What owners say about the electrical system
Verbatim from NHTSA complaints, newest first
“Car has a B1448 (ACTIVE) Passenger Occupant Detecting System (PODS) Circuit Fault Related to the passenger detecting pad in the front passenger seat problems started at 120,000 miles”
“The car was parked and turned off, not being driven and ignited on its own. The entire front end of the vehicle was on fire, according to the fire department it was some type of electrical short that started the fire. Vehicle was totaled out as it was a complete loss.”
“Just about 2 months ago i exit my vehicle after parking up. As i exit i smelled a burning smell and heard sparks so i stepped away from vehicle asap and then the horn start honking and lights flashing on own. Then the car started up by itself and started to run without me in car and keys in my hand. Police came from noise distubing and took the battery off to stop. After that i couldnt start car so had towed in shop for 5 weeks. Hot out of shop and can start now but now my a.c. and windows doesnt work because mechanic said that something keep blowing those fuses out and if he puts yhem back in then the car will go back to not starting. I am guessing this is part of the recall.”
“TL* THE CONTACT OWNS A 2008 HYUNDAI SONATA. THE CONTACT TOOK THE VEHICLE TO CROWN HYUNDAI (5301 34TH ST N, ST. PETERSBURG, FL 33714, (888) 727-9161) REGARDING THE REAR BACK-UP SENSORS AND AN UNKNOWN NHTSA RECALL RELATED TO THE ENGINE CONTROL MODULE (ECM) CLUSTER. WHEN THE DEALER ATTEMPTED TO UPDATE THE ECM CLUSTER, THEY DISABLED THE VEHICLE. THE DEALER KEPT THE VEHICLE FOR TWELVE DAYS, BUT DID NOT PROVIDE A REMEDY. THE MANUFACTURER WAS CONTACTED AND PROVIDED A LOANER VEHICLE. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 3,000.”
“2008 HYUNDAI SONATA 6CYL DOHC 3.3L / 152812 WATER PUMP WENT OUT. REPLACED IT. THEN WATER ENDED UP IN THE OIL THAT GOT INTO THE LIFTERS. ENDED UP GETTING ANOTHER MOTOR. THEN MY A/C STOPPED WORKING (DIDN'T BLOW COOL OR COLD AIR). CHANGED OIL AND OIL FILTER MYSELF ALONG WITH THE OIL SENSOR ( CONNECTED TO OIL FILTER SPOT) THAT WAS LEAKING BAD AS LONG AS THE CAR WAS RUNNING.I WAS DRIVING ON THE INTERSTATE, IN FRONT OF A LOADED 18 WHEELER, DRIVING 75 THEN MY CAR JERKED REAL HARD THEN DROPPED DOWN TO 40. I HAD TO PULL OVER ILLEGALLY TO KEEP FROM GETTING HIT BY THE TRUCK. AS I WAS CATCHING MY BREATH I TURNED THE CAR OFF. WHEN I STARTED IT BACK UP IT MADE A WEIRD TICK NOISE. HAVEN'T HEARD THAT NOISE SINCE. WHEN I PULLED OFF IT HESITATED TO CHANGE GEARS FROM 2 TO 3. IT FINALLY CHANGED AND DID NOT COME OUT OF 3RD. GOT IT TOWED HOME. HAD MY MOMS BOYFRIEND TO CHECK THE TRANSMISSION. HE DROVE IT AND IT WAS FINE. NEXT MORNING STARTED CAR AND IT SOUNDED LIKE A VACUUM CLEANER. (LOW VOLUME) FINALLY IT WENT AWAY. WHEN I HEADED TO WORK, IT HESITATED AT FIRST. THE VACUUM NOISE CAME BACK AND WAS LOUDER. THEN I SPED UP TO 50, IT HARD JERKED AGAIN, AND STAYED IN 3RD GEAR. AS I WENT…”
“I HAVE THE 3.3L V6 ENGINE THAT IS ALSO IN TWO OTHER VEHICLES MADE BY HYNDAI. BOTH OF THOSE VEHICLES HAVE BEEN RECALLED DUE TO THE FACT THAT THE ENGINE LEAKS OIL FROM A FAULTY GASKET AND DRIPS ONTO THE ALTENATOR. THIS CAUSES THE ALTERNATOR TO FAIL PREMATURELY AND OFTEN WITHOUT WARNING. I AM ON MY THIRD ONE NOW AND IT IS SHOWING SIGNS OF FAILURE. THIS CAN BE EXTREMELY DANGEROUS ON THE FREEWAY WHEN THE VEHICLE ALL OF A SUDDEN LOSES ALL ELECTRICAL POWER. THIS SCENARIO HAS HAPPENED TO ME TWICE NOW. NO HEADLIGHTS, NO DASHBOARD INDICATORS, NO BRAKE LIGHTS, NO TURN SIGNALS. AT 70MPH THIS CREATES AN EXTREMELY DANGEROUS SCENARIO.”
