- Pulsation or vibration in the steering wheel or pedal
- Burning smell around the tires
- Brake dashboard light illuminated
- A feeling that something is "off" with the braking system
Transmission & Drivetrain Service
Service Importance
The transmission, differentials, and transfer case (xDrive) are among the most neglected service areas on a car. Over time, these fluids break down and become contaminated, which can cause increased wear and potentially lead to costly failures.

- Serpentine belt, tensioner assembly, and all idler pulleys: Replaced
The next service for these components was scheduled for 220,000 km (approx. 137,000 miles) .
Battery Service
Car batteries generally last between three and five years . You may need a replacement sooner depending on the climate in your area as well as your driving habits.
