2003 Toyota Highlander SUV Limited AWD 4dr SUV (3.0L 6cyl 4A)
New Owner-Wierd Issues
 I just purchased the Toyota Highlander 2003 and upon purchasing the vehicle I was very happy.The check engine light came on shortly after purchase and apparently the cause is a bad "ECM" board in the SUV.I am not sure if this is common but I have experienced this problem.I love the vehicle otherwise and plan on driving it for a while.Currently at 82K hope it lasts to 200K without major repairs.
