Stalling Issue on Toyota Vehicles Leads to another Recall
Tuesday, August 31st, 2010Once again Toyota vehicle owners were dealt bad news. On August 26, 2010, Toyota announced a recall of more than 1.1 million 2005 through 2008 model Corolla sedans and Matrix hatchbacks over faulty engine-control computers that could cause the vehicles to stall in traffic, according to a recent USA Today news report.
The huge recall Toyota’s 15th in 2010 came just two days after the National Highway Traffic Safety Administration announced it was ratcheting up its investigation of the stalling problem. NHTSA said it has received 163 complaints. Toyota blamed the faulty computer, called an electronic control module or ECM for the stalling and said it will replace them in the recalled vehicles. The company said it has three unconfirmed reports of crashes, including one involving an injury.
Owners will be informed of the recall by mail in September and then will get a second letter when dealers have the parts for the repair.
Of all of the 5.8 million cars that Toyota has recalled since January 1, this is the first that involves a problem with the engine computer. Toyota continues to defend the ECM against allegations that it might be at fault in some sudden-acceleration incidents, which have already prompted two huge Toyota recalls for mats that can jam the gas pedal and pedals that can stick open.
Some auto-safety advocates say it raises new doubts about the ECMs.
“If you can get it wrong on stalling, you can get it wrong on unintended acceleration,” says Clarence Ditlow, executive director of the Center for Auto Safety in Washington, D.C.
And Sean Kane of Safety Research & Strategies said the stalling problem is similar to runaway car problems in that the computers don’t always create diagnostic trouble codes that let mechanics or investigators figure out what went wrong. “The heart of the problem is really their inability to detect the problem.”
Toyota has known about the stalling problem for years. It issued four technical service bulletins, the most recent in 2007, telling mechanics about the problem and instructing them to replace the module. But it did not deem the problem to be a safety risk needing a recall.
It was only after extreme temperature tests in which four of 32 units malfunctioned that Toyota decided to voluntarily proceed with the recall, Hanson said. It was found stalling could be due to faulty coating on the module’s circuit boards or a crack in the surface of a glass coating.
