Dixie toys remote control plow issues

Hello,

so the plow moves occasionally. sometimes it works flawlessly for a few seconds then nothing. sometimes it continues to move forward for a second after releasing the joystick as well. sems like a frequency issue or something.

i know there issues with the car because i already returned it once, but it is german made and assumed it would be good quality but doesnt seem to be.

sorry for the novice question. just want to know if i can fix this without buying parts or destroying it by opening it lol
