Engine light started blinking and I could not accelerate anymore. After driving home, I figured out it was showing P1326 error. It didn't allow me to go above 60 mph or 2000 rpm. Further digging into the issue I figured out that this was a common issue with hyundai and kia cars, but there was no recall for my car. I took the car to dealship as it was still under warranty and they only updated ECU for knock sensor. No other repairs where done saying that there was no solution to the issue. Other cars get their engines replaced and get lifetime warranty. I got no repairs or extended warranty.

Iba conduciendo mi vehículo por carretera y de momento se apago. Vehículo no quiere volver a prender. Vinieron del seguro, verificaron el vehículo y encontraron todo en perfecto orden, poleas, aceite, transmisión. Solo encontraron el motor que no corre. Adicional me indican que ya el vehículo no tiene garantía por ser yo segunda dueña, lo cual nunca me explicaron y lo peor de todo es que me quedan solamente 5 pagos. Nadie se quiere responsabilizar de dicha situación.

56k ish miles on my car, 2nd owner. Oil pressure light flickered on and off about.5 miles from home after 20 mile highway drive, steady on when pulled into driveway. Turned off car immediately. Have noticed excessive oil consumption but check and top off frequently. Topped off less than 200 miles prior. About halfway or less since last oil change mileage wise from what I recall. Checked oil and about halfway between bottom and top markers on dipstick. Took to dealer Monday (.8 miles from home). Oil light did not come back on. Dropped off. Dealer said light came on shortly after driving. Said problem could be caused by -??aftermarket-?? oil filter aka not a OEM filter. Said would do oil & filter change to see if resolved. Yesterday (Thursday) said oil & filter change complete & oil light not on. Reiterated previously mentioned concern of engine failure and potential accident. Service advisor said hyundai will not entertain engine replacement unless oil consumption gets documented. Oil consumption test to be completed after 1000 miles or until low oil levels noticed/oil pressure light illuminates. Will pick up tomorrow to see what happens. Engine is covered under newly extended warranty if failure occurs. Service advisor says nothing else was checked internally, spark plugs, etc. as this would incur engine being taken apart and extra charges prior to hyundai -??entertains-?? covering engine replacement etc. Although no failure has occurred yet I-??m worried something will and it will result in something potentially catastrophic for not only the engine/car but myself.

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.
