My 2010 lacrosse won’t crank with new starter

Hi, this is Dusty; I'm one of the auto experts on RepairPal's Car Genius team! If your 2010 Buick LaCrosse won't crank even after replacing the starter, there are a few things to check. First, ensure the new starter is installed correctly and all connections are tight. Sometimes, a faulty connection or improper installation can mimic a bad starter. Second, check the battery voltage to ensure it's sufficiently charged (at least 12.6 volts). A weak battery can prevent the starter motor from turning over. Third, inspect the ignition switch and starter relay for proper operation. Issues with these components can also prevent the starter from engaging. Lastly, if smoke came from the exhaust before it stopped running, it could indicate a more severe issue, possibly a mechanical issue in the engine.
