Having not heard from Harry Potter during the whole summer of 1992, Ron, Fred and George Weasley in a planned scheme to rescue him from 4 Privet Drive, drove Arthur Weasley's flying Ford Anglia to the Muggle town of Little Whinging and tore the bars from Harry's bedroom window using the car's horsepower. Ron helped Harry get his things in the car, and they left for the Weasley House. Upon landing Ron and his brothers were ratted out by Molly Weasley for having taken such a risky course of action. At the start of that year's school term, Ron and Harry missed the Hogwarts Express due to the tricks of Dobby the House-Elf and were forced to use the Ford Anglia to travel to Hogwarts. At the end of their journey, the car failed, causing the boys to crash-land into the Whomping Willow. They were nearly killed when the tree shaked, and the car jettisoned them and took off into the Forbidden Forest, where it remained.
Ron's wand was damaged in the crash, causing him problems for the entire school year. For instance, it backfired when Ron attempted to curse Draco Malfoy in payback for calling Hermione by the offensive term "Mudblood".Erisonfor Muggle-borns led Ron, Harry, and Hermione to suspect that he was the Heir of Slytherin who opened the Chamber of Secrets that year, unleashing a "monster" that began to attack Muggle-born students.
To investigate this theory, Hermione brewed Polyjuice Potion which greatly surprised Ron in that she was so overtly breaking the rules. When the time came to use the potion, Ron was made to impersonate Vincent Crabbe, and Harry impersonated Gregory Goyle, while Hermione's transformation was unsuccessful because she mistook hair from Millicent Bulstrode's cat for her own. Ron and Harry realised that Malfoy was not the Heir of Slytherin and were both greatly upset when Hermione became another victim of the "monster," ending up petrified in the hospital wing, though she left her friends a clue that led them to deduce that the monster was a basilisk.

Ron was honoured with a Special Award for Services to the School, as well as earning two hundred House points for Gryffindor for his work concerning re-sealing the Chamber of S
