Very recently, the car has been stalling out with no warning, no odd sounds and no obvious reason as to why. I took the car to a well-known, trusted mechanic who was unable to find the cause, as the vehicle presented 0 fault codes. I was informed that I would have to drop the car off for a couple of days so that they could diagnose what the issue could be, and hopefully catch it happening. After doing so, I was then informed that it showed 0 signs of stalling while in their possession. In order to possibly find the issue, the car would have to be kept for more than just a couple of days, which would affect my job and the bill would most definitely be more than I could afford. The symptoms include the following... engine stalls while in idle at a stoplight. Engine stalls while stopping at stop signs. Engine stalls while driving in low speeds. Engine has a rough idle in morning and stalls within first mile of driving the vehicle. This has all been occuring for the past month. Every mechanic I speak to for help agrees it's a mystery issue and that the vehicle would have to be kept for a period of time for diagnostic measures. I'm not sure where else to turn. I use my vehicle daily for work and have never experienced anything like this before. Not only is it a very unsafe and dangerous issue, it literally scares the crap out of me, because when it happens, it's sudden with no warning. Tired of fearing for my life if stalled out in heavy traffic. It usually starts right back up, but at times it takes a minute or a few tries at times. Any assistance in this matter would be greatly appreciated.

Same thing thats happened in 90% of the other complaints... driving, loud knocking sound and engine and power steering died on highway traveling 70mph... you're obviously very aware as I have just sat through and read the complaints all having the same issue with the engine some dying at 58,000 miles which is unheard of. I work at a mechanic shop. This is obviously a manufacturer defect and you refuse to take responsibility and are allowing people to drive around in unsafe cars.. we own 3 Hyundai right now. My grandparents own 4 themsleves... we are all going to sell them as fast as we possibly can and will never buy from your thieving dealerships again. Shame as we've been a Hyundai family for 30 years but you're all about greed now and failing to take responsibility or reimburse all of these families who are out of vehicles during this pandemic truly shows what you're company is all about. Dont buy from Hyundai if you're reading this. They'll recall something with the same issue as yours but claim it's a year behind or ahead of yours and refuse to cover it.. even with 238 complaints absolutely zero responsibility. Just read the complaints yourself.

Was driving my 2012 Santa Fe on rt 565 when the car started making a loud banging sound in the engine and the car just died. I was able to roll the car off to the shoulder before causing an accident. I had the car towed to my house where a mechanic looked at it and informed me the engine was shot and told me about this web site so I could see that there are multiple incidents similar to the one I experienced. I purchased this vehicle new from sussex Hyundai it currently has 108,000 miles I plan on going in tomorrow and speaking with them. With all the engine complaints and scenarios that could have resulted in accidents listed on this web site you would think that NHTSA or Hyundai would implement an engine recall. Hoping the dealer will go to bat for me and contact Hyundai America to fix my engine.

Engine knock that caused engine to fail with less than 95,000 miles despite defaults maintenance.

- Tulsa, OK, USA

The engine went out at 50,000 miles and was replaced and then went out again at 105,000 miles. Same issue. Have contacted Hyundai and they will not do anything to help me. Engine stalled on freeway first time and almost caused a collision, 2nd time on freeway stalled at freeway speed and almost caused another collision.

The vehicle stops running in the road without warning and is unable be restarted. Attempts to charge the battery fail. When taken to be evaluated by the brand dealership, they only change the battery and say that it has been fixed. Within 3-4 weeks, it will shut down in the road again. This has occurred four times, and each time, I take to be serviced and they are unable to reproduce the failing issue. I have reached out to corporate, and have quickly dismissed my case. There was a class action lawsuit in 2016 concerning the exact issues I am experiencing with the vehicle. I would think with this type of documented liability, there would have been a recall on the vehicles or a warning notice dealerships were required to present with the sale. I do not feel comfortable trading the car in as the issue will be transferred to another consumer.

Was driving 65 mph heading South to key largo. The car started vibrating and knocking. The car began to labor, I was able to pull it off the road before it quit completely. The motor died and wouldn't turn over. The battery appeared fine as radio, lights etc., were still working. There was no indication that the car overheated. I popped the, hood, checked my fluids which all seemed to be fine. I did note some oil on the ground and it appeared to have a drip from above. I towed the car to my mechanic. After looking it over, he told me to tow it to the dealer. I'm at just over 119,000 miles; he felt this may be covered. Upon initial diagnosis, the dealer determined that I have a hole in my engine block and it looks like the rod shot out of the block. The manufacturer said they are willing to pick up 60% of the repair which would leave me with a repair bill over the value of the vehicle. My insurance company did an investigation, today, and determined that the damage was mechanical and noted the crankshaft was broken. Mechanical failure is not covered by my insurance. The 2012 Santa Fe with the theta II engines should have been included in the theta II recall regardless of where it was manufactured. I feel for the Hyundai and Kia owners who continue to suffer through these continued engine problems making the car worthless.

My car started to randomly stall without any notice or check engine light. I brought my vehicle to a mechanic and was told all I needed was an oil change. Then one day my car stalled on the highway. The police were notified by another vehicle because they thought my car was on fire. I cannot believe they havent recalled this engine yet. I could have been killed. I sat on the highway in the police car until the tow truck arrived because my car stalled in a bad location and was smoking. My car was towed to the nearest Hyundai dealership and is now going through diagnostic testing. Hyundai manufacturer was directly engaged and they are asking for photos of the engine. How about keeping people safe Hyundai and recall this engine as well and pay for the repairs as the next person this happens to may not make it out of their car to tell their story.... terrible horrifying incident.

Was driving on the highway and heard a loud knocking. Pulled off exit ramp and continued to find a safe place to pull over. After pulling over into a parking lot, the knocking in the engine was much worse. Called for a tow and was towed to a garage. The repair garage stated the motor had spun a main bearing. ( the oil filter was safed). After they did there work I decided to attempt to drive it to a dealer ship. On my there the piston arm broke and went through the side of the block. Now the vehicle is no good.

Driving ca I580 westbound, bright sunny day (2:45pm 9/24/19) in 2012 Santa Fe with 111K miles on it. Going highway speed, without warning (no knocking, no acceleration issues) the engine shut down: Oil, battery and engine lights illuminated. Having no power steering, I muscled the car down the nearest off-ramp (coasting 3/4 mile, I was lucky to be in the far right lane). I had also owned a 2011 sonata that went thru 3 engine failures with symptoms (each time, acceleration issues, gearing hesitation and knocking occurred). With the Santa Fe, no such symptoms, it just shut down after running perfectly. I called roadside assistance and they tried to jump start the car -- no luck. A tow truck took the car to a local Hyundai dealership in dublin, ca. They determined that the crankshaft was frozen causing an engine seizure. I asked if this car was covered under the various engine recalls that have plagued numerous other Hyundai models and they said "no". so it seems I am another victim (4 times over; the sonata was lemon lawed) of Hyundai's engine shoddy manufacturing issues. I am awaiting the Hyundai service department's official report and cost analysis. I will be contacting Hyundai America's customer service tomorrow.

I was driving on the interstate at speed when my 2012 Santa Fe began making a loud rattling sound and losing power. I was able to safely move to the shoulder and stop. The engine then stopped. I was towed to a local garage where a technician inspected the engine. It was found that one cylinder failed and filled up with oil causing a total engine failure. The engine has to be replaced. My vehicle has 101,000 miles on it. Very expensive $6000 engine replacement. Car has run wonderful up till this point.

- Virginia Beach, VA, USA

I was driving on the highway when the engine began to make a noise. It is an engine failure and has to be replaced.

- Newark, DE, USA

While driving straight at highway speed, the engine warning light came on and within 30 seconds the engine completely shut down. The vehicle lost all power and control so abruptly that I was not able to get it out of the traffic lane. After having it towed, two separate mechanics advised that the engine has seized due to lower engine failure, likely a defect in the oil sending unit. The vehicle has 116,000 miles, just being the factory warranty limit, and had had regular documented maintenance and shows no sign of abnormal wear or neglect. I an having a complete and costly engine replacement. I have contacted Hyundai and they refuse to take any responsibility for the defective engine.
