2017 HYUNDAI SANTA FE SPORT Complaints

Oil consumption problem.hyundai company denied my request for repair all I have all documents.

My 2017 Hyundai Santa Fe had a new engine installed at the dealership, Fred Beans Hyundai Flemington, NJ. I picked it up on [XXX] on [XXX] (and after 134 miles) my car's check engine light came on. I rerouted to dealership about 8 miles. Sitting outside service bay, I smelled smoke and then saw smoke coming out of vents. I then jumped out of car and the car became engulfed in flames and subsequently exploded. The day I picked it up, I pointed out to the service manager that they had not reattached everything to the car properly, sloppy workmanship. Best guess is that they did not attach a valve correctly. Miracle no one was injured or killed! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated on the instrument panel. The contact later added 2 quarts of oil to the engine; however, not too long after adding the oil, the contact checked the dipstick, and the oil had been consumed. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was taken to the dealer to be serviced and the contact was informed that the engine oil was abnormally low. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 98,000.

Excessive Oil Consumption caused the PCV Sensor/Actuator (Exhaust Camshaft Timing Oil Control Valve) to fail. While the vehicle is still operable, the failure causes engine timing to change resulting unpredictable losses in power during acceleration, excessive fuel consumption, and incomplete combustion passing through the Catalytic Convertor posing a risk for future component failure. In the four months that the vehicle is operating in this condition, with its check engine light on, I have had two near collisions while attempting to merge into roundabouts and freeway entry. Fortunately, both were avoided. I no longer attempt freeway entry during rush hour. Two independent service repair shops did a computer diagnostic test and confirmed the problem with the PCV components. They suggested that the excessive oil condition be corrected first. Otherwise, any replacement components will continue to fail. Excessive oil consumption appears to be a chronic problem in the Hyundai 2.4 L engine. The engine and drivetrain is covered under a 10 year or 100,000 warranty. A year earlier the dealership performed a controlled test when the vehicle only had 60,941 miles, where the initial oil loss was 2.5 quarts per 1,000 miles. An Oil Chamber Combustion Clean, where solvents are used to remove excess carbon was performed. It temporarily reduced the oil consumption to .7 quarts per 1,000 miles. This is still requiring a replacement of about 2 Quarts of oil between routine oil changes in a 5 quart system. The dealership indicated that it passed. About 3 months later the oil consumption increased to 1.0 Quart per 1,000 miles and 8 months later the PCV components failed. If the dealership did the right thing and repaired the engine to eliminate oil consumption, everything would have been fine. I am still trying to get the dealership and Hyundai to honor their warranty. for excess oil consumption. With it the PCV components are also replaced and all is good.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated while driving at an undisclosed speed, the oil pressure and the check engine warning light illuminated. The vehicle lost motive power and the steering wheel seized. The vehicle was started; however, the vehicle failed to start as intended. The contact stated that the vehicle was stuck in the middle of the road. The vehicle was towed to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The dealer was made aware of the failure. The manufacturer was made aware of the failure and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 84,000.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while her husband was driving approximately 65 MPH, he heard an abnormal banging sound coming from the vehicle. The contact stated that the sunroof glass had shattered. The contact stated that the sunroof was not impacted by an object to have shattered. The contact stated that her husband had not noticed any warning lights being illuminated. Additionally, the contact stated there were multiple electrical failures with the vehicle. The contact stated that the cruise control was not functioning, and the tailgate was opening independently. The contact stated that the electrical failures were constant. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that there were no electrical failures found, and a new sunroof glass was ordered. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 53,000.

On December 28th, 2024 I was driving my SUV on the highway at highway speeds. I bought the suv from a Manchester Acura dealer on November 9, 2024. I am the second owner. While driving, the check engine light came on. I was able to complete my drive, but the car idled very rough. After getting the car home, my father checked the oil. It did not register on the dip stick. He put in about two quarts of oil. The check engine code was P0302, which is misfire in cylinder two. He proactively changed the spark plugs since the car had 92,000 miles on it. After changing the plugs, the code did not clear and the engine continued to idle rough. He did a compression test and confirmed that cylinder two had less than 50psi compression vs the other 3 cylinders which were at 170 psi. He also removed and inspected the new plugs after running the engine and cylinder 2 plug was already dark and oily whereas the other plugs were in as new condition. I opened a case with Hyundai Care America. They instructed me to take the suv to a Hyundai dealer for diagnosis. The verbal report of that diagnosis was burnt valves on cylinder two. The dealer stated that HCA would not cover a repair or engine replacement. Hyundai forums and NHSTA complaints are numerous around high oil consumption and burnt valves on Theta II engines. Hyundai needs to be held accountable.

My Engine malfunctioned while driving on the interstate at 70 mph. There were no lights that came on no notice just stopped excelerating. Thankfully after exiting the interstate I was able to get to a gas station safely and that is where the vehicle died altogether and would not start again. My husband and I checked the oil at that time and there was absolutely no oil in the engine. The worse part was that my husband had just put 3 quarts of oil in the engine on Sunday and this all happened on Friday of the same week. I work from home and had only traveled 300 miles that week total, so there was no reason for this to have happen. I had it towed to the car shop and they informed me that Cylinder 1 and 4 are not getting any compression at all. I just had the oil changed in this and am very good about keeping up on maintenance in my car. I have had problems with the oil pan cracking, got that fixed. I check my oil every time I put gas in the car due to the fact that I knew the engine was using oil but it was nothing this severe. I would only have to add one or two quarts of oil every other week and I drive a lot for my job. I have never had any lights come on to warn me, there were no noises that was coming from the engine, I did not have any discolored smoke from the back of the car when starting it. There was never any leaks on the ground either. I had a Hyundai Dealership in Springfield, IL look at it and they said it just eats oil nothing more. I had my mechanic look at it and he stated that I needed to keep a very close eye on it, so that is what I did. However, no one told me that this was going to happen. Now I am stuck with car and payment that I can not drive. No recall but several/hundreds of complaints on same thing? And NO RECALL????

The engine in my 2017 Hyundai Santa Fe Sport, specifically the 2.4L Theta II engine, failed and is available for inspection upon request. This failure caused the vehicle to stall unexpectedly while driving, creating a serious safety hazard due to the sudden loss of power and control. The issue has been diagnosed by a Hyundai dealership, which confirmed the engine requires replacement due to internal failure. The manufacturer has denied warranty coverage, alleging maintenance neglect by the previous owner. Prior to the failure, the Check Engine light illuminated, the vehicle began making knocking noises, and it experienced a loss of power before stalling.

The crank shaft failed leading to total engine failure. It's currently sitting at my mechanic's shop until I can get this sorted out, it can be inspected upon request. My engine failed while driving 75 mph on an interstate and could have lead to serious injury/death of myself, my passengers, and other drivers around me. The problem has been confirmed by my mechanic, an independent service center. I had complained to my local dealership service department a year or so ago about the amount of oil my car was going through, and was simply told "that's just an issue with this make/model" so was essentially told to live with it. The vehicle has not been inspected by law enforcement or an insurance company. I had the oil changed on 11/30/23 to ensure it was full while travelling. The oil light never came on. The check engine light had come on about a year prior, was checked at my local dealership service center via computer scan, and was told they couldn't find an issue. When I had my vehicle taken over to the mechanic, his reaction was "Oh geez, not another one." Apparently he has had to replace several of these Theta II 2.4L MIP engines recently.
