It’s defective people, not switches!
A friend of mine that had a tune up and dyno shop over 30 years ago was constantly having the problem when switches on the column came out.
The problem was people having a whole lot of keys on the ring/chain dangling below the ignition which was messing up the switches.
That was all makes nor just GM.
Congress can go stick their investigation up their ass!!!
“The problem was people having a whole lot of keys on the ring/chain dangling below the ignition which was messing up the switches.”
Obviously, this is a bad policy and a safety hazard for the driver EVEN WITH switches that work perfectly.
What I find highly disturbing about what happened, is that GM changed the part without changing the part number. In the manufacturing environments I’ve worked in, that behavior would get you fired very quickly, up to the managers who permitted/ignored it.
The reason is, manufacturing must have traceability for liability and safety agency reasons. Suppose that you have a recall of an electrical, UL-approved product for a safety reason. What would you rather do - recall and eat the expense of units between serial number 000234 and 003456, or every single product of that type you ever made, up to serial number 856,456?
...and they DIDN’T have a whole lot of keys dangling on a keychain when the switch was on the dashboard? Color me skeptical of that as a root cause.
