On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix talk about the common factors that contribute to some auto repairs or services taking a bad turn. Also on this show:

• How miscommunication can occur between you and your auto repair shop.
• Why you shouldn’t expect accurate pricing for parts or a repair over the telephone.

• When it’s important to get a second opinion and ways you will benefit by having a “home” shop.
• Tips to help ensure a safe trip if you’re traveling to see the snow.
• What advice can you give me about tire inflation levels in Arizona?
• 2015 GMC 2500: My truck is telling me to consistently add diesel exhaust fluid. Now my check engine light is also coming on. Could this be a software issue?
• 1994 Ford Explorer: My truck is overheating while idling. I’ve tried many of the common fixes – what other parts or services should I consider?
• 2004 Pontiac Aztek: There is a light telling me that my hatch is consistently open, however the dome light stays off. How can I fix this?
• 2015 Nissan Rogue: The fan on my AC jumps up each time I plug something into my USB port. Have you seen this problem before?
