the exact failure mode 21V301 was issued to address. 3. The dealership repair order references TSB 25-01-054H (tied directly to Recall 203) and performed an ECM software update under that bulletin during this visit. It is unclear whether this VIN was improperly excluded from the recall population, or whether the recall was marked remediated based solely on the software update — despite the engine already having suffered catastrophic internal damage. Either outcome warrants investigation. I am requesting the federal safety agency examine whether this VIN should have been included in 21V301, and whether Hyundai's practice of applying a software update to an already-failed engine and closing the recall is consistent with the intent of this safety recall. Repair estimate: $9,245.58. Vehicle is undrivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

my car was going uphill and would only go about 15 up hill and would not accelerate, no lights came one to indicate any issues, then it started driving properly. Then after about 4 min it just died, in the middle of a busy intersection during rush hour. the check oil, engine and battery lights came on. Then after turning off car it came back on and all the lights disappeared but happened exact same way after 3 more min. Both times the lights went off. Now it trys to turn on but stalls right away and the check engine light is one. After taking to the dealer they stated that there was no oil in the engine. There are also no visible leaks to explain no oil. And 3 timing codes came up as a result of this. They conducted my routine oil change and still the codes came up and the car failed to start. In addition to all of this there is a knocking noise. I have an engine like those that have been recalled in the past but my particular VIN was not part of that recall. I have always done my oil changes at Hyundai dealer and on a regular schedule. This sounds to me like the same issue the other same types of engines had.

I own a 2019 Hyundai Elantra Value Edition . 2.0L 1999CC L4. A few weeks ago we started with really cold/snowy weather and as I’m driving I’ve noticed weird knocking sound that sounds like a Ford F250 starting up. Today while stopped in traffic with the vehicle idling, the 2019 Hyundai Elantra cut off into the battery mode as if I just have my car running off of my battery (ex: roll windows up) and all of the lights on the dash board on. I put my car on the break to turn my car off and it went back into drive mode, it didn’t shut off. I tried accelerating my car went no where, within a few minutes it did it multiple times. I called the local dealer and was informed that there were no recalls associated with the VIN. I let Hyundai Webb aware of the failure. The failure mileage was approximately 197,000.

My 2019 Hyundai Elantra sel had catastrophic engine failure at 95k. I was riding at 40mph on the highway when the engine failed. It had zero warnings lights whatsoever before it happened. I was barely even able to make it off the road. I had it towed to the dealer. They said it was a rod bearing. My catalytic converter also failed. They said I was burning oil which again had no idea I was since I didn’t smell it nor did I have an engine light. However the dealer said my vin wasn’t part of the recall.

The Knock Sensor Detection System (KSDS) software malfunctioned by failing to detect abnormal vibrations or knocking sounds. As a result, there was significant internal engine damage that caused the vehicle to seize unexpectedly in the middle of traffic on 4/10/25. The car started and abnormal noises were noted from the engine though not significant. week later, car stalled several times on interstate. Prior to the failure, the vehicle exhibited a progressive knocking noise in the engine. After seizing, the vehicle would struggle to start, idle briefly, then stall. It also randomly shut off while driving, creating a serious safety risk. The vehicle was taken to Precision Tune Auto Care, where technicians confirmed problems with the crankshaft, excessive oil consumption/leakage, and metal shavings in the oil, which they attributed to rod bearing and crankshaft wear consistent with Hyundai Campaign 203 (improperly heat-treated piston rings). Despite the KSDS being installed during the initial recall remedy, the system did not activate prior to engine failure. Additionally, no engine or oil warning lamps were illuminated. An oil change was performed at the time, but the vehicle had already burned through excessive amounts of oil since the prior change. Precision Tune Auto Care advised me to take the vehicle to Allen Turner Hyundai. At the dealership, staff confirmed issues with the engine but refused to acknowledge Recall Campaign 203, even when presented with documentation. They also failed to address the malfunctioning KSDS system or the lack of functioning engine/oil warning lamps. They were asked to perform inspection relating to piston ring and rod bearing, though refused. This situation raises major safety concerns, as my engine seized in the middle of traffic without warning. Other owners with a malfunctioning KSDS system could face the same risks, leading to sudden engine failure, potential engine fires, or serious traffic accidents.

I purchased my 2019 Hyundai Elantra from a third-party dealer (Mike Carlson Motor Company in Haltom City, TX) on [XXX]. I have kept the oil changed on a regular basis since I purchased it. At the time I bought the vehicle, I purchased an extended service warranty that was through Assurant/First Extended Service Corporation. [XXX], while out of state (over 640 miles away from where I purchased the vehicle) my vehicle started making a rattling sound from the engine. The mileage on my vehicle was 85,320. I called the warranty company and opened a claim. I was told since I was not in the DFW area and more than 40 miles from the selling dealer or any sister properties, I could take it to any shop that will accept warranty work. July 18, 2025, the vehicle was finally picked up by a towing company and taken to the mechanic. An estimate was created on 07/23/25, stating test system oil is full, has code p0304 (which I looked up and is a misfire in cylinder 4), engine knocking from rod and/or piston, will need engine. Claim was sent to warranty company 07/31/25 and was finally denied today 08/08/25. First, they said lack of maintenance however, they had copies of all receipts. Then they said denied because covered under Hyundai powertrain warranty. However, after speaking with Hyundai Customer Care, it wasn't sold PRE-OWNED CERTIFIED. Had to send proof to warranty company showing no factory warranty (sent signed SelectCertified Form signed date of purchase). Now it was denied again stating OPEN RECALL on vehicle would have to contact Hyundai. The nearest Hyundai dealership is over 1 hour or more away. I'm hoping tomorrow when I reach out to Hyundai they can shed some light on the situation. I've been stranded in Illinois (I live in Texas) since 07/16/25 and have made no head way to get the vehicle back on the road.

Vehicle Issue Report Vehicle Information: •Make: Hyundai •Model: Elantra •Year: 2019 •VIN: [XXX] •Mileage: [Insert Current Mileage] •Engine Type: 2.0L Nu MPI ⸻ Summary of the Issue: The vehicle has experienced a complete engine failure due to a malfunction in cylinder 3. The issue began with noticeable performance problems including rough idling, knocking sounds, and a check engine light. After diagnostic evaluation, it was confirmed that the engine has failed, and a replacement is necessary. ⸻ Cause of Failure: The root cause of the failure has been traced to cylinder 3 misfiring and loss of compression, which led to severe engine damage. Based on known technical service bulletins and recalls issued by Hyundai, this failure aligns with existing recall campaigns related to improperly heat-treated piston oil rings in the Nu MPI engine. These rings can cause oil consumption, scoring of cylinder walls, and eventual engine failure. ⸻ Recall and Warranty Consideration: Given that Hyundai has issued multiple recalls and extended warranties for this exact problem in 2019–2020 Elantra models, we are requesting that this vehicle be covered under Hyundai’s engine replacement recall or extended Powertrain Warranty (up to 150,000 miles / 15years) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
