SUSPENSION, STEERING
My 2009 Hyundai Sonata was taken to the Hyundai of Lincolnwood dealership on May 19th. The certified technician formally diagnosed severe structural corrosion on both front and rear subframes (engine cradles), declaring the vehicle completely unsafe to drive. The dealership is withholding the vehicle under safety custody but refuses to provide a loaner or rental car. Hyundai Motor America states the replacement parts are on indefinite backorder with no ETA, leaving me stranded with no safe alternative transportation since May 19th. This severe structural corrosion poses an imminent risk of suspension failure while driving

SERVICE BRAKES, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
Brakes seize up while driving and then cannot move the vehicle. This causes a dangerous situation while driving and then breaks lock up and cannot move car even though vehicle is on and then stopped for a stop light. Car must then be turned off and sit for about 30 minutes so it can unseize and when that happens, you can then resume driving and then check engine light comes on. Brake lights were staying on even when vehicle is shut completely off. ABS and ESC lights stay on consistently and never turn off. Vehicle brake switch was replaced at Carolina Hyundai of high point, NC. So break lights have been repaired. They had to order the stop switch lamp replacement for recall as it was never done and will be fixed in next week. 3 door handles fell off and cannot open the rear driver side door at all. Window electric system won’t let windows go up and down and had to make a latch pull string to open driver door. Passenger door will not open at all and no handle and is a dangerous situation. Break switch not being replaced would have cause an electrical fire and is a complete dangerous vehicle even after being inspected less than a week ago

ELECTRICAL SYSTEM, ENGINE
Engine leaking oil from the front cylinder bank’s valve cover or leaking from the valve cover’s gasket onto the alternator. A sufficient amount of oil could damage the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. If the vehicle is continually driven with a disabled charging system, the engine can shut off, increasing the risk of a crash.

SERVICE BRAKES
Brake Calipers are getting stuck often damaging the rotors and pads. This happens even for new calipers and rotors that won't last more than one year after replacement. The parts were original from manufacturer. The rear and front brakes were randomly getting stuck on one wheel after a period of using brakes. This put the vehicle in danger of getting fire from overheating rotors or increasing the risk of a crash because of an unusable brake system. This incident has repeated over time from 2017 till 2025 inducing big spendings for fixing brakes

UNKNOWN OR OTHER
Excessively cracked dashboard. The entire dash in my 2009 Hyundai Sonata is cracked and a replacement has been denied by Hyundai USA. A cracked dashboard could cause reduced structural integrity. The dashboard is a structural component designed to help absorb and distribute some of the forces in a collision. Cracks can compromise this ability to perform this function potentially increasing the force experienced by the occupants and the and other parts of the vehicle. It can also cause increased risk of debris and shrapnel. During a collision the cracked dashboard may break apart more easily causing sharp or jagged pieces to become projectiles inside of the cabin these fragments can pose a serious injury risk to occupants. It can also result in an impaired airbag deployment. Many vehicles have airbags in the dashboard a severely cracked dashboard could obstruct or improperly deploy airbags for example the air bag may not fully deploy reducing its effectiveness and the dashboard may puncture or otherwise interfere with the airbag as it inflates creating additional safety hazards. Cracks may expose sharp edges or materials under the dashboard which could harm occupants during a collision, especially in areas where passengers may come into contact with the dashboard. A cracked dashboard could also cause a compromised electrical system dashboards house numerous electrical systems, sensors and controls cracks could indicate underlying damage to these components. In a collision these systems may fail or behave unpredictably which could further reduce safety features. Cracked dashboards present a significant risk during a collision and should be addressed by the manufacturer promptly to ensure its customer safety.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I see that the manufacturer has an "Open Service Campaign" on their Sonata's shark fins. I've taken mine to the local dealership and they want a min. $700 to replace the shark fin. It just came off somewhere (a couple of years ago) and, now, my car has to be jumped off if I let it sit more than two days. I have had it inspected by the dealer and an individual garage. No one would tell me what was draining my battery. I am a senior citizen and fear I will get stranded on the road somewhere. The missing fin lets water into my car, soaking the carpets, etc. Finally, it was suggested that the car cover I keep on it touches the exposed fin components and that's what was draining my battery. It seems that the manufacturer was aware enough of this faulty part to want to prevent complaints by voluntarily replacing problematic parts (thus the service campaign). And, there are a lot of videos on YouTube from DIY folks who've suffered through replacing the shark fins (many different models) themselves. It seems, however, the manufacturer only notified dealers with said "open service campaign," not the public, as in a proper Recall process. That way, they get to make more money off the public when the part falls off? Please advise how one might get the dealers to do the right thing. Thank you.

ELECTRICAL SYSTEM, POWER TRAIN
We purchased this vehicle used 9/2022. A week later it began to jump upon accelerating and slowing down. We took it in and they said it was the power train control module and our warranty would not cover it. So it would cost us around $1600. We can’t afford that. We have only driven it a few times since. We were parked in front of a curb and the car accelerated us into a curb. Now, the ESC OFF, ABS, and engine light are illuminated. This is not a. It also wear and tear issues, as I’ve seen many others posting similar experiences. Our car is an ‘09 with almost 90,000 miles on it.
