Lisa Sedwick Posted March 6, 2023 Share Posted March 6, 2023 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?

Toyota Owners Club Posted April 14, 2023 Share Posted April 14, 2023 Have you had the battery checked for condition and charge as this can cause the systems to go offline Quote Link to comment Share on other sites More sharing options...
