Toyota GR Corolla Engine Catastrophe: A Costly and Shocking Disaster.

A new GR Corolla suffered catastrophic engine failure, with a connecting rod causing a hole in the block and significant damage to the valves and casting. The cause of the problem is still unknown, but Toyota is covering over $32,000 worth of parts to replace the damaged engine components under warranty. The shop predicts that valve float may have occurred, which could point to an over-rev condition, such as an accidental downshift.
