The 2009 Tucson is a mixed bag: the 2.0L four-cylinder is generally reliable if maintained, but the 2.7L V6 has serious bottom-end problems that can grenade engines at surprisingly low mileage. Transmission cooling and mount issues are common to both.
Symptoms: Deep knocking sound on cold starts that may fade when warm, Metallic rattling under acceleration, Low oil pressure warning, Complete engine seizure in worst cases
Fix: The 2.7L Delta V6 suffers from inadequate oiling to rod and main bearings, often caused by sludge buildup or poor oil maintenance, but failures occur even with good service history. Requires complete engine rebuild (16-20 hrs) or used/remanufactured engine swap (12-16 hrs). Many shops recommend replacement over rebuild due to core design issues.
Estimated cost: $3,500-6,500
Transmission Oil Cooler Lines Leak and Cooler Failure
Common · medium severity
Typical onset: 70,000-130,000 mi
Symptoms: Transmission fluid puddles under vehicle, typically near radiator, Burnt transmission smell, Harsh or delayed shifting when trans overheats, Pink/red fluid mixing with coolant (cooler internal failure)
Fix: The external cooler lines rust through where they route near the subframe, and the radiator-integrated cooler can fail internally, cross-contaminating fluids. External line replacement is 1.5-2 hrs; if coolant contamination occurred, requires transmission flush, radiator replacement, and possibly transmission rebuild. Catch it early and you're looking at lines and fluid; catch it late and you're rebuilding the transmission.
Symptoms: Loud clunk when shifting from Park to Drive or Reverse, Excessive engine movement visible when accelerating, Vibration at idle that changes when shifting to Drive, Transmission shifter feels notchy
Fix: The front transmission mount (also called the roll restrictor mount) uses a hydraulic design that fails, allowing excessive drivetrain movement. Replacement is straightforward: 1.5-2 hrs with the right jack placement to support the transmission. Use OE or quality aftermarket; cheap mounts fail within a year.
Symptoms: Brake lights stay on continuously, draining battery, Brake lights don't illuminate at all, Cannot shift out of Park, Cruise control won't engage or disengage
Fix: Even post-recall, the brake light switch above the pedal fails due to poor design and pedal bushing wear that causes misalignment. The switch itself is a 0.3-0.5 hr job, but many techs also replace the pedal bushings (add 0.5 hr) to prevent recurrence. This is safety-critical: no brake lights means rear-end collision risk, and a stuck-on switch kills the battery overnight.
Estimated cost: $120-250
Fuel Filter Clogging and Fuel Delivery Issues
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Intermittent stalling or hesitation under load, Hard starting after sitting, Loss of power on highway pulls, Check engine light with lean codes (P0171/P0174)
Fix: The in-tank fuel filter and pump strainer clog prematurely, especially in areas with ethanol fuel or if the tank has been run low frequently (stirring up sediment). Unlike older designs with external filters, this requires fuel pump assembly removal from the tank: 2-3 hrs. Some techs replace just the strainer; others do the whole pump assembly to avoid a comeback.
Estimated cost: $400-750
Timing Belt and Water Pump Failure (2.7L V6)
Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Squealing or chirping from front of engine, Coolant weeping from water pump area, Sudden no-start with bent valves if belt breaks (interference engine)
Fix: The 2.7L is an interference engine with a 60k-mile timing belt interval that owners often ignore. Water pump is driven by timing belt and should always be replaced at belt service (standard practice). If the belt snaps, expect valve damage requiring head work. Timing belt service is 4-5 hrs; belt breakage adds head removal and valve replacement, pushing it to 12-16 hrs total.
Estimated cost: $600-900 (preventive service), $2,500-4,000 (after belt failure)
Owner tips
If buying the V6, get a pre-purchase inspection with oil analysis and listen carefully for ANY bottom-end noise—walk away if present
Change engine oil every 3,750-5,000 miles on the 2.7L V6 regardless of monitor; sludge kills these engines
Do the timing belt at 60k on the V6, no exceptions—this is not a 'wait until 75k' situation
Inspect transmission cooler lines and radiator for leaks every oil change; early catch saves the transmission
Replace brake light switch pedal bushings when doing the switch to prevent misalignment and repeat failures
The 2.0L four-cylinder is a decent budget SUV if maintained; avoid the 2.7L V6 unless you can verify fanatical oil change history and accept engine replacement risk.

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.
