Tiburon start stop malfunction

My 2003 Hyundai Tiburon, gasoline engine, with 176118 km is having start-stop issues. The error memory has a fault, the engine cuts out unexpectedly, and the warning light comes on. I can't figure out what's causing it.

A 2003 Hyundai Tiburon is experiencing start-stop issues, with the engine cutting out unexpectedly and a warning light activating. The problem is suspected to be related to a defective battery, as these systems are sensitive to voltage drops. After taking the car to a workshop, it was confirmed that the battery was indeed the cause of the issue, and it was replaced.

Did this summary help you solve your problem?

That sounds frustrating. Does it happen more when the car has been sitting, or only when the engine is warm? Maybe a battery issue, have you checked the voltage?

Thanks. It happens regardless of engine temperature or how long it's been sitting. Could a bad battery cause these symptoms?

Yes, a discharged or defective battery is the most likely cause; these systems are very sensitive to voltage drops. It's probably more than you can diagnose yourself, I'd suggest a workshop.

Thanks for the confirmation and advice. I took it to a workshop, and the battery was indeed defective. The total repair was 290€.
