Lexus GS 2006-11 :: Hesitation Developed In GS460 / Hard To Shift
Jan 28, 2016
A major throttle hesitation has developed in this car,that is so bad, sometimes when you put the pedal to the floor it doesnt want to accelerate at all. Feels like the car has a bout 25% power, it seems to shift very weird also, its like the car is trying to keep the rpms very low. I am not positive but it seems to occur mostly when the car is first started and still cold,or on very wet or humid days?it feels like the car is activating the traction control and the throttle plate is not opening all the way at wot?
Notice: already change spark plugs + A/T oil + filter

I am using 5-20 oil. Maybe should go back to 0-20 oil. Cant imagine the sensors are picking up on extra drag from colder thicker oil at that close of a weight? No codes are showing when the car is checked out.

Like the title says my 08 gs460 is pulling to the left, the steering wheel has to be slightly to the left for me to go straight, if I straighten the wheel out it goes off to the right, it has only been doing this the past two weeks or so. I went to Lexus and they agreed it was pulling and so they did an alignment, drove home, no change whatsoever, so I'm wondering what else it could be.

just checked my front fender liner(driver and passenger side) and noticed it was cut on the outside between the fender and liner from front of fender to back making a 2" gap above the tire. i bought the car used 2 years ago and never noticed it. i have 20k miles on it. is this a needed part to change? will water damage any items located under this fender lining? i figured they cut it out for an aggressive tire set up and drop???

Anyways, I've put MAYBE 250 miles on my '08 GS460, and Ive noticed what appear to be wear marks from my jeans (just regular Diesel jeans). I didn't have this issue in my SC400, my girlfriend's Cayenne, or any of the other cars I drive on a regular basis. Is this common for these cars? Could the leather just be low quality? Here's a pic .....

Dropped my car off at the shop due to the transmission lag from stop to slow speeds. Sometimes it feels like I was dragging sandbags. Then all of a sudden the car wakes up and goes.
The shop said the fluid "looks" fine but seems to think there might be too much fluid in it. So here we go with a transmission service. I hope this fixes it.

Noticed the lights jittery or bouncy when you go over bumps or imperfections on the roads. This cannot be right?

So I have had the car for about 6 months and on occasion I have noticed faint black smoke at start up. It usually goes away after the initial start up.
The car did get the recall or TSB on the engine valve ring issue? Not sure if that's related or not.
Also it has an aftermarket cat back Tanabe exhaust if that's relevant.

2008 GS460. 100K miles
I have noticed when I accelerate on a entrance ramp to the highway I notice the RPM meter jerks a little like it's trying to suck for gas or something else. I can feel it in the car too. This is the only time I have noticed this. I have replaced the spark plugs about 5K miles ago.
I did bring it into the dealership a few months ago to get the fuel pump replaced as I noticed a hissing noise under the drivers side read door. They said fuel pumps rarely go bad on the Lexus. The mechanic did some fuel pressure tests and said everything looks good. He also said noise is the return line back to the pump.

2008 GS460 ... When accelerating from a stop sign/stop light it get's stuck in 1st gear for about 10 - 15 seconds before it shift to second gear. I notice this as the engine rev's high and is not shifting. Shifter is in Automatic and not manual mode. Happened at least 4 times in the past 2 weeks. Dealership is unable to replicate the issue and transmission checks out fine. Guess I have to wait until transmission get's stuck in gear before I can bring it back in.

Yesterday I was stuck in traffic an smelled a burning oil smell. I thought I was the car in front of me so thought nothing of it. Later in the day as i was sitting and idling i smelled it again so knew it was my car. I came home took of the plastic covers and checked under the engine and oil filter everything was dry and clean. I checked topside could not find anything there either, very clean and no signs of oil or fluid. I can only smell it when parked or stuck in traffic while driving I don't smell anything. Usually happens when I have driven several miles.

2003 Explorer XLT.. All dash lights off finally... had to tape the new ABS connector into the socket on the driver's side. It kept losing signal. Now I am noticing that it is shifting a little hard, definitely not smooth, between 2nd and 3rd. It is not a hard jerk... more like a hesitation. could this be a solenoid? Should I look and feel for additional symptoms? Would it be risky to change out the transmission fluid? or use a cleaning additive?

My 2002 V4 Camry has developed a consistent hesitation. It only occurs during the first 15 minutes (or so) after cold startup. I've replaced: plugs, 2 O2 sensors, Mass Air flow, and EVAP Canister.
Am about to try the throttle position sensor.

I have a 2010 Sonata GLS 4-cylinder approximately 124K miles which has been hesitating on hard accelerations for about 8 months. It will usually do this when getting on an on-ramp for the freeway or if I need to do a U-turn and get up to speed quickly. What happens is I punch the gas and the vehicle acts as if it's not getting any gas and hesitates or stalls and then it finally takes off. Usually I see a cloud of grey/white smoke behind the car enough that I am unable to see any cars in my rear view mirror.
I do not seem to see a difference when the vehicle is warm/cold. I do not have a CEL nor have had one. I have replaced the MAP sensor, PCV valve and spark plugs (properly gapped). I have done a compression test and am getting roughly 180-185 psi per cylinder. I am not experiencing any oil loss/coolant loss, do not see any oil in the coolant or gummed-up or oily spark plugs. I have also replaced the transmission fluid, doing a drain and flushing the torque converter. I have also cleaned the throttle body, and am using a new air filter and the oil has been changed within the past 1000 miles.

Recently my wifes 2009 Sonata limited has started having a hard "clunk" when braking. It feels like a hard shift from 3rd to 2nd (or 1st?) during deceleration. Only really occurs when moderately cold and only during the first 10 miles or so of travel. What I should check?

I have brand new ( 800KM ) Accent with Automatic transmission and I noticed that it shifts from 1st gear into 2nd kinda rough. By this I mean that I can feel shift pretty good, and I don't feel shifts from 2 to 3 to 4. I don't rev engine high, typically shifts occur when engine revs around 2000 rpm.
I am not sure if it is a transmission defect or this is the way it shifts? May be I need to breaking my car first and it will go away?

I have a regular mechanic that I use, except for a recent plug change. The car now feels like it is shifting awkwardly, and at speeds of between 15-25 MPH, it's as if it has a hard time choosing a gear. Can improperly installed plugs have an impact on this sort of thing?

I got a new clutch & shift cables & fluid professionally done one year ago. I have only put 5k miles on it since. In the last two months the... gate/slot for 1st & 2nd have been getting worse n worse. All gears show sporadic rough shifting (read rough as a clunk or one tooth grind), but 1st/2nd are consistently rough & the gate seems to be getting narrower...
Environmental & operating temp, do not noticeably affect these symptoms.

I own a stock GS300 2007 RWD doing about 80K miles here in Thailand. I am facing one critical issue with my ride. While driving normally if I hit the brake hard the car seems to loose power then there is a hard knock from the rear which knocks the car forward. I think it is caused from the downshift of the gear, but I am not quite sure. It happens often in the same kind of situation.

I have a 2010 accent blue model with stick shift. been fine for 50k miles. Lately i have noticed an issue where i am in first gear and then when i push clutch in to go into second, the lever won't budge. it does eventually go in but it just isn't like it used to be. it happens say about 25% of the time. Since at higher rpms it won't do it but normal rpms it will.
Also, i just had a new short block installed, perhaps something is binding? If I sit in the car, stopped, i can shift into and out of all the gears perfectly. Maybe my 1st gear synchros are going?
