NHTSA complaint #11081778, filed 2018-03, 14,000 miles

“I was trying to merge onto a freeway from a complete stop and because this freeway has an extremely short on-ramp, you need to get up to a high speed in very little time. As such, I put my car in Sport driving mode and accelerated very hard from a complete stop. The car accelerated as normal for a few seconds (I reached approximately 40 to 50 MPH), then I felt the car lag and felt a loss of power. The car was in limp mode and I couldn’t accelerate even though I was pressing the gas pedal all the way to the floor. …”
