Does anyone know if the original battery is under warranty on a 2016 RX350 with 22,000 Miles. I can't find information about the battery in the warranty manual and I found conflicting info on the web. Saw one post that replacement Lexus batteries are warrantied 84 months but are pro-rated on a warranty claim - not sure if this applies to the original battery. It's the weekend so can't call dealership until Monday.
