| EA10006 | TOYOTA MOTOR CORPORATION | 08/18/2010 | 09/16/2010 | Engine Stall | 10V384000 | |
| 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 collected from in-use vehicles to assess whether the problems may be a continuing trend. in addition, they conducted durability testing in order to assess whether this problem was a continuing trend.toyota found that 4 of 32 collected ecms malfunctioned after thermal shock testing.toyota also confirmed that cracking could develop at solder points on the ecm circuit board that could lead to engine stall while driving and that this trend was likely to continue.the manufacturer failure data in this resume is limited to my 2005 through 2007 toyota corolla and corolla matrix vehicles.based on toyota's recall, this engineering analysis has been closed. | ||||||

| On november 30, 2009, the office of defects investigation (odi) opened a preliminary evaluation (pe09-054) to investigate alleged engine stalling, 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 causes of production defects of the engine control units (ecu) used in the my 2005 through 2007 corolla and matrix vehicles equipped with the 1zz-fe engine.failure mode a1 - bga ball failure caused by improperly cured conformal coating applied to ecu circuit boards. this can cause cracks to form in the soldered joints of some components. failure mode a2 - varistor over heating; a glass coating is created on the surface of the varistor during its production process.in case of an insufficient coating, a crack can occur in the surface of the glass coating. when ions are charged in the plating electrolytes after the glass coating process, the plating electrolytes can penetrate into the varistor through the glass crack then an electrical short occurs. with respect to these failures, if the condition arises, it can potentially lead to one or more of the following: mil on, engine stall or engine no start, harsh shifting.of the approximately 155,000 warranty and extended warranty claims toyota has analyzedthe projected 5 year failure rate of the ecu associated with an engine stall is 0.8%. this investigation has been upgraded to an engineering analysis (ea10-006) to further assess the scope, frequency and safety risks associated with the identified defects. | ||||||

| PE09054 | TOYOTA MOTOR CORPORATION | 11/30/2009 | ENGINE STALLING - ECM FAILURE | |||
| Odi has received 26 complaints alleging incidents of engine stall while driving due to ecm failure in model year (my) 2006 toyota corolla and matrix vehicles equipped with the 1zz-fe engine.the complaints allege stalls occurring randomly while driving, including some on highways and some in intersections.many allege difficulties restarting the engine or problems with recurring stalls following restart.on september 20, 2007, toyota issued technical service bulletin tc015-07, harsh shift and m.i.l. 'on' dtc p2716,providing instructions for diagnosing and repairing complaints of harsh shift with malfunction indicator lamp illumination and diagnostic trouble code p2716 stored.the bulletin calls for replacement of the ecm with an improved version (part nos. 89661-02k11, 02k21, 02k31 & 02k41).toyota's bulletin is cited in several reports.some owners also allege that they had to wait for a replacement ecm because the part was on national backorder.odi has received 5 complaints of stall while driving in my 2005 corolla and matrix vehicles and 7 complaints for the my 2007 vehicles.a preliminary evaluation has been opened to assess the frequency, scope and safety consequences of the alleged defect in the subject vehicles. | ||||||

| Intermittently my 2006 toyota matrix xr suddenly slows down to about 20 miles per hour and would not respond to pressing gas pedal. when this happens i will have to pull up to the side and turn the engine off for couple of minutes and then start. then it would be fine. it has happened on the highway and local roads. it could be dangerous if it happens right in the middle of highway. so far in the span of less than a year it has happened more than five times. we took the car to the dealer. they quoted p2103: throttle actuator control motor circuit high and will cost $1085 to fix it. i looked up the web and there were others with the same error code and replaced it but still experience the problem. after some research on the web i found that there was same symptom people experience but different error code that was covered by toyota even when the warranty expired. i was hoping my problem gets covered, too but they insist not to cover it. if this problem is a result of wear and tear, i have no problem with it. but this is clearly a defects in the vehicle that should be fixed regardless of the warranty expired or not. | |||

| My 2006 toyota matrix completely stopped running while i was driving it to work to virginia from maryland on feb. 18, 2010. i was unable to restart it and had to have it towed to my mechanic. later that day, my mechanic called to inform me that it was a computer problem with the engine control module because he had not been able to start it again after he brought inside the service bay. he informed me that there was a technical service bulletin regarding the engine control- engine no start condition and that toyota is responsible for the repair since it is still under warranty. i had to have it towed again to 355 toyota and am waiting to hear from them regarding their diagnostic testing. *tr | |||
