Lexus GX 2010+ :: Sluggishness And Hesitation When Attempting To Accelerate
Feb 8, 2015
Previously, I would sometimes experience sluggishness and hesitation when attempting to accelerate. Now, the problem has become worse. Also, previously the issue occurred when I suddenly needed to accelerate to pass another vehicle. Now, I can feel it from take off, you really hear the engine struggling(the kind of sound you hear on an old 4 cylinder vehicle trying to go uphill). Sometimes, I feel the engine is struggling to keep the vehicle at a constant speed on a level road. Tried fuel injector cleaners like BG44K. While these injector cleaners are in the gas tank, the car runs smooth and has decent acceleration. Later, I return back to square one.
It is not that I have high expectations and am a power freak. I used to own a 2004 RX330 with 150K miles and that car ran better at 150K without any tune up then my GX460 with 60K miles. So, you can imagine my frustrations.
One more thing I noticed, it runs better when I just gas it up. One theory, could be the fuel filter is clogged. When I am suppose to change the fuel filter on the GX460?

I have a 2000 Ford Explorer XLT. V6, 4x4
At very low speeds (5-10 mph), attempting to accelerate while turning (like coming out of a parking lot OR out of a curve) the transmission fails to engage. I hit the gas, the RPMs go up, but it doesn't get into gear. I will let off the gas, give it a couple seconds, hit the gas again and usually it engages. Sometimes I will have to repeat this step a second time. This problem started very slowly and has gradually gotten worse. It happens about once a day.
Concerned, I took it to the local Ford dealership and they have thus far changed/flushed the transmission fluid and replaced the filter. The mechanic said he found no metal shavings in the fluid, which might indicate grinding gears. They also said there were no codes coming up pointing to a transmission problem. It is still having the same exact issue however. The trouble now is they cannot "verify" the problem. The mechanics have put 40+ miles on it in similar driving scenarios and it will not act up for them.
After a couple weeks of back-and-forth, I'm really frustrated. My understanding is that they're "not sure" it is a transmission problem. They don't really want to open up the transmission case until they have a place to start. It should either be something mechanical with the transmission or a problem with the computer that controls the transmission, right? After getting off the phone with the mechanic today he said it might be a sticky throttle body?

My dad recently bought a 2011... He says now there is a hesitation on acceleration?? Don't know if it was always like that or not he's owned the used car only a few months.

Both front doors continuous clicking and attempting to lock (even though they are already locked) every few seconds while driving. All switches appear to be working normally. Tried disconnecting and reconnecting battery, I suspect the door lock ecu but can't find it's location. My next resort is to pull the door lock fuse so that I don' t damage the actuators.

As I have experienced hesitation on acceleration from a stop, I found a TSB # L-SB-0154-10, that addresses this condition for the 2010 SC430. It was issued in 12/1/2010. I am not sure if it would apply to any other years. The TSB entails re-flashing he PCM with updated software.

Experiencing a low speed transmission surge or hesitation when applying first applying the gas at parking lot speeds.? I especially notice it when traveling downhill or a slight decline. The motor revs as if in neutral then the transmission catches on. I mentioned it to the dealer at the 1000 mile check up and they said they could not find anything wrong. I'm getting ready to take it in for the 5000 mile service.

I just purchased an l/certified 2013 RX 350 (34K miles) this past weekend. I did not notice these issues on my test drive. I've started to notice that when taking my foot off the gas pedal (while not resting near the break pedal) the vehicle goes through a series of easy coasts and then some resistance (as if using an engine as break on a truck with a manual t,) then returning to a smooth easy coast.
I've also noticed that when accelerating at a slow speed from stop (I'm in traffic) there is a bit of a hesitation, like turbo lag, yet this has no turbo. The lag seems to be there even if I want to accelerate aggressively.
I hate to get tied up with a dealer service department already.... "Cant duplicate," or "that is normal operation," or "Computer codes check out." Looking for reinforcing information so I don't have to take it in once a month for an unknown amount of time.
Of our three other cars (2015 Prius, 2002 Nissan Altima, and (pre-tran fail) 2002 honda odyssey) none experience anything like this.
Our household is dumping a 2002 honda odyssey for repeated transmission failures never covered with goodwill. All service was at a h dealership and manufacturer schedule was followed. I'm already sensitive to the manufacturer/dealer relationship.

I have a 2014 RX, which is still under warrantee with 35k on the clock. I bought the SUV knowing i wanted to upgrade the look to the F-sport..... so, I did body wise and bought a set of wheels too.
On stock wheels 17s when accelerating from a stop, its smooth as butter. but upon throwing the new F-sport 19s on.. when i go to accelerate, it feels as if i have a bowling ball in my trunk.. its a "thud" noise. totally weird, i deemed it fixable by the dealer and took it in.
I did, they swapped out a NEW rear diff. for me thinking it was going to fix it. sure enough.... it didn't. I swapped lug nuts, studs, made sure it was hub-centric wheels, even went to verify if the wheels we reps or not.
So to go further in depth, i swapped out just the fronts, its a more faint thud, but with all 4 its more audible and feels worse. Here's where i am at, id put them on and dont mind the thud noise if i know its not hurting the car.

I have found that when I accelerate quickly, while entering the expressway or getting around a semi for example, a burning smell enters the car. I imagine it's oil but uncertain. The smell occurs shortly after the quick acceleration and it doesn't occur consistently.

I'm having with the first startup in the morning. The car turns over fine, but when I accelerate there is a noticeable hesitation. This was only occurring for the first 20 seconds, when I accelerate out of my driveway. Now, it has gotten progressively worse. Still not stalling or anything like that, but it has become more pronounced. I have an APR stage 1+ with a Carbonio intake. Others mention they were experiencing a similar situation. I have tried idling before shutting the car off as well as letting the car sit for 30 seconds after I start her up. Im wondering if I disconnect the battery and allow the ECU to reset might work.

I have been experiencing a slight hesitation when I accelerate from a stop. It almost feels like its going to stall for a brief second then it picks up and accelerates normal until I'm at a complete stop again. I have the 2016 sport with the standard 2.4L. I currently have 2200 miles on it now and when I go in for my initial suggested oil change at 3000 miles ...

The Electronic Power Control light in my 1999.5 Jetta GLS VR6 came on a day or two ago. Now it hesitates like crazy even after I've already pulled out and am trying to accelerate. Is there any common problem/malfunction that would cause the light to come on, and is there any correlation between the light and this symptom? Also, the check engine light came on.

I have a 1988 Toyota Camry. I was driving to work this morning, the car was driving fine. After about 10 mile or so, I stopped at a red light, when the light changed the car wouldn't accelerate it seemed to have a really bad hesitation. If i let off the gas it would idle fine, none of the warning lights are on. However, when I give it more gas the car doesn't have any power at all. It has plenty of gas in it and the exhaust has no signs of any oil or water in it. I was thinking it may be a bad fuel filter or a tank of bad gas.

My isf for couple months now and love the car. I have an 08 which only 7k miles on it. Lets say at a stop I start to accelerate, I notice a slight hesitation before it picks up around 1-1.5 rpms. Under hard acceleration I don't notice it, but with nice and easy acceleration that slight hesitation is kinda annoying. Not sure since car has such low miles on it if I need to run fuel injection cleaner or something, of if something else could be wrong. I kinda mention it to the lexus service manager and he said something that next time I bring the car in that he'll let the mechanic do a tranny ecu update of some sort? I didn't know that there was such a thing.

This morning as I was driving to work, my truck hesitated as I tried to accelerate from a stop sign. I pressed the pedal and nothing, almost felt like it was going to stall. After about 3 seconds it started driving again and I had no further issues. It seems to only do this in the morning when it is cold. It has done this a couple of times before, but usually it recovers almost immediately. I had no CEL come on. 2007 F150.....

My ranger is an 89 but it's got a 91 motor in it, 2.9 V6. When I accelerate it hesitates before actually accelerating which makes me think the TPS is bad. Probed and tested and I got .85V throttle closed and 4.65 at wide open. Specs call for .8V - 4.5V
I'm not sure if there's an allowance of fluctuation, but is that high enough to point out a bad TPS? If it's not the TPS, is the ignition timing off or what else could it be?

For months I have had a hesitation in this truck when i go to accelerate, and at times you can even feel a little buck with the cruise set at 70MPH. It has gotten worse and worse. When i start pulling a trailer good luck, it will do it but its terrible, hesitations and misfiring,
There is always a misfire/hesitation. Will Idle nice After its warmed up. Sat for 2 weeks fired it up and it had a HORRIBLE idle for at least 1-2 min. This is new now it wont idle when cold. Now I had one code Cylinder 4 misfire, cleared the code never came back 2-3k miles later still not back on -
replaced coil packs
New plugs
New wires
Fuel pressure test good
Checked the Heater hose - not leaking and nothing in the hole.

So of course the dealership isn't going to diagnose this since "the car's not supposed to be driven that way" - but I get a nasty rumbling noise when I accelerate from a dead stop with wide open throttle. It only lasts for the first few thousand RPMs in first gear, and after that it is gone.
I was guessing that it might be the transfer case or something like that, but it's really hard to tell. I do have AWD. I did not have any such problem in my previous GS, which was a 2007 (current is a 2010). It's worse when I accelerate around a corner, and it also makes a small noise when I'm going above 80ish mph, which of course the dealership isn't going to diagnose either.

I have a 2003 Toyota Tundra V6. The problem I have with it is it hesitates. It does not happen ALL the time but it is very frequent. Sometimes it happens when I try to accelerate from a dead stop and other times while I am driving along (does not matter what speed). It will usually hesitate for a few seconds then everything is normal. The check engine light thus not come on.
I took it into Toyota. They duplicated the problem on the first test drive but did not have their equipment hooked up at the time. They kept the truck for over a week and finally got it to happen again. I guess they must have only been going on short test drives because it happens to me multiple times a day. They told me it was the throttle body and it needed to be replaced. My jaw hit the floor when they told me how much they charge to replace it. I ran this by a couple of friends who work on cars on the side and they said it sounded like the mass air flow sensor needed to be replaced. Since this was much cheaper than a throttle body, I replaced that. However, it did not solve the problem.

I have hesitation as I accelerate especially starting from a stop. It will continue until cruising speed. Funny thing is when I put the cruse control on the hesitation stops and it runs fine. If I want to accelerate while on cruse the hesitation starts again until I let off the accelerator. Is it the TPS ? I changed it two months ago.
