Until recently I was very happy with my 2009 Toyota HiLux SR-5, it looked good and was great to drive, but then a mate told me that the transmission temperature light in his similar vehicle came on when towing his caravan. Three weeks ago I went on holidays with my caravan and, sure enough, my transmission light came on as well. These vehicles are quoted as having a towing capacity of 2200 to 2500kg, which makes me ask why they have an issue when my van weighs approximately 1700 kg. Adding to my concern two other owners have told me that this is a common problem with the HiLux. I have contacted Toyota and the dealer, but Toyota has chosen to disregard the issue saying they haven't had any problems. The dealer, however, admitted that there had been "some complaints" and said Toyota won't fix the problem until they have a certain number of complaints. Has anybody else had this problem?
We asked Toyota to look into your case and, while they haven't yet reported back to us, they told us they would investigate it. In the meantime to solve your problem it would be best to fit a transmission oil cooler.
