Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. This is almost always caused by a break in the wiring coming from the sensor in the ignition lock cylinder. You would need to replace the lock cylinder by taking the steering column apart to repair it. It is very common to have a small break and it wont make connection at some points and it will at others causing it to be intermittent. I hope this helps. Please let me know if you need more help.
