 Purchased a certified used Highlander Hybrid 2011 5 months ago and it's had so many problems. Weird noises from the wheels, steering wheel knocking and dvd player clicking! Had the axles replaced, the spline replaced and most recently the transaxle! It only had one owner previously and 75k with all regular scheduled maintenance. I've only been able to get 20-22mpg! The dealer can't figure out the weird braking noise and they have been terrible in getting back to me. Now I'm stuck with this car with issues still unresolved. When accelerating, the car sounds like a diesel truck! Anyone else experience this?
