Equipment Problems of Hyundai Sonata - part 2

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.

I was driving my yesterday morning like normal, about 15mph getting off of a freeway offramp, when all of the sudden I heard a strange brief noise come from the inside of the car. I couldn't figure it out so I drove home. Went inside for about 20 minutes, went back outside to leave again and I noticed my panoramic sunroof had shattered/exploded from the inside outward. I had it towed to my local dealer in hopes warranty would cove, but I was told it wouldn't. I have to use aftermarket glass with my insurance company to replace it due to geico not covering oem glass.

Vehicle suddenly accelerated after pulling out of store parking lot at low speed into side street behind vehicle stopped at light (less than a car length in front) while pressing hard on brake. Vehicle lurched forward incrementally during the braking process, but vehicle kept accelerating causing vehicle to hit stopped vehicle numerous times before vehicle engine was finally turned off. Driver of both vehicles could have been seriously hurt. Vehicle was driven home after this incident without incident but has only been driven out of garage and onto and off towing truck. Car has not been inspected except for damage to vehicle and is currently awaiting insurance rep inspection at vehicle repair facility. Once damage is repaired car will be towed to dealership for inspection. Because of the short distance vehicle traveled no warning lamps/messages were noted.

I had engine issues back in 2021. I had to pay $600 for a part to be installed to fix the problem . The engine failed, the idle was violently lurching forward and would randomly shut down. Recently the car shut down without warning again. Its scary.

Recall on paint quartz pearl white my car is peeling and chipping I notified Hyundai because I know many customers also are having this issue and they will not resolve this issue.

My steering rack had to be replaced at less than 55,000 miles. I asked the dealer if this was covered under warranty and they said no. I was charged $4,800 for this repair. I contacted Hyundai USA and they refused to cover the repair. I then realized that I had received a letter from Hyundai stating my car had the extended warranty of 15 years/150m miles for this exact repair. I am on the phone with Hyundai now and they are still refusing to cover this repair, even though they sent me the letter stating my car has this extended warranty. My car is available for inspection upon request. Yes, my safety and the safety of others was put at risk, my power steering would intermittently go out while turning. Yes, my car was inspected twice, once in 2023 and again in may of 2025. Repairs were done in may. I was told this was not covered under warranty but I have an extended warranty from Hyundai for this exact problem. That extended warranty is for 15 years/150m miles. Yes, the occurrence in 2025 threw a code of c168708 - can time out vsm (mdps) and c1814 - can message failure sas.

After a dealer-installed software update on my 2024 Hyundai Sonata sel awd, the car began jerking during acceleration and shifting. This happens at low and moderate speeds and creates an unsafe hesitation, especially in traffic. This issue did not exist before the update. I believe the software update affected the transmission or engine control calibration. The dealership has not resolved the issue, and it poses a safety concern. Please investigate whether this is linked to a faulty update affecting other Sonata vehicles.

P0741 code tcc solenoid.

Bought in 2023 @ 98k miles. Have had trouble with 1. It would only start in drive, then that seems to have self corrected. 2. In drive, car would not accelerate properly, and would slow as though I was braking, but no foot on brake. Had rear brake sensor replaced, seemed better for a while. 3. Developed oil leak at 120 miles which valvoline characterized as "not serious. . . Just keep checking it and topping it off. " so, have been doing that. Today after oil change, it began running rough, lots of vibration, then the shifting problem, sluggishness, and new. . Smoke from under hood on driver's side. No check engine lights at all. Nothing registered as hot or overheating. Turned off car, checked oil and trans fluid, both in proper range for warm engine. Let car sit and cool for an hour. Decided I had parked too close to the propane tanks for a smoking car, so I decided to start car just to back it into a space across the lot. Car had no issues- no smoke, no jerking or vibration, no sluggishness, no phantom braking. This car has done this same thing about once every 6 months since I've had it. Changed a tire sensor, that seemed to fix it once. Stopped using cruise control altogether, that seemed to help once. My brother is an ase certified high school auto mechanics teacher who ran his own shop for 20 years and worked on trucks for vdot for another 7 years and he cannot diagnose it. I know it has something to do with not being in the correct gear, but it's not reliable, and I have a hard time believing it's just my vehicle.

I am writing to formally file a complaint regarding Hyundai’s recall campaign 216, which involves a safety defect related to the windshield assemblies of certain Hyundai vehicles. Despite the recall being issued to address the risk of inadequate windshield adhesion due to non-conforming clear coat paint, I have been unable to get my vehicle repaired. I contacted my local Hyundai dealership promptly after learning about the recall; however, they informed me that they were unable to perform the repair at the time due to not having a glass technician on staff/on site. I made multiple phone calls after anticipating the service manager’s follow up, as she promised, with dates a glass technician could be on site. I never heard back after leaving various voicemails or being put through to the wrong departments. This delay is concerning because the recall notice specifically outlines the increased risk of injury in a crash if the windshield is not adequately retained. As a concerned vehicle owner, I am left driving a potentially unsafe vehicle without any clarity on when a proper remedy will be available. I urge the NHTSA to investigate this matter and ensure that Hyundai and its dealerships are prepared and properly equipped to carry out the necessary recall repairs in a timely manner, in alignment with their safety responsibilities. I have attached the email received 7/31 from Hyundai following my customer service complaint I submitted 7/9. Please let me know if any additional documentation or vehicle information is required.

I purchased a vehicle from cash car network on 4/3/2025. At the time of purchase, the vehicle's odometer showed a mileage significantly lower than what official records indicated. After purchasing, I reviewed the carfax report and the vehicle registration history, which documented that the actual mileage was approximately 270,000 miles — much higher than what the odometer displayed. This discrepancy suggests that either the odometer was tampered with or the instrument cluster was switched from another vehicle without disclosure, which violates federal laws related to odometer fraud (49 u. S. C. § 32701 et seq. ). Additionally, the vehicle experienced multiple serious mechanical failures shortly after the purchase, affecting its safety and drivability. I have since returned the vehicle to the dealership. I am filing this complaint to report potential odometer fraud, failure to disclose critical vehicle information, and the sale of an unsafe vehicle to a consumer. I am requesting that NHTSA investigate this dealership for possible violations of federal odometer disclosure laws. Supporting documentation, including the carfax report and registration history, is available upon request.

My 2017 Hyundai Sonata se is experiencing symptoms consistent with connecting rod bearing failure covered under Hyundai’s ksds extended warranty program. June 22, 2019: ksds software (campaign 953) installed, qualifying the vehicle for Hyundai’s 15-year/150,000-mile warranty coverage for bearing failures. August 2022: campaign 208 engine recall performed. Hyundai’s record shows Aug 15, 2022, while wright way Hyundai’s service history shows Aug 13, 2022 (discrepancy unresolved). March 2025 (100,238 miles): vehicle went into limp mode with tailpipe smoke and loss of power. It was towed to wright way Hyundai, which kept it for several days but returned it with “no issue found. ” the smoke continued. June 5, 2025 (103,996 miles): oil change performed. August 27, 2025: oil light illuminated, dipstick showed no oil. Vehicle now exhibits severe drivability issues consistent with bearing damage. Hyundai has incorrectly tried to reframe this as an oil-consumption issue and directed me to pay $600 for a combustion chamber cleaning. My issue is not oil consumption — it is a bearing-related failure already covered by warranty. Hyundai’s obligations include a no-cost inspection/diagnosis for connecting rod bearing failure, yet I have been denied that process. Despite repeated written requests, Hyundai continues to attempt phone communication instead of email, even addressing me by the wrong name in correspondence, which suggests reliance on standardized or generic responses. I have exclusively maintained the vehicle at wright way Hyundai, following Hyundai’s service schedule. I am resorting to filing this complaint because after weeks of email correspondence, Hyundai’s corporate agent refuses to help and the manager insists on only calling by phone — which I will not answer out of concern they will attempt to mischaracterize or dismiss my complaint verbally. This failure poses a safety risk because the vehicle has lost power suddenly and requiring restart.

My pearl white 2015 Hyundai Sonata sport’s paint is chipping off while im driving causing paint chips to fly which has almost caused me to wreck. This is happening on the trunk roof and passenger front door.

After driving for a few minutes with the sunroof open the wind deflector pulled and nearly off the car. This had been repaired previously under a recall and the repair was simply to re-glue the wind deflector back in place. This had clearly been done before as the dried glue was still on it. The back end of the sunroof nearly came off during this ordeal while we were traveling at highway speeds and it could have killed someone. We were able to close the sunroof once we had stopped, however it was very difficult to do so and required four of us, each with tools that I happened to have in the car at the time. Had we not been able to get the sunroof back closed it surely would have been ripped from the car. Another recall needs to be put into place and an improved correction needs to be put into place.

On 03/14 I was driving down the road the with the sunroof open the wind flap suddenly went to flying making a loud sound I pulled over and saw that it was loose and hanging I went to press the button to attempt to close it and it semi closed. I went and had it looked at and was told that it was broken and could not be closed and needed to be replaced I was told it was a common issue with Hyundais and to contact the company.

The engine violently vibrates and no matter how much I get an oil change it burns so fast and I have to keep adding. It's not leaking, just burning. I plugged in a diagnostic tester and it said that the 3rd cylinder was misfiring. I haven't had the car for very long, and this is not normal. I take good care of it.

My 2004 Sonata which was manufactured 05/07/04. Has front frame corrosion exactly like the 089 safety recall that hyundia issued already for 1998-2003. My car was manufactured a few months later and they are denying the repair because it doesn’t fall in their production dates.

The daw (driver attention warning) system is obtrusive and a distraction to safe driving. The alert makes an audible "beep" and the drivers display lights up with a warning to "take a break". This alert will continue every 5 minutes if on a winding road until the car is stopped and the engine is turned off. When operating the vehicle in a safe manner keeping my eyes on the road and having the beeping and warning lights distracting me is quite the opposite of its intended purpose. In previous year models this could be turned off by the owner. This is not so with the 2024, 2025 models. This is not isolated to this vehicle but a search of the internet will find many frustrated owners all voicing their concerns. A safety alert system should not become a safety hazard. The dealer has no solution. The alert system cannot be turned off or it's sensitivity adjusted. The manufacturer has so far not responded to my complaints.

Paint peeling on hood and roof.

I purchased a 2002 Hyundai Sonata from a private seller who represented the car had about 40,000–45,000 miles. However, diagnostics from o’reilly auto parts showed 278,000 miles, and Hyundai’s system confirmed over 302,000 miles. The title is marked “mileage exempt,” and the seller is not the same person listed on the title, suggesting title jumping. I have repair invoices, diagnostic records, and screenshots of the original advertisement. I believe this constitutes odometer tampering and misrepresentation.
