My wife called me yesterday and said our 2016 Sienna wouldn't start. She got home from work, went into the house for about 10 minutes, then got back in the van and said when she turned the key, there was nothing but a clicking sound. The battery was dead, or too weak to start the engine. The battery is dated 2/17. The vehicle was purchased last April as a certified vehicle, and we have towing on our auto insurance, so I had the vehicle towed to a nearby Toyota dealership. I called them this morning and the vehicle is being looked at right now. I'm guessing there is a problem with the charging system, or I suppose there's a slight chance the battery could be bad, but I've never seen a battery go bad at just 3 years old. Either way, this is the first time any Toyota vehicle in our family has failed to start, and we've had quite a few over the years. I know one incident shouldn't ding my confidence in Toyota, but this is unacceptable for a vehicle this new with less than 30K miles. Luckily, my wife was at home and not out somewhere stranded.
