We have a 2001 Highlander V4 that I bought new from the dealership. Check engine light came on after about 30,000 miles. Dealership replaced the catalytic converter system for no charge because we were still in warranty. About 100 miles down the road, the check engine light came back on. Dealership reset everything, light went off. About 50 miles down the road, light came back on. Dealership said don't worry about it. After we went out of warranty and were at same dealership for routine service, I asked about the check engine light and was told it would cost $300 for full diagnostics and then additional for whatever repairs were needed. Took Highlander in for recall of the valve thing. Check engine light off. About 15 miles down the road, the light came back on. Took car to dealership because of silver-gray smoke coming out of exhaust on startup every morning. Mechanic started up the engine, observed the smoke and said I needed an engine overhaul -- $5,000. I took the Highlander to a small shop mechanic who said don't worry about it. I've switched to a higher grade of gasoline and am still driving the vehicle -- 140,000 miles. But my experience with this vehicle and dealership have turned me against Toyota forever. It's a shame because I used to have a 1978 Toyota Corolla that I could probably still be driving. It was a great little car -- no problems. From a lot of the posts I've read on this site and others, it seems that Toyota's famous quality reputation is being tarnished by shoddy systems and uncaring, incompetent dealership service departments.

I have to say that I feel like I'm reading about our car and our experience. It seems to run fine, but the check engine light will come on, then go off, then come on again. The dealership said they THOUGHT it might be the catalytic converter (before the warrenty ran out), but elected to replace both oxygen sensors instead, which killed the light for a while. The light stayed out for a time, but it's on and off again now, and the dealership is back to the catalytic converter theory. Unfortunately, the car's out of warranty now and I'm not too sure I want to push that much money into it now. We've got the smoke at start-up going on as well. Guess we'll just drive it until it stops and put electrical tape of the check-engine light!
Anything new going on with your Highlander?

Yep, all problems sound alike. I too was told that it might be the catalytic conveter, but since I had alreadyspent so much money on it, decided not to replace it. I was really disappointed with this vehicle and have recently traded it in.

i have a 2003 4cyl, my check engine light kept coming on and going off as well. i used a home diagnostic machine and it said both bays in my catalytic converter. i took my HL in after it coming on & going off several times and found out there was a recall. apparently something to do with my computer needing to be fixed. any of you that hasn't had your recall done needs to. the dealership can figure look up your vin and tell you if it has been.
my HL has been just fine without any scary check engine lights... until this morning hopefully it's nothing :::crossing fingers:::.

please post what year your Highlander is when posting a problem or comment. It would be very helpful in trying to give an answer. Different years make a difference.

I have a 2003 Toyota Highlander which I recently had a 60000 mile service. A few days later my check engine light came on. I took it to an auto parts store which performed a simple diagnostics test and told me it was something with the emissions. He suggested my gas cap was not tight, he reset it, that lasted 2 days and it came on again. Someone else suggested a bad EPR valve?? Any suggestions and could it have something to do with the recent major service at 60000 miles??

Do you know what code the computer is throwing? The simple reader should display it along with the system affected.
I generally don't trust the minimum wage employees at the parts store to give me an accurate assessment of the problem so I bought an ACTRON Scan Tool from the auto parts store, about $150, works for every vehicle manufactured beginning in 1996. The tool will give you a code(s) readout plus give a status rundown of all the systems the vehicle computer monitors. You should be able to cross the code to the charts in the maintenance manual, (I use Haynes supplemented by a subscription to All Data). This should point you in the necessary direction.
