Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Did all of these start at the same time?
Thank you. Start by checking the connections at the battery and checking the battery itself. A lack of voltage will cause this. If the battery and connections are fine then the body control module or the ignition switch may be failing. There is also a common issue with a connector under the carpet behind the driver seat. This connector becomes damaged due to its location and will cause this. I hope this helps. Let me know if you need more help.
