• 2010 Chrysler 300: I’ve noticed a “jolt” in my vehicle at stoplights. How can I begin diagnosing this issue?
• 2003 Ford Expedition: There’s a small crack in my gas tank. Is there somewhere I could track down a replacement? Is this repairable?
• 2013 Dodge Ram: The automatic lock system on my truck has worn out, and I was quoted over $1,300 to have it fixed. Any advice?
• 2012 Volkswagen Tiguan: What information can you give me about my vehicles timing chain system and replacement interval?
