Just when you thought that Toyota->ke88 was finally turning the corner after all its recall woes this year, here comes news that the manufacturer is once again issuing a (voluntary) safety recall involving approximately 1.13 million units of 2005-2008 Toyota Corolla->ke1039 and Toyota Matrix->ke1041 vehicles.

According to Toyota, the recall is being issued in the US in large part because of a potential defect in the cars’ Engine Control Modules (ECM).

According to Toyota: “On vehicles equipped with the 1ZZ-FE engine and two-wheel drive, there is a possibility that a crack may develop at certain solder points or on the electronic component used to protect circuits against excessive voltage (varistor), on the ECM’s circuit board. In most cases, if a crack occurs at certain solder points or on certain varistors, the check engine may illuminate, harsh shifting could result, or the engine may not start. In limited instances, if cracking occurs on particular solder points or varistors, the engine could stop while the vehicle is being driven.”

Steve St. Angelo, the company’s chief quality officer for North America, said that the recall is Toyota’s way of proving its commitment to its customers by doing whatever it takes to ensure that Toyota vehicles are built with paramount importance put on the cars’ safety and reliability.

Toyota is expected to send a notification to all owners sometime in September and for those willing to have their cars fixed, the automaker will replace all the ECM units at no cost. As for car owners that have had their ECM units replaced in the past, Toyota will reimburse whatever amount they paid for as long as they follow the necessary reimbursement instructions.

As part of the recall, the ECM on involved vehicles will be replaced at no charge to the owner. Beginning in mid-September 2010, Toyota will mail an interim notification to advise owners of this recall and the fact that they will receive a future notice when parts become available to complete the repairs. Owners who have previously paid for replacement of the ECM to address this specific condition should refer to the owner letter for reimbursement consideration instructions.
