2016 Hyundai Santa Fe: excessive oil consumption

Filed May 25, 2026 · Engine · NC

Purchased a used Santa Fe in January 2026 with 129k mile and at 131k my vehicle's CEL came on and did not function properly while operating. While driving the vehicle failed to accelerate above 25 mph when I pushed the gas. I pulled over to get out of the way of traffic and avoid any accidents. I shut the car off and sat for several minutes before restarting my vehicle. It successfully restarted and I drove home and parked it. I ran CEL diagnostic and received the code P0021. I had the vehicle towed to the local Hyundai dealer and they also pulled the same code and indicated I have an oil consumption issue explained as follows "Timing over advanced. Timing components driven by oil pressure. Inspected cylinders and borescope and found cylinder wall scoring and faulty piston rings. Radiator has crack causing coolant leak. Engine will have to be replaced to remedy oil consumption. Radiator will need to be replaced to remedy leak." resulting in over $12k of repair work. The vehicle's temperature gauge did not indicate any abnormalities nor did the oil light come on to indicate any oil consumption issues. The vehicle was driven from the dealer to my home within city limits/speed and has not replicated the acceleration issue but the CEL remains on as the repair is too costly and is more than what was paid for the vehicle.

Beginning about a month ago, I noticed a rattle upon the engine start up that lasted for a 1-2 seconds then stopped and everything sounded normal. I thought it could be b/c of the cold weather. I went in to get a routine oil change on 03/11/2026 and they said the oil looked fine, but it was about a quart low, indicating it was burning some oil somehere. They said to check in in a few months and they would top it up if needed. I asked them about the rattle and they thought is might be from a bad (timing chain tensioner) but said I should get it checked out. I called on Friday 03/13/26 to schedule an appt at my local Hyundai Dealership on 03/17 . The night before(03/16), I was driving my vehicle and suddenly on the road, I heard a loud noise in the engine, and the power shut off, the Engine and oil light came on and I just had enough time to pull off the busy state route. My car would not start or turn over. I had it towed to the dealership and they did determine that it was a "Rod Bearing Failure" that caused the engine to sieze. I provided them evidence of my oil changes which from 10k-93k miles on my car since I have owned it. I have had the oil changed 10 times. They are saying they only allow 8k between oil changes to honor the warranty and have initially denied my claim. The service associate at the dealership said my valvetrain was 'somewhat' dirty, but nothing to where it was the cause for this issue. And since it was the Rod bearing that failed, the exact part that was recalled, he was surprised they were not even offering any good-will offer, to split the cost of the engine replacement. I have reached out to Hyundai Consumer Affairs and am waiting to hear back to see if they will be fair and work with me on this to honor the warranty issue or at least share the cost burden for this "well-known" failure in their engine.

Car started to present problems at around 100k miles when it would start to hard shift any time it shifted in to 2nd gear. On several occasions it would fail to accelerate beyond 25 mph one of these instances happened while driving at speed on the interstate where pressing the gas pedal to the floor did not accelerate the car. Resently the engine would not turn over instead all of the display and indicator lights would flicker on and off rapidly. In all of these instances the car never through any codes with the exception of one time i May 2024 and were inconsistent enough that it was difficult to replicate issues when brought in for inspection. All of the above symptoms were alleviated by adding about a quart of oil every 1,000 miles or so. Again when asking about these issues the repair shops could never give a reason for why it was going through so much oil.

I purchased this vehicle less than a year ago from a dealership, used. I noticed the oil consumption after the first few months was unreasonably high. I have to keep a large jug of oil in my car and add the oil at least every two weeks or so depending on the miles I drive. I noticed other Hyundai owners complain of the same issue and some being resolved. However, my VIN is showing no open recalls at the moment.

Engine has serious recall that I was not made aware of during purchase. My car has been burning oil and the engine has been on. I've taken out to several local mechanics who said "these model Hyundai's burn oil once they are over 100,000 miles" and that I would just need more frequent oil changes. I was also told the engine light was either an old code being thrown, or the pump valve, but nothing to worry about because it really only effects gas milage. My engine went out and I had to get it towed to another mechanic, who upon seeing the car, knew it had an engine recall and could hear a distinctive knock in the engine due to a failing rod bearing. Upon Hyundai's request, we towed it to a dealership to have them inspect it. They agree it's the engine that's bad, but since a "knock sensor" was never installed by the previous owner, they say they are not liable to cover the repair, and that since the recall is "public knowledge", it was my responsibility to find out. If you go onto the website, and type in my VIN number, the information says "0 unrepaired recalls", therefore making it impossible for me to have known about the recall without Hyundai letting me know, which they didn't.

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 is consuming oil at an alarming rate. After 2000 miles, 3 quarts of oil was consumed

The vehicle will not accelerate over 30mph. I was entering the interstate on ramp and am not able to accelerate to the speed limit. The cars approaching had to slow down significantly to avoid a rear end collision. This happens every time whether I am at a stop light on a normal roadway or entering the interstate. There are never any warning lights or sensors indicating that there is a problem. I have completed all of the recalls and system updates required by the manufacturer. I have completed the oil consumption and engine cleaning multiple times and it has not helped the issue.

Seat belt on drivers side does not retract without assistance. I took it to Hyundai and they refused to fix it while the car was under warranty. The engine started burning excessive amounts of oil around 60K miles. We changed the spark plugs and found them to be covered in oil and corroded. We changed them again and they are worse. (Recommended every 100K miles.) The engine stalled once in traffic and continues to nearly stall when driven. The car has been burning in excess of 1 quart every 1000 miles since turning 75K miles. We were never notified of the engine failure issues with our SUV. At 96K mile it became so bad we took it in to Hyundai in Perrysburg OH Taylor Hyundai. We were informed about the engine issue and they began an oil consumption test. However the technicians when instructed to add 2 1/2 quarts of oil they added 5 ruining the testing. Then they claimed that the engine was only consuming 1/2 quart however we took a picture of the dip stick prior to brining it in and the oil was as always below the "L". We were then told we had to pay for an $800 engine flushing followed by 3 more consumption tests. Even if the tests show more than 1 quart of oil burning Hyundai may still refuse to replace the failing engine under warranty.

On July 26, 2021, I purchased a 2016 Hyundai Santa Fe SE. I purchased the vehicle with 90,168 miles on it, a current inspection, and a 3,000 bumper-to-bumper warranty. It has a 6 cylinder 3.3L engine. Since then, I’ve put 38,266 miles on it, and it’s ran without a problem. I’ve done all preventative maintenance, made my oil changes mostly around when needed in accordance with mechanics, and overall maintained the car as per recommended. On March 25, 2023, I was driving to work, and I felt a sudden loss of acceleration. I heard a knocking that I hadn’t heard before, yet no lights came on. No check engine light, no oil pressure light. My dashboard was not indicative of any problem. I ended up getting it towed to my personal mechanic, who was able to tell me that although the engine hasn’t seized up yet, it was surely not far from it. I was also informed that it was nearly empty. Now, I’ve had oil changes before and at no point has any mechanic, including those at my Hyundai dealership ever told me that I was short on oil. I had no puddles anywhere, at home or at work. I’ve had no smoke emissions from the vehicle to indicate that it was burning oil. To this day…I don’t know where 5 quarts of oil went out of my engine in two weeks. It is my belief that the only way this amount of oil could just vanish out of thin air is a glaring engine defect leading to near-catastrophic engine failure.
