The 2004 Camry is generally reliable, but the 4-cylinder models suffer from catastrophic oil consumption issues that can destroy engines, while both engines share typical high-mileage transmission and cooling problems.
Symptoms: Burning 1+ quart of oil every 1,000 miles with no visible leaks, Blue smoke from exhaust on startup or acceleration, Check engine light for catalyst efficiency codes (P0420/P0430), Fouled spark plugs, rough idle, eventual engine seizure if oil runs dry
Fix: Piston rings carboned-up from design flaw. Only real fix is engine rebuild with updated pistons/rings (18-24 labor hours) or used/reman engine swap (12-16 hours). Band-aid: frequent oil top-ups and spark plug changes every 15k miles.
Estimated cost: $3,500-5,500
Transmission Oil Cooler Line Corrosion and Leaks
Common · medium severity
Typical onset: 100,000-180,000 mi
Symptoms: Red fluid puddles under vehicle, typically passenger side near radiator, Transmission slipping or delayed engagement when fluid gets low, Burnt transmission smell if driven while low on fluid
Fix: Steel lines rust through where they connect to radiator. Replace both cooler lines and top off transmission fluid (2-3 hours). Check radiator end tanks for cracks while you're there—often corroded too.
Estimated cost: $350-600
Automatic Transmission Mount Failure (Front Mount)
Common · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Loud clunk when shifting from Park to Drive or Reverse, Excessive vibration at idle, especially with A/C on, Engine visibly rocking back and forth during acceleration
Fix: Hydraulic front engine mount collapses, allowing drivetrain to slam around. Replace mount—straightforward job but requires supporting engine (2-2.5 hours). Inspect other mounts while you're in there.
Estimated cost: $250-400
Evaporative Emissions System Leaks (Charcoal Canister/VSV)
Occasional · low severity
Typical onset: 120,000+ mi
Symptoms: Check engine light with codes P0440, P0441, P0446, Fuel smell near rear of vehicle or inside cabin, Difficulty fueling—pump clicks off repeatedly
Fix: Charcoal canister saturates or cracks, VSV (vapor switching valve) sticks. Smoke test to locate leak (0.5 hours), then replace failed components. Canister lives under rear bumper, pain to access (1.5-2 hours total).
Estimated cost: $300-550
Steering Intermediate Shaft Clunk
Occasional · low severity
Typical onset: 80,000-150,000 mi
Symptoms: Clunk or knock from steering column when turning at low speeds (parking lots), Felt through steering wheel, not suspension-related, More noticeable in cold weather
Fix: Universal joint in intermediate shaft wears out, needs lubrication or replacement. Lube job (0.5 hours) is temporary; proper fix is new shaft (1.5 hours). Not a safety issue, just annoying.
Estimated cost: $200-450
A/C Compressor Clutch Bearing Failure (3.0L V6 more common)
Occasional · medium severity
Typical onset: 110,000-160,000 mi
Symptoms: Squealing or grinding noise from engine bay, worse with A/C on, A/C intermittently blows warm air, Bearing can seize and snap serpentine belt, killing alternator/water pump
Fix: Clutch bearing or entire compressor fails. If caught early, replace compressor only (2.5-3 hours). If belt snaps, add belt and possible water pump damage. Evacuate/recharge A/C system adds 1 hour.
Estimated cost: $650-1,100
Lower Ball Joint Wear (Especially in Rust Belt)
Occasional · high severity
Typical onset: 100,000-180,000 mi
Symptoms: Clunking over bumps from front suspension, Tire wearing unevenly on inside edge, Steering wanders or feels loose, Ball joint can separate catastrophically—wheel folds under
Fix: Ball joints not serviceable separately—requires entire lower control arm replacement per side (2 hours per side). Must do alignment afterward. Inspect regularly above 100k miles.
Estimated cost: $400-700 per side
Owner tips
If buying a 2.4L 4-cylinder, check oil consumption immediately—do the math on dipstick between fillups. Walk away if it's burning more than 1 qt per 1,500 miles.
Change transmission fluid every 50k miles using Toyota Type T-IV (or WS for later builds)—extends transmission life significantly.
Inspect transmission cooler lines and radiator end tanks annually after 100k miles, especially in salt states.
Keep detailed oil change records if you have the 4-cylinder—helps with potential warranty extensions or resale transparency.
Excellent used buy IF you avoid 4-cylinder models or verify zero oil consumption—V6 versions are rock-solid and cheap to maintain.

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004 AVALON VEHICLES; 2004 AND 2005 CAMRY, CAMRY SOLARA, HIGHLANDER, AND SIENNA VEHICLES, 2006 HIGHLANDER HYBRID; 2004 AND 2005 LEXUS ES330 AND RX330; AND 2006 LEXUS RX400H VEHICLES MANUFACTURED FROM JUNE 1, 2004 THROUGH MARCH 31, 2005, EQUIPPED WITH THE 1MZ-FE OR 3MZ-FE ENGINE. THE AMOUNT OF ADHESIVE AGENT APPLIED BETWEEN THE OUTER RING AND THE TORSIONAL RUBBER DAMPER (INNER RING) IN THE CRANKSHAFT PULLEY MAY BE INADEQUATE. IF THE ADHESIVE IS INSUFFICIENT, THERE IS A POSSIBILITY THAT THE OUTER RING MAY BECOME MISALIGNED AND IT MAY NOT PROPERLY ROTATE WITH THE INNER RING, CAUSING NOISE AND/OR ILLUMINATION OF THE BATTERY DISCHARGE INDICATOR LIGHT.
Consequence: IN SOME CASES, THE BELT FOR THE POWER STEERING PUMP MAY BECOME DETACHED FROM THE PULLEY WHICH COULD RESULT IN A LOSS OF POWER STEERING AND A SUDDEN INCREASE IN STEERING EFFORT, INCREASING THE RISK OF A CRASH.
Remedy: TOYOTA WILL NOTIFY OWNERS, AND DEALERS WILL CHECK THE CRANKSHAFT PULLEY TO IDENTIFY WHETHER IT WAS PRODUCED BY THE U.S. SUPPLIER. IF SO, THE DEALER WILL REPLACE THE PULLEY WITH A NEW ONE AT NO CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING EARLY JANUARY 2012. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.
SEAT BELTS:FRONT:BUCKLE ASSEMBLY · 04V595000
2004-12-15
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A FRONT PASSENGER POWER SEAT, WHEN INSTALLING CERTAIN REAR-FACING INFANT CHILD SEAT BASES ONTO THE SEAT WITH AN EXCESSIVELY HIGH SEATBELT TENSION, IT MAY BE POSSIBLE TO UNSEAT A COMPONENT CALLED THE BUCKLE STATUS SWITCH FROM THE SEAT BELT BUCKLE.
Consequence: IF THE SWITCH BECOMES UNSEATED, THE FRONT PASSENGER OCCUPANT CLASSIFICATION SYSTEM MAY MISTAKE THE REAR-FACING CHILD RESTRAINT FOR AN UNBELTED ADULT OCCUPANT, AND MAY NOT SUPPRESS THE DEPLOYMENT OF THE FRONT PASSENGER AIRBAG.
Remedy: DEALERS WILL REPLACE THE FRONT PASSENGER SEATBELT BUCKLE STATUS SWITCH. THIS SAFETY IMPROVEMENT CAMPAIGN (SSC 40M) BEGAN ON DECEMBER 20, 2004. OWNERS SHOULD CONTACT TOYOTA AT 1-800-331-4331 OR LEXUS AT 1-800-255-3987..
AIR BAGS:SIDE/WINDOW · 04V346000
2004-07-13
ON CERTAIN VEHICLES EQUIPPED WITH CURTAIN SHIELD AIR BAGS (CSA), ONE OR BOTH OF THE CURTAIN AIR BAGS MAY BE TWISTED NEAR THE INFLATOR DUE TO IMPROPER ASSEMBLY.
Consequence: IF THIS OCCURS, THE CSA MAY NOT DEPLOY RAPIDLY ENOUGH WHEN ACTIVATED IN A SIDE IMPACT COLLISION. THIS MAY RESULT IN FAILURE TO PROVIDE THE INTENDED HEAD PROTECTION, INCREASING THE RISK OF INJURY.
Remedy: DEALERS WILL INSPECT THE CSAS AND REPLACE THE AIR BAG ASSEMBLY IF NECESSARY. THE RECALL BEGAN ON AUGUST 6, 2004. OWNERS SHOULD CONTACT TOYOTA AT 1-800-331-4331.
