    image.jpeg Hello folx!

    Reaching out after getting an oil change done @ Firestone. The next day, I felt the car shake slightly at a red light. It happened twice before the check engine light came on.

    The next day, the red triangle, yellow brake warning light, check engine, vsc lights and the red car at the top of the display screen were all on. After attempting to drive it back to Firestone, it turned off mid-drive as I was pulling into the mechanic. It is currently there now.

    I have checked and seen that it is not a problem with the inverter pump- the coolant is vibrating when I unscrew the cap and hose is vibrating to the touch. My battery reads at 0 when I check the info, it shows either one purple line or no lines and it reads as empty when car is on. When I went into maintenance mode, I was getting a 12.2v read while car was not in ready, just in acc or rest. Could this be a simple issue of recharging the battery? If so, could it be done via jump or should it be done another way?

    Battery is at least 3yrs old, car is 2004 w/ 152k miles on it. Hybrid battery replaces in April of this year.

    Thanks for all the help!

    Replaced with what? New or remanufactured?

    You need to get the diagnostic codes read. Those will tell you where you stand.

    Maybe they overfilled the oil

    New from the dealership. Firestone just called and said they can't get the car started and they checked the battery and it's fine. They are checking the codes now. I will update.

    Firestone says they can't get the car started but they checked the batteries and they were all fine. Funny thing is, the info was telling me the battery was drained and it was showing 12.2v at rest so, I know it's low. Now they're saying they can't get the car started at all and are towing it to the Toyota dealership today. I am almost certain it's a simple 12v battwry replacement. Thoughts?

    Previously you said the HV battery was at zero bars and now the ICE won't start. Sounds to me the HV is completely drained and will need the special Toyota charger to bring it back to life. It's my understanding that most dealers don't have these and will have to special order it.

    I'm inclined to agree that the 12v is drained. Would it need a charger or am I best to purchase a new 12v all together?

    At 3yrs old, it's on the cusp of starting the end of life phase but typically the further north you are the longer lead acid batteries last so it may still be fine and just need a charge. A load test will tell you if it's a gone'r.

    Firestone is so incompetent. They said they did not perform a load test and are now just getting the car towed to Toyota. Hopefully, they can help me a little more. I'm fairly certain it's the battery, I just want to know if I can charge it or if I need a new one completely. I'll keep you posted on what Toyota says. Thanks!

    I can't remember anything but problems with Firestone service. I still say the oil is overfilled

    Well, it's on it's way to Toyota now so, hopefully, someone competent will find out what's up. Feels like an easy fix to me, I hope. Should've known to leave Firestone when I asked if they knew hybrid cars and one guy still suggested the alternator was causing a battery drain. (-__-)

    12.2 volts is plenty to start the car. It's not battery related. You should still charge that up though

    Hmm... Hoping Toyota will let me know what's really going on. I was hoping it would be somethin simple like the pump or battery. Shucks

    Or the oil was overfilled, like JC said.

    I'll take that as an option, too... No word from Toyota tonight.

    Which in turn stopped the ICE and you limped to Firestone on electric which drained the HV traction battery (NOT the 12 V battery).

    Toyota will now need to externally charge the HV traction battery and clear the reluctant code to get the car going again.

    Who's paying for fixing it?

    Hopefully just a charge up and you're good to go.

    And why would you pay, when Firestone's (if it turns out they overfilled the oil) ineptitude caused the problem?
