I have a 2015 Highlander. The vehicle has a slow battery drain. I have read many of the posts on this forum and I knew going in that these issues can be difficult to isolate. I took the vehicle to my local shop that does my normal maintenance. They tried to isolate the problem and think that it might be one of the door switches not remaining shutting off all the way so there is discharge.
Does anyone have experience with taking such a problem to Toyota? Do they have special equipment to help isolate the problem? When you get work done there I know it can be costly. I fixed a problem with my radio/nav system dashboard rebooting on its own. I found a link on this forum, downloaded some software, plugged the thumb drive into my Toyota and updated the system. Saved hundreds I think. I may have to go to Toyota as a last resort. Experiences that you have had will be very helpful. Thanks in advance.
