Lexus GS 2006-11 :: Direct Injection Making Engine Noise - Normal?
Jan 10, 2006
I have been wanting to get the new GS. My friend/coworker bought one a few months back and I have been going out to lunch with him many times over the past months. The only two things that kept me holding my breath forever are: (1) wood trim my wife would NOT say yes to a car with wood trim in it! Don't ask me why. And I don't feel like ignoring wifeys opinion. I can only tell her that if she wants a Lexus or a Benz, start getting used to wood ASAP (2) the new GS engine's idle noise seems to be a lot louder than any old GS and LS. Every time I get into my friend's car, I hear this ringing noise. It's actually louder than a lot of other Toyota-made or Honda-made cars. Of course once I get into the GS, I can't hear no noise at all which is great. But on the outside, it sounds like a car that needs serious valve adjustments done.
I mentioned the noise to a Lexus dealer two months back when I test drove a GS. He said the noise is from the new direct fuel injection mechanism. So it is a side effect of a feature, not a bug. The noise sounds like a very fine high pitch valve tapping noise. Imagine tiny pieces of metal ringing somewhere in the wheel well. Gen 3 GS owners, can you confirm what I am hearing? Is that noise normal? Do the other non-Lexus fuel injection cars exhibit the same symptom?

Accidently ejected my map dvd...located just under my Nav screen under a piece that has Lexus on it. It slides right up and the dvd came out. Cant get it to stay in now. Only makes clicking sound! So frustrated. How do I get the dvd player out? Removing the dashboard? My dvd player isn't in the dashboard though!

I have a '07 GS350 RWD with 121k miles. I had my transmission fluid drained and refilled at 90k miles.
Every time I go into reverse, there's a clunk noise. But all my gears shift smoothly.

My 2006 Prius makes this noise - like a groaning sound for about 5 seconds - when I shutdown the engine. Always happens when I am NOT at the dealership. Generally happens when the engine is hot. What this might be?

Engine oil has been changed and spark plugs changed. The engine is still making rattling/clicking noise. I checked with a mechanic and he indicated that engine needs to be repaired. Didn't say exactly what needs to be done and stated it would cost about $2200 for parts and labor. Why the engine keeps rattling and making the noise? Oh, before plugs were changed, the engine was shutting off at times when in idle mode.

2006 Sonata 2.4. A couple weeks back I posted about how my engine is making a slight ticking noise. It makes the noise consistently. I recorded a video of the noise. What it could be. Here's the video: [URL] ....

My 2.4L engine is making a clanking noise while running. When I checked the oil level today, it was low by about 1.5 quarts. There's no check engine light.
Car has 74K miles now. I purchased the car two years ago with 35K miles. I have always performed regular maintenance myself. The car had its oil control valve replaced at 55K miles.

I have 111,000 miles on my car and I take great care of the engine (or I try at least). I recently just had my first timing belt, water pump, and other belts changed 2 months ago with no problems at all. Recently, my engine just started making an annoying "whining" noise. It almost sounds like a bad transmission or something. However, it makes the same sound in "idle" and whenever I rev the engine the whining noise gets louder. I know the noise is coming from the left side of the engine and I think it may be my alternator dying. When I move the steering wheel around the sound does not get any worse too.

Recently my engine started making a rattling noise. It does not matter if the engine is warm or cold. In either condition it produces the same noise. The noise can be best heard at the back of the engine. My car is a Sonata 2.4 GLS from 2006 and has roughly 110000km on the odometer.

Tomorrow I'm dropping the car off to the dealer in hopes that they can find it.

We have a 2010 RX350. It makes a noise at a strange time. While in the garage with the engine off sometimes it makes a humming noise. The noise can last up to five minutes. It sounds like it could be coming from the back but not positive. The car has not been operated for several hours when the noise occurs. If I start the engine and immediately cut it off the noise goes away. I know that it will never do this if I take it to the Lexus dealership.

I have a 2010 Sonata V6 that I bought new. It has a little less than 50K on it. I tried to start it today and it made a terrible noise then died seconds later. I popped the hood and then started it again and the engine was shaking violently in the engine compartment and making a terrible knocking noise. I had driven it 12 hours earlier and it ran fine. I called a tow truck and had it taken to the dealer but if I know my dealer, since it is Sunday they probably wont get to it until Tuesday. Also, this car has had the signature V6 valve cover leak that has been fixed 3 times. I noticed it was leaking again about a month ago and I have just been checking the oil and adding it as it needs it. I dont think the engine ran out of oil because I checked it before the tow truck came and it was between low and full.

I noticed last night that the brake pedal was hard when I tried to start the car...then it softened up after I started the car.
does this mean my booster is starting to go bad ?
it usually feels normal and soft to the tap when I press the pedal and hit the start button.

Just got the dreaded p2440 code which is the secondary air injection valve failure. Not only do you get several lights on the dash, you also get limp mode with this code.
My GX is a 2011 with 46k, and even though several Toyota vehicles have had their warranty extended to 10yr 150k for this very system, Lexus has done no such thing.
The dealer was very familiar with this issue and knew it wasn't covered under any existing warranty. He said it's "around $2000" to fix because one of the valves is still under the intake manifold.
Even though I hate to "RIG" my GX, I ordered the bypass module from EBAY. It blocks the system off and tricks the ecu into thinking all is well.
For those not familiar, this system runs on cold starts for 30 seconds or so to warm up the cats, it has no other function.

I have a 2010 GX460 with about 81000 miles on it. I recently got the above codes and after researching it I decided to take apart the air injection valves, and also the motor to see what was going on.
Luckily these parts are very easy to access on our cars. Take the engine cover and front plastic cover off. The two valve are on either side of the cylinder head, and the pump will be on the left hand side, front of the engine bay.
I ordered two new valves, and ended up just cleaning out my pump.
Here are the Part Numbers:
VALVE ASSEMBLY, AIR SWITCHING
2570138100
VALVE ASSEMBLY, AIR SWITCHING
2570238050
This is exactly what happened: [URL] ....
Here is what both of my valves looked like:
Here is what the air pump looked like:

I notice a light ticking noise coming from the front of the engine. It sounds like it's coming from the puppies and not inside the engine. The dealer says it's normal. Is this normal for these cars. Mine is a 2008 v6 With 80k.

My wife's 09 Sonata SE AUTO 4-cycl.. I drove it last weekend and discovered a strange noise that can be heard after driving for a while at normal local road speeds.
The sound is like a combination of a whine and something that sounds like radio static. It can be heard very easily with the radio off and stopped at a red light. However, this sound also exist while the car is in motion. It becomes more difficult to hear as the road noise increase.
When I shift from D to N while stopped or driving, the noise immediately goes away. When I shift back to D, it sometimes comes back.
The consistent pattern seems to be that the noise will occur after having driven for a while at a consistent speed of at least 30-40mph. If I drive around the neighborhood for a while at low speeds and then stop, the noise will not be there.
I have not made effort to hear it from the outside of the car.

Recently traded in a 2004 ES330 for a Lexus Certified Pre-owned 2009 GS 350 AWD with 32,000 miles. Wasn't in the market for a GS but with such low miles and it being a CPO and the price was in my budget so went for it. Once I got it home, I am starting to notice the engine noise, like its kinda loud.
For some reason didn't notice it while doing the test drive but now, its like when I am driving, I get conscious about it so much so that I have to turn the radio on to take my mind off of it.
So was just curious if its the case with every GS. My 2004 ES had less of an engine noise, and I am thinking the GS is a CPO so it shouldn't be something out of the norm but still wanted to get some perspective here for peace of mind.
