2000 Toyota 4RUNNER: check engine light

Filed Aug 14, 2015 · 75,843 miles · IL

The check engine light came on and we noticed that the vehicle was leaking fluid onto the garage floor. Took it to the toyota dealership, where they informed us that the frame of the vehicle was extremely rusty with a possible hole in the frame and unsafe to drive. The leak was from the transmission fluid. The component that houses the fluid was also rusting. The check engine light had no codes at this time. We took it to an auto repair shop in our town and looked at it up on the lift. The frame on the passenger side is so rusted it is cracked and there is a hole in the frame clear as day (dealership stated possible). They also replaced the oxygen sensor, due to the check engine light being on. We now have an unsafe vehicle on our hands that we can not drive, sell or even trade in!

Our 2000 toyota 4runner, on a recent road trip, had the engine light come on while we were in rural kansas. Upon having it towed to the nearest toyota dealership, we were told it had "engine sludge," and that we needed, at the least, a rebuild of our engine, and at most a new engine. The car has been well-maintained, and prior to this incident had run fine. Oil had been changed on a regular basis, and the vehicle had sufficient oil, and clean-looking oil, as it had always had.

I just purchased a 2000 toyota 4 runner with 80k .the check engine light gave a problem code of po171 mass air flow sensor .me and my kids went to grab supper at the dairy queen and had just pulled out of the dq when my car started shuting down in the road way, my 4runner could not exceed 25mph .almost a crash! From all ive seen on the internet this is the number 1 problem with the 2000 4runnner and could cause aserious acicdent or death. The car dealer replaced the mass air flow sensor for me at no charge. I think toyota knows there is fault in the mass air flow sensors I read online where one toyota dealer had sold over 300 new mass air flow sensors.please feel free to call me anytime.jsr7044775308

On several occasions I have take my car to the dealer trying to get my check engine light and car stalling repaired. On two occasions my car has stalled without any warning. The first time was when I was in the middle of making a left turn and the second time was when I was making a right turn. Also the check engine light goes on and off.

When I bought the vehicle the check engine light was on. Then when I got into the vehicle there were more miles on it then stated on the paper work I filled out. I took the vehicle back and forth to the dealership and they just reset the check engine light. One the way home from the dealership which is over 100 miles away, the light came back on. So I had a toyota specialist look at the vehicle and he hooked up a diagnostic machine to it and found the problem. I didn't take the vehicle back to the dealership just for the simple reason that they didn't know what they were doing and they were very unprofessional.

Car stalls on deceleration with check engine light (red). Toyota truck was taken to the dealership twice without a permanent resolution. Upon contacting manufacturer and in turn toyota service & repair they stated they are aware of the problem and that there is no resolution to the problem. Toyota service advised me to drive vehicle and not to completely fill gas tank, because if the gas tank is overfilled causes car to turn off. Due to gas getting into the vacuum system. *ph *nlm **dimsii ivoq entry posted after 12/12/02 cut over to artemis**767680
