2006 Toyota RAV4 Problems
RepairPal has identified the most common problems with the 2006 Toyota RAV4 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.
Drivers of the Toyota RAV4 may notice excessive oil consumption between oil changes, even to the extent of the engine oil warning light displayed on the multi-function display.
This issue is known to be caused by infrequent oil changes causing engine sludge, or worn piston rings.
The engine should be cleaned of oil sludge, and if oil consumption remains excessive, the engine may need new piston rings, or other internal components replaced.
To avoid this issue, change the engine oil and filter every 3,000 miles, and ensure the proper grade of oil is used.
The head gasket may fail due to a defect in manufacturing of the cylinder block.
On this vehicle, the head bolts are known to pull the threads out of the engine block, allowing the head to slightly lift, and causing head gasket failure. Symptoms may include:
- White smoke from exhaust
- Rough running conditions and/or inability to start or idle
- White or cream colored oil on dipstick
- Check engine light
- OBD Trouble Codes P2181, P0300
When the head gasket fails, the bolt holes for the head bolts must be repaired before the cylinder head can be remounted.
This issue is not always preventable, but to help avoid it, never run the engine if the engine temperature is ever above the normal range.
The VVT-i oil line is known to burst. This is a very large leak which covers the ground, engine, and undercarriage.
If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate. Continued use after these warnings will result in complete engine failure due to oil starvation.
The line is known to be defective, and a revised part has been issued by Toyota, however, this revised part is known for the same issue.
To repair the issue, the line must be replaced, and the engine bay and undercarriage must be cleaned thoroughly.
There is a tendency to warp the front rotors. This will be felt as a shudder in the steering wheel when braking. The front rotors can be remachined, if there is sufficient material left, otherwise the front rotors will need to be replaced. It is recommended to use factory quality rotors because cheap quality rotors warp very easily and tend to squeak and squeal.
The engine mount on the driver side of the car can wear out on cars with high mileage. This will put extra stress on the other mounts and the faulty mount will need to be replaced.
