What can fail
Brake rotor bolts on the front and rear wheels can break due to hydrogen embrittlement. A crack may form under the bolt head, causing it to separate and lose its clamping force. This weakens the bolt and can affect braking performance.
What the fix does
Dealers will replace all rotor bolts with new ones.
