EVAP solenoid purge value in a 2007 Buick Lacrosse

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your LaCrosse. For replacing the EVAP purge solenoid on a LaCrosse, $400 might be a bit high, depending on your location and the labor rates. The part itself is relatively inexpensive, usually around $50 to $100, but labor costs can vary widely. It usually takes about half an hour of labor to replace the solenoid. Your estimate could include diagnostic time, which is another factor. I'd recommend getting a second opinion or quote from a RepairPal Certified shop to make sure you're getting a fair price. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
