How do I cancel Mechanical Breakdown Protection (MBP)? Contact an Alliant Credit Union Member Service Representative at 800-328-1935 If you trade in your vehicle that is protected by MBP, or determine that you no longer wish to protect your vehicle, the remaining coverage may be canceled or transferred. Refunds will be applied towards your loan balance if the cost of MBP was borrowed as part of a loan. Please refer to your service contract for details
