Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the high-voltage battery before working on electrical systems.
•Allow brakes to cool before handling; they may be extremely hot after use.

Symptoms

•Burnt rubber smell inside or around the vehicle
•Check engine light illuminated
•Reduced braking efficiency
•Visible smoke or residue on tires or brakes
•Unusual noises during acceleration or braking

Diagnostic Steps

1
Inspect the tires for uneven wear, damage, or objects lodged in the tread.
2
Check the brake components for overheating signs, such as discoloration or a burning smell.
3
Scan the vehicle's onboard diagnostics (OBD) for any error codes that may indicate electrical system issues.
4
Inspect under the hood for any signs of melted insulation on electrical wiring or components.
5
Test drive the vehicle to replicate the smell and determine when it occurs (e.g., during braking, acceleration, or idling).

Solution
