2016 Hyundai Sonata Electrical Problems

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.

On February 6, around 3:46am, parked my vehicle on the driveway I noticed a smell like smoke, I looked at my dashboard but nothing was on, no warnings, so I entered my house a few minutes later Possibly 4 I heard a noise look outside from my window an noticed my car was on fire, immediately called 911 car garage door also cut on fire and the vehicle next to it.

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 such car catastrophic fire unharmed was near miracle. Two weeks before the fire, I happened to take the car in for checkup at Greenway Hyundai Orlando and the 2.5 hour inspection found nothing wrong with my car. I wanted my car checked because my car stalled briefly pulling out of a parking space a few days earlier.

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.

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.

Engine caught on fire while driving

I recently totalled my car due to "following to closely" which I didn't have GAP insurance. Truth is I signaled to go right lane when The car in front thought inwas going left due to faulty recall problem and we both went right, I lost control and hit a rail and damaged car unfortunately

When I was at work the engine gave up with no warning and could have gotten very dangerous for me. when I called the dealership they said because my car was totaled, but when I called NHTSA they told me that they didn’t have the remedies. I just thought that was strange.

Fuel Pump Control Module replaced before 50,000 mi. - 58,539 mi. got my 2016 Hyundai Sonata Sport for ECM Update.

Yes I was driving on the expressway I saw smoke coming from my vents. I made it to the nearest neighborhood by my home stopped for it to cool down for 10 minutes I start my car back up & it was perfectly fine by time I made it to a stop sign it caught on fire while I was in the car. The fire department told me it was due to an electric/engine problem & nothing was my fault.

Reciban cordiales saludos, el 11/01/2020 dicho vehiculo es usado como lyft venia de pasajero y tuvimos un accidente. Las bolsa de aire jamas se abrieron, echo que agrabo mi condicin. Ya que impacte mi cabeza fuertemente contra el marco de puerta del vehiculo ocasionando mi lesion cerebral.

During long distance driving once the vehicle is stopped for gas the hev warning light comes on. The car will not re-start for 15 -30 minutes. Once restarted the check engine light comes on.

My right high beam stopped working, I have to add oil to my car every 3 days. Burns more gas going back and forth to work. Going around a fast highway curb, the engine shut down the speed of my car and would not stop dropping down to 45 MPH in a 70mph packed highway.

When driving sometimes the bsd system turn off without any advance warning, this could cause accidents, the blind spot collision warning hyundai need to be reviewed well and address the issue. Many people complain about this.

Hard shifts when in sport mode and when it doesn't do a hard shift the vehicle will shut off on the highway causing the headlights and power steering to not fiction cause a possible crash have to stop and put in park to restart engine

If I open the driver side door while the vehicle is on, a warning light "check bsd system" is displayed on the info display. The warning stays on until the vehicle is turned off and turned back on. It shuts down the driver assistance feature on the vehicle.

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. Battery meter bar on left side of dash completely depleted showing no battery power supply at all. Turned vehicle off for a few minutes then restarted.

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.

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.

Tl* the contact owns a 2016 hyundai sonata. While driving approximately 40 MPH, the contact heard a ticking noise coming from under the hood of the vehicle. Also, the oil light and check engine warning indicators illuminated.

Car was in motion at about 75mph on the highway when it jerked really hard then lost all power, making it a very unsafe situation for not only my family but also other drivers. The lights on the dashboard went all crazy and it hasn't started since that happened, car was towed to a dealership where they are stating it's a recall on the ecm.

Tl* the contact owns a 2016 hyundai sonata. While driving approximately 25 MPH, the vehicle shut off without warning. The vehicle was towed to the dealer (legacy hyundai in mcdonough, ga, 770-914-2800), but the failure was not duplicated.

We were driving along at 70 MPH and suddenly the engine stalled and electrical gauges all turned off for 15 seconds, meaning all gauges went to the left like when you turn your car off. Dealer said that they found nothing wrong. They said to let them know if it happens again?????????????

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.

The contact owns a 2016 Hyundai Sonata. The contact received notification of NHTSA Campaign Number: 21V749000 ( EXTERIOR LIGHTING, ELECTRICAL SYSTEM); however, the part to do the recall repair was not yet available. The local dealer was contacted.

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.

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.

For a year the radio would not work or play at times or you heard audio but absolutely no visual screen as far as the channel your on etc. Also, the same screen for backup camera the dealer told me on phone, on the face of radio there is a tiny pin hole use a pen depress it and it will reboot the system I did and it worked.

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.

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.

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.

I got the oil changed on my 2016 sonata. The mechanic that changed my oil told me the engine was low on oil when he changed the oil. A week later I checked the oil to make sure the oil level was good still.

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.

The hood open sensor is displaying that the hood is open when it's been closed and is latched.

2016 hyundai sonata. Consumer writes in regard to lack of security transponder.

Car was stolen on 12/27/22 because 2016 Hyundai Sonata does not have an engine immobilizer - highly likely inspired by recent Hyundai/Kia TikTok challenge.

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.

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.

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.

The Car is flash on Dash boards Check HEV and turn off the engine cause my car to idle. Turn off my car for 20 mins signal gone Then 2 weeks later randomly does it again. Car also flash Check Breaks on dash boards and turn off the engine and it shut my whole car off

Radio doesn’t shut off when the car is turned off. Radio will freeze and won’t work ( won’t turn on or volume and other dials doesn’t work ).

When headlights switch is in the auto position and you use the right turn signal the headlights go off then come back on. I've had this car for 4 years and noticed this a lot. Left signal is starting to do the same.

Paint coming off the top of the car and I have to change my front light and brake light every month it goes out

Blinker doesn't work. Engine has a hole in it.

The car when driven highway miles will not crank when you stop the engine. The check hybrid system light message comes up. The car will not start for 15 to 45 minutes.

Rear tail lights keeps burning out. This seems to be consistent with other consumers and hyundai has not done a recall. See forums and videos online from other complaints.

Takata recall when driving my vehicle and attempting to lane change or attempting to make a left turn and I pull my indicator down to indicate that I'm going left instead of showing left it indicates right turn and

I was driving the car and the car started spitting and did not want to go. Then white smoke came out of the tail pipe. I cut the car of and waited in traffic with my baby in the car , then turned the car back on.

Passenger power window will not lock out. Only the back window lock. My dog hit the window button and the window opened and the dog almost jumped out on the highway.

TPMS indicators continue to say there is an issue and the tire and tire pressure but the car shows the correct tire pressure and there is no damage to the tires.
