I traded in my "worn out" 2011 Tacoma TRD on a 2012 TRD T/X Pro as I could lower my payments and get an updated model. Here's the issue... this is the 4th 4L Tacoma I've owned ('06, '08, '11 & '12) and this one will kill the cruise control towing my empty trailer on the highway. Not even big mountain passes... forget those. Just interstate highway gentle hills. I also noticed that towing an 1800lb trailer to Des Moines a few weeks ago, it spent A LOT of time in 3rd gear on I-80. Maybe its more noticeable than the previous 4.0's because this has the cat back tuned exhaust which is loud, but I've towed that trailer thousands and thousands of miles with better mileage in 4th and 5th gear. The empty flatbed utility trailer is a tandem and probably weighs 1500, but on a hill... forget it... it not only wont hold speed, it kills the cruise. The previous versions might lose a few MPH, but not bad.
So, what's up with this? Anyone know if there's a flash override for this? I had it at the dealer (6500 miles now) and they say its fine. A friend tows a boat with his 2012 Tacoma TRD and has experience the same problem. I got rid of my Cummins BlueTec partly for this reason... its a pain in the butt when you're out on the highway long distance. Any ideas???
