Vehicle is burning 1.1 quarts of oil every 1000 miles

My 2018 Hyundai Elantra GT (2.0L Nu GDI engine) has completely shut off while driving on three separate occasions: approximately June 2, 2026 (first occurrence), June 23, 2026, and September 14, 2026. The stalls happened on the highway at highway speed, while pulling into a parking spot, and on a public road at a stoplight. Immediately before each stall, all dashboard warning lights illuminated, then the engine died without further warning, causing sudden loss of power steering and power brake assist and making the vehicle extremely difficult to steer and stop. The vehicle also consumes engine oil at an extreme rate: after a full oil fill, the dipstick showed no oil within about two weeks (documented on video, September 30, 2026). An independent repair shop serviced the vehicle four times in 2026 for the same unresolved problem ($1,322.48 total), documenting diagnostic codes P0017, P0341, and P0366 and noting no oil leaks; the June 23 and September 14 shop visits correspond to two of the stall dates. This engine family is covered under Hyundai's Engine II class action settlement (2014-2020 Elantra GT, Nu 2.0L GDI) for connecting rod bearing failures that cause stalling and engine seizure. The Hyundai dealer proposed a 1,000-mile oil consumption test requiring continued driving of the vehicle, which I declined as unsafe given the repeated sudden stalls with loss of steering and braking.

The oil consumption appears similar to issues reported in recalls and investigations involving Hyundai engines; Hyundai and Kia Engine Litigation II. However, when the VIN was checked, it was reported as not included in any recall. No external oil leaks have been identified. The component available for inspection is the engine and related lubrication system. Prior to discovering the excessive oil consumption, there were no warning lamps, messages, unusual noises, or other symptoms. The issue was first noticed when the oil level was found to be significantly low despite regular maintenance and no evidence of leaks. The cause is believed to be internal engine oil consumption. UNKNOWN whether the manufacturer has inspected the vehicle. Additional inspection and investigation are requested due to the similarity of this condition to known Hyundai engine oil consumption complaints.

The vehicle is experiencing excessive engine oil consumption. The engine burns approximately one quart of oil per week during normal driving conditions. There are no visible oil leaks, and no warning lights, check engine light, or other dashboard messages have appeared. The oil level drops rapidly between oil changes and requires frequent topping off to prevent the engine from running low on oil. This condition creates a safety risk because the engine could suffer sudden damage, loss of power, or engine failure while driving if the oil level becomes too low. The problem has been ongoing and is reproducible.

The vehicle is experiencing engine-related excessive oil consumption, which has led to failure of the catalytic converter and emissions system. The root issue appears to be an internal engine defect causing oil to burn during operation. Yes, the vehicle is available for inspection upon request, including the engine and catalytic converter components. The excessive oil consumption creates a risk of engine damage or sudden engine failure while driving, which could lead to loss of power in traffic. Additionally, a failing catalytic converter can cause reduced engine performance, stalling, or overheating, increasing the risk of unsafe driving conditions, especially on highways or in heavy traffic. Yes, the issue was previously reported to a dealership, including concerns about excessive oil consumption. The problem has continued and worsened over time, now resulting in a check engine light and catalytic converter-related fault codes, confirming the ongoing condition. The vehicle has been inspected by a dealership service department in the past regarding oil consumption concerns. At this time, it has not been inspected by police or insurance representatives. Further inspection by the manufacturer or authorized dealership can be conducted upon request. Yes, symptoms began with excessive oil loss requiring frequent top-offs, followed by the appearance of a check engine light. The issue was first reported approximately one year ago and has progressively worsened, ultimately resulting in catalytic converter-related fault codes and continued oil consumption.

I've contacted Hyundai to try and do a recall repair on my Hyundai Elantra GT 2018 both through a local dealership (Planet Hyundai in Golden, CO) and Hyundai corporate. The engine is stalling and knocking very bad to the point where it's no longer drivable. It's burning oil non-stop and I am constantly adding oil to it. I'm getting pushback from Hyundai saying I never fixed the recall when I was actually not notified to begin with. I'm the 2nd owner of the car so if I was never notified, how can I be responsible for something I was never told about? Now they are saying this little sensor was supposed to help let you know there's a problem with the engine (sounds like a check engine light?). Hyundai has known about their engines being faulty for quite some time. I need this vehicle to get to and from my job as well as taking my grandson to multiple doctor's appointments each week because he has a disability (he's only [XXX] old). They need to take responsibility for this. Is there anything the federal safety agency can do? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In mid-2024, the vehicle experienced a flashing check engine light. I brought it to Murfreesboro Hyundai (TN), where they confirmed the oil was low and started an oil consumption test. A bearing clearance test (BCT) was also performed and passed. After back-and-forth over several weeks, I was told the oil consumption was within spec, but the dealership stated Hyundai would cover all necessary repairs, including a combustion chamber cleaning, under warranty. I was told this work was completed and the vehicle was returned to me. In July 2025, the exact same flashing CEL returned. I brought the car back to the same dealership, where they again found the oil was 2.5 quarts low. However, this time they claimed no previous combustion cleaning or repairs had been done, and that I would now need to pay over $1,100 out of pocket for the same cleaning that was supposedly already performed — and which they had told me would be covered under warranty. This indicates that the dealership misrepresented completed service work, failed to address a recurring defect, and is now trying to shift the financial burden to me. Hyundai’s claim that oil consumption is not “high enough” to warrant coverage is concerning, especially when the condition continues to damage the engine and cause driveability issues. This appears to be part of a broader known defect affecting Hyundai 2.0L engines. I am requesting that the federal safety agency investigate Hyundai’s handling of oil consumption, engine misfire, and warranty practices related to the 2018 Elantra GT and similar models.

The engine burns oil quickly which could lead to the engine blowing. I have to get more oil changes than average to the engine burning oil.

The engine is consuming excessive oil. The car has about 72k miles on it and I’ve owned it for almost 4 years. I called corporate Hyundai to tell them what’s going on after having multiple recalls fixed at the dealership, I was allowed to drive off the lot with no oil in my vehicle. Upon getting an appointment for the engine issue via corporate Hyundai, I was told to they would have to keep my car but have no loaner vehicles for me because they’re all out of commission for engine issues. I shortly received a call from them saying the engine isn’t covered under warranty and that they have to do a $942 cleaning and then if that doesn’t work, I need a new engine and Hyundai will do nothing to help me with this because I am not the first owner. I bought the car from a Hyundai dealership.
