TL* THE CONTACT OWNS A 2004 HYUNDAI XG 350. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT ILLUMINATED.

I WAS DRIVING AND RUSTED SUBFRAME COLLAPSED CONTROL ARM & RIGHT AXEL BROKE ALSO POWER STEERING BELT BROKE. I WAS ABLE TO GET OVER NEARLY HAVING AN ACCIDENT. I HAD MY CAR REPAIRED IN 2010 AS PER RECALL YET I TRIED TO PUSH FOR SUB FRAME REPLACEMENT OVER REPAIR AT THAT TIME WITH NO LUCK. I BELIEVE THESE SUB FRAMES THAT WERE REPAIRED SHOULD BE REPLACED. THIS IS AN EXTREMELY DANGEROUS SITUATION I COULD HAVE BEEN KILLED! *TR
I HAVE A 2004 HYUNDAI XG350. MANY TIMES WHEN I LEAVE THE CAR OVERNIGHT (OR FOR A FEW HOURS) AND THEN START IT BACK AGAIN, THE GEAR DOES NOT ENGAGE WHEN I PUT IT IN DRIVE. WHEN I PRESS THE ACCELERATOR, AFTER A FEW SECONDS, THE GEAR ENGAGES SUDDENLY AND THE CAR LURCHES FORWARD. THE PROBLEM PERSISTS FOR THE FIRST FEW MINUTES WHILE I AM DRIVING. SO WHEN I AM MAKING A TURN, AGAIN THE CAR HAS TO START FROM ZERO, SO IT WOULDN'T MOVE FOR THE FIRST FEW SECONDS AND JUST JUMP FORWARD. THIS CAN BE VERY RISKY AT TIMES, ESPECIALLY ON TURNS. ONCE THE ENGINE IS HEATED UP, THERE IS NO PROBLEM. I HAVE ALSO FOUND OTHER PEOPLE FACING SAME ISSUE BUT NOT FIX FOR THIS PROBLEM YET. I WISH A CLASS ACTION LAWSUIT COULD BE FILED AGAINST HYUNDAI. *TR
I'M A SINGLE MOM AND HAVE NO FAMILY HERE IN CT. TO HELP ME OR GUIDE ME IN THIS SORT OF THING. MY CAR STARTED MAKING A KNOCKING NOISE UNDER THE HOOD. I DIDN'T KNOW WHAT IT WAS SO I TOOK IT TO MY MECHANIC. IT TOOK A COUPLE OF DAYS BEFORE SOME ONE THERE COULD LOOK AT IT. HE TOLD ME IT WAS AN ENGINE KNOCK AND SAID I SHOULD TAKE IT BACK TO THE DEALERSHIP TO GET IT FIXED. BY THE TIME I CONTACTED KEY IN MILFORD CT, MY CAR WAS OUT OF WARRANTY BY EIGHT DAYS. AND THAT'S ALL THEY KEPT TELLING ME. KEEP IN MIND, I BROUGHT THE CAR TO MY MECHANIC THE DAY BEFORE THE WARRANTY EXPIRED. KEY CHARGED ME 105.00 TO DETERMINE IT WAS IN FACT AN ENGINE KNOCK,AFTER I TOLD THEM MY MECHANIC TOLD ME WHAT IT WAS. KEY HAD NO LOANER CAR TO LEND ME WHILE MY CAR WAS THERE. LATER I FOUND OUT THERE WAS A WAITING LIST FOR LOANERS. NO ONE OFFERED TO PUT ME ON THE LIST AND NO ONE TRIED HELPING ME WITH A RENTAL. I PAID FOR A RENTAL THE ENTIRE WEEK THEY WERE PLAYING GAMES WITH ME WANTING TO CHARGE ME 10,360.00 FOR A NEW ENGINE AND WANTED TO CHARGE ME AN EXTRA 380.00 TO FIND OUT WHAT EXACTLY WENT WRONG WITH THE ENGINE, BEFORE THEY DECIDE TO REPLACE IT. NO ONE IS GIVING ME ANY GUARANTEE THAT THE WARRANTY WILL BE GRANTED. I BOUGHT MY CAR THERE 9/15/06 HAD MY CAR FOR THREE YRS,IT'S A 2004 XG350 WITH 46000 MILES ON IT. IT SOUNDS TO ME LIKE THE ENGINE HAD A DEFECT. EVERYONE ELSE I SPOKE WITH SAID THE SAME THING. I CONTACTED THE MANUFACTURE COMPANY AND NO ONE WAS TRYING TO HELP ME. I TOOK MY CAR OUT OF KEY AND BROUGHT IT BACK TO MY MECHANIC TO HAVE THE ENGINE REPLACED. I AM LOOKING FOR SOME SORT OF REIMBURSEMENT FROM KEY FOR ALL THESE GAMES THEY WANT TO PUT ME THROUGH, TRYING TO RIP ME OFF. MY CAR WAS IN FACT IN THE SHOP THE DAY BEFORE THE WARRANTY RAN OUT, MARCH 14, 2009. I HAVE ALL OF MY MAINTENANCE RECEIPTS AND RECORDS. KEY CHECKED ALL OF THE CARS FLUIDS AND EVERYTHING WAS CLEAN. I DON'T THINK ENGINES GO BAD OVER NIGHT. CAN SOME ONE HELP ME? *TR
DT*: THE CONTACT STATED WHILE TRAVELING VARIOUS SPEEDS, THE CHECK ENGINE LIGHT ILLUMINATED 6 DIFFERENT TIMES. THE VEHICLE WAS TAKEN TO THE DEALER ON 6 OCCASIONS, BUT THE PROBLEM COULD NOT BE DETERMINED. ON ONE VISIT, THE PCV VALVE WAS REPLACED, BUT THE PROBLEM PERSISTED. ON THE OTHER 5 VISITS, THE VEHICLE'S CODES WERE RESET, BUT THE PROBLEM PERSISTED.
DT*: THE CONTACT STATED THE VEHICLE INTERMITTENTLY LOST POWER WHILE DRIVING AT SPEEDS ABOVE 40MPH. THE VEHICLE RESUMED POWER AFTER BROUGHT TO A STOP. THE ONLY WARNING INDICATOR IS THE TCS LIGHT FLASHING DURING THE REDUCTION OF SPEED. THE VEHICLE WAS TAKEN TO A SERVICE DEALER TWO MONTHS AGO AND THE DEALER REPLACED THE FUEL PUMP, FILTER AND LINES. THE PROBLEM BECAME WORSE AND THE VEHICLE WAS RETURNED TO THE DEALER WHO RECOMMENDED GETTING A WHEEL ALIGNMENT AND TIRE ROTATION. THIS WAS COMPLETED AT AN INDEPENDENT REPAIR SHOP, BUT THE PROBLEM CONTINUES. THE VEHICLE HAS NOT BEEN RETURNED TO THE DEALER FOR FURTHER INSPECTION.
DT*: THE CONTACT STATED WHILE CHANGING LANES, THE ENGINE AND TRANSMISSION DID NOT RESPOND TO ONE ANOTHER. THE VEHICLE WOULD NOT ACCELERATE OR DECELERATE. THE DEALERSHIP WAS UNABLE TO DUPLICATE THE PROBLEM.
