2015 HYUNDAI SONATA Complaints

The contact owns a 2015 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, the check engine warning light illuminated, and the vehicle lost motive power. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure; however, the engine replacement request was denied. The failure mileage was approximately 140,829.

My transmission literally went out once on me the SECOND DAY after I financed it. Now, less than a year later, it says I need to replace the transmission again. This is ridiculous.

The air bag sensor located in the front passenger seat does not function. It is available for inspection upon request. Because the sensor doesn't engage, the passenger-side air bag will not deploy in the event of an accident, leaving my passenger at risk of serious injury or death. The Hyundai of Cool Springs dealership in Franklin, TN, has inspected the car and confirmed that the sensor is not functioning. The sensor, if properly working, will show a glowing red light on the dashboard that goes on when a passenger sits in the passenger seat, and goes off after a few seconds. In the case of my car, however, the dashboard light goes on when a passenger sits and stays on (glowing red) the entire time the passenger is seated. This defective dashboard light, according to the Hyundai service technician, indicates that the sensor needs to be replaced. The cost the technician quoted is prohibitive at $3,500.

The wrong turn signal lights up. I know there is a recall for this but my vehicle does not come up when I search for affected vehicles.

My vehicle has an oil consumption problem despite the fact that my car has been excluded from the class action lawsuit. I’ve had it in the shop and they have confirmed the oil consumption issues. There are countless other vehicles excluded from the class action lawsuit that have the same theta engine as the other vehicles that were included in the lawsuit. This needs to be investigated. I still owe over 6k on my car and it’s one trip away from being completely undriveable

I have been driving at night about 3 times now and my headlights have gone off on their own and come back on after about 10 seconds. This has happened on countless other Hyundai drivers vehicles and needs to be investigated.

The contact owns a 2015 Hyundai Sonata. The contact stated that the check engine warning light illuminated after having the oil changed. The vehicle was taken to a certified mechanic and the contact was informed there was no oil in the engine. The contact had paid for a better grade of oil in the vehicle. The mechanic inspected the engine and could not find any failure. After having the oil changed the check engine warning light was illuminated. The contact had taken the vehicle to another mechanic approximately 3 weeks later who was unable to find any failure with the engine. The mechanic had reset the sensor. While driving approximately 5 MPH, the check engine light illuminated. The vehicle was returned to the mechanic who reset the sensor again. After having the vehicle serviced, while driving approximately 50 MPH, the warning light illuminated again, and the vehicle stalled. The vehicle was towed to the mechanic and the contact was informed that the O2 sensor had failed causing the engine to seize. The vehicle had not been repaired. The dealer had been contacted, and the contact was informed that the vehicle had a Salvaged Title and there would be no assistance provided. The manufacturer was not made aware of the failure.

The contact's husband owns a 2015 Hyundai Sonata. The contact stated while the vehicle was at an independent mechanic for an oil change, the contact was informed that the vehicle was experiencing excessive oil consumption and that it was a known failure. Additionally, the contact stated while driving 73-74 MPH, the vehicle shuddered and stalled. The contact was able to pull to the side of the road. The vehicle failed to restart and was towed to an independent mechanic, where it was diagnosed that the rod bearing had caused engine failure. The dealer determined that the engine needed to be replaced. The mechanic informed the contact the failure was due to a factory defect and would reoccur even after the engine replacement. The vehicle was taken to the dealer, where the same assessment was made. The dealer filed a claim with the manufacturer and sent a diagnostic report with pictures of the failure; however, the manufacturer denied the claim several times. The contact stated that the engine was previously replaced. The manufacturer was notified of the failure. The failure mileage was approximately 152,550.

Was driving on the access road... Luckily .... When I lost all power. Turned off my car and wouldn't restart. Had it towed , 1 month later and $7500 had to get a rebuilt engine. Which now I'm having 100s of issues. Love my car but this is literally stressing me out. Bought the car 2 months before this all happened

I purchased a 2015 Hyundai Sonata. Two years ago, I'm having issues with my car paint peeling off in the hood, roof and trunk. Many times I when to the dealer to ask them about the recall, and they state that there is nothing they can do since they did not have anything registered for a paint peeling recall. My car day by day is getting worse and I need help for this issue to be fix.
