2014 HYUNDAI SONATA Complaints

Lost power to vehicle while driving on the freeway, hybrid system warning was displayed as well as several lights to include engine, brake, and skid control. Had the dealer replace the knock sensor, 3 months later the exact same thing happened, in the same way. All the same obd2 codes were pulled both times.

On the dashboard showing " Hybrid system warning. Safely park and do not drive" sign while the vehicle is being driven and slowly loose its power till completely stall. After I turn off the engine and try to turn on again ,the "Ready" sign keeps blinking. I was twice stall by the exit of a freeway. It's very dangerous. I also found a few recalls related to this issue in the past.

Im not aware what is malfunctioning or failing but I get a warning to not drive the vehicle and I start hearing a beeping sound, when I try to break it makes a harsh screeching sound and tugs the car a bit. It’s putting my safety at risk bc I drive for work and I can’t keep having this problem happen on the freeway. I’m afraid my brakes will fail and not break. Idk what the cause to this is, I’ve had two different mechanics take a look at this and no codes pop up. No warnings pop up either. This has been going on for almost 3 months. I can’t drive this vehicle with this problem and it’s the only one I rely on for work and my everyday needs. If you guys can please help me out or look into it I will be waiting for a response. Thank you

When head lights are in Auto mode occasionally all of the exterior and interior lights go out. Including dash lights. I cannot make it repeat at will so nothing ever gets done with it. There is no warning when it happens just complete darkness inside and out. Obviously I can’t see where I’m going when it happens they typically come back on after a few seconds. This has been happening for over 1 year. I don’t use the lights in auto anymore, it doesn’t happen when it’s not in auto.

My tail lights, brake lights and head lights continue to go out. I have replaced them many times myself and have taken it to the Hyundai dealership. They temporarily fixed them but couldn’t promise how long they would work. They said to fix them would cost over 1000$. This is a safety hazard as not having brake lights could cause serious accidents. This doesn’t seem Normal as I have never In my entire time I have been driving had to continually replace lights. Sounds like a manufacturer defect and I feel like the dealership should have to pay, not out of my pocket. I have been pulled over by the police and have had to explain why my lights don’t work. It’s scary because I never know if they are working or not. I did not get any warnings on my dashboard that lights were out. I have also googled this problem and it seems like a lot of the same year of Hyundai vehicles are having the same issues.

While driving normally on the highway I received the "Hybrid Safety Warning: Do Not Drive!" error. The engine began sputtering uncontrollably, the brakes weren't fully responsive and I lost power steering. Thankfully I was able to coast down the road and pull over. If this had happened in traffic I can't imagine an accident would not have happened. Not being able to brake safely or steering properly while your engine is sputtering out of control is terrifying and a MAJOR mistake in design and implementation.

While driving the vehicle the lights on the dash start to flash, stating that there is a Charging system warning. It says to pull over and not to drive. It becomes very difficult to brake, or steer, almost like the vehicle has lost power. It blew warm air and the check engine light also came on. This can be extremely dangerous if one was on the highway or at an intersection or any place where they needed to pull over to safety. My 12v battery was checked and found to be fine. I called multiple mechanics to come take a look at the vehicle and the codes that were read were P1B77, P1B96, P1B70, P0A0D. The 150 Amp fuse was said to be blown, and was replaced. Sometimes the car will start back up, and sometimes it won't. Currently, it's sitting in my yard. The engine and interior look pristine, but there is something going on with these vehicles that isn't being addressed. This car is dangerous and there are many, many, MANY people that I'm finding on Reddit, YouTube, and the Hyundai forums who are having the exact same issues. I unfortunately cannot afford to continue to keep hiring mechanics, nor to have it towed to the dealership, only for them to do what they are doing with countless other people. They do not seem to understand the issue either and are grasping at straws to replace expensive parts, only to have the issue reoccur. Something needs to be done about this before someone is killed.
