Ford Fiesta transmission failure requiring warranty part replacement on Ford Fiesta

Some Ford Fiesta owners report experiencing transmission issues that may necessitate warranty part replacement, particularly concerning the Transmission Control Module (TCM). Ford has extended warranty coverage for the TCM on certain models, including the Fiesta, typically covering it for up to 10 years or 150,000 miles from the warranty start date. However, if a full transmission replacement is required, owners may face significant costs, with parts alone ranging from $4,000 to $4,250 for a 2011 model. Additionally, some owners who have surpassed the warranty limits might still qualify for a one-time TCM replacement until a specified date. It is also important for owners to be aware of the risk of "Cascading Failure," where the failure of the TCM can lead to subsequent failures of other transmission components.
