My car stopped running in the middle of the road. I had to slowly pull over and have it towed to the dealership. Upon further inspection, the dealer told me that the engine is dead and to replace it would cost 15K. I have 121K miles on the car and Hyundai's warranty ends at 120K. They refused any coverage and I am expected to cover the expense.

Acquired vehicle in November 2021, with 20,718 miles. I noticed a small knocking noise coming from engine area, but discounted any major problem due to the fact it only had 20k miles. After using the car for two weeks, and researching this engine knock noise, I discovered there is a long history of engine failures due to faulty internal engine components on this type of engine. I took it to the Hyundai dealer to diagnose the problem, and was informed the knock was normal and had past the -??engine noise test-??. They stated there is no open recalls for this vehicle, and that I should go back if the noise increases. I feel this vehicle is now unsafe to drive because the engine has to basically fail, and thus place my family-??s safety at risk and even possibly cause an accident or engine fire, in order for it to be fixed by the dealer. I believe this model year and engine type needs to be investigated and be recalled, as many other vehicles with this same exact engine have had this same problem, resulting in total engine failures, near accidents and even fires. I have read there are even lawsuits on this dangerous engine defect.

I was drying my 2014 Hyundai Tucson 12/27 and the engine began knocking and the speed dramatically decreased. Now, the engine no longer works at all. I took it to the hyundai dealer and they refused to fix because it is not currently in a vehicle recall campaign (although it should be). I am also filing a complaint with the nhtsa today, which currently shows 49 similar complaints for this exact year and model.

Engine started knocking and vehicle went into limp mode as my daughter left highway for her exit. When Hyundai attempted to replace engine, discovered 4WD transfer case seized into transmission preventing removal of engine, replaced engine, transmission, and transfer case. This is the same engine in the Santa Fe, and sonata which was recalled. Hyundai is still refusing to extend the recall to the Tucson too. So owners are not entitled to the extension on the extended warranty. Due to them not wanting anybody to know about this defect in the motors that the Tucson share with their other models. The government should of stepped up and made Hyundai honor the extension to include the Tucson model too. For all Tucson owners are left in the cold with a vehicle worth [xxx] since they are still having more problems with this 2.4L motor.

My fianc was on his way to work when all of a sudden the car starts to stall. It put him in a very dangerous situation as he has just crossed over a bridge. This could have cause a car accident. After this happened the oil pressure light comes on and also the check engine light, and the engine starts making knocking noise. We have kept up with oil changes and maintenance, so why this happened is just unexplainable to us. Also our car only has 65,893 miles on it. So just how can this happen? so we brought it to multiple dealerships and they said it needs a new engine, something you definitely never want to hear.
