2012 Hyundai Sonata: doors won't lock, open or latch

Filed Oct 25, 2024 · Body · SC

The passenger rear door will not open from the inside OR the outside. The door lock on the inside of the car will not open. Door is in locked position. Problems like this are all over the internet regarding Hyundai cars. This is a safety issue because someone in the back seat can NOT open the door and are potentially locked inside the car with no way out. This could be life and death if there was a fire, accident, etc. Independent repair center has inspected and confirms. No warning lights. Just happened in September 2024.

My hyundai sonata 2012 recently experienced engine seizure on a 5 lane highway in nj garden state parkway at 70 MPH without any warning what so ever.car was checked for this recall year ago and supposedly software was installed to notify if engine was to fail. There was no warning! Dealer confirmed the engine died and is covered under the recall. I also had mentioned concern about the noise under the car. They replaced the engine & serpentine belt and told me to come back in 3 days as it was too early to do the inspection. When I got the car back the noise was still under the car, the tire light came on, back door lock stopped working and AC stopped working I called back and they told me $1500 worth of work to pass inspection. 3 days earlier they said the car was good to pass. Including continental tires that hyundais horrible suspension ruined at 16k miles(tire warranty 70k miles) and both sway bars and sway bar link. Which means I could have rolled the car at any curve.axles were changed twice on this car as they told me " manufactory faulty" axles they put on and other suspension parts. Tires were rotated and aligned by them! If that's not good enough person working on my car damaged both of my front doors when letting the car off the lift.then the dealer tried to cover up the damage and sign me the car back! Car has some serious electrical issues with interior/exterior. Lights melting, bulbs burning and now the car doors locks. Better yet new recall says if you had your engine replaced you are in a danger of the fire.how am I supposed to trust this "certified dealer" ? + the other 8 recalls and class actions about this car- hyundai needs to be forced to buy back these all of these cars. Not only is that not safe for me its also not safe for other drivers! I've also been without my car for about a month at this point.

On june 8th, 2018 my husband was driving down interstate 85 in charlotte nc going about 60 MPH when the vehicle stalled. He coasted the car to the side of the interstate. He turned the vehicle off then tried to restart it and nothing happen and power was dead in the car. Then he saw smoke coming from under the hood. The doors won't open so he had to climb out though the sunroof to safety. He opened the hood and the engine was inflamed with fire. He called the fire department, they came and put the fire out. The reason I'm filing this compliant is because he could have been seriously hurtor killed if the sunroof was close. Hyundai has no explanation for why this is happening and my vehowas total lost. We also have pictures and a video. I can't upload the video so if someone contacts me I will email it.

Key fob in 2012 hyundai sonatas not recognized and don't allow you to start up your car using the push/start button; also, doors won't unlock with fob and manually have to be entered using actual key. Seems like some programming to the fob has been lost; dashboard would turn on and say"key not in vehicle" or "insert key" when depressing the push/start button. Apparently, dealerships are aware of the problem, but may not actually report it and treat as something else only after numerous other repairs. Youtube videos of these issues as I've described are available. Vehicle is stationery when this happens; then it would work and then stop again in a few days. Changed batteries in both fobs and still the same issue. Originally starting happening a week prior to 9/27/2018.

Around 60,000 miles, my driver's side brake light harness melted and had to be replaced. Around 80,000 miles, my passenger brake light harness melted and had to be replaced. Around the same time, 80,000 miles, my automatic door lock master switch began failing. I'm wondering if there's an electrical flaw causing these problems. Perhaps the writing doesn't hold up in hot climates, I live in a desert where the car is subject to temperature up to 140f as it is parked in direct sunlight. I notice more malfunction with locks on extremely hot days.

The paint is chipping away in the exterior by the door handles and the steering wheel. Also the driver seat material is starting to fall apart as well as the door trim on the driver's side.
