type: Action
additional type: https://schema.org/LegalForceStatus
description: On August 26, 2010, Toyota submitted a Defect Information Report to the National Highway Traffic Safety Administration (NHTSA) regarding problems with Engine Control Modules that could result in engine stall while driving in certain model year (MY) 2005 through 2008 Toyota Corolla, Corolla Matrix and Pontiac Vibe vehicles equipped with the 1ZZ-FE engine and two-wheel drive and manufactured between April 19, 2004 and January 2, 2008.Toyota's report indicated that cracks may develop at certain solder point or on varistors on the ECMs.According to Toyota, such cracks generally resulted in engine warning lamp illumination, harsh shifting or engine no-start.In some cases, if the cracking occurs on particular solder points or varistors, the engine could stop while the vehicle is being driven.Toyota will notify owners of subject vehicles that they should return their vehicles to a Toyota or Pontiac dealer.Dealers will be instructed to inspect the production number of the ECM for each vehicle and replace the ECM if necessary.On November 30, 2009, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE09-054) to investigate alleged engine stall while driving in model year (MY) 2006 Toyota Corolla and Corolla Matrix vehicles.In its response to ODI's information request, submitted on March 2, 2010, Toyota indicated that it had identified two possible conditions with ECMs used in MY 2005 through 2007 Toyota Corolla and Matrix vehicles:1) cracks forming between the IC and the board caused by an improperly cured conformal coating applied to the circuit boards after the soldering process is completed; and 2) cracks occurring in a variable resistor (varistor) due to overheating.During the manufacturing process a glass coating is created on the surface of the varistor.Between March and August 2010, Toyota began collecting ECMs from the field to further investigate failure modes that may result in engine stall.Toyota also conducted durability testing on ECMs col
