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 it is not removable or retractable. It is a design flaw. I've read that many have lost them simply driving the vehicle --not agitated using a car wash.

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

- Sterling , VA, USA

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 the vehicle to me with a dead battery. The electrical issue (car dying every morning) has been happening consistently since the dealer visit. The vehicle was taken to a Hyundai dealership immediately after the incident, but they refused to diagnose the loss of power due to the code being cleared. A mobile mechanic scanned the code at my home before the tow, but the code disappeared afterward. The electrical failure began after the dealer visit and has not been properly inspected by Hyundai. Yes. While driving on the highway, the check engine light came on and the car immediately lost power and would not accelerate. After the dealer visit, the car has been completely dead every morning and requires a jump to start. These symptoms began on the same day as the highway incident and continued after Hyundai serviced the vehicle.

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

- Clinton, CT, USA

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 impasse where this problem is not able to be recreated, thus, unable to get it fixed, but I don't feel completely safe to drive long distances. I also own a 2013 Hyundai Sonata that experienced the same type of issue, and that engine was recalled.

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.

- Seymour, CT, USA

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 about 4 more years to go. HELP!

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 never going to find the issue. No the dealer hasn-??t reproduced the problem because they didn-??t drive the car just leaving it to sit up and checking codes doesn-??t bring the problem to light. They wasn-??t any warning signal or codes before this but not code p2600 and code p0401 are coming up. Spending $2000 for a part that will can-??t be ordered anywhere but from the dealership and the problem still exist is not being logical. So many online reviews have the same problem and not one person has found out the problem from changing the electric water pump to transmission to the engine the warning sign still come back after some time. Me not being the 1st owner and the car out of warranty due to mileage is just robbing folks blinds with no solution.

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. However, as time went on it started to happen more frequently now the radio or screen completely do not work including back up camera. Finally, today officially had fuse checked which is good. There is absolutely no back up camera period or radio or screen display of any kind. I have done research it seems to be common on this vehicle but now a major safety issue and not covered under warranty and extremely expensive for a car with only 50 thousand miles ridiculous

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 warning, no power steering, gear lock, no lights & no power so I could not move and almost had a major accident. It is definitely a safety hazard even after the repairs, it has happened again! My vehicle is currently not working because the new battery will not hold a charge and they both have been replaced. I-??ve been having other electronic type issues with this vehicle. My information center has not worked for the past 8 months or so! I reported this to Hyundai and they agreed that it could be a part of a previous recall, and advised me to go to the dealership to have it repaired. The dealership refuses because they don-??t have required information to show it as a Current recall and want to charge me half the price of a new car to repair. I am not the only one experience this as my research has led me to several other Hyundai owners experiencing the same issues. It is not fair that they cannot be corrected as these are things that are none of consumer fault & should have been high demands to proper repair or recall being a major safety issue as it can cause a horrific accident! Shame on Hyundai for putting their Hyundai customers at risk & through so much chaos!

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.
