Ringing noise that only stops when stopped 2024 LC

[cruisercruising]

I downloaded an app on my phone that records sounds. In the first picture towards the right there are no spikes. The second picture represents when I can hear the noise. It has spikes around 14,000 hz. I’m thinking this is why some people can’t hear it (the guy at the dealer said he couldn’t hear anything). I took it back to the dealership and rode in another LC. I couldn’t hear the noise in that one, so I know something is up with mine. This graph proves I’m not crazy!

My hearing cuts out around 10,000 hz so I wouldn’t be able to hear it but my wife or daughters would tell me I’m sure. Need to find a technician at the dealership less than 30 years old with good hearing so they can confirm to the dealership what you’re hearing.

Only 120 miles and I get a rattle/pinging sound when starting out (not at ideal) - when i rev the engine in neutral its there to0 - i think it’s comming from the exhaust system or under the vehicle but it seems to lessen as the vehicle gets warmer?

I'm glad somebody else can hear it. It's not the pedestrian warning noise. It's coming from under the car. I'm guessing it's something to do with the engine or transmission because the noise shuts off abruptly when stopped, which I think correlates with the auto start-stop feature. I'm taking it to the dealership tomorrow

Sorry for a noob question but I was wondering about your comment about the auto start-stop feature. Is that the one that shuts off the engine when you are stopped at a traffic light? Had that on an F150 and wasn't a fan

Then you will be doubly disappointed with the Land Cruiser. It’s a feature.required for the operation of the vehicle and cannot be turned off.

It's a hybrid, not a gas engine alone, so not the same as auto start/stop. A lot of people seem to be confused about that. The electric motor is always on, it starts the gas engine when needed.

^^Thanks for posting! Think I'll have to go for a test drive before I make a commitment on one of these. None around here from what I hear.

The sound in the second video reminds me of brake wear indicator squeal. Or, as someone mentioned, a small rock caught between the pads and the rotor. Both would coincide with the sound stopping when the wheels aren’t turning. I’d pull each wheel off and check for indicator clearance and any obvious wear rings in the rotor face that would indicate a rock is scratching the rotor. Just to be sure it’s not something simple like that. If it is indeed the electric motor sound, then bummer and a dealbreaker for anyone who can hear that I’d think. Sorry OP.

Just heard the same tea kettle noise in our LC FÉ today. 300 miles on her. Only does it sporadically.

So for the first time I've noticed just today after getting the car serviced it makes the tea kettle / tinnitus sound when driving at all times. When completely at a stop it also stops. Did anyone else figure out a solution?

 

[jmo]

Bump. Also just started noticing this Anyone here find solutions?

Nope, unfortunately not. I'm at 7,000 miles, still makes the noise. I guess I kind of have gotten used to it but I still hear it every single day

I can barely hear it, and the dealer states it is the regenerative braking charging the hybrid battery. It sounds more like a whine to me.

I noticed the sound this morning, not thrilled about it. Just hit 1,500 miles, and I’m confident it didn’t occur until now. I’m going to bring it to the dealer service center and see what they can do, even though it seems many of you have not had any luck :/

I had this checked out at the dealership last week. They ran their system checks and said everything was normal. They acknowledged the noise and theorized it was likely due to the electric portion of the drivetrain. They compared my vehicle with another unsold LC on the lot - also made the same noise. Not sure how there aren't more people complaining about this.

 

[thadiusmaximus]

High pitch sound in my 2025 Land Cruiser as well. 600kms on it now and noticed around the 300 mark and it drives me absolutely nuts. Completely triggering tinnitus. Talked to the service department and they could hear it and says it's normal with the hybrid motor but no way that can be normal. Something has to be done. Absolutely love the vehicle otherwise but starting to dread my purchase. Any help extremely appreciated.

Sounds like the same noise I’m hearing, I agree with the rest that it’s the hybrid tech doing its thing. Some times on the gas, some and most times when just coasting. I notice it transitions to that electric only mode quite a bit while in Eco mode. Maybe the drive mode plays a part in how often that happens, don’t know that. My wife has a Lexus ES300h and it has the same ring as the LC as far as I can tell.

Hi,

I just purchased a new 2024 LC trim yesterday. I noticed there is a constant ringing that ONLY goes away when I am stopped. As soon as I let off the brake and the car begins to move the ringing starts. It doesn't stop again until I am completely stopped. Any clue what this could be?

I know this is kind of old now, but OP, did you ever get anywhere with this? I'm having the same problem and I'm in the process of escalating this to great heights. I've been to several shops and service departments, have been told it's "normal" hybrid noise, yet the rental they gave me, a 2024 corolla hybrid, is dead quiet. So it isn't normal hybrid noise. They sat in the car with me and told me it sounded like the battery fan but then they changed their minds and said maybe they don't know what I'm talking about. It doesn't really matter if some people can't hear it, because if the 2024/other model hybrids are not making the noise, this needs to get onto their service bulletin so it can get fixed for all LC's.

I took mine in today for a full diagnostic, more in-depth than the typical maintenance checklist, and if they try to say it's normal when they're done, I'm just not going to accept that answer and I'll call corporate in the middle of the shop for all I care... They gave me a rental today, it's a 2024 corolla hybrid and it's extremely quiet. No ringing. So things are not adding up. I even took my LC to a car audio specialist yesterday and he got into the car and immediately said "there's something wrong with this car, that would drive me nuts" so we have to get this on their radar with the service department! It's not okay!
