Battery failure after 6600 km – zero support from NIU
I used to be a loyal NIU customer for over three years. My MQi GT 40 was well maintained and the batteries were always stored correctly. Then, after just 6600 km, one of the two batteries suddenly failed – no deep discharge, no misuse. I sent the battery to NIU's official battery service in Frankfurt, and it was returned as “irreparable.” I contacted NIU directly – multiple times, with all details: VIN, battery serial number, usage history, photos. Each time, I received automated responses from generic names like “Kristy,” “Emma,” “Rachel”, and no one actually reviewed my case. They just kept pointing me back to the dealer. But here’s the problem: my dealer is no longer a NIU partner, so NIU was my only option – and they refused to help in any way. I didn’t even ask for a free battery – just a fair offer, like a discounted replacement. Others received that – I didn’t. If an EV battery fails just after warranty, and the company hides behind automated replies, what does that say about the brand? Sadly, I’ve lost all confidence in NIU and can’t recommend them anymore.
