Problem overview

Some Toyota Matrix owners report experiencing issues related to the Engine Control Module (ECM) due to a safety recall (A0J) affecting certain 2005 through 2008 models. These owners have noted that a manufacturing defect in the ECM can lead to cracks at solder points or varistors on the circuit board, resulting in the illumination of the Check Engine Light and harsh transmission shifting. Toyota dealerships are conducting inspections and will replace the ECM at no cost to owners as part of the recall, which is being carried out in two phases, with preparations expected to be completed by November. It is crucial for affected vehicle owners to have the ECM inspected and replaced to ensure their vehicle's safety and proper functioning.
