Hello. I purchased my Highlander in the beginning of 2018, but it is a model year 2017 (brand new). I have only 55,000 miles on it and out of the blue all of my AWD, Traction COntrol and check engine lights came on. I am being told that it needs a whole new head, etc. It is still under warranty thanfully but has anyone ever heard of having these major issues on a vehicle that primarily sits in a driveway 85% of the time?
