Buick LaCrosse battery dead with no crank even after jump start on Buick LaCrosse

Some Buick LaCrosse owners report experiencing issues with a dead battery and no engine crank even after a jump start. Commonly, a weak or dead 12v battery is identified as a primary cause for the engine's failure to crank or cranking slowly. Additionally, problems with the starter may be indicated if the vehicle remains unresponsive post-jump start. Many owners also note that internal degradation of the battery due to age contributes to these issues. Furthermore, a faulty alternator can lead to a dead battery situation, compounding the problem. It is recommended for owners to test the battery voltage and assess its condition to identify the source of the starting problem. If the no-crank issue persists, seeking professional assistance or visiting a service center for a thorough diagnosis is advisable to effectively resolve the situation.
