Check engine light on took it to the dealer who told me that it the charcoal device in the emission control system needed replacing, over $600. I ask if it was covered under the ZERO emissions warranty. They told me that it wasn't. Not very trusting of car dealers I called Toyota customer service. They told me that it was covered. Had I not call Toyota the dealer could have charged me and then turned in a warranty reimbursement. For god's sake this is a Toyota dealer you'd think they'd know what'c covered, yes? There's a lot more than I have room here to write.
