2019 Hyundai Elantra: sudden loss of power

Filed Jul 6, 2026 · Engine · NJ

While driving vehicle on a highway exit ramp, the engine suddenly failed. There were no warning lights, messages, noises, or other signs before it happened. The vehicle lost power and became undrivable, which was scary and dangerous because I was still on the road near highway traffic. The vehicle had to be towed to the dealership. The dealership inspected it and said the engine had failed. I was given a repair estimate of about $9,100. I was also told the repair would not be covered under warranty and would not be covered under a recall. I believe this is a serious safety issue because the engine failed without warning while I was driving. If this had happened at a different time or location, it could have caused an accident or put other drivers at risk. The vehicle is currently undrivable, and the failed engine/component is available for inspection upon request

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 2019 Hyundai Elantra with the 2.0L engine experienced sudden engine failure at 164.809 miles. The check enqine light came on and the vehicle immediately lost power and shut off. 0i was visible in the wheel well and the engine now has a tapping noise suggesting internal damage I understand that Hvundai recalled certain 2019 Elantra models due to improperly heat-treated piston oil rings that could cause engine damage. Because the symptoms of my failure match this defect, I am requesting Hyundai review this as a potential defect-related enaine failure and consider goodwill assistance or engine replacement.

The engine in my 2019 Hyundai Elantra failed at approximately 66,000 miles. The vehicle began to idle roughly, lose power, and eventually stalled and would not restart. It was first inspected by an independent mechanic, who suggested a possible electrical issue. I then took it to a Hyundai dealership, where they later confirmed the engine was blown due to internal failure. I had a new warranty after refinancing, which required the car to be driven a minimum number of miles before coverage could be used. The engine failed when I was only a few miles short of that requirement. The warranty representative from the refinancing company confirmed in a voicemail that while they could cover work already completed (fuel pump), they could not cover the engine. The Hyundai technician also recommended returning the vehicle to the dealership for a new engine. The dealership had previously noted the vehicle was only a few miles outside warranty coverage and even suggested they could “drive the car a few miles” to make it appear within warranty , they said after they put the part in , it drove 3 miles and the engine gave out . They charged approximately $2,000 for a repair that failed, and the vehicle was never drivable again. Because the vehicle did not operate and I could not continue payments, it was repossessed. The loan balance I now owe is a direct result of the premature engine failure and unsuccessful repair. I later learned that 2019 Elantras with 2.0L Nu MPI engines have recalls and complaints regarding improperly heat-treated piston rings causing engine damage. My VIN did not initially show under recall, but this failure matches known defect patterns. There were no warning lights prior to failure; the engine failed suddenly. I believe this vehicle should qualify for recall or warranty coverage.

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

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.

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.

I was going 40MPH when my car started to produce loud noises and stalled. It immediately lost power and I had to pull over on the side of the road. It started back up after 30 minutes and I was able to drive it home, but it continued to make loud noises and I had to drive very slow. Battery is good with 70% charge and the alternator is good.

High beams quit working I. Weather conditions and now high beams don’t work period and have to replace head light do to problem with assembly driver side and passenger side high beams don’t work. Vehicle engine light came on and vehicle started driving rough at times stalling while driving it. Took it to a mechanic after replacing all coils plus spark plugs vehicle still showed engine light on. It also diagnosed sensors and cam shafts, solenoids. After all work performed vehicle engine light was still on and was driving rough at times still stalling on the road. The car would stall constantly with out warning. Sometimes will start up again and sometimes it wont. Then increased oil consumption, progressing to a knocking sound, and the engine seizing and stalling. Also warning light in the instrument panel, knocking noise from the engine, reduced power or hesitation when accelerating, or the smell of burning oil. Engine shut off while driving. Now car won't start at all. Took the car to be looked at they ran all kinds of diagnostic testing, one of which came back showing my engine lost almost all compression. Bought it from dealer car was used as a rental. I am the first real owner. There was a hyndai Elantra recall for engines but I believe my car is not included and I think my car has a 2l engine. I found the information below from a search engine. "Hyundai motor America (Hyundai) is recalling 158,493 2019-2021 Elantra cars, equipped with the 2. 0l nu mpi engine".

I was driving on the interstate and suffered a sudden loss of power with a check engine light. I stalled on the interstate which is dangerous. Waited 2 minutes and started the car again, check engine came on almost immediately. Drove off the interstate and had car towed to dealer. Dealer Tony Hyundai found no oil in the car and the engine failed a bearing clearance test. The dealer serviced the engine under Hyundai CPO warranty but I am concerned that there is no root cause of the engine failure. I am reporting to the federal safety agency in the hopes that other owners who experience this will also report it and if there is a common problem it will be discovered. Additional documentation is available by request.

I was driving home from work at night when my 2019 Hyundai Elantra Sport (just found out has the wrong VIN) lost all power and felt like it wasn’t running on all cylinders. I switched it to sport mode had a little more power for about 2 mins then my car died completely. I had to pull over thankfully I made it to the bottom of the pass and coasted into a gas station while I waited for a tow truck to have it towed to the dealership. The dealership had my car for almost a week. They ran all kinds of diagnostic testing, one of which came back showing my engine lost almost all compression. Secondly they ran more tests and more tests and just to tell me it was a bad battery. The battery has been replaced. My car is still having idling issues, it’s shifting hard and the lane Assist which I kept on just the warning turns itself on randomly, same with the front assist. This vehicle has 37,000 miles on it. Maintenance has been done regularly along with the highest quality oil changes, premium gas and air filters. I AM PISSED THAT I AM PAYING SO MUCH MONEY A MONTH AND AM HAVING NOTHING BUT ISSUES.
