Car will not start when key turned in ignition with no sound when the weather is under 30 degrees. Had it in the dealer last week and they could not find the problem. Still happening so its back in the dealer for 3 consecutive days and I cannot talk with anyone in the service department. Phone just rings then cuts off. Have done research and found other 2018 Sonata ES owners with the same problem and the solution has been the ignition starter and solenoid. When replaced the starting problem was solved. Three days now and have not heard form the Hyundai repair shop in bowie, md. Still have my car. Such inefficiently with mechanics now days.

I was driving my car at about 45mph on my way to work on a highway road and out of no where it jerked and the check engine light started flashing. Car would not accelerate above 2,000 rpms. When the car jerked, it was so sudden it injured my lower back. My back has been very sore since this incident. I then took to dealer and they said it was a known issue and Hyundai had not recalled my specific car. Dealer was able to replicate the issue. The cleared the check engine light and sent me on my way. One mile down the road exact same thing happened. Car is currently at their shop with no eta of repair.

My 2018 Sonata will not start when temp drops below 20 deg F. it has happened 3 times this winter and when it warms back up to 40 to 50 degree it will start. When I turn the key on all the lights on the dash light up like normal. I can move hear selector and turn wheel. But the starter will not engage nothing is heard not a click or a shirt. Is this common problem?
Entertainment screen turns off after a while and will reset or I have to tap it and make sure it goes back on and does this over and over at times. Smoke comes out exhaust when passing a car sometimes
The contact owns a 2018 Hyundai Sonata. While driving, the visual alarm system and automatic braking system did not work. The vehicle was taken to two different dealers, including lake norman Hyundai (704-274-3145, located at 20520 chartwell center dr, cornelius, nc 28031) where the technician stated that road tests were not allowed on such vehicles. One of the dealers provided the contact with tsb: Group brake 18-br-001. The manufacturer was made aware of the failure and stated that nothing could be done. The vehicle was not repaired. The failure mileage was approximately 4,700. The VIN was invalid.
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.
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.
Check engine light came on;engine error code 1326. Car began stalling. Got it to dealer who knew it would need a new wiring harness possibly a new engine. This is dangerous will get someone killed. This happened right after exiting the highway pulling onto the service road.

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!

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 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.
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 took my 2018 Hyundai sonta SE in for its first oil change with 3564 miles on it. They did a computer update as part of a recall. I drove less than ( miles from the dealership, went to pull out from a stop light. It started miss firing and the check engine light started flashing. I went back to the dealer. They said it had a code and tgey had to call Hyundai to find out what to do. They gave me a loner and told me the wiring harness had too much interference/static in it and they had to order a new one. Very hard to believe a computer update would cause the wiring harness to go bad.
