Lexus IS 2014+ :: 2015 IS350 Clumsy Idle - Fluctuating RPMs

I sometimes have a weird idle. When my car is cold the idle is fine. When the car is warm the idle is fine. The idle only gets weird sometimes when I drive the car, park it for an hour or so, start the car again (temp gauge is about half way from complete cold start to complete warmed up) and I get a fluctuating rpm tach. It bounces around 50-75 rpms for a while. You can definitely feel it in the car and if you stand behind the exhaust you can here it slightly burp/hiccup. The car has 16k miles on it and it's a 2015. The gas mileage and performance has not changed. I don't know if it has done this since day one as I usually have my radio on. I heard it once now I make a point to see if it does it. I also don't have any CEL on.

Lexus IS 2014+ :: Static Sound Coming From Dashboard Of 2015 IS350 F Sport

I have 2015 IS350 F sport. At 400 miles I started hearing this static sound which seems to come from the center or the driver side dashboard. I don't hear it if the car is not moving but as soon as I hit 5-10 mph and above, it becomes audible. I tried pressing the dashboard to see if there are loose areas but couldn't find one. Also, I thought they may be coming from the center speaker but the sound doesn't change whether the stereo is on or off. Of note, it is more audible along bumpy roads.

Lexus IS 2014+ :: 2015 IS350 F-Sport Seats Appeared To Be Hotter With AC On

I just bought my car a few weeks back in July. I noticed that the seats appeared to be hotter with the A/C on. It turned out, I was right. With the seat heaters OFF and A/C ON, the seats would get hot.

I've posted an infrared video here .... Infrared showing seats of 2015 Lexus IS350 F-Sport - YouTube

For reference, I also made a video of normal heating (e.g., seat heat ON) ... Infrared of normal seat heating - 2015 Lexis IS350 F-Sport - YouTube

And you can see that the heating areas are different.

The dealer says this isn't happening. 2015 IS350 F-Sport

Lexus IS 2014+ :: 2015 IS350 Started Beeping And Red Message Showing On Gauge

So I got my IS350 F-Sport AWD a couple weeks ago and I'm loving it so far. I just passed the break in period a few days ago . I just had a question about something happened today though. Basically I was on the highway and I was coming off of an off-ramp at about 90 km/h (~55 mph). This was a relatively sharp ramp but I was slowing down as I entered it. Anyway, the car started beeping and I saw a red message in the center of the gauge.

Unfortunately, it was there for a split second and I didn't get to read what it said. Later, after parking the car, I checked the "messages" view in the gauge cluster and there was nothing there. There was also no check engine light or anything on after either. The car seemed to drive normally before, during, and after that. Was it the VSC/TC system? Or is it something else?

I believe this is what I saw. Is it possible for it to have detected the curb coming up and that I was going fast? Does the Canadian F-Sport 3 package even have a PCS? I don't see anything about a PCS when I look at what's included in the package, but I know that it does have the radar cruise control/rear cross-traffic alerts so it doesn't seem out of the question that it could detect the curb.

Lexus IS 2014+ :: Humming Noise Coming From Transmission After 185 Miles On Vehicle

I have a 2015 IS250 Base with TRANNY PROBLEMS

After 185 miles on the vehicle, I reported the problem to Lexus and the Tech that test drove with me said I was hearing things. Apparently there was a humming noise coming from the transmission.

The noise became evident and consistent, took it back in again, the Tech says its normal and DI engines make a lot of noise.

After six months and 2700 miles the noise became annoying, Tech said they will look into it and confirmed it is unusual. Test drove about 5 other new 2015, used 2014's and no humming noise present.

Engineers made two trips over a five week period from Cali. They changed the alternator, which at first they thought was the problem, then they started looking at the fuel pump on the engine, then they swapped out a tranny from a loaner and the noise disappeared. They took out the loaner tranny and ordered a new tranny and installed it.

Lexus IS 2014+ :: IS350 F Sport AWD - Thumping In Trunk When Driving At Moderate Speeds

Model: 2014 IS350 F sport AWD

When I go over a medium sized bump at moderate speeds, there is a loud thump coming from the trunk area. My trunk is empty and everything looks fastened down securely. The only thing I notice when I check the trunk, If I hit the center of the floor board, it imitates the sound almost identically. I checked the spare tire... everything.. In my trunk is the floorboard and the lexus carpeted mat.

Lexus IS 2014+ :: IS350 F-Sport Driver Side Door Rattle Especially On Rough Road

I got my all new Lexus but driver door has been rattle since 400 mile. It's like plastic vibrating and creaking.... I think it's the door panel is making the noise especially on rough road. When it rattles, I can place my hands on and share the vibration, then the noise would be somehow suppressed.

The problem is that I took it to dealer and they, as usual, cannot reproduce the problem! I took down the door panel myself, tightened all screws...and the noise...got worse....

Lexus IS 2014+ :: IS350 F Sport - Slight Clicking Noise Near Steering Column

Just received my car back from the service department and noticed a slight clicking sound that isn't too loud, it's mechanical sounding.. Quieter than a ball point pen retracting I'd say. It clicks every quarter of a turn while stopped and low speeds.

Lexus IS 2014+ :: IS350 F Sport Making Noise From Driver Front Wheel When Applying Brakes

My car is making this noise from the driver's front wheel when applying the brakes and EVEN CLUELESS AND SURPRISINGLY the noise shows up when cruising at low speed (haven't try freeway speed yet) without stepping on the brakes.

This just happened to me tonight, car is around 10,000 miles, I'm going to take it into the dealer to see what the hell is with Lexus. I suspect it might be the rotors and built in brake dusts, I just don't know, but the noise is unusual enough to be concern about.

I doubt it's the built in brake dusts because previously I've not washed my car/ wheel for a longer period of time, but I'm not sure. Could it just be that my rotor is done?

I know the front brakes need a replacement soon, but it shouldn't be my brakes since the noise still shows up even when I don't step on the brake pedal, unless the car brakes for me itself......

I cant take it into the dealer until weekend, hopefully it's safe to drive around within the next 2 days.

Lexus IS 2014+ :: Whistling Sound From Driver Side Of Car

I have noticed that at highway speeds, 55 + MPH, there is a whistling sound coming from outside the car, I can hear it more on the driver's side of the car. I checked all the rubber parts on the two doors and everything seemed to be in place. Is this normal? I probably only noticed it because I had the volume on the radio really low, but the whistling sound sounds like it's right in my ear. I got my roof wrapped so I thought maybe part of the vinyl came up and was causing that but the wrap is sound in place.

Sonata I45 (LF 2015+) :: Noise Coming From Back After Shutting Off Motor

I have a 2015 Sonata 2.0T limited, and there is a noise coming from the back, driver's side, after shutting off the motor. I've taken it in 3 times for this, and each time they say nothing is wrong; but, I've driven a lot of cars and trucks, and I've never heard a noise like this.

I'm guessing it's some kind of gas tank related valve that's closing, but it's making a very loud noise each time.

IS F (2008-2014) :: High-pitched Hissing / Whistling Noise Coming From Engine At 1500 RPM

Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.

I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..

I have a Takeda intake installed and I re-tighten the fittings.

TrailBlazer :: Intermittent Whistling Noise Coming From Rear Driver Side

I get this intermittent whistling noise coming from the rear drivers side. Sounds like a coffee pot whistling on a stove. After I drive about ten or twelve miles it goes away and diminishes into a hissing noise. Is it possible the fuel pump is failing? I have a 2005 trailblazer with 105000 miles.
