I too am looking at the 4.6 to tow about 6500pounds. Has anyone actually used the 4.6 to tow a big load yet? I live in the mountains of BC and we have big long hills. I am thinking of the 5.7 but I will use the truck as a daily driver as well and getting a bit better gas mileage is important over the trucks life. If someone out there is towing 6500-7000 pounds with the 4.6 and is having no problems please let me know.

Kirsty – See the last comment Jeremy left here – http://www.tundraheadquarters......wer-quiet/ – definitely seems like there’s an electronic “ghost” Toyota is hunting. As I said before, this is a sensor problem that Toyota is still trying to lock-down…it might even be a software problem. As these vehicles get more complicated, finding the problems becomes harder.

Also just bought a 4.6L Tundra and have the same issue. Check engine light came on after about 300 miles. Took it back to dealer and they said that solenoids for valve actuators had to be replaced. They only replaced 2 of the 4( which I found out later) and called to say truck was ready. I picked it up, had it for 3 hours and the light came back on. The truck has been in the shop this time for almost 2 weeks. They are saying now that it is a sensor problem(maybe). I was told that they will be replacing the other 2 solenoids but those are on backorder and that they will be replacing the oil and filter. Traded in a 2006 Tacoma for this and now I wish I hadn’t. The additional power and size is great but I just don’t want to have endless problems with this new motor. I was actually told by the dealer that it is the same motor that is in the Lexus. Is he full of it?

This issue has come up on both the 2010 4.6 and the 2010 5.7. As near as I know, it’s a sensor problem…but no one has managed to explain it for sure.

Kevin – If you’re looking at the old 4.7, you’re in good shape. If you’re looking at the new 4.6, you’re in great shape…just keep in mind that wind resistance is the issue on a 27′ camper as well as a 6500lbs sailboat. The truck will pull just fine, but when you hit 65mph you might be dragging. The 5.7 is strong, but sometimes those really big, bulky loads are best pulled by a big diesel (despite their relatively low weight).

Kevin according to my 07 book a 4.7 can tow 8,000lbs. That’s total amount of weight in trailer and your load in the truck. The sailboat if empty is also good.

Wow,I wanna see that engine.It looks like an excellent addition to Toyota’s line up…I at first thought they would use the same 4.6L that the Lexus LS(380hp!!) has.But that in a car.And I agree with Steven Hitchcock,a 4.6 in the tacoma will be SICK!It would be the most powerful mid-size truck.The dakota has 302hp,but it’s junk…lol…

MK – It’s interesting to hear how different truck owners view certain features and options. Take the 6.5 foot bed on a crew cab – that’s a great feature for some people, but a lot of the “family” buyers won’t be able to fit a truck that long into their garage. That’s why Ford, Dodge, GM, and Toyota all offer 5.5 foot beds on the crews. The automatic 4wd is a good feature to some, but there are a lot of old-school truck owners who are irritated about the fact that they can’t manually engage the transfer case or the hubs. The rear locking differential is a benefit in a lot of situations, but Toyota’s system allows for more efficient and effective traction control. I’m with you on the tailgate and chrome, and I agree that Toyota needs to test extensively. I’m pretty sure that’s exactly what they do, why else would they be number 1? Thanks for commenting.
