Hyundai Elantra oil consumption problems

Filed Oct 7, 2026 · Engine · CA

2020 Hyundai Elantra, VIN [XXX], ~79,239 mi. On or about [XXX], while entering a parking lot at low speed on an incline, I pressed the accelerator but the car had severe power loss and then stalled. It would not move in reverse. All dashboard lights came on only after the stall. I restarted it; the lights cleared. It was towed to Westlake Hyundai, 3610 Thousand Oaks Blvd, Thousand Oaks, CA 91362; checked in Sep 29, 2026 8:59 AM. Dealer found engine oil below the low mark, no external leaks, DTCs P0302/P0304 (misfires cyl 2 & 4), and all spark plugs worn/fouled. They replaced the plugs and started an oil consumption test per TSB 23-EM-008H. Critical safety issue: the oil pressure warning light never illuminated before or during the stall, despite critically low oil. This removed my only warning to pull over safely. A sudden stall in traffic could cause a crash. The vehicle has the 2.0L Nu MPI engine covered by Recall 21V301 for defective piston oil rings causing excessive oil consumption and engine failure. My VIN is not included, but it shows the same failure. Vehicle is available for inspection. No police/insurance inspection. Manufacturer not yet inspected. Concern: engine defect and oil pressure warning system failure. Attached: Westlake Hyundai repair order/inspection.

Back in early July, I noticed a ticking sound coming from my engine so when I took it in to a Hyundai dealership, they told me the only way I could pursue any help further was by completing a oil consumption test, which I complied and paid for out-of-pocket very soon after within 48 hours my check engine light came on and was flashing. after pulling the code at an AutoZone which I have documentation of it was a P 1327 which signals that the car had entered limp mode. I very quickly reached out to Hyundai themselves and after going back-and-forth on paperwork, they assured me that since I had no coverage on the vehicle due to its mileageand that it was not produced in the same factory as the other recall vehicles with that same problem that they could not pay or help me with any of the services I would need done to my engine. They told me the only chance I had was by completing the oil consumption test, which would then put me and my safety at risk by driving a car with a faulty engine while it was also in limp mode. I’ve only had the car for about a year and a half when it threw the first sign at me and I’m now struggling to figure out how to afford a completely new engine all on my own with no financial assistance all because my car was not made in the same factory as all the other ones that have had the same issue. I have not been able to drive the vehicle in the last two months and it just put me into financial deficit, trying to figure out reliable transportation to get to my current employer. It also states that the previous owner must have had an engine inspection/replacement but was not specified of which specific action was taken on the official Hyundai website.

Component: Engine (oil intrusion cylinders 1, 2, and 4). Vehicle currently at Stevens Creek Hyundai, available for inspection upon request. Safety risk: Large volume of smoke while driving, reduced visibility, and risk of further engine damage while unresolved. Reproduced/confirmed: Yes. Independent mechanic (Liberti's Automotive, 7/13/26) documented oil entering cylinders 1, 2, and 4. Dealership's own inspection gave inconsistent findings after one week delay saying they do not have the tool to look at the engine, a week later first stating cylinders 1-3 "looked okay" with cylinder 4 unable to be checked due to a broken connector, later stating the engine looked "clean," then offering two conflicting theories: a possible fuel injector issue or an oil consumption issue requiring a 1,000-mile test, despite earlier being told the test wouldn't be needed since oil was already documented. Inspected by manufacturer: Yes, by authorized Hyundai dealer (Stevens Creek Hyundai). Not inspected by police or insurance. Warning lamps: None reported prior to the smoking incident. No written diagnostic report has been provided. Repair estimates: $6,000-$10,000 for the engine by depending on mechanic, $2,000 for the fuel injector by Dealer— far exceeding the vehicle's value ($2,900 CarFax, $500 as-is per dealership). Concerned this vehicle, despite completing the engine monitoring recall, still developed oil intrusion consistent with known Hyundai engine defects. Vehicle sat at dealership for over a week without a clear diagnosis or determination, remaining in an unresolved safety state longer than necessary.

I bought my 2017 Hyundai Elantra SE earlier this year with about 119,000 miles. It had good maintenance records when I bought it, and it now has about 128,000 miles. Since buying it, I've had two oil changes done along with new spark plugs, coils, front brake pads, and tires. About two days before the engine failed, I noticed the car had suddenly burned through a significant amount of oil. There was no visible oil leak. The car stopped running, so I had it towed instead of continuing to drive it. Oil was added, and afterward it started and seemed to be running fine.The next day, I was driving approximately 70 mph on the interstate when the car suddenly lost acceleration and warning lights came on. There was smoke while I was driving, including smoke/fumes coming into the car. Afterward, there was oil everywhere. The car had to be towed again and is no longer drivable.What concerns me most is how quickly this happened. The car went from suddenly consuming oil with no visible leak to losing acceleration and experiencing a major engine failure while I was traveling 70 mph on the interstate. Losing power at that speed was dangerous, and the amount of oil and smoke also made me concerned about the possibility of a fire. Hyundai has told me the vehicle is no longer under warranty. I have not paid for an extensive engine teardown yet. My grandfather looked and he said it appears the engine threw a connecting rod through the side of the engine block. With the valve cover off, the engine looked brand new. I'm filing this complaint because an engine suddenly losing power at interstate speeds, along with oil and smoke, is a serious safety concern, especially with the potential for a fire. I hope the federal safety agency will compare this incident with other complaints involving engine failure and excessive oil consumption in 2017 Hyundai Elantras. Currently, it's available for inspection.

The vehicle entered limp mode. The Hyundai dealer diagnosed a camshaft problem, said the repair would be covered, ordered the part, and began the work. After the engine was opened, the dealer noted sludge/varnish and denied coverage, claiming lack of maintenance. This VIN is included in safety recall 21V301 for improperly heat-treated piston oil rings on the 2.0L Nu MPI engine. Hyundai told the federal safety agency that chipped rings can scuff the cylinder bore, cause accelerated oil consumption, knocking, oil-pressure warning, connecting-rod bearing seizure, stall, and in limited cases fire. The published remedy is inspection of the cylinder bore and piston skirt, engine replacement if damage is found, and PNSS software, at no charge. Hyundai National Consumer Affairs Case #XXX. I sent a written demand that they complete Campaign 203 and not convert an open safety recall into a customer-pay job. On XXX, case manager Mohammad issued a letter denying only “limited warranty” coverage for lack of Owner’s Manual maintenance. That letter does not state whether the Campaign 203 bore/skirt inspection was done, does not state whether PNSS was installed, and does not decide the incomplete recall. Oil and filter were changed on a regular schedule by the owner’s family using the specified oil. A signed affidavit was provided. Hyundai’s warranty does not require dealer-only oil changes. The symptom of the recalled oil-consumption defect (varnish/sludge) is being used to refuse the recall remedy. The vehicle remains unrepaired. I have not authorized customer-pay work or disposal of parts. What I want the federal safety agency to do Record this as an incomplete recall remedy. Require Hyundai Motor America to complete Campaign 203 on VIN [XXX]: perform the official bore and piston-skirt inspection, replace the engine if abnormalities exist, install PNSS, and cover related camshaft/engine damage found when the engine was opened, at no charge.

The engine failed for my 2019 Hyundai Elantra. We bought it at Atlantic Hyundai dealership. They used a passing recall inspection to clear a defective engine, misdiagnosed the ensuing failure as an oil pan leak, and abandoned me with a vehicle that stalled dangerously in traffic. We brought car to Atlantic Hyundai told them that the car just stopped on the highway in the middle of driving. Our mechanic told me to tell Hyundai the car was rapidly consuming oil. Hyundai said oh no it’s just an oil pan snd we trusted them allowed them to fix it. Several weeks later the car completely stopped in middle of driving on exit ramp. Police came to make sure traffic was diverted so they could help me get car to side of road safely. It was towed back to my mechanic who said same exact thing car is dangerous bring it to Hyundai they need to fix this for you it’s the engine recall. We had it towed to dealership and after 2 weeks they said oh yeah you need new engine. We brought it to independent mechanic because Atlantic Hyundai knowingly sent me off in a dangerous vehicle the first time and no longer did I trust them with safety of myself and others on the road

The car was driving on the highway and out of nowhere the car just stopped in the middle of the highway. I brought it to my mechanic who said the car was rapidly consuming oil and my cars engine was seizing. and he safely brought me and the car to Atlantic Hyundai where I had bought the car to have them diagnose and fix the issue. After several days they diagnosed the issue as a simple oil pan issue and replaced the oil pan and sent me on my way. The same issue with the engine seizing up in the middle of driving on the highway endangering my life and others. I am still terrified thinking of this. We brought car back to Hyundai by tow truck because I was scared to drive it and after 2 weeks of waiting they then told me the car needed new engine however they never mentioned what I later discovered was a serious recall for this specific engine . Upon further research my car was listed under the recall however before I bought the car it says it passed the test to see if it needed engine replacement under recall 203 . They knowingly said my vehicle was safe they sold it to me knowing it was unsafe and then they put a bandaid ( oil pan) and sent me on my way knowing I was in danger. I am lucky to be alive because the car stalled out on a major highway .

Engine burned oil and had knocking sound, despite having regular oil changes. Stalked out while driving took to dealer initial said it was covered by the exerted coverage but ultimately denied. It had 111,000 miles on it. I believe this engine has the same issues as the others.

I purchased the vehicle from a private party on 8/18/21 with 38,310 miles. Almost immediately after owning the vehicle I noticed the engine oil level was low.. The owner had said she had just got an oil change so I thought maybe the shop just left it low. Then I noticed it low again a month later, and that was the start of my nearly 5 year journey of having the carrying quarts of oil in the trunk of my car because the engine was burning the oil so quickly. Finally on 5/08/26 the car begins to run very poorly, long story short my personal mechanic and Hyundai of Ontario both confirm the engine is bad and needs to be replaced. I understand there is a history of this year of Hyundai engines burning excessive oil. The car currently has 92,362 miles and even though it’s under the 100,000 warranty Hyundai says the warranty is only offered to the original owner. Any help you can provide to determine if Hyundai has any liability related to this issue would be much appreciated.

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)
