Driving slowly with only the electric motor running my 2023 UX250h makes a kinda dry rubbing sound. Inside the car with windows closed it's hardly noticeable but friends standing outside have commented on the noise. I'm not particularly concerned and was intending leaving it until it's first service in July but wondered if others have noticed a similar noise? Is it perhaps an intentional noise to warn pedestrians?

hey everyone, Just swapped out the factory turanza er33s for a set of premium contact 6 tires and I noticed a humming noise between certain speed intervals (40-70kph). It sounds as if a wheel bearing is off, but it doesn't change pitch nor does it change when swerving from one direction to another which I've been told should happen due to unloading the faulty wheel. Only thing that does seem to change how loud it is is pavement changes and increasing the speed, though as mentioned, I can't seem to notice it at around 70+ kph. Can't seem to notice vibrations either. It's also only on 79000kms so I'd reckon a wheel bearing going out this early isn't probable (though I am aware of earlier failures). Some forums mention a period required for the tires to settle, but I've already driven some 200km on them in the last 3 weeks and they don't seem to have quieted down. I've played around with tire pressures, all the way from 2.5 (advertised for the fsport rims) to 2.3 and didn't notice any improvements. I'll be taking it to the shop I bought them from to have a tech's opinion on this, but I'm curious if others have faced similar issues. Comfort is well improved over the previous turanzas, but the noise gets annoying, especially since most of my driving is in town where I can't just gun it to 100kph to avoid the racket. The noise is quite similar to what this guy experienced. Will report back with findings.

Hi I own a 2015 f sport and love the car but one decrepency is the ride comfort, iv noticed it to have a very hard ride that can feel everything as well as very very noisey in the back with road Tyre noise, it has 18 inch Bridgestone tyers atm but also though of buying some nice 17 inch after markets and downsizing and changing to a softer more noise focused tyre, anyone got experience with f sport switching from 18 down to 17 and how it effected the ride comfort thanks

I've had my 2014 IS300h F-Sport which I bought on 37k miles for 2 years. From 3 weeks into ownership I noticed a squealing/squeaking at low speeds and when braking. Its quite noticeable even when windows are up. As the car was in warranty I took it to my local Lexus dealership. They said that it needed new pads and discs (almost £600). these were changed at the cost of the Lexus I bought the car from as my local dealership said it wouldn't pass MOT as it was. Not long after (within a week) heard the noise again. I too the car back again when my service was due and mentioned it was still happening. They checked at service and said nothing visually wrong so couldn't do anything about it but it had been checked. Plus they said they couldn't hear anything. The noise persisted and I took it back again. This time the guy who deals with me said he'd see if there was anywhere they could grease (as someone had suggested this to me when I posted the issue in here). Again they couldn't hear anything. They gave the car back but again the noise re-appeared. Gradually it feel like the noise was getting worse. Louder and more persistent (as sometimes you don't hear it). It also seems to be more apparent after a left turn and when coming to a full stop but not immediately after starting to drive, but after 10-15 minutes when things warm up. Also seems worse in summer. I contacted Toyota customer services as I am really at my wits end with this after almost 2 years of loud squealing/squeaking EVERY time the car is driven. As it was during our last lockdown they said as soon as able take it back to the dealership and they will have a look at it. I took it in this week as my service was also due and as I drove into the car park there it was loud and clear. Unluckily for me there was nobody there to hear it. I then asked the rep I was seeing to stand in the car park and listen. Moved the car back and forth no sound. Applied the brake no sound. So I asked him to wait while I went around the block to 'warm it up'. When I returned the sound was there again but he had gone inside as they were busy! I got him back out and asked him to go around with me - masks on windows wide open. We drove around the block in perfect silence - no noise AT ALL! I was so frustrated until we finally turned into the car park and there it was loud as ever before I even applied the brake and squealing even more as it came to a stop. He said "ooh that doesn't sound right". Finally! I told him I've had to put up with that for 2 years, every day. Even my wife is irritated by it and she doesn't get irritated, she married me! They had the car from Monday to Friday and changed the passenger side caliper. But apparently, this reduced the noise only so they changed the other one too. I paid for the extended warranty so this went through that. My wife picked up the car on Friday as I was unwell and they said to her the problem should be solved. After having it back 3 times and suffering the disappointment of it coming back I didn't hold my breath. Lo and behold, my wife took the kids out this morning and there was the noise again! I don't know what to do anymore and I am seriously contemplating cutting my losses and trading the car in somewhere which will lose me a good chunk of the £17k I paid for it. I will of course contact Lexus again but don't know how much more they will do (they quoted the caliper change at £500 each). If anybody has any advice or has had the same issue and solved it somehow please let me know. I'm not mechanically minded so can't take off and clean anything - and to be honest I shouldn't have to as I have had far cheaper cars with no issues whatsoever. I thought I was trading up! Any help would ne appreciated! Cheers

A few hours ago I had to brake fairly sharp to a standstill on a country road. Nothing major. No skid, no anti lock brakes triggering. Went to pull away and engine kicks in but sounded awful. Seemed to lack power and there was a clunking noise. I've pulled up and called Lexis assist. AA turn up 90 minutes later and I asked him how much he knew about these cars. He said he never sees them as they don't break down. He replicated the fault and greed with me it seems to be transmission. Awful vibration with engine running. Just waiting for a flatbed to put the car in overnight storage and delivery to Lexus in the morning. Another 90 minute wait. I explained to the dealers I scoured the internet to identify a car that was reliable and great on fuel, nice looking and nice to drive. With a great dealer network. Everything pointed to the Lexus CT. So this is massively disappointing.

Morning All, When stationary and drive is engaged with my foot on the brake pedal, if I turn the steering wheel I get a load groaning / creaking noise. I figure it's the brakes as if I put the car in park or neutral with the brakes released it doesn't happen. As a side note when travelling at low speed in a carpark for instance or approaching a junction to stop, the brakes do sound rough. So just wondering if this is a trait of the CT due to the mechanical brakes not getting used too often? Not so bothered about the brakes sounding rough at low speeds, but the groaning / creaking when parking the car is quite annoying. Like I say it's only with the brake pedal applied. Cheers.

Hi All, Hoping someone can help with an issue that’s what really irritating me. I’ve had my IS300h 2014 F-Sport for just over 3 weeks now. But I’ve noticed a squeak from the wheels at low speeds - probably up to 25 mph. If I had to say I’d say it’s louder when turning left. I’ve booked the car in to have it looked at for this problem and another but dealership can’t get to it until mid October. As I got it from a Lexus dealership I have the year’s warranty. I've seen a few posts on this in here but no resolution as the original poster doesn’t come back to say if it was ever sorted or how that was done. Understandable as we’re all busy I guess. Anyhow, anyone else had this issue and found a resolution? Paid a lot for the car so a bit disappointed by this and a few other niggles but hopefully just teething problems. Any help would be appreciated. Thanks

I've been driving my '18 IS300h for almost 3 months now and it's been an absolute pleasure so far. The only thing that bothers me is the noise level coming from the batteries' cooling fan next to the right hand side back seat. Usually this is not a problem for me though as I have the radio on most of the time, but if you have other people in the car it's quite embarrassing for a new car in this price range tbh. Of course it's not on all the time, but quite regularly though. Probably the dealer will say the noise level is normal, but I'm just curious about anybody else's experience on this? Wy does the fan need to cause a whistling sound? The HVAC blower fan doesn't whistle, so why does this cooling fan need to?

Grateful for your thoughts on this start-up noise. Persists for about 20 secs from when the engine kicks in at start-up and cedes thereafter. Probably worth booking it in, but thought I'll check here first to see if anyone else has experienced s'thing similar (or whether this is 'normal'). Thanks in advance, Friso IMG_1090.MOV

Hi guys great forum you have here! I have had a search and not found anything concrete about my issue. So I am going to post. If there is a post already I do apologise and feel free to point me in the right direction. My problem: I have a 2008 RX400h which i love. I have had it over one year now and it doesn't miss a beat. There is however a whirring noise coming from either the drivers front or rear wheel. It appears at random times and doesn't always stay for long. Sometimes however it can be on for a while. Sort of a whirring/light groaning noise but its not constantly on. I have tried to wind the window down however it doesn't seem to make it any easier to hear. I was wondering if it was a wheel baring but I have no idea how to check and it doesnt seem to get any worse etc so not sure if its something todo with the hybrid drive. Any ideas would be greatly received. Thanks in advance. Matthew

Hi! I have a late 2010 IS220D F Sport which comes with electric seat adjustments. The passenger side works as it should and is very quiet. The driver's seat also works well, but when I slide it backwards it is quite noisy - not a squeal but the motor sounds a lot relative to all other movements. The forward movement is very quiet, and I believe its the same motor working in the opposite direction. Any suggestions?

Hi guys Just started my LS400 MK4 1999 and it now makes an extremely loud whining noise. This occurred quite randomly as it was not making noise the other day. Any ideas what it could be? The noise gets worse as the RPMs increase and the pitch gets higher. Power steering seems to be working fine and have not had battery issues as of yet.

I have a noise which is difficult to identify , believe it might be to do with power steering as seems more prevalent when turning but can only hear when roof is down and then difficult to separate from road noise. There is a posting on you tube with very similar sound but no suggestion as to how it was cured , old post and for USA Anyone any idea , Lexus dealer could not hear it but only tested with roof up

Time ago I began to feel my car vibrating, especially at low revs. Driving another car with same engine confirmed this, older IS 300h was much quieter. I've noticed my car's engine start up is much harder than before, it feels like there is some resistance. Usually i drive only in urban areas, speeds below 100km/h. Today i drove on a highway and it was really problem to keep 130 km/h. My car for sure has lost a lot of power, or there really is some part making serious resistance in the drivetrain.

Hi folks, this is my first post here as I have only owned my CT200H Advance for 3 days! I'm running a 2014 model and notice that when I drive it on motorways, a lot of noise and rumble is being picked up from the road surface. When it drives over a bridge or recently repaired area, the sound changes or fades but never goes away. It is loud enough that I have to boost the radio volume to get a reasonable listening level. The noise starts to become noticeable at speeds over about 50mph and is pretty annoying. It certainly not the smooth elegant silence I would have expected from a luxury brand such as Lexus! I checked with my supplier (the excellent Lexus Cambridge) who advised me that the low profile tyres may pick up more noise than standard tyres. So I wondering, if I were to replace the tyres with standard profile ones, would this reduce the road noise? and can I safely do this without causing any other problems? Also, does anyone offer soundproofing kits that would help reduce noise pickup from the road? Another thing - has anyone else noticed - that the faster you drive, the less 'stereo' seems to come out of the radio/CD player. When its parked you can clearly hear sounds out of the left and right speakers. But when it is driving along, the sound appears to mainly come from the centre speaker and any left/right stereo signal seems to disappear. Most annoying, and again not what I would expect from a luxury vehicle (it is the standard system, not the enhanced Premier system). All the best from Cambridge, UK Paul

Just listen. If don't hear anything, put volume to max.

Recently purchased a used (2013) IS300H. Really enjoying my first Lexus and the IS300H is a pleasure to drive. The car is generally very quiet. However, I am a little concerned about a 'howling' sort of sound coming from the rear of the car. This is most noticeable when travelling above approx 40/50mph. The sound doesn't sound like a tyre noise, diff whine or failed wheel bearing noise. As I haven't driven another IS300H, I'm not sure if this noise is 'standard'. Any advice?

Hi After owning a 2010 60kmiles GS450 for three months started to notice the engine sound and Electric motor whining. I actually thought the car is dead silent and cannot hear a thing from inside but it is not at all true (at lease in my case). On a cold morning the Engine fires up to a rattles louder than normal noise. Like a Diesel engine. And i also clearly notice the whining noise of the electric motor. Is it just me or am i used to the silence that i hear such noises? Do you notice similar noises? Do you think I having a problem? Looks like i cant really show of to my mates how silent the car is. Thanks Hari

Ive got a '03 IS200 Sport and its only my second day driving her but ive got a previously un-noticed noise when I brake. From pretty much any speed as I slow down and it drops past 25-20mph theres a banging noise from the drivers side front wheel (or that's where it sounds like anyway). Its always at that speed and it does it 9/10 times when slowing down. harsh braking or soft braking makes no difference. ive replaced both front bottom ball joints and track rod ends and theres no play in the top ball joints. Anyone with any experience of this or any pointers of where I can look? Thanks in advance.

Hello everybody! I am driving GS300H for about a month and i am very satisfied with it. This is not a real issue but i think it is interesting. I had many cars before this and all of them were much louder after cold start. Warmed up engines were always quieter. Now it is different. When I'm driving using power from cold ICE, car is extremely smooth. It feels like as smooth as 6 or maybe 8 cylinder engine. There are 100% no vibrations and only barely noticable engine whistle. Maybe You laugh but comparing to my previous turbo I4 it feels so nice. But... When ICE warms up, it's more like ordinary 4 cylinder, especially at low revs. It is not bad, but when ICE is cold, it is much nicer. Did You realized it too?

Ok so basically had my IS200 for about 6-7 months and no problems. Just got back from a 500 mile round trip (mostly motorway driving) and now my once dead quiet gearbox is whining like there's no tomorrow. The only gear that doesn't whine is 5th for some reason. I've been through the forum and can't find anything like what I'm experiencing, as in where the car has been fine and then suddenly developed the problem. I've replaced the transmission oil but that hasn't solved it. Any help would be greatly appreciated :)

Dear experts, Any thoughts would be appreciated... When breaking at low speed, I can sometimes hear a pulsating, grinding noise, which slows as I slow - when breaking. About 3 months ago I had a seized rear calliper replaced (under warranty) on one side. I'm wondering if it might be the case on the other side, or something else? i'll have to take it into Lexus I think, but am still wondering what it could be. Has anyone else heard similar grinding (on,off,on,off ... ) type brake related noises? Regards.

Hi guys, I'm a newbie to this forum but have owned a Lexus for 5 years now. I had a 57 plate is220D for 5 years without even having to change a light bulb and have recently bought a 4 year old is250C, which is a beaut! Unfortunately The heater has just packed up and it's very cold out! First noticed it last week; it didn't work, then it did, now it's gone again? I read a post that it could be coolant level, I checked it and it was low. I topped it up and still no joy. Thanks

Hi. some time with my engine emits the sound of this IS300 from the movie ... sounds like a diesel... I've tried different oils, also checked the valve clearance and are OK. I have no strength ... someone met with something similar and solved the problem? thank you in advance for your help.

I have posted this potential defect description on the "rattles" topic, but I think it's a good idea to start a new topic. The problem is as follows: Just a few days after I've changed my tires for winter ones, I found strange sound and intensive vibration when I'm cruising with a constant speed, about 90 kmph and when an engine is running low, on about 1200-1400 rmps. I don't know, why this effect wasn't appearing on the summer tires. Before changing tires, I met some guy with his IS300h, and he was telling me, that car is great, but when he changed tires to winter ones, the car drives completely different, that he feels like riding on a bad made tarmac. When I meet him, I was on summer tires, so it was clear to me that he has got bad tires, but I have now different tires than he had, and I have the same vibration. Update: On this Saturday I was in the Lexus Service and the service mechanic heard and feels this sound and vibration from the first seconds. Then we checked other IS 300h ("demo car") from the salon on another winter tires. Definitely,the same vibrations and sound are present, happens on the same speed and rpms. My service center wants to check if there are any other records of this issue on Toyota. I'll inform you about any update. Dominik.
