The parts that make up the 2007 Tundra 5.7 V8 engine and 6-speed transmission are made in America by American suppliers which explains the quality control glitches that occur from time to time. Corporate Toyota can't force us Americans to be change our cultural ways and become obsessive about maintaining consistent quality control the way their workers in Japan are.
One thing Toyota can and does do is design their engines and transmissions to be exceptionally inherently reliable and durable to begin with so that the vast majority of owners will have a satisfying ownership experience in the long run.
By contrast Ford - Chevy - Dodge don't design their engines and transmissions to be highly reliable and durable in the long run so even if they do catch assembly related glitches before the truck gets into the hands of a customer, in the long run their customera are going to be less satisfied because of engine and tranny failures several years later in the trucks' life.
The severity of the dissatisfaction depends on the customers expectations. Some domestic truck buyers think 150-200K miles of engine and transmission life is excellent, but as they begin hearing 300-500K durability testimonials from Tundra owners 5-10 years from now they will become envious.
I wonder how long it will take them to figure out which trucks could have the problem? I'm planning a trip in a few weeks and it sure would suck to breakdown hundreds of miles from home. Mine was built 01/07 in Indiana.
I recall that early in the launch that the Alabama engine plant was not fully geared up to make the 5.7, and that the initial 5.7's were supposed to have come from Japan. Just curious if these "problem engines" were US made (more likely) or from Japan. Maybe this was a problem with getting start with US production. Just curious.
US built Toyota vehicles and engine quality is lower then what manufactured in Japan. Unfortunately, if they keep on increasing their production here the quality of toyota vehicles will continue to fall. The quality of the assembly and domestically mfg parts quality is a lower when compared to their japanese counterparts.
I have a 2004 toyota corolla buitl at Nummi in California and the build quality is rather poor.
Mine seems to be the only one from Texas so far. Built in March.
Mine was built in Texas in January 2007. When you say the only one in Texas are you referring to the fact you have had trouble with your engine also?
Where did 5.7L engines come from before Huntsville, Alabama began delivering production engines? And what was the transition date from pre to post-Huntsville engines?

No, no trouble whatsoever. Except I have 5000 miles on it already.
Can someone explain what happens when a camshaft fails? Does it just stop? Does it explode, or create a loud noise? Will it continue running?
Also, how does one fix it? I'm assuming it's a complete tear-down of the engine, which I suppose is why Toyota thus far has opted to replace the engines instead of fixing the old ones.
Also, does a camshaft breaking cause other internal damage to the engine? I would think that's a real possibility.

This is your opinion, not fact. There is without a doubt a trend on this forum to bash anything American. Just because it's not Toyota or it's not made in Japan doesn't mean it is total crap. You are contradicting yourself by claiming that Toyota designs their product for the long haul, yet they decide to use cheap, poorly made US parts to build their products? It can't be both ways. According to you, Toyota starts with a brilliant idea, uses crap to build it, and ends up with the best vehicle on the road. Sorry, it doesn't work like that.
Furthermore, how did you come to your conclusion that domestic manufacturers don't design their products to last long? Where are all these Tundras and Tacomas with 300k-500k miles? They have been out plenty long enough but I have not seen any. I'm sure there are some out there, but they are the exception, not the norm.
If you want to see the real high mileage vehicles that are used for severe duty, look no further than the domestic 3/4 and 1 ton offerings. There is a lady in my neighborhood that has an 04 Dodge diesel that she uses to haul horses from KY to NY and FL for a living. It has 456k miles on it and just recently had to have the head gasket replaced. I seriously doubt there will be many Tundras used in such a fashion that will see those kind of miles without some major issues along the way.
Not to bring up the Toyota vs. Domestics again but there is so much BS that flies around here from people who have no clue what they are talking about sometimes so someone needs to inject some reality. The Tundra is an awesome truck, but it's not going to rack up half a million miles with ease. If it's made by man, it will have flaws, even if the men that make it are Japanese.
