Hyundai Elantra GT loss of power problems

Filed Oct 1, 2026 · Engine · CA

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 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 oil consumption appears similar to issues reported in recalls and investigations involving Hyundai engines; 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 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.

While driving regular route during working hours the check engine light came on. Car was taken to a trusted mechanic who reported that the oil level was extremely low! He replaced filters and oil etc. The care then performed for less than a day when again the check engine light came on, flashing this time. Again took car to mechanic who found metal shards in the new filter, replaced same and added oil stabilizer. Again the car ran for only a few hours before it begin making knocking noises and lost power. Mechanic believes the engine has failed completely and will need to be replaced or that we will need to replace the car.....a problem as there is a considerable balance due on said car. Car was purchased used in September 1922

my vehicle with apparently refurbished engine was purchased certified used through carvana in 2019 & was one of the recalled vehicles from 2017 (which I was NOT informed of at them of purchase)and is exhibiting the same signs as those in the recall, loss of power at acceleration, vibrating, etc & my local dealership, Doug's Hyundai of Edmonds is refusing to service my vehicle. I don't feel safe driving further to another dealership

The contact owns a 2014 Hyundai Elantra. The contact stated while driving down a hill at 10 MPH, various warning lights illuminated as the vehicle lost all power. The contact stated that the brakes and steering failed as the vehicle rolled down a hill and stopped at the bottom of the hill. The contact stated that she was able to restart the vehicle after 10 minutes, resuming normal operation. The vehicle was taken to an independent mechanic who was unable to diagnose a failure. The contact then took the vehicle to another independent mechanic who performed diagnostic testing and no failure codes were detected. The contact then continued to drive the vehicle however, 3 weeks later the failure reoccurred. The vehicle was then taken back to two independent mechanics where no failure was determined again. The contact stated that the failure occurred a third time while driving up a hill with the vehicle losing power. This time the vehicle was unable to restart without a jump start. The vehicle was taken to the dealer where the contact informed them of excessive oil consumption and the loss of power failure. The dealer informed her that an engine diagnostic was not performed as no warning lights were illuminated. The contact stated that the dealer performed an engine combustion cleaning. The manufacturer was notified of the failure and informed the contact that the VIN was not included in any recalls. No further assistance was offered. The approximate failure mileage was 104,000. The consumer stated she spent almost $1,000 to rectify the oil burning issue with the dealer, but doesn't know whether the problems has been resolved.

driving down highway 50MPH, car completely lost power. Could have run off road due to loss of power steering, could have been hit, Got looked at by Ruddell dealership in port angeles wa where it was purchased, has a seized motor, not due to lack of oil. based upon research on the internet, this is a common issue at around 60-80K miles with this year make model. especially considering the fact that Hyundai just settled in october of 2020 for motors seizing without admitting fault, I believe they are still producing faulty motors. they have also since discontinued producing this motor, so I cant get a new one from the factory. it was dark, and I could have been ran into, or rolled off the road.
