NHTSA Complaint #11543963 — 2017 CHRYSLER PACIFICA

Engine temperature suddenly rose to the point where an alarm appeared on the display (no prior warning or prior instance of this). Allowed temperature to cool, drove vehicle home gently. Subsequent examination showed coolant level in reservoir below minimum with no physical evidence of leakage. Obtained correct manufacturer-specified coolant, topped up and continued to monitor. Pattern developed where the coolant level would be at minimum after approximately 200 miles of driving, vehicle appeared to be operating normally otherwise. Continued to top up coolant level as necessary, still no sign of any physical leak. Vehicle then began to produce error codes for misfire on either Cylinder 1 or Cylinder 3 - no discernible “pattern” to the codes appearing or clearing. Vehicle was subsequently examined by an independent repair facility who determined that the cylinder head for cylinders 1, 3 and 5 is warped.
