Mobile Mechanic - I-15 Exit 138

I-15 California Desert Lifeline

This Southern California stretch of I-15 is a high-pressure freight corridor where grade changes, desert heat, and stop-and-go traffic combine to stress brakes, tires, cooling systems, and trailer components.

• Cajon Pass is a major brake and overheating risk zone for loaded commercial trucks.
• Sudden speed changes after congestion can trigger tire failures and wheel-end heat issues.
• Dispatch priority here should lean toward brakes, tires, cooling systems, towing, and trailer stability checks.
