Hello All:

I have a 2006 3.3 6 Cyl. Limited Highlander with about 189k miles. Late this last fall, my dash Engine Service light and VSC light came on. I took it to the dealer for diagnosis and they did a complete service check on the cars electrical system. Everything checked out good, except one area in the vehicle, they could not gain access to. They said that they could not get to the gas tank sensors and wiring. I think, some mice climbed up on top of the gas tank and started to nibble on the wiring. They said that they would have to disassemble all of the rear components and hardware of the highlander to drop the gas tank to check out the electrical connections and sensors . They said that the underbody of the vehicle has a lot of rust. I purchased the vehicle used. I know it was owned by 3 other owners who lived in upper New England. That area uses a lot of salt on the road ways during the winter season. The dealer is concerned that if they do the rear end disassembly, they may break bolts and connections, due to the rust. They mentioned, that I could continue to drive the car as-is with no problems, but I will not be able to get the vehicle to pass my states emission test, due to the Engine Service light and VCS light. I feel, my only option is to sell it or try to use it as a trade-in for another vehicle. I really like my Highlander and its body color. It’s loaded with everything I like. I would appreciate any suggestions for handling my dilemma. Thanks

What are the codes? What state?

Take the + off for 30 sec. and pull it back. If the lights go off, go and inspect the car fast. If not, trade in.

Thanks for the replies. The dealer did not give me the codes when they did the electrical inspection. Thanks for pointing out the 1A video. I also found a 1 video showing the fuel pump replacement via the inside car floor cover; under the rear seat. My dealer removed my vehicles rear seat, but there was no access cover to reach the fuel pump or wiring. So, the only way to reach the tank and wiring is to remove the rear exhaust system and drop the rear axle and drive train. Doing so, could break badly rusted bolts and mount supports. After seeing the video on how things should work, I’m not happy. I really like the 1st Gen. Highlanders. I guess I’m going to have to find another one. Thanks All

Keep in mind that the dealer is trying to scare you away. They can make more money working on late model cars. Your car represents risk. They may not be able to beat the book time due to rust. Get a second opinion from a good independent shop.

I wonder if you could get a endoscope up in that area to inspect it somehow. I did that on my prior vehicle.
