What is cost to get an estimate on a 2007 Cadillac STS for a problem where it will not turn off properly so it drains the battery? It is not the alternator or battery that has been determined already. Trying to determine if the car is worth keeping.

I would bring it in for an accurate estimate

Sounds like an ignition switch issue. Did you buy thr car from them? Make your appt And bring a couple hundred with you.

The only way to get an ACCURATE ESTIMATE is to bring it in. I would recommend calling for an Appointment so you don't waste your time waiting.

I agree. Call first. Talk to "service department". ASK QUESTIONS OBER PHONE NUT UOU PROBABLY WILL NEED TO MAKE AN APPOINTMENT.
