2017 Hyundai Elantra Owner Complaints

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.

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.

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.

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.

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 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.

I have been having this issue for several months. First, it was the steering wheel being locked. I believe at one point and time on the past they updated the computer on that vehicle. But this time the dealer told me there is nothing they can do. As of today, the car won’t start. How can I go to work? There is no Safety Recall for this, but I didn’t brake the car’s computer, I don’t even know and want to know where it is located.

After no previous issues, car stalled out multiple times on short drive to work. No warning lights and no subsequent diagnostic codes were reported. Upon final restart, engine started knocking severely. Upon investigation, the oil stick showed no oil in the pan. Vehicle was towed to trusted, licensed mechanic for evaluation where we were informed about the potential of a failure due to rapid oil consumption. The mechanic confirmed the engine failure to to oil loss. Vehicle had received regular, documented maintenance and fluids were checked periodically between cycles. There was no low-fluid indicator prior to the mechanical failure. Dealership-level conversations confirmed the rapid oil consumption issue for the 2017 Elantra is common, but because the vehicle VIN was not listed as part of a prior recall no assistance could be provided to repair the engine. The dealer provided a full cost quote of $9,000 to replace the engine block with a remanufactured unit.

With no 'low oil' warning, the car's engine started may a knocking noise. Then, all kinds of warning lights started. Parked the vehicle and checked the oil the next day and there was NO OIL in the engine. This should not have been the case considering this car gets regular oil changes. Also, there was no oil spots or stains on the driveway to also indicate an oil leak. This happened to my son while driving home from work on the interstate at 10:30 at night. That is concerning.

While driving, pressing the accelerator pedal, the vehicle hesitated and stalled. No warning lights came on until after I attempted to turn the vehicle back on then the check engine light and low oil light were illuminated. My vehicle was towed to a local mechanic and I was informed that the engine was blown and to tow my car to a Hyundai dealership as I was still under the 10 year/100k mile warranty. After getting my car to Hyundai, I was told I had to get a combustion cleaning for $800 whether the cleaning worked or not before any warranty work could be completed. The cleaning did not work and it was then found that a pin was sheared off inside the engine. My engine was then replaced under warranty but I still had to pay for the cleaning. A second mechanic looked over my paperwork after getting my car back 2 months later and noted that the engine failure could have been diagnosed without the cleaning as the cleaning would not have affected where the pin was sheared off. My 2017 Elantra had 90,315 at the time of this incident.
