   The vehicle experienced severe, sudden loss of power while driving, leaving the car unable to exceed approximately 40 MPH on public roads and highways. This restriction creates an immediate rear-end collision hazard and severely degrades acceleration under traffic conditions. Diagnostic & Technical History: The vehicle previously triggered Diagnostic Trouble Code (DTC) P1326 (Knock Sensor / Engine Limp Mode). Diagnostic testing at Holler Hyundai under Techline Case #2026040700281 confirmed severe internal mechanical compression failure in Cylinder 4. Cylinder 4 failed dry compression testing and required a wet compression test (oil added to the cylinder) to hold pressure at 151 PSI. Severe internal engine oil pass-through/blow-by from the damaged cylinder has clogged the catalytic converter with baked oil ash, creating extreme exhaust backpressure that physically restricts vehicle speed and throttle response. Holler Hyundai recently replaced the physical knock sensor to clear the active P1326 light, but the underlying internal mechanical engine damage and clogged exhaust remain unaddressed. Corporate & Warranty Refusal: Hyundai Motor America (Executive Corporate Case #43193886) has formally denied goodwill coverage and engine replacement. Corporate is refusing to address the internal mechanical failure without requiring out-of-pocket diagnostic procedures, despite documented cylinder failure and a severe ongoing highway safety hazard.

   I am writing to formally report a serious vehicle safety concern involving a 2015 Hyundai Elantra, VIN [XXX], which is owned by my mother. The vehicle experienced a sudden loss of power steering assistance, creating an immediate and significant safety concern. This could have caused a series issue to myself and others on the road. Following the incident, I took the vehicle to a Hyundai dealership for inspection and diagnosis. The dealership advised that the vehicle’s VIN is not currently covered by a Hyundai recall for this issue. What is particularly concerning is that Hyundai has issued recalls involving power steering/electric power steering failures and related loss-of-steering-assistance concerns on various Hyundai models and model years. Given the nature of the failure and the similarities among reported power steering defects, I am concerned that this vehicle may be experiencing the same or a substantially similar safety-related defect, despite Hyundai currently stating that this particular VIN is not included in a recall. I respectfully ask NHTSA to: Review this incident and the underlying power steering failure associated with this 2015 Hyundai Elantra and determine whether the issue represents a broader safety defect. I understand that not every mechanical failure qualifies as a safety defect or recall. However, a sudden and unexpected loss of power steering assistance is fundamentally different from an ordinary wear-and-tear repair because it can affect the driver’s ability to safely control the vehicle. I am asking NHTSA to please review this matter as a potential safety defect. I would also appreciate confirmation that this complaint has been received and consideration of whether additional information, dealership documentation, diagnostic records, photographs, or repair estimates would assist with your investigation. Thank you for your attention to this matter and for your role in protecting the safety of motorists and the public. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

   Failed engine due to class action recall

4. Filed Jul 13, 2026Failure May 8, 2026Chino, CAEngine

   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.

    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.

    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.

    I had a trunk latch recall done on my car in June 2024. Immediately after that, my trunk stopped opening with the key fob. The latch would click but not release. A few weeks ago, it started doing the same thing with the release lever by the driver's side. There was no way to get the trunk open, so I went to a different Hyundai dealership than where my recall was done at (due to travel costs from school). They had to replace the trunk latch because the recall latch was installed incorrectly. It was an almost $700 expense.

    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.
