Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
These lights coming on indicate a fault code is set in the air bag computer and a fault code set in the anti lock brake computer.One or more components of the air bag and anti lock brake system are at fault and caused the codes to set.The anti lock brake code can cause a loss of power when in gear all depending on what code is set.
What has to be done from here is to have the fault codes read out/checked using a fully compatible scan tool to read all computers in your model.Once this is done any codes set need diagnosed to locate and repair this issue here.Most shops or a dealer can read these codes for a fee as well as diagnose the fault.In some cases you can get a local parts store like Auto Zone to read them at no cost to you but usually cannot do the diagnosis on the codes.If you can get the codes read out and post the code info here let me know as this will help.
There are several components in the air bag and anti lock brake system that will cause codes to set so the fault codes do need read out/checked to pinpoint which component is the cause here.I have seen wheel speed sensor issues as well as anti lock brake hydraulic issues or master cylinder issues that can cause the anti lock brake light and loss of power.

Usually it is not the front brake pads or rotors at fault that would cause this here.This would be a different component at fault needing repaired or replaced for this issue.You will need to have the fault codes read out/checked with a compatible scan tool that can read all computers in your model to see what codes are set and those codes diagnosed and repaired.
