ENGINE

I bought the car new, it has 39k miles on it. 5k miles ago while repairing the water pump under the 10 year powertrain warranty, I reported to the dealership the engine was making bad knocking/grinding sounds at startup and the oil consumption was high. The dealership dismissed this as "normal" for this car. 2 weeks ago the engine seized up without warning, no loss of power or harshness, no engine check light or low pressure warning. I had just left the I15 in rush hour traffic traveling at 70mph. The starter could barely turn the engine, I thought it was a flat battery. After some time I managed to restart the engine that now sounded like a machine gun and limp a few miles home. I tried replacing the oil, which I do on a regular basis, and it contained metal fragments. The warranty expired in Dec 21 but I still contacted the dealership. They have inspected the car and report engine damage requiring $3,200 of parts. Both the dealership and myself have contacted Hyundai Corp. and opened a Consumer Affairs Case on 5/25. Yesterday, 5/24, the case manager spoke to me to get details and obtain evidence I might have including original proof of ownership (documents he should already have). He told me he would have a decision in 2 to 4 weeks. I asked about leaving the car at the dealership, and he replied that it was the dealerships decision, but I would probably need to remove it. I would consider the car dangerous to drive, but the case manager does not seem to consider this and my impression is that Hyundai will refuse any responsibility for this problem. After googling this, I see you have sued Hyundai for what appears to be exactly the same manufacturing problems in other engines from the same time and wonder if these should also apply to the 5.0 liter engines. Has Hyundai acknowledged a problem with these engines and corrected it? If so, why has a recall not been issued, and I not charged for their manufacturing mistake? The dealership has rebuilt the engine and returned my car, charging me $3400.

MY VECHILE STALLS WHILE DRIVING AT VARIOUS TIMES. THIS COULD CAUSE A SERIOUS ACCIDENT IN WHICH LIVES COULD BE LOST . THIS EEMS TO BE PROBLEM WITH THE GENESIS FROM 2012 TO 2016 FROM MY RESEARCH. I AM NOT THE ONLY OWNER WITH THIS PROBLEM . THE DEALERS CANT FIND THE PROBLEM OR WHY IT IS OCCURING . THE DEALERS GIVE YOU NUMEROUS REASONS AS TO WHAT MIGHT BE THE CAUSE OF THIS PROBLEM, BUT THEY ARE NOT SURE . THIS COULD COST A CONSUMER $1000 OF DOLLARS JUST TO FIND OUT WHAT THE PROBLEM IS . THIS OCCURS WHEN JUST DRIVING DOWN A STREET, ON CURVES OR GOING STRAIGHT. I HAVE NOT HAD AN ACCIDENT YET! IM TRYING TO AVOID THIS .THIS OCCURS WHEN MY GAS TANK GETS LOW , THAT IS WHAT I HAVE NOTICED .

AT 31,500 THE AIR CONDITIONING COMPRESSOR FAILED. THERE ARE NUMEROUS POSTS FROM OTHER OWNERS ABOUT THE COMPRESSOR FAILING. HYUNDAI WILL NOT SHARE THE TSB'S ABOUT THIS KNOWN ISSUE. AN AC COMPRESSOR SHOULD LAST AT LEAST 50,000 MILES AND IN REALITY A LOT MORE MILES. THE VEHICLE WAS IN MY GARAGE PARKED AND THE COMPRESSOR WENT BAD. I FOUND OUT THE NEXT TIME I STARTED THE CAR AND THE COMPRESSOR DID NOT WORK. THE COMPRESSOR INSIDES WERE PLASTIC ACCORDING TO THE HYUNDAI MECHANIC JACK THAT WORKED ON THE CAR AT SAN TAN HYUNDAI. THE FEDERAL GOVERNMENT SHOULD NOT LET HYUNDAI SELL JUNK THEN CHARGE FOR REPLACEMENTS.

2012 GENESIS SEDAN CONSISTENTLY STALLS UNDER MEDIUM TO LOW SPEEDS WHILE BRAKING OR MAKING A TURN. ALL WARNING LIGHTS COME ON AND LOSS OF STEERING AND BRAKING OCCURS. CAR IS DIFFICULT TO CONTROL SAFELY WITHOUT USE OF EMERGENCY BRAKE DUE TO THE LOSS OF STEERING/BRAKING.

HYUNDAI GENESIS 2012 ENGINE STALLS IN TRAFFIC AT SLOW SPEEDS. AS I WAS SLOWING DOWN ONA CROWDED FREEWAY ON RAMP THE ENGINE DIED.

NHTSA complaint #11120910 — an unverified report by a vehicle owner.

ENGINE

ENGINE STALLED RANDOMLY AT LOWER SPEEDS, USUALLY WHILE TURNING. LOSE POWER STEERING AND BRAKES - EXTREMELY DIFFICULT TO CONTROL CAR AND UNBELIEVABLY DANGEROUS. IT HAS HAPPENED TO ME 3 TIMES AND MY 16 YEAR OLD DAUGHTER TWICE, ALL WHILE TURNING FROM A HIGHWAY OR HIGHWAY INTERSECTION. FORTUNATELY I HAD TOLD HER IT MIGHT HAPPEN TO HER AND WHAT TO EXPECT IF IT DID. GIVEN THE NUMBER AND CONSISTENCY OF OTHER COMPLAINTS FILED, IT IS EQUALLY UNBELIEVABLE THAT SUCH A SAFETY ISSUE HAS NOT BEEN INVESTIGATED. IT IS SO RANDOM THAT IT WILL BE VERY DIFFICULT TO REPLICATE, BUT GIVEN THE POTENTIAL FOR INJURIES OR DEATHS THIS IS AN UNACCEPTABLE MANUFACTURER PROBLEM.
