This car is dangerous. Driving 65mph on freeway when every service and warning light went on. Replaced entire instrument cluster and replace ipc, could have killed us and others. Also engine was removed to repair engine front cover leak at 39,000, now at 85,000 same leak repair is required at cost of $2926. That means every 40,000 miles you need to spend $3000 and have engine removed. Power steering always made whining noise which I was told is normal. At 85,000 was told steering rack and pinion gears need replacement and I am sure the pump needs replacement as well $2000. When driving on the freeway could not stop on exit without brake pedal being pushed all the way to floor, stabiltrak light on could have killed us or someone. Had to replace brake master cylinder. Water pump was leaking after engine was put back in from 1st repair of front cover engine seal. Timing chain has stretch you can hear it, but they only added thrust washers. Rear liftgate - while loading groceries lift gate free fell closed on daughters head. Was told rear lift gate shocks failed. Could have killed someone. This car is a death trap. Don't buy it.
