2020 Hyundai Elantra: excessive oil consumption

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.

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.

Engine is stalling and consuming oil at a higher then normal rate. Knock sensor is having issues at 24k miles both part of recall campaign 974 and recall 203. Took the auto to dealer for service and was told Hyundai would not honor the recall due to a branded title which now puts me in a scenario of possibly engine stall in the middle of highway traffic.

At around the 120K mile odometer reading check engine light came on and upon checking the oil, noticed it was 1/2 qt. down in spite of a recent oil change. There were no other issues apparent to our mechanic. At the next oil change, we asked the techs to be sure to tighten the oil pan and all components as we mentioned the drop in oil after the previous oil change. This time, only 10 days after the oil change (we have been using hybrid blend since purchasing the vehicle new), the check engine light went on again and the oil was down a quart with no signs of leaking. Our mechanic checked it again and told us of many Hyundai oil consumption issues and suggested we check for a recall. My vehicle was not included in the oil consumption recall despite having the same year, model and engine as many of the other "certain" vehicles. We are currently negotiating a solution with Hyundai Motor Corp.

Burning oil at any unacceptable rate. I have made sure to have preventative maintenance and oil changes done every 3K miles. Hyundai needs to address this problem that appears to be plaguing many drivers.

Engine failure: Engine light came on and oil level was abnormally low, even though oil had been changed not long before. Before able to add buy more oil to add when checked, the engine gradually lost pressure and wouldn't stay started. Died in the middle lane of highway all of a sudden. Inspection under hood showed that there was oil all around on engine and some on the ground. Towed to dealership and was not told of interim recall 21V‑301. Possible acceleration of engine oil consumption due to bad piston oil rings. Later I researched and found that Hyundai was to inform owners that they were encouraged to check the level of oil periodically between oil changes...that accelerated oil consumption was possible due to this issue of the oil rings. Had to research and find myself.

The component which failed was the engine. This engine has been burning oil from the day in which we bought it. This engine puts everyone at risk because it failed in the middle of traffic, and We could have been hit by oncoming traffic. The problem could not be reproduced because the engine tied up in the middle of the road. We had the vehicle towed to the dealer who said it was not covered under the warranty due to abuse. The oil had been changed at the proper intervals, and we are sure the engine failed because it was a poorly made engine. This engine had exactly 69,993 miles when it tied up. We attempted to have it repaired at 54 thousand miles but the dealer said we need more money to check it out, but when they sold it they said the engine was covered. When we brought it in we asked for a loaner, but initially they refused. Three weeks later, we demanded a loaner as we happen to see the owner Steve Taylor at the customer service desk and he complied. After a month and a half without our car getting repaired they said we did not change the oil at the proper intervals, and said we need receipts for every oil change. We have a fully equipped auto shop in our steel-frame barn in which we replace engines for our Cars-for-Christ fundraiser program, and completed all the oil changes through our own mechanic. Before we could retrieve our purchase our oil purchase receipts they said, Hyundai will not replace this motor and it is not covered, we can put another engine in your car for 10,000 dollars. We still owe 14thousand on this car, and 4 thousand of that was for the 2017 Sonata which we bought that failed and we had to trade that to buy this 2020 Elantra. I have read all the complaints on these engines and they are OIL BURNERS. We put full synthetic oil in this engine and before it was time to change the oil, it was out of oil. We had to constantly put oil in this car about 1.5 to 2.5 per month. Now, we must replace this engine and pay 14k? HELP!!!!!

The vehicles engine has gone through a gradual decrease of power and then the car went into "Limp mode" and began burning oil. I have taken it to dealer multiple times and they would run diagnostic and never find anything significant. When it went into limp mode I took it back to dealer and they ran diagnostic and said the engine was bad. They said that the car is out of warranty and they would not cover the repairs. When I look into the problems that the vehicle was exhibiting there was a recall 203 that describes my problem exactly. When I look it shows this was completed at around 6000 miles. I believe this was done to early in the vehicles life and it didn't exhibit any of these issues. Now at 80,000 miles the engine now has all the issues described in the recall and the manufacturer will not replace or repair the engine
