2015 Hyundai Santa Fe: sudden loss of power

Filed Jun 12, 2026 · Engine · TX

I was driving down the road ( a busy Farm to market road) and my car lost power and died. Luckily i got off of the road. I tried to start the car again, but it kept dying. I had my son in law come help me move the car to a friends house so that I could get it to the dealership. It was after hours. I regularly get my oil changed and when my SIL checked the oil there was none on the dipstick. My SIL put oil in the car. My car was coming up on being due for a oil change. I am a single woman close to 50 yrs old and take my car in for maintenance. I then had my car towed to the local dealership to have an assessment done to find out what the issues is. The dealership reported that the timing was off and that bank 1 and 2 of the camshaft needs replaced. There is a known issue with the engine of this car doing the exact same thing my car did. There were no warning lights on to indicate a problem with the car. I inherited the car for my Mother In Law that passed away. She bought the car brand new and had it serviced regularly.

The engine failed due to complete and sudden oil loss. The vehicle is currently at Fremont Hyundai and available for inspection. Safety risk: the engine failed while driving on the highway with children in the vehicle. A check engine light appeared with no prior warning, the vehicle immediately lost power and stalled, requiring an emergency exit and tow. This is a direct collision risk at highway speed. The failure was confirmed by an independent mechanic who found zero oil in the engine and identified it as a known Hyundai defect. The vehicle was then towed to Fremont Hyundai, which is currently conducting diagnostics. The vehicle has been inspected by an independent mechanic and by Fremont Hyundai [XXX] ). No police or insurance involvement. There were NO warning lights, oil pressure alerts, or symptoms of any kind prior to failure. I purchased the vehicle in 2024 and maintained regular oil changes and checkups with receipts. The last oil change was performed a few months before the failure. No mechanic ever flagged low oil. The only warning was a check engine light that appeared seconds before the engine stalled. I have incurred $900 in towing costs as a direct result of this failure. Fremont Hyundai is now requiring me to pay $280 for a diagnostic, followed by $890 for a two-week oil consumption test. They have also stated that if the engine does not pass the initial diagnostic, they cannot help me at all. Given that the engine ran completely dry of oil, it is highly unlikely to pass. This means I am being asked to pay fees for a process the dealership already expects to fail, leaving me with no path to resolution and a car I cannot drive. The 2015 Hyundai Santa Fe is included in a class action lawsuit (Cho et al. v. Hyundai Motor Company) over this exact defect.

2015 Hyundai Santa Fe Limited, 3.3L Lambda II GDI V6, ~102,000 miles. In December 2022, an authorized Hyundai dealer replaced three specific parts under a Hyundai recall/campaign (records requested). On Sunday [DATE] at approximately [TIME] PM, I was driving on [FREEWAY], [STATE], at 55–70 mph at night. With NO prior warning — no warning lights, no chimes, no loss of power buildup, no knocking, no engine protection mode — the engine suddenly and completely died. The failure was instantaneous. There was no limp-home mode and no opportunity to reach the shoulder under engine power. The vehicle lost forward momentum and rolled backward in a live highway travel lane, where it remained stranded until a tow truck recovered it. No injuries. The 12V battery and electrical system remained fully active throughout. The instrument cluster was operational and capable of displaying warnings before the failure. None were displayed. Dashboard warning lights illuminated only seconds AFTER the engine had already died — a post-failure consequence of engine shutdown, not a pre-failure warning. An independent mechanic diagnosed a seized engine due to loss of oil flow. No oil pressure or low-oil light had ever illuminated. The vehicle was then transported to the Hyundai dealer that performed the 2022 service; they promised a diagnostic call and have not provided one or any written diagnostic. This failure mode matches Hyundai TSB 24-EM-003H (15yr/150k extended warranty for 3.3L Lambda II engines in 2013–2019 Santa Fe), the federal safety agency Recall 21V‑727 (acknowledging stall risk at highway speed), and the active class action Burns v. Hyundai Motor Company (C.D. Cal. 2025). Hyundai's KSDS is documented to trigger a blinking MIL, audible chime, and reduced-power Engine Protection Mode upon bearing wear. None of these protective behaviors occurred.

Car was burning lots of engine oil and lost power, dealer said nothing was wrong with it. months later when to limp mode, lacks of power in the highway, dealer said it lost compression on 2 cylinders and that I need a new engine. I ask them if the vehicle has a recall and they said no, all my research said that this type of engine has a recall for me they are looking for any loophole in order not to replace the engine

Sudden loss of engine power in traffic on highway in funeral procession. My safety was put at risk on the highway. The check engine light came on intermittently the previous week. I made six trips to the Hyundai dealer in Plymouth, MA. First told the oil was low when the dipstick was normal. Oil was changed. Check engine light came on as I left the lot. Two more trips computer reset two different ways. Engine does not have normal power going up hill. Another trip to dealer EVAP hose collapsed. Light back on and off. I paid for diagnostic fee $175, oil change then told it was CVV and timing issue with $2817.89 in parts because the tech "saw" the problem. >$3000 estimate for labor. Repair started now told CVV is not the problem metal shavings in oil OCV intake and exhaust valves and needs new engine. The car had $60,000 miles on it and was extremely well maintained. It does not have a warrantee. This is same issue as the Hyundai recall for metal debris left in oil passages of engine crankshaft during manufacture though my model is not covered by the recall. Hyundai declines to help. There is a huge personal safety and fire risk from this defective manufacturing process.

We were on our way home from the children's hospital in Philadelphia for my daughter (4 hours away from home) and my 2015 Santa Fe with the 3.3L motor began to knock. My dad (who is very mechanically inclined) pulled over at a gas station and checked oil and other fluids. It was low, even though I just had oil changed 900 miles before and it was checked before our trip to the hospital. We bought oil and put it in. Knocking was still there but was not as loud. We got back on interstate. Few miles up the road it completely lost power, extreme knocking, no lights on in the dash or any gauges out of normal range. He checked oil and it was completely empty but there was no oil trail or anything. We coasted into a crossover and that's when he saw the connecting rod under the car.

I own a 2015 Hyundai Santa Fe Limited Ultimate and without any warnings or incidents experienced engine failure. The Hyundai dealer told me I need a new engine at the cost of $23,000.00. I know you have received complaints and are investigating these engines. I was driving the car at the time and lost power.

We have had issues with our 2015 Hyundai Santa Fe Limited that culminated in effectively lose of the car. The engine has a knocking, and is leaking coolant now. This started with the car sometimes sort of stuttering when you press the gas, or sometimes sudden lose of power while driving. It now sounds like a rod may. E bad, I’m no expert. Hyundai has said I need a new engine. The car which I bought new in 2015, has 116k miles on it. It has been well kept. I have older Hyundais that still have great engines at much higher mileage. I am registering this complaint, because it seems strange to loose an engine of a well maintained car at 116K miles. I know there are investigations and recalls on the smaller Santa Fe engines. But I suspect there is an issue with the larger 3.3L engine too. I’m registering the complaint so attention can be garnered for the 3.3L engine too. I suspect I’m not the only one with 3.3L engine having an issue. Regards

Vehicle has been consuming oil between oil changes. Recently the ABS, Down hill assist, and traction control lights came on. We took it to the dealer and were advised it was a wheel speed sensor in the passenger rear, but they wanted over $600 so we did not repair. Two days later all the lights went off and we had no issues. A month later I drove to Florida, checked and filled the oil with a little over one quart. On my way back the RPM shot up to close to 6K, the engine light started flashing, oil and battery light came on, and the car lost all power qnd started shuttering. There was a strong burning smell when we pulled over, that may it hard to breathe. As of writing this we were told it sounds like the engine has seized, but they are 5 months out on looking into it.

Husband was driving on interstate in Indianapolis, Indiana on 8/18/2023. Went to pass another vehicle and suddenly lost power. Was able to get pulled over on the shoulder and had car towed to repair shop. Mechanic advised motor seized up, unable to get the engine to even turn over. No warning lights, oil was only a quart low and have always maintained my vehicle. Have taken in for all recalls and regular maintenance. Fortunately, no one was hurt, but he was driving in rush hour traffic, with construction in the area. This could have been a very bad situation. Hyundai needs to do what is right and fix the issue. I now have to buy a new car and really not in a financial situation to do so!

My 2015 Santa Fe V6 AWD engine had 2 pistons seize up while driving. NO warning lights. I bought the Car with approximately 75K Miles and by 85k miles engine lights came on and engine was losing power. Local mechanic spent $2K trying to fix it but could not. Sent to Hyundai dealer where I purchased it. I spent another 2K (they covered about 3K as Hyundai would NOT cover repairs so dealer did). After month without the car, I got it back. 15k miles later (just as car turned over 100k miles) the car engine began making strange noise but no warning lights. Called AAA and thought we could make it 3 miles to repair shop but engine died in traffic. A second engine request from different Hyundai dealer was denied as "out of warrenty". No oil was leaking (and just had it changed!), no sign of issues of any kind, it just blew. Lucky no one was injured and was able to get to side of the road. I feel they issue should have been fixed at 85K and there must be a real piston issue in this vehicle.

During normal driving operations the car lost all power as our daughter and her 2 children were driving down the street. She called us and notified us that the car would barely run and that she had her hazard lights on and had no safe place to pull over. When she arrived back home from a few miles away the motor was making a very loud knocking and tapping noise. I immediately checked the oil in the car which we have changed on a regular basis and very recently and to our disbelief there wasn't a drop of oil on the dipstick. No indicators or warning lights had come on to tell us the oil was low. We immediately called a local Hyundai dealership, and they explained that thousands of people have experienced consumption of oil with no obvious leaks causing catastrophic engine failure in Hyundais. Upon inspection from the dealership, it was determined that the motor had spun rod bearings due to excessive oil consumption. However, we have since discovered that the 2015 Hyundai Santa Fe is pending a class action lawsuit in California and no recall is current for this year and model. This could have caused serious and devastating fatalities to not only our family but others as well. Hyundai has not yet been willing to work with us for a car we purchased a little over a year ago and are still financing. The warranty did not transfer to a 2nd owner and we were not informed of this. Now the car sits at a dealership and I continue to make payments on a useless vehicle. The manufacturer of Hyundai's engine is the same for many models. However, not all models and years have had recalls yet. This puts thousands of people, like us, at risk for serious injuries, fatalities, and devastating financial loss. The public relies on their vehicles for their family's transportation and their jobs. I did my research and searched for this year, make, and model and found nothing that deterred me from finding this vehicle unsafe or unreliable. Hyundai is not in good faith protecting customers.
