Brian Eddie Garcia Posted July 19, 2019 Share Posted July 19, 2019 Hopefully I reach some Toyota Techs or experts here... It's been over a year now my wife's Venza XLE V6 had it's car battery dying now and then. And that's with a fresh battery from Toyota. My wife read several threads on possibilities but we still don't know what's up. It seemed to happen after the headlights were on (auto mode). It happened other times during the day as well. We turn the motor off by pushing the start button and we would here the bell chiming, which is not normal. Normally you just see the doors open symbol and there's no sounds when you leave the car. She took the car to the dealer who of course told her the battery tested bad. They gave her a new Toyota battery which didn't last long before the same things were happening. She'd have a dead battery often. I went ahead and bought a new battery last week and I ran a voltage check and alternator check. I found no significant drain on the battery and the alternator was putting out 13.8 volts. Today I drove her car and I got the chiming again when i was exiting the car. I've read forums with problems like the motorized hatch isn't closing all the way, the brake lights switch is bad, the FOB is low, etc. Near as I can tell it's not those things. I need help from anyone who has seen this kind of issue. I will check again for a Parasitic leak at the positive terminal. THANKS Quote Link to comment Share on other sites More sharing options...
retvethogrider Posted July 20, 2019 Share Posted July 20, 2019 We have a 2014 Venza Limited. Now on our third battery in less than 40,000 miles. Car is garaged every night. Quote Link to comment Share on other sites More sharing options...
Brian Eddie Garcia Posted July 22, 2019 Author Share Posted July 22, 2019 Wow. This is our 3rd in 4 years. There must be a parasitic drain that’s intermittent. I’m hoping to find a Toyota tech that knows what it might be. Quote Link to comment Share on other sites More sharing options...
