NHTSA Complaint #11542865 — 2023 HYUNDAI PALISADE

My wife was merging on a freeway overpass and slammed her foot into the gas peddle for a few seconds to accelerate for the merging. Her speed of travel was around 75MPH when she put her foot into it. After reaching around 82MPH she released the gas peddle for the merger. The auto's RMP shot up to around 5K and maintained the high rpm for around 5-6 sec after she released the peddle. During these few seconds the car maintained the high rate of speed and the motor was very loud. My wife pumped the gas peddle twice in rapid succession and the RPM's the wend back down and the car returned to its normal operation.
