   I was driving down the road and came to a stop at a stop light. After accelerating again my car lost the ability to increase speed above 20 miles/hour and would not shift gears. I was heading to the turn lane to get on the interstate and quickly had to change lanes to find an area to pull over as I could not reach highway speeds. I turned the car off.

    Both horns on my 2023 Hyundai Santa FE have failed 3 times. The first set was covered under warranty (3/24), the second set cost $499.64 (3/25).
