I have a 2015 sonata limited and it hesitates after a stop.

we are still having this happen but it seems like it's under damp conditions that it is worse!! we keep changing gas and noticed that one in particular - made it worse - so far we are sticking with buying the same gas and have less issues but still dampness seems to be the major issue!!

I have EXACTLY the same situation with my sonata 2015 eco model. i dont know what to do. Hyundai service center replaced fuel pump and do some other changes in electrical system. But in vain. i think this is some engine related issue :S

we were putting in premium gas and it seemed to help the problem but lately there isn't anything that is helping. But regular gas makes the car almost undriveable anymore. We need to take it back to the dealer again but not ready for the hassles we will have to go thru to get this resolved. I do notice that it runs worse in damp weather also!! Keep me posted if you make any progress and I will do the same here.

If you mean, from a complete stop, after taking your foot off the brake, there is a brief hesitation. It is there for a purpose. The hesitation allows your foot to travel from the brake pedal to the accelerator, without the vehicle rolling rearward. It's in your manual.

finally !!! i got my sonata 2015 fixed from the hesitation, stalling. Finally the hyundai service center got the error codes.they have replaced these 4 items. These parts are not expensive if your car is not in warranty, would cost you around 250 - 300 $. 1-Body Assembly Throttle ( EB25-01) 2-Sensor CKP ( CA14-03) 3-Sensor CamShaft POS ( MA10-21) 4-Sensor ASSY-MAP (BB05-02)

Yes, my 2015 Sonata does this also. Sometimes the stall is worse than others. I have put it in the shop 3 times, but each time they tell me they cannot find a problem. Sometimes the stalling is worse than others...it is a very serious worry.

@linda Please follow my advise,i was having same problem as of yours. Please ask technicians or service center to replace throttle assemly/censors and the parts i have mentioned above. your car will be fine.

Thank you. I will forward your response to the technician at the body shop....I'm not sure he will listen...but, I told him I would send him a link to this page. I am going tomorrow and see if I can trade it in for something else....it is really not safe...I have pulled out in traffic on Hwy 90 by my house and it was almost scary...thank you again

This just happened to me, my engine light went on and then car buckled. Thank god we have a good frien who is a mechanic and did the test showing the manifold stays open causing this He left the light on so the dealer will see and my car has only 16, miles.

Mine is really bad. If I slow down to make a turn there is a bad hesitation for a couple of seconds when I step back on the pedal. I can't stand to drive it. The dealership very aggressively says that it is driving fine. I will never buy another Hyundai. The car is beautiful and I really like it in every other way. It may go several days without issue and then goes back to doing the same thing. I've tried different gases it doesn't matter.

Did anynone got this problem fixed?

I bought my 2015 Eco Sport from Nissan dealer 2 weeks ago. Noticed the hestitating start and a couple times at stop signs and a drive thru it felt and sounded like the transmission fell out of the bottom of the car when I tried to drive away. The local Hyundai dealership said the software may need updated or a reboot to the computer system. My appointment is in two days. I found this online after researching what he told me. https://www.cars.com/articles/2015-2016-hyundai- sonata-software-issue-1420684339760/

Mine has stopped hesitating and has been driving fine for a long time. I don't know what caused the improvement but it just doesn't happen now. I drive with 2 feet and occasionally I don't get my foot off of the brake quickly enough when turning a corner or in tight traffic. It will not accelerate if your foot is not completely off of the brake. I can't blame the car for that though. I am very happy with the car now.

Its the TCS that's why it happens more when its raining you need to slow down and accelerate from s dead stop slowly or you can turn off the TCS and spin your tires when you take off from a red light.

I had a recent problem which sounded like yours. My service advisor fixed it in 3 seconds. This may or may not be your problem, buttttt I suspect it is. It was me; not the car. I sometimes drive with both feet. One on the brake and one on the accelerator. That confuses the car and it always errors to the brake. Once you get your foot off the brake it will be fine. Try using one foot for the brake and the accelerator and let us know if that fixes your problem !

I have read everyones post here and I have been to the dealer 6 times yes 6 with my 2015 Hyundai Sonata Eco so I have the same hesitation & stalling issue as everyone else in here and it started around 20,000 mile. I have had every computer update Hyundai has and still no fix!! The problem is this vehicle has a 7 speed dual clutch and in between idle and 1st gear it loses power cuts off also dies at a stop while idling. This transmission is garbage and it stresses the engine which causes the loss of power. Keep fighting with Hyundai as I am because I will make sure this issue becomes a recall I bought a lemon!!!

I had a 2012 sonata limited, after driving through heavy slush I would stop at a stop sign, and as soon as you stop the car just starts shaking, until you give it gas then it stops. I now have a new sonata, and this sonata does the same thing, just not as often as the older model. It's like dampness gets into the tranny or on wires or something. Who knows, but I put 300,000 kms on the 2012, never once had a problem with anything other than the sunroof. No lights on the dash even!

I think I’m having the same problem.. I stopped at a red light Halloween night.. it jerked and then wouldn’t let me move anywhere , my radio said “Battery discharged” then where my mileage is it said “check break” I’ve only had this 2015 Hyundai Sonata hybrid for a year now & they said it’s odd that the hybrid part won’t start up.. anything on this I should know about??

Car also says OFF it suppose to say “READY”
