2015 HYUNDAI SONATA Complaints

While driving in city traffic, 45 mph zone, my car suddenly lost power, engine RPMs dropped, engine off, power steering impaired, I had to drift into turnout and assess. Car restarted, and I could drive, but RPMs would not exceed 1700, car wouldn't shift gears, speed would not exceed about 15 mph. No engine warning lights, no oil pressure indicator, no excess heat. I found I could drive at low rpms and manually shift gears to increase speed. I got the car to the local Hyundai dealer (Taylor hyundai, Augusta GA) and it has been there 8 weeks. They are telling me the engine has failed because I failed to change the oil for 14 months. They said my oil pan was empty. They asked me for maintenance records and said they were inadequate, and the engine needs to be replaced, may cost $6000 or more, warranty invalid. The car has 56,000 miles. Safety was put at risk due to sudden loss of power in busy traffic. Driving the disabled vehicle was risky to surrounding traffic, as the car could not maneuver quickly. I have read about similar failures with Hyundai Sonata vehicles, and a class action suit settled for 2011 to 2014 model vehicles. My car is still in the shop, unrepaired. I had to buy another used car in the meantime.

The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at various speeds, the steering wheel would suddenly become extremely difficult to turn in either direction. During the failure, the steering fault warning light was illuminated. After turning off and restarting the vehicle, the vehicle operated as intended. The vehicle was taken to the local dealer who was unable to duplicate the failure; no service was performed. The manufacturer was notified of the failure but no assistance was offered. The VIN was not available. The failure mileage was 80,000.

We have had some issues but take very good care of the car maintenance wise. The car went into limp mode and we took it in they ran it and came up as the knock sensor.. I noticed there was a huge recall for these cars. What can I do? It has 140000 miles and again we keep up on the car. Is this something I need to seek counsel for? Thank you for your time. I look forward to hearing from you, Dominique

The contact owned a 2015 Hyundai Sonata. The contact stated that while driving at approximately 60 mph, the vehicle decelerated independently while the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the sparks plug and the PCV valve needed to be replaced. The vehicle was repaired however, the vehicle check engine light recurred. The vehicle was taken to the dealer where it was diagnosed but the failure was undetermined. The vehicle was taken to another dealer St. Charles Hyundai where it was diagnosed but the check engine light continuously illuminated. In addition, the contact mentioned while driving, there was a pop noise and noticed white smoke was coming from underneath the vehicle. The contact pulled over to the side and exit the vehicle. The fire department extinguished the fire. A police report was filed. The vehicle was towed to the tow lot and was destroyed. The dealer was not contacted. The manufacturer was not notified of the failure. The approximate failure mileage was 143,000.

This vehicle is consuming large amounts of oil. Up to 3 quarts and 1,000 miles causing the oil light to come on. Hyundai did an oil consumption test with failing results. Due to this they did a deep combustion chamber cleaning. The car still continues to burn excessive amounts of oil. I am told that this does not qualify for the class action lawsuit because it is piston related and not rod bearing related. There is a burning smell coming from the vehicle that does not smell like burning oil. I am highly concerned that the vehicle is going to catch on fire yet Hyundai refuses to do anything about it.

While sitting at a stop light the vehicle suddenly would not accelerate and would not rev the engine above approximately 2000 rpm. Then the check engine light began to flash. I was nearly rear ended because the vehicle just would not accelerate.

The check engine light intermittently comes on, when on the car will stall when trying to accelerate, often accelerate when not intended, and runs rough. A second issue seems to be with the ABS system. On several occasions the ABS systems seems to engage and will not allow you to use the breaks (almost leading to several rear end collisions).

The contact owns a 2015 Hyundai Sonata. The contact stated while driving at 45 MPH and approaching a stop sign, the vehicle started shuddering and stalled. The contact noticed smoke coming out of the hood of the vehicle. There were several unknown warning lights illuminated. The contact was unable to restart the vehicle after several attempts. The contact was able to push the vehicle to the side of the road with the assistance of a bystander. The vehicle was towed to an independent mechanic who informed the contact to take the vehicle to the dealer for repair. The vehicle was then towed to the dealer where it was diagnosed that the engine had failed and needed to be replaced. The dealer sent a claim with diagnostic report to the manufacturer ; however, the manufacturer declined to cover the repair. The contact followed up with the manufacturer and was informed that they could not assist as she failed to complete an unknown software update, under Service Campaign Number: 553, designed to report vehicle imbalances prior to the engine failure. The vehicle was not repaired. The failure mileage was approximately 142,000.

I had a safety recall on my car for the Smart Junction Box. I took the car to the dealership on March 9th 2022. They updated the software that controlls the Smart Juntion Box. On March 11th 2022 at 6:45am I got in a car accident due to the automatic braking system failure. I run into a Ford F-150 at the stop light. Even the brakes at this point failed to work properly as well. I called the deslership and explained what happened to me and I was told by the technician that there is a possibility that the update of the software that runs the Smart Junction Box has impacted the Smart Cruize Control. He said there is a possibility that the Smart Cruize Control settings have been erased to default so the car needed a new settings. That was something I did not know about. My car has the option where you can choose what distance you want between your car and the car in fromt of you. It goes from one-space car to four-space cars. So according to the technician this may has been the problem.
