2017 HYUNDAI ELANTRA Complaints

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.

My vehicle was brought to an authorized Hyundai dealership In November 2025 to complete safety recall campaign KSDS (Campaign 966). Soon after picking up the vehicle after the dealer flashed the ECU, the vehicle went into a permanent, dangerous "limp mode" that severely limits the engine's RPMs, making it impossible to accelerate to highway speeds. The vehicle's computer displays zero OBD-II diagnostic trouble codes (no P1326 or standard fault codes). The dealership is refusing to address this issue, falsely claiming a plugged catalytic converter, despite the vehicle having passed a strict California Smog Check with perfect emissions and zero catalyst codes, just a few weeks before the update was performed, and ran perfectly normal. This recall software update has rendered my vehicle extremely unsafe to drive on public roads, and the manufacturer's authorized repair facility is refusing to remedy the electronic damage caused by the recall installation. I am trapped driving a disabled vehicle in a permanent, dangerous software loop.

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.

I am writing to formally log a critical safety and product reliability complaint regarding my Hyundai Elantra GT. The vehicle has suffered catastrophic engine failure characterized by severe rod knock. This failure occurred without any prior warning from the vehicle’s onboard diagnostic systems, exposing an engineering and sensor flaw that creates an immediate safety hazard.The vehicle was operating normally when it suddenly developed a distinct, heavy metallic knocking sound from the engine block, indicative of failed connecting rod bearings. Upon immediate inspection, the issue was linked to critical oil starvation or pressure drops.Crucially, the vehicle’s warning systems failed entirely to alert me to an issue:No Low Oil Pressure Warning: The dashboard oil pressure light never illuminated to warn of low pressure or critical oil level depletion.No Check Engine Light (CEL): The engine sensors failed to detect underlying mechanical distress, oil degradation, or early-stage misfires before the catastrophic failure occurred.Complete System Silence: The vehicle gave absolutely no visual or audible alerts on the instrument cluster, depriving me of the chance to pull over safely and shut off the engine to prevent total destruction.This sensor failure is an unacceptable safety risk. Total engine seizure at highway speeds can cause a sudden loss of motive power, power steering, and braking assist, endangering my life and the lives of others on the road. The failure of Hyundai’s diagnostic sensors to communicate active oil or mechanical breakdown directly directly caused this total engine loss.I request that Hyundai review this case immediately, investigate the failure of the warning systems, and provide financial remediation for the required engine replacement.I look forward to your prompt response regarding the next steps for a corporate review.

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.

After a Hyundai dealership installed the Knock Sensor Detection System (KSDS) update to prevent engine bearing failure and potential fires in certain Theta II, Nu, and Gamma engines, my Elantra GT is stuck in limp mode and will no longer accelerate. Since it takes my car a very long time to reach safe driving speeds, I took the car back to the dealership and they conveniently blamed the catalytic converter. I went for a ride with a California BAR associate, and he agreed that the update was causing my engine to go into limp mode, and it wasn't a symptom of a plugged CAT, but he was unable or unwilling to help me. Hyundai acknowledged that the engine does qualify for the Theta II extended warranty but will not explore that possibility until I have them replace the cat for $3,300, which we both know isn't going to solve anything. I have contacted Hyundai Corporate Customer Relations, and even the BBB, who refuses to qualify my car for their Engine Replacement class action lawsuit because the engine hasn't seized up yet, which will never happen since the update is preventing it. Even lemon law lawyers refuse to assist me because the car is too old. Since this is the only car I have, I am a nervous reck whenever I have to use it. If I press the accelerator pedal just a bit too much, the engine cuts out.

I am filing a formal complaint regarding my 2017 Hyundai Elantra SE (VIN: [XXX] ). The vehicle is currently experiencing severe safety issues, including unexpected engine stalling and loud mechanical rattling, alongside a P0014 diagnostic code. These symptoms align directly with the defects described in Recall 203 (NHTSA 21V301000) involving improper piston ring heat treatment and Service Campaign 966regarding engine bearing wear. As a consumer, I am extremely concerned about the risk of a crash due to sudden loss of power. I am really concerned for my son and I as I drive my vehicle. I am requesting: 1. An immediate inspection and confirmation of eligibility for an engine replacement at no cost to me. 2. Verification of the lifetime long-block warranty extension associated with the KSDS (Campaign 966) update. 3. Provision of a loaner vehicle or rental reimbursement while my primary vehicle is unsafe to operate. Please assign a case manager to this matter and provide a timeline for resolution.
