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 ...
View 25 RepliesMy 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.
View 14 RepliesI'm noticing just the slightest 'hitch' in power delivery in second gear at about 1,500 rpm. My speculation is that this is the torque converter locking up.
View 14 RepliesI purchased a 2000 F250 7.3 4x4 (auto transmission) about 8 months ago. I've noticed recently that when I accelerate there is a slight hesitation like there is slack in the drive line. This does not happen when the truck is moving and I accelerate. There is not audible clunk and the hesitation is not in the motor.
I checked the u-joints and they all feel tight. There is a little slack in transfer case that allows me to turn the drive line slightly back and forth. Is this normal? Should I be planning on a transmission or transfer case rebuild soon?
Update: I was researching the leaf spring isolator pads (mine are warn out or missing) and it sounds like these can cause something similar to what I am experiencing. I am planning on pulling a 28' travel trailer from Colorado to Wisconsin next month and would like to avoid any issues if possible...... Obviously, I know ....
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.
View 6 RepliesThis 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.....
View 1 RepliesI 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.
View 8 RepliesI bought a pre-owned 2015 Sonata Limited in November. I only had less than two weeks before the car hesitated upon acceleration and the check engine light came on. At the time, I thought it was a loose gas cap as I'd just gassed up. I took it to the dealership, they pulled the code and it said to replace the accelerator pedal. That required a second trip to the dealership 2 weeks later when they completed the work. Two weeks later and the light came back on. I took it back and asked them to keep it until they found and fixed the root cause while I took a loaner. They kept the car about 2 weeks and when I picked it up, I found that no work had been completed. Two days (!!) later the light came back on.
View 11 RepliesI was just wondering if you all experienced a slight vibration of the car when stopped at a stoplight. I experienced a slight shaking of the car when I am at a stoplight especially feel it at the driver seat. I have about 300 miles on the car so far. Not sure if it is just part of the break in period? I only experience it when the car is stopped.
View 48 RepliesI have a 2008 ford f150 4.7 liter 4x2 & the problem I am having is when coming to a stop when I accelerate there is a slight shimmy in back end or could be described as a vibration for just a few seconds and then you don't feel it anymore until you come to a stop & restart. Once you have pulled off it will not do it anymore out on road. I checked fluid & it is not low in back end. Transmission shifts good so what could cause this.
View 2 RepliesI just picked up a Sport. I've noticed 1,2 quick stutter type thing happening intermittently at highway speed going up a hill. Dealer service probably won't be able to have it happen as it only has happened 3 times in my 400 miles.
View 9 RepliesI cant recall if these sounds were there when i first bought the car, probably because i have the radio on most times. I think the buzzing sounds were present in the last month at least.
After i start up my car and even after idling for a while, i hear a buzzing sound coming from the engine. It gets louder when I accelerate. When I let go of the gas, the buzzing sound lags for a few seconds and then quiets down a little bit, but still can hear it in the background.
I lifted the hood up to listen more closely. I am not totally sure, but i think i can also hear a faint hissing sound ( sounds like leaking air?). I cant pinpoint where it is, but its around the engine.
I also notice that when I am idle, the MPG number in the dashboard is dropping fairly quickly. Like 0.1 mpg every 20 seconds. This is new and started today. I last drove it 4 days ago and didn't notice it happening then and i watch the mpg very closely every time i drive. Could there possibly be some gas leak?
Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!
View 8 RepliesI ask this because when on the hwy (60-70mph) you can feel some vibration in your hands. I can let the steering wheel go and it won't move a bit but when hands placed on it you can definitely feel the road, including bumps, and regardless of road conditions. Tires where balanced at 7500mi but it still happens. Regardless of temperature or PSI in the tire.
I thought we had electric/electronic steering and no hydraulics? Maybe unrelated but, when turning in my driveway, very slow, I can hear a slight clicking (maybe rubbing) noise coming from the steering wheel column. Everything else has to be silent to be able to hear it.
Both of my bulbs flicker, intermittently. They will flicker, most times not at the same time as one another, for about 5 to 15 seconds then stop. I have not yet been able to detect a pattern. The battery is fully powered and the resistors are not throwing a code so I assume they are working (I installed them to eliminate an error code and stabilize the voltage). The capacitors (or "error eliminators") I have installed do not seem to do anything.
This problem just started recently too, they never used to flicker at all. The only problem I had is I used to get a bulb out warning but like I said I got rid of that by adding resistors. The bulbs are only 5 months old.
2008 Sonata Limited.
When I accelerate from a stop there is a metallic rattling in the engine compartment. My best guess is that it is near the middle and near the firewall. Can't see much under the hood in this area.
The rattling stops after about 60km/h or so and does not happen at all during cruising otherwise.
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 RepliesAny potential issues to the transmission if always shifting the gearbox to "N" when waiting at a stop light? I noticed the car idles a lot more smoother when at N so would I'm hoping to to do this regularly if it won't hurt the transmission.
View 5 RepliesWhen I'm idling my car at a stop, I notice a slight vibrating through the car... The vibration could also be felt through the steering wheel.
Not a major issue. Tried pushing car into neutral to see if it made a difference... Nothing.
I have a 2004; 4cyl Sonata, that jerks when I accelerate from a stop light or when I step on the gas, it jerks and sputters while passing another vehicle, then it gains speed?
