What to do right now
- Do not continue driving if lights or steering assist weaken

What to tell the dispatcher
- Symptoms before failure

What can change the price

Ask for an itemized estimate, included mileage, accepted payment methods, and any condition that could change the quote. The listed provider sets the price and arrival time.
