2018 HYUNDAI TUCSON Complaints

The contact owns a 2018 Hyundai Tucson. The contact stated while driving 75 MPH, the vehicle shut off with the check engine, oil, and additional unknown warning lights illuminated. The contact called his brother for a jumpstart, but the vehicle failed to restart. The vehicle was towed to a friend's residence where his brother inspected the vehicle and discovered a hole in the engine block. The vehicle was then towed to the contact's residence. The dealer and the manufacturer were notified of the failure. The vehicle was not repaired. The failure mileage was approximately 123,400.

i was driving on the freeway on Nov 22, 2022 when without warning my car went into limp mode. the engine warning light flashed. this puts the driver (and any passengers) at great risk, as the engine is severely limited in its power output. the car will move, but very slowly and acceleration is weak to non-existent. at highway speeds, this situation could have also impacted anyone behind me who came upon my limp vehicle and could not react in time to my slow speed. it has 60,250 miles on it. i drove home, had an initial diagnosis at a local auto repair shop as follows, "removed the (spark) plug and it is badly damaged with oil in cylinder indicating an internal engine problem". i had the car towed on Dec 7, 2022 to the dealer where i purchased the vehicle. the dealer could not look at the vehicle until Feb 17, 2023 when they diagnosed a burnt valve and the engine would have to be replaced. on Feb 21, 2023 i was told that the replacement was awaiting approval and should only take a day or two. it took until May 19, 2023 to approve the engine replacement under warranty. as of this writing (July15, 2023), i am still waiting my turn at the dealership for the engine to be replaced. it appears that i am not alone in this situation of Hyundai/Kia producing bad engines that prematurely fail and then have to fight for a warranty replacement. i have been almost 8 months without my vehicle.

Tucson 2.0L hesitation at acceleration particularly from a rolling stop: This intermittent problem was checked initially by Marhofer Hyundai in Cuyahoga Falls Ohio, their findings were negative. We then took it to Great Lakes Hyundai in Streetsboro and they said they were aware of the problem and reset the computer, but it did not resolve the problem. This problem has put my family in harm's way many times, making a turn from a rolling stop the car lags into ongoing traffic. Our last visit to dealership we were told car was out of warranty 19,000 miles but the problem was never fixed. This vehicle was a certified pre-owned and have an extended warranty. I have attached a technical service bulletin.

Paint on the bonnet started peeling and flaking off. You can easily slide your finger on the edges of the paint and it will peel right off.

i received a letter in the mail stating the nock sensor has been replaced i dont know howlong ago but my 2018 tucan is stuck in false sage mode saying the nock senor was bad! if it is a on going issue and there is has been a recall on the part why does it show no recalls for my mode car?

These people have sold me a car that is burning oil and they refuse to honor their settlement made by a class action lawsuit against them to replace the motors that are in fact burning oil. At first they told me that they would seal the oil and for me to drive 1000 miles and return to them so that they can determine if the car was leaking or burning oil. Upon return they did in fact say that it was not leaking and that it was burning oil but it was "not burning as much oil as it should in order to replace the engine". In what world should a car burn oil? This car is too dangerous to drive, the other day the engine shut down as I was driving it on I75 which put my life in danger due to its lack of oil. I have reached out to corporate and unfortunately no resolution. Should I wait until I get into an accident or the engine completely burns down as I am driving it for it to satisfy their requirements to replace the engine?

I have only owned the car for 1 month. I had gotten an oil/filter change and a new oil pressure sensor at ~80,100 miles. I had requested the oil sensor be changed because it would flicker on and off when the car was idling/low RPMs once it had heated up fully. This had fixed that issue seemingly. At ~80,700 miles the car had started riding a bit "rough", especially at higher speeds, so I decided to have a look under the hood. I was terrified to see that my dipstick was bone dry. There was never any evidence of any noticeable leak underneath the car on the driveway nor any evidence of blue smoke coming out of the exhaust. After some research (Hyundai corporate was telling me over the phone multiple times that there was no known issues with my specific car/engine) I was appalled to see I was essentially lied to. I found multiple official TSBs, NHTSA notices, and hundreds if not thousands of other customers noting the exact same experience. I had tried to take it to Hyundai for the oil consumption tests laid out in multiple TSBs but I was denied "due to the original warranty expiring". To my knowledge this exact issue has caused Hyundai and Kia to extend to 150k miles for all owners. This is my only mode of transportation and I am so worried my car will stall/seize/catch fire on the highway. This is beyond unsafe and unacceptable but I assume I may have to wait until the final litigation hearing in September for official recalls to be issued. If my car makes it that long.

In the last 3 months I have had my vehicle go into Limp Mode due to a faulty engine. All 3 times while I was on the highway and I was almost seriously injured due to traffic. Ever since I got the Knock Sensor update, I have had nothing but problems. I have had a new catalytic convertor, new spark plugs, oil change, air filter and fuel injector replaced in Dec 2022. The spark plugs are dripping in oil only after 8,000 miles. All of those parts have now failed and I am burning oil at an increased rate. I have contacted Hyundai multiple times and have had case files opened and I have not got any resolution or help. I have spent close to $6,000 on repairs and rental cars and there has still not been any resolution. My engine needs to be replaced due to the recall but no one is helping. I have attached all of the paperwork that has been done.

Three months after I bought my 2018 Hyundai Tucson it started having engine problems. It has went into limp mode multiple times and has been to the shop several times to have it fixed. The knock sensor has been replaced twice by two different Hyundai dealerships. The engine is losing oil rapidly and has to be replaced every few weeks. It has been advised by both Hyundai dealerships that a new engine is required at this point but Hyundai corporation themselves won’t allow the engine repair. This type of car and engine are known for engine replacements around this exact type of engine and amount of mileage on the vehicle. My safety and my sons safety is in jeopardy every time we get in this vehicle as it can go back into limp mode at any given time and if we are driving and it just stalls we are liable to get into an accident. I have to keep taking the vehicle to the shop to have oil replaced and a temporary fix put on it until it just blows as they put it. They are also unable to advise where all the oil keeps going. I shouldn’t be liable for a new engine and it should be replaced by the Hyundai corporation as this happened very shortly after I bought the vehicle, I can be in potential danger when driving, it is a known issue with this type of vehicle and engine, multiple Hyundai dealerships have advised it falls within engine replacement guidelines. I need Hyundai to be responsible for repairing my engine! I have all receipts and documentation from every repair that has been done and every time the vehicle has been taken in.

EXCESSIVE OIL CONSUMPTION! Vehicle has less than 60k and I have to check and put oil in about every 1,000 miles. Engine light comes on and this is how I know to check the oil. This is ridiculous and should not be happening. I change my oil as directed at every 5,000 miles and at least 2-3 times before next oil change I am adding more oil. WHY AM I BURNING SO MUCH OIL? No oil is leaking that I can see...
