Alternator replaced multiple times

Hello, what quality of alternator are you purchasing? From the GM dealership? If not - it could be that you're getting a poor quality remanufactured alternator assembly. Too difficult to know without performing hands on testing. Other than that, though, are you sure you are properly troubleshooting the charging system which is condemning the alternator? Has the 12 volt engine battery been replaced at some point due to low charge and inability to sustain a load? It's very difficult to say what could be going on without approaching the variables present as I've shared. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
