While driving under normal conditions, my vehicle suddenly entered a low-power (\"limp\") mode without warning. The vehicle would not accelerate beyond approximately 30\u201335 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.","products":[{"type":"Vehicle","productYear":"2014","productMake":"HYUNDAI","productModel":"SONATA","manufacturer":"Hyundai Motor America"}]}]}
