Vezel Start Stop Failure

The symptoms you describe for your Honda Vezel hybrid, particularly the error message coupled with start-stop failure and the warning light, strongly suggest an issue with the battery's state of charge or the battery itself. Hybrid vehicles rely heavily on a healthy battery for proper functioning of the start-stop system. Have you noticed any other electrical issues, such as slow cranking, or dimming headlights? How old is your current battery?

Thanks for the quick reply! I haven't noticed any other electrical problems, to be honest. The headlights seem fine, and the engine cranks normally when it cranks. Regarding the battery age, I believe it's the original one that came with the car. Is there any way to test the battery myself, or am I better off taking it to a professional?

Given that it's likely the original battery and you're experiencing start-stop issues, it's highly probable the battery is failing, especially with that mileage. While you could attempt a voltage test with a multimeter, the most accurate assessment requires specialized equipment to evaluate its internal resistance and overall health under load. Considering the complexity of hybrid systems and the potential for misdiagnosis, I'd strongly recommend taking your Vezel to a trusted workshop for a proper diagnostic check. They can pinpoint the issue and confirm whether the battery is indeed the culprit before you spend money on a replacement.

Thanks a million for the advice! I was dreading it, but it sounds like a trip to the shop is unavoidable. I took your advice and brought it in. Turns out, the battery was indeed heavily discharged and defective, just like you suspected. They replaced it, and the start-stop system is working perfectly again. Total cost was around 290€, which I guess isn't too bad. Really appreciate your help!
