I was traveling in Texas with my child on the highway going 65 when my vehicle went into limp mode and immediately started making a noise like a card in a bicycle tire and would not accelerate. After a few seconds the check engine light came on blinking. I managed to make it to an exit and pull into a gas station. I called a tow company and had to wait more than an hour in the heat with my [XXX] for them to reach me. I called the closest dealer which was aslo an hour away and made sure they were aware the vehicle was coming. A family member drove two hours to get us. A service tech texted me that night and told me the car was awaiting a tech. First thing Monday I received another text that a new engine replacement had been approved. It actually took several phone calls and trying to reach anyone to actually find out that the car had code p1326 and had failed the rod bearing test. And I read more about the gdi theta II settlement and reached out to customer care and opened a ticket to be reimbursed for towing. The vehicle had a previous recall completed for the knock sensor. No rental cars were available to me AT ALL. I received a remanufactured short block all said and done in 10 days. My family was left with no car for that time. There were no warning signs on my car-no excessive oil consumption, no other lights or noises. terrified it will occur with the replacement.

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.

As I'm driving on the highway, I hear a strange sound from the engine. I look at the dash but warning lights are on. I start making may way to the right lane to exit the highway, but the car starts to slow. I look at the dash again and the low oil light and check engine light are on. I make my way to the shoulder and the car completely starts running. Shortly after, a tow truck takes the car to a nearby mechanic shop. The next day, the mechanic tells the hyundai tucson threw a rod and the engine is destroyed. The mechanic says he has seen this before. I've found several complaints about the same thing. This is a dangerous issue and it is unfair to consumers. The 2014 hyundai tucson has only 85,602 miles on it.

My wife purchased her 2014 hyundai tucson brand new and we have maintained regular oil changes and kept up with maintenance schedules. Her tucson is at 115k miles and is burning a lot of oil with no leak and no additional white smoke from the tail pipe. Its burning about 2.5 to 3 quarts of oil every 1500 miles (conservatively). I have tried high mileage oils and thicker weights to reduce the burning. I have tried lucas heavy duty oil stabilizer. Nothing seems to keep this vehicle from chugging down oil. My concern is that most of the other complaints were due to the engine seizing due to lack of oil. Do we know why these engines are burning so much pr how we can change that? My hope for this complaint is to help others before they burn up their engines not realizing how fast their engine is burning oil.

My 2014 hyundai tucson's engine burned oil and now the engine is completely destroyed at only 108,000 miles. I researched and found that this year, make and model has the same engine as my wife's recalled 2014 hyundai sonata. Her car is also burning oil and is now going through tests to determine if they need to replace her engine. In the meantime I have a case number with hyundai. Hyundai can't answer why my model hasn't been recalled yet. I looked online and found a private facebook page of other hyundai tucson owners with blown engines. If my car was recalled like my wife's car I would still be under warranty as they extended her to 120,000 miles due to recall. My car is 8000 miles out of the warranty when my engine blew. We're still waiting to hear back from hyundai corporate as to what will happen with my car. Meanwhile still paying a loan on a car I can't drive. Disgusted and furious are just the beginning of how I feel.
