Vehicle was purchased used for my teenage daughter's first vehicle and the vehicle was purchased from a reputable used car dealership with the vehicle having a very good Carfax vehicle history report and appeared to be mechanically sound. After two months of normal use and no mechanical warnings ever appearing, my teenage daughter was driving on the highway at night when the vehicle engine suddenly stopped with vehicle losing all power and being disabled on the highway in a hazardous location that could have caused a serious vehicle accident with my daughter being seriously injured or killed by passing highway motorists due to the sudden engine malfunction. The vehicle was towed to a Hyundai dealership for inspection, and I was advised that the crankshaft was immobilized, and that the vehicle will need a new engine. With no warning lights ever being displayed or any other signs of self-evident mechanical problems, I suspect that this particular model vehicle has a serious engine defect that needs to be investigated to prevent a loss of engine power vehicular accident that could result severe property damage and serious bodily injury to the vehicle operator, passengers, and other motorists. The vehicle is still disabled at a Hyundia dealership and available for inspection.

The car stop running in the middle of the highway. Was taken to the dealership and they sled us to pay close to 700 for an inspection. Since then I have been part of numerous groups that report similar issues with certain types of engines.

The vehicle lost power and started making a knocking noise from the engine. The vehicle would not accelerate at all, then quickly increase in RPMs and throttle forward. The knocking sound increased in intensity and volume. The RPM's continued to jump as did the power and acceleration. No check engine lights ever showed. After about a year of owning the vehicle we noticed it was burning through oil at an alarming rate. At a Hyundai dealership we were told that it was normal for that engine to require oil top offs between oil changes. We had it looked at by a local mechanic and was told it is total engine failure due to an internal component and will require a new engine.

***(NW Indiana)*** 2017 Hyundai Santa Fe Ultimate FWD 3.3L - 64,000mi. Driven to and from work and around town. Purchased used with 31,000mi in July 2020 from Knauz Hyundai. On the afternoon of December 22nd, 2022 I went to accelerate from 35 mph at which point I heard "tick-tick-tick-tick-tick". I had never heard that sound before. I tried the accelerator again and the same "ticking" sound was there. It became progressively louder on the 15 minute ride home but only while accelerating. During this whole episode not once did any warning light come on. I got home and popped the hood to listen to it(I did video record the sound) and to check the oil. The oil was a bit low but I topped it off and then put a code reader on the vehicle. The only thing that came back was a low voltage on the battery. The next morning I started it up and the noise was even louder. After a few minutes the sound subsided a bit, albeit still loud. I was able to drive it to work so that our mechanics could hear it and all three said it sounded like a bearing went bad and that the engine might be a loss. I spoke to another friend that is a mechanic that hosts a local radio show and he said that he had a show recently about how he is seeing A LOT of Hyundai's coming in with the exact same problem. He told me about a recall from 9/19/2017 with the #17V578000. While I am not certain that this pertains to my vehicle, everyone that has read the recall says that can absolutely be the issue. I have tried calling Hyundai Consumer Affairs but sit on hold forever only to be finally disconnected from the call. I am taking it in to Hyundai on January 6th, 2023 for the ABS recall and they said they would charge me $199 to look at this issue. After reading through all of the complaints regarding this problem Hyundai needs to make it right for their "valued" customers.

Car seems to stall on slow turns, then after 2 seconds its back to normal. Dangerous when turning to avoid oncoming traffic. This vehicle belongs to my granddaughter (Britney N. Smith) I'm driving it as it's too dangerous for her. Dealerships have no solution for this problem!

I am a 2017 SantaFe Sport owner. I purchased my Santa Fe in Florida in December 2016 to include all the premium options, including a 10-year powertrain warranty. I believed I was investing in a vehicle that I would have for years to come, at least 10 years. I have always taken my car to be serviced at the Hyundai Service Center and paid for all the recommended services. Earlier this year, I was about to take a long distance trip in my trusted car with my son and elder mother. As I checked my vehicle to make sure it was road ready, to my surprise, it had no engine oil although there was over 1K miles till the next oil change! The oil stick was completely dry. Feeling unsure about my car, I ended up having to make an unnecessary expense and rent a vehicle. After seeing my service advisor at Hyundai, he recommended we start an oil consumption test. After several failed tests, car rental expenses, time away from work, purchase of engine oil and oil funnels, and a recommended Combustion Chamber Cleaning, my car is still consuming the oil with over 4K miles (4 months) till the next oil change. My car was back again at the dealer for the past 3 weeks for another oil consumption test and another submission for an engine replacement. Yet, Hyundai refuses to replace the engine stating my vehicle is operating at standard. I personally don-??t know of a vehicle, not even a race car, that consumes oil at the rate my Hyundai SantaFe is consuming oil. I have spoken with Hyundai, the service manager, and have proof of all of my documentation. It has been a week since I picked up my car from the service center and it consumed all 4 quarts and the oil stick is dry again. I have also done my research and learned this a known problem that have cause people-??s cars to stall while driving in the highway and also causing fires. There are thousands of people worldwide affected by this same issue.

What component or system failed or malfunctioned, and is it available for inspection upon request" The engine failed and started losing power. It is available at the dealership it was towed to. How was your safety or the safety of others put at risk? I was driving with my family and had just accelerated onto the highway onramp when the engine started rattling and started losing power. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer has confirmed the issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others" The dealer technician has looked over the engine to determine the issue and claimed the engine's rod bearing(s) had failed and that they did not see signs of maintenance neglect to have caused it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? At the time, no, there weren't any warning lamps until when the engine problem actually happened and the check engine light came on. There had been a couple check engine lights over the past 2 years where the car went into limp mode temporarily. The first one a dealer couldn't reproduce as the engine light had cleared itself. The second time they replaced a sensor which may have been causing it.

The engine failed and is available for inspection upon request. The failure caused the vehicle to stall dangerously on the interstate and almost crashed. The problem was due to engine bearing (as diagnosed by third party repair shop) and matches a safety recall (17V578000) for Hyundai 2017 Santa Fes. The VIN, however, does not fall under this safety recall. But it should and I wish to dispute. The vehicle now is at the Courtesy Hyundai of Tampa. No warning messages appeared before stalling to my knowledge. This happened 4-5 weeks ago and has been in the shop since. There was a delay in reporting a safety problem because I tried working with the manufacturer directly. There was miscommunication and they submitted a case on my behalf to check the car for warranty but not to investigate the safety recall. Repair invoices yet to be provided. Courtesy Hyundai of Tampa should have more information: 813-356-7576

Cvvt timing malfunction causing over advanced bank 1 shaft to blow

Vehicle: 2017 Hyundai Sante Fe Sport - While driving down the highway, the day before Thanksgiving, 11/23/22, the Sante Fe began to knock and immediately began to decelerate leaving my youngest sister stranded on a dark backroad in NC in the middle of the night! She pulled over into a local church that was thankfully in the area and had to wait alone for a while. This is extremely dangerous as the road she was on was a winding road, 55 mph speed limit, steep shoulders, and the vehicle gave her no warning prior that something was wrong. After getting the car towed to a repairman we got the news that the engine has failed and that the engine rebuild alone is $10,000 (low estimate). This is not the Hyundai that I know and something must be done to rectify this.

Failure of Oil Pressure Switch Assembly resulting in oil leak. Not covered by warranty. Dealer repair resulted in cost of $544.94 to owner. Vehicle mileage: 63591 miles. Appears as wide spread problem with this engine type from Hyundai/Kia.

I was accelerating on the highway and my RMPS shot the whole way up over 7,000 then bottomed out. I lost speed so I pulled over. Another car pulled over to inform me my car was on fire. I turned the car off and the fire went out. The car was towed to Blaise Alexander (dealership) in Altoona, PA. The mechanic reported that a connector rod went through the oil pan, engine block, and brake starter. He kept repeating to me "I've never seen anything like this before". He reached out to Hyundai to ask if they would cover repairs (starting at $13,790). Hyundai said no. I believe this incident was more than mechanical, and is related to the open recall. I attempted twice to have my car repaired under the recall but the dealership "didn't have the part".

I was on my way home from work in the interstate, I started to exit the interstate and my car would not accelerate, and just died. I was going around 45 mph and there was no indication till it happened and then the check engine light came on. I couldn-??t get into Hyundai since they have so many broken cars so I took it to 2 mechanics who both told me the car is immaculate condition and should not have had no oil in it unless there was a malfunction with the engine. Both mechanics told me to get it to Hyundai because my car is doing exactly what the 4 cyl that they are recalling is doing. I made apt and got car in last week. Dealer is telling me that it-??s out of warranty so they won-??t do anything. My daughters car is same year (different model) with same mileage and he-??d engine also went out 2 months later. Something is not right with this brand of vehicles and will cause serious injuries.

On November 14, 2022 at approximately 0800 while traveling 495N in Massachusetts from Cape Cod my 2017 Hyundai Santa Fe with 109,000 miles experienced catastrophic engine failure. I was maintaining a speed of approximately 70 MPH when without waring the 3.3L V6 engine stalled and made loud clunking noises while smoke filled up the cabin of the vehicle causing me to cough and choke, my visibility was also diminished. I was fortunate enough to pull the vehicle to the right side of the highway and did cut someone off because I panicked and could not see almost causing a serious crash. The vehicle was then towed to a Hyundai dealership in Raynham, MA. The service advisors tried helping me with getting a new engine replacement from Hyundai Corporate, Corporate would not honor their demands and now I'm without a vehicle for myself to get to and from work and for my family so they can attend school, doctors appointments and social events.

With no warning lights, no unusual sounds coming from engine (knocking, or otherwise) - complete engine shutoff. Driving on highway at 55-60mph during acceleration. I was able to coast to the side. Unable to restart engine for about 30 minutes. Engine able to restart, then shutoff again a few minutes later at 45mph. There have been reports of unusually high motor oil consumption with the Theta 2 engine. There are no leaks, smells, smoke (from engine or exhaust) however, I must continuously add motor oil and check levels about every 100 miles. Oil level will reduce from max line to almost empty very quickly, maybe 1-3 weeks after refilling. All service maintenance is timely and done at authorized shops (Goodyear and Hyundai dealership). Dealership will perform oil consumption test to determine if eligible for powertrain warranty. Further research shows Hyundai denied many claims related to this issue.

2017 Hyundai Santa Fe rod bearing failure occurred 10/09/22 without warning (no indicator lamp, messages or symptoms). The vehicle is currently at Keyes Hyundai in Van Nuys CA, Hyundai is refusing to cover the repair as the vehicle is over 100k miles. If the engine rod had blown while we were on the freeway this would have likely been fatal. Problem confirmed by Hyundai 11/3/22, the vehicle is available for inspection by NHTSA. Hyundai has a lengthy history of engine problems and my vehicle ought to be covered under this condition. I still owe over $4k on the vehicle and only owned it 5 years. Hyundai Corporate Care representative offered and then retracted coverage, we transported the vehicle with the assumption of coverage. Transcripts of her voicemails are attached. Please help.
