NHTSA Complaint #11713924 — 2024 CHEVROLET SILVERADO EV

When charging my Silverado EV at Level 3 DC Fast chargers it is not charging at the same Voltage / Power as it has been in the past at the same stations (roughly half the power). I have taken it to the service center for diagnostics but they were unable to isolate the component that caused this problem, only reproduce the problem. Further details below. What component or system failed or malfunctioned, and is it available for inspection upon request? - The Level 3 DC high voltage charging is not charging at the same voltage as a comparable Silverado EV. (Pictures attached) - I can demonstrate the problem with my car on request, I have attached pictures of a new Silverado EV charging as well. How was your safety or the safety of others put at risk? - I would not consider it safe for level 3 DC charging which involves high current and high voltage to not be working as designed. It is also unsafe to not have any warning lights indicating that the charging is not working as designed. Has the problem been reproduced or confirmed by a dealer or independent service center? Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - The problem has been reproduced and confirmed by John Heister Chevrolet of Fuquay Varina NC. They were unable to isolate a component that is causing the issue and have sent log files of the car to the engineers at Chevy to further diagnose this issue. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - There are no warning lights / messages indicating that there is a problem even now. Only the symptom of not charging at the expected Voltage / Power level. - Symptoms were first observed by me on December 16, 2026
