Hearing a rattle noise at low gear acceleration.

Hello everyone, how are you, my name is Angelo Semorile and I am writing to you from Lima-Peru.
I probably have the 1st LC here and bought the gasoline version with a NON-hybrid 2.4 turbo engine.
I have the same rattling sound basically when cold, between approximately 1500 and 2500rpm, so I can assure you that it is not a problem with the hybrid.
I have filed a complaint with my dealership and they tell me that they do hear the sound but that it is NOTHING, obviously I am not satisfied and I have requested an official communication and a report.
I will let you know that from what I have read, no one from TOYOTA has yet stated what the problem really is (let's rule out the hybrid).
greetings
Welcome to the forum Angelo!
 
Hi everyone,

Juste created an account here to say I have the same problem as you guys. 1958 trim built at the Hino plant. Fingers crossed that it’s not too bad. Going to my dealer this week to report my problem before changing my tire to 33´s so they can’t blame it on them. I’ll keep you posted.

I have an appointment next week at the local dealership as well. Will report back as well. We will get to bottom of it
 
took my LC in to toyota at 1000 miles for this same noise, they test drove it and drove a brand new one to compare they said noise similar, on inspection they found nothing wrong..... at least i know my new machine aint broke.

Thanks for reporting back. I am hoping the dealer doesn't tell me the same thing. I am willing to fix this myself, if I could find it. While I don't think it will affect anything internally, it is annoying. I honestly think it is a heat shield or some thing on the passenger side engine compartment by the firewall. I wish I could reproduce while on the ramps or on a lift. One of us will find it, and hopefully let everyone else know.
 
I have the LC250 LC trim and have the same rattle while cold.
It seems to be a drivetrain thing because the rattle is not present when revving in Neutral. Wondering if this is the case for everyone else.

3500 miles on ODO
 
I have the 2.8L diesel in South Africa and found as soon as you approach a stop sign or red traffic light and brake quite hard to stop, the engine revs drop quite low and for a second it feels the engine may die. A friend has noticed the same with their Prado. . This is my first diesel - is this normal
Hi there, first time here. Do you feel a vibration? I took delivery of my 2.8 diesel 2 weeks ago, and have been having the same issue. At first I thought it might be ABS related, but the rpm go a little low while vibration happens. Did you figure this out? Thanks.
 
Update. Took the dealer this morning. Was able to reproduce the sound with the Tech in the car. We could not reproduce while in park or neutral only under load while driving. The best way to reproduce the sound without going up a hill, is to hold the break @1500 rpm while driving 10-15mph. This will keep the load constant and rattle is very noticeable. This is the exact sound. You can keep this sound constant by holding the break.



The tech is going file a report directly back to Toyota. He said they had a similar issue with the new Sequoia and it was fixed with a software update.

I also open a case with Toyota.

They said it’s not a big issue and to keep driving and wait to see what Toyota says.

I am hopeful for a fix from Toyota and not having the local dealer tear apart things until they find the issue.

I think we all know first year cars sometimes have issues. Let’s hope this addressed by Toyota and fixed.

I would encourage everyone to report this at their 5k service appointment or when they go to the dealer/shop. Unfortunately, large companies like Toyota don’t really take things seriously until enough people complain.

If this is the only major issue I encounter, I will be still happy with the LC. Everything else besides some really minor items is good IMO for a first year car.

Thanks for the update. I’ll log a case with Toyota and also have my dealership try to recreate when I bring in for my next service.

Send the video above to the service advisor before the appointment and try to record it yourself. IMO dealerships these days are very good at replacing parts, but not putting in the work to actually fix the root cause. The service departments at most dealerships are just profit centers to generate revenue. They have very little motivation to find and fix this issue unless they get an exact reason from Toyota. Since this issue is becoming more common Toyota should issue a TSB and the dealerships will charge the labor/parts back to Toyota. From the previous comments on this thread, dealerships will say that can’t reproduce the sound and can’t hear it or it’s normal. I would show the tech directly with you in the car when you drop the car off (request this before the appointment)
 
I have the same sound, something drivetrain related I'm guessing. As mentioned above, doesn't do it if revved in neutral, sounds smooth as silk with no load. Have an oil change appointment this Saturday, I will mention it.
 
Someone on this forum posted about using shell gas and the noise for that person completely went away. So nothing to lose I have tried that. So far two fuel ups with shell 93 and I must say the noise is no longer as pronounced. Now it sounds more like just a noisy engine rather then something totally abnormal or something is loose.

I use Shell Nitro 93 and have the rattle
 
Plot thickens... I have it too. Has anyone tried lubing those zerks yet in the drivetrain then testing? I might try it

I have same exact issue- this is the best video of the issue - it’s hard for me to believe a software update could fix this but whatever the solution is I hope it comes fast- I’m gonna take mine in to local dealer. The temperature of the engine has to be in a specific range (wont happen when cold) to get the rattle most noticeable but I hear it every day and it’s very disturbing- can’t wait for it to get fixed- thanks for posting this.

I use 93 octane Ethanol Free fuel from a BP station, and still have the rattle.
 
I am at 6500 miles. I had the rattle for several thousand miles. I noticed the past few mornings the noise is not there. The only change I have made was a different gas station that I have been using for about a month (Chevron/Texaco) 93 octane. However, I am not sure it is because of the gas. The previous gas station was a Top Tier Certified Marathon.
