Unquestionably this is the worst GM product in recent history. Seats are like setting on a wood box, engine destroyed itself at 11,000 miles, ABS/Traction Control did not work for over 8 weeks. The horn button requires over 50 pounds to activate. It won't pull itself on level road in 4th gear. The seats will not adjust to anyone large or small. Middle seats are close to front even for a short person. The rear seat is not adjustable. We have owned over 25 GM vehicles over the last 30 years, this one is deplorable. The 1999 Oldsmobile we formerly owned was far superior to the Terraza.
