On the highway, my 2015 Hyundai Sonata suddenly began making a squealing or metallic rattling noise. At first, I thought it might have been something loose inside the vehicle. Within moments, the check engine light began blinking, followed by several additional warning lights and a pronounced knocking noise from the engine area. Immediately after the warning lights appeared, the vehicle entered a reduced-power -??limp mode-?? and began rapidly losing speed, even though the engine was still running. Because this occurred at highway speed while surrounding traffic was traveling normally, I had to pull onto the shoulder to avoid being struck. This created a significant safety hazard. I was stranded for approximately 45 minutes on the shoulder, at risk of being struck by other vehicles passing at high speeds. A tow truck arrived before the highway patrol, and the vehicle was towed home. When I returned home, my code reader pulled two versions of diagnostic code P1326, which is associated with potential engine bearing failure in Hyundai Theta II engines. The issue has since been inspected by the dealership, who confirmed the presence of the P1326 code. The vehicle is currently available for further inspection upon request. There were no prior symptoms that I was aware of leading up to the incident other than the brief squealing/rattling noise and the sudden warning lights immediately beforehand. The failure happened suddenly and without warning, causing an immediate and unexpected loss of speed and creating a dangerous situation on the highway.

I am reporting a recurring and unresolved hybrid system failure in my 2015 Hyundai Sonata Hybrid Limited that poses an ongoing safety risk to me and my family. The issue involves a "Hybrid System Warning -?" Safely Stop and Do Not Drive" message that appears randomly while driving, causing the vehicle to jerking and creating dangerous conditions on the road. This issue first occurred in February 2024 and has persisted through October 2025 despite repeated service visits and costly out-of-pocket repairs. The hybrid battery was eventually replaced after 8+ months of delays, but the exact same warning and jerking symptoms returned in March 2025 and have never been properly resolved. The dealership (Crown Hyundai in St. Petersburg, FL) and Hyundai corporate case management have been unable to replicate or diagnose the problem consistently, and continue returning the vehicle to me in unsafe condition. On October 3, 2025, the same warning reappeared and the vehicle was dropped off again for yet another service attempt. Again on October 7, 2025, I was told to pick up my car, they could not replicate the issue and could not find a code to respond to. To date, I-??ve paid $1,748.65 for a repair (air flappers) that did not solve the issue, and spent months without use of the vehicle, continuing to pay for insurance during that time. I believe this is a defective hybrid propulsion system that meets the threshold for investigation and possibly a recall, given the repeat safety risk and lack of resolution. Please investigate this matter for the safety of other drivers as well.

What the consumer services tried to offer (More Information for case)me, instead of a replaced engine that is under my warranty. They have replaced engines before over the mileage as goodwill warranty, but refuse to do the necessary work because of mileages. KSDS is designed for any mileage, and they put a mileage limit on the vehicles warranty, that not just I, but multiple people purchased; where the justice

While driving, my 2015 Hyundai Sonata 2.0T experienced severe knocking and loss of power due to a KSDS-related engine defect. The check engine light was inoperative, and the engine now makes loud noises and emits fumes. Hyundai declined warranty coverage despite known KSDS issues. This poses a serious safety concern ( I recently purchased the car and been fixing problems every since)

The car got the 993 campaign software engine immobilizer update and it was locked with the keyfob. It still got stolen. Thieves broke the lock on driver side door which deactivates the immobilizer. Car was found and police report was filed. It is available for inspection. Many Hyundais that have had the immobilizer update have since been stolen. The 993 software update is ineffective.

- Ventura, CA, USA

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.

Cracked dash. This is an ongoing issue with Hyuandai since around 2009. Please investigate. Do the research. I normally wouldn't even come on here to complain. This is my 3rd Sonata. Same issue.

On [XXX], my 2015 Hyundai Sonata experienced a sudden and complete loss of power while driving at highway speed on [XXX] 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) 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.

Our 2015 Sonata has experiencing Engine failure several times due to excessive and irregular oil consumption. Our family-??s safety and the safety of others on the roadway were put at risk as the engine slows, shudders and stalls without prior warning and the check engine light does not come on until the vehicle slows and stalls. The vehicle was inspected at a local Hyundai dealership, and they indicated that this is not covered under warranty. Summary of Engine Issues and Failures: 1.May 3, 2022 -?" 68,671 miles (local Hyundai dealer) Check engine light on, shudder; oil change performed. No cause identified. Paid out-of-pocket. 2.August 23, 2022 -?" 75,527 miles (retail shop) Car engines failed on highway, towed to service shop. Valve cover gaskets replaced. Paid out-of-pocket in part and extended warranty paid part of the invoice. 3.April 29, 2024 -?" 109,229 miles (local Hyundai dealer) Excessive oil consumption noted; valve cover gasket replaced again. Paid out-of-pocket. 4.January 22, 2025 -?" 118,341 miles (local Hyundai dealer) Vehicle stalled en route to airport, towed to dealership; dealership advised oil change. Paid out-of-pocket. 5.May 20, 2025 -?" 122,000 miles (local Hyundai dealer) Engine codes P0300, P0302, P0303 identified. Dealer diagnosed excessive oil consumption likely due to ring wear or sticking rings, contributing to spark plug misfires. Recommendation: Engine replacement. Despite consistent and timely service, including multiple visits to the Hyundai dealership, the root issue has not been properly addressed. The current diagnosis of internal engine failure is a clear continuation of a pattern of unresolved engine problems (stalling in motion, oil leaks and oil consumption) all of which originated well within Hyundai-??s original warranty. The vehicle has been well maintained, and all recalls have been addressed in a timely manner. Hyundai-??s failure to acknowledge and take responsibility for this widely documented engine issue is a safety concern.

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.

To whom it may concern, I was driving on the highway with my sunroof down as the weather was nice. I started to hear a flapping sound and got off at the next exit. I tried to close the sunroof but it would not close. It looked like the windshield thing for the sunroof detached on the passenger side and blocking it. A minute after I started to drive the sunroof panel detached and flew off my car. It shattered on the street in front of another car that was driving behind me. This car had to swerve to miss being hit. I immediately called the Hyundai dealership crying and the women promised me a manager would call me back. I told the lady I dont know what to do. Do I call the police because a 30-pound glass panel is shattered on the street" Do I call my insurance? She said she would have the sales manager and service manager call me back. I was so shaken and scared from the event I called out the rest of the day from work. I had to uber my son home from school because I was nervous to drive the car. If I didnt get off the next exit; would my sunroof have flown off and caused a car accident? It was really scary to see the panel fly off like paper and almost hit another car. That I could have cause another person to have an accident and they couldve gotten hurt. The whole thing is just crazy to me. I did not get a call back from hyundai yesterday. I will try to reach them today. I will uber my son to school this morning as one of the pieces is sticking out and still flapping. When I looked up the recall on my car for this; I could not believe that the hyundai fix is super glue" This car really is glued together.... Thank you to listening to my concern and you can reach me anytime at [XXX]. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased a 2015 Hyundai Sonata. Two years ago, I'm having issues with my car paint peeling off in the hood, roof and trunk. Many times I when to the dealer to ask them about the recall, and they state that there is nothing they can do since they did not have anything registered for a paint peeling recall. My car day by day is getting worse and I need help for this issue to be fix.

My 2015 Hyundai Sonata with Quartz White Pearl paint continues to peel off my car and cause me to swerve thinking that there is something coming at my car like a bird due to the paint peeling so fast. This is also a concern for drivers behind me as my roof pain is peeling and may fly into their line of sight/vision which could potentially cause an accident.
