Lexus SC430 :: 2010 - Hesitation On Acceleration From A Stop
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.
View 8 RepliesLexus RX 2010-15 :: RX350 Engine Brake And Acceleration Hesitation
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.
Lexus GX 2010+ :: GX460 - Low Speed Transmission Surge Or Hesitation
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.

View 13 RepliesLexus LS 2007+ :: Fuel Fault Causing Hesitation Upon Acceleration
It was the fuel. I had been experiencing a hesitation when going from a cruising speed...to WOT (wide open throttle) situations. The car would kind of just hang there for a couple of seconds, not really going anywhere. This situation was a bit - I wouldn't call it scary - but I would call it something I needed to be concerned/mindful of when pulling into traffic or switching lanes on a highway, etc....it made you have to take into account how much more space you'd need to do such a maneuver.
Well the problem is gone, it was the fuel. And it was my own fault. I was buying Super one week, then supplementing mid grade the next...mixing the two and lowering the octane level. Plus I was buying the gas at a station that was cheap. My logic was that I drive 600 miles a week...I'm trying to save a few bucks, etc...the guy I bought the car off of said he was doing the same thing with the fuel (and he's a Lexus tech)...and for the most part I didn't notice much of anything in loss of fuel mileage, etc.
The hesitation wasn't something that really bothered me because I usually don't find myself in situations where I have to mash the gas pedal into the floor, but I did want to know why the car was acting like that. After reading through a bunch of threads I came upon one post that said most of the time it's the fuel, but there is a reprogramming procedure as well. For me it was the fuel. I know others have solved an entirely different problem with the quality of their oil (TGMO).
So if you're going with a lesser grade of fuel...yes your miles per gallon won't really change...and no you won't be able to tell much of a difference...but don't be surprised if your car doesn't want to move in hard acceleration situations for a spell (I imagine it's the knock sensors kicking in).
Lexus ES 2007-12 :: Hesitation On Accelerating - Transmission Firmware?
I have sent my 2008 ES350, 47K to a dealer since it has a bit hesitation on accelerating; RPM goes upto 3K easily to get engaged to next one.
The dealer told me that no hardware problem but they did update a tranny firmware. They added that it may work right away or work after 3~4 fuelings.
What would be next step?
Lexus GS 2006-11 :: 2008 GS350 Transmission - Hesitation At Low Speeds

I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.
View 19 RepliesLexus GX 2010+ :: Sluggishness And Hesitation When Attempting To Accelerate
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?
Lexus ES 2007-12 :: Transmission Slipping - Car Will Rev Up With No Acceleration
I purchased a 2007 ES350 from a Toyota Dealership (64K, now has 66K). I purchased a warranty for the vehicle. Over the last couple weeks I have begun to notice my transmission is slipping - the car will rev up with no acceleration. It will usually catch on the second attempt of pressing the gas pedal. I notice this behavior usually after a cold start in the morning as I am leaving for work.
Before I go into the dealership to tell them about my potentially expensive problem, I want to ensure I go in knowing as much as possible. I have already found a ton of issues surrounding various transmission flairs at varying gears. (TSIB: TC001-06)

View 6 RepliesLexus GS 2006-11 :: 2008 GS350 CPO - Transmission Shudder / Shake On Light Acceleration?
About 6 months ago I bought a '08 GS 350 CPO. Love the car but after a month or two of ownership, on light acceleration 3rd and 4th gears will shudder. The whole car will buck and shake, but if I give it more gas it will smooth out. Doesn't seem to be the engine, I suspect more the transmission. Of course I took it in and they "could not reproduce the problem"... Is this just a normal characteristic of the car?

I just purchased a new 2015 RX 350. As I accelerate from a stop at normal speed it sounds loud to me. The loudness disappears at 30 mph or so. I have a 2001 RX 300 that does not do this. I like (a lot) the new 350, but am surprised that the engine noise is louder that a 15 year old RX.

I bought a 6,000 mile RX back in december and notice the vibration at slow acceleration.
It sounds like it's coming from the rear of the vehicle. It stops when it gets up to speed. I looked for anything lose and don't notice anything underneath.
I'm not too impressed with my local dealer so far to have them look at it. It sounds as if something is loose inside the muffler. It does not vibrate upon rapid acceleration.
Santa FE SM (2001-06) :: Hesitation On Acceleration
It'll do okay when I am not flooring it, but when I do floor it there's a pretty noticeable lag and then VROM it'll take off like a bullet... This car has a manually operated throttle control, are there any adjustments I can make to make the truck more responsive? 2.4L 4Cyl....

View 13 RepliesVolvo :: 2014 XC90 - Hesitation And Very Little To No Acceleration
Have 2014 XC-90 w/10k miles. Problem is sporadic (has happened approx 10-15 times over past year).
From standing stop (stop light, etc) -- press on accelerator and VERY LITTLE to no acceleration. Engine continues to run smoothly -- no indication of fuel starvation, no roughness --- just no acceleration. It does NOT appear to be transmission oriented because when it finally "kicks in" there is no feeling of transmission shifting or wild tach movement (to indicate that there was a changing of the gears, etc). I get things back to "normal" by pumping the accelerator (usually a reflex action because the are vehicles behind me wanting to "go"). VERY disconcerting issue.
Local Volvo dealer says "cannot find any error messages", etc. My only complaint with the car -- second XC-90 and 5th Volvo.
