why does my Acura MDX YF3 (2022-Present) smell like burning rubber

Symptoms

• Burning rubber smell inside or outside the vehicle
• Possible accompanying sounds of friction or grinding
• Engine overheating warning light (if applicable)
• Smoke visible from under the hood or near the tires
• Increased engine temperature gauge reading

Diagnostic Steps

1. Visual Inspection:

   • Open the hood and inspect for any visible signs of wear or damage on belts, hoses, and wiring.
   • Check for any leaking fluids that may be making contact with hot engine components.

2. Check Engine Codes:

   • Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) that may indicate engine or transmission issues.

3. Inspect Drive Belts:

   • Check the serpentine and accessory drive belts for cracks, fraying, or misalignment.

4. Examine Tires and Wheel Wells:

   • Inspect the tires for signs of excessive wear or damage that could cause a burning smell, such as a stuck caliper.
   • Look for any debris lodged in the wheel wells.

5. Check for Electrical Issues:

   • Inspect the wiring harness and connectors for signs of melting or short-circuiting.

Repair Instructions

1. If the problem is due to a damaged drive belt:

   • Tools Required: Socket set, torque wrench, belt tensioner tool.
   • Estimated Time: 1-2 hours.
   • Steps:
     1. Disconnect the negative battery terminal for safety.
     2. Remove any necessary engine covers for access.
     3. Use a belt tensioner tool to relieve tension on the belt.
