IS F (2008-2014) :: Car Is Very Sluggish And Up Shifts Slow Even With Sport Mode On
Jun 29, 2015
I recently traded in my 2013 Audi TTRS in a very limited edition color. For my 2008 Lexus ISF... With 71k Miles. And I feel as if the car is very sluggish and up shifts are slow even with sport mode on! My buddy has an ISF as well and he even said mine shifts slower than his. I was wondering if maybe the previous owner skipped a few key maintainence things to cause such an issue. And yes I know how to drive a care, yes it's in sport mode and yes the vehicle is warmed prior to stupidity. The last recorded maintenance was at 60K miles.

2016 IS300.
I've had it for 4 days now, and I've never had a brand new car so maybe this is a moot point. But the car simply feels heavy and sluggish. I'm at a little over 300 miles and the car just doesn't have much zip compared to my 2010 IS. Also, when I had the clear bra done at Lexus they gave me an identical loaner (2016 IS300 AWD) with around 800 miles and it felt totally different.
I remember with my 2010 reading that the car has to "learn" how you drive, etc. With my 2016 it'll go from a dead stop, them a couple of shifts in it drops to a super low gear. Even in sport mode it feels sluggish. In ECO mode... Well, lets just say that feels laughable.
Why was my loaner (which was identical to my new car) much zippier in the normal mode? Is this something I should be concerned about? The car runs fine, just no zip (yet).

So i noticed, when in auto mode, whether sport mode is on or off, it does the same thing. If i floor it from a stand still, the transmission takes noticeably longer to go from 1st into 2nd then from 2nd to 3rd, 3rd to 4th, etc. 1st to 2nd takes like a good second, kinda like this:
1st VROOOOM.....................2nd VROOOM..3rd VROOOM..4th.....etc..
If I drive it in manual mode, then it shifts just as fast. So this only happens in auto.

I've owned my 2011 IS-F for a couple of month now. I know the Sport Mode give the car crisper throttle response and it shifts quicker. Does the Sport Mode do anything else?

Just left my lexus dealer after getting an oil change. When I go WOT with the car in auto mode (whether or not in sport mode), it is very sluggish to downshift and when it finally does downshift, will accelerate very slowly above 4,000 rpm...almost no power.
In manual mode, no issue, accelerates great. All fluids are fine and no CEL. Gonna take it back to dealer in a few minutes.. Dealer has no clue what would cause the issue, they did not reset the ECU or do anything other than change oil and filter.

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 now have 1025 miles on my SE with the 2.4L. I will admit that I drove the car very easy during the first 800 miles. The car has always wanted to shift into higher gears way too quick even in normal mode. I was told that the computer may have been "trained" to be being a conservative driver. I am not a speed racer, but I do not drive like I have nowhere to go either. I have tried driving a little more aggressively (holding down the throttle and making it shift around 2500-3000 rpm when I can), but it still has not worked. When I make a certain turn and up a hill, the car chugs up the hill until it finally decides to downshift into a lower gear and it will finally go. If in sport mode, it does fine. I cannot leave in sport mode however because I do a lot of freeway driving and it will not shift into overdrive in sport mode, at least my car don't which I find odd??
Another problem area is when I first start out, I go up a grade on a highway. I have to literally press the pedal down about 3/4 way to even get it to speed (55 mph) within a reasonable amount of time... it was only around 2300-2500 rpm and I was almost flooring it. I pressed down the pedal more and it finally kicked into a lower gear and hit up to 3300 rpm and finally took off. Something is not right and I am not happy with my brand new car that I paid almost $19,000 for. I enjoy driving my 1991 Cadillac more than I do this new car and it is a heck of a lot faster than my Hyundai. I do love the MPG I get with the Hyundai... around 31 mpg on average versus 19 mpg on the Caddy.
I just don't know what is going on with my car. I am wondering if I need to get the computer reset or something?

I've always wondered why the transmission automatically shirts to 4th gear when I switch to sport mode! Is this normal??? It's an i4

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.

I am feeling disappointed just came out of a lemon law suit with a kia optima I bought two years ago. I figured we'll I should buy a better brand this time which my brother recommended cause I was going to buy another Infiniti I always had good things with those cars. But the last 2 nights I have been hearing a squeaking noise in my rear end of my brand new IS 350 F Sport. Only in sport plus mode. I was driving home from work at 2 am and driving through a canyon road cause I want to see how this car does as soon as the road got a little bumpy I was hearing a squeaking noise come out of the rear of the car. Then I get home and I hear it going over my speed bumps in my complex of my condos. So I think we'll that's odd. I take it out of sport plus mode and back to eco and drive around the complex again and it goes away. Remind you I have 484 miles on the car.

I have been driving my 2014 Sonata GLS in Sport mode with no problem. However, two days ago the engine got extremely noisy. I checked the Comfort and Normal modes - definitely no scary noise. Is this common?

When speeds are 40-50 mph range and then back off a bit to get back up to speed it reacts very slow. Will get up to highway speeds on an easy acceleration, but when I try to get back up to speeds quickly or catch up then truck is sluggish and slow to react. Was told it may be a stretched drivetrain? Is that possible?

So, when the 2008 Sonata Limited (4cyl) was started yesterday, the + sign by the shifter lit up (first time ever since we had never used Sport mode). The car was indeed in Sport mode and wouldn't come out of it regardless of how you moved the shifter or to which gate, etc.
Took the car to a local well-regarded auto shop today and they said when they started it up it was not in Sport mode and worked correctly. I picked it up and sure enough, the plus sign was off and the car was in normal auto mode. On the way home, the + sign lit up again and yes, it went into Sport mode again and won't come out.
Btw, this Sonata has 68K miles and has already had two full brake jobs. It has nothing to do with this issue.

My friend just bought his ISF two weeks ago. It's bolts-on. He has an issue...
While hard accelerating in all modes the car some times shifts @5500 RPM...
What the problem is?

I have an 06 sport edition with 83k miles. Never a problem or complaint. If I'm not going crazy, I think that I am noticing a very slight performance decrease. I bought this with 63k miles on it and I'm not 100% sure what servicing was done before. Where to start, spark plugs or something like that?

I have a 2008 ISF with a k&n intake and QTP exhaust cutouts. About a month ago my car died on me and when I restarted it, the car went into limp mode. The "check vsc" light is on along with the traction light and CEL. I took it to my mechanic and he said I needed to replace the MAF sensor and I did. 100 miles later the car went into limp mode again. So I took it to a mechanic that knows Lexus vehicles very well apparently, and he diagnosed it to be my intake. So he replaced it with the stock intake. Now I've driven another 100 miles and the problem has come back again. The car is throwing all kinds of codes when I connect the obd2 scanner to it.
It is throwing p0031, p0037, p0051, p0057, p0102, p1360, p1361, and a whole bunch more.

Is there a way to switch the down and up shift in "M" mode. ( backwards for up shifts and forwards for downshifts).

A few months ago I developed a slow leak in my drivers front tire. I took it to a local tire shop and they told me small sections of paint on the inner part of the rim that sits on the bead of the tire was corroding and flaking off causing a small air leak. They sanded it down and resealed the paint and it stopped the leak. I asked them if it happened to this rim, could it happen to all of my rims? They couldn't answer that, but now I think I know the answer. 2 of my other wheels now are losing air and I bet it's the same problem. Is there a recall of some kind? Dealer says since my car is out of warranty, they can't do anything.

I noticed a ECO light pop up on the RX350 F Sport when driving.
What exactly does this mean? (ie. poor performance, not full pwer?)
Is there anyway to turn this off?
