Worst thing I ever bought

23,000 miles and tires are bald. Can't drive it over 50 without the car slipping with new tires. The screen has went out on me twice and it seems to not shift well when first taking off. I'm mostly disappointed in the way it handles on wet, icy and snow covered roads. The rear end sliding and it sways all over the road. If the wind is blowing it is awful. sucks

Seats are not comfortable at all. Worst vehicle I have ever driven on slick roads. The computer wants to take over and leave you stranded. DONT BUY A TERRAIN.

After buying, I put the back windows down for some fresh air and what happened is what is called helicopter effect. It was so noisy my ear drums hurt. And the doors and vehicle shook so bad I thought the doors were going to come off. This happens only at high speeds on the highway. would I buy this vehicle again-----absolutely not.

Have owned for 4 and a half years. Literally no issues. Very good gas mileage and the 9 speed electronic transmission is one of the smoothest shifting I’ve ever owned. The ride is very good also.
