Common problems: Check engine light issues are fairly common, especially with the EVAP system. Often the repair involves replacement of the charcoal canister, which is quite expensive. Reports suggest that replacing only the EVAP vacuum switching valve (VSV) mounted at the canister can fix the problem in some cases. Replacing the VSV only is a lot cheaper.

Loose solder joints at the circuit board behind the temperature control knob can cause heater and A/C issues where the air temperature changes by itself. This page illustrates the heater control repair. Some airbag issues are also reported in earlier models. There are several reports about water pump failures in 2006 and 2007 models. Don't get the wrong picture looking at these issues, overall the Highlander is rated well above average for reliability by Consumer Reports.

What to look for when buying a used Toyota Highlander: Avoid cars after accidents and those that appear to be neglected. Run the used car history check. It's a big plus if you can verify through the service records that recommended maintenance has been followed. The V6 Highlander has a timing belt; if it has not been replaced by the previous owner, you are looking for additional $500-800 to spend. If there are any signs that the engine has been overheated, avoid the vehicle. Blue smoke from the exhaust and oil leaks are other signs of potential problems. We strongly recommend to have the vehicle inspected by your mechanic before purchase.

Maintenance: Overheating can result in a very expensive engine repair. If you notice the temperature gauge rises more than normal, have the issue checked out before it causes a major problem. Regular oil changes will ensure your engine will last longer. Toyota recommends 5W-30 oil for both 4-cylinder and V6 engines in the 2001-2006 Highlander. However, in the 2007 model, 5W-20 or 0W-20 is the recommended viscosity for the 2.4L 4-cylinder 2AZ-FE engine. The 2007 V6 Highlander still needs 5W-30 oil. You can find details in "Specification" section of your owner's manual. An electronic copy of the owner's manual can be accessed at the US Toyota Owners website. Check your tire pressure regularly; unequal tire pressure between tires will cause increased wear of 4WD system components.
