Conclusion
As previously mentioned, all Impala generations employ wheels with five lug nuts. When you reinstall the wheel, these must be securely fastened. Additionally, verifying that the lug nuts are still in place after 30 miles (48 kilometers) is critical.
Verify that they are all in place and still tightly secured. If not, tighten them once more and check again. The wheel will need to be changed if this continues.
