Karna had taken admission to learn weaponry with Guru Parashurama. Karna had not disclosed that he was a warrior. Parashurama once understands that Karna was a warrior and becomes angry and curses Karna that he would forget the mantras he taught and his chariot gets stuck in battle ground, when he needed them most during a battle. Hence Karna's chariot gets stuck during the battle when needed it desperately.

Karna.
In the Hindu epic Mahabharata, Karna Kavach and Kundal were given to Karna by his father, Surya. Karna wore them in battle. However, during the Kurukshetra war, Indra, disguised as a Brahmin, asked for them as a boon before going into battle with Karna's son, Arjuna. Reluctantly, Karna gave them away, which ultimately led to his downfall in the war.
The father of Karna, the warrior from the Indian epic Mahabharata, is Surya, the sun god. Karna was born to Kunti and was adopted and raised by a charioteer.
Karna was cursed by his guru, Parashurama, who was unaware of Karna's true identity as the son of a Kshatriya. Parashurama believed Karna to be a Brahmin, and when he discovered the truth, he cursed Karna that in a moment of need, his chariot wheels would get stuck in the ground. This curse played a significant role during the Kurukshetra War, ultimately leading to Karna's downfall.
