Byd Dolphin surf comfort 150hp 2026 battery drain issue
First problem. Had something strange happen and want to hear if others have seen this.
I was driving in the city (normal mode, ~50km/h average, no AC or heating on). Battery showed 17% with 16km left to my destination — should've been more than enough. But after only 14km, the car started losing power fast. It hit 6%, got noticeably weak, and then in about 2 minutes (roughly 200 meters), the remaining 6% dropped straight to 0% and the car shut off completely.
Other info that might be relevant:
On a full charge, predicted range is around 300km city driving, but in reality I only get about 240km before this happens
I charge from 20% to 100% about once a week, using a 32A single-phase 220V charger
No AC or heating used on this trip
The last 6% disappearing in 200 meters is what really bothers me. That's way too fast for actual remaining energy — feels more like the percentage shown wasn't accurate, and the battery (or one cell in it) just hit a cutoff point under load instead of gradually running out.
Anyone had a similar sudden shutdown, or noticed a big gap between predicted and real range? Wondering if this is a known issue or something to push the dealer on.oblem with my BYD.
