On 10/02/14 the orignal battery in the truck failed. It was replaced with an interstate battery,#mtp24. This battery failed and was again replaced with another interstate battery on 10/8/15 at no charge. This battery failed and was replaced again today, 4/18/16. Greg leblanc Toyota @ 220 s. Hollywood rd. , houma, la 70360 tested the vechicle and found nothing to be drawing the battery down. They found nothing wrong with the battery but when when we tried to start it(parked in the driveway at our home) after using it on Friday night, it would not turn over in any fashion the next day. My question is there something else that could be wrong with the vechicle that may show in the testing that it is working but could be faulty. I doesn't make sense to go through 3 batteries in 18 months. I checked to see if there were an recalls on the interstate batteries but didn't find anything from 2006 to present.
