Example complaints
One per model year, chosen for length and detail. Personal details are removed. They are consumer reports, not findings.
2008: “Third row seat would not lock in position, either up for seating or down for cargo. The lack of locking effected the motor which raises and lowers the seat to lock position. Dealer and/or mfg. Claimed the seat frame is prone to bending. I had to pay to have it fixed. When I noted this sounds like a safety issue they offered to pay 75% for the part and discount on labor.”

I had to come to a complete stop to regain control. A passerby stopped and said it looked like the car lifted 2 feet in the air. After restarting the car multiple times the air suspension has not recallibrated. My back and neck are sore. I called my fiance to meet myself and the baby so we could get home. I was not going to risk shaken baby syndrome. …”
