general problems of the 2009 Hyundai Sonata - part 1

Was driving on access road and the esc off light came on and the car started to stall- unable to accelerate. Had to pull to side of the road on wurzbach parkway. Took it to shop and had cam shaft, crankshaft sensors removed and replaced. Had $700 of other work done and car worked great for 2 weeks. Unfortunately today while driving home from esc off light came on and car was unable to accelerate. Luckily I got to safety but could've been killed if I wasn't so lucky. . . Pretty ridiculous problem to have especially as so many people are reporting the same problem. . .

Takata recall on July 27, 28 2019 the esc light came on intermittently causing the car to stall driving south on I 75 and later on the streets. After turning the car off and restarting the car it drove along ok. During our return trip, the car stalled again driving north on I 75 , and we pulled to the side of the road only seconds before a 18 wheeler passed us within less than a foot between us. All five us could have been killed. We were lucky to find a national repair shop opened on a Sunday who diagnosed the problem as a faulty crankshaft position sensor( the car has 54,000 miles ) . The part was replaced and after 4 hours we were on our way, minus $400 plus dollars. Research indicates that this continues to be an unsafe and potentially deadly problem -that this sensor must be recalled- and the public made aware of the danger.

The contact owns a 2009 Hyundai Sonata. The contact stated that the electronic stability control indicator illuminated while driving 60 mph. Also, the vehicle jerked and stalled, but was able to restart. Additionally, the accelerator pedal failed to respond when it was depressed. The vehicle was taken to several independent mechanics who referred the contact to heritage Hyundai towson (801 york rd, towson, MD, 877-387-5495) where it was diagnosed that the crank position sensor needed to be replaced; however, the failure recurred. The manufacturer was not contacted. The failure mileage was 113,000.

While driving, the esc off light comes on. It does so randomly, but frequently while highway driving.

While driving the esc and check engine light comes then it will only let me �coast� about 5mph.

My brake light stop switch broke into pieces with normal use so the brake lights stay on when car is turned off. My front brake hose sprung a fluid leak that made the brakes fully stop working in the middle of a drive. The front brake hose split and cracked prematurely cuasing the brale fluid to empty out. The brake pedal went straight to the floor without stopping the vehicle when this event happened during a drive. My esc light is on big probblem im assuming. My passenger air bag light is on as well both indicate are off and non working.

While driving normally, straight on a level road esc off light came on. Occasionally turns off but mostly stays on. Cars around 95000 miles and the same thing happened to a 2006 Hyundai Sonata I had around the same mileage. Mechanic said it was an electrical issue and need to call in an electrician.

Takata recall. I was told that the electrical module is defective by autozone,. We were driving down the highway when all of a sudden the engine light came on. We pulled over to check the usual stuff like oil and antifreeze and other fluids. But all of them were ok. We tried to leave again with no success. We had no power. The engine would turn over but when we tried to press the gas nothing would go. So we stopped the car waited for a while and then the car started. We countinued our trip carefully, but the check engine light was still on. After we arrived to our destination I went to autozone to check the problem. They said the eletrical and cpu modules are damaged. That of course has me a little worried. We have only had the car for a year so it couldnt be for that reason.

Esc light illuminates once the car is started and cannot be turned off by depressing the switch, this also seems to disable the cruise control.

The esc light comes on intermittently while driving. The car jerks as this happens. Once in this condition, the car runs extremely rough and will even stall when starting from a full stop (stalls in the middle of an intersection). During one occurrence, the car wouldn't go faster than 25 mph when going up a slight incline. I can't turn off esc; pressing the switch is ignored. If I turn off/on the car, the problem seems to go away for a while.

I have been experiencing a problem with my electronic stability control (esc). The "esc off" indicator lamp becomes illuminated while I am driving. I am unable to turn it off by pressing the esc button. When the esc off indicator is illuminated, this also causes the brake lights to not function, creating the risk of an accident.

The esc off light comes on and pushing the on/off switch does not put it out. If I shut the car off and re start, the dash light goes out. It seems like this usually happens going 30-40mph and I feel a slight jerk in the car then it comes on. It has also happened while driving on the highway around 60mph. The last time this happened was 07/12/17 driving around 30mph.

Esc light will come on at various times and engine will shut off. Will get check engine light intermittently with this but not always. This may occur going 20 mph on residential streets or going 70 mph on highway while driving in traffic. No rhyme or reason for it going off. May be dry or wet pavement warm or cold out. Hen engine dies at high speed may start back up upon deceleration or may need to make it to the side of road. Sometimes resets upon restarting the first time but other times it takes a few times of turning engine off then on.

We purchased a 2009 Hyundai Sonata from voss Hyundai in centerville, ohio on 5/21/2009. On 10/14/14 we took the car in for an �important safety recall� which stated that they changed the brake light switch because it could be defective and cause several problems, one of which would cause the illumination of the esc (electronic stability control) lamp among other things. Eight days ago our esc light and abs light came on and stayed on. I made an appointment and took the car to voss this morning only to be told that I would be charged $103 to even find out what the problem is, not to mention the charges for actually fixing a safety recall problem which I am sure would be expensive. I consider this to be a safety problem related to the previous recall work. They may have replaced a perfectly good brake light switch with a faulty one. This car has 12,875 miles on it and we only use it occasionally. It is in a garage at all times and this morning was the first time it has been out in rain. We had not bought a new car in many years and bought this one because of the great 10 year warranty on it. Apparently I should have sat in the showroom and asked to read the fine print on their warranty before buying it. I have researched this problem on the internet and many people are having the very same problem with all models of Hyundais. Several people have experienced stability and steering problems related to this defect in design or parts which could easily lead to an accident. We really liked the car until this happened, the dealership �not so much� now. I really think that Hyundai should admit that there is a safety problem and fix the problem correctly for the many owners who are having this happen to them, not just a $10 brake light switch after a $103 diagnostic charge.

Tl-the contact offs 2009 Hyundai Sonata. The contact stated that while driving various speeds, the "esc off" warning light illuminated and the vehicle stalled. The contact stated that the accelerator pedal would not accelerate the vehicle forward when prompted and that the vehicle loss power. Pacifico Hyundai of philadelphia, pennsylvania was made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000. Ad.

Esc light goes on and off intermittently sometimes engine hesitation is involved. This happens at varying speeds, varying operating temps, and varying weather/temp conditions.

The light turns on and you try to push the switch to it back on but it does nothing. This is the second time this has happened to me. The first I had some sensor replaced but its back on doing the same thing again.

When start the engineering and drive for 2-3 seconds, the esc off light will light and stays on, will not go off. I heard it had recall on 2006-2008 model for this, but not 2009models.

My esc & check engine light come on and car stalls and shuts off while driving on streets and the freeway.

My light keeps coming on and off on the esc not sure why or what to do.

While driving the car at a rate of 30 to 40 mph, I felt a jerk in the engine or transmission speed of my vehicle, and afterwords noticed my esc off light and engine lights had been illuminated and unable to be shut off with my esc switch. I also noticed that I was unable to rev my engine past 3000rpm's, consequently affecting my vehicle's usable power band and rendering me(the driver) unable to control the car's overall speed. After turning my vehicle off and then back on, the problem would go away, but only temporarily until I was again driving. I then went to a mechanic to have my car's computer scanned and found that there was a problem with my crankshaft or crankshaft sensor. My computer was then reset, but the problems persisted again shortly after.

The motor in the driver side window has gone out. When I told a cousin of mine who owns a Sonata said that hyundias are known for that problem, really!!.

Esc light keeps coming on and then going off. Happens on a regular basis.

Esc light comes on intermittently common problem with Hyundai. Previous recalls and current recall on some models. I am filing a complaints with national safety so that a recall can be extended to more vehicles. Hyundai is unwilling to fix these issues without a recall. Want people to pay out of pocket for something that is a manufacturing defect.

While driving on highway doing around 75mph esc off light come on. . .

Esc light on does not goes when using esc button.

Tl- the contact owns a 2009 Hyundai Sonata. The contact while driving the vehicle the stability control warning indicator illuminated intermittently. The contact stated they are able to turn the warning indicator off however the vehicle must be completely restarted. The vehicle was not taken to to the dealer to be diagnosed or repaired. The manufacturer was notified of the failure. The vehicle failure mileage was 115,000. Kh.

While driving at various speeds the "esc off" light illuminates for no reason. This has happened while driving on the freeway, normal surface streets, and has occurred while braking. Power steering goes out randomly during turns while on city streets or highways. Took the vehicle to a mechanic who tested the power steering and found no issue with the power steering pump. The pump is in good working order and did not need to be replaced. I had seen other complaints on the steering, with a recall issued, on 2008 and 2011 Sonata models, however the 2009 model was not included. This is very dangerous and could cause a crash. On those recalls the computer circuit board in the power steering control unit had become damaged and made the vehicle more difficult to turn possibly causing a wreck. Steering issue has been ongoing over the years.

As I was turning the corner from a stop sign, (I believe it may have been wet on the road that morning) I was not turning fast/sharp or hard; kinda slow because of the wet ground and how that road is, I slowly turned corner and then the light flashed on and I looked at my dash and then saw that the esc light came on and stayed on. I drove about another 20 mins to work and the light never went out. After I got to work, I cut the car off and the light went out, but later that evening when I was leaving work, it came back on and has been on ever since and today is Jan. 13, 2015. So it has been on a little less than a week now. Need some idea on what is causing it to come on and what needs to be done.

Esc off light turns on intermittantly. The esc on/off switch does not put it out. If I turn the car off and re start, then the esc off light goes out sometimes. Also, it returns when I start the engine next time.

The esc has turned off (dash light comes on) at various times. Previously my break switch was an issue and my cruise control would not disconnect by tapping the break. I had that replaced a few years ago. Now, the esc turns off after 30 minutes of driving. If I turn the car off, it is fine for about 30 minutes. Also, periodically, I press the volume adjustment on the steering wheel and it does the opposite . . . In other words, I press volume down and the volume actually goes up. The electronics seem to be very messed up. . .

The esc light has been going off intermittently in my vehicle for the past 2 weeks, causing the shifter to downshift instead of keep moving the car when I press the gas, and the gas pedal becomes unresponsive. This happened on the interstate (I-78) today, and I almost got into an accident in the middle lane. I researched the problem, and it seems there was a recall on previous Hyundai models, yet Hyundai has failed to address this issue in the 2009 Sonata. There needs to be a recall regarding this issue. It is very dangerous, and could be related to the crankshaft sensor or a number of things, but bottom line, it causes the car to become unresponsive while in motion, and the driver needs to pull over, shut off the car, and turn it on again for it to maybe work, maybe not. This is a horrible headache that needs to be addressed, and I am sure that I am not the only Sonata owner with this issue. . Read more...

Esc off light came on after starting engine when parked. I shut car off and attempted to restart engine. The engine shuddered and would not start. I turned off ignition and waited a few minutes. I again started the car , this time with no problem and the esc off light did not stay on. The esc off light has come on previously(once) and subsequently (once) at highway speeds with no apparent accompanying issues. I have taken it into the Hyundai dealer twice. The dealer replaced the stop light switch the first time but the light came on again (65mph). The second time in, the dealer checked out the car but could not find any problem as the esc off light was not on at the time of inspection. My research on the web leads me to believe that this is a significant safety issue . I am not driving the car out of town until I can rsolve the issue.

The "esc off" light was on the dash and remained until I turned off the engine. It was gone for a while then came back again often like every several hundred miles.

Esc off light comes on a few minutes after starting the vehicle. Resets after vehicle is shut off only to come back on a few minutes later. Additional sometimes cruise cannot be turned on and under no circumstances will engage with esc off light on.
