NHTSA complaint #10874048, filed 2016-06, 87,000 milesEngine: “Takata recall I have had to make many repairs on this vehicle. However, now the lifters in the engine collapsed. The vehicle only has about 87,000 miles on it. This is unacceptable. There have been many complaints about this vehicle and the lifters collapsing. We are a one income family and the repairs to this vehicle are astronomical. Well over 3500.00 dollars. This vehicle is not drivable and has been sitting for a year now at my mechanics. The vehicle is of no use to me and has become a huge paper weight now. The worst part is I still owe on the vehicle too. …”
