NHTSA Complaint #11067344 — 2017 CHRYSLER PACIFICA

ON LONG TRIPS (GENERALLY GREATER THAN1 HOUR) THE ACC/FCW (ADAPTIVE CRUISE CONTROL/FRONT COLLISION WARNING SYSTEM) SYSTEM FAILS INTERMITTANTLY (WITH OR WITHOUT THE CRUISE ACTUALLY BEING ACTIVE) AND THE DASH DISPLAYS "ACC/FCW UNAVAILABLE SERVICE REQUIRED". ONCE HAVING FAILED, THE SYSTEM CANNOT BE RESET WHILE CONTINUING TO DRIVE, BUT TURNING THE ENGINE OFF AND RESTARTING WILL RESET IT. LOSING THESE SYSTEM PRESENTS A SAFETY HAZARD AS THE FCW IS NOT ONLY A WARNING SYSTEM BUT CAN ACTUALLY STOP THE CAR IN AN EMERGENCY SETTING. LOSING THE ACC (ADAPTIVE CRUISE CONTROL) ACTUALLY MEANS LOSING ALL CRUISE CONTROL, WHICH IS NOT ONLY ANNOYING BUT CAN EASILY LEAD TO EXCEEDING SPEED LIMITS AND/OR CONSTANTLY CHECKING THE SPEEDOMETER SETTING RESULTING IN REDUCED DRIVER SITUATIONAL AWARENESS. THE BIGGEST PROBLEM IS THAT THE FAILURE THROWS NO CODES THAT CODE READERS AT AUTOZONE OR CHRYSLER CAN SEE AND CHRYSLER SERVICE SAYS THERE IS NO FIX WITHOUT A CODE. INABILITY TO DIAGNOSE AND FIX THIS IMPORTANT ENHANCED SAFETY SYSTEM IS A SAFETY FAILURE AT CHRYSLER. NOTE THAT THE FAILURE HAS OCCURRED IN A VARIETY OF SITUATIONS--DAY/NIGHT/SUN/RAIN/CLOUD/SNOW/DIRTY/CLEAN/FAST/SLOW.
