2011 HYUNDAI SONATA Complaints

The contact owns a 2011 Hyundai Sonata. The contact stated that while driving at an undetermined speed, there was an abnormal rattling and ticking noise detected. The air bag warning light illuminated. The vehicle was taken to the local dealer where it was diagnosed that an engine replacement was needed. The dealer requested the maintenance records but denied repair coverage due to old oil in the vehicle. The manufacturer was not contacted. The approximate failure mileage was 180,000.

My husband was accelerating onto a highway and the engine failed. He was able to pull to the shoulder and brake to a stop. He was not able to start the car. He had the car towed to our mechanic and the mechanic reported that the engine seized, the engine had oil in it, and we needed to bring the car to the dealer to have it looked at. There were no lights, sounds, or warnings that there was a problem with the engine. This is the second engine failure for this car. The first failure was a fire and the engine was replaced. The dealer stated that it would take 3 weeks before they could look at the car. We brought it in 3 weeks later, 12/19/22. No-one has looked at the car. We don't know what the problem is, because they still have not looked at it.

EPS and traction light came on when driving around 20mph making the wheel stiff and barely able to turn. Looked up 2011 Hyundai recalls and came across recall 143 regarding the steering column. Took car to dealer and they said no recalls found for my vehicle. I told them about what I found online and that I’m experiencing the same issues so I’m not sure why my 2011 wasn’t affected. They basically said too bad too sad. They still have my car so I’m hoping that they figure out my car should be apart of the recall campaign.

ENGINE SEASED UP OUT OF NO WHERE IN THE MIDDLE OF AN INTERSECTION NO SOUNDS NOTHING JUST STOPPED RUNNING

The contact owns a 2011 Hyundai Sonata. The contact stated while driving 65 MPH, the vehicle failed to accelerate and inadvertently decelerated to 10 MPH. The vehicle went into LIMP Mode. The check engine warning light was illuminated. The contact pulled over and had the vehicle towed to the dealer. The dealer diagnosed the vehicle and retrieved fault code: P1326 (Knock Sensor Detection System) and performed an engine bearing test, which the vehicle passed.

The airbags in my car did not deploy! I was hit so hard through my driver window that it knocked me out both speeds combined together was 110mph with me going 55mph the air bags should have went off the whole driver side back to the trunk is damaged and not even the door airbag had went off. This is a huge safety concern for myself.

2020 wiring harness overheated and melted - replaced taillight 6 times in 1 year. Hyundai fixed. 2021 tailight out again - Hyundai stated the taillight assembly melted, needs to be replaced (403.00) light bulb cannot be replaced (warped). Safety issue is what is causing things to heat up and melt. Many others reported same issue online - Hyundai is not taking ownership to fix whatever is causing this? No warning lamps.

My engine has failed, and my steering wheel column has locked. I had the software update on my engine with Napleton that qualified me for a lifetime engine replacement. I submitted maintenance records for my car and pictures of my valvetrain that are well maintained, and hyundai denied my engine claim for exceptional maintenance neglect on Dec8. On December 14th, after reviewing my oil changes, they still denied me for using low quality oil that's obscured. The problem I am having with my car is oil, not being able to get to the pistons inside my engine. It's not fair when the company know they engines have a manufacture defect. Then they blame the customers for lack of maintenance to have an excuse not to replace the engine. Knowing that with or without oil changes in the hyundai sonata 2011 -2012 models the engines will eventually seize anyway.I've reached out to their company over 300 times trying to resolve this matter and I'm still in the same place I started at a month ago. I want to sue for pain and suffering. I've been without a car since nov 9, and it's dec 20. Hyundai has put me and my family life in danger on numerous occasions, with their faulty and defected parts causing two near death experiences. Hyundai sonata has had a recall on every part, and I consider them unsafe and dangerous. I have seven different case reports with Hyundai motor company about excessive oil consumption, and the knocking whining vibrating and shaking. They are very much aware of everything

I started smelling a strong fuel odor and my car just started leaking fuel while I was driving it.

When Driving the Alarms go off indicating a brake issue, my brake peddle goes to the the floor, car looses power and slows down to 5 MPH. Car will not accelerate past 5 MPH when i am trying to pull over or get off the freeway. Brakes are grinding as i try to use them, very dangerous while on the freeway. When I am able to pull over. I will turn off the car and turn it back on and the issue goes away. Now this may happen several more times before i am able to get some where safe. Dealership has no clue why its doing this after showing the video of the Alarms and describing it. No codes are found either. They just want to start replacing parts stating at 3k a round hoping it will fix the issue. This issue doesn't happen every day but it does happen while driving on the freeway. I have read online others having the same safety issue while driving and having thes same brake failures. Not sure where Hyundai is at with this issue and the fix for it? Yet does someone have to be in a serious accident before someone takes action with this issue?
