I took it to a nearby dealership and they found a Toyota Service Bulletin (TSB) on this problem with the 5.7 L V8. They couldn't fix it there so I took it to the dealership I bought it from (I was 300 miles from home when the VHS/ABS/LSD system failed) and after a day, said they would have to consult with Toyota.
The system failed 4 days after I bought the truck and I feel uncomfortable using it until it is fixed. Are there any others out there with this problem? I hate to think my truck is a lemon, but Toyota has given me a sour taste.
The truck is a 5.7L 2WD Reg Cab LB SR5 trim.
Another problem is fuel mileage. Highway mileage is 16.5 L/100km, vs the claimed mileage of 10.9 L/100km, 60% worse than claimed. I can see 5 or 10% worse mileage during the break-in period, but this is much more than expected.
Thanks

On my way to the shop last week the windshield picked up a stone chip. The windshield seems 'way too fragile to me. Has anyone had problems with windshields cracking on the 2007 Tundra?
Two things that are concerning me however have been the low fuel economy and a noticeable hum while driving. I've been avg ~14 us mpg with mostly city driving, about 70/30 cty/hwy. My driving style is very conservative for I've made a point of not gunning it from stop lights or hard acceleration on the hwy (cruising at 60-65 mph). A lot of people talk about the break in period an fuel economy should improve but there is much disagreement on how long that is. I realize this truck is a beast and not a prius, but my figures are consistently lower than a lot of the posts here. I hope it improves soon.
2nd point is the humm. I've read a lot about the torque converter and rumble strip issue, but it is only a sound, not a vibration. It doesnt happen all the time and I've tried to notice if it hapen when the tranny changes gears but haven't seen any pattern. I'd like to think I'm not being paranoid, that its a big engine and its going to have sounds different from those half its size. The biggest engine I've had prior to this was the 4.8 on my 2001 sierra 1500, which was almost silent.
Other than these minor gripes, I love this truck and would still buy it again in a heartbeat! ">
Take your truck to the dealership. Make sure each time you take it in, that they write up a repair order, report the problem 3 times. If they have not resolved the problem in 3 visits, you then may be elegible for a lemon law case.
No problems with the 5.7 motor at all though. It is noisy when cold, but if i let it warm up for a minute or two its fine, even when its in the teens. (mobil-1 0w does quite it down more)
I have 39K on it now and just noticed a wierd noise and feel coming from the front end. When driving around 30-35 mph on a slightly curvy road, i can hear a humming noise and feel some kind of grinding coming through the steering wheel. It almost feels like the front axle is binding up, as if i had it in 4wd on dry pavement and tried to turn hard (which i've never done in this truck). It really has me concerned now because i'm over 36K w/o an extended warranty. (i love that feeling)
Has anyone had an issue with the front end in the 4x4 models? My truck is driven 70/30 highway/city...
Sitting at a stop light, the engine revs from 5-600 rpm to 7-900 rpms. It fights against the brakes. Also, when coasting at about 1000 rpm and coming down, the vehicle will lunge up to 1200-1400 rpm. THis has happened 3 different days, I have 6,000 miles on it.
First, your A/C might be cycling on and off, which may slightly raise the idle to compensate. Both of my cars idle slightly higher when the A/C compressor is on.
Second, many vehicles have grade logic and shift to a higher gear when you tap the brake and are slowing down. Even if it doesn't, the RPMs are going to rise slightly when the vehicle shifts as it slows.
This behavior could be entirely normal.

Right now my truck is getting a new engine in it for a knock. The truck I am driving is a 4.7 Ltr and it is smooth as a baby's butt...if I didn't need the 5.7 to pull my camper I would be very upset when comparing the two engines. Trust me though, the 4.7 cannot compare to the 5.7 in horsepower.
I have seen many reports of this noise, and have a couple of friends that have these and say they have no noise. I guess I will have to wait and see, but want to take it in a few times in case it does create an issue down the road, I will have some recourse (hopefully). I told my dealer (American in Albuquerque) that some were reporting problems and they kind of shrugged it off. I would like to point them to a dearler that is actually pulling an engine due to the problem.
Where are you and what dealer has your truck?
Thanks
contact me at wingnutfe@yahoo.com and I will give you all my data.

Within 2 weeks, I went back to the dealer because the torgue converter wasn't downshifting cleanly. The tranny vibration was like going over a rumble strip. The technicians at the dealer didn't notice the vibration. I insisted they hook up their laptop to the diagnostic port and we went for a drive. After replicating the problem on multiple issues, the dealer agreed and subsequently replaced the transmission and torgue converter. Today, the transmission slips (hot or cold) when driving up my 22 degree driveway.
When I purchased the truck, I had a 5 state sales territory. I have experienced the roads of Colorado to California. On the older Southern California freeways, the expansion joints caused the rear end of the truck to bounce almost uncontrollably. A couple of times I thought I hurt my back. Outside of So. Cal, the bed bounce has been a non-issue.
I seen various messages regarding the knocking noise coming from a cold engine in the morning. I have the same issue. The sound reminds me of the "piston slap" I experienced from my 1965 Mustang with 200K miles on it. After the engine warms up, the piston slap noise goes away, just as my Mustang did 30 years old. This isn't normal.
If the issues above persist or get worse, I'll take it back to the dealer and have it fixed.
Other than the comments above, I don't think I couldn't have bought a better truck.
I commend Toyota for taking care of the problem...as I have stated many times I would still be fighting with Ford/Chevy and would still be trying to get Dodge to acknowledge that there was even a problem.
Toyota may have a few issues with the introduction of their new truck but making it right is what they are doing right. They have earned themselves one more loyal Toyota customer! In a couple of years when my wife is ready to get out of her Impala we will be shopping for a Toyota if they have kept up the good work.

5.7 L V8 2x4 Bought in March '07
Currently at 48,762 miles on my truck
But Gas Mileage is dropping!!!!!
My current Average mileage is listed at 15.6 MPG
worst in March so far has been 11.2, while my best
has only been 19.4 (not even 20 MPG), I don't know
why but November-January I was averaging between 16.5 and 21 MPG!!
And know in March I'm not even getting 20!!!
I go to all the services and I keep my truck in pretty well
shape!!
Anybody else having some problems like me? :confuse:
Please reply Back!!
The rumors I have been hearing is not much in the way of changes till 2010-2011. The rumors also consist of a 1 ton diesel, dual wheeled truck. Given Toyota's 4 to 5 year cycle for model changes I don't think we'll see much till 2012 styling-wise.
I would not sweat it over this "knock" issue. I own new Tundra myself and have several friends and relatives with the same 5.7 liter V8. None of which have had any issues with their new Tundras. Knowing Toyota and how they operate, if there is a problem, it's been addressed. Take the advice from the other poster and drive the vehicle you intend to purchase. Getting the VIN early will not tell you much as a consumer. Your local dealer should have the full VIN prior to it hitting their lot if you would like to have that. If you are ordering the truck special your local dealer should be able to tell you by their inventory sheet some sort of estimated production week and an ETA on it's arrival to their dealership. Toyota is real good about quality control and keeping track of what's happening and when.
I am positive if there is this "knock" issue that measures have been in place to remedy it. This 1st I've heard of it was scanning through these forum messages. No one that I talk to with a '07 or '08 Tundra w/ the 5.7 liter have had or heard of this "problem".
