Mustang MachE weak battery
Summary of the thread
A 2020 Ford Mustang Mach-E is experiencing a weak battery and flickering lights, potentially due to a defective battery sensor, as indicated by erratic voltage readings. Another owner with similar issues found that a faulty sensor was affecting the battery management system. The suggested solution is to have the vehicle professionally assessed to confirm the sensor's condition and address the electrical problems.

Can you elaborate on the electrical issues you experienced and how you resolved them? Did you also suspect a faulty battery sensor during troubleshooting?

Absolutely! Okay, so picture this: My Mach-E acted like it was possessed. One minute, full power; the next, it was struggling to keep the lights on. I even had the infotainment system glitching out. I didn't dive too deep myself; I took it straight to the shop because electricity is like magic to me - cool, but scary. They said it was a bad sensor messing with the battery management system. Long story short, get it checked out by a pro!

I appreciate you sharing your experience. I'll schedule a consultation with a technician for a thorough assessment. I think the repair might be around 315€ if the battery sensor is the problem. Thanks again!

Whoa, sounds familiar! I've got a Mustang Mach-E too, and I had some spooky electrical gremlins a while back. Weak starts, lights dimming... it was like driving a haunted house. I wouldn't rule out the sensor, especially if you're seeing weird voltage. It's like a tiny brain trying to tell you something important, but it's speaking gibberish.
