• What to do if you happen to fail your emissions test.
• 2002 Honda Accord: While driving over bumps, I’m noticing a noise that sounds like glass moving. After taking it to the dealer the problem is still worsening. Should I take this to a regular shop or a body shop?
• 2014 BMW: My tire pressure light is on. We’ve discovered a nail in the tire, but is there a special process since these tires are run-flat?
• 2009 GMC Sierra: Why is it that Diesel fuel automobiles take emissions every year? Why am I being asked to floor the engine during a test?
• 2007 Kia Rio: The CD in my car radio works fine- but won’t eject. How do I get this out?
• 2010 Dodge Caravan: My engine light came on recently but I solved the problem. Am I okay to take this to emissions or do I need to wait since I’ve disconnected my battery?
