My 12 volt was discharged, now have hybrid failure message

you'll need to fully charge the dead battery and try it again.

 

Always be in Ready if you are using any electricity.

If you are in Ready, it is charging the 12 volt battery. No need to actually drive it anywhere or rev it up, just be in Ready for about an hour.

With luck it may not have damaged the 12 volt battery but if it is still funky in 2 weeks, get a new 12 volt battery.

 

i thought the gen 4 battery was a little more robust. hopefully it won't be as damaged as a gen 3.

 

How was the visit? Any updates?


iPhone ?

 

You'd think those guys would learn. It should be one of the mandates, for any service that's going to leave the car open for a protracted time: have the battery on a maintainer, and/or use clamps to spoof a closed door condition. There is NO excuse for them running the car to listen to the radio.

They can run the car's 12 volt battery down so easily, and if you're really unlucky: screw up the jump start, reverse the leads, which can leave you with a broken car.

 

Maybe get a digital load test done on the 12 volt. At the least a check of the at-rest voltage. See what they've left you: the 12 volt may be partially recovered but impacted.

If you're interested in prosumer level toys and DIY, the Solar BA5 will do the load test.

And maybe leave a comment on Yelp regarding this. Tinters are notorious, valets a close second. Again: if those guys get their hands on a set of jumper cables (basically to try to mask what they've done) they can doing some seriously expensive damage if they hook up wrong.

Besides leaving doors open for protracted time, likely with dome light ablaze, there is no excuse for them helping themselves to your radio, running the car in accessory mode!

 

Maybe the car did not want to go to the vet (dealership).
