#69 of 75 2012 highlander electrical issue
Jan 01, 2013 (4:40 am)
This is just a "heads up" for anyone who has or is planning to install a trailer hitch from u haul. Mine was installed in dec 2011. Three weeks ago my check engine light came on. Went to the dealer and the computer read out indicated a faulty neutral safety switch. The replaced the switch but it did not solve the problem. They had to contact Toyota technical support and get back to me. In the meantime 3 days ago I went to use my highlander. Put the key in -- nothing. Lights were working, etc but essentially it was dead. Finally was able to start it with the remote starter. Called a tow truck and brought to the dealer. Several warning lights were on. The dealer finally tracked the problem to the wiring harness installed by U haul which was short circuiting the electrical system and shutting things down. They removed the wiring harness and it is ok now. If you have a hitch installed by anyone make sure they use an isolation module with it. I never would have tied the problems I was having to a trailer hitch.

Oddly, this is a recurrent theme over many years for after market wiring for trailer electrics. Auto-electricians usually look at non standard wiring as their first point of tracing problems; the manufacturer's wiring loom is pretty fool-proof so you search for what is different about the vehicle.

On my 2012 HL there was an optional 'tow package' that was, as I recall, under $200 and well worthwhile for the heavy duty radiator, battery, etc. Small cost for a little extra margin of safety and reliability.
#73 of 75 Towing with 2007 Highlander questions

I have a 2007 Highlander that I have babied and pampered as much as I can. It has a tow package installed. I now have a new (to me) pop up tent trailer that weighs 2800 dry weight. I do not intend to load it very heavily and will not travel with water in the tanks. What advice do you folks have?

I tow with my 2007 Highlander Hybrid and am very pleased with it's capability. The Hybrid is rated for 3,500 lbs and can handle it easily. I just trailered my boat 500 plus miles through hilly country back roads and on the interstate hwy. always doing the speed limit and with the cruise control engaged she kept the speed up.
The Hybrid has the CVT so you don't feel shifting all you see is mpg dropping going up hill and getting better going down hill. I averaged 17.8 mpg which was a lot better than the 13.1 mpg I got with my Nissan on a similar trip.
Love the V-6 when getting up to speed on the hwy and love the hybrid for better mileage.
#75 of 75 Break controller problems
Jul 31, 2013 (11:13 am)
I tow an EggCamper with my 2013 Toyota Highlander. The Highlander came equipped with a dealer installed hitch and 4 point connector. The EggCamper has electric breaks, so I had a Curt break controller and a 7 point connector installed. My problem began shortly after installing the break controller. The system worked find and I was able to set -up the controller to my trailer so that the trailer breaks were activated properly when the Highlander breaks were activated. About a week after setting up the controller, while not towing, the Highlanders computer indicated an ABS Break malfunction. The Toyota Dealer checked the break system and stated that the installer wire the controller to the ABS load sensor and the controller should be rewired properly. The installer attached the controller to the "blue" wire on the break pedal. All indications are of the four wires on the break the "blue" wire is the proper wire for this connection. If I disconnect the controller wire from this connection the ABS Break malfunction goes away.
My question is has anyone had a similar problem and, if so, how was it solved.
