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 LS 2007+ :: LS460 - Hesitation / Lack Of Power When Accelerating From A Stop
I have a 2007 LS 460 with about 50,000 miles. Some 18 months ago, at about 35,000 miles,right after a service, I began to experience hesitation/lack of power when accelerating from a stop. Lexus fixed this by doing a software update to the transmission.
All was well till last month, when again right after a service, the car hesitated and totally lacked power , most noticeable from a rolling stop. Revs would very gradually climb to 5,000, with foot flat on accelerator, yet car barely moving. Once speed built up to highway speeds, car reacted normally. Took it back to Park Place Lexus who held the car for 10 days and did a major job changing the cylinder head, I think per L-SB-0033-08.
A month later, the hesitation/lack of power is even worse then before! I suspect the issue is the transmission, and the big surgery on the engine done last month was not required. After nearly being hit trying to merge with traffic today, the vehicle is back at the dealership, and I took their head tech for a drive. He experienced the problem, but did not venture a solution. He told me they take instructions on what to do directly from Lexus.
Lexus LS 2007+ :: Loss Of Power - Hesitation When Accelerating After Turn Intermittently
I have owned this car for six months. The car now has 39K. The problem is getting worse.
Re: Lexus 2011 LS460 AWD
Subject: Hesitation / momentary loss of power when accelerating after turn.
When accelerating after a sharp turn with light to moderate acceleration, the car will have a momentary loss of power for about 1, 2, or even 3 seconds. This does not happen often, but perhaps once every two weeks and I cannot replicate the problem despite attempting to do so.
In all cases, I am talking about DRY pavement. It always happens after a sharp turn usually to the right. (Probably because most sharp turns are to the right actually it only happened once on a left turn that I will describe below.) Acceleration is light to moderate NOT hard acceleration.
In one case it caused a serious situation. I had just purchased gas and was entering a busy freeway. When accelerating, the engine had a total loss of power for a couple seconds as a large semi truck bore down on me with its air horns blaring.
I have a strong clue that may debug this problem. Once, when turning left, the car suffered a total loss of power. There was no traffic and I kept my foot lightly on the throttle. The car remained unresponsive. The engine did not stop, but it did not respond and remained this way for at least 5 seconds until I took my foot off the accelerator and then back on to the accelerator. During this period of suspended throttle, I noticed that on the right side of the dash an orange alert symbol was flashing I think it was a swerving car? I assume this indicated that the car was losing traction and the computer decided to cut power until traction was regained. But the pavement was dry, and the acceleration was normal. In no case did I ever sense that one of the wheels was slipping.
Toyota - Camry :: 2012 - Hesitation Before Accelerating When Trying To Get Back Up To Speed After Making Turns
Nearly new Camry with 9,000 miles. When trying to get back up to speed after making right or left turns, there is a definite hesitation before accelerating. No hesitation when accelerating from a dead stop. Also transmission kicks down at very small hills/grades where if not on cruise control, it would not need to "kick down" to maintain speed. This is a 4 cylinder engine and provides adequate power when not running in "cruise". I suppose this is just the nature of the breed. Except for these two small problems, it is a fine comfortable car.

I purchased a 2007 Sonata with the 3.3L about six months ago. I really like the car, it has a lot of good features and lots of power; however, I am starting to have problems with the car. On accelerating from a stopped position the car almost quits (hesitates severely) and then picks up and goes on normally. Also, between 40 and 50 mph the car starts to jerk pretty hard for a few seconds and then it straightens out and runs normally again; it will do this repeatedly if it is kept between 40 and 50 mph.
When this first started happening the CEL would come on randomly and stay on for a day or two and then go off. While the CEL was on I took it to Autozone and had them pull the code, they said it was the crankshaft position sensor. Well based on the symptoms the diagnosis made sense. I replaced the sensor and the car seemed to be running normally on the 30 minute test drive. The next day my wife drove to work and she said the same symptoms had come back. It has been several weeks since I replaced the sensor and the CEL has not come back on. I have seen several postings about the spark plugs and wires and that is my next step. BTW the car has 94k miles.
Honda - Odyssey :: 2001 - Engine Hesitation And Feels Like Car May Die Or Stall
I have a 2001 Honda Odyssey with 140,000 miles. In the past year we've had major repairs to the car including rebuilding the transmission, fixing things on the steering column, replacing the catalytic converter, waterpump and timing belt, and a complete brake job. We thought we would be good to go for another 3 years on this van. But it continues to have this sporadic problem a few times a week: I will put the car into drive and press the accelerator, but the engine doesn't seem to get any fuel and it feels like the car may die or stall. If I keep my foot on the accelerator, the car will kick in and go after a few seconds.
A couple of times, I pushed down a little bit harder on the accelerator, but it sort of surged or jumped a bit and then got going just fine. My mechanic says this problem has to happen while he's driving it and has it hooked up to a machine or something in order to diagnose it and he is going to charge me more diagnostic fees to hunt for the problem. He says it could be many things. Is there something simple I can check myself in order to fix this before paying more fees? Would a different type of gas, or additives or a simple change of spark plugs be the first thing to try? We're tired of putting money into this van, but we feel we are invested in it now, and want to hang in there.

When I'm driving, steady mph, my car feels as if I've just downshifted, or that my foot slipped off the gas pedal. When this happens I've noticed that the tachometer drops down from say 20 - 30 to 10 or less! But just momentarily. It happens to a warm or cold engine. It's going to give me a whiplash! I've brought it to my VW dealer. They put it on the computer, and no problem comes up! No lights on my dashboard are on either. This problem is really annoying.
View 3 RepliesCamry :: 2007 LE - Exhaust Buzzing When Accelerating
I have a 2007 Camry le 4 cylinder. When under a load on the highway there is an occasional buzzing that occurs when accelerating (sounds like a piece of metal vibrating at a high pitch). It only happens under about 3000 RPMs and the noise doesn't occur any other time (idle, reving the engine while idle, slow speeds, etc.). Today I got it up on a lift and checked all of the heat shields under the hood and around the exhaust under the car. Nothing seemed loose. I had two mechanics look at it and one thinks that the exhaust flex pipe is the culprit, while the other insists that this is a known issue with the resonator (said a small piece may have broken off of a baffle inside and is vibrating). Are either of these components well known to cause this type of issue? I'd rather not replace both if one is frequently the cause.
View 2 RepliesCamry :: 2007 - Random Faint Noise When Accelerating
2007 Camry, I4, 156000km ... For some time now, when i accelerate i hear this faint pinging/rattling sound which sounds like its a pulley rattling or some sort of chain that is loose. It mainly happens when i start from a complete stop and even sometimes when i press the accelerator while cruising. I hear the noise more when the windows are rolled down and it sounds like it coming from underneath/front of the car.
I have changed the accessory belt and checked all the pulleys for tightness and they seem pretty tight, no wobbliness. I have gotten a dealer to check it out, and they told me it was the flex pipe, i had it changed and still hear the noise, this was quite a while ago. Also no leaks from the water pump area.
The sound can only be heard when the car is in motion, and if i put it in park, or N and rev the car there is no sound. I have heard that it could be suspension related and i have had a mechanic check the suspension and he says he cannot see anything wrong. I even tried to run premium gas in the car to rule out engine pinging, and sure enough the noise persists with 91 octane gas.
Could it be related to transmission? I do a fluid drain and fill every 30,000km. And the fluid always looks new and does not smell burnt. How I can get to the bottom of this noise?

View 2 RepliesCamry :: 2007 Making Noise From Rear When Accelerating From 0 To About 10-15 Mph
This is going to sound odd but here is the case: When accelerating in car from 0 mph to about 10-15 mph there is a noise coming from the rear. It sounds as if it is coming from the axial or something because it does it once every revolution. But the wierd thing is is that it does it louder when it rains or any moisture is in the air!
We had back right bearing replaced. But still makes noise. Don't think it is rock or tire because it only does it sometimes when speeding up. And does it very loud when raining or humid

View 5 RepliesVolvo :: Engine Bad Hesitation When Accelerating From Idle
A friend of mine has a 1989 240 I'm trying to get road worthy so he can sell it. After regapping, cleaning intake, cleaning idler, new sender, new in-tank fuel pump, and new MAF (all needed to be replaced) the engine still has issues accelerating from idle.
Did the usual diagnostics (#2, #6 LED flash modes). Even took apart the throttle body sensor to make sure that was functioning.
Idle is good and smooth. If I slowly open up the throttle the engine behaves well enough, but if I ope up the throttle to, say, 1/8th from idle the engine will hesitate POORLY. I can even make the engine die. I can drop the throttle to zero and rev back up fine so long the revs don't go down to idle. I made double-sure the throttle sensor clicks from the idle position (the sensor just has two spst switches to detect zero and high throttle).
Engine sounds fine otherwise. No problem opening up to full throttle once I get the revs a little above idle.

View 1 RepliesGolf IV / Jetta IV :: Hesitation / Bogged Down When Accelerating
I have a VW golf 2.0L AEG with 5 speed manual with 150,000 miles. Lately, it has been hesitating when I accelerate, not all the time but intermittently. It also shakes when I downshift, especially in lower gears. I have replaced the dog bone, the spark plugs, fuel filter, clean the MAF and tried another ignition coil. Nothing really worked. The only that worked a little (like a day) is when I disconnected the MAF sensor. I tried to do it again without much success. I scanned the car with VAG COM and I have no code.
The original clutch and original fuel pump are on the car. I checked the timing belt and it is in good shape. I was thinking that I may need a new clutch but I don't have nay slipping, just the vibrations when I downshift. I thought maybe the motor mounts are bad but I don't see excessive play when I rev up the engine. I sprayed the spark plug wires and ignition coil with water without any issues. What I should do next? Motor mounts or clutch? Bring it to VW for diagnosis?

Our 2015 es350 with 2,500 miles hesitates when accelerating from a dead stop, such as from a stop light. We are told this is to be expected with this vehicle. The dealership test-drove the car and say there's no problem. But this hesitation is unlike any other car we've experienced.
