“On multiple occasions my wife's care has refused to srmtart with now answer from the dealership why, the brakes have been replaced by Fiat under warranty and they still squeak when in reverse, and lately it says there is a tire sensor that is damaged or low along with drive mode unavailable, this keeps us from using the awd system effectively, and Fiat said they fixed the issue once before and it came back within the week. …”
