My engine is blown. The extended warranty offered by hyundai does not cover the time period or mileage I've had deeming it useless. This is a serious problem and it should be addressed properly. I cannot drive this vehicle. I still owe on my loan. The warranty is not sufficient for the damages accrued regardless if I had signed up in time. This is dangerous, criminal and I'd like reimbursement.

I got a routine oil change at an old change place and then needed another one 2 1/2 weeks later. The employees at the shop informed me that my vehicle was burning through the oil extremely fast and that the oil dipstick was bare when they checked the oil level. They checked for leaks and found none. The very next day I started hearing a clicking noise coming from the engine and the check engine light was on. I took the vehicle to Autozone in order to run diagnostics on the vehicle to find the problem. The employee there said it was the knock sensor informing us that something is wrong with the engine. I then took the vehicle to a mechanic to see if the problem could be alleviated. The mechanic informed me that there was nothing he could do because of the manufacturing defects of this specific engine. He informed me of a number of filed complaints about this specific engine and it having the same exact problems. The mechanic also informed me that I should immediately stop driving the vehicle because the engine knocking and there is an extremely high risk of it blowing up. I had no idea this engine would do that and have been taking care of the vehicle through routine maintenance since I purchased the vehicle.

WHILE DRIVING, THE ENGINE MADE CLICKING NOISES AND ALL OF A SUDDEN THE CAR JUST DIED. ALSO, WHEN I TRIED STARTING THE VEHICLE SMOKE CAME OUT OF THE ENGINE. I WAS ADVISED BY A MECHANIC THAT THE ROD BEARINGS NEEDS TO BE REPLACED. CURRENTLY, THERE IS A RECALL IN REGARDS TO THE ROD BEARINGS BUT ONLY FOR 2015 AND 2016.
I HAD A KNOCKING IN MY ENGINE BEFORE MY CONNECTING ROD BEAR HAD PUNCTURED 3 LARGE HOLES IN MY ENGINE BLOCK. I HAD NO CHECK ENGINE LIGHT AND MY VEHICLE NEVER EVEN HIT 120,000 MILES. A SIMILAR PROBLEM HAD BEEN REPORTED ON HYUNDAI VEHICLES THAT ARE BEING RECALLED.
OIL LEAK FROM FAULTY REAR MAIN SEAL
I WAS LOSING OIL WITHOUT AN OBVIOUS OIL LEAK. THE PSI IN THE 3RD CYLINDER WAS 90 AND WHEN SPARK PLUGS WERE REPLACED THE NEW ONES WERE COVERED IN OIL. I WAS TOLD I NEEDED A NEW ENGINE. I CONTACTED HYUNDAI AND THEY TOLD ME TO TAKE IT TO A CERTIFIED HYUNDAI MECHANIC AND HAVE THEM DIAGNOSE IT AND SUBMIT A REPAIR ASSISTANCE REQUEST AS I WAS THE SECOND OWNER AND THE CAR IS 8 YEARS OLD WITH 80,000 MILES. IT COST $700 FOR THE DIAGNOSTIC AND I WAS TOLD I NEEDED A NEW ENGINE. HYUNDAI DENIED THE REPAIR ASSISTANCE REQUEST AND I HAD TO PAY $700 FOR THE DIAGNOSTIC. NEITHER THE REPAIR SHOP OR HYUNDAI THOUGHT TO TELL ME THAT I SHOULD DO AN OIL CONSUMPTION TEST BECAUSE DOING SO WOULD HAVE LIKELY MADE HYUNDAI RESPONSIBLE LIKE MANY OF THE OTHER ENGINE RECALLS THEY ARE DEALING WITH. I HAVE SINCE HAD TO REPLACE THE ENGINE MYSELF.
VEHICLE ENGINE MAKING KNOCKING SOUND WHILE IDLE AND WHILE IN GEAR. CHECK ENGINE LIGHT NEVER CAME ON. LOW OIL LIGHT NEVER CAME ON. OIL WAS LOW, SHOULDN'T HAVE BEEN DUE TO JUST HAVING OIL CHANGE, BUT NO LEAK UNDER CAR.
I am writing to formally file a complaint against Hyundai USA regarding the engine damage, defect caused by connecting rod bearing failure that I am experiencing with my 2012 Hyundai Veloster. Hyundai is fully aware that countless owners have experience the same issues and have sent letters detailing the problems. I have always choose a Hyundai affiliated dealership to have all my services and repairs done. It has always been more expensive, but I wanted my vehicle to be in good shape and believed that I would receive the best services through them. The problems with my vehicle started in late 2019 or early 2020 when I was driving with my family on the highway. It felt as if the car was about to fall to a sudden stop, and the speed suddenly started decreasing, and eventually the vehicle couldn’t go over 60 miles/ hour and dropping even lower. That problem created a safety hazard to me and my family since we were driving on the highway and were hundreds of miles away from our destination. After months of not being able to drive the car and having the same problems, I took the vehicle back to the dealer’s service center and had paid them to have some repairs done. However, after a few days, the same issue started again, and had to get it repaired again. The same problems persisted, and after consulting with the technicians, I was told that the dealer had contacted Hyundai and that it is a manufacturing defect and Hyundai needs to change the engine since all the many repairs that had been done but did not solve the known issues. They had reassured me that because I have always kept with regular maintains of my vehicle through the affiliated Hyundai dealers and should have no problems getting the engine replaced. The engine still has not been replaced, all the while I am still paying car insurance on the vehicle. I have bled enough money on a vehicle that I am not be able to drive. I shouldn't have to pay Hyundai close to $5,000 for their defected engine.
ON FRIDAY, 1/31/19, MY SON AS DRIVING HOME FROM WORK AND HIS CHECK ENGINE LIGHT AND OIL INDICATOR LIGHT WENT ON. HE TOOK THE CAR (MY12 HYUNDAI VELOSTER) TO PEP BOYS FOR SERVICE THE FOLLOWING MORNING, SAT. 2/1/20, AND DESCRIBED WHAT HAPPENED. THEY INSPECTED THE CAR AND ADVISED THE OIL SEEMED TO BE BURNING FASTER THAN NORMAL, BUT DID AN OIL CHANGE. THEY ADVISED IF THE WARNING LIGHTS CAME ON AGAIN, TO TAKE IT TO HYUNDAI. THEY ALSO ADVISED WE WOULD NEED TO BRING THE CAR IN FOR OIL CHANGES APPROX. EVERY 3K MILES, RATHER THAN 5-7K MILES. NO CONCERN WAS COMMUNICATED TO KEEP DRIVING THE CAR. THE NEXT DAY, SUNDAY, 2/2/20, HE WAS ENTERING THE 605 FWY (SOUTH) AT FIRESTONE BLVD IN NORWALK, CA AND HE HEARD A RATTLING IN THE ENGINE, THEN SAW BLACK SMOKE COMING FROM THE ENGINE.
