On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix talk about the function of your vehicle’s catalytic converter and why they become less efficient over time.

  • 2003 Chevrolet Tahoe: The paint on my dash is starting to peel off. Is there some type of finish I can apply or do I need to have the entire dash replaced?
  • 2006 Honda Element: This vehicle is showing multiple misfire codes. What type of further damage could this cause especially relating to the catalytic converter?
  • 2007 GMC Yukon: My truck is telling me that there is an issue with the stability and traction, but it seems to be running fine. Is there cause for concern?
  • 2008 Dodge 1500: While idling, my truck is making a ticking noise. How can I find the source of this noise?
  • 2012 Nissan Pathfinder: I’m considering purchasing this car – are there any issues I should be especially concerned about with this make and model?
