#1964 of 2007 2007 Toyota Tundra Engine Noise
Nov 25, 2009 (8:46 am)
I am approaching 40,000 miles on the 5.7 liter engine. At start up it sounds like a diesel and has always done this. However, at full operating temprature it makes sounds like the valves are knocking or like low octane gas. I have run 93 octane gas and this does not help. Going up hills seem to make it a lot more noticeable or when the engine has a load on it. Took to the dealer and the service manager and I drove the truck around and he says it is the exhaust resonator at the back of the engine doing this. However at first they told me it was the variable valve timeing doing this on a previous visit. Has anyone out there heard this BS from any Toyota dealers? Everyone at Toyota seems to think this is normal.

I have a 2009 Tundra 5.7L with 5000 miles on the engine. The truck has been to the dealer 4 times for the engine KNOCKING noise, the noise I have is not piston slap, I've owned 3 GM trucks prior to buying the Tundra and I know what piston slap sound like. My issue is different from the issues most of you are reporting. The engine KNOCKING noise in my engine occurres after warm up and at operating temp, the noise comes and goes and is not constant. At 4800 miles the dealer (at the direction of the factory rep) replaced all the hydraulic lifters in Bank 1, after driving the truck for 20 miles, the KNOCKING noise was still present.
I took the truck back to the dealer on 112809, got a call back from my service department, there were 3 factory reps at the dealer with my truck, at the direction of the 3 factory reps, they told the dealer to pull the motor out of the truck and tear the motor apart. The factory reps will return to the dealer on 120409 to look at the torn down motor to see what the problem is.
I contacted TMC and filed a case when this issue started a few months ago. I'm not here to bash toyota because I love this truck, but Toyota has the WORST customer service I have ever experienced! To all that have this engine noise, I recommend you stay on Toyota and file a case with TMC and be PERSISTANT.

I've had my tundra a year and a half and in my 30+ years of owning trucks, cars I've never owned a vehicle with as silky smooth power train as this tundra. Sometimes I believe it must be a high end Lexus and not this big huge truck I'm driving in. No wonder Toyota's resale value is so high.

Did you not read what I wrote? Just what I wrote.............THAT IS WHAT THE HELL I AM TALKING ABOUT! AND I DON'T WORK FOR FORD OR CHEVROLET OR DODGE EITHER! I ACTUALLY OWN ONE AND IT KNOCKS AND PINGS AND I AM PISSED OFF TOO!
Also I own a 2007 Tacoma and it is "SILKY SMOOTH" as you say so I may just trade it (TUNDRA) for another Tacoma or a 4-Runner. I don't hate Toyota! Just telling you what my truck is doing...........

have picked up the same dash rattle you described, passenger side, in the dash, is the most noticable in cold weather. was wondering if your issue was resolved (your post from a few months ago) or if others have had it and any luck diagnosing...

No! I traded the truck for a 2009 Toyota 4 Runner and I am very happy with it! Also, my truck did not have a "DASH RATTLE" as you say yours has. It was something in the engine on mine. Well, I am done with that problem! I recommend anyone buying a new Tundra to get any engine but the 5.7 liter! They need to do some more research on that engine! Or, just make it a diesel because mine sounded like one anyway!

my "rattle" more like a squeek, try having someone open the door and see if it stops....

Wyoreb...Just this past week I noticed an occasional "rattle" coming from the RF corner of the dash/windshield area. It started after we started getting really frigid temps, and doesn't do it every morning, and then only for less than a minute as I'm driving over uneven pavement areas. What I visually noticed as new was the plastic panel that runs across the width of the dash and butts-up to the windshield, the right front corner has dropped about 1/4 inch, and down from what I can see is a thin raised rib at the bottom of the right A post plastic trim cover.
I'm not sure what's going on here, but I'll be calling my service writer at the local dealership in the next week or so to see if he knows anything about, if there's a TSB as seems to be mentioned in a previous post, and what they can do about it. I'll post the result, Regards, BGood

BGood, what you describe about the dash panel and the fit to the right front corner is exactly the same as on mine. Certainly didn't notice it at purchase, but it doesn't look correct (or poor fit/finish), and if it is missing some spacers or cushioning, it could certainly be causing this click-like rattle. Mine has rattled for several weeks, started out intermittant, but now is regular, especially at slow speeds and driving over uneven surfaces. I am going to get it checked out as well; we'll compare notes.
