2015 Hyundai Tucson POWER TRAIN,ENGINE

The engine uses about 3 to 4 quarts of oil before a oil change the it will go in limp mode. I have to get it rest and then add oil for the engine to run right. Also transmission don't want to shift 3 to 4 gear it will be 35 mph to 65 before it shifts. When the car goes in limp mode I lose power going up a hill and almost got rear ended. They won't do anything do to its a used car. No lights came on the dash till it acts up.

While driving our 2015 Hyundai Tucson on [XXX] outside of Sanford, Florida, [XXX], at 70mph, the car unexplainably lost all power and my husband had to veer into the right lane while avoiding traffic at high speeds, and pull onto the shoulder until the the car came to rest. This affected his safety, the cars in the right lane, the cars behind him, and his safety on the shoulder. When he tried to restart it, the engine light came on and he immediately drove home. The following day, we took it to our regular mechanic. After inspecting the vehicle, he told us our engine was completely “shot”. We called the Hyundai dealership in Daytona Beach, Florida. The engine light was on, so we paid to have it towed. The dealership called a couple of days later and after INSPECTION, stated the engine was seized, but it was under warranty. Later, we received a call saying it wasn’t under warranty because a KDSD “RECALL” was never completed. We had no idea what he was referring to, as we never received a RECALL notice regarding the KDSD. THERE WAS NEVER A RECALL ON A KSDS SYSTEM. ONLY A SERVICE CAMPAIGN THAT WE WERE NOT INFORMED OF. Therefore, the engine was a total loss and would not be replaced. THERE WAS NEVER A PRIOR INDICATION FROM ANY WARNING LIGHTS OR SYMPTOMS. Upon investigation, I learned that Hyundai was aware of this problem in 2018. Our vehicle was in for regular service on [XXX]. After reading many of the TSB Memos, Their Service Campaign began on [XXX]. We never received notice regarding this campaign. Nonetheless, as our car was in for service IN SEPTEMBER OF 2018, they should have made us aware, and performed the software update then and there. The software only warns the driver that there may be a problem. This update doesn’t improve THE ENGINE which is defective. It is abhorrent to me that they are still putting lives at risk. HYUNDAI NEEDS TO RECALL THIS ENGINE BEFORE SOMEONE GETS KILLED OR IS SERIOUSLY INJURED. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving and there was a knocking noise from the engine and loss of power. I opened the hood and noticed a pulley on the belt that looked loose and had the car towed to the dealership. According to them they know this particular engine Theta model has been an issue for fires and engine failure with components breaking internally but no recalls have been addressed for my VIN number even though there are hundreds of thousands of customers with the same issues and only some recalls have been made. Ultimately leaving the customer with the bill. This is a very dangerous situation and reading hundreds of comments on various sites and these incidents happening in other countries as well with this engine, there should be a huge investigation and something being done about this.

WHILE DRIVING ON INTERSTATE A LACK OF POWER WHEN ACCELERATING WAS NOTED. HIGHEST CAR WOULD TRAVEL WAS AROUND 60 MPH. ENGINE WAS REVVING BUT NO SPEED COULD BE GAINED. HAVE REPEATEDLY HAD THIS ISSUE WHICH IS EXTREMELY DANGEROUS.TOOK IT TO DEALER THEY SAID VEHICLE IS FINE AND THERE ARE NO RECALLS ON VEHICLE. CALLED HYUNDAI TO COMPLAIN AND VOICED THAT MANY OTHER HAVE EXPERIENCED THIS SAME ISSUE. THEY STATED VEHICLE IS NOT UNDER WARRANTY SO THERE IS NOTHING THEY ARE WILLING TO DO AND THAT THE VEHICLE ISN'T CURRENTLY UNDER RECALL.

I WAS TAKING LEFT INTO MY DRIVE, IN FRONT OF ONCOMING TRAFFIC, THE ENGINE SOUNDED LIKE IT WAS REVVING, BUT I HAD ABSOLUTE NO POWER. LUCKILY I GOT ENOUGH POWER EVENTUALLY TO GET INTO THE DRIVEWAY WITHOUT GETTING HIT. I HAVE HAD THIS HAPPEN REPEATEDLY IN THIS CAR. IT HAS BEEN INTO THE DEAL ONCE AND THEY SAID THEY UPDATED THE SOFTWARE BUT IT HAS STARTED HAPPENING AGAIN. THIS IS SO DANGEROUS. I NEVER KNOW EXACTLY WHAT I'M GOING TO GET WHEN I STEP ON THE GAS. THE DUAL ACTION CLUTCH IS AWFUL AND I WAS NOT INFORMED ABOUT IT EVEN HAVING THIS WHEN I BOUGHT IT. OTHERWISE, I WOULD NOT HAVE BOUGHT IT.
