When buying a used Toyota Corolla, it’s best to avoid the 2009-2010, 2001-2002, and 2003-2004 models due to reported issues with the airbag system, engine problems, ignition system, and power steering. These years have had higher instances of reliability concerns. Always inspect the vehicle and check its maintenance history to ensure you’re getting a dependable car. If you’re considering something larger, the Toyota Highlander is another option to explore.
