Tacoma start stop malfunction

Hey, I'm having a weird issue with my 2020 Toyota Tacoma with a gasoline engine. The start-stop system isn't working. It's got about 67037 km on it. Basically, the engine shuts off like it should at a light, but then sometimes it doesn't automatically restart. Plus, I'm getting an error stored and a warning light. Could it be a battery issue? Has anyone else experienced this?

A 2020 Toyota Tacoma owner experienced a malfunction with the start-stop system, where the engine would not automatically restart after shutting off at a stop. This issue was accompanied by an error message and warning light. A fellow Tacoma owner suggested that a discharged or defective battery might be the cause. Upon professional inspection, it was confirmed that the battery was indeed the problem, and replacing it resolved the issue.

Did this summary help you solve your problem?

Sounds familiar. I've got a Tacoma too. Had similar start-stop problems. Is the battery heavily discharged, or possibly defective?

Hmm, discharged battery, you say? How would I even check that myself? Is there a way to tell for sure, or am I better off just taking it somewhere?

Checking it yourself can be tricky. In my case, same symptoms pointed to a bad battery. I'd say it's best to get it checked by a workshop.

Thanks for the advice! I had it checked out and you were right. The battery was indeed the culprit, and it needed replacing. Cost me about 290€, but at least the start-stop is working again. Appreciate the help!
