Elantra MD (2010-15) :: Loss Of Acceleration Suddenly While Still Pressing On Gas Pedal
Mar 11, 2016
My Hyundai Avante (2011 model 1.6) suddenly loses acceleration while my foot is still pressing on the gas pedal. Every time that happens I have to raise my foot from the gas pedal and press it again to make the car accelerate. This thing happens randomly, but mostly at speed lower than 80 Km/h
I tested the car on an empty road once; I didn't raise my foot from the gas pedal this time when the car lost acceleration. The car speed dropped to zero and the RPM gauge returned to idle (i.e. around 1000 RPM).
The check engine never light up during or even after this thing occurs. Here is the list of things the mechanic tried on my car:
1-Cleaned the body throttle
2- Tested the car with another used body throttle
2- Tested the car with another used gas pedal
3-Check the fuel pressure and injection
4- Checked the sparks
5- Tested the car onboard computer.
None of the above worked!!! Here is the strange thing my mechanic discovered, if he unplugs the cable of the Anti-lock braking system in the car. The problem never occurs.
I have been driving the car for two weeks, with the ABS system unplugged. The loss of acceleration problem never happens. I am not sure what the ABS has got to do with the car acceleration.

My 2003 Elantra has multi spark (quad) electrodes? I have a hesitation on acceleration problem. Also feel resistance when pressing the gas pedal. I am going to change the plugs and wires. Just wondering if the type of plugs may contribute to the problem.

When I so this its like pressing in the clutch and revving it but my car is an automatic. During the upshift and downshift there is no jerking or hard shifting so I would assume this is OK? And is full throttling your car every few days bad or good?

2001 F150 V8 4.6 Liter... I've been experiencing hesitation when first pressing the gas, stall at idle, RPM fluctuating between 1000 and 500 at idle and loss of acceleration. Had the truck read at autopart store and received a P0402 error and misfire is cylinder 8.
At this point, I've changed the the plug, COP, EGR valve, EGR Valve Solenoid and DPFE sensor and still have the exact same symptoms. I've also changed the plug for cylinders 5,6 & 7 as well. The check engine light is on, went off briefly after changing DPFE sensor, but back within a day.
Given the fact the error code is P0402 and some of the threads I've read, I thought the issue was centered around the EGR system, but I've replaced many of the components.

I have manual shift and the clutch is worn out. when in motion if I press the pedal the rpms jump but the car does not accelerate. only way to accelerate is to press very gently.
Q: do I always need to change the flywheel, which is expensive or changing just the clutch will do??

My 2013 RX350 (all-wheel) has a super annoying droning sound when pressing gas pedal - it is not the smooth-humming but a kind of low cat-purring sound that is more pronounced when in low RPMs. The dealership can't tell the problem, Lexus Field Specialist acknowledged the sound and said I am not the first one to complain about it, but he doesn't think anything wrong with it. According to him, this is not the sound of the engine, but the exhaustion system. My overall experience with RX350 is not as good as I had expected: it is nosier than my previous highlander, it is also nosier than my wife's Odyssey.

I have a 2001 Elantra with 126k miles. For months it's been randomly hesitating, meaning I'll be riding along and suddenly the gas pedal will do nothing...then about 3 seconds later, VROOOM, the gas pedal will start working again. Recently, it's started stalling as well.
I've already replaced the MAP sensor, input speed sensor, throttle position sensor, spark plugs, wires, and coil pack. Nothing has worked, but it is getting progressively worse (it stalls more frequently, and the gas pedal becomes suddenly unresponsive more often).

I've noticed when encountering a moderate hill at 60 mph in cruise the revs might suddenly increase from 2200 to 2700 rpm, then back down slowly as I crest the hill. If I'm in manual mode it stays in 6th gear, but almost feels like a downshift. I also feel no accelerator pedal movement. Is this a two stage intake at work?

So my 2005 elantra 2.0 CVVT has 189k on it 1 owner.
I got a check engine light one day and i read the code. Came out to be 02 sensor code bank 1. So i order a denso o2 sensor and replace the part.
I drive the car for about 400 miles to reset monitors and get a check engine light. P0420 cat code. At this point the car drives with normal power and pickup.
1000 miles later my car has lost power. It doesn't have any get up or power when driving normally. I take the car to my local shop and they recommend replacing front cat. I replace front cat, same issue.
At this point i'm not sure if it is a transmission problem or maybe my 2nd cat or something else?
On the freeway if I put my pedal to the ground the rpms surge up very very slowly,
Also seems like the car doesn't shift till around 4k rpms, seems like previously it shifted sooner.

I have had my 8 month old Prius for a week. I have used cruise control fine before and after the incident. All of a sudden we started slowing down. Doing any thing on the cruise control had no effect. I canceled it. But every time I pressed the accelerator I just got the amber warning light come up and the car beeped at me and no acceleration. The cruise control didn't get the car going either. I had to stop on the motorway. Put the car into park then put it into drive and drove off fine and the car has worked fine since.

While driving to work this morning driving about 25 MPH and increasing speed gradually in traffic the lane I was traveling came to a sudden stop, I slammed on the brakes, ABS took over and I steered around the stopped lane of traffic with no issue. Here comes the problem, I never stopped rolling and traffic was coming up behind me in the lane that I just went in to and I stepped on the gas pedal and got nothing, truck was running, no lights or warnings just a dead gas pedal. This only lasted maybe 5 seconds and then it went but it was totally dead no matter how hard I stepped on the gas and vehicles were beeping at me from behind me. It finally went (5 seconds seems awful long when cars are approaching fast from behind) and it drove fine from there on. I guess I plan on trying to recreate this issue but thought maybe there is something with these trucks that caused this that I don't know about?

I was driving my 2010 Prius on the Highway (less than 2 miles) and the engine check light came on.... shortly after the ! (triangle with exclamation light came on and then started flashing). I exited the highway and was going back home. On the way home, I noticed a decrease in acceleration and then a message 'Hybrid...'
I was able to coast into an apartment complex and then got a ride home.
After about a couple of hours, I went back to the Apartment Complex. I reviewed the manual and one of the options was to check the gas cap. I filled the tank up last weekend and haven't driven it since today.

I've been having a problem over the past month with my base 2014 Elantra (33k miles). Sometimes when I go to start the car there is a complete loss of electrical power. One of a couple of scenarios will occur:
1) Key Fob will not unlock/lock doors:
*There is no power to anything (no dash lights, interior lights, car won't crank).
2) Key Fob will unlock/lock doors:
* Either all interior lights will be on and when I attempt to crank everything shuts off (no dash lights, interior lights, etc)
* Or Clock and radio are reset, car starts fine
* The battery checks out as far as voltage/charge.
* There are no visible fuse issues.
* There are no check engine lights.
I have had it in the dealer the past 4 days and they haven't been able to reproduce the issue. So far I have been able to eventually get it to start by opening and shutting doors, which would lead me to believe it is a loose connection somewhere, but again the dealer hasn't been able to diagnose anything.

My Legacy sedan is not behaving well. On more than one occasion, when pressing on the accelerator, the rpms do not rise. I put it in park and try to press gas pedal, nothing. Turn the car off and let rest for a few minutes, then start it up again, and it's fine.....

My 2014 Elantra Limited Automatic 1.8 has just developed a problem tonight. I was backing up my driveway, when the car began shaking, making a grumbling sound, and felt like it lost power for a second. I pulled out of my driveway and tried backing up again about 5 more times, and it kept on repeating the problem. The car was leaking what appeared to be a clear fluid which stained the garage floor. It drives fine going forward, and only has 4,000 miles.

So for reason irrelevant, at about 500 miles on the odometer, I drove the Prius quite hard the past couple of days. In retrospect, a poor decision as I am now all kinds of concerned as to what kind of damage I may have done. I know break-in is said to be 600 miles so I was below that. I'll describe my 'hard' driving as heavy acceleration, often pedal to the floor, a few hard stops and umm excessive speed (we'll leave that up to interpretation). So I'm just stressing about it now.

The car starts if I press the gas pedal slightly. It falters a little and idles a little rough, fuel can be smelled in the exhaust after the startup (not afterwards). Once the car starts it drives just fine. The guy who sold me the car informed me that he ran the car to empty tank two days ago and had to fetch 2 gallons in a can to start it again, that is when the problem started.

While driving the other day, the truck suddenly began to stall when pressing the accelerator. The water in fuel light came on as did the glow plug light. This continued with the truck sometimes dying all the way and other times just stalling then picking back up. No difference in throttle pressure seemed to make a difference except that letting off totally then slowly pressing seemed to let it keep running sometimes.
So I get home and drain the fuel water separator. I gets about a thimble full of water and lots of the rusty looking junk others have talked about. Try to run the truck again, same thing as before. I then changed fuel filters and thought that had it licked but after about 10 minutes it started again. By the way, the 6mm plug seemed to have about a third of the threads rusted off. Not sure what that means as I drain it at least twice a year.
I have read a lot about the ICP and IPR issues and was wondering if this could be my problem. I am hoping its not the HPOP. My other thought was something in the fuel tank blocking the in tank filter. I checked the top mount bowl and it was only about two thirds full after running the truck

Having issues with a 2014 shutting down. Was at a stop light the other day and car completely lost power and shut down. When this happened oil, engine, and battery light came on. Once I parked car and turned off, it restarted. The dealership acted like I had no idea what I was talking about and would like to have some information when I take it back to have this problem corrected the car is not even 2 years old and has 30,000 miles on it.

Getting a clunk feel and sound while pressing the brake pedal? If I press harder, another clunk or two occurs. Felt and hear especially at low speed or stopped. No issues braking, but the clunk has slowly gotten worse since I dropped the car on RSR Downs which could be a coincidence.

When I start the car in the morning & step on the gas there is a fluttering noise which happens each time I accelerate until it warms up. I bought the car with 17,000 miles on it and I didn't notice it happening then, but it was warm weather then.
