Fiat 500 High Voltage Error

Hi, I'm getting a high-voltage system error message in my 2016 Fiat 500 Electric with 203675 km on the clock. The error is stored in the error memory, the engine sometimes shuts off, and power is significantly reduced. Could this be cable damage?

Hey, I've got a Fiat 500 too, although not sure of the year. I had something similar happen last year. Kept getting battery warnings and reduced power. Have you checked the battery's charge level? Could be an EV problem?

Thanks! I'll check the battery charge level. But could a heavily discharged battery really cause the engine to shut down completely like that? And would it show up as a generic high-voltage system error? Is electrical fault a reasonable suspicion?

Yeah, it was weird. The car basically thought it was dying. The system malfunctioned completely. I ended up taking mine to a workshop, and they said the battery was defective. Cost about 290€ to fix. Worth getting it checked, especially with those symptoms.

Thanks a lot! This is very helpful. I'll get it checked out by a professional. Sounds like a defective battery is the most likely cause, and your experience confirms it. At least I have a direction to go in!
