The 2009 Elantra is generally reliable transportation, but the 2.0L four-cylinder can suffer catastrophic engine failure due to inadequate factory assembly and piston ring/bearing issues, particularly in earlier production batches. Transmission cooler leaks and electronic power steering faults are also noteworthy.
Catastrophic Engine Failure (Theta II 2.0L)
Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: metallic knocking or ticking from engine block, sudden loss of oil pressure, engine seizes without warning, excessive oil consumption before failure, metal shavings in oil during changes
Fix: Complete engine replacement or rebuild required. Metal debris from improperly finished crankshaft journals and defective piston rings circulate through oiling system, destroying bearings. Most shops opt for used/reman longblock (12-16 hours labor) rather than rebuild due to core condition. Hyundai extended warranty to 10yr/100k on some VINs but many 2009s fall outside coverage.
Estimated cost: $3,500-6,500
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: transmission fluid puddles under vehicle center-front, burnt transmission fluid smell, slipping or delayed shifts if fluid level drops, pink or red fluid on radiator area
Fix: Crimped fittings on cooler lines corrode and weep, or rubber hoses deteriorate. Replace cooler lines and top off ATF (1.5-2.5 hours). If driven low on fluid, internal transmission damage requires rebuild (adds 8-12 hours).
Estimated cost: $250-450
Electric Power Steering Motor Failure
Occasional · high severity
Typical onset: 70,000-130,000 mi
Symptoms: sudden complete loss of power steering assist while driving, EPS warning light illuminated, grinding or whining noise from steering column, intermittent assist loss that becomes permanent
Fix: Motor-driven EPS unit on column fails, leaving manual steering only (still driveable but heavy at low speeds). Replace entire EPS assembly (2-3 hours). Covered by NHTSA recall 13V-527 for some VINs—check if eligible before paying. Aftermarket units available but OE reman preferred.
Estimated cost: $650-1,200
ABS Module Failure
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: ABS and traction control warning lights steady on, loss of ABS function (normal braking remains), pump cycling noise at startup, occasional false ABS activation on dry pavement
Fix: Internal corrosion or solder joint failure in hydraulic control unit. Bleeding won't fix it—module replacement or rebuild required (2-2.5 hours). Some units covered under recall 18V-053; verify eligibility. Rebuilt modules widely available and work fine.
Estimated cost: $600-1,100
Transmission Mount Collapse
Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: clunking when shifting from park to drive or reverse, excessive engine movement visible during acceleration, vibration at idle in gear, shift lever feels harsh
Fix: Hydraulic transmission mount ruptures internally, allowing excessive powertrain movement. Replace mount (1-1.5 hours). Simple job but often ignored until it tears completely. Check all three motor mounts while underneath.
Estimated cost: $180-320
Brake Light Switch Failure
Common · medium severity
Symptoms: brake lights stuck on or not illuminating at all, cannot shift out of park (shift interlock affected), cruise control won't set or disengages randomly, push-button start won't work if equipped
Fix: Plastic switch at brake pedal cracks or contacts fail. Covered under recall 15V-106 for most 2009s—dealer replacement free. DIY takes 15 minutes. Critical safety item as drivers behind you can't see braking.
Estimated cost: $0-80
Owner tips
Change oil religiously every 5,000 miles with quality synthetic blend to maximize engine longevity—extended intervals invite bearing/ring issues on this motor
Check transmission fluid level every 20,000 miles and inspect cooler lines for seepage before they fail completely
If EPS light ever flickers, address immediately—full failure happens quickly and leaves you wrestling the wheel
Monitor oil consumption monthly after 60,000 miles; burning more than a quart between changes signals impending engine trouble
Decent cheap transportation if the engine hasn't failed yet, but treat any 2009 Elantra as a potential grenade after 80k miles—budget for engine replacement or walk away.

Remedy: Hyundai will verify the proper operation of the Electronic Power Steering (EPS) and update the EPS control unit, free of charge. The recall began April 14, 2015. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 127.
EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH · 13V113000
2013-04-01
Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Consequence: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.
