BMW i5 Brake Light Warning Puzzle Needs Expert Help

Hey there! I had a similar issue with my 2021 BMW iX3. The brake light warning kept popping up on my dash. Initially thought it was just a blown bulb, but turned out to be more complex. Took it to the garage last month where they diagnosed a faulty brake light switch, just as you suspect. The switch wasn't sending proper signals to the car's computer. They had to replace the entire brake light switch assembly and recalibrate the system. It was a serious electrical issue that could've affected the brake lights' functionality, definitely not something to ignore. The repair wasn't just about swapping parts; they needed specific diagnostic tools to properly reset the system. I'd suggest finding a garage that specializes in BMW EVs. The electrical systems in these cars are quite sophisticated and need proper expertise. Best of luck with the repair!

Hey! Thanks so much for sharing your experience! Really glad to hear I'm not the only one who's faced this. Sounds like we had pretty much the exact same issue. Just curious, do you remember roughly how much you ended up paying for the whole repair? Also, has everything been working smoothly since they fixed it, or have you noticed any other quirks?

Great news, I had a totally different outcome than expected! After taking it to the mechanic, turns out I'd just hit the parking brake switch by accident when adjusting my seat. Caused the whole warning system to go haywire. The mechanic just reset the system and showed me exactly what happened, didn't cost me a penny since it was just a mechanical error! Since then (about 3 weeks now), everything's been running perfectly smooth. No more warning lights or error messages. Honestly feeling a bit silly about it now, but these high-tech EVs can be super sensitive sometimes. Just wanted to share this update in case you're experiencing something similar. Might be worth checking the simple stuff first before assuming it's a major repair. These BMW systems can be pretty dramatic over minor things! Let me know how you get on with yours!

Hey! Thanks for sharing that follow-up! Boy, do I feel silly now... You won't believe it, but I just got back from the mechanic and guess what? My issue was something ridiculously simple too. Turns out there was just some dirt buildup around the brake light sensor connections. The mechanic cleaned it up, ran a quick system reset, and everything's working perfectly now. Only cost me for half an hour of labor, way better than the expensive repair I was dreading! These modern EVs really can be dramatic with their warning systems, hey? Mine was acting like it had a major malfunction when it just needed a bit of cleaning. Definitely learned my lesson about checking the basic stuff first. Really appreciate you sharing your experience, helped me feel less anxious about the whole situation. Car's running great now, and I've found a much better mechanic in the process.
