The Sonata Hyundai Hybrid trunk will not open when the battery dies, and since the battery for the Hybrid is in the trunk, when the battery dies, the car has to be towed because, unfortunately, the key to the trunk has never worked. The last time my battery died, the dealer, after many hours, finally managed to get the trunk open but not without damaging the mechanism. Now there is no way for someone to get out of the trunk if they should get locked in. It's my understanding that a trunk latch malfunction has been a problem with Hyundai Sonata Hybrids for a long time. There is a recall on the newer models. Why not the 2011? The latch does not work. There were no warnings that the battery was low before the trunk became unaccessable.

This car had an open recall fixed a few years ago for EPS (electrical power steering). It is now same issue occurred and has ruined the starter. Mechanic can-€™t even turn it on to fix EPS. Hyundai is refusing to pay for starter. It-€™s due to their faulty EPS system!! So, the car can-€™t even be diagnosed for the EPS because of the bad starter. It-€™s extremely hard to drive and to turn because of EPS recall. It is not safe. They said they-€™d fix it since it was associated with previous recall now they are denying to pay for it. Hyundai case is 18735488. I have escalated the case with Hyundai but no one ever reached out to me. The car is just sitting at the Hyundai mechanic shop until they respond and pay for their faulty parts.

The contact called on behalf of her son who owns a 2011 Hyundai Sonata. The contact stated that the vehicle would intermittently stall and shut-off with the check engine warning light illuminated. Due to the failure, the contact had the vehicle towed on multiple occasions to an independent mechanic who topped off the fluids however, the mechanic was unable to determine the cause of the failure. The vehicle was then taken to a dealer and the contact was informed that the fuel pump needed to be replaced. Upon investigation, the contact linked the failure to NHTSA campaign number: 18V934000 (Engine, Fuel System, Gasoline) however, the Vin was not included. The contact also stated that the vehicle would run hot as the temperature gauge would indicate a rise in engine temperature. Additionally, the contact stated the vehicle failed to start up after several attempts. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

I was on the on ramp of the freeway with the closest vehicle several hundred yards in front and no vehicles behind or on the side of me when my sunroof "exploded". Fortunately the curtain was drawn so no glass poured in the vehicle, but when I pulled over half the sunroof was gone and the remainder in shredded. I do no believe anything struck the vehicle.

I was driving approximately 55 mph on a highway and it started raining. I turned my headlights on and the traction control light came on. I also lost acceleration power until I completely let off the gas pedal. This has happened several times over the last month. I also am unable to set the cruise control if my headlights are on.

Car would not start took it to dealership they said alternator was bad had it took it to mechanic shop paid 300 alternator drove it to car wash car would not start again. Was told it has something to do with push to start and sensor in break pedal. Paid cash for the vehicle drove it from the individual I bought froms location to the store and it's left me stranded ever since. Dealership keeps diagnosing alternator, starter get online and read and there are complaints and even videos on you tube about this same issue but Hyundai refuses to fix it. Wish I had never throw my money down the drain now I'm just out of a car no way to work and don't know what I'm gonna do. Poured every last penny I have into it and it still will not start. Single mother of two children no financial help other than my work income which I may not have much longer if I'm unable to have transportation to get there. Thanks Hyundai what a way to treat customers who's put faith in your vehicles.

On March 1, 2021, I noticed an odd smell while idling in line. Turned car off until it was my turn. The smell was gone once I turned it back on, so thought it was another car and drove to work. That evening, smell started again after driving a few miles to parent's house. Parked the car at parent's and arranged to drive it to mechanic the next morning after having my father confirm there was water in the radiator and the oil wasn't too low. Engine temp gauge was normal. Check engine light was on, but had been for the length of time I had car. I had it checked several times- issue would be supposedly found, but it would always come back on. I was led to believe it was a faulty sensor issue. There was nothing obviously wrong when we looked under the hood and had no reason to think it would not be safe to drive the short distance to the mechanic. Next morning, March 2, 2021, I intended to drive the car to the shop so they could address the issue causing the smell, and father followed behind. Car seemed fine at first, but after a couple of miles driving on surface streets, the smell came back. Pulled over and turned off car, thinking that I would need to have the car towed the remainder of the way. I saw something come from under hood. My father, who had been following behind, asked me to pop the hood. As I climbed back in the car to pop the hood, I realized there was smoke inside the car. I got out, told my dad that there might be a fire as there was smoke inside the car. As we had that discussion, smoke started pouring from under the hood, and we backed away from the vehicle and called 911. Within seconds, there were visible flames and the whole front of the vehicle was engulfed in flame. Today, March 10, 2021, I was made aware that 2011 Hyundai Sonatas were included in a list of vehicles known to catch fire, so I am filing this notification.

The car does not start at random, usually after it has been driven somewhere like the gas station or the grocery store. It cannot be jump-started and pumping the breaks has no effect, the only way to get the car to start is to wait, letting the car sit off for a while, and eventually, an attempt to restart the car will work (note: "a while" can range from anywhere from 10 minutes to 4 hours). The battery and starter have both been tested to be functional and thus are not the culprit. This issue happens regardless of how new the battery in the key is. This issue has resulted in being stranded in some places for long periods of time. This has been happening for 3 years and has started happening with more frequency as time goes on.
