GM doesn't back their products.
Your ABS can at least be repaired if the pump is running all of the time. GM wants $700+ to replace these defective ABS modules.
They can be permanently and properly repaired for a flat rate of $100.00. You will get your ABS back to perfect working order with what should be a permanent repair.
