Open the full vehicle complaint log (all categories)TL* THE CONTACT OWNS A 2010 HYUNDAI AZERA. WHILE DRIVING 45 MPH, THE VEHICLE STALLED AND ALL THE INSTRUMENTAL PANEL INDICATORS ILLUMINATED. THE CONTACT WAS ABLE TO COAST THE VEHICLE ONTO THE ROAD SHOULDER. THE VEHICLE WAS TOWED TO THOMPSON HYUNDAI (1000 MERRITT BOULEVARD, DUNDALK, MD 21222, (410)-288-5700) WHERE IT WAS DIAGNOSED THAT THE VEHICLE STALLED BECAUSE THE VALVE COVER GASKET LEAKED OIL ONTO THE ALTERNATOR. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 69,500. *TT THE ISSUE IS A KNOWN PROBLEM. THESE LAMBDA V6 3.3 LITER AND 3.8 LITER ENGINES ALL HAVE THESE SAME ISSUES, REGARDLESS OF WHAT VEHICLE THEY ARE IN. VERACRUZ, AZERA, SONATA, SEDONA, ENTOURAGE, AND SO ON. THE VALVE COVER'S LEAK OIL ONTO THE ALTERNATOR AND CAUSE THEM TO FAIL, CAUSING THE ENTIRE VEHICLE TO LOSE POWER AND CONTROL WHILE DRIVING. SUPER UNSAFE. THIS IS EXACTLY WHAT HAPPENED TO ME. FORTUNATELY I WAS ONLY BY ROUTE 1 HERE IN MARYLAND AND NOT ON 95, 495 OR SOMEWHERE LIKE THE BAY BRIDGE. I HAVE PICS TAKEN THAT AFTERNOON AT THE GAS STATION I SWUNG INTO IN JESSUP TO SHOW YOU WHAT HAPPENED. THESE ARE CONSISTENT WITH THIS ISSUE ACROSS THIS TYPE OF ENGINE.*JB *BF CONSUMER REPLACED THE BATTERY AND ALTERNATOR. *JB
