Problem overview

Some Ford Thunderbird owners report experiencing unintended acceleration issues linked to problems with the throttle control and brake failure. These concerns can stem from a dirty throttle body, which may cause slow acceleration, poor engine performance, and erratic idle. Additionally, some owners have reported sudden unintended acceleration while braking, potentially due to malfunctions in the electronic system controlling the vehicle's powertrain. The introduction of throttle control mechanisms in modern vehicles has also been associated with increased cases of unintended acceleration. Furthermore, the Ford Motor Company has faced a significant class action lawsuit regarding allegations that electronic throttle control issues could lead to uncontrollable acceleration. Given the complex and sporadic nature of these safety concerns, it is crucial for owners to address throttle control and brake failure issues to ensure vehicle safety and optimal performance.
