Lexus LS 2007+ :: 600HL - Clanking Sound On Cold Startup
Jan 6, 2016
I recently got a 600. On cold startups there are times when it makes a horrible clanking sound when it does its ~2 second low idle. The instant it goes to high idle the sound goes away. After the car has been run, I don't hear the sound again until the next cold start.
This is not normal injector click, and if it is valve click there must be a side issue causing it. Like an oil primer working intermittently or something.

Last spring i purchased an 08 600hl. This is my first winter with this car and I have come across an issue. when it is extremely cold like it has been for the past few days the heating system for the interior of the car does not seem to be working properly. when i warm up the car and put on the heat it blows cold air. It is only when I am driving that the heat comes on. While i am driving at a moderate speed the heat works fine. However, when i drive slow, such as driving around a parking lot and its only running on hybrid battery power, it starts to blow cold air again. When i put the car in park and its only running off the battery i only blows cold air even on the "HI" temperature. I have the rev the engine to get the heat to kick in and then it will stay on. This is and issue or a normal behavior for this car.

I recently bought a 2011 460 L, CPO with 28,350 miles. I love the looks and how it drives, smooth! But I do have a concern. Before I go to the dealer I thought I would educate myself from the experienced LS owners. I am hearing a very brief (1-2 seconds) mild engine knock at a cold startup.
This only occurs when the engine is cold and has sat overnight. It never happens after this first startup, even after turning the engine off and then on again. It kinda sounds like the oil isn't getting where it should be for a few seconds. Engine sounds great with normal and hard acceleration throughout the day. The dealership where I bought it is 300 miles away, so I would be taking it to a local dealership.
Now I did hear this noise and mentioned it to the service manager when I first bought the car, and the service manager told me that this cold startup sound is normal. He also mentioned the direct injectors at idle. I guess sometimes it's hard to fully trust what dealerships say. Is he right?

Our 2007 RX350 with 91,000 miles started an annoying rattle at startup that lasts a couple seconds then goes away. The car drives fine and makes no unusual noise after the initial start. Its definitely not normal as it hasn't done it the last 91K miles we have driven the car.

I'm having 06 GS300. Just got the car about 2 months ago with 108,000k / 1 owner and she rides like a champ and I love this car! I want to do some preventive maintenance on her so she can keep me riding in style for years to come. The few things that I have noticed are as follows.....
1. Clanking sound in front end suspension when I roll over small bumps. It does not happen all the time, but it is noticeable. Almost sounds like a loose center cap on a set of rims. That's the sound I liken it to. Sounds like two pieces of metal hitting together. I was thinking some bushings maybe.
2. Squeaking coming from my front drivers side when turning the wheel while backing out of driveway or driving into driveway and when negotiating changes in the road while driving. Not very loud.
3. Suspension seems a little flat and I feel as though the struts and shocks need to be replaced. I'm wanting to lower it to fill the wheel wells and add a set on 20' rims offset 9.5 on front 10 on the back.

I have recently bought a 2007 ES350 that's runs fantastic considering I bought it with high miles from the Lexus dealer (149k). I live in warm climate area and I notice that even though it's not cold out in the mornings my car idles high (at about 2k) for only a few minutes 2-4 tops then starts to drop to normal as it warms up. It hurts me to hear it as I'm not use to this and I worry that it may cause damage to my engine due to oil not being circulated properly yet.
Most importantly, ONLY when cold, I hear a very light knocking sound, kinda like a bad lifter tick, but by the time I get to my daughters school which is about 5-6 miles away it goes away and sounds normal at that point. Had me very concerned as I just bought it less than a few weeks ago and I'm afraid something was wrong and dealer may been able to mask it at my point of purchase and now its starting to rear its ugly head.
This is my first Lexus ES350, not really sure if it's normal or not. I can tell you, when it warms up, I've jumped out of my car and have put me ear to the good and can't hear the tick. Should I be concerned? Is high idle with tick normal if it goes away when it warms up or is it a fair warning something is bad or about to go bad?

FSI engine ... I am getting this ticking sound on a cold startup. I've had the timing belt tensioner fixed under warranty and it went away for a while. However now the ticking is back. To be honest its embarrassing to start my car cold in front of others.

So I brought the Sonata home and she sat in the garage for 5 days as I was traveling. Then when I got back, I was so eager to take her for a drive. At this point she only had 72 miles on the Odometer. When I started her up, I thought the engine sounded rougher and louder than usual. My other car is a Turbo Diesel and that does not make this loud a clatter. After a few minutes of idling and driving, the engine quietened down quite a bit.

Twice this week our 2009 SantaFe (3.3l) had a squeal from the engine upon cold startup. The first time it was very cold (-20C or so) and this was louder and longer than the second time (-10C or so). The squeal lasted only a few seconds and trailed off to nothing. Each time the heater controls were set on defrost (fyi). In order of likely suspects, I suspect one of the following:
-compressor engaging and causing sudden increase in resistance on the belt or compressor engagement clutch noisy
-idler pulley for some reason causing belt to slip at first, but don't suspect idler bearing as noise disappears right away
-belt slippage due to resistance somewhere else--e.g. water pump or alternator.
This may not happen when I take the vehicle in for its next scheduled maintenance as by then the weather will likely be warmer. This has 76000 km on the clock.

I bought a 2007 Mini Cooper, used, at a Ford dealership in August of 2010. For nearly two years I loved this car and didn't have to pay much in the way of maintenance. I bought the car at 55k miles, and now it has 92k. Over the past year, I have noticed a rattling noise at cold startup, and it was especially loud in the winter, and I also noticed that the car consumes oil. As the oil got lower, the rattling got worse, and whenever I topped off the oil the rattling stopped. I brought this up at the MINI dealership (where I get all my repairs on the car) during a routine oil change and they didn't take it seriously.
Well, Tuesday morning on my way to work, there was a sudden loss of power and the engine started missing bad. I was almost to where I work when the car just couldn't hold and idle and stalled. It wouldn't turn over after that and it sounded really "sick". I had the car towed to the dealer, where they told me the timing belt tensioner failed and it allowed the timing belt to jump "a great distance". Apparently, these are "interference" engines (a term I learned because of this incident) so the screwed up timing destroyed the engine. The dealer said it will cost 8,000 to completely replace the engine.

A lot of videos have audio of a knocking sound, however my sound is more akin to an extra crank of the starter. It's intermittent at best, and I thought it was actually use error until I noticed the sound occurred a few times even when I briefly cranked the engine.

I hear a bit of exhaust leak noise from engine compartment only at a cold startup, it goes away in seconds. I am 700miles from home. If it's a nonessential fix i will drive home before fixing, or, if an easy gasket replacement, I have two more days here, and tools,garage, and competent support to diy the job.

I have an 07 SE (manual transmission). In cold climates has noticed a noise at startup on a cold engine when the temperature is below freezing (colder than -5C or so)?
The engine has to be cold (like sat overnight) and the outside temp has to be cold. Then at start when I turn the key, the engine starts fine, but as I release the key from the start to the run position I hear what sounds like the starter motor make a noise (short zipping sound).
At first I wondered if it might be slow to disengage, but if that shouldn't make a noise because the gears should be meshed ok? There is no noise with a warm engine, or with a cold engine on a mild day.

2011 Santa Fe 3.5 L
I've isolated this rattle down to the cam phaser( CVVT) in the right cylinder head. It rattles bad for 2-3 secs on cold start or after it sits for 3 hours.
I've put in 5w20 synthetic oil and synthetic Lucas additive and it cleared up the noise for short interval start ups.
I changed the cam phaser in the right head with a used one ( 40k ) but it didn't make a difference. I should change out the attaching cam as well.

It has happened three times now on cold startup my car makes this loud hissing sound then the car runs normally. Once a few months ago. Again a few weeks ago and this morning it was pretty cold maybe low 50's. I normally turn the key in the ignition to the "acc" position let it "ding" once then start the car. What could this loud hissing be that only happens on cold startup then the car runs like nothing happened? I called my local mechanic and he said he wouldn't know if he can't recreate the sound. Which you really can't because it happens once every blue moon but I wanna make sure I'm not ignoring a problem that could get worse.

It almost sounds like somebody is taking a small hammer and banging at the plastic cover on top the engine when the vehicle is started new from cold. After about 8 or 9 knocks it goes away.
Taking it to a dealer soon to get it checked.

Now that we've had negative temps, in the morning on these extreme cold startups, there is a spinning sound coming from the radio / cd that goes for about a minute then doesn't come back. (No cd inside.)
(I'd like to know something before I go into dealer). And no, it's not a subtle sound. Sounds like a cd is trying to eject. And yes, I'm positive it's coming from the radio.

Occasionally, when I start my 07 I hear a loud zip noise that seems to be coming from the front of the car somewhere. I know it's kinda tough to pinpoint. Something running against the teeth of plastic gears comes to mind.
I should also mention that it happens immediately after the engine has started, about the same time the self leveling headlights start to move.

I have a 2013 LS and am getting a maintenance reminder when I start the car. I was curious to see if there was a place to see what maintenance is due in the user interface. I have looked in Maintenance, but none of the dates are set. Does it just automatically trigger from some factory reset at 4500 miles or so for the oil changes?
