The 2002 Santa Fe represents Hyundai's first-generation SUV effort — generally reliable bones but plagued by catastrophic 2.7L V6 engine failures and chronic transmission cooling issues that can bankrupt uninformed buyers.
Symptoms: Knocking or ticking from engine bay that worsens with RPM, Metal shavings in oil during changes, Sudden loss of oil pressure followed by seizure, Check engine light with misfire codes before catastrophic failure
Fix: Complete engine replacement or rebuild required — connecting rod bearings fail due to inadequate oiling and debris contamination. Rebuild requires 18-24 labor hours including machine work; used engine swap 12-16 hours. Many shops won't touch rebuilds on these due to pattern failures.
Estimated cost: $3,500-6,500
Transmission Oil Cooler Line Failure and Fluid Cross-Contamination
Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Pink milkshake appearance in coolant reservoir (ATF mixing with coolant), Transmission slipping or delayed engagement after engine overheats, Coolant level drops with no visible external leaks, Transmission fluid appears brown or has coolant smell
Fix: Internal transmission cooler in radiator fails, allowing coolant and ATF to mix — destroys transmission if not caught early. Requires radiator replacement (3 hours), full cooling system flush (1.5 hours), transmission fluid flush minimum (2 hours). If cross-contamination occurred, transmission rebuild/replacement adds 10-14 hours.
Transfer Case and Front Differential Fluid Leaks (AWD Models)
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Fluid puddles under center/front of vehicle, Whining or grinding noise during turns, Binding sensation when making tight turns on dry pavement, AWD warning light illuminates
Fix: Input and output shaft seals fail on transfer case; front differential pinion seals also problematic. Transfer case seal replacement 4-6 hours (requires case removal on some configurations). Differential seal 2-3 hours. Neglect leads to bearing damage requiring full unit replacement.
Typical onset: 90,000+ mi or salt-belt vehicles sooner
Symptoms: Clunking noise over bumps from front suspension, Vehicle sits noticeably lower on one side, Visible break in spring coils during inspection, Tire wear becomes uneven suddenly
Fix: Front coil springs fracture due to corrosion (especially salt belt) — subject to recall but many vehicles never fixed. Spring replacement 2.5-3 hours per side, requires alignment (1 hour). Always replace both sides and inspect for strut mount damage from broken spring impacts.
Estimated cost: $600-900
Crankshaft Position Sensor Failure
Common · high severity
Typical onset: 60,000-150,000 mi
Symptoms: No-start condition, cranks but won't fire, Stalling at idle or while driving with no restart, Intermittent stalling that becomes more frequent, Check engine light with P0335 or P0336 codes
Fix: Sensor fails from heat cycling — leaves you stranded without warning. Located behind starter on V6 models; requires starter removal for access. Labor 2-3 hours including diagnostic time. Sensor itself is cheap ($40-80) but location is a pain. Keep a spare in the glovebox if keeping this vehicle long-term.
Estimated cost: $250-450
Rear Suspension Trailing Arm Bushing Deterioration
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking from rear over bumps, Wandering or unstable feeling at highway speeds, Uneven rear tire wear on inside edges, Rear end feels loose or disconnected on rough roads
Fix: Trailing arm bushings deteriorate and tear — affects handling and alignment. Replacement requires pressing out old bushings and pressing new ones in; 3-4 hours labor for both sides plus alignment (1 hour). Some techs replace entire trailing arms with bushings pre-installed to save press time.
Estimated cost: $500-850
Owner tips
On 2.7L V6 models, use ONLY genuine Hyundai oil filters — aftermarket filters have caused accelerated bearing wear due to inadequate filtration
Check transmission and coolant fluids every oil change for cross-contamination; catching pink coolant early saves $3,000+
Inspect front coil springs annually in salt-belt states; recall 06V063000 covers this but many vehicles never got the fix
AWD models: service transfer case and front differential every 30,000 miles regardless of manual recommendations — these units are marginal
2.4L four-cylinder is far more reliable than either V6; prioritize this engine if shopping used
Hard pass on 2.7L V6 models — engine grenades are a matter of when, not if. 2.4L four-cylinder versions are acceptable budget transport if transmission cooler has been addressed and you can verify religious maintenance history.

Hyundai Motor Company (Hyundai) is recalling certain model Year 2001-2006 Santa Fe vehicles manufactured from March 31, 2000, through February 15, 2006, that are registered and operated, or which were originally sold and registered, in the following 20 salt belt" states and the District of Columbia: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The affected vehicles may experience front coil spring corrosion from road salt, causing the coil spring to fracture and make contact with the tire.
Consequence: If the front coil spring fractures due to corrosion it could cause the coil spring to make contact with the tire, possibly puncturing the tire and increasing the risk of a vehicle crash.
Remedy: Hyundai will notify owners, and dealers will inspect and if necessary replace the coil spring, free of charge. The recall began on October 24, 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 124.
SUSPENSION:REAR · 09V123000
2009-04-16 · EA08023
HYUNDAI IS RECALLING 83,355 MY 2001-2003 SANTA FE VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA. ROAD SALT APPLIED IN THESE JURISDICTIONS DURING THE WINTER MONTHS MAY RESULT IN PROGRESSIVE, INTERNAL CORROSION OF THE REAR TRAILING ARMS, WHICH COULD LEAD TO THINNING OR PERFORATION OF THE REAR TRAILING ARM STEEL. OWNERS MAY SEE OR FEEL SLIGHT TO MODERATE CHANGES IN VEHICLE OPERATION WHICH WILL INCREASE IF THE VEHICLE IS NOT REPAIRED. THESE CHANGES INCLUDE A LOWERING OF VEHICLE HEIGHT THAT CAN LEAD TO TIRE MISALIGNMENT AND STEERING PULL. OWNERS MAY ALSO NOTICE A CREAKING SOUND.
Consequence: IF THE CORROSION IS ALLOWED TO PROGRESS, THE REAR TRAILING ARM MAY FRACTURE WHILE DRIVING, THEREBY INCREASING THE RISK OF A VEHICLE CRASH.
Remedy: DEALERS WILL INSPECT THE REAR TRAILING ARMS FOR INTERNAL CORROSION DAMAGE. IF SPECIFIED LEVELS OF CORROSION DAMAGE ARE FOUND, THE REAR TRAILING ARMS WILL BE REPLACED. REAR TRAILING ARMS THAT DO NOT REQUIRE REPLACEMENT WILL HAVE DRAINAGE HOLES ADDED AND WILL BE TREATED WITH RUST-PROOFING MATERIAL TO ARREST THE CORROSION PROCESS. INSPECTION, TREATMENT AND REPLACEMENT PROCEDURES WILL BE CONDUCTED AT NO COST TO OWNERS. THE RECALL IS EXPECTED TO BEGIN DURING MAY 2009. OWNERS MAY CONTACT THE HYUNDAI CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.

CERTAIN SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS."
Consequence: THE TIRE PRESSURE LABELS DO NOT CONTAIN THE INFORMATION REQUIRED BY THE STANDARD.
Remedy: OWNERS WILL BE PROVIDED WITH A CORRECT LABEL AND INSTALLATION INSTRUCTIONS. OWNER NOTIFICATION BEGAN ON OCTOBER 29, 2003. OWNERS SHOULD CONTACT HYUNDAI AT 1-800-633-5151.
ELECTRICAL SYSTEM:STARTER ASSEMBLY · 03V030000
2003-01-02
ON CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH 2.7 LITER V-6 ENGINES, IMPROPERLY MANUFACTURED CRANKSHAFT POSITION SENSORS (CPS) WERE INSTALLED. THE CPS CASES WERE IMPROPERLY MANUFACTURED AND DID NOT MEET DIMENSIONAL SPECIFICATIONS. INTERNAL GAPS WITHIN THE CASES ALLOWED EPOXY TO CONTACT THE PRINTED CIRCUIT BOARD, WHICH RESULTED IN CRACKING OF THE PRINTED CIRCUIT BOARD CAPACITOR.
Consequence: A DAMAGED CPS CAPACITOR COULD RESULT IN ENGINE STALLING.
Remedy: DEALERS WILL REPLACE THE CPS. OWNER NOTIFICATION BEGAN ON MARCH 10, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT HYUNDAI AT 1-800-829-9956.
