2014 Hyundai Elantra: excessive oil consumption

Filed Sep 28, 2026 · Engine · CA

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.

The engine in my car (Hyundai Elantra gt 2014) basically did everything I read about all the other Hyundai engines doing that are under engine recalls. Years ago it started having misfires, had the catalytic converter or parts of it replaced, sensors, over consuming oil, loud noises when it's lower on oil and eventually it just recently died. Unfortunately it's only 11,000 miles over the extended warranty period to get it replaced. The bad engine stuff basically broke the current catalytic converter and the dealership wants over 10,000 dollars to fix it and replace the engine... not including tax. The worse part is sometime like a year ago I went to a dealership because I had an apt for an oil change. The day before my check engine light turned on. So at the apt while checking in my car I mentioned to the guy taking photos of my car that the check engine light was on and please check it out. I waited two hours for them to give me my keys back and say I didn't make the appointment for the check engine light so they couldn't see what was wrong with it that day. And that had never happened before. At the time I had only been to dealerships to fix my car and The dealerships always agreed to check out the engine light when it was on except for this one time. Felt like I was getting pushed out the door. So I've spent the last year going to other mechanics attempting to fix the check engine light and it always just came back on when I got my car back. Tune ups, spark plugs, cylinder misfires. Elantra GT's are not represented in any of the recall articles I read about online so I felt the need to share my story because I think my car had the same engine as some of the other cars. RIP Elantra GT

The piston rings do not seal leading to increased oil consumption and very low oil. My safety was put at risk because when I pulled out into traffic that was going at a high speed I could not accelerate. There was no warning or indication that this was going on prior to this incident. Yes this has been confirmed by a Hyundai dealership and the component was inspected. There was no warning sign before this incident.

Good Morning, This model and year of vehicle has had so many defects. I have paid hundreds of dollars over simple vehicle factors that Hyundai Manufacturers should really assess while pushing them to the market. This mode has had many brake light defect all consisting of the electrical wiring. I have changed MANY times the Brie lights bulbs only for them to blowout within a week. This is a roadway safety issue. Worse of all the ENGINE Is Faulty and the vehicles for this specific year tend to seize up or blowout due to the vehicle burning oil WAY BEFORE 3000 miles. I’ve had to change oil now every month because the engine will literally start making a screeching noise under the hood. Only to realize that the car has zero oil yet zero leaks under 1000 miles of driven. The dealership recently changed my oil and filter and after 1,500 miles I realized the engine making this noise for the 3rd time. I have now filed a complaint with their head office, to only have them dismiss me and not care for the safety of others. I am most definitely not the first person that owns this model and has been phasing with this SAFETY problem. Please help us out and investigate this matter. This is not ethical practice and we should not be worried about our safety on a manufacturing defect.

I purchased this vehicle from Duncan Hyundai in Christiansburg VA on 11/13/2021. When I purchased the vehicle it had 90,588 miles on it. I started hearing a knocking sound coming from the engine in late January - early February 2022 only 2-3 months of having the car. The engine light came on and the car was also smoking some. We checked the oil in the vehicle and it was empty. We put a quart in the vehicle to take it to the dealership. We were told that yes, the vehicle in fact did not have any oil in it. I asked them well were did the oil go? Is there a leak or something? Oil just doesn't disappear like that. The mileage on the car at that time was 93,543. It wasn't even due for an oil change. I was told that this particular vehicle burns oil and every thousand miles & we will have to add a quart to it at that time. We are now monitoring that. I see that Hyundai has an open recall for this same knocking sound and burning oil on the 2019-2020 models. My 2014 is having the same problem and now I will have to take it back and forth to the dealership to make sure they monitor and hopefully eventually fix the problem for me. Again all they said at the moment was add a quart every thousand miles. In a month period (March) I have had to add 2.5 quarts to the vehicle. The vehicle now has a total of 94,916 miles on it. In a total of 1,373 miles it burned 2.5 quarts. What the dealership said about a quart every thousand miles was not correct. It has burned double that amount.

Bought brand new, original owner warranty verified and regular maintenance done at 5k intervals instead of 7500 miles due to burning oil within first year of ownership. Dealership has refused opportunities to inspect and repair for other warrantable defects in backup camara, sunroof, etc. Car out of service since 3-28-19, at 55000 miles clutch assembly rivets detached and powertrain failed causing a cracked rod. Car was presented to dealer. Dealer refused. Hyundai assurance refused tow to next dealer without upfront payment. Car was taken to local aamco where defective rivets were diagnosed. Oem clutch was retained for evidence. Car was examined by second ase technician, car was deemed hazardous to drive and could cause fire if rod broke and punctured engine wall due to direct injection system. Costs for repair/rental/tow approached 15000, so rental was turned in and another vehicle was purchased to provide transportation while arbitrating complaint. Its only vehicle single parent and warranty covers repair/tow/rental, but hyundai corporate and dealer have yet to provide any remedy (still as of 7-17-19) per cfr rule 703 or magnusson-moss act claim with bbb autoline was filed certified mail on 5-15-19. Bbb mediator faked phone call agreement and perjured settlement letter. Offer was never accepted because neither hyundai nor bbb are following rule 703 procedures and did not complete response form. Instead bbb assigned a specialist to personally attack and interrogate attempting to coerce me. Multiple requests for arbitration have been negated or ignored. Local bbb office in town of residence was contacted end of june. The representative that said she could get arbitration setup was fired the day after. Was told by director of operations they may not have arbitrator available and will require travel 5 hrs away to attend hearing if hyundai agrees to arbitrate?

2014 elantra gt manual 6 speed, purchased 8/6/18 with 31,636 miles from a non hyundai dealer in massachusetts. I live in upstate ny. The car came with a 90 day or 3,750 mile dealer warranty, and is still under the factory warranty up to 60,000 miles. I'm the 2nd owner. At approx 34,500 miles, on 10/5/18, while accelerating uphill, the engine began to make a sharp and loud rapping and squealing noise and lost power. I was in heavy traffic on a country road with no where to stop, but I managed to pull over after coasting downhill for approximately one mile. I checked the engine oil immediately and there was no oil showing on the dipstick. I called my wife to come and pick me up and asked her to bring 3 quarts of sae 5-20 oil as indicated on the fill cap. It took 2 quarts of added oil for any oil to show on the dipstick, indicating that there had been significant and excessive oil consumption in the 2 months from my date of purchase, at which time the dipstick indicated that the oil was at the full level. The car had an oil change prior to my purchase per the salesman at the dealership where I bought the car. There were no warning lights on prior to the engine failure, and non came on afterward. The car is at a local hyundai dealer being diagnosed. The hyundai dealer provided me with a loaner car "for the duration", that they told me was included as part of the factory warranty and would be free of charge. I suspect a crankshaft bearing, con rod bearing and/or wrist pin failure, and seized piston(s) due to oil starvation.
