Engine failure consistent with known Hyundai engine defect. Blue smoke, oil consumption, engine knock Mechanic autoscanned codes were P0300, PO301, PO302 Lost half quart of oil in 800 miles Fire risk acknowledged in recall documentation - undriveable car at Hyundai dealer in Salem NH, renting a car now as without any transportation Manufacturer denied repair based solely on VIN despite identical failure

2015 Hyundai Elantra is consuming oil. I have changed the oil on all of my vehicles ever since I have owned vehicles and this vehicle purchased used for my children and maintained by me is consuming oil requiring addition of +/- a quart of oil between trips from Baltimore, MD to New Haven, CT. Oil lamp on dashboard is lighting indicating low level of oil upon return to home just north of Baltimore December 15, 2025 after a trip north to New Haven CT November 29, 2025. Oil was topped off prior to trip back to school on November 28, 2025 and 16 days later after trip home on December 15, 2015, oil lamp on dash is lighting and oil level is low. There are no observations of oil leaking at home or in parking garage at New Haven, CT

My 2015 Hyundai Elantra fits the 'window' of Elantras where the engine transmission slips gears without notice. Hyundai dealers have been replacing transmissions at no cost, if the car is still under 100,000 miles, as part of a class action settlement. As the second owner, I have no warranty rights to get Hyundai to fix my car at no cost. This is despite the Hyundai dealer just today (Aug 20, 2025) here in Las Vegas was ready to replace my transmission at no cost until they found out I am the second owner. The car is still unsafe. The need is still relevant. The dealer was willing at first. Now I am faced with an unsafe vehicle forced to possibly pass in excess of $4,000 to fix an issue that has been know and litigated.

Hello my vehicle developed a knock and it has become so much worse, I will not drive it. Hyundai has played games with me. My vehicle has been at Jenkins Subaru three times at Hyundai request. This third time my vehicle had to be towed to Jenkins Subaru. Now Hyundai tells me they will not repair my vehicle even though they have been aware with this lifter knock piston slap issue for quite some time now. I need help. I am [XXX] [XXX] and rely on this vehicle to get me to doctors appointments and general errands. I really don't know what to do. I am afraid to drive the vehicle because of fire issues and possibly staling out on the interstate and me getting hit by another vehicle. Please help. My vehicle now sits at Jenkins Subaru in Clarksburg wv and I have no way to bring it back to Fairmont wv. A 20 to 25 minutes trip could be deadly to to bring it home. Hyundai could have cared less that I had to had the vehicle towed to Jenkins Subaru, there reasoning is it has 104,000 miles on it. I told Hyundai they must make throw away vehicles then.

Vehicle routinely (3,000-5,000 miles, depending on oil used) maintained by qualified mechanics. Around 129,000 miles the engine began to knock / rattle. Mechanic was unable to determine the cause, but the rattle was only present between 0-40mph and would settle at higher speeds. Mechanic also noted the absence of sludge. Around 133,000 miles the vehicle stalled. The vehicle would start, but would stall again. Mechanic diagnosed timing chain failure and that the vehicle is burning oil. Vehicle has never indicated low oil, but it is now manually checked and burning about a quart of oil per 1,000 miles. Replaced timing chain and vehicle has continued to operate. Around 134,500 miles some power loss during low-speed acceleration and a slight engine rumble at lower speed. Mechanic diagnosed a wrist pin failure on cylinder 2. Vehicle may be inspected upon request. Vehicle stalls create some safety concerns, but have only occurred at low speeds. Vehicle timing chain was diagnosed by two different mechanics. When the vehicle was brought to a Hyundai dealership for a trunk latch recall in May of 2024 at 125,000 miles, no issues were noted. Vehicle has not been inspected by the manufacturer, police, or insurance represenstatives since May of 2024, with no reported issues. No check engine notifications or warnings appeared until the vehicle stalled. Prior to slightly decreased acceleration, the only notable indicator of an issue is the persistent engine rattle (knock, piston slap). The engine rattle began in February of 2025.

Check engine light came on, the code says misfire on random cylinders, drives very rough. Took to mechanic and said timing chain is loose, which causes the “skipping” or misfire, and could snap at any moment (which is unsafe and could cause a wreck). Mechanic has 3 other Hyundai Elantra's with same problem. Around 2 grand fix.

While operating my 2015 Hyundai ELANTRA, the engine cuts out.. it just stalls out of nowhere without any signs or warnings its about to happen. As well as approximately 50% of the time the engine stalls the power steering also stops working. At this point I have to coast to the side of the road, put it in park, turn the key to the off position and then restart the car when this happens which is quite often. The worst its ever been was 8 times in a 25 minute/28 mile drive. This doesn’t only happen at fast or slow speeds. It’s completely random whether I’m going 15 mph in a school zone 25 to 40 mph through towns or 65 to 70 mph on highways. This is already extremely dangerous to happen. Going 15 to 40 mph but when you’re driving on a highway at 65 or 70 mph and the engine and power steering just stop and cut out, this is severely dangerous. I’ve been in contact with the Hyundai headquarters multiple times and they are not doing a single thing about it so my car has just been sitting for about 5 months now. Please help me hold Hyundai financially responsible for safety recall repairs. This manufacturer safety issue is unacceptable and my car has been very well maintained and has very low miles under 70k miles on a 2015

Was driving 2/6/24 and oil light came on. Engine smelled bad then entire car stopped working, e.g. brake pedal locked and the dashboard lit up. Ran over a median to manually stop the car. Had car towed to Hyundai dealership, who stated that an oil change from Firestone in 12/2023 was the culprit. Upon inspection the oil filter had a bulging gasket which was presumed to allow the car to slowly leak oil, leading to impending catastrophic engine failure. I appealed to Firestone and they completed an inspection and provided a report that showed the Hyundai engine itself was faulty and warped the oil filter based on detailed caliper measurements. In light of the Hyundai/Kia engine troubles, I wanted to submit a report in case my year and make and model make a recall list for engine issues.

When I come to a stop the car randomly shuts off and the engine lights come on. I have to put it in neutral and restart the car. This is happening all the time and scares me. I'm afraid that one day I will have to stop on the interstate and my car dies when traffic resumes putting me in danger.

When I come to a stop the car randomly shuts off. All the warning lights come on. I have to put it in neutral and it usually starts right back up. It's happening a lot more often now.

The car engine seized on me. Went to work in the am and by the afternoon the car was non drivable. Had it tolled to a Hyundai dealership and couple of other car repair shops and they all confirmed that the engine has died. I haven't even had the car for a year. There was no indicators on the screen or any kind of warning such as an engine light. Good thing the car was in park when before it seized, otherwise I could have been driving it and could have happened on the road.

Multiple times now, the vehicle has stalled while I am driving and turned off. Both my battery and alternator are still good, however this continues to happen. This happens at any speed, but most commonly at low speeds, while slowing down. This typically starts with the engine chugging or the car begins lurching instead of moving fluidly. As this is happening the light cluster will also flash and then go off or will illuminate the oil pressure warning light. I have had the oil level checked and can confirm this is also not an issue. The only way to get the car back on is to put the vehicle in park, and turn it over until it starts. It will normally start on the first try but at times it has taken several attempts. Additionally the car now produces a strong exhaust smell anytime I am driving it even though it has not done so before and there are no issues with my exhaust system currently. The vehicle currently has around 180,000 miles but from what I have read on this site there are many individuals experiencing this same issue with varying mileage. This is obviously a major concern as I have kept the vehicle maintained normally and this seems to have come out of nowhere and this is a significant safety hazard both for myself and others. As many have stated already in their complaints their vehicle has also experienced this exact issue while driving putting themselves and others in danger. The only fix I have seen on the site here is to replace the engine which is absurd given that this seems to be a manufacturer issue and not on the vehicle owner from what I can tell based on the number of related complaints that are the exact same issue.
