Bought the truck brought home heard a knocking in engine brought back to dealership they said nothing wrong some knock and some dont they cant do anything. I kept the truck and still own it today It has 148000 miles on it and still knocks the same as when I bought it. If I were to try to sell it no one would buy it because of the knock. In November of 2024 I saw Toyota had a recall on 2022 and 2023 models because of an engine knock. So I called Toyota and asked them why didnt they recall the 2007 Model Tundra. They couldnt give me an answer like they didnt know there was a problem. I said its on record that I reported to Toyota my complaint and it is on record. Still I got no where.

Just purchased a clean one owner used '07 Tundra, my first Toyota. The "piston slap" issue is well documented on many sites, including Toyotanation.com, Tundranation, etc. There are more posts and threads than one person can read in a lifetime. I came out of an '01 Silverado with the LS platform engine, and it was still running flawlessly with 232,000 miles. It too had piston skirt knock when cold. Several of the same type trucks in our company fleet have done it since new. My son's '06 Lexus IS250 had the exact same problem when cold. GM seems to have gotten a handle on their problem. The new stuff is pretty quiet.

For being a supposed, "Quality leader", Toyata sure likes to dupe their customers with a lot of bullshit at the dealer level about those engine noises being "normal". If I wanted to listen to that much engine noise, I'd drive an old Ford PowerStroke, or better yet, an early muscsle car with Forged Pistons, because that's exactly what it sounds like. If it didn't have 380HP and a decent interior, there'd be a big FOR SALE sign in it tomorrow. Really too bad you can't buy anything worth a damn anymore, no matter how much you spend. This deserves a class action lawsuit from what I've read so far.

I just bought a 07 with 30,000 miles on it last week. The next day I heard the knock as I was pulling out of my driveway. It lasted the whole 2 hour drive to work. The knock is there at about 2000 to 3000 RPM. It sounds identical to a spun bearing I had with my Mustang. I immediately got online and found all of these posts about the knock and piston slap issues. The next day I took the truck back to the dealer and told them I wanted nothing to do with a truck that sounded like this. They told me not to worry that the service department would take care of it. A week later they had their master tech look at it and he told me that the sound was normal.

I have family and friends that drive Rams and Siverados and it's kind of embarrassing when they hear that noise and ask me what's up with it. I was a tech for years and piston slap was never something anyone I knew in the field would consider normal.

I called Toyota in CA and was assigned a case manager. The case manager called the dealer and was told by the dealer it was nothing to worry about. The case manager offered no assistance and according to her was not aware of any issue with the 5.7L. They basically said I was stuck with the truck and would have to put up with the noise.
