2015 Hyundai Elantra Complaints

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.
