Toyota Recalls a Million Corolla and Matrix Models

Add another million or so to the growing Toyota defect list.

by on Aug.26, 2010

More than a million Corollas in the U.S. and an unknown amount globally are recalled.

Toyota Motor Sales (TMS), U.S.A., Inc., today announced that it will conduct a voluntary safety recall involving approximately 1.13 million 2005-2008 Model Year Toyota Corolla and Corolla Matrix vehicles sold in North America.

Defective engine control modules are the latest safety defect at the beleaguered Japanese company.

On vehicles equipped with the 1ZZ-FE engine and two-wheel drive, a crack may develop at solder points or on the electronic component used to protect circuits against excessive voltage (varistor) on the ECM’s circuit board.

In most but not all cases, Toyota says if a crack occurs the check engine may illuminate, harsh shifting could result, or the engine may not start. In some instances, if cracking occurs on particular solder points or varistors, the engine could stop while the vehicle is being driven.


There are three unconfirmed accidents alleged to be related to this defect, one of which reported a minor injury.

As part of the recall, the ECM on involved vehicles will be replaced at no charge to the owner as is required by U.S. regulations.


Another Major Safety Investigation Targets Toyota

Best-seller Corolla, Matrix face new troubles over stalling.

A new NHTSA investigation targets potentially faulty circuit boards that could cause engine stalling with the 2005 - 07 Corolla and Matrix.

Toyota is facing yet another major investigation, involving what has been one of the company’s best-selling vehicles.

The National Highway Transportation Safety Administration has launched a new investigation into possible defects with the maker’s Corolla and Matrix models, sold between 2005 and 2007, which reportedly face problems with unexpected engine stalling.

In The News...In The Know.

If the NHTSA investigation validates claims of a safety defect, Toyota could be pushed to order a recall of 1.2 million vehicles.  The situation compounds the Japanese automaker’s already severe safety-related problems, more than 8 million of its vehicles being recalled since last October due to two separate sudden acceleration-related defects.  Over a million more products, from the Toyota Tundra pickup to the Lexus HS250h hybrid, have been called back for reports covering everything from severe corrosion to leak fuel tanks.

Problems involving Corolla come at a particularly bad time considering both the increased competition in the compact car segment – and investigations into other problems with the popular Japanese product.


Corolla May Be Next on Toyota Recall List

Maker preparing fix for unexpected stalling problem.

by on Mar.18, 2010

This 2006 Corolla sedan could be the next model on Toyota's recall list, here for stalling issues.

Toyota’s nascent attempt to overcome image problems regarding the safety of its vehicles could be in for another setback, with the automaker telling U.S. regulators it is considering ways to prevent the unexpected stalling in the world’s most popular nameplate.

In a letter to the National Highway Safety Administration, the embattled automaker insisted the problem does not pose “an unreasonable risk,” but is nonetheless looking at ways to prevent stalling, which it has traced to engine control modules provided by two of its suppliers.

Critics of course have said that Toyota – and all automakers – do not properly test software, and that the safeguards used by other industries are not in place. Worse, NHTSA has only one software engineer on staff, and its regulations were developed before the onset of the widespread use of electronics in vehicles, including drive by wire systems that are now ubiquitous.

Your News Source!

NHTSA reports it has so far received 76 complaints involving 2005 through 2007 versions of the Corolla and Matrix models involving stalls that have occurred unexpectedly, sometimes at high speeds.

The problem is, ironically, believed to be related to a fix for a previous problem with those two vehicles.
