Recall Division, I am writing to bring to your attention a safety and performance issue related to a potential defect in the EVAP canister purge valve of my 2017 ford focus, which may be linked to the previously issued recall for this component. The EVAP canister purge valve in my vehicle has become stuck in the open position, resulting in the engine burning an excessive amount of fuel. This has led to an overly rich fuel mixture, which has placed significant strain on the vehicle's catalytic converter. As a result, the converter is showing signs of damage, including clogging, rough idle, and potential stalling Given the severity of this issue, I am requesting that the federal safety agency investigate the potential consequences of this defect and determine if the damage to the catalytic converter—stemming from the malfunctioning purge valve—should be addressed through an expanded recall. The defect appears to not only affect engine performance but could also present long-term risks to vehicle safety, including the possibility of unexpected stalling while driving. I respectfully ask for guidance on the appropriate steps to take in order to address this matter, including whether additional recalls or safety measures will be initiated to cover the catalytic converter damage caused by the faulty EVAP canister purge valve. Additionally, I would appreciate any further instructions on how to proceed with obtaining repairs or replacements for the defective parts. Thank you for your attention to this matter. I look forward to your response and assistance in ensuring the safety and performance of affected vehicles.
