Equipment Problems of Hyundai Sonata - part 1

I have had 3 door handles fall off in the last couple months I think this is safety concern I do not see any recalls. I do see that there is a lot of people complaining about this matter door handles should not be fallen off.

Car has had check engine light on for 3 + years. Have taken it to several mechanics including a Hyundai dealership and none of them can figure out what is wrong. Have replaced water pump, belts x2 in a year (same belt) and thermostat x 3 again (all within 2 years). Dash fuel gage and dash heating/cooling gage are completely erratic. Cruise control does not work. Due to chronic check engine light and mechanics unable to pin point the problem, car has become hazardous to drive. With that in mind, today (9/10/2025) while exiting the high way, car stalled and behaved like it was in neutral. Steering wheel also locked up at this time. Luckily was able to stop. Had to restart car and then it occurred again while driving on a side street at 35mph. The codes that are still popping up are ones that I have spent thousands trying to fix and find the root cause of the problem. What could the issue be if no mechanic can seem to diagnose and fix the issue?.

The vehicle had the antitheft recall service done. On 8/30/25 the vehicle was stolen. It was recovered on 9/1/25 without the catalytic converter. The insurance confirmed it was a total loss. The door lock was tampered along with the engine lock. This was a horrible experience.

The parking assistant camera on the front of the car is loose, which means that the bracket is broke. I took my car into Hyundai and they could not explain to me how it got broke or came loose and this is a safety issue because this helps you park and see what’s in front of you when parking.

I got this car a Hyundai Sonata 2004 about 2 to 3 years ago. At first I didn't notice the problem until a couple months into me having the car I was on the freeway and it suddenly felt like I was out of control of my car and the back end was like swerving like I was pulling a trailer. And ever since then it's gotten worse now my front right tire goes flat randomly. A friend mechanic of mine looked at it and said that it is a suspension he just doesn't know what part of the suspension. This is dangerous because I could lose control of my car I have at any time. That could be detrimental and there is a recall in it seems like almost every other state but utah. For the exact issue that I'm having and I don't think that's right. I've had issues with this car ever since I got it. If you guys could look into this that would be great also this form asks the approximate date that something happened it happens all of the time. To the point where I'm afraid to drive it at all. I also it's gotten so bad that sometimes when I'm going only 35 mph and I hit like a pothole it will severely swerve and I will lose control of my car or if I turn my car I turn my car my steering wheel the right way and I lost control of my car it started swerving and I was on a mountain. .

The vehicle went in for repair at the dealership early July for a check engine light and dtc error code. It was revving high after being driven for more than 20 min or so and wouldn’t get to above 60 mph. Jerky, dangerous acceleration and deceleration seemingly out of nowhere. The dealership replaced the fuel pump which is what they said was causing the error. Today on August 10th, check engine light popped up again with a dtc error code. Weird acceleration and deceleration and general jerkiness when driving. Scheduled service appointment for next week.

What component or system failed or malfunctioned, and is it available for inspection upon request? the engine in my 2017 Hyundai Sonata sport is defective. Oil pressure failed testing, oil contamination was found on the oil pressure sensor and connector, and the vehicle has experienced excessive oil issues. The engine is still in my possession and available for inspection upon request. How was your safety or the safety of others put at risk? the vehicle has gone into limp mode on the highway, which caused a sudden loss of power and created a dangerous situation in traffic. The car also shakes, misfires, and loses power unexpectedly, which could lead to stalling or loss of control at highway speeds. I do not feel safe driving the car. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Multiple Hyundai dealerships have inspected the car. One confirmed low oil pressure and oil contamination at the sensor. Previous visits dismissed the oil warning and charged me for oil replacement instead of identifying the underlying defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes. The vehicle has been inspected by Hyundai dealers multiple times. I also have two inspection reports from the same dealer just two weeks apart with contradictory findings the first showing no oil issue, the second confirming oil contamination and failed oil pressure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes. The oil warning light and check engine light have both come on. The vehicle has gone into limp mode, and symptoms have included shaking, misfiring, rough idling, and loss of power. These issues began months ago and have continued despite repeated service visits.

My Hyundai consumes oil and I have to put oil in it every two weeks! also my ignition coils has had to be changed 4 times. Also check engine light just came on code saying catalytic converter or oxygen sensor changed oxygen sensor a couple months ago. I purchased it brand new and as soon as I got over 100,000 miles nothing has been going good since then please help also my paint on the top of the car is starting to peel. Will never buy a Hyundai again.

My starter failed after 35,683 miles leaving me stranded in a parking lot at night. The life expectancy for a starter is between 100,000and 150,000 miles. Hyundai replaced the part at a cost of $1,139 which is way above what it normally costs to replace a starter. The starter is at the dealership and is not available for inspection. Being stranded in a parking lot made me very uncomfortable and what if the starter had failed in a bad section of town. The problem was confirmed by a Hyundai dealership who replaced the part after I had my vehicle towed to their service department. The only ones who inspected the vehicle was a mechanic at the dealership. There wer no warning lamps or messages, but I did notice the car did not start on the first try before the starter failed. 07/29/2025.

There are 2 cracks on the dashboard directly over the passenger airbag that were there when I bought the car and there is another crack that happened some time between yesterday and today. The crack is almost the width of the dashboard. If there is an accident I'm worried about get hit by pieces of plastic dashboard.

I recently got a radiator replaced and now my car won't reverse.

I have contacted the guy that sold me the car he refused to fix the recall which is my motor I need something done , Hyundai won’t honor their recall .

When starting car warning lights came on for abs, aeb, cruise control. Cruise control is locked out and not working due to these warnings.

I started the car, put it into gear and then the breaks wouldn’t work. The car dash said something like check breaks hybrid system failure do not drive. There is not recall on my car but the Hyundai service department doesn’t know how to fix it. This is the second time it’s happened. I’m scared to drive it. Please investigate!.

The inattentive driving warning goes off excessively, causing distraction even in heavy traffic. Over a 2 hour drive, the inattentive driving warning would alert approximately every 30 minutes regardless of traffic or driving conditions. The sound, which lasted approximately 1 to 2 seconds, and alert display caused me to momentarily turn my attention to the instrument cluster, rather than the road, while I was traveling at highway speeds in variable traffic. Previous model years allowed you to turn off this function, but this is no longer the case. Hyundai even confesses the inaccuracy of the system within the manual and has sent out notice of ways to lower incidences on different models vehicles.

Check engine light keeps coming on got it looked at , certain parts replaced & it’s still on something to do with the air filter.

Vehicle dashbaord has been facing uv related reactive damages by small line cracks and now it's progressing to larger lines. Similar damages in other manufacturers like Toyota and Lexus are covered by manufacturer as recalls .

1. Sunroof disengaged from car. Yes 2. Glass falling from car. Glass could have landed inside car, killing or injuring driver. Glass could have landed on any car behind the Sonata killing or injuring occupants in that car. 3. Unknown 4. No 5. No.

All documents are attached as it is many separate incidents that ended knock from motor and minutes later, a piston shooting through the engine block which is what made the car inoperable.

The moon roof made a very loud noise as I was driving down the interstate. It sounded like a loud bang. The safety risk was that I could have jerked the wheel from the scare of the loud sound. My moon roof then shattered and began to fly off.

My dad gave me his car a little bit ago, and I just learned there is a cap and sensor part in the engine that fills with oil which triggers the check engine light. I nearly got hit because I didn't know the car couldn't accelerate properly when this happens. My neighborhood exits onto the main road at an incline and my car wouldn't move faster than 10 mph while cars were coming behind me at 45. I was terrified. My dad told me had the same problem. He took it to the dealership to be repaired when it happened to him and they said it was fixed, so apparently it is a reoccurring problem.

I bought this car in June 2013 for its safety and its amazing warranty and all the features that it has Hyundai manufacture had an obligation as a consumer service and failed to send notification of any recalled to us in regards to a recall high pressure, fuel pump, and fuel rail fuel system engine, gas tank this is a product of liability and negligence on time but they failed to take responsibility and comply with federal laws. I was driving with my family in the car when this car was a ticking time bomb not even being aware of the death trap on wheels. We ended having towed our home and then to then had to make a call next day and have it towed to Hyundai service center while we were driving this happen, where we heard two loud pops the gas gauge went down from 200 something to 80 engine lights came right up the backseats were heating up under my son seat in the back stated he felt waves as the backseat was getting hotter, we pulled over to a gas station and that’s when we had to call called o’reillys and then we called a mechanic friend which stated that he ended up looking up the car and stated please pull over and get out car and called the Hyundai manufacture that there was a recall that’s the only way we found out other than that no prior incidents, then called the service technician of Hyundai I called amd complaint with the Honda manufacture corporate. They have failed to take the responsibility for this and they should be ashamed and take their accountability for this we could’ve died and anyone else around us on road as we drive this car daily the car was a higher risk of a ticking time bomb stated by the Hyundai service center technicians. This is an nere to miss accident narrowly avoid catastrophe.

On June 4 as son was turning, the car started shaking & went to park. He managed to slip into a nearby parking spot & tried to reverse. The car turned on, put into reverse & then after about 2 seconds it went to park & stopped. This happened several times. It was towed to the dealer who today, June 10, reported it was a transmission flaw. The car was being driven at about 30 mph on a 2 way street. Had it been on the interstate at a higher speed, it may have caused a dangerous situation with a sudden stop.

I have a 2013 Hyundai Sonata 4 door sedan. I am unable to open the driver's left hand door to exit the car after turning off my vehicle. Only way I can open door to exit is to lower the window while motor still running, reach outside and grasp door handle from outside to open and push/pull handle which doesn't allow me control over the door. Then I have to raise window with door standing open before I am able to turn off the ignition and exit my car. In case of an emergency this is unsafe for driver and passengers. In this instance, I was trapped inside a hot car in texas summer heat. In another instance, I could have had an accident and would have been unable to exit to safety. I searched for recall to this model which is covered for Hyundai Sonata manufactured in other years but my vehicle 2013 make is not included in same recall for exact same issue. There was no warning lamp, messages prior to failure. I have googled this "condition" and learned that this is a common problem for Hyundai Sonatas.

On may 28, 2025, my 2015 Hyundai Sonata experienced a sudden and complete loss of power while driving at highway speed on I-75 in sarasota, FL. There were no warning lights, error messages, or abnormal performance indicators prior to the failure. Within minutes of losing power, smoke began to enter the cabin, followed by visible flames from the engine compartment. I pulled over, exited the vehicle, and called 911. The fire fully engulfed the vehicle and destroyed personal property inside, including my late father’s ashes. The incident caused significant emotional distress and has resulted in a ptsd diagnosis. The sudden nature of the failure and rapid spread of the fire suggest a critical defect in the vehicle’s engine or related components. I believe this represents a serious safety hazard to other Hyundai owners and the public. Documentation, photographs, and insurance/fire reports are available.

Formal complaint – hybrid system failure, safety risk (VIN: [xxx] | Hyundai case #[xxx]) dear sir/madam, I am writing to file a formal safety complaint regarding a dangerous incident involving my Hyundai hybrid vehicle (VIN: [xxx] ) and Hyundai motor America's failure to respond meaningfully to repeated requests for assistance. Incident summary: on [xxx], while driving with my two young children (ages [xxx] and [xxx] ), my vehicle suddenly displayed the following critical warnings: “hybrid system warning! safely stop and do not drive” “check charging system” immediately after these messages appeared, the car lost all power and came to a complete stop in the middle of the road. This created an extremely hazardous and distressing situation for me and my family. Although the vehicle is a few years old, it has very low mileage (38,345 miles), and I did not expect such a catastrophic failure. I submitted a report to Hyundai customer support on may 30, 2025 (case #[xxx]) and followed up on June 9, 2025, but have only received an automated acknowledgment—no response, investigation, or support to date. Attachments: a video clip showing the warning messages at the time of the incident (I cannot upload the video clip since the option is not there, but I do have it if required) requested actions: a formal investigation into the safety and reliability of Hyundai's hybrid systems. A determination as to whether this incident qualifies under Hyundai’s warranty or federal safety defect regulations. Immediate contact from Hyundai with the next steps regarding inspection, resolution, or compensation. I am cc’ing Hyundai motor America to ensure this matter is escalated appropriately and receives the attention it warrants. Thank you for your time and consideration. I look forward to your timely response. Sincerely, [xxx] [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The gear shifter design on this Hyundai model is dangerously counterintuitive compared to industry norms. It nearly caused me to drive off a cliff. I encountered a serious safety issue with the gear selector design. In most vehicles — including mercedes, gm, and even pickup trucks — pushing the gear selector down engages forward drive, and up engages reverse or park. Hyundai has reversed this logic. In a rushed moment, I instinctively pushed the shifter down expecting to go forward (as in most cars), but the Hyundai was in reverse. I stepped on the gas and nearly backed off a cliff. This design is not just unfamiliar — it's opposite of established standards. Drivers with muscle memory from other vehicles like any pickup truck, mb, or gm ev are at real risk of making fatal errors. I strongly urge NHTSA to investigate whether this shifter design meets safety and human factors standards. At a minimum, Hyundai should issue a ui/ux recall to standardize shift direction or implement safeguards to prevent this kind of mistake.

Rearview camera fails to display an image. It does work sometimes but then most of the times the rearview camera does not display any image as seen in the images attached. This issue started occurring recently, that is when I reverse the car, the rearview camera image is not displayed at all. Earlier the rearview camera was working with out any issue when I reverse the car. Issue seems to be same as campaign number: 24v879000.

My car is burning a lot of oil to the point I have no oil in my car and that’s bad.

Multiple critical mechanical and safety issues have occurred with my 2018 Hyundai Sonata sport. The vehicle has experienced persistent engine misfire, a severe oil leak, emissions system failure, and extensive paint deterioration. A certified technician confirmed an active oil pan leak with no dashboard warning lights, posing a fire and stalling hazard. To prevent further damage, I replaced the entire oil pan and spark plugs at a personal cost of approximately $800 at firestone complete auto care. The check engine light revealed diagnostic code p0420 – catalyst system efficiency below threshold (bank 1). An o’reilly emissions scan confirmed the catalytic converter failure, and emissions status was marked “red. ” the vehicle will not pass an obd-based emissions test. At 149,219 miles, Hyundai refused warranty coverage due to mileage. A certified Hyundai dealership quoted $3,722 to replace both the catalytic converter and valve cover gasket, which remains unaffordable and unrepaired. In addition, the factory-applied white paint began peeling severely from the hood and roof. Although Hyundai issued a warranty extension for this known defect, the dealership refused to repaint the hood, citing a minor dent — even though the peeling is clearly unrelated. The exposed metal has started to rust, risking structural deterioration. All concerns have been evaluated by certified Hyundai service and independent professionals. These combined mechanical, emissions, and exterior failures raise serious safety and durability concerns. I am filing this report to document manufacturer-related defects that may affect other owners of this model and year.
