ENGINE
Vehicle Information: Year/Make/Model: 2017 Hyundai Elantra Value Edition Mileage: ~135,000 miles Engine: 2.0L Nu 4-Cylinder VIN: [XXX] Incidence Summary: Engine internal failure, metallic debris/shavings found in oil, severe knocking noise, high risk of sudden engine stall/failure while driving. Detailed Description of the Incident: While driving home, the vehicle began producing a loud, severe metallic knocking noise from the engine compartment. The engine continued running, but the noise persisted throughout the trip. Upon inspecting the vehicle, a certified mechanic removed the engine oil and discovered a significant amount of metallic debris and metal shavings inside the oil pan, indicating severe internal engine component wear (connecting rod bearing / crankshaft failure). The mechanic advised that the engine is at immediate risk of seizing or experiencing complete catastrophic failure. Safety Risk: A sudden engine failure or seizure while driving on a highway or at high speeds creates a critical safety hazard, as it can cause an immediate loss of power, loss of power steering/braking assistance, and significantly increase the risk of a crash or rear-end collision for me and surrounding traffic. Current Status: The vehicle is no longer safe to drive and has been grounded to prevent complete engine lockup or serious road accidents.

SERVICE BRAKES
My 2017 Hyundai Elantra SE 2.0L (outside Recall 157/17V063 VIN range) has suffered 7 intermittent brake failures since 06/03/2026 (~118,563 mi), involving total loss of braking power, a rock-hard pedal, and/or resistance during pedal depression. The vehicle is at Temecula Hyundai and available for inspection. SAFETY RISK: Across 7 incidents (06/03, 06/17, 06/23, 08/29, 09/19, 10/09, 10/11), the brake pedal either met strong resistance halfway down with rapid metallic ticking from the front-left/under-hood area and reduced stopping power, or became completely rock-hard with total loss of braking power for 5-10 seconds (frequently while braking downhill). On 09/19, 1-2 seconds of pedal resistance/ticking transitioned directly into a rock-hard pedal and total brake loss. On 06/03, I had to jump a curb to avoid traffic. On 06/23, 09/19, and 10/11, I had to use the emergency brake to stop. On 10/11, total brake loss approaching a stoplight forced a hard e-brake pull, locking the rear tires and spinning the car sideways in front of cross-traffic before brakes returned 8-10 seconds later. REPRODUCTION & INSPECTIONS: Inspected by Temecula Hyundai across 5 visits (96+ cumulative days in shop) and an independent shop (both verified brake pads, rotors, and calipers are good). In June 2026, a dealer technician reproduced the stiff brake pedal on a road test and replaced the brake booster under warranty (06/16), without documenting on the work order if vacuum check valve/hose or ABS HECU causes were ruled out as the root cause. Failures recurred within the same week. On 10/13, a dealer advisor confirmed a front-left growling/chirping noise on a road test, yet the dealer only suggested customer-pay brake pads (with "high confidence" it would fix the total/complete brake failures). WARNING LAMPS: Zero warning lights or codes have ever appeared before, during, or after any incident. A near-daily front-left growling and chirping noise is present (not constant during all braking).

ENGINE, VEHICLE SPEED CONTROL
I leased my 2017 Hyundai Elantra new in July 2016 and later purchased it. As of September 2026, it has approximately 77,000 miles. I am reporting two unresolved safety concerns despite repeated repairs and more than five months of seeking assistance from Hyundai. Multiple ignition coils have failed during my ownership. Most recently, I paid approximately $400 for service after another coil failure. Although the check engine light is no longer illuminated, the vehicle continues to struggle to accelerate and abruptly jerks or “burps,” particularly around 30 mph. At times, I must press the accelerator nearly to the floor to gain enough speed to safely merge onto the highway. I commute approximately 40 miles round trip, including stop-and-go highway traffic, and am concerned about my safety. When I reported that the symptoms continued after the repair, the Hyundai dealer said I would need to pay another diagnostic fee while also stating their equipment might not identify the problem without an illuminated check engine light. My driver-side exterior door handle is also completely inoperable. This issue was previously repaired by Hyundai under warranty and a known issue with the model year, but the repair has failed and the driver’s door cannot be opened from outside. To enter my vehicle, I must climb through the front passenger door, lower the driver’s window, exit, walk around the vehicle, reach through the window, and open the door using the interior handle. After more than five months of contacting Hyundai and seeking service, both issues remain unresolved. I am concerned about the safety of continuing to operate this vehicle and about the failure of a previously completed recall repair. I am requesting that NHTSA document and review these safety concerns.

ENGINE
I bought my 2017 Hyundai Elantra SE earlier this year with about 119,000 miles. It had good maintenance records when I bought it, and it now has about 128,000 miles. Since buying it, I've had two oil changes done along with new spark plugs, coils, front brake pads, and tires. About two days before the engine failed, I noticed the car had suddenly burned through a significant amount of oil. There was no visible oil leak. The car stopped running, so I had it towed instead of continuing to drive it. Oil was added, and afterward it started and seemed to be running fine.The next day, I was driving approximately 70 mph on the interstate when the car suddenly lost acceleration and warning lights came on. There was smoke while I was driving, including smoke/fumes coming into the car. Afterward, there was oil everywhere. The car had to be towed again and is no longer drivable.What concerns me most is how quickly this happened. The car went from suddenly consuming oil with no visible leak to losing acceleration and experiencing a major engine failure while I was traveling 70 mph on the interstate. Losing power at that speed was dangerous, and the amount of oil and smoke also made me concerned about the possibility of a fire. Hyundai has told me the vehicle is no longer under warranty. I have not paid for an extensive engine teardown yet. My grandfather looked and he said it appears the engine threw a connecting rod through the side of the engine block. With the valve cover off, the engine looked brand new. I'm filing this complaint because an engine suddenly losing power at interstate speeds, along with oil and smoke, is a serious safety concern, especially with the potential for a fire. I hope NHTSA will compare this incident with other complaints involving engine failure and excessive oil consumption in 2017 Hyundai Elantras. Currently, it's available for inspection.

All four rear/side door latch mechanisms have exhibited intermittent failure to release the door from the interior and/or exterior handle. Repeated operation or increased force can sometimes cause the door to release. This creates a potential safety hazard because an occupant may be unable to exit the vehicle through an affected door during an emergency. The manufacturer has previously issued an extended warranty/TSB addressing this latch failure, but the vehicle is now beyond the 10-year extension period.

The contact owns a 2017 Hyundai Elantra. The contact stated that while driving 50 MPH, there was an abnormal knocking sound coming from the engine. The contact pulled over to the right side of the road, turned off and restarted the vehicle, and the vehicle operated as intended. No warning light was illuminated. An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The engine was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure and referred the contact to the BBB to report the issue. The approximate failure mileage was 108,404.

Vehicle stalled while driving on a highway without warning. The car was able to start back up, would go a few feet and stall again. Had it towed to a Hyundai dealership to repair. They replaced the exhaust camshaft and timing components. They released the car, saying it was fixed. Less than 12 hours later, the car stalled again while driving through Washington DC. Once again, it would start up again but stall every few feet. We took it to another Hyundai dealership. They replaced the oil pump (saying the oil pressure was too high). That did not fix the issue and the dealership stated that the intake camshaft needed to be repaired. The third party warranty company would not approve that repair, as they are saying the engine needs to be completely replaced. We bought the car in March. The first incident occurred in June and the second incident was 12 hours later. The car has been at the dealership for 'repairs' ever since.

ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
While operating my 2017 Hyundai Elantra under normal driving conditions at approximately 70,000 miles, the engine suffered a sudden, catastrophic loss of motive power and stalled completely while moving in active traffic without any prior warning. This severe stalling event occurred despite the vehicle being strictly and meticulously maintained according to all manufacturer guidelines and scheduled service intervals. Prior to the stall, the Check Engine Light illuminated. A comprehensive diagnostic scan completed at an authorized Hyundai dealership confirmed active trouble codes P0014 (Exhaust Camshaft Position Timing Over-Advanced) and P0017 (Crankshaft-Camshaft Position Correlation Error). The internal physical engine timing assembly and Variable Valve Timing (VVT) components slipped out of synchronization, forcing an abrupt, automatic engine shutdown while navigating active roadways. This failure created an immediate, severe safety hazard and high collision risk due to the sudden loss of vehicle propulsion, power steering assist, and vacuum brake booster pressure, leaving me vulnerable in traffic. This structural timing deviation caused chronic engine misfires and forced raw, unburned fuel directly into the exhaust stream. This unburned fuel completely fouled and destroyed the primary Oxygen (O2) Sensor due to heavy carbon contamination and extreme thermal stress. The failed sensor and incorrect valve timing totally disrupted the electronic control unit's air-fuel management, inducing the unpredictable stalling hazard and causing an immediate, automatic state emissions/smog inspection failure. Repairing this underlying manufacturing and metallurgical defect at the official Hyundai dealership required an extensive mechanical teardown and replacement of the timing components, costing approximately $2,500 out of pocket. This exact failure pattern, cascading O2 sensor damage, and diagnostic trouble codes match hundreds of existing complaints with NHTSA.

STEERING
While driving and turning, the car loses power steering. This has happened multiple times to my wife at lower driving speeds. These disconcerting safety incidents have randomly occurred without warning since the first week of May. The incident was first reported and taken to the Hyundai dealership on May 6th. The dealer looked at the car and stated no issues with steering. It has occurred multiple times since then. The last incident occurred on June 9th at 4pm at Phoenix Sky Harbor Airport. The car lost power steering control, a warning light briefly flashed and the engine shut off. I recovered the car and restarted it. The power steering reset itself. The car was taken a few days later to a Hyundai Dealer who has had the car since attempting to diagnose the issue. The dealer is now stating we should just replace the entire steering column assembly.

UNKNOWN OR OTHER
I am reporting an active odometer fraud case on a 2017 Hyundai Elantra, VIN: [XXX]. The seller listed this vehicle on Facebook Marketplace claiming it had 65,000 miles and was in like-new condition. Upon running a CARFAX report, the vehicle shows over 300,000 actual miles. The CARFAX also shows the vehicle already had 98,000 miles recorded in 2018, making the current 65,000-mile claim impossible. When I confronted the seller about the discrepancy, they claimed they purchased the vehicle from a mechanic and were unaware of the mileage history. They then immediately blocked me and deleted their Facebook listing. Shortly after, a second listing appeared under what appears to be the seller's wife's account advertising the same vehicle. The vehicle appears to have originated from Illinois and is being sold in Indiana, making this a cross-state fraud. The seller operates as a title-free flipper, never placing the title in their name, which appears to be an intentional strategy to avoid a paper trail. I have documentation including screenshots of the original listing, the CARFAX report, and records of my communications with the seller. I am prepared to provide all of this upon request.

1. The engine architecture suffered a catastrophic mechanical failure. Specifically, severe, systemic internal oil consumption/vaporization starved the hydraulic timing chain tensioner of critical hydrostatic pressure. This caused the tensioner to collapse, creating slack in the steel timing chain, which then "jumped time" (skipped a tooth on the camshaft sprockets), causing the engine to instantly seize and lose all motive power. The vehicle and engine are fully intact and available for inspection at Pohanka Hyundai of Fredericksburg. 2. The vehicle suffered a sudden, complete loss of motive power and engine seizure while being driven at night on an unlit, dark secondary roadway. The driver (my daughter) was left suddenly stranded without power in a highly vulnerable, pitch-black location with passing traffic, presenting an immediate collision hazard and a severe personal safety risk before emergency assistance could arrive. 3. Yes. The vehicle was towed to an authorized Hyundai dealership (Pohanka Hyundai of Fredericksburg), where service technicians officially diagnosed that the engine had "jumped timing" and suffered a complete failure of the timing system, alongside a noted lack of engine oil volume due to vaporization. 4. The vehicle has been formally inspected and diagnosed by the authorized Hyundai dealership service department under Hyundai Motor America Corporate Case #[XXX]. No police or insurance inspections were required as no collision occurred. 5. No dash lights or warnings before failure. However, for a year prior, the engine exhibited severe internal oil vaporization, requiring constant top-offs between scheduled oil changes to maintain safe levels. There were zero external fluid leaks on the engine or ground; oil burned entirely internally. This chronic volumetric oil loss directly caused the sudden drop in pressure, hydraulic tensioner collapse, and catastrophic engine seizure.

Both passenger-side doors won't open without tugging on the handle when unlocking them. The front seat passenger door opens from the inside but has trouble opening from the outside. The backseat passenger does not open from the inside at all and has a hard time opening from the outside. Once we get the door open and the car remains unlocked, the doors open fine (except for the back seat door). But once we lock and unlock the car, we get the same issue. I'm also experiencing paint chippng and rust on the roof of my car and the creases of the trunk.

What component or system failed or malfunctioned, and is it available for inspection upon request? How was your safety or the safety of others put at risk? The ignition coil in my 2017 Hyundai Elantra Limited has failed multiple times over the past several years. This recurring issue has caused the vehicle to malfunction unexpectedly, creating safety concerns due to reduced engine performance, misfiring, and the potential for sudden loss of power while driving, which puts both myself and others on the road at risk. The failed component is available for inspection upon request. Has the problem been reproduced or confirmed by a dealer or independent service center? This issue has occurred multiple times with my vehicle. After researching online consumer reports and owner complaints, I found that ignition coil failures appear to be a common and recurring issue reported by other 2017 Hyundai Elantra Limited owners. Based on these repeated failures and similar reports, this appears to be a known issue affecting this model. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? I have reported this issue to Hyundai multiple times. Rather than addressing the root cause or issuing a recall for this recurring defect, Hyundai has repeatedly provided credits to assist with repair costs when the ignition coil fails. Despite the repeated failures and safety concerns, the underlying issue has not been permanently resolved. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Prior to failure, the vehicle would experience rough starts, engine misfires, and poor performance. After these symptoms began, the check engine light would eventually illuminate. Once the warning light appeared, the vehicle became increasingly unreliable and would stall or shut off unexpectedly. On one occasion, the vehicle shut off completely while I was driving.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving. This most often occurs when I am decelerating and turning, such as when entering or navigating roundabouts. At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the failure occurs—no unusual noises, no loss of power leading up to the event, and no dashboard warnings in advance. The stall is sudden and unexpected. When the vehicle stalls, I must quickly shift into park and restart the engine. The car restarts immediately without hesitation, and all warning lights disappear. The vehicle then operates normally again until the issue randomly reoccurs. This has happened multiple times. This issue creates a safety risk because the vehicle loses power unexpectedly while in motion, particularly during low-speed turns and in roundabouts, which could increase the risk of a collision due to sudden loss of propulsion and reduced control. The problem has not yet been formally diagnosed by a dealer or independent repair shop, but based on research and similar reported cases, it may be related to an intermittent engine or electrical signal failure. The issue has not yet been inspected by the manufacturer, police, or insurance representatives. UNKNOWN as to the exact failed component, but the failure appears to involve a sudden loss of engine operation without warning, followed by immediate recovery upon restart.

Component or system failed: The electrical and/or engine system failed spontaneously. Gray smoke originated from under the hood, followed by black smoke and an intense fire. The vehicle is NOT available for inspection as it was declared a total loss and scrapped 30 days after the incident. Safety risk: My safety was at immediate risk as I was inside the vehicle when the fire began. Public safety was also threatened; the Bloomingdale Fire Department had to evacuate a Wendy’s restaurant and its customers for two hours due to the intensity of the fire and smoke. Confirmation of problem: The problem was confirmed as a Total Loss due to fire by the Bloomingdale Fire and Police Departments on the scene. Inspections: The vehicle was inspected at the scene by police and fire officials. No manufacturer or dealer inspection was possible because the fire occurred only 7 days after purchase and the vehicle was destroyed. Warning symptoms: There were no warning lamps, messages, or symptoms prior to the failure. The smoke appeared suddenly while the vehicle was parked and idling.
