Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, thanks for posting
Not knowing what the shop has actually done or checked I have to start with some basic questions, have you checked the following yourself?
Make sure no lights are staying on, dome lights or trunk light
tail lights or brake lights or side marker lights do not stay on
If any aftermarket accessories are installed (GPS,audio equipment or amplifier,add on security systems etc) disable or disconnect them and see if it helps.
After that the actual current draw on the battery should be tested with a digital volt/ohm/ammeter connected in series with one of the battery posts and the cable, if you want to do this I can help with that providing you have the meter I mentioned.
