01/26/22 Brought 2016 Hyundai Sonata to Fremont Hyundai (Fremont CA) for "Smart Junction Box" recall. 08/12/22 Brought vehicle to Fremont Hyundai for intermittent turn signal recall. 04/10/23 Brought vehicle to Stevens Creek Hyundai for "A 993 HYIMMOA0 -Sonata (LF) S/W UPD & DECAL (23-01-014H-3) RECALL DEFAULT 31599 WH." Told the service dept the vehicle was still having turn signal issues. Refused to correct instead told us to need to bring back to Fremont Hynudai otherwise wanted to charge us $250 to correct it. We felt Steven Creek Hyundai should have corrected this instead of sending us back to Fremont CA.

The problem appeared on December 2020 in the middle of a Hwy 50 East in Washington DC. It was scary and dangerous. First it showed some malfunction sign on the screen and right way slowed down to 40 then 20 then zero. I push the gas pedal but didn't work. I have no idea what to do. I call Hyundai college park dealership agent explained what happened. She [XXX] told me to tow the car and suggested one of their partners tow truck driver. However when I turn off the car and turned on again it worked. The engine started to run. I begun to drive. After some time I took the car to the dealer and told me the car have safety recall. The repaired it and told me it will be ok. But in reality, it didn't. This happened again and again and again. Till this moment the engine continues to stalled in the middle of HWY. I got no solution from the dealership. When ever I visited they give me different issues that I need to fix. One time they said it is fuel pump and another day they said coolant pipe needs to get fixed. I am so tired of keep going to the dealer services. I put my life and my precious kids life at risk all the time while I am driving this car. It is frustration because I got no one to help me and understand why this issue is persistent. I don't want to end up being injured or got killed by an incident that caused by this problem. How awful it can be if a collision happens in the HWY. Driving this car every day with my kids are frightening and hard to imagine what could happen to us. So I am requesting an investigation on this car with the case number I got from the headquarters. Here is my case number [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The airbag light is on, indicating that the airbox is not operating and will not go off in case of an accident. All steering wheel controls also don't work so it's impossible to adjust settings using the steering wheel or to enter cruise control at all. Previous years of this same vehicle had clock spring recalls and this appears to be the same problem so I wonder if the other recalls should be extended to this year vehicle? thanks

I-??ve had this vehicle for exactly 6 months. First incident where I thought the company I bought it from lied to me because they said they topped off my oil. In reality it guzzles oil excessively, I paid $600 to get it cleaned out & add oil. 2nd incident my car shut off at a McDonald-??s drive through, no indication of warning of shutting off until 30 seconds before all error codes on dash. 3rd incident as of 02/07/23 car completely out of oil when I had an oil change a month & a half ago. Had someone come & bring me oil & it seemed to get me a mile away to school, did my school stuff & then tried to get home (30 miles away). When trying to get home my car wouldn-??t exceed 60mph and when I got to 62mph it was decreasing speed. After a few moments after noticing that, all error codes on dash came on and I thankfully was able to pull over on the freeway without being hit by anyone. My car completely shut down, called a tow truck, while I waited 3 hours for assistance. I was then notified(by the first shop I took it to) the next day that my motor is BAD & I-??m lucky that I was able to pull off to the side of the road when I did. A week prior to the 3rd incident random chunks of painting ripped off my vehicle(on the top of my trunk, above the passenger door & on the back side of the passenger door). I had my vehicle towed a second time to the Hyundai dealership themselves and the towing company asked the color of vehicle/make and model and instantly said oh is it your motor" I was weirded out because I was wondering how he knew. He mentioned to me that he has towed 25 Hyundais in the last 9 months. I said well you-??re on a role, you can now make it 26. I was also never notified of any recalls on this vehicle until 2 days after the 3rd incident I did my own research and called Hyundai dealership myself & that-??s when I was made aware of a recall. Insurance also states that this isn-??t something I can claim" & I-??m currently waiting to hear back from the dealership themselves.

My car idles very rough at times, and sometimes when idling, it dies out. At times it is difficult to even start as if it's not getting the electrical signal to the engine. Hyundai replaced the fuel pump, but that did not fix the problem, but cost $1,200. No warning messages. Two other automotive companies also did a diagnostic tests, but couldn't find the problem as it seems it has to be tested WHEN IT IS ACTING UP. It died on me far from home a week ago, but eventually restarted. I'm afraid to drive it especially at night as it died when idling at a light and almost didn't restart.

While driving the hybrid system warning light comes on and says to check hybrid system, vehicle goes into limp mode will not accelerate over 25 mph and codes need to be cleared before vehicle van be driven. This has caused me to almost have several accidents. The vehicle slows down and gives no warning prior to this occurring. It has started happening more frequently vehicle currently has 85k miles.

The vehicle is able to be started without a key by using a usb cable. This makes the vehicle extremely vulnerable to theft. Because of this issue vehicles incur other damages due to theft such as broken windows and possibly bodily injury due to theft. They are able to remove the steering column cover, unplug the ignition switch and using a usb cable as an object to turn the ignition. Because the switch appears to be plug and play it makes it easy to steal cause Hyundai car owners unnecessary dollars for repairs. https://youtu.be/fbTrLyqL_nw This is the link showing what they do. It-??s not just Kia vehicles. My vehicle was stolen the same way.

My vehicle is a hybrid and the Check Hybrid System light has lit up while I'm driving and you have to pull over and turn off your car when that happens. The car will slow down and come to a complete stop regardless. It's scary when you are driving on the freeway. I've had this happen to me several times and my car has been worked on four times now by the Hyundai service department in Amarillo and Lubbock TX. I purchased extended warranty and it's about to expire at 100,000 miles. I currently have around 82,000 miles on my car. I contacted the Hyundai corporate office and have a case number. I'm very disappointed the way the Hyundai corporate office and the service department has handled my situation. I even lost my job because I had no transportation for two months. I just paid off my car yesterday and I can't even drive my car.

While driving on the highway at speed, I received a red Check Hybrid System error, and immediately lost all acceleration, putting myself and all occupants at risk on a busy interstate highway, as we tried to find a safe way to quickly change lanes and coast to a stop in a safe location. The cause is under diagnosis by a Hyundai Service Center. This was a sudden failure and there had been no previous warning alerting us to substandard system condition.

My vehicle lost power exiting the freeway. I went from 70 miles an hour to 10 miles per hour in a matter of seconds. The Check Hybrid system, Turn off engine HEV ! triangle showed up on the dash, then the car slowed to a halt. I had to get my vehicle towed home, then towed to the dealer the next day. The problem with this is, for the past year, the Check Hybrid System HEV light would come on. I took it to the World Car Hyundai North dealership in Live Oak, Texas and a few months later, it's doing the same thing. My vehicle was in the shop at World Car Hyundai from March 24, 2022 until 9/9/2022. I drove my vehicle one week, went out of the country for 2 weeks and upon return, coming from the airport almost home, the car does the same thing. You would think after having my vehicle for 6 months, the problem would be fixed. I started bringing my car in for this problem September of 2021. I was told, I needed an oil change, a new battery, ne plugs, codes checked, etc. None of this seemed to fix my vehicle, because a few weeks later, the car would slow to an almost stop and I would have it towed to the dealership again. There has been several mechanics working on my vehicle and they've all said something differently. My vehicle was never written up for the correct problem until recently, when the manager was able to drive my vehicle and it stopped on him. I don't feel safe driving this vehicle anymore. I have taken this car to the dealer ship for the same problem, actually once in 2018 and every other month since 2021. I've been inconvenienced, , put on hold, far to long, I need a new vehicle and I need a loaner car, while my they're trying to figure out what to do. I've been told I needed a new engine twice, but all of a sudden, it passes the engine test and there is something else that the dealership is trying to do to fix the problem. Well, since I've been taking my car back and forth to the dealership, it is now out of warranty. The car remains unsafe to drive.

Somehow, either by design or manufacturing defect, a part in the headlamp assembly melts and causes a gap in the illumination of the lights while driving. Technicians have said that this is a progressive issue, rather than some sudden onset, and multiple people have said they've never experienced this before but are having this issue with the Hyundai Sonata.

My 2016 plug in hybrid Sonata repeatedly inidcates that there is "high system temperature switching to hybrid mode." This first happened on my first long trip in the car in 10/21 and has happened repeatedly since. This happens at all temperatures, including moderate temperatures (mid 70s). It seems to happen randomly, such as when battery has several miles of charge left in it, when it is fully discharged, and repeatedly when the car is already running in hybrid mode, which a driver could interpret means that the engine is about to shut down, as I did on a long trip. I have taken it to two separate dealers, and the only thing they did was replace the fuel pump, which did not solve the problem. In addition, the battery life has reduced greatly, despite the fact that I always fully discharge and recharge the batter. As you can see from the attached Hyundai forum comments, this appears to be a prevalent problem for this make and model car and no relief from the manufacturer appears to be on the horizon.

The vehicle is highly susceptible to theft. There are multiple articles and videos on how my vehicle and many others made Hyundai and Kia can be stolen in minutes with just a USB drive. This needs to be investigated and fixed immediately.

The car requires a quart of oil every 1 to two weeks. Brought it to multiple dealerships and was never given a reason why. Car was making knocking noises anytime driven at 45 or below and sometimes higher. We believe it had to be about the recall Hyundai has advised us about multiple times. We brought it to them on Friday July 22nd. They updated the Hybrid system and we left. Driving the car to work July 27th and the car went into -??limp-?? mode and stated that there was a issue with the hybrid engine and to shut the car off immediately. I was able to pull the car off the road and turn it off. The engine light constantly blinked when the error happened. When I shut the car off and turned it back on, it the same hybrid error shows up on the screen again. We had to have it towed to the same dealership we went to the previous day. They have to diagnose the issue but it might take weeks because they have one hybrid tech.
