Sonata I45 (YF - 2011+) :: Loosing Power While Driving - No Response To Acceleration
Oct 16, 2015
I have a Sonata 2012 limited version. Lately its been loosing power while driving. It will going around 60 for instance and as I am pressing the gas all of the sudden the rmp begins to drop and the car doesn't respond to the acceleration of me stepping in the gas. It is not until I completely get my foot of the gas and re-engange again that it will recognize it and continue accelerating. It will doing whether I am going 60, 40, 20 mph.

I have been getting no throttle response intermittently. I will be driving usually at lower speeds and all of a sudden the engine with slow down and there will be no response to the throttle pedal. It will come back quickly. Also the ESC light sometimes comes on and yesterday I could not set the cruise control. Today it had this problem but the ESC light was off and cruise control worked.

I purchased my Prius in late September of last year. I never had to run the A/C at the time before winter came along. The car has 102,000 miles on it when I purchased. It has run great and I really can't complain as I've put another 10,000 miles on it.
Last week during the hotter part of the day (3:30pm at 93 degrees) I pulled out of a small parking lot and pulled forward 25 yards to a stop sign. The car literally lost all acceleration as I pulled away from the stop sign. My A/C was running at the time. There were no red or orange exclamations on the dash. It just wouldn't go anywhere. I hit the stop button shutting off the car.
When I started again there was still no acceleration and the hybrid battery fan was working overtime to move air. I turned off the A/C, parked for a moment to the side, stopped and started the car, it started to move but was sputtering a little. I was only getting power from the gas motor even though I had 4-5 bars on the hybrid battery. The hybrid battery fan was still running high as I went down the road. I didn't turn the A/C back on and instead rolled down my windows.
Now we move to yesterday where I drove the 15 or so miles home from work (90 degrees at 3:30pm). My wife hopped into the car and was heading back in town when suddenly on the freeway she lost all acceleration and coasted off the next freeway exit. She shut the car off on the side of the road and waited a short while. It again had some sputtering but she was able to drive back home.
Similar scenario today. Left work around 3:30, a/c was on, temp around 87, plenty of charge on the hybrid battery. I make my usual little u-turn before backing into my space in front of the house. When I placed the car in reverse it again lost all acceleration power. The radio doesn't turn off, I still have dash lights, etc.

The owner of the car claims that there was sudden unintended acceleration, and it was 09' Sonata.
Video .....
I thought this should be very concerned to us, since we all drive 11' sonata & up. I heard Hyundai installs some kinds of system to prevent this incident to all cars manufactured after May of 2012.

So I noticed, driving to work today, that there was this loud squeak happening while accelerating. It almost sounds like an old belt, or how old brakes sound when they are to worn. I have no idea where this sound is coming from.
The only thing is it happens ONLY when the RPM's are 2k-2.5k. And ONLY while accelerating. Other than that it doesn't make that noise.
I've tried revving to see if the noise is there. I also tried while moving, to hold the clutch and rev match to that zone and still no noise. It only happens while in gear it seems.

Driving to lunch today I pulled out on the highway and accelerated hard. The Sonata didnt want to shift higher than about 4th gear (auto trans w/ the "slap stick" that comes standard. I laid off the gas and the car seemed to be running fine at that point. 1/2 mile down the road the car just died. I pulled over the car restarted fine. At this point it didnt want to shift well and died a couple times. I stopped for lunch. Afterwards I took it easy, car acted fine. Outside of work I accelerated hard again and the same thing started again.

Eco/Normal/Sport S/S+ Mode... the literature doesnt say much except it changes throttle response and power output. For the Sport modes it says that "The rear-wheel drive IS 350 F SPORT's Sport S+ mode also tightens the suspension..." Are the shocks somehow adjustable, or is this just marketing BS?

I've had my car almost two weeks, but today is the first time I've driven it with the radio off. I noticed some ticking coming from the engine during acceleration, and maybe it's my imagination, but it seemed more pronounced with the ECO mode turned on. I know these GDI engines are supposed to tick at idle, but is it normal to hear it during light acceleration too? My oil level looks fine.

My 2011 Sonata 2.4L GDI has already 76k miles. Spark plugs were replaced around 75K miles, Air filter was replaced. Fuel treatment was done several time since ownership, Intake CRC for GDI was used once about 2K miles ago. The car is doing good until recently. When I accelerate the car acceleration goes uneven. It is not like hesitating but you feel like the car is taking it in steps. Sometimes the first run in the morning, the car idle feels a little bit rough but that's only in the morning. It has been like that for a month now. What do you think it can be? No Check engine light, no pending codes and nothing major except that. I really suspect a bad upstream oxygen sensor (Air fuel ratio sensor). What do you think?
A look through the intake shows a very clean intake. No signs for any carbon deposit. A Hyundai dealer checked the car and told me there is nothing to worry about. Just told me to buy more Hyundai fuel treatment (AKA Chevron Techron) which was done and still I feel uneven acceleration.

I have a 2011 GLS with about 47K.
There seems to be an issue with acceleration around 50-65MPH as the RPMs will jump as if to hesitate between gears (just my assumption). Maybe driving style/conditions as I live in West-Central Florida?
I'm the original owner and we have two of the same vehicles.

I noticed twice yesterday when I was accelerating from an intersection, going into 2nd gear (or 3rd depending on how short 1st is) it feels like it slips into neutral and I lose acceleration. If I take my foot off the gas and coast for a moment then re-apply acceleration, it goes on as normal without any problems.
66k miles... Owned it for 2 years and have had no other issues and have only taken it in for oil changes.
Am I correct in assuming the ATF is supposed to be good for the life of the vehicle?

I recently purchase a 2011 Sonata. It sounds like there is a rattle in acceleration coming from the exhaust (passenger rear)
I had the just alignment professionally checked, and it's spot on, but it seems to pull to the left still.

I have a 2014 Sonata with 22k miles. I love this car but lately I've noticed valve rattle under acceleration. Brought this up with service tech and he said I'm not driving the car on long enough trips to keep it cleaned off. When I researched the GDI very little info comes up for Hyundai mainly vw and BMW. I guess what I'm asking is is the only fix for the carbon build up removing the intake and cleaning the valves manually or is there another way.

11' Non-Turbo 2.4 with 145k Full Synthetic every 5k (Done me or provided to the quicky lube) Around 80K about 2 weeks after taking it in for an oil change my wife heard a ticking sound coming from under the hood. Pulled over and there wasn't a drop of oil on the stick. It started with about a qt every 1000 miles or so, now it's to the point that I have to put a qt in about every 3 days (1-200 miles)
We cannot see oil anywhere, last I checked the plugs had carbon build up but were not wet. (Recently) We also hear a ticking sound during hard acceleration and a good bit of black smoke coming from the exhaust.
We still owe 5k on it, it's our first new car and I'm terrified the thing is going to blow up before I pay it off. Tonight as I was about to get in the car with her I heard the clicking sound again but this time it was full (just added some yesterday). I have compression and leak down testers, know a little bit but I am nowhere near a "mechanic".

When the engine is cold, and up to about half way to 190 degrees on the temp gauge, the throttle seems to not want to open very far. Almost like there is a disconnect between your foot and the throttle. You get a little acceleration but no where as much as when the engine has warmed up. I have noticed this when the outside air temp is below 25 f or so. Is this some goofy emissions or "save the motor until its warm" thing?

I have a 4motion Automatic Tiguan 2011. It always had a tiny acceleration lag which I believe is quite normal. But lately, our Tiguan developed a that-doesn't-sound-right symptom. I feel the acceleration gap is much longer now, the engine makes quite a bit of noise but the car hesitates to go, and it gets a bit worse on uphills. It had a transfer box leak that was fixed 3-4 months ago.
It sounds like a transmission problem to me. Is there something wrong with the power train?

Last week I was losing pressure on my left rear tire. It turned out to be a 3 inch spike that was bent inside the tire. The tires are the original Goodyears with 37k miles on them. I decided to replace 2 rear tires with Yokohama YK580s and turned the extra Goodyear in to a full size spare
Question. At high speeds 50 plus the rear feels like it's sliding a bit if I barely move the steering wheel. Having issues with 2 different tires.

I have a 2011 Sonata Limited. I have issues with the gas gauge. At times when I start the car I can literally watch the fuel level go all the way down to Empty and the low fuel light will go on. I can leave the car running for a few mins then it will go back up. I can also be driving and the gauge will go up and down. I have gotten to the point where I just reset the trip counter and monitor the miles that way.

I have sonata GDi model 2012 ..the engine is always knocking during driving the car ..I changed the spark plugs, Fuel pump, cleaned throttle as well..some of my friends said it could be about octane range (IKA) but I put it a high quality of gasoline ( premium) and still knocking. There's one thing I haven't checked yet ,is ( injector nozzle) ..
