I started having problems again with the ignition switch after a long period of normal behaviour. Sometimes it would turn over and start, then sometimes not.
I recently changed the battery with a Bosch. It seemed to stop the lack of turn over, but the ignition still plays tricks by cranking engine briefly or sounding chimes with key removed even leaving automatic lights on (these can be turned off by the light switch).
I do not have easy access to any GM dealer--they are scarce in Puerto Rico and do not carry many parts. My next try is to let PepBoys change the electronic part of the ignition switch (strangely unavailable from a GM dealer but in stock at PepBoys.
The Solstice remains grounded for many many months as I try to figure this one out. Like I said I cannot depend on a far away GM dealer without parts. By the way the GM desler wanted $100 for the ignition part (they would order) which costs $28 at PepBoys. Then they want to keep the car requiring me to rent a car to get home!
You can see why I am forced to figure this thing out myself.
Disgusting since the car has only 22,000 miles.
