2012 Hyundai Tucson: engine failure

Filed Aug 18, 2026 · Engine · NY

I bought my 2012 Hyundai Tucson from a used car dealership back in November of 2024 . When I bought the vehicle it only had 55,000 miles on it and came with a 2 year unlimited mile warranty on the drive train and a full Carfax history in which everything came back clean , regular oil changes with synthetic oil every 4,000 miles and for my warranty through the used car dealership requirements I have continued to honor the every 4,000 mile oil change with synthetic oil every time . I have my Carfax that shows that my vehicle was brought to a certified Hyundai dealership back in 2019 for maintenance and the dealership never applied the required KSDS software update to extend my warranty. Flash forward to 8/06/2026 my vehicle with only 94,000 miles on it is sitting at a Hyundai dealership with the engine blown . I filed a claim with Hyundai and of course they denied it . I filed a complaint with corporate because it was at a certified Hyundai dealership back in 2019 they have had the updated KSDS software available at the time knew that it was a requirement for the extended warranty and didn't add the software update to my vehicle. I have asked for a good faith gesture and was also denied . I'm on a fixed income with a disabled husband and a disabled son . I still owe a considerable amount on the vehicle since I've only owned it for 1 year 7 months . The used car dealership I bought it from will only cover up to $2,900.00 of the repairs and the new engine is costing me $7,601.01 . Leaving me with a remaining bill of $4,701.01 . While that's pennies to them to me that's 4 months rent and my family not eating for 4 months . . I even tried to work with them to split the cost and again was denied . They know their 2.4 theta engine is inferior and was court ordered to extend their warranty. I was informed when I brought it to the dealership that is fixing which is also a certified Hyundai dealership that it has 4 open recalls attached to my vehicle that needed to be fixed

Engine started knocking luckily I was right by my mechanics place. They said needs new engine. Not to drive as a rod might go right through the engine. Only 98000 miles on it. Maintenance always done on time.

I was driving on the road way and the entire engine seized. I had to glide over to the side of the roadway and call AAA. I called Route 1 Hyundai, where the car was originally bought, 7324126502 brand new in 2012. and they told me no warranty on vehical. I had vehical towed to a mechanic in Hightstown, NJ and they told me to check that he just put in a new engine in the same car covered under a class action lawsuit for the same problem. I called the dealership service manager William, and they told me that they are not willing to do anything. I am the original owner and what happened was very dangerous and I could have lost my life! I usually drive on highway going 65mph. This could have been a catastrophe with no warning!!

The contact owns a 2012 Hyundai Tucson. The contact stated that while driving 60 MPH, the vehicle stalled and entered into Limp Mode without warning. Due to the failure, the vehicle was towed to a dealer where it was diagnosed with engine failure. The manufacturer was notified of the failure but offered no assistance. Upon investigation, the contact discovered the federal safety agency Campaign Number: 19V063000 (Engine and Engine Cooling) which she linked to the failure. The vehicle was not repaired. The failure mileage was approximately 141,000.

2012 HYUNDAI TUCSON Bought it used, 1 prior owner ~50K, very clean. Since is VERY well maintained (incl. oil changes). Periodic engine light off & on for no reason. NO other probs, no oil leaks EVER. All recalls done. Dealership checked 11/2021 when doing recall, didn't document, it's "a short in wiring", "expensive to fix" & blamed "not tightening gas cap"?! THEN...On freeway with no warning light, a loud "bang" noise heard, vehicle began shaking. Initially felt like flat tire, barely able to control, lost power but able to steer off highway, engine died. VERY, VERY dangerous situation in heavy traffic. During tow to dealership, found # to national recall center who assigned a case number & was told "it's being escalated nationally..a corporate case worker (CW) will call in 3-5 days". Told "tell dealership to give loaner car". No loaners b/c LONG waiting list. Corporate requested multiple exams & photos from dealership in search of "engine sludge" (shift blame technique "poor maintenance") none was found. Engine pictures pristine (per dealership) "like a new engine". Corporate even requested 1st owner records!? Diagnosis:"catastrophic engine failure" due to bearing failure, estimate ~$7K+ for new engine. Corporate offer: 80% of engine replacement cost w/parts warranty (1 yr/12K), no loaner car unless delay due to backorder. Owner gets to counter offer or discuss w/ CW whose role (apparently)is to negotiate w/owner. 3 wks, never rec'd call from anyone. Hrs, days, wks spent chasing elusive CW. "Cust. Care" answers "hello, what's VIN & mileage?". Forced to repeat same story over & over, finally learned CW out on PTO, no one reassigned (someone slipped w/ "we are SOO busy here"). Finally reached CW. Call #1: nice guy. Call #2: lied, blamed dealership, mean, shaming, told to quit calling, wasting HIS time. Take it or leave it on 80/20 deal to replace w/another Theta II (aka we never fixed our prob) engine. NEVER BUY HYUNDAI! SOMEONE COULD'VE DIED.

My 2012 Tucson engine, with 62,000 miles, locked up on 09/22/21 while I was on a trip, without warning & no check engine light came on. Luckily, I was able to coast to the small shoulder. It suddenly seized on a stretch of I15 in the mountains of the Mohave Desert. The engine completely stopped so suddenly that I was lucky I was able to coast to the shoulder. The shoulder was very narrow, so I was barely off a very busy highway, at night. The breakdown happened just before midnight. I was stuck on the side of the road as cars and trucks were flying by us, with little room to avoid hitting us. It took 4 hours to find someone who would tow my car. I was towed to Midas shop at a cost of $800. The Midas shop confirmed that my engine had seized, was full of oil, and no explanation for the engine seizing could be found. The only option was to replace the engine. I wanted a new one, but they could not find one. They found a "used" one from a 2012 Tucson, supposedly with 40,000 miles on it. The mechanic had to go to Huntington Beach to pick it up. He was amazed at the cost of the engine (much higher than they had paid for any other used engine). Ultimately the replacement cost $12,118.41. When I picked up my car on 10/15/21 I headed home to San Diego (170 miles). After approx 100 miles, the transmission suddenly stopped shifting into any gear. It would not come out of neutral. I was in a lane close enough to the shoulder to coast just far enough to get a few inches off the highway. Because it was a Friday evening, there were no auto shops open. I had no choice but to have the car towed to my house (70 miles) at a cost of $500. A local transmission shop diagnosed my transmission problem. It was due to failure of the part that pumps fluid into the transmission. Yet another problem that shouldn’t occur in a car with only 61,000 miles on it. The cost of the repair was $4,200. The failure of those parts put me in 2 very dangerous situations and cost me $20,000.

Air conditioning system was just replaced for $2000. A week later, car to a dealership for a recall. Two and a half weeks later, while driving, engine lights came on, hard to accelerate, then rattling noise from engine. My son was on way back to college and on a rural road with not too much traffic. He pulled over and was not able to restart car. Had to be towed to nearest town (between home and his school, about 1 1/2 hours from each). The repair shop said total engine failure. They investigated and not able to find a rebuilt engine because engine has too many problems and a used engine would be $8000 to install and would likely have same defect. The car only has 96,000 miles. We bought used, from a Hyundai dealership, with a good CarFax report. It was a safety problem because he could have been devastating if he was on a busy highway. Unfortunately, it happened in a scarcely populated area and he was stranded while it was getting dark waiting for the tow truck. No warning lights until time of engine breakdown. Car had just been seen at a service station and car dealership just days before breakdown. We cannot take chance of investing that much money into a car that would have same problem. Had to have car sold for scrap.

My vehicle has stalled (died) several times on me in the last several months. This happens when I am pulling into traffic or stopping at a light, etc. and is a serious problem because it could cause me to be hit. I took the car to my licensed mechanic and he said there was metal in the variable timing hub...he put the new part on it and then changed the oil and took it for a test drive. On return it was rechecked and found to be full of metal shavings again. He stated I would need new engine because mine was falling apart. He checked for recalls and found that this problem was a recall on the Santa Fe and the Sonata but not for my Tuscon...this does not make sense as these vehicles basically have the same or similar engines. Check engine light and oil light came on and stayed on. I was advised by my mechanic to contact you with this problem. I believe Tuscons should be added to the recall list before lives are lost. I believe my car should be repaired by the dealership..I would appreciate any help you can give me on this
