WASHINGTON — U.S. safety regulators have stepped up their investigation into complaints of stalled engines on Toyota Corolla sedans and Matrix hatchbacks, but government officials stopped short of announcing a recall.
The National Highway Traffic Safety Administration upgraded its investigation last week and is looking at two possible causes behind the stalling: improper coating on circuit boards and a crack in the surface of a glass coating. Both could have happened during production of the cars.
The new probe, called an engineering analysis, covers 1.8 million Corolla and Matrix cars from model years 2005 to 2007.
