The 2017 Hyundai Elantra, while generally considered a reliable compact car, isn't without its quirks and potential issues. Understanding these common problems can help you make informed decisions about maintenance, repairs, and even whether to purchase a used 2017 Elantra. Let's dive into the most frequently reported issues and how to tackle them.

Engine Troubles: What's That Noise?

Engine problems are never fun, and unfortunately, the 2017 Elantra has seen its share. While not all owners experience these issues, it's good to be aware of the potential pitfalls.

  • Engine Knocking or Ticking: This is perhaps the most concerning issue. Owners have reported a knocking or ticking sound emanating from the engine, particularly at lower RPMs. In some cases, this can indicate serious internal engine damage, potentially requiring expensive repairs or even engine replacement. The issue may be related to connecting rod bearing wear, oil starvation, or piston issues.
    • What to do: If you hear knocking or ticking, immediately have your car inspected by a qualified mechanic. Don't delay, as continuing to drive with this issue could lead to catastrophic engine failure.
  • Engine Stalling: Some drivers have reported their 2017 Elantra stalling unexpectedly, especially at low speeds or when idling. This can be a safety hazard, particularly in traffic. Potential causes include a faulty fuel pump, a dirty throttle body, or a malfunctioning mass airflow sensor.
    • What to do: A diagnostic scan can often pinpoint the cause of the stalling. Start with the simpler possibilities like cleaning the throttle body. If the problem persists, a mechanic can further investigate the fuel system and sensors.
  • Oil Consumption: Excessive oil consumption has been reported by some 2017 Elantra owners. This means the engine is burning more oil than normal, requiring more frequent oil changes or top-offs. This can be due to worn piston rings, valve seals, or even a faulty PCV valve.
    • What to do: Monitor your oil level regularly. If you find you're adding oil frequently, have your engine inspected for leaks and internal wear. A compression test can help determine the condition of the piston rings.
  • Check Engine Light (CEL): While a CEL can illuminate for a multitude of reasons, some common culprits in the 2017 Elantra include issues with the catalytic converter, oxygen sensors, and evaporative emission control system (EVAP).
    • What to do: A diagnostic scan is essential to read the trouble codes stored in the car's computer. This will help you pinpoint the source of the problem and take appropriate action. Don't ignore the CEL, as it could indicate a problem that could worsen over time.

Transmission Troubles: Shifting Problems?

A smooth-shifting transmission is crucial for a pleasant driving experience. Unfortunately, some 2017 Elantra owners have experienced transmission-related issues.

  • Harsh Shifting: Some drivers have reported experiencing harsh or jerky shifting, particularly when the transmission is cold. This can be caused by low transmission fluid, a faulty shift solenoid, or internal transmission damage.
    • What to do: Check the transmission fluid level and condition. If the fluid is low or dirty, a fluid change may resolve the issue. If the problem persists, a mechanic can diagnose the transmission further.
  • Hesitation or Slipping: Hesitation during acceleration or the feeling that the transmission is "slipping" can indicate serious transmission problems. This could be due to worn clutch packs, a faulty torque converter, or low transmission fluid pressure.
    • What to do: This requires immediate attention from a qualified transmission specialist. Continuing to drive with a slipping transmission can cause further damage.
  • Transmission Failure: While less common, some 2017 Elantra owners have reported complete transmission failure, requiring replacement. This can be a costly repair.
    • What to do: If your transmission fails, seek professional diagnosis and repair options. Explore both rebuilt and new transmission options to determine the most cost-effective solution.
  • Delayed Engagement: Experiencing a delay when shifting from Park to Drive or Reverse can signal a problem with the transmission's internal components or fluid pressure.
    • What to do: Start by checking the transmission fluid level and condition. If that doesn't resolve the issue, a diagnostic scan and inspection by a transmission specialist are recommended.

Electrical Gremlins: Lights Flickering?

Electrical problems can be frustrating and difficult to diagnose. The 2017 Elantra has seen a few electrical issues reported.

  • Battery Drain: Some owners have reported their batteries draining unexpectedly, even overnight. This could be due to a parasitic draw, meaning something is draining power from the battery even when the car is off. Common culprits include a faulty alternator, a malfunctioning sensor, or a short circuit in the wiring.
    • What to do: A mechanic can perform a parasitic draw test to identify the source of the drain. They can then repair or replace the faulty component.
  • Infotainment System Issues: The infotainment system can sometimes freeze, glitch, or fail to respond. This can be due to software glitches or hardware failures.
    • What to do: Try restarting the system by holding the power button. If that doesn't work, a software update may be available. If the problem persists, the infotainment system may need to be replaced.
  • Power Window Problems: Some owners have experienced issues with their power windows, such as the windows not rolling up or down properly. This can be caused by a faulty window motor, a broken window regulator, or a problem with the wiring.
    • What to do: Check the window switch and the wiring harness for any obvious damage. If the switch is working properly, the window motor or regulator may need to be replaced.
  • Sensor Malfunctions: Various sensors, such as oxygen sensors, mass airflow sensors, and crankshaft position sensors, can fail and cause driveability issues or trigger the check engine light.
    • What to do: A diagnostic scan will identify the faulty sensor. Replacing the sensor is usually a straightforward repair.

Interior Annoyances: Rattles and Squeaks?

While not mechanically critical, interior issues can be annoying and detract from the overall driving experience.

  • Dashboard Rattles: Rattles in the dashboard are a common complaint. These can be caused by loose trim pieces, wiring harnesses, or other components.
    • What to do: Locating the source of the rattle can be tricky. Try pressing on different areas of the dashboard to see if you can pinpoint the source. You may need to remove trim pieces to access the area and secure the loose components.
  • Seat Problems: Some owners have reported issues with the seats, such as squeaking or difficulty adjusting.
    • What to do: Lubricating the seat tracks and hinges may resolve the squeaking. If the seat adjustment mechanism is faulty, it may need to be repaired or replaced.
  • Door Lock Actuator Failure: The door lock actuators can fail, preventing the doors from locking or unlocking properly.
    • What to do: Replacing the faulty door lock actuator is usually a relatively simple repair.

Other Common Issues: Don't Forget These!

  • Paint Problems: Some owners have reported issues with the paint, such as chipping or fading. This can be due to poor paint quality or environmental factors.
    • What to do: Regular washing and waxing can help protect the paint. If the paint is severely damaged, a professional paint job may be necessary.
  • AC Problems: AC issues, such as weak airflow or warm air, can occur. This can be caused by a refrigerant leak, a faulty compressor, or a clogged condenser.
    • What to do: Have the AC system inspected by a qualified technician. They can identify the source of the problem and recharge the refrigerant or repair the faulty components.
  • Steering Issues: Some owners have reported steering problems, such as a clicking noise or difficulty turning the wheel. This can be caused by a faulty power steering pump, a worn steering rack, or a problem with the suspension.
    • What to do: Have the steering system inspected by a qualified mechanic. They can identify the source of the problem and make the necessary repairs.
