Brake Noises That Do Not Indicate Malfunction

1. Groaning/Creeping noise at low mileage (0-300 miles):

- Noise occurs with light to medium pedal force.

- Noise occurs during medium speed stops (20-40 mph).

- Noise usually doesn't occur on the first or second stop.

- Noise occurs with warm or hot brakes (not cold).

- There may be a low frequency "judder" vibration associated with the noise.

Hyundai applies protective coatings to the brake rotors and pads to reduce corrosion during shipping and storage. These coatings may cause the groaning noise until they are worn off. Under normal driving conditions, this may take about 300 miles. If this noise occurs even after the first 300 miles, it is not necessary to attempt any repairs.

Service procedure:
None

2. Squeaking/Squealing Noise:

- Noise occurs with light to medium pedal force.

- Noise occurs during low speed stops (5-20 mph).

- Noise is more noticeable during warm, dry weather.

This noise is common on vehicles with high performance potential that are able to stop in short distances from high speeds.

Service procedure:
Follow "Service Information" section of this TSB.

3. High pitched squeaking/scraping noise:

- Noise occurs whenever brakes are applied.

- Noise may occur from just one wheel.

Hyundai uses pad wear indicators to provide an audible warning when the brake pads need replacement. Spring steel tabs that are attached to the brake pad scrape lightly on the rotor surface when the pad is worn down to the point where it should be replaced. The pad wear indicator doesn't damage the rotor surface if the pads are replaced in a reasonable time.

Service procedure:
Replace brake pads with latest available pads. Check the rotor surface for damage and machine or replace rotor as necessary.

WARRANTY INFORMATION:
Normal warranty operation codes and times apply.
