Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Matt Allen of Virginia Auto Service in Phoenix, AZ talks about how automotive services, repairs, maintenance and components have evolved over time. Also on this show:

• What the different colors of warning lights can tell you about the health of your vehicle.
• Information about a few of the less common dashboard warning lights.
• Are there warning lights that you can ignore? Which should you not?
• 2008 Toyota Tundra: My truck struggles to start and I've been quoted two different repairs from two separate dealers. What do you think could be causing this?
• Ford Windstar: The ABS light comes on intermittently in my van - especially during colder temperatures. How concerned should I be with the health of my brakes?
• 2004 Ford F150: I was quoted up to $800 to replace the spark plugs in my truck. Does this seem reasonable?
• 2005 Porsche Cayenne: Where would you recommend I take my vehicle for cosmetic repairs and should I always be using premium gasoline?
• 2016 Chevrolet Tahoe: I've noticed a loud thump coming from the rear of my vehicle while driving over speed bumps. What could be causing this?
