Electric range is dropping after full charge?

[Year 2000]

I picked up a Corsair plug-in hybrid back sometime in July last year. At first, the car's dashboard would show about 35 miles of electric range after a full 100% charge. But now? After charging all night, it only shows like 15 miles, sometimes even less... like 14 max when driving. I asked the dealer, and they said shrugged it off as normal. Anyone else notice their electric range dropping like this over time? Should she be worried or nah?

It is pretty common for plug in hybrids to show some drop in electric range over time as the battery ages. But going from 35 to 14 miles sounds a bit steep it might be worth getting a battery health check just to be safe. others have had similar issues and the dealer support varies. Keep an eye on it

Some loss is normal, in colder temps or if your driving habits changed (more highway, AC/heat use, etc.), but cutting down to 14;15 miles from 35 is sus, I'd ask the dealer to run a battery health check if they haven't already

A battery droppin by half on a relatively new car? That's sus as hell. What about the consumption average? How's it looking?
