general problems of the 2019 Hyundai Elantra - part 1

The contact owns a 2019 Hyundai Elantra. The contact stated that while stopped in traffic with the vehicle idling, the vehicle vibrated, and the check engine warning light illuminated. The contact stated that for the rest of the drive, the vehicle failed to accelerate as intended while depressing the accelerator pedal. While the contact was entering a driveway, the vehicle stalled. The contact waited for several minutes before being able to restart the vehicle. The contact then drove to the residence. The vehicle was taken to an independent mechanic, where it was diagnosed with engine failure. The independent mechanic informed the contact that the engine was making an abnormal rattling sound and the piston oil ring had failed. The vehicle was not repaired; however, an oil change was performed. The contact called the local dealer and was informed that there were no recalls associated with the VIN. The manufacturer was not made aware of the failure. The failure mileage was approximately 126,000.

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.

Yes, it put people at risk by breaking the engine and throwing oil on the highway. The engine simply opened a hole in the block. There was no light and yes the car is currently in inspection at Hyundai focus on these cars because Hyundai complicates a lot to try to get out of warranty.

In or about December/2022, I had made numerous attempts to fix my vehicle's engine. It kept stalling on the roadway and finally Hyundai agreed the motor was the problem and they ended up installing a new motor. The vehicle was then out not warranty and they said they were not responsible for the vehicle any longer. The vehicle's check engine light kept coming on and off at times. I did minor work to the vehicle and kept up with maintenance. Now my vehicle's motor is blown again without notice. It stalls on the highway and leaves me stranded. I believe that this type of vehicles were flawed from the beginning. I really convinced these vehicles should be recalled and taken off the highways since, in my opinion, they are not safe to be on the road.

The component that failed was the pistons in my engine on my 2019 Hyundai Elantra se which I see is on recall. I understand that my VIN may have been missed or looked over during the recalling systems decision making. I was on my way to work when my engine just shut off in the middle of traffic! since that happened my anxiety levels has been extremely high! I took my car to the dealership and they confirmed that it was my pistons and to keep checking the recall website because they have seen something like this before. Before the engine cut off there was abosulutly no warning! date of incident [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2019 Hyundai Elantra. While the contact’s daughter was driving at an undisclosed speed, the vehicle stalled. During the failure, the check engine and oil warning lights were illuminated. The vehicle was later towed to an independent mechanic and was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The contact was informed that the VIN was not included in NHTSA campaign number: 21v301000 (engine). The contact stated that the vehicle had experienced the same failure listed in the recall. The failure mileage was 130,000.

The car turn off in the middle of the road and it ain’t wanna turn back on and I had cars behind me and almost hit the back of my car my emergency light were on too and I was in the city I had to get it towed.

I purchased my 2019 Hyundai Elantra from a third-party dealer (mike carlson motor company in haltom city, TX) on may 30, 2024. 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. July 16, 2025, 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.

Car began to make clicking noise which turned into a louder “dying” sound. Car completely stopped, and had to get towed. I was told the engine failed due to parts from the recall.

My vehicle is a 2019 Hyundai Elantra. It has the Hyundai nu 2. 0l engine, which has been the subject of recalls for engine failure, stalling, and sudden loss of power. The check engine light came on but not before the majority of the dangerous driving conditions surfaced, meaning I had almost no warning before the issue put my life in danger. My vehicle was not included in the recall even though other models with the same engine had been. I experienced unpredictable stalling, hesitation, and engine failure while driving. On several occasions, the car stalled unexpectedly in traffic, creating a serious safety risk; I nearly was rear-ended multiple times. The vehicle became increasingly unreliable, prompting me to take it to the dealership. The dealership confirmed that the engine failure was consistent with the known nu 2. 0l engine defect. There was metal debris in the oil even though I have kept up with maintaince and oil changes at the regular intervals suggested by Hyundai guidelines. Hyundai covered approximately 90% of the engine replacement under a “good faith” adjustment. Documentation of engine inspection and repair available upon request.

The contact owns a 2019 Hyundai Elantra. The contact received notification of NHTSA campaign number: 21v301000 (engine); however, the part to do the recall repair was not yet available. The contact was stationed in guam when the vehicle was purchased. The vehicle was manufactured in south korea. The contact then moved to the USA, and the vehicle was taken to colorado however, the vehicle was registered in florida. The dealer was contacted and refused to repair the vehicle, because the vehicle was considered a foreign vehicle. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Large amount of oil consumption. Told by dealership that engine replacement is needed.

Excessive oil consumption, shudder in motor while driving . Check engine light cam on. Visibility in headlights very low and high beams only working sometimes.

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.

My car started hesitating when shifting gears in Smart and normal mode smelled like something was burning. Car only drives in sport mode, shifts hard, engine lags, and the check engine light has not come on. This is the second incident with this car. The first time I lost all power to the car and the entire electrical system shut down, when it was towed to the dealership they said nothing was wrong with it. I keep up on all the maintenance.

On 03/22/2025, I took my car into riverside Hyundai because of engine shuttering. Riverside Hyundai discovered foreign fragments in my cylinder from the piston and stated they had never seen this issue before. Their diagnosis was engine replacement at an estimated cost of approximately $7,500 for the engine and $3,168 for labor for a total amount of $10,668. Searching for answers, I quickly came across the Hyundai Elantra piston defect class action lawsuit (brown v. Hyundai motor America), which pertains to an engine piston defect not properly heat treated affecting the same year and make of my 2019 Hyundai Elantra. The class action lawsuit related to a defect found in certain Elantras equipped with nu 1. 8l engines. Although this defect is specifically tied to issues within the pistons, which are a critical component of the engine responsible for generating the force necessary to power the vehicle. The defect can ultimately result in “total and irreparable engine failure. ” this failure leads to a loss of engine power, power steering, and brake assistance, all of which pose significant safety risks. While this class action suit has settled, and is an important step in addressing the engine defect that has already impacted many vehicle owners, I believe that the scope of the class action lawsuit was not broad enough, as it failed to include all vehicles that could potentially be affected by the same or similar defects, specifically Hyundai Elantras with different engine types, like the one in my 2019 Hyundai Elantra. Although my Elantra is equipped with a different engine, I believe that the defect that was present in the class action suit, is the same defect that caused this damage to my engine. I also came across images of the defect online which seem identical to damage caused to my engine. Please see attached files for your review. Riverside Hyundai has denied my request for a good faith replacement engine and are still waiting on a reply from Hyundai.

No warning light for oil consumption and it depletes rapidly. Also, high beam lights stopped working and you have to hold the signal in place and the high beam still doesn't turn on. Ive had so many issues with this car since purchasing it, it ridiculous and saddening how there hasn't been any recalls and the issue before this one was dangerous and life threatening. Also, since it's purchase it consumes oil at a rapid rate that has been documented and each time I've visited the repair shop they informed 'there's no oil' in the vehicle and no oil light or anything comes on to warn me. I find out about it because of an entirely different issue needing to be fixed.

The engine seized up completely and the car would not start. The car ran fine prior to this on the same day and there were no warning lights or warnings when a portable code reader was plugged in to assess the problem. It was towed to a mechanic who said it looked like excessive oil consumption as the oil was changed only 6 weeks prior and the level was assessed to be perfect then. This is a safety risk due to the engine seizing without warning. If this were to happen while driving, it could cause a fire or cause the driver to be stranded on a busy road, causing accidents. The car is being looked at by a Hyundai dealer currently.

For the now 2nd time for the same problem as before, I was on the highway and the car just cut off mid drive on 8/17/2024 @70mph!! engine light came on. Later that day while on the street, 35-40 mph, all of a sudden no engine light on. . . The car cuts off again mid drive!! I purchased the car with roughly 15k miles on it and it's been absolutely nothing but issues back to back. The daytime running lights constantly blow out also. The shop supposedly repaired this issue when I put it in the shop the first time, but it's doing the exact same thing again.

All service has been done only at westside Hyundai of jacksonville. The car is now at harvey Hyundai of louisiana waiting to hear from westside Hyundai.

My engine is burning oil at a rapid rate. I have always maintained the vehicle's engine on-time or early and now I am needing to top-off oil many times between frequent oil changes. I am now having to add a quart a week and am changing the oil every two thousand miles to ensure it is clean. This is not regular or okay and two mechanics/service technicians said that many Hyundais that come in are doing the same thing.

My vehicle will randomly stop driving and then might be fine. The check engine light has been in for over a year and the dealership says it leaks oil and builds up sludge when we were only taking it to them. When checking the code for the check engine light it says it’s the cam shaft sensors. The dealership said it was fine and cannot figure out why there is a light or why it stops driving. Last night it was sputtering when breaking and then when turning.
