my Acura MDX YF3 (2022-Present) has a strong vibration at high speeds

Symptoms

• Strong vibration felt in the steering wheel and/or seat at speeds typically above 50 mph.
• Possible accompanying noises such as humming or grinding.
• Uneven tire wear or visible damage to tires.
• Steering wheel may feel unsteady or wander.

Diagnostic Steps

1. Visual Inspection of Tires:

   • Check for uneven wear patterns, bulges, or damage on all tires.
   • Ensure tires are inflated to the recommended pressure.

2. Wheel Balancing Check:

   • Take the vehicle to a tire shop and have the wheels balanced. An imbalance may cause vibrations.

3. Alignment Inspection:

   • Inspect the wheel alignment using an alignment machine to ensure that the wheels are aligned correctly.

4. Suspension Component Inspection:

   • Examine suspension components (tie rods, control arms, bushings) for wear or damage.

5. Drivetrain Inspection:

   • Check driveshaft and CV joints for any signs of wear or damage.
   • Ensure that the engine and transmission mounts are secure and not broken.

6. Scan for Error Codes (if applicable):

   • Use an OBD-II scanner to check for any stored fault codes related to the drivetrain or stability control systems.
