Me and my friends are actually going to a trip on three cars. And I am the only one driving my car. All of a sudden when I am on US Highway 82. It started smoke. Immediately I tried to pull over. With in seconds it started fire. I inhaled lot a of smoke. I am a asthama patient so felt dozy immediately. Somehow I immediately came out of the car. I called 911 and whitesbore pd and fire engine team immediately arrived. But with in that time the front hood completely burnt and front seats as well.
The vehicle suffered an abrupt, internal engine seizure while operating in active traffic at highway speeds. This sudden loss of power created an immediate crash hazard, as the vehicle decelerated rapidly in the travel lane, narrowly avoiding a rear-end collision and putting my family and other motorists at extreme risk. The vehicle was towed immediately to an authorized Hyundai dealership service center where it is currently awaiting the physical recall inspection. Prior to the complete engine failure, there were no warning lights, abnormal gauge readings, dashboard messages, or noticeable performance symptoms. The engine seized completely without warning. The vehicle has an open, uncompleted Federal Safety Recall 162 (NHTSA Campaign Number: 16V729000) for this exact engine manufacturing defect and bearing failure.
I am submitting this complaint because I believe this issue presents a serious safety concern. My 2014 Hyundai Sonata experienced a failure related to the steering angle sensor, causing the ESC, ABS, and traction control warning lights to illuminate while driving. As a result, these important safety systems lost functionality and were no longer available to assist in maintaining vehicle stability and traction during normal driving conditions. This failure occurred without warning and required replacement of the steering angle sensor, followed by a required calibration. A critical steering-related component should not fail under normal driving conditions, especially when its failure can disable multiple electronic safety systems. Drivers may not immediately realize that these systems are no longer functioning, increasing the potential risk during emergency maneuvers, wet road conditions, or sudden avoidance situations. While researching this issue, I found that many other Hyundai owners have reported similar steering and electronic stability control problems. I respectfully request that NHTSA investigate whether steering angle sensor failures, related steering system components, or the associated calibration requirements represent a widespread defect affecting 2011–2014 Hyundai Sonata vehicles. If this issue is determined to be common, I ask that Hyundai be required to address the defect through an appropriate recall or extended warranty program so owners are not responsible for repairs involving a critical vehicle safety system.
The check engine lights blinking, it overheats and it shuts down.
I was driving my 2014 hyundai sonata that I only had for 3 months when it just quit on me. I pulled over and seen when white smoke was coming from the wires.
Updated NHTSA Complaint DraftVehicle Information: 2014 Hyundai SonataVIN: [XXX] Incident Date: XXX Description of Safety Defect:While driving on XXX, the vehicle's engine experienced a catastrophic mechanical failure and completely shut off without warning, causing an immediate loss of motive power. This sudden engine stall created an extreme, hazardous traffic safety risk.A subsequent professional inspection revealed that the vehicle's odometer had been illegally rolled back and tampered with by the selling dealership (Johny's Auto Center in 120 bleu hill ave Roxbury, MA) 02119 prior to purchase. The true, undocumented mileage of the engine is significantly higher than indicated, directly causing this sudden component failure. I am reporting this incident both as a critical vehicle safety defect and as a case of illegal odometer fraud. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I am submitting this complaint regarding a serious safety issue involving my Hyundai Sonata. While driving under normal conditions, my vehicle suddenly entered a low-power ("limp") mode without warning. The vehicle would not accelerate beyond approximately 30–35 mph, creating a potentially hazardous situation in traffic. At the same time, the check engine light began blinking. The sudden loss of power significantly reduced my ability to maintain traffic speed and safely maneuver the vehicle. This condition could have increased the risk of a rear-end collision or other accident. I brought the vehicle to an authorized Hyundai dealership (Fred Beans Honda Of Abington PH# 215-392-9020) for diagnosis. The dealership confirmed that the vehicle stored Diagnostic Trouble Code (DTC) P1326, related to the Knock Sensor Detection System (KSDS). According to the dealership, the vehicle entered limp mode as a result of this fault. The abrupt reduction in vehicle power and speed occurred without sufficient warning and created a safety concern. I am reporting this incident so that NHTSA can investigate whether this condition represents a broader safety defect affecting Hyundai Sonata vehicles equipped with the KSDS system. Vehicle Information: Make: Hyundai Model: Sonata Model Year: 2014 I request that NHTSA review this issue and evaluate whether additional action is warranted regarding vehicles experiencing DTC P1326 and associated limp-mode operation.
Vehicle Information: Year/Make/Model: 2014 Hyundai Sonata Mileage: less than 120,000 miles Ownership: Second owner Complaint: I am filing a complaint regarding a serious engine failure in my 2014 Hyundai Sonata. My vehicle experienced issues beginning with a faulty knock sensor, which escalated into complete engine failure. This issue appears to be identical to problems that have already been identified in recalls involving similar Hyundai Sonata models. Despite experiencing the same symptoms and failure pattern, my specific VIN is not included in the recall. My vehicle has been well maintained, has under 120,000 miles, and should not have experienced a total engine failure under normal conditions. Based on the known recall issues related to engine defects and knock sensor failures, I believe my vehicle is affected by the same underlying defect. I am concerned that vehicles like mine are being excluded from the recall despite having identical safety-related issues. Engine failure while driving presents a serious safety risk, including potential loss of power, stalling, or inability to accelerate in traffic. I have had the car looked by a professional and advised of the engine failure and this is a common issue with this make and model.
I was driving my vehicle on multiple occasions in which the car started to alarm and say, "Check charging system" at which point the car stopped all together. Also, when the cruise control is engaged, it will turn off automatically. It doesn't matter the speed the cruise control is set at, it will turn off.
ABS module/brakes system goes into limp mode randomly, which causes brake malfunction, throwing codes c1233, c1234 and c1236. There was a recall repair performed by Hyundai about two years ago, however there was two options on NHTSA recall 23V651000/campaign 251. One was to replace a safety plug fuse issue, TSB 23-01-054H . That is the recall they performed. The other recall repair which they did not perform is to replace the ABS module. The Hyundai dealer says I must pay a $225 diagnostic fee for them established they need to do this recall repair . Does that sound correct to you?

I had recall 162 - engine replacement completed in 2024 , now I have fuel leak at high pressure fuel pump, the pump that is a component of the engine has now failed which was installed during the engine replacement which can cause a major fire
While driving with my family on a busy freeway at approximately 70 mph, our vehicle suddenly displayed a loud, urgent warning: “Hybrid System Warning – Safely Stop and Do Not Drive!” At the same moment, the car lost the ability to accelerate without any prior signs of trouble. We were extremely fortunate to have enough momentum to coast to the shoulder and shut the vehicle off, unsure of how serious the issue might be. Being stranded without warning on a high‑speed highway put my entire family in a dangerous situation. After a few minutes, we restarted the car to see if we could at least get it off the freeway. The warning had disappeared, and the vehicle drove normally, allowing us to take back roads home. The lack of any prior symptoms makes this even more concerning. Losing acceleration at highway speeds with no warning is a major safety hazard. We took the vehicle to a dealership immediately, but because the warning light was no longer active, they were unable to diagnose the problem. A few days later, the same warning appeared again—this time only a couple minutes from home. I turned around immediately for safety, parked the car, and once again the warning disappeared as soon as the vehicle was shut off. At this point, we have a car sitting in our driveway that we do not feel safe driving. The dealership cannot identify or repair the issue unless the warning is active, & even then, they cannot guarantee that a diagnostic code will appear. After researching this problem online, it’s clear that many other Hyundai owners are experiencing the same issue, often spending thousands of dollars without a definitive fix. Despite how common & dangerous this problem appears to be, there are no recalls & no consistent guidance from dealerships. This situation is unacceptable from a safety standpoint. A vehicle that can suddenly lose power at highway speeds—with no warning and no reliable way to diagnose the cause—poses a serious risk to EVERYONE and needs to be investigated
The engine failed in my 2014 Hyundai Sonata for the 2nd time while driving in evening traffic on a major interstate with my elderly father in the car with me. The engine completely shut down while in mid drive on the interstate with no power. The engine and oil lamp indicators immediately came on right before the engine lost power on the interstate. This caused my safety and the safety of my father to be put at risk by not being able to have any power while in the lane of evening traffic. My vehicle was towed to the nearby Hyundai dealership, Modern Hyundai of Concord, where their service department conducted inspection of the engine issue and where it was kept for 4 months with no repairs made per the orders of Hyundai Motor America. Hyundai Motor America refused to honor their own warranty to replace the engine (engine in need of replacement for the 2nd time).
My vehicle, a 2014 Hyundai Sonata Turbo, is having brake lock-up issues. It seems to be related to the AVS (Automatic Brake System). This happens mostly when the vehicle is parked on a hill and the brakes lock up when I start moving. This has been happening for several months, but my mechanic hasn't been able to find the problem. I made an appointment with Hyundai to find out what the issue is, but they told me there's no recall related to it.

I was driving my 2014 Hyundai Sonata in a rural area when smoke suddenly entered the cabin from the engine compartment. Two bystanders waved me down, alerting me that they could see fire underneath the engine compartment. I immediately stopped the vehicle, turned it off, and exited safely. I attempted to contact 911, but reception was poor. The fire spread from the engine compartment and engulfed the vehicle, producing thick smoke that created a serious safety risk. Emergency services arrived approximately 15 minutes after being notified and extinguished the fire. The vehicle burned for approximately 30 minutes in total resulting in total loss. There were no warning lights or messages prior to the fire. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives beyond the fire report. It was towed and is being stored on private property awaiting investigation.
