On the 2006-2011 Hyundai Elantra, nHTSA recall 20V061 covers certain 2006-2011 Hyundai Elantra and 2007-2011 Elantra Touring vehicles. Their ABS module remains energized after the vehicle is turned off; if moisture enters its electrical circuit, a short can gradually develop and cause an engine-compartment fire even with the car off.

Common Symptoms

  • An ABS-module short circuit may occur without advance warning
  • Engine-compartment fire can occur while the vehicle is turned off

How to Fix

Check the VIN for Hyundai Recall 188. Hyundai dealers install a relay in the main junction box, free of charge, to prevent an ABS short circuit while the vehicle is turned off.

On the 2001-2020 Hyundai Elantra, elantras run in road-salt regions suffer a consistent rear brake problem: the rear caliper piston and the caliper slide pins corrode and stop retracting, so the pads stay in light contact with the rotor. The tell-tale is rear pads wearing out faster than fronts - the reverse of the normal pattern on a front-heavy front-drive car - along with one rear wheel that is noticeably hot after a drive, a burning smell, a rotor with a blue heat ring, and a pull or shudder under braking. On cars with a drum-in-hat parking brake, the parking brake shoe expander and the cables also seize with rust, so the parking brake either will not release or will not hold. Owners report seizure as early as 60,000 km in salt country. Left alone it destroys rotors and pads repeatedly and can overheat the rear wheel bearing and hub.

Common Symptoms

  • Rear brake pads wearing out before the fronts
  • One rear wheel hot to the touch after driving
  • Burning smell after a drive
  • Grinding, squealing or shudder from the rear brakes
  • Parking brake will not release, or will not hold on a hill
  • Reduced fuel economy and a slight drag when coasting

How to Fix

Not a recall item. The correct service is to strip the rear calipers annually in salt regions: clean and re-lubricate the slide pins with high-temperature silicone brake grease, replace torn pin boots and the piston dust boot, clean the pad abutment slides and fit new stainless hardware clips. A piston that will not retract with a wind-back tool, or a bore with pitting, means the caliper is replaced rather than serviced. Free the parking brake cables and lubricate the expander, or replace the cables where the outer sheath has split and let water in. Where a caliper has seized, replace the rotor and pads on that axle in pairs. Preventive brake service each autumn is far cheaper than repeat caliper failure.

Typical repair cost:$250 - $900

On the 2007-2009 Hyundai Elantra, nHTSA recall 11V143 covers certain 2007-2009 Hyundai Elantra vehicles. Contamination can cause the electrical connector for the front-passenger weight-classification sensor to malfunction, allowing the passenger airbag to deploy regardless of occupant weight.

Common Symptoms

  • The passenger-airbag classification system may not respond correctly to occupant weight
  • The passenger airbag may deploy in a crash when it should remain suppressed

How to Fix

Check the VIN for Hyundai Campaign 099. Dealers install a protective cover over the weight-classification-system connector to prevent contamination, free of charge.

On the 2001-2020 Hyundai Elantra, elantras fitted with a sunroof route water that gets past the glass seal into four corner drains and down tubes inside the A-pillars and rear pillars. On cars parked under trees the corner drains silt up with pollen, leaf debris and dirt, and the tubes themselves can pull off their nipples or kink behind the trim. Water then backs up out of the sunroof tray and runs down inside the pillar into the front or rear footwell. Owners describe carpet that is soaking on one side after a heavy rain or a car wash, water sloshing under the mat, a musty smell, fogged glass that will not clear, and eventually mould in the padding. Because the water tracks along the sill, it can also reach body control and junction-block connectors and cause unrelated intermittent electrical faults, and on later cars it can soak the under-seat airbag wiring. It affects sunroof-equipped Elantras across generations, not just the panoramic-roof cars.

Common Symptoms

  • Wet or soaked carpet on the driver or passenger side after rain
  • Water dripping from the headliner or A-pillar
  • Musty or mouldy smell in the cabin
  • Windows fogging and not clearing
  • Unexplained intermittent electrical faults from wet floor connectors

How to Fix

Not a recall item - it is preventive maintenance. Open the sunroof and locate the four corner drain holes, then clear them with low-pressure compressed air or a soft trimmer line, never a stiff wire that can puncture the tube. Pour a cup of water into each corner and confirm it drains out behind the front wheels and at the rear. Where the tube has separated from its nipple or split, the trim must come off to reseat or replace the tube. Any wet carpet must be lifted and the jute padding dried or replaced - drying the carpet surface alone leaves the mould. Flush the drains once or twice a year, more often if the car is parked under trees.

Typical repair cost:$0 - $600

On the 2007-2020 Hyundai Elantra, on the Elantra's inline-4 (Beta II 2.0L in 2007-2010, Nu 2.0L in 2011+), P0171 means fuel trims have gone too positive because unmetered air is entering the engine. The classic Elantra trigger is a vacuum leak — most often a hardened/cracked PCV hose or a leaking intake-manifold gasket — followed by a contaminated mass-air-flow (MAF) sensor giving low airflow readings, or a stuck-open purge/PCV valve. A weak fuel pump or clogged injectors are less common but possible when fuel pressure drops below the ~49-53 PSI spec. Being an inline-4, the Elantra has only Bank 1, so this is the only lean-bank code it can set.

This issue also affects: Hyundai Excel, Hyundai Scoupe, Hyundai Sonata

Common Symptoms

  • Check engine light on
  • Rough or unstable idle
  • Hesitation or stumble on acceleration
  • Reduced fuel economy
  • Occasional hard start

How to Fix

Perform a smoke test to pinpoint the vacuum/intake leak, then replace the failed PCV hose, intake-manifold gasket, or PCV valve. Clean the MAF sensor with MAF-safe cleaner (or replace if it doesn't recover). Verify fuel pressure holds 49-53 PSI to rule out a weak pump or clogged filter/injectors. Clear codes and re-check long-term fuel trims (should return toward 0%).

On the 2007-2015 Hyundai Elantra, hyundai TSB 17-ST-002 covers 2007-2010 Elantra, 2009-2012 Elantra Touring and specified-production 2011-2015 Elantra vehicles. The flexible rubber coupling in the motor-driven power-steering assembly may wear and produce a slight clicking or thud noise while the steering wheel is turned. Hyundai states that this wear does not affect steering control and is not a safety issue.

Common Symptoms

  • Slight clicking noise while turning the steering wheel
  • Slight thud while turning the steering wheel

How to Fix

Have a Hyundai dealer confirm vehicle eligibility and diagnose the noise. The bulletin extends coupling coverage to 10 years or 100,000 miles, whichever occurs first, and describes replacement of the MDPS flexible coupling when required.
