Lexus IS 2014+ :: IS350 F-Sport Steering Resisting At Higher Speeds?
Aug 5, 2013
2014, IS350 F-Sport owner. Noticed the steering become resistive at higher speeds?
When I drive at freeway speeds (70-80mph) for, say, >10 minutes, I get a very large increase in the resistance in the steering. This is combined with a complete lack of caster response, resulting in very difficult control.
This occurs in all modes, and once it happens I have to come to a complete stop before the steering once again feels normal and the caster response returns.
I've had it in the service dept. since day 4 of owning the car, but no "error code = nothing wrong". They're now trying to convince me that it's supposed to work this way because of VGRS, but I'm calling B.S. on that. The car's handling and performance are decreased at higher speeds; definitely NOT what an F-Sport car is designed to do...

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.

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.

I am hearing some whine engine during acceleration. Is this normal?

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

So today during my drive I looked down and noticed my check engine light come on! The car has 7k miles on it!! All I've done to it was the ARK cat back and k and n drop in filter. I'm guessing O2 sensor but it's crazy to think a car with 7k miles had a bad sensor. Noticed the car was running a little rough lately but noting too crazy.

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.

I noticed just recently my 15 IS350 F- Sport doesn't have elapsed time in the multi information display. Instead it has 2 different average fuel economy spots under Driver info 1.
I remember seeing it on a 14 IS base, is this something different 15 or F-sport? Is there a setting to get it back?

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....

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.

Recently I started driving on eco mode to have the smoothest ride/acceleration. However, yesterday I wanted to get my dose of sport mode and WOT, so I switched to sport mode and stepped on the gas and during a small curve I felt the car steering is stiffer than usual, so I thought it could be due to speed. After that I reduced my speed and tried switching between sport and eco back to back and the sport mode steering actually is stiffer and more responsive! . I was surprised because my car is not the F sport, it is the normal is350 with tech package, and Lexus didn't mention this when describing the sport mode.

anyway to set it up so it always starts in S or S+ mode so I don't have to always remember to do it.

It's just the throttle response? Is steering or brakes enhanced or is it just me? I know the Is250 didn't get the suspension option like the IS350.

I am curious about the new 2016 IS3XX cars - it looks like the mileage is the same, displacement the same, engine the same (?) so what do they do to the car to reduce the HP by about 50? Seems strange that anyone would buy a 300 - do they want less HP and torque?
I wonder how hard it would be to reverse the "detuning" to get he IS300 up to 306 HP?

As winter comes in full force to NYC I've been experiencing some rough idle on my is350 AWD even after warming up my car for about 3-5 min. For ex. when I am at a stop light and have my foot depressed on the brake it feels as if the engine is revving higher than usual as if the acceleration pedal is lightly being depressed while I am braking. Is it just due to the cold weather?

I noticed not too long ago that when I drive my car after being idle for a long time, the gear acts weird. Bought the car in July 2015 and has only 2,600 miles on it.
Usually in S or S+ mode the gear doesn't go past 5th gear on local. However, in Auto mode it goes up to 8th gear when I am not even accelerating that hard. In manual shift mode, the gear is delayed by about 5 sec, using the paddle shifter. It happens once and it goes back to normal.
I have not talk to the dealer yet. I wanted to get a proof before I do, so they dont tell me nothing is wrong with the car.

So I've got 13,375 miles on my car and I was at an intersection and when I put the car into sport mode the check engine light came on and now it won't go off. My car isn't displaying any other messages or lights and the gas cap was definitely on all the way. What could trip it so early in the life cycle, had the last scheduled maintenance 3 months ago too???

The car is about a week old. Today, the NAV system (ML version), re-started a few times and then shut completely off. Re-starting the car does not work. Got a totally "off" screen and no sound. 2014 350?
Is there some way to reset it or turn it back on? I can't imagine that a brand new Lexus would have this sort of issue.
