MyV6 highlander has 70,000 miles and never given me a problem in the 10 months I have had it.
The following is the sequence of events-strange.
I left my 10 yr old grandaughter sitting in the parked car with the ign key in the accessory position and radio on. After 10 minutes she left the car and brought me the keys-I was sitting in the shade around a corner about 40 feet away.
After a few minutes she asked what would happen if I pressed the panic button on the remote. I pressed it to show her as we approached the car. However, the horn did not blow and lights did not flash, but when I was 20 ft from the car I heard the condenser fan running, and when I reached the car, realized the the engine was running! I put the key in the ignition, and turned it to accessory position - engine still ran, then turned of the key to lock position - engine still ran. Then I turned to start position which caused the starter pinion to hit the flywheel and then turned back to the off
position. Engine turned off and has been running fine ever since(2 days). Panic device appears to operate normally.

Turn the ignition key to the "ON" position without starting the engine.
Press the button to the left of the display on the instrument panel twice within one second. The oil life status will be displayed on the panel -- this should be past the mileage due for the service interval if the wrench icon is illuminated
Turn the ignition key to the "OFF" position within 10 seconds of the status display.
Press and hold the button to the left of the display again with one hand while turning the ignition key back to the "ON" position without starting the engine. The oil life status will show once again
Continue to hold down the button for a few seconds longer, and then release it. Wait 10 seconds until a chime indicates and displays 6,000 miles for at least another 10 seconds.
GM OIL LIFE SYSTEM - RESETTING The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the "CHANGE OIL SOON" light may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 16 000 km (10,000 miles) or 12 months without an oil change.
Reset the oil life monitor when the oil has been changed, use the following procedure:
Turn the ignition key to the RUN position.
Fully push and release the accelerator pedal 3 times within 5 seconds.
If the Change Oil Soon light flashes, the system is resetting.
Start the vehicle.
The oil life will change to 100%.
If the Change Oil Soon light comes back on, the system has not reset. Repeat the procedure.
You should change your engine oil and oil filter at 3000 miles with a good brand engine oil then change it every 5000 miles or 6 months which ever comes first.
Good luck and thanks for your question and I hope my suggestions help. Don't forget to rate me. burdfrenzy

i would chande the plugs at or around 60,000 to 70,000 miles. this is about the correct mileage. they may last longer but not worth the expensence of converter damage due to misfire and also gas mileage loss.
Hello, and welcome to FixYa. Without knowing the actual 'code' (the reason for the light being on), it is hard to state with any accuracy.
However...we see quite a bit, here in my shop, Highlanders with the Check Engine light on, right after an oil change. Often, whoever changes the oil sometimes checks the air filter, and, when they open the filter box, they knock off a vacuum hose going to the air filter box. This could be your problem.
Go out to the vehicle, pop the hood, and check the black box that holds the air filter, on the passenger side front of the engine compartment; look to see if a black rubber hose is not connected. If it is off, reconnect it and drive the vehicle 10 miles, shut it off, and drive another 10 miles. This may extinguish the light.
I hope that this info helps you out. Thanks for choosing FixYa for assistance.
error definitely some issues with the early six-cylinder timing belts. There were some updates, including a dampener for one of the cams. See if you can get copies of the service bulletins for your engine. I think the belt may also be somewhat wider on the later engines. DO NOT use the later interval.
