On five separate occasions while driving on the highway the vehicle will loose power and ability accelerate with a flashing engine light. These incidents have almost caused me to be rear ended three times because you are not able to accelerate above 60mph in rush hour traffic on a busy interstate and the ability just stops quickly with no warning. The vehicle also has been having the rpms drop to 0 and shoot back up while braking, and while driving it is tough to accelerate and then you will feel a noticeable 'kick' and the rpms will shoot up drastically before it will accelerate. I have had 2 software updates done, a new wire harness, knock sensor cleaning and a knock sensor replacement. The engine code is always the same 1326.

On 2 different days the car killed on the highway. Both times the hyundai service dept. Looked at it. The first time, they said the software update that was worked on a few months previous, had a glitch in it. The second time they said they didn't know why it happened. While driving the rpms will race up but the car doesn't move much. They said it didn't do that when they drove it. Also since the first software update was done , if I drive 80mph (on the interstate hwy.) the seats shake.
June 2019, at about 11,500 miles took car in for an oil change and was told due to a recall, a software update needed to be done. At about 13,500 miles, engine light came in, car was jerking in motion on highway and lost power. Car would not accelerate last 62 MPH. Car was serviced and block sensor wire harness was replaced. Car was returned and again while in highway engine light came on, lost power, car was jerking while child was in the car and while car was in motion. Car was serviced and block sensor was replaced. At about 18k miles, engine light came on while on highway and again with child in the car and car lost power and also was jerking while in motion. Car was serviced and engine replaced. 3000 miles later, again while in the highway, engine light came on, car lost power and was jerking and would not accelerate. Car was serviced and the following day, while on the expressway in chicago, the engine light came on and the car lost power and was jerking hard while in motion. Car was towed to dealership in rockford il. After the 4th attempt to repair, lemon law claim was filed with hyundai motor america which they denied due to mileage. This car is unsafe to drive. When it loses power there is no warning, no brake lights come on to notify cars behind, and while in the busy expressway in chicago was very dangerous. Also dangerous to have children in this vehicle. Hyundai motor america refuses to do anything but repairs and is ignoring the dangerousness this problem. This occurred all 5 times while the car was in motion. The code that reads for this is 1326 per the service records.
Tl* the contact owns a 2018 hyundai sonata. While exiting the interstate at 60 MPH, the vehicle went into limp mode, jerked, and failed to accelerate. In addition, the check engine warning indicator illuminated. The vehicle was towed to auffenberg hyundai (located at 1300 central park dr, o'fallon, il 62269, (618) 622-9001) where it was diagnosed that the nox sensor failed and needed to be replaced. The contact stated that the vehicle was repaired for the third time. The contact also stated that the technician reset the computer, the wiring harness was replaced, and the nox sensor was cleaned; however, the failure recurred. The vehicle was also taken to an unknown dealer in tx, but the failure code could not be recreated. The dealer reset the computer and replaced the nox sensor, but the failure recurred. The manufacturer was notified and provided case number: 15894913. The approximate failure mileage was 15,000.
Tl* the contact owned a 2018 hyundai sonata. The contact was alerted by the police and fire departments at 4:00am that her vehicle caught fire. The vehicle was destroyed. The fire department extinguished the fire. A police report was filed. The contact wanted to obtain a fire report to verify if the fire originated from the engine. The insurance company was not notified. The contact later received notification of the manufacturer's service campaign number: 953 (ECM & cluster update-engine monitoring logic product improvement). Rogers auto group chicago (2720 s michigan ave, chicago, il 60616, (312) 620-1340) was contacted and was waiting for the manufacturer to provide guidance within 48 hours. The manufacturer was notified. The failure mileage was not available.
On friday, may 31, 2019, while driving home from work, I noticed my vehicle began to shake while driving. (car has 14k miles) I called gossett hyundai at covington pike and was told it was probably a rotor or a spark plug and to bring it in saturday morning. Saturday morning, while driving to the dealership, the bluelink lit up saying my car needed to be serviced. I drove the vehicle to gossett hyundai at mt. Moriah. After going back and forth (in front of the tech) they agreed to run a diagnostic (because I told them I was worried about driving my car to the covington pike location), and the tech informed me that he was a tech and he could run the diagnostic. After running the diagnostic, I was told that one of my cylinders was not firing. After some period of time, they located an ignition coil in the parts room and replaced it. The car still was not running correctly, I was informed that the car needed a spark plug but they wouldn't have one until tuesday, june 4, 2019. After the dealership received the spark plug and installed it (I guess?), the car was still shaking and not running correctly. Sometime june 5 or 6th, they called hyundai manufacturing and have been receiving instruction from the manufacturer directly to run leak tests. I was informed that they also used a camera to look down in the cylinder and that it has 'scarring' which could be from fluid getting inside? I have also been told that it is probable that my car will need a complete new engine. It has been 2 weeks and the dealership is working closely with the manufacturer to see what needs to be done.
Driving and engine light started flashing and I could not keep up with the speed limit as the car would only go about 20 MPH. The car says "possible condition with your engine control system has been detected" car was in motion on city street.
I purchased the 2018 hyundai sonata 2.0t on 8/27/18. After we were able to experience different driving conditions and situations, my husband and I noticed that (1) at night, while driving on the highway, the windshield appeared very dark as if it was heavily tinted,and making it difficult to see the road. (2) when driving on highway or road, with normal beam headlights, we noticed that the line of demarcation from headlight to dark road was very close to the front of the car. The reason given by the maintenance dept was that this was so cars in front wouldn't be blinded by the headlight. To us, it seemed that the headlights were aimed too low. I should be able to see more than 20 feet in front of my car. We were told that nothing could be done. Also, when making a turn, the area opposite the direction of the turn is completely dark because of the way the headlights work on a turn. This is extremely dangerous-should someone decide to walk there or if there is an animal, I will not be able to see anything. Again I was told there was nothing they could do. (3) my husband put rain-x on all the windows of the car. It worked on every window except the windshield. We thought there was some sort of coating placed by the manufacturer. I was told no there was not. They could not understand why the rain-x didn't take. They told me that they spent quite a bit of time "scraping the windshield", but nothing came off. We still do not know why it should do that. (4) I noticed. Whether I was driving in smart or sport mode, their is an annoying hesitation when I step on the gas. When the stoplight turns green, it takes several seconds before the car is able to move at normal speed. We were told that they received lots of complaints about that, but no offer for a fix.
Tl* the contact owns a 2018 hyundai sonata. The contact stated that the vehicle was taken to hyundai of kirkland dealer (11706 124th ave ne, kirkland, wa 98034, (425) 821-6611) where a software update was completed. The contact stated that when leaving the dealer while driving at 40 MPH, the vehicle stalled as the check engine and the engine control system failure detected warning lights illuminated. The contact stated that the vehicle speed automatically decreased to 10 MPH. The contact stated they slowly drove back to the dealer, where it was determined that a new engine was needed. However, a week later he was informed by the dealer that the wire harness had failed and needed to be replaced. The vehicle was repaired. The contact had spoken to the manufacturer via email and was provided a case number: 15658545. The approximate failure mileage was 3,713.
I was exiting the freeway and lost power, could not accelerate, blinking engine came on and on my screen it said "a possible condition with you engine control system has been detected. A full system check recommended to be done when convenient. Please contact you local dealership for an appointment" I was able to get to an area and have it towed. This could of been very scary and dangerous if I had still been on the freeway doing 70! I could not have driven it, it was missing and wouldn't get above 20-30 MPH. I had the knock sensor software update done at the dealer the week prior to this happening. The dealer is saying the wiring harness needs replaced and will not be available until the end of the month! Many on here have waited months I hope that is not the case. I've read numerous complaints on here and other sites that this is happening after the update. My car seemed fine before they did the update. Some people need new engines! How do I know that my engine doesn't have damage, I assume that hyundai knows something since with the sensor update they extended my 100k warranty to 120k. It said the sensor is to help catch possible rod bearing wear and extends warranty must mean they expect engines to have problems! What is going on here and why isn't there any official recall? My car only has 20k I don't expect this kind of problem. I leased cars for many years but since I'm close to retiring I bought this wish I was still leasing so I could get out from under this in 2 years!
My daughter was driving on the highway when the car started to buck and wouldn't accelerate. The check engine light came on and she pulled off the highway. She called hyundai and they told her not to drive the car and to have it towed to a dealership. We were then told by hyundai that this is a known problem. They installed a knock sensor wiring harness and said they hope that does the trick but it could need a whole new engine. Expected repair time is 6 weeks since parts are on backorder. We have since spoken to several dealerships as well as consumers and there are so many complaints that some people have been without their cars for months.
Tl* the contact owns a 2018 hyundai sonata. While driving 60 MPH, the vehicle became sluggish, decelerated, and failed to accelerate above 40 MPH. In addition, the check engine indicator illuminated. The vehicle was taken to napleton's valley hyundai (4333 ogden ave, aurora, il 60504, (630) 851-2500) where it was diagnosed that the wire harness needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and case number: 15704477 was provided. The failure mileage was 19,000. The VIN was not available.
While driving 30mph approaching a red light, my 2018 sonata cut off once I came to a complete stop at the red light. I was in city limits approaching a hwy intersection. The check engine light came on and the car restarted after one attempt. Once the vehicle re started it was sluggish,sputtering and would not accelerate over 20mph... I made it home safely nonetheless. I left the car parked for approx 10 mins and it restarted easily. I then drove it directly to the local dealer where the car was purchased. I was told the car stopped because the engine system required an update. The update was completed and I drove the car home. The next day or maybe two days later I received a letter from the dealership saying my car required a free recall and to schedule a date to have the car serviced. Over the phone I was told something along the lines of the engine harness needed to be replaced. When the car's engine cut off in traffic I was en route to picking up my toddler. I no longer felt safe driving the vehicle and I traded the car in and cut my losses, which were substantial. Other problems I noticed in the time I had the vehicle were that the back passenger seat belt locked or anchored if I leaned forward slightly and low visibility at night through the front winshield.
On 03/23/2019, when I was leaving a parking lot my car started to hesitate and would not rev up. I just turned out the parking lot when this happened. Message came on stated it need to be serviced. At the same time the engine light came on. I was not able to press the accelerator because it would jump like crazy. I was able to get back to the parking lot safely. I have been in a rental for a month now and as of 04/23/2019 I was told the part is on back order. The wiring harness and the computer has to be replaced, but the tech stated since the car went into limp mode the engine will need to be replaced. I was told the part will be in about 3 to 6 months. If the wiring harness does not work god only know how many more months it will take for a new engine to arrive. This car was only 9 months old but now 10 months old with one of the months being in the shop waiting for repairs.
I own this 2019 sonata since 1/16/19. Was runing good at the first. But couple times start showing the engine light for seconds. But on april sunday 14 2019 my car shows the engine light and the tire control stabilizer at the same time then the car start shaking lossing speed,the brakes getting hard and power steering. . Lucky I went at 10mph to 15mph.the vehicle will be placed in a temporary engine protection mode with reduced power and acceleration. No speed no acceleration then I park in a parking lot for towing at the nearest hyundai dealership. Technitia found code( p0638 ) active code and (p211935002a00 throttle body carbon cleaning- adjustment and found rubber grommet stuck in the throttle body roved grommet. This cause trouble with the intake and injectors making the car limp and state in protection mode. I have lucky I wasn't in the freeway at 55,60 to 65 MPH. O can be a different risk and dangerous for me and others drivers. Please take this note seriously before something worse can happen to others drivers . Thank you so much.

I have a 2018 hyundai sonata. I bought it on 12/26/2018. I now have 4,000 miles on it. Last month the dealership performed the computer software upgrade. Today I got a message: a possible condition with your engine control system has been detected with your 2018 sonata [xxx] on 03/30/2019 at 04:24 pm est. A full system check is recommended to be done when convenient. The car feels like it is going to die. Is this a common problem?

My 2018 sonata went to the dealer for the champaign 953 software update, for engine knock sensor enhancement . After the update was completed the car immediately went into to protection mode causing the car not to accelerate when pulling out of the dealer onto a 4 lane highway, nearly causing 4 people to injured. I have been told by the dealer and by hyundai that they have never heard of this happing before, but there are numerous complaints about this same instance happing to people on complaint sights. Hyundai needs to male it mandatory that these cars get test driven after the updates before turning the cars back over to the owners. It has now been 3 weeks since our sonata went in for the 953 update, we still have not received our car back, the dealer states they are waiting on a wiring harness to come in. So they are performing a software update to detect engine noise related to the knock sensor, because metal debris are coming off the internal motor parts causing failure and fires, that causes the car to go into protection mode. When a car immediately goes into protection mode after the 953 update is done, they say its a bad wiring harness picking up to much noise. Isnt that a sigh of engine wear that they want to cover up with replacing a harness that will not detect the noise. It does not take a engineer to see t.hat this is a major cover up
I was one of the first people to drive off with this 2018 sonata 2.0t trim in ending of 2017. Fast foward to now, I have been having electrical, lighting and engine problems. When driving at night, it is hard to see what's 30 feet from you on the ground because there's some parts that the light doesn't illuminate very well. When I have my car's interior lights on auto meaning to turn on, whenever I open the driver's door, it doesn't turn on. Sometimes my headlamps won't turn on neither, when I press the unlock button from my keys. Couple of months back and still is happening to this day my cars engine will start up funny or start up a couple of seconds late after pushing the start button. It even happens when I let my car sit for a day without driving. I've been to the dealer now and told them about the issue with the interior lights and I am waiting on them to get me some new lights for the interior (pretty sure that's not the problem). I know now that it's something electrical seeing all these comment/issues left on here. I paid too much to have this happening to my car. Maybe I should of just stuck with japanese smh. Help please.
Tl* the contact owns a 2018 hyundai sonata. While driving approximately 55 MPH, the vehicle shut off without warning. The vehicle restarted itself and would not exceed 20 MPH.

While driving my vehicle at nearly 70 MPH on the freeway, my car suddenly felt like I hit a brick wall and my check engine light came on and began flashing. I was then unable to accelarate past 55 and felt my car had a very sluggish response when stepping on the gas pedal. I was nearly hit by another car because there was no warning (break lights) when my car immediately slowed down. I then had to have my car towed 50 miles from where I was to the dealership near my home. When I brought in my car they said they had another car with the same exact issue. I called after my car had been there for approximately three days to get a status update and they said they still didn't know what was causing the issue, but that a third vehicle had now been brought in for the same issue. Today a week later, I called to get an update and the other two vehicles they are fixing with a new wiring harness; however mine they stilll are unsure what the issue is. This is now the third issue I've had with my car in less than 13,000 miles. Previously my car was having trouble starting the dealer said everything was fine. Also my front running light burned out at nearly 7k miles.
I went into purchasing dealer for first oil change at 5100 miles, they flashed computer and loaded update hyundai campaign 953 product improvement. About 50 miles after the recall was performed my car went into limp mode and is barely driveable. Car was also hesitating, and bucking a bit. Took it back to dealer they stated the code didn't apply to my car and flashed it again. It again went into limp mode after 50 miles or so. The recall is supposed to place the vehicle in limp mode due to rod bearing wear. My car has 5,400 miles on it and it now at a different dealer. Got information from that dealer regarding a tbs #19-01-002 and looks like engine replacement or wiring harness.
