What 235 owners told NHTSA about the 2016 Hyundai Santa Fe Hybrid Hev

We were driving through our neighborhood at about 25 mph and we heard a slight knocking noise and then the engine shut off, no warnings or lights, just engine failure. The electronics worked, but car wouldn’t start. Had it towed to a local mechanic where he said the engine is seized. We were thankful this happened at a low speed in a safe place, can’t imagine how awful it would have been if we’d been going 75 mph down the 4 lane interstate. Of note, we have always kept the vehicle current on oil changes/maintenance. Prior to this, the car drove great! Never had any issues that would point to impending trouble.

Was driving on a 5 hour car ride at 5pm on August 16th and was going up a hill, the vehicle quickly lost all power and the engine light lit. I was able to pull the car to the side of the road with the momentum that the car already had, but was not able to get the car to a safe space (its about 6 inches from an exit ramp lane), as the car would not drive. Once I got the car to the side of the road, I checked the engine and did not see any excessive heating or anything out of the ordinary. I tried to restart the car and the check engine light is lit and the battery system for the car turns on but the car will not start or try to turn over the engine. The car is currently sitting on the side of the road. My wife and my dog were in the car and we had to quickly move to a safer place away from the 70 MPH traffic. Calling a tow truck tomorrow to take it to a dealership. It was a little scary that the engine power cut out like that without giving an engine light notice in advance or giving time for me to navigate to a more safe space to park it.

The door on the drivers side does not lock. It appears that something came out of place causing the door to remain unlocked even with the use of the fab. The car is not drivable because the door swings open. It has happened in a few occasions where the lock appears to get stuck but was always fixable. On this occasion it was not. Thankfully, I was parked when this occurred.

Abs system is randomly locking up calipers causing a dangerous speed wobble. Dealership can't re create so won't diagnose. Have had to replace all brake calipers and components were near new but ruined because of abs applying brakes when unnecessary. Vehicle is very unsafe to drive, pulled hard to left at one point veering me into oncoming traffic. Independent mechanic has made caliper release by manually releasing abs system. Same results were not found by releasing pressure at master cylinder making abs the obvious culprit. No warning lights but I just replaced two cracked rotors on rear at 130k miles. That should not happen. Has caused hub readings of 270 on three different tires at 3 different times. Santa fe has recall on this system for every year but mine, very curious as to why not. If this was not a dealership only part , it might not be such a big issue, but being it is main source of stopping a 4000 lb vehicle, I have concerns. Hyundai dealership was very condescending and of little to no help. I have an Independent are certified mechanic who is happy to talk with you if needed. Please help, as of right now am.making payments on an unsafe vehicle with not much hope of it being fixed.

Vehicle was driven on a highway approximately 45-50 mph when a loud knocking sound occured. The vehicle began to shake erratically and a bunch of lights displayed. I pulled over at a safety point and turned the vehicle off to inspect it. A large amount of smoke poured from under the hood. The vehicle sat for about 45 minutes to cool down before I attempted to start it again. The engine continued to make a loud knocking sound and kept stalling. At the given time of engine failure, I was driving on a fairly busy highway with my two toddlers where we were forced in a dangerous situation to be struck by a vehicle. Hours later, I went back to start the vehicle where I was able to get it started and drive approximately 15 mph to a safer area for the vehicle to be parked. The vehicle has been at the Hyundai Bowser Chippewa location in Beaver Falls, PA. I was denied for any assistance through Hyundai and the BBB-Hyundai due to 3 open recalls, mainly the engine knock system not being updated. All issues and diagnostics were conducted at the dealership where the vehicle is being stored. No police report has been filed, nor was an insurance claim conducted. No lights or warnings came about until the engine started to noticably fail. I didn't receive any notifications from Hyundai regarding recalls, and nothing is displayed on the NHTSA site.

On July 3, 2024 my husband was driving our 2016 Santa Fe with a v6 engine on a highway. He was coasting down a hill going approximately 65mph when he heard a loud bang and saw something shoot off to the left of the vehicle. When he tried to brake, he realized the car had shut off and he did not have automatic steering or breaks. He managed to get the car safely pulled off the highway by using all his weight to stand on the brakes and turn the car. The car did not start up again. When we got the car towed home, we were looked under the hood and found that the engine had shot a rod. We found pieces of the engine/rod along the bottom of the engine bay. We called local mechanics as well as Hyundai service center and got quotes for repair ranging from $9-20k. The car was purchased in July of 2023, the engine had 97k miles on it, with 8k miles being put on from July 2023-July 2024. The vehicle passed PA state inspection on June 2, 2024 by the dealership’s service center.

The vehicle began making a knocking sound upon starting. I contacted the local dealership for a service appointment and learned that they were out a couple of months on their appointment schedule. A day or two later, my vehicle shut off while driving, I was fortunate to have enough momentum to pull of the road safely. Upon having it towed to a local mechanic, I learned that the engine seized and needed to be replaced. I contacted Hyundai and they have scheduled me for an appointment next week. Keeping my fingers crossed they will do right by me since I have always had the vehicle serviced at their Hyundai dealership. The car has approximately 118,300 miles on it.

The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 94,000. The VIN was not available.

Car started making noise after the check engine light came on. Check engine light was on for just a few days then by the third/fourth day the car starting making noise, turned off on me a few times then just died. We replaced a few sensors and the battery and starter. Two mechanics have told me the engine is locked and needs to be replaced.

Was driving on the highway going about 65mph when the engine just lost power. Pressing the accelerator and there was nothing happening. Had the car towed home. And then to a mechanic who told me the rod was bent. I’ve always kept up on oil changes and maintenance. I just had an oil change less than a month prior. There were no warning signs leading up to this incident.

On 5/15, I was entering the highway when the vehicle refused to accelerate. I pushed the gas pedal all the way to the floor, and the vehicle did not respond. I checked to see if it had stalled, but the engine was still running. I watched the rpm meter as I pushed the accelerator, and noticed that the rpm’s stayed at 1.5 the entire time. I pulled over to the shoulder and turned off the vehicle as I was afraid of causing an accident as I was not at highway speed at the time. I turned the vehicle back on and when it was safe, attempted to reenter the highway. The vehicle responded appropriately. The check engine light had come on 2 days prior to this (5/13) and I was in the process of trying to make an appointment to get it fixed. My husband ran the engine code (P0014 and P0024). The check engine light had turned off upon restarting the vehicle but turned back on about 3 minutes after resuming driving. I took the vehicle to a mechanic to have it looked at, and they noticed that the engine had lost 4 quarts of oil. There had been no oil leakage noted at any time. They added 3 quarts of oil to the engine and noticed that the knocking sounds remained. Their determination was that the car was pretty much totaled. There were no indicator lights on the dashboard to notify me that there was low oil at any time. The only indicator that showed was the check engine light 2 days before.

Around three weeks ago, we start listening to a knocking noise in the engine. As soon as we heard this noise, we took it to a mechanic near our home and the mechanic told us that there was an internal problem with the engine and we needed to take it to an official Hyundai dealership to solve this problem. Moreover, they told me this is a common problem in Hyundai's cars and the dealership would do it for free. When I took it to the dealership, they told me that I had to replace the chain timing, tensioners, CVV, and many other stuff needed (I'm sending the receipt attached, see "car report 2024.pdf"). It was going to take 10 hours of work. Importantly, this was not covered by the Hyundai warranty or recalls. I bought the car 3 years ago, and both the previous owner and I did the year service to the car. I'm sending all the receipts and CARFAX of the services. Best regards, [XXX] .

6 months ago my rod bearing broke in my engine, and I needed a new engine. From the engine recall. With a broken rod bearing you get an oil consumption problem. Oil consumption ruing your cat converter. But they aren’t telling anyone that. 6,000 miles after my new engine, my catalac converter broke. These cars are dangerous. They’re not telling anyone that this is the next problem. They just put you back on the road. Not to mention bad for the environment!

Engine light came on while driving and vehicle began to malfunction with bogging and little power to move the vehicle properly. Vehicle was towed to Hyundai dealership for diagnostics. Determining that there is rod bearing failure in the motor. Contacted Hyundai corporate who denied warranty claim citing I did not properly maintain the vehicle per owners manual although they were provided with records of proper maintenance, however it was disregarded by Hyundai warranty people as proper maintenance. I have contacted BBB and PA Attorney General for assistance but to no avail. There are countless others with the same exact issues where Hyundai Motor America is denying warranty claims for identical mechanical motor issues.

-Premature complete engine failure, at approximately 72,000 miles. -Luckily, was able to get vehicle to manufacturer dealership prior to complete immobilization of vehicle while on the road. -Engine “bearing” failure per dealership. Requires complete engine assembly for repair. Complete engine assembly no longer available, only manufactured for 6 years, and requires 150+ parts to be assembled at dealership for “short block”. -Dealer serviced maintenance documented at correct intervals. -Incident occurred without any warning lights, first and only symptom was a loud knock from the engine that increased in volume and and speed with increasing RPMs. -Vehicle remains at dealership, pending resolution. -Dealership states no active manufacturer recall on issue with this particular engine, but is aware of many other similar complaints and engine failure with this model of engine, 3.3L Lamba II GDI engine. Desire to add my complaint to any others as this poses a safety risk to other owners. Online research reveals an active investigation by the NHSTA and a class-action suit regarding this issue. Please help, and contact me if you have any questions or concerns. Thank you.

My car started accelerating on its own, out of nowhere. There were no prior indications. No prior damage. It began accelerating on its own. After shutting the vehicle off and turning it back on, the issue has persisted. Anytime it is in drive or reverse, it accelerates at an extreme rate. It also disabled the brake, when the acceleration began.
