Owner Complaints (5)
Your air conditioning system has been leaking and not cooling for years. You believe your car should be covered under a special warranty recall for evaporator core icing issues, but your VIN was apparently excluded from the recall notice despite being eligible. A mechanic has diagnosed a faulty evaporator coil as the cause. The fix will likely involve replacing the evaporator core and potentially reprogramming related systems.
