The vehicle went into limp mode and died on the side of the road. AAA installed a new battery, which temporarily restored operation, though the \u201cService Charging System\u201d warning remained. I drove it home, let it sit for several days, and then took it to a Chevrolet dealership.  Although the warning light had cleared, I brought it in out of caution. The first dealer diagnosed a failed alternator and recommended replacement at a cost of $2,158.75. I was also told the vehicle was not included in any active recalls related to this issue.  Believing the price was high and wanting a second opinion, I went to another Chevrolet dealer. They ran the same diagnostic and found no issue with the alternator or generator, charging only a diagnostic fee. They also said if the alternator had needed replacement, the cost would have been around $1,300.  I mentioned to both dealers that I had seen similar alternator/charging system failures recalled on other 2020 Silverado models. Online forums and customer complaints suggest that many Silverado 1500 trucks with the 3.0L Duramax are experiencing similar problems, indicating a potentially broader issue.  Given the inconsistency in diagnostics, the significant cost discrepancy, and the number of similar consumer reports, I believe this issue may be more widespread than current recalls reflect. I respectfully request that NHTSA investigate whether the existing recall should be expanded or if a new recall should be issued for 2020 Silverado 1500 models equipped with the 3.0L Duramax.  This issue occurred shortly after a separate failure related to the NOx sensor, which I am submitting under a separate complaint.","products":[{"type":"Vehicle","productYear":"2020","productMake":"CHEVROLET","productModel":"SILVERADO 1500","manufacturer":"General Motors, LLC"}]}]}
