2000 Hyundai Sonata electrical system problems

“MY HYUNDAI DEALER HAS REFUSED TO HONOR THEIR 100,000MILES, 10 YEARS WARRANTY" MANY TIMES THAT I BRING THE CAR TO BE FIXED UNDER THE WARRANTY SINCE THE CAR WAS ONLY 8YEARS OLD AND 76,000 MILES SINCE 2008. THEY REFUSE TO FIX THE PROBLEMS THAT I EXPERIENCED BY SAYING MY CAR IS NOT LISTED IN ANY RECALL CAMPAIGN. UNFORTUNATELY THIS YEAR, ON 10/11/12, I TOOK MY CAR FOR AN ANNUAL STATE INSPECTION FOR 2000 HYUNDAI SONATA AND IT FAILS THE SAFETY INSPECTION. HERE IS WHAT IT SAYS: ***VEHICLE MEMO*** VEHICLE IS UNSAFE TO DRIVE...REAR SUB-FRAME HAS HOLE ROTTED THROUGH... DUE TO THE CURRENT FINANCIAL SITUATION, I DON'T KNOW HOW I WILL GET THIS CAR FIXED BECAUSE THE CAR IS NOW 115,000MILES AND 12 YEARS OLD AND I DON'T KNOW IF THEY WILL FIX IT. THEY HAVE CONTINUOUSLY REFUSED TO FIX MY CAR UNDER WARRANTY EVEN WHEN IT WAS CLEARLY WITHIN THE WARRANTY PERIOD AND I WAS LUCKY THEN THAT I HAVE BEEN ABLE TO PAY THE FIXES OUT OF POCKET BUT I DON'T HAVE THE LUXURY OF PAYING OUT OF POCKET THIS TIME. I AM IN NEED OF MIRACLES NOW. *TR”

“TL* THE CONTACT OWNS A 2000 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 10- 35 MPH, THE ENGINE STALLED WITH THE ILLUMINATION OF THE CHECK ENGINE WARNING INDICATOR. THE WARNING INDICATOR REMAINED ILLUMINATED UNTIL THE ENGINE WAS TURNED OFF. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT THE MASS AIR FLOW SENSOR WOULD NEED TO BE REPLACED. THE FAILURE RECURRED WHENEVER THE ENGINE WAS IN OPERATION. THERE WAS A RECALL RELATED TO THE DEFECT UNDER NHTSA CAMPAIGN ID NUMBER 00V259001 (ELECTRICAL SYSTEM: WIRING); HOWEVER THE RECALL EXPIRED. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 120,000. UPDATED 03/14/12*LJ”

“I HAVE A 2000 HYUNDAI SONATA. I HAVE HAD SEVERAL SENSORS REPLACED IN THIS CAR ALREADY. IT IS SOMETHING ELECTRICAL OR ANOTHER SENSOR, GO FIGURE. MY WIPERS STOPPED WORKING, AND MY WIPER FLUID PUMP ALSO WENT OUT. HAD LOCAL AUTO SHOP REPLACE WIPER FLUID PUMP, THEY TRIED WHATEVER THEY COULD, THEN THE WIPERS WOULD NOT STOP WORKING,SO THEY TOOK OUT THE RELAY SWITCH.THEN MY WIPERS START WORKING AND I CAN TURN THEM OFF/ON WITH OUT THE RELAY SWITCH IN. MY CAR POWER LOCKS ARE NOT WORKING EITHER, WHICH THEY DID BEFORE. THEN MY CAR WOULD NOT START FOR NEXT THREE/FOUR DAYS, HAD TO HAVE IT JUMPED EACH DAY. SO I THOUGHT IT WAS MY BATTERY OR ALTERNATOR, HAD THOSE TESTED, IT IS NOT EITHER OF THEM. THEN MY CAR THE NEXT COUPLE OF DAY STARTS A LITTLE BETTER, BUT STILL BARELY STARTING, AND SOMETIMES WHEN I START MY CAR, THE POWER LOCKS LOCK AUTOMATICALLY. MY RADIO HAS ALWAYS ACTED UP BY TURNING OFF AND ON WHEN IT WANTS AND NOT SAVING THE STATIONS I SAVE EVERYDAY, BUT NOW IT GOES FROM A STATION TO MY CD TURNING ON, JUST BY ITSELF. I HAVE SEEN OTHER COMPLAINTS ABOUT THIS ON THE INTERNET, THERE IS SERIOUSLY SOMETHING WRONG WITH THE ELECTRICAL WIRING OR THE SENSORS OF THIS CAR, THERE…”

“TL*THE CONTACT OWNS A 2000 HYUNDAI SONATA. THE CONTACT WAS DRIVING APPROXIMATELY 25 MPH WHEN THE "CHECK ENGINE" WARNING LIGHT INDICATOR ILLUMINATED ON THE INSTRUMENT PANEL AND IMMEDIATELY, THE ENGINE STALLED. THE VEHICLE RESTARTED AND RESUMED NORMAL OPERATION. THE WARNING INDICATOR REMAINED ILLUMINATED UNTIL THE ENGINE WAS TURNED OFF. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE FAILURE WAS CONTRIBUTED TO THE MASS AIR FLOW SENSOR. THE VEHICLE WAS REPAIRED FOR THE MALFUNCTION. RECALL NUMBER 00V259001, ELECTRICAL SYSTEM, WIRING WAS RELATED TO THE FAILURE; HOWEVER, THE VIN WAS EXCLUDED. RECENTLY, THE FAILURE OCCURRED WHENEVER THE VEHICLE WAS IN OPERATION WITHOUT WARNING.

“I PULLED OUT INTO THE ROAD FROM A STOP SIGN AND MY CAR LOSS POWER AS THERE WAS ONCOMING TRAFFIC ALMOST COMING TO A COMPLETE STOP. I HAD TO COME COMPLETELY OFF THE GAS PEDAL AND STOP, AS I RESUMED THE CAR BEGAN JERKING AND SLOWING RESUMING SPEED. I WAS ALMOST REAR ENDED WITH MY KIDS SITTING IN THE BACK SEAT. THE ALSO DID THE SAME THING AGAIN AS I BEGIN TO DRIVE UP A INCLINE/HILL, IT LOSS POWER. I EXPERIENCE THIS PROBLEM AT LEAST 3-4 TIMES A WEEK. I HAVE RESEARCHED THAT THERE WAS AN ELECTRICAL PROBLEM IN 2000 HYUNDAI SONATA, V-6 CARS AND CONTACTED THE DEALERSHIP AND THAT STATED THAT MY CAR WAS NOT INCLUDED IN THE RECALL. I WAS ALSO TOLD THAT I HAD SEVERAL REPAIRS DONE FROM PREVIOUS RECALLS. I INFORMED THE CUSTOMER SERVICE PERSONNEL THAT I HAD NOT RECEIVED ANY NOTIFICATIONS IN THE MAIL REGARDING RECALLS. I AM VERY CONCERNED FOR THE SAFETY OF MY FAMILY WHILE DRIVING THE VEHICLE AS WELL AS MY OWN. COULD SOMEONE PLEASE HELP ME IN RESOLVING THIS ISSUE? I DID LET CAPITAL HYUNDAI LOOK AT MY VEHICLE A WHILE BACK AND WAS TOLD THAT MY CAR NEED TO HAVE SOME SENSORS REPLACED AT MY OWN EXPENSE. IF THERE WAS A RECALL ON THE 2000 MODEL, SHOULD THEY NOT COVER THIS MATTER? IF THE…”

“TRANSMISSION INPUT SPEED SENSOR FAILURE, THIS PROBLEM IS SHOCKINGLY ALL OVER THE INTERNET, THE SENSOR FAILS AND IF YOUR ON THE HIGHWAY, YOU SUDDENLY SLAM DOWN IN SPEED TO ALMOST HALF YOUR PREVIOUS SPEED WITH A LOUD BANG AS THE TRANSAXLE JUMPS FROM 4TH GEAR TO 2ND GEAR AND THE ENGINE REDLINES. DUE TO THE FAILED SENSOR TELLING THE TRANSAXLE TO DOWNSHIFT IMPROPERLY. A INEXPERIENCED OR LESS CAPABLE DRIVER MAY HAVE BEEN THROWN OUT OF CONTROL FROM THE SHEER FORCE OF THE IMPACT WHEN THE TRANSAXLE MIS-SHIFTS FROM 4TH TO 2ND WHEN THE SENSOR MALFUNCTIONS. *TR”
