NHTSA Complaint #10165481 — 2001 HYUNDAI XG300

1. HAVE HAD BRAKES REPLACED AND ROTORS RECALIBRATED TWICE AND STILL HAVE VIBRATION UPON BRAKING. DEALERSHIP SAYS I'M NOT BRAKING PROPERLY AND CAUSING BRAKES TO OVERHEAT, WHICH CAUSING ROTORS TO WARP. I'VE BEEN BRAKING THE SAME WAY FOR 35 YEARS AND NEVER HAD THIS PROBLEM. 2. AIR CONDITIONER STILL DOES NOT COOL PROPERLY AND HAS BEEN IN SHOP SEVERAL TIMES. DEALERSHIP SAYS THERE IS A LEAK IN THE A/C COOLANT, BUT THEY CANNOT FIND IT. 3. CAR CONTINUALLY STUTTERS AT HIGH SPEEDS, DEALERSHIP HAS REPLACED NUMEROUS PARTS, BUT PROBLEM PERSISTS. 4. ENGINE BEGAN MAKING CLACKING NOISE ABOUT 2 MONTHS AGO. DEALERSHIP SAID BAD GAS WAS CAUSE, BUT HIGH-GRADE GASOLINE HAS NOT FIXED PROBLEM. DEALERSHIP SAID I NEEDED A TUNE-UP, BUT THAT DID NOT FIX PROBLEM. DEALERSHIP SAYS THEY CANNOT HEAR NOISE, BUT NOISE IS CLEARLY AUDIBLE WHEN ACCELERATED AND CLIMBING HILLS (2-4 RPMS). DEALERSHIP STILL SAYS THEY DON'T HEAR A PROBLEM AND CANNOT FIND ANYTHING WRONG. THIS IS OF MAJOR CONCERN TO ME, AS I'M AFRAID THE ENGINE WILL BLOW UP WHILE ON A MAJOR HIGHWAY. 5. AIRBAG LIGHT CAME ON ABOUT A MONTH AGO, AND WON'T GO OFF, ALTHOUGH NOTHING IS WRONG IS AIRBAGS. 6. RADIO HAS A SHORT THAT CAUSES RADIO TO GO ON AND OFF INTERMITTENTLY. IF A CD IS PUT IN THE CD PLAYER AND LEFT THERE WHILE RADIO IS IN USE, THE RADIO WORKS FINE. 7. THIS CAR HAS BEEN IN THE SHOP SO MANY TIMES SINCE IT WAS PURCHASED IN DECEMBER OF 2001, I CAN'T FIT THE REPAIR AND WORKORDER SHEETS IN THE GLOVE COMPARTMENT ANY MORE, AND THE SERVICE TECHNICIANS KNOW ME BY NAME AND SIGHT. *NM
