2016 HYUNDAI SONATA Electrical System Problems

The contact owns a 2016 Hyundai Sonata. The contact stated that while driving and depressing the accelerator pedal, the vehicle failed to respond or exceed 30 MPH. The contact stated that the speedometer reading was lagging. The contact stated that the vehicle accelerated as intended while depressing the accelerator pedal with more force. The vehicle was taken to an independent mechanic, where the camshaft position sensor was replaced. Additionally, the contact stated that the starter was previously replaced due to the engine's failure to turn over while starting the vehicle. The contact stated that upon switching to Sport Mode and driving 40 MPH, the vehicle jerked and lost motive power. The contact shifted to neutral(N) and was able to pull to the side of the road. The vehicle was able to restart the vehicle, but the vehicle was undrivable. The vehicle was towed to an independent mechanic, where it was...

Engine started rough idling and knocking. Took to a mechanic who found metal particulate in the oil and the engine spun a bearing.

The driver’s seat / passenger seat assembly, including seat rails, mounting brackets, and Smart Junction Box (SJB) connections if electrical adjustment was involved, completely failed during a crash. The seat lifted off the floor anchors and almost entirely came apart, including both the seat cushion (where you sit) and the backrest, leaving the occupant crushed within the collapsed seat structure, resulting in catastrophic injuries. During the crash, the seat collapsed and disassembled, exposing the occupant to extreme trauma. This caused: •Pelvic fracture •Broken femur, hip, and back •Collapsed lung and punctured liver •Foreign object from the seat mechanism punctured pelvic bone The failure directly contributed to life-threatening injuries that would not have occurred if the seat had remained securely anchored. The malfunction posed an immediate risk of death and permanent disability. Not yet reproduced under controlled conditions. The incident has been documented by police and medical personnel. The vehicle is...

The shark fin antennae on top of the vehicle was ripped off in a car wash; the antennae serves to transmit radio/GPS/data to & from the vehicle which will cease to function if it the cover is removed and components damaged. Hyundai description: The shark fin antenna will receive AM, FM broadcast signals and transmit data Multiple Hyundai dealers have been contacted for quotes on replacing the antennae which they claim will cost $1500+ since the top of the roof must be removed and electronics/circuit board/cables must be replaced; it appears to be a common issue with these shark fins according to the dealers and online research. The GPS and data transfer could be a major safety factor depending on the systems affected. These shark fins need to be replaced with a more resilient system. Owners are unable to 'store' the antennae when taking it to the car wash as...

Oil pressure sensor failure caused oil to leak into the injector harness damaging components and engine shutdown. Because this was a sudden engine shutdown and safety-related loss of motive power caused by an oil pressure sensor failure this presents a safety risk

Vehicle stalled while driving

The vehicle experienced an engine and power train failure while driving on the highway, resulting in sudden loss of power. The electrical system also failed after the dealer visit, causing the battery to die every morning. Yes, the vehicle is available for inspection upon request. My car suddenly lost power on the highway and would not accelerate, forcing me to pull over on the shoulder with traffic moving around me. This created a serious risk of a rear-end collision or crash. Additionally, after the dealer visit, the electrical system began failing and the vehicle has been completely dead every morning, leaving me stranded with a child and unable to reliably start the car. The problem has not been reproduced because the check engine code cleared itself after the incident; however, the symptoms absolutely remain. The dealer refused to diagnose the loss-of-power event because the code was cleared, and they returned...

Pushed acceleration at traffic light to cross and turn into neighborhood, car started beeping frantically, 'check hev system' flashed on dash as well as 'turn off engine' while car decelerated to 1-3 mph.

Tengo este sonata ya 3 años a solo un mes de haberlo comprado empezó con los problemas de check hybrid system todo el tiempo el mecánico no sabe que pasa con eso además siempre cuando se enciende esa luz no se puede manejar el carro y le dice que tengo que apagarlo

While driving, the vehicle's engine light will randomly turn on and when it does, the car will lose power; meaning, when this occurs, and I press the accelerator pedal, it does not put out the normal, expected amount of acceleration. This problem will persist until I pull over, turn off the vehicle, and turn it back on. However, this does not always fix the issue. Sometimes, when I turn the car off and turn it back on, the check engine light will still be on and I will still encounter the issue. When I brought my vehicle into my local Hyundai dealership, they had the car for 3 days, and when I called to ask what was wrong with it or what they did to fix it, they told me they could not recreate the problem and therefore, did not do anything to the vehicle. So now, I'm at an...

My car burns through approximately 1qt of oil every 500 miles or less. There is a known oil consumption issue and I have left multiple messages with Key Hyundai of Milford CT and do not receive a call back. Additionally today I was driving 25mph and my car was reading 4000rpm and then completely locked and shut down I was stuck in the middle of the road.

Car is still driving good, but after I've had it for a little over a year now the first thing I noticed was my horn went out, then the headlights went out, then my temp gage is flashing and the engine light comes on & off. Certain dash lights come on & off. I just got an oil change. I've been taking my vehicles to Pep Boys for several years now. My last oil change on the Sanoto was the 3rd or 4th oil change . One of the reps told me that my car is now consuming oil. He said it's not leaking on the ground but something is causing the oil to burn. I don't know if you have a warranty on it but he suggested I take it to the dealership. Again I've only had it a little over a year. I'm financing the vehicle and have...

Vehicle suddenly shuts down while driving. This has happened several times and has cost lengthy repairs and towing fees but still keeps doing the same thing. After it shuts down once the car is reset it will work again for a little while and do the same thing over again.

While driving (speed doesn’t matter, highway or city streets) the check hybrid system turn off engine message/code comes on. When u turn off the car and wait for a period of time the it’s not there anymore but the check engine light stays on and the car drive normal until the code comes back up. When the message comes up the engine loses power and and the car just slows down until the car is turned off. This is a safety hazard when you’re driving on a freeway and especially a freeway with no shoulder to pull over on or going through a read light with no speed. The car just does it periodically and when u take it to the dealership they say they can’t duplicate the problem. When all u do is hook a computer up and look for a code when the problem arises while driving you’re...

I am having electrical issues with my 2016 Hyundai Sonata plus the other recalls. It started as issues with the lights on the driver side. I have replaced several bulbs and the entire light even and still have issues with the lights working properly. Now the issue is the battery, alternator or the starter. The starter had to be replaced as I was advised by Hyundai dealership when my engine had to be replaced, per recall. I had to purchase a starter, that was three times the amount at the dealership because the one that is manufactured in the auto stores is not correct, so it should not be the starter as it is only 1 to 2 years old. I have had the alternator replaced as well as 2 batteries and I’m still having issues. It cut off completely while driving on more than 1 occasion. There was no...

My husband (Scott) was driving the car on Florida highway 408 eastbound approaching the exit 21 on 10/12/2023 around 8 am. Scott heard something pop suddenly and saw fire shooting out from both sides of the car in the rearview mirrors. Upon noticing the fire, he tried to slow down to pull over the car, but brakes failed (went to the floor). A police officer on the road happened to see the fire so he drove next to my husband's car and Scott yelled at officer that he had no brakes. The officer went ahead of Scott to help Scott's car slow down. When approaching uphill slopes by the exit, Scott was finally able to use the emergency brakes to come to a complete stop. The fire engine came right away and put out the fire which took over 20 minutes. My husband is handicapped and him walking away from...

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...

Knock Sensor, ECM, Engine stalling and loss of connection. Resulting in flashing engine light. Low acceleration. Power reduced to 40 and below Engine misfire.

Car was leaking oil I reported to Hyundai and service repair shop had to take it back 3 times due to them neglecting to listen to me oil got into other parts and I had to get 7 things fix also after having back for 1 day the brakes and electric is not working properly engine also fails to accelerate correctly

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...

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.

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...

Electronic Power Steering (EPS) Failure.

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...

Had previous issue with HEV warning light and took to dealer. But While driving down the road last night, the HEV light on the dash comes on and beeps, the car sputters then the brakes slam on and the car immediately shut off in the travel lane. Turn car back on put into drive and same thing happens. Vehicle was towed to Dealer.

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.

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.

Ive bought this car used at 30k miles currently at 79k in 2020. Ever since this car has been given me nothing but issues. On 6-24-22 for the third time in two years the car would lose all power going 60-70 mph no gas, no battery engine wouldnt work all while driving on busy I-95. I refuse to drive this car any longer as it is not safe for myself and other drivers around me.

Car unexpectedly stopped working and became disabled while trveling 40 - 50 mph on the freeway. Complete loss of power. Danger of a collision on the freeway. All dash lights and warning lights came on. Car would not shift and would not accelerate. It was unsafe to drive and could hardly move off the road.
