NHTSA Complaint #11279975 — 2003 CHRYSLER PT CRUISER

I REPLACED MY VEHICLES BATTERY 2 DAYS AGO(NOV 12, 2019)(VERY OLD BATTERY AND WITH THE COLD IN MASSACHUSETTS IT NEEDED TO BE CHANGED). NOW WITH A PROPERLY FUNCTIONING BATTERY THE VOLTAGE REGULATOR IN PCM (NOT ALTERNATOR) IS SIGNALING ALTERNATOR TO RAISE CHARGING VOLTAGE INTERMITTENTLY TO AS HIGH AS 17.1VOLTS, BUT HAS BEEN FREQUENTLY BOUNCING BETWEEN 14.1V -16.7VOLTS. THIS INCREASE OF VOLTAGE TO A UNSAFE LEVEL CAUSES ALL ELECTRICAL ACCESSORIES THAT ARE IN CONNECTED TO THE CHARGING SYSTEM AND ARE OPERATIONAL TO FLASH/ FLICKER. EXTREMELY DISTRACTING AT NIGHT WITH HEADLIGHTS AND DASHBOARD FLASHING/ FLICKERING. AFTER A LOT OF RESEARCH I FOUND OUT THE PCM NEEDS TO BE REPROGRAMMED WITH THE PROPER UPDATED FIRMWARE IN ORDER TO FIX THE FACTORY WEAK PARAMETERS. I SPOKE WITH A SERVICE MANAGER TODAY(NOV 14,2019) AT MY LOCAL CHRYSLER DEALERSHIP (CENTRAL JEEP CHRYSLER DODGE RAM FIAT @ 56 BOSTON PROVIDENCE TPKE, NORWOOD, MA 02062) ABOUT THE PROBLEM AND ASKED TO HAVE MY PCM REPROGRAMMED SINCE ONLY THAT SPECIFIC MODEL CAR MANUFACTURES SERVICE SHOP WILL HAVE THE CAPABILITY AND PCM FIRMWARE TO REPAIR IT. THE MANAGER REFUSED TO DO ANY WORK ON MY CAR SINCE HE SAID, "I WONT TOUCH CARS OLDER THAN 10YEARS AND CLOSE TO 100,000MILES". THEN ASKED IF I WAS EVEN A CUSTOMER AT THAT SPECIFIC LOCATION, SAYING NO AGAIN AFTER I SAID I WASN'T. THERE IS NO OTHER OPTION THAN THE FACTORY DEALERSHIP TO FIX A FACTORY FLAWED PCM, WHICH MAKES THE RISK OF MY BATTERY EXPLODING DUE TO THE INCREASED REGULATED VOLTAGE VERY LIKELY. THIS PROBLEM ISN'T NEW TO CHRYSLER SINCE THEY HAVE ISSUED SEVERAL TSB(S) IN MY SPECIFIC VEHICLE AND THIS EXACT PROBLEM: 18-112-16 18-026-03 REV.A 18-016-03 18-020-04
