What else can cause similar battery symptoms on the 2009 Chevrolet Impala?
Mechanically related parts include alternator, starter, serpentine belt. Similar symptoms can come from those parts or from the broader system, not only from a failed battery.
Use the related-component links on this page when those combinations are published. A system-category NHTSA report is not proof that this specific part failed.
Can a bad battery cause a no-start after the battery is replaced on the 2009 Chevrolet Impala?
A failing battery can be one of several causes of a no-start after the battery is replaced. That possibility is not a diagnosis of this vehicle.
Also consider alternator and other system faults. Verify with testing rather than replacing parts from a list.
Why might a no-start after the battery is replaced continue after replacing the battery on the 2009 Chevrolet Impala?
If the symptom remains after a battery replacement, another cause — including alternator — may still be involved, or the replacement may not have addressed the actual fault.
This is a diagnostic branch, not proof that the new part is defective or that the related part has failed.
Direct mentions are NHTSA owner narratives that contain this component or an accepted alias. Related-system counts are complaints in a mapped category that do not name the part. They are never merged. Mileage statistics use odometer values from 1 to 400,000 miles. This is not a failure rate.
