2015 Hyundai Elantra Engine Problems

Failed engine due to class action recall

Incident

Jun 17, 2026

I purchased the vehicle from a private party on 8/18/21 with 38,310 miles. Almost immediately after owning the vehicle I noticed the engine oil level was low.. The owner had said she had just got an oil change so I thought maybe the shop just left it low. Then I noticed it low again a month later, and that was the start of my nearly 5 year journey of having the carrying quarts of oil in the trunk of my car because the engine was burning the oil so quickly. Finally on 5/08/26 the car begins to run very poorly, long story short my personal mechanic and Hyundai of Ontario both confirm the engine is bad and needs to be replaced. I understand there is a history of this year of Hyundai engines burning excessive oil. The car currently has 92,362 miles and even though it’s under the 100,000 warranty Hyundai says the warranty is only offered to the original owner. Any help you can provide to determine if Hyundai has any liability related to this issue would be much appreciated.

The engine failed on a 2015 Hyundai Elantra with approximately 71,000 miles. The vehicle has an open, unresolved safety recall (Recall 251, NHTSA #23V651000) for an ABS module brake fluid leak that Hyundai has acknowledged but has not provided a remedy for. The vehicle is currently at an independent repair facility and is available for inspection upon request. The vehicle repeatedly shut off without warning while in motion and restarted mid-drive, causing sudden loss of power steering and power brakes while driving. This occurred on multiple occasions and was documented by an independent service center in February 2026. This presents a serious risk of accident, injury, or death to the driver and others on the road. The check engine light was illuminated. The vehicle experienced recurring brake issues requiring multiple repairs over several years, including brake replacement before 2026 and rear rotor, brake pad, and brake line repairs in February 2026. These brake symptoms are consistent with the known ABS module defect covered under open Recall 251. The engine shutoff symptom was first documented in February 2026 and continued until engine failure in May 2026.

I am submitting a vehicle safety complaint regarding a vehicle purchased on March 5, 2026. Within days of purchase, the vehicle exhibited multiple safety-related issues despite reportedly passing a Virginia safety inspection on February 27, 2026. The safety concerns identified include: - Driver-side headlight partially inoperable, which resulted in a traffic stop on March 15, 2026 - Front hood not properly secured/latching, creating a risk of opening while driving - No engine oil present upon inspection shortly after purchase - Coolant reservoir completely empty - Check engine light illuminated shortly after purchase Diagnostic testing following the check engine light revealed code P0420 (Catalyst System Efficiency Below Threshold). A mechanic advised that this condition is not a new issue and would have developed over time, indicating that it likely existed prior to the sale of the vehicle. At the time of purchase, the vehicle had an outstanding manufacturer safety recall identified as NHTSA Recall No. 23V651000 (Recall #251), dated April 3, 2024. This recall had not been completed prior to sale and was only addressed on March 24, 2026, after I took the vehicle to a Hyundai dealership. Additionally, the vehicle was subject to a manufacturer campaign identified as Campaign #P33, dated December 15, 2025. This further indicates that the vehicle required manufacturer-related service that had not been fully addressed prior to sale. An independent inspection conducted on March 16, 2026 confirmed conditions inconsistent with a vehicle that had recently passed a safety inspection. These issues raise serious concerns about the safety, inspection integrity, and roadworthiness of the vehicle at the time it was sold. I am requesting that this matter be reviewed for potential safety-related concerns and any related violations. I am available to provide supporting documentation, including inspection reports, diagnostic results, service records, and photographic evidence.

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.

Incident

Aug 20, 2025

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.

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.

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

Due to CDK Global cyberattack, I cannot complete my safety recall of my Hyundai Elantra 2015 (ABS Fuse that can cause engine to explode, according to Hyundai safety recall report). Hyundai does not allow dealerships to keep safety recall parts on hand (or a very small amount). I have to walk into the dealership to order the part. I cannot call to order the part. I have to constantly drive to place of work, home, sit in traffic, with a defective fuse that HyundaiUSA refuses to keep safety recall parts on hand. Please create a NATIONAL policy against manufacturers to have a minimum units (1000 units of fuses, parts, etc) as the safety recall occurs. Because dealerships cannot order parts due to this cyberattack. My mental anguish of driving a vehicle that cannot have a safety recall repaired due to parts not being able to order (especially if they can keep large amounts of units on hand at dealers), is through the roof! I cannot take time off, I have to drive to not be evicted, anything repossessed, etc. and where I live has limited transportation options, (and told to use ride share like Lyft or Uber). Insurance companies is unhelpful. If manufacturers say they cannot keep parts on hand, then how do they ship the parts so quickly, under normal operations? 3rd party mechanic shops cannot order these parts as the manufacturer has to complete the recall repair.

Within three months of purchasing this vehicle, I started having engine light and oil consumption issues. Within the 4 years of owning, they've replaced the catalytic converter twice, many valves, and others. I had to purchase and add multiple quarts of oil to just maintain oil levels. I've had multiple occasions where my vehicle slowed to only up to 55 miles an hour while on the interstate. The vehicle had issues accelerating where an accident almost occurred because pulling into a shopping plaza, the vehicle couldn't drive up a minor hill and almost remained in the intersection. I've had multiple times where I was stuck on the side of the road in different environments, a few of which I was genuinely worried for my safety. This last incident I did not feel safe to drive where I needed to go so I got off the interstate to travel down a local road where the vehicle stalled in the middle of a 5 lane (one direction) busy road. The vehicle has been inspected by the dealership and warranty representatives. The engine and oil lights were the main issues, every time a light came on I reached out to the dealership to get it looked at. I received notice of many engines being recalled and repaired in 2022 yet Hyundai has only put bandaids on my engine.

Reporting my previous VIN in case it helps the new vehicle owner since I am sure they are facing similar defects that I am with my "brand new 2016 Hyundai Elantra". I previously owned a brand new 2015 Hyundai Elantra and had to file a claim after flooding occurred in Kyle, Texas. The 2015 Elantra title was transferred to USAA after filing a claim for TOTAL LOSS due to engine flooding on [XXX]. Odometer reading on date of total loss is 7,673 miles. Vehicle appears to be sold again with same odometer reading January 2016. Both of my Hyundai Elantra's were purchased at Ron Carter Hyundai Dealership in Texas (Dealer number P113588). This dealership is now called Big Star Hyundai after DCG Acquisitions represented the sale in 2021 - just in time to deny and delay warranty covered defects to consumers who thought they purchased a brand new car. Hope this helps the current vehicle owner in case they are also over spending on dealership recommended "repairs" for their LEMON.

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.

This is a complaint for recall remedy. This recall has no remedy and they ask I park my car outside of my garage in the dead of winter. I live 4 hours from the nearest in-state dealer that could potentially provide a loaner vehicle. I’m not comfortable driving a car that I have been told can catch fire while parked OR driving on a 4 hour drive. I’ve called Hyundai multiple times with no reprieve.
