Santa FE SM (2001-06) :: Slight Hesitation During Acceleration Suddenly

Last night i noticed a slight hesitation during acceleration. Today i had driven around in town for awhile and did not notice any hesitation. When i got onto the interstate I pushed down the peddle to pass someone and it did nothing, I let off the gas and back on and the car bucked pretty bad. All the way home it has issues when I pressed on the gas but did fine at cruising speed. I would think a fuel filter would have been a slow progression issue so I am thinking maybe it is a sensor. I sprayed carb cleaner around vacuum hoses today and did not notice any surge so I think I eliminated a vacuum issue.

Accent RB (2012+) :: 2015 - Engine Hesitation / Bucking At Low RPM

Searched but did not find. Just bought a 2015 Accent hatchback. Only issue I have had is a lean bucking of the engine if you don't have enough throttle (RPM). From a standing start, the auto trans will shift from 1st to 2nd to 3rd very quickly if you are going real slow. I have to give it at least 1/4 throttle and accelerate quickly to keep the trans from shifting too soon. So far I have 2000 miles and 1 oil change, running 93 octane gas. Is this condition normal?

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.

Camry 2012+ :: Roll Back When On Slight Upward Hill?

I have a 2012 Toyota Camry and I noticed that when I am on a slight upward hill, my Camry will slowly roll back if I don't have my brake pedal applied. Does this happen to you and is it normal? This is my first new car and my old car which was a 94 lincoln never did this even on very steep hills.

Prius (2010-12) :: Slight Hesitation At Slight Acceleration Or Constant Speed

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.

Accent RB (2012+) :: ECO Won't Come Back On

So, I just got home and turned off the ignition. I then accidentally clicked off ECO. When I went to press the button again, it lights up and it does on my dash as well, but once I let go of the button, they are both off. I thought this had something to do with the car being off, so I started it and I still couldn't get ECO to go on.

Am I doing something wrong or is it possible that the button is broken?

Accent RB (2012+) :: 2015 - Slight Click / Tap Noise Coming From Rear

When I'm driving and come to a stop for at least two seconds, I hear a slight click/tap noise coming from the rear of the vehicle. Then as soon as I let off the brake, I hear the noise again. I can only hear it with the radio off, and I cannot seem to replicate it when my AC is running. I have Eco mode enabled too. I have no engine/warning lights on my dash, and have no reason to believe my vehicle has an issue; just simply trying to find out what the noise is.

Accent RB (2012+) :: Knocking Metal Rattling Sound When Accelerate Up A Hill Or Slight Incline

Since about 5000 km, I have had a knocking metal rattling sound happening when I accelerate up a hill or a slight incline. It has happened a few times on flat road as well just more prevalent on the uphill battles. Now I assumed it was jus something loose that was rattling since I installed a cold air intake and had installed hid lights(I thought the ballast was banging on something). I tried and tried to find the rattle but I had no success. I read up on here about other people suffering the same problem and that running higher octane gas would solve it well I tried 89 and it was still there just not as much and I recently started using 91 and its gone haven't heard it at all.

Accent RB (2012+) :: Car Makes Cooing Noise In Back

My 2011 accent hatch makes a coo like a dove when I turn it off sometimes and it sounds like it's coming from the boot. I actually did open it to look for a bird one day. It's a diesel, and I did have a problem with algae in the fuel which was half fixed..

Acceleration :: Car Sort Of Jumps Back And Fourth While Driving Uphill

Not sure if this is called "sputtering" or something else. But essentially today all of the sudden my car would sort of jump ahead, as if I when revving it back and fourth on the pedal aggressively. Not sure what could have caused this. Today was an essentially cold day so that may have something to do with it. Also my car overheats so I have to put anti-freeze in it most days. For the last few days I've been just using plain water, could this be the culprit? Why is my car jerking around like this?

Accent LC (2000-05) :: Speedometer Needle Jumps All Over The Place

When the weather is rainy or just very humid, the speedometer needle in my 2000 Accent jumps all over the place. According to the service dept. at my local dealership it is most likely the speed sensor causing the problem.

Elantra XD (2001-06) :: 2002 Gt Idling Very Rough With Rpm Jumps Back And Forth From 1500 To 2500

My wife drives a 2002 Hyundai Elantra GT. Recently the car started idling very rough with rpm jumps back and forth from 1500 to 2500 rpm. The check engine light came on and threw a code for the IAC. I also notice a clicking sound coming from the engine and I can see sparks arching at the coil/plug wire. The arching is happening at the coil with the numbers 1 & 4.

The car is difficult to drive. It shakes and surges and isn't pleasant to drive at all. These issues started happening very recently. The car ran great up until now. We've stopped driving it for the time being until we solve the problem.

We had the car serviced a few years ago and they changed the IAC and mentioned something about a gray wire that we should watch out for.

I'm not really sure what the issue is. I don't know if it is the spark plugs, wires, or coil. Or it could be the IAC or something else. I'm comfortable working on the car myself, but I would rather not try fixing many things if it is just one thing actually wrong.

So far, the only thing I've tried is to spray some carb cleaner into the throttle body towards the IAC in hopes that it would clean it and solve my problems.

Where the IAC is located. I want to try remove and clean it, but I'm unsure of exactly where it it. I know it is somewhere on the throttle body or intake manifold, but I'm not sure exactly what I'm looking for.

Prius (2010-12) :: NAV Screen Jumps Back To Map Display After Finishing Audio Transaction

Just picked up my 2012 Model Five w/ ATP. Love it (more details to come), but it seems to require too much touch screen action that could better be accomplished through voice recognition. The nav screen always seems to jump back to map display after I've finished an audio transaction. Any way to just keep the audio screen in place until I select the map display? I don't like having to go back to audio to change stations. Also, the nav voice instructions are sometimes only useful for part of the trip. Is there any way to squelch the voice while driving without going into setup and using the touch screen? Answers are probably in the manual but I haven't found them so far.

Accent LC (2000-05) :: Gear Shifting - RPMs Instantly Jumps Up

I have a 2005 Hyndai Accent GT automatic (83,000 km) and I am having a problem with the gear shifting. It's happening more and more.

As I am driving I am pretty sure that it's changing to a higher gear but when I slow down it seems like its not shifting down at all. Coming off the Highway I have to slow down and when I speed back up it seems like its still in the high gear. The RPM's instantly jumps up.

The only way it fixes it self is when I pull over and shut off the car and then start it up again and I am fine. A friend at work said that I may have to have my transmission fluid checked and filled up.
