I had an issue with my brothers 2013 Toyota Sienna. The battery light came on and when I had the system checked it said the alternator was bad. I replaced the alternator to resolve the issue. After I was done putting everything back together I went start the car, and all the warning lights went off like a xmas tree. The VSC, TRAC, Battery, BRAKE, EPS all lit up and the power steering was not working. I had to jump start the car due to the battery level being so low. I had no clue what was wrong. I drove the car around the block, and still had the issues. I finally asked my brother to take the battery to Autozone and have it fully charged. When we put the battery back in and started the car everything was back to normal. I've never seen anything like this, so thought I would throw it out there in case someone else runs into this issue.Hi all, have a 2012 Sienna LE. Last night all of the dash lights came on and the speedo stopped working. Clicked around many sites trying to figure out what would be. Unplugged batter several minutes and lights came back on. Interesting thing is if I start the van up with the AC and fan on, the lights don't come on for several minutes driving. If I start the van w/o the AC and Fan on then the lights come on right away and the speedo doesn't work.
Don't know if these other factors play into it, but for full disclosure here..wife hit a deer jumping through air and back foot of the deer went through the windshield. Van sat in driveway for about 2 wees before finall got fixed. Went to drive it yesterday and noticed all the lights. Windshield guy says only one heat sensor in windshield and should not impact any of this stuff. No other damage done to the van fortunately!
I've tried resetting all of the lights with the jumper method and greased up the gas cap but lights still come back on. I've read multiple horror stories on the different sites about how dealer charged upwards of $2400 and problems persisted. Don't have the cash for that and just don't want that!.
Any help would be appreciated!
