Excessive oil consumption (2AZ-FE engine) — largely expired warranty coverage
Excessive oil consumption (1-4 quarts between changes), sulfur smell, rough idle
Check engine light: On
This vehicle's most significant engine problem: excessive oil consumption (1-4 quarts between changes) tied to the 2AZ-FE engine's piston rings, acknowledged by Toyota via TSB-0094-11 and covered under "Warranty Enhancement Program ZE7" (and a later Phase 2) for roughly 8 years/150,000 miles from original in-service date. For 2006-2012 RAV4s (now 14-20 years old), that coverage window has passed for the great majority of vehicles — meaning this is now a genuine out-of-pocket common problem for current owners, even though it began life as a Toyota-acknowledged, warranty-covered issue. Rough idle from this issue can trigger a check-engine light.
113,000 mi (example case)
Program ZE7 coverage (roughly 8 years/150,000 mi from the original in-service date) has passed for the great majority of this generation. That is based on the program's term length rather than a single published end date, so check your own eligibility.

Throttle lag
Delayed throttle response
Check engine light: On
Delayed throttle response, resolved via ECM reprogramming at just 10,000 miles — very early-life. An ECM reprogramming case like this typically follows a check-engine light.
10,000 mi
Very early-life (10,000 mi), resolved via a software fix rather than a parts replacement.

Catalytic converter issue
"Sulfur smell"
Check engine light: On
A sulfur smell tied to catalytic converter replacement, reported twice at notably different mileages. A catalytic converter fault triggers a check-engine light.
14,000 mi and 65,000 mi (2 documented cases)

Idler pulley bearing failure
High-pitched noise
Check engine light: Off
One documented idler pulley bearing failure causing a high-pitched noise, at 33,000 miles. A bearing/noise fault like this doesn't typically trigger a check-engine light.
33,000 mi

O2 sensor failure
Check engine light
Check engine light: On
One documented downstream O2 sensor replacement at $500 at 70,700 miles, with a check-engine light explicitly reported. By definition, this problem involves a check-engine light.
$400 – $55070,700 mi

Coolant overflow
Antifreeze smell
Check engine light: Off
One documented coolant overflow case — an antifreeze smell — at just 3,000 miles, resolved by draining excess coolant and a pressure test. This very early-life case reads as a minor overfill issue rather than a defect. Not typically a check-engine-light fault on its own.
3,000 mi
Very early-life (3,000 mi) — reads as a minor overfill issue rather than a defect.

Steering column clunk (intermediate steering shaft U-joint wear)
Clunking or popping noise through the steering wheel at low speed or during stationary turns, felt play in the wheel
Check engine light: Off
Widely reported on this generation: premature wear in the U-joints of the intermediate steering shaft, a separate component connecting the interior column to the engine-bay steering rack (not a main column failure). Toyota acknowledged this via Technical Service Bulletin T-SB-0033-11 ("Popping or Clunk Type Noise from the Steering Column Area"), directing dealers to replace the shaft with an improved part -- but owners report Toyota has treated it as out-of-warranty and not a safety issue, so this is largely an out-of-pocket repair for current owners. NHTSA complaints describe "steering column clunking, loose steering wheel, failed welds," and the problem is reported across both the 2006 and 2008 model years.
31,000 mi (earliest reported case); widely reported across the generation
Distinct from the two suspension-arm recalls below -- this is the intermediate steering shaft, a separate part not covered by either recall campaign.

Front strut/shock premature failure
Leaking or failed front struts/shocks, clunking or rough ride, uneven tire wear
Front struts and shocks reported leaking or failing well inside a normal service interval on both four-cylinder and V6 trims, sometimes paired with front hub/wheel-bearing replacement in the same repair visit. One documented case at 150,000 mi combined struts, caps, and tie rod ends in a single $4,000 repair. Cost distribution across broader suspension-category repairs (2006 model year): nearly half (48%) of suspension repairs cost under $100, 30% fall in the $100–$499 range, and only 3% exceed $2,500 -- so the high-cost cases are the exception, not the rule.
36,000–166,000 mi (wide range across documented cases)

Rear wheel bearing failure
Grinding or humming noise from the rear of the vehicle, worsening with speed or turns
Rear wheel bearings reported failing across a wide mileage range on both four-cylinder and V6, AWD and FWD trims -- sometimes on one side only, sometimes replaced on both sides in the same visit. Several cases were still within Toyota's original warranty; others were owner-paid out-of-warranty repairs.
24,000–125,000 mi (wide range; some warranty-covered)

Sway bar end link failure (corrosion)
Clunking or rattling noise over bumps, loose-feeling handling
Sway bar end links and bushings reported failing or breaking, with at least one owner explicitly attributing it to corrosion ("sway bar end bolts corroded from poor design"). This is a lower-severity, lower-cost problem than the other suspension items above, but it recurs across multiple model years.
62,000–84,000 mi (documented cases)

Radio/head unit display failure
Garbled, unreadable, or intermittently blank radio/stereo display; unresponsive preset buttons; radio not turning off
Early-life radio/head-unit display failures -- garbled or unreadable LCD text, intermittent blanking, and unresponsive controls -- reported on both 2006 and 2007 model-year cars, all within the first 15,000–20,000 miles and resolved under Toyota's original warranty via full radio replacement. No reports describe this recurring later in a vehicle's life or as an out-of-pocket repair.
5,000–18,250 mi (all early-life, warranty-covered cases)

Intermittent starting problems (battery cable corrosion / neutral safety switch)
Intermittent difficulty starting or a no-start condition
Two distinct root causes documented for intermittent starting complaints on this generation: corrosion at the negative battery post/cable connection in one case, and a faulty neutral safety switch causing intermittent starting in another. They are grouped here because they produce the same symptom, but they are not confirmed to share a cause -- treat them as two possible explanations for a car that won't start.
9,000–48,000 mi (documented cases)
Two distinct root causes (battery cable corrosion vs. neutral safety switch) grouped here under one symptom; they are not confirmed to share a cause.

Rear door latch failure
Rear door will not latch or unlatches unexpectedly
A rear door latch failure documented at very low mileage (9,000 mi) with a notably high repair cost ($900) relative to the vehicle's age at the time -- more consistent with an isolated part defect than a wear item. Only one case is documented, so treat this as a possible issue rather than a confirmed common problem.
9,000 mi (single documented case)
Based on a single report, unlike the other problems listed for this vehicle. The unusual cost at such low mileage is what makes it worth knowing about.

This page covers engine problems (33% of repairs, the largest category) in the most depth. Electrical, suspension, brake, transmission and body problems are not yet covered to the same level. The main problem to know about is excessive oil consumption on the 2AZ-FE engine. Toyota's Warranty Enhancement Program ZE7 covered it for roughly 8 years/150,000 miles from original in-service date, a window that has now passed for the great majority of these vehicles.
