While driving uphill at 40 mph the car would not accelerate and the mph began slipping down to 30. There were no warning lights during or before this and no other changes while driving. A clicking/rattling noise became louder as I drove on. I made it up the hill and to the next stop light. When trying to accelerate, the vehicle would not go past 20mph and the clicking/rattling noise was very loud. I drove approximately 2 miles to get home. The next day at the dealership they stated I needed a new engine and there was no oil in the engine. I am up to date on my oil changes and never once was notified my engine had a problem during any of the inspections. We had to replace the the transmission around 90,000 miles. The car currently has approximately 113,000 miles.

2017 Hyundai Santa Fe Sport 2.4L automatic, took the car in for recall service. The following recall services were completed: (23-01-014H-5), (23-01-004H), (20-01-006H), (#17-01-050), (17-01-002). Service completed on 07/25/23, car was in perfect working order prior to recall service. Picked car up from dealer on the afternoon of 07/25/23, drove about 5 miles home. Next day (07/26/23), drove car about 20 miles and engine light came on. Took back to dealership 07/26/23 at about 3pm, stated nothing they did would cause engine light to come on and wanted me to leave with vehicle without checking it. Said 8/1/23 would be the earliest the could look at it to even check the code. Refused to leave with car in that state so they did check the code and stated it was a catalytic converter code and that mine might be going out. Stated that nothing was wrong with my car prior to recall services. Then they asked if my engine light was on before I brought it in for the recall service, I stated no. Then they said it could be the engine software update reading something wrong and cleared code. Told me to drive vehicle and if it came on again to bring it back. Drove car home again which is about a 5 mile distance. Did not drive car next day (07/27/23. Drove car on 07/28/23 for about 20 minutes and the engine light came back on. Called the dealership and they stated they would call me back but never did. Called the national Hyundai customer service number and explained the situation. Gave me a claim number and stated a case manager would contact me in 3-5 days. Called the dealership again on 07/31/23, and left another message with the service person but they did not return my call again. Called on 8/1/23 and asked for the service manager who stated earliest they can look at my car again is 8/7/23. Have not been contacted by a case manager yet as of 8/1/23. Hyundai forams online clearly state other owners having same issue as mine after having the Hyundai software updates completed.

This is an OIL CONSUMPTION & ENGINE FAILRE Car was being serviced by Hyundai for oil consumption test, and failed, 1 quart of oil consumed every 400 miles. On 7/23/23, engine failed on PA turnpike while travelling 70 MPH, and almost caused an accident. At 65k miles Hyundai agreed to to conduct oil consumption test, and submit for engine replacement, First part of oil consumption test failed, and car was set for engine under Hyundai warranty, but 2 days prior to cleaning engin failed. Engine has had high pressure fuel pump replaced, and I reported gas smell from oil Catalytic convertor was replaced @ 55k miles, as oil consumed burned out convertor. Now that the engine valves are burned, Hyundai is not honoring the good faith engine replacement.

The engine was making a knocking sound and the check engine light came on. I did not have the time to get it to a mechanic (approx 2 days of driving with knocking) before the knocking stopped and the engine stopped. The car stalled out in the middle of the street and I was able to coast to a complete stop on the side of the road and push it to safely back home.

- Las Vegas, NV, USA

Catastrophic engine failure at 86,200 miles. Engine making chugging and ticking sound and metal flakes in oil. Normal oils changes at Hyundai dealers every 5-6k miles (or 6 months). Hyundai wouldn-??t cover because 2nd owner (should have covered up 100k power train.

Engine failure - Engine had failure while highway driving (approx 60mph). Complete loss of power in roadway. Mechanic diagnosis indicated piston rod had disconnected and caused hole in engine block.

- Decatur, GA, USA

A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the -??check engine-?? light in the instrument cluster. Illumination of the -??engine oil pressure-?? warning lamp. My car will drive up to maybe 37mph and then the engine will seize up and go into safety mode and it becomes inoperable. THIS is a death trap if we suddenly stall out on the highway or at a higher rate of speed!!!! The dealership is basically saying oh well, it is out of warranty. I just bought this car from Banister Nissan on 6/5/2023. Less than 60 days ago.

While driving on freeway there was a clicking sound coming from the engine area but no other strange sounds or sensations, no warning lights or changes in the dash gauges. Finished 30 mile trip back home. Next morning when starting the car the same noise was happening so we checked oil. Oil reservoir was empty so added 4 quarts and let it sit for awhile then idle before leaving. The clicking noise seemed be random, sometimes louder and faster and sometimes not clicking at all. Approximately 15-20 miles down the freeway (about 60 mph) the RPMs spiked so I moved to slow lane and braked. At this time a large commotion from the engine that shook the car with large amount of smoke coming from behind the car and an oil trail. Car was towed to mechanic where engine failure/hole in engine was diagnosed. Waiting for appointment now at dealership. Fortunately never lost control of the vehicle.

At 80,000 miles, transmission went out. Then, 91,000 miles the motor locked up. Hyundai refuses to repair

At ~126k miles, my 3.3L Santa Fe started knocking and then stopped running. There were no warning lights whatsoever. Regular service records are available to show oil changes/maintenance and all repairs done at the dealership. Mechanic says the engine is toast. Hyundai dealership told me no need to even bring it in bc it will not be covered.

The engine failed in our 2017 Hyundai Santa Fe earlier this year (March). They replaced our engine after finding out it was part of the rod bearing engine failure recall. The check engine light came back on as soon as we got it back (April) and the car has not worked properly since. Shaking badly, it also died after I started it. After them telling us for two months, they were too busy for us to bring it back to them. We finally brought it back this week and dropped it off for them to fix anyway (July). The Hyundai repair people told us the problem is not covered under the warranty (vcm motor on the side of the intake) and not related to the engine recall even though the problem happened immediately after they rebuilt the engine and now we must pay $1000 out of pocket.

Engine started knocking pretty bad during a trip. Just over 80,000 miles not covering due to 2nd owner.

As I was driving my vehicle the car started to shake. I was able to make it to a gas station and then had difficulty getting the car to turn over. After several attempts the car turned over but the check engine light was flashing and the car had fumes coming out the back. I towed the car to the dealership I bought it at they determined that the fuel injectors failed and caused the engine to be flooded with gas requiring an entirely new engine to be put in the car.

Since early 2022 I have been having oil consumption tests done on my vehicle, after having an oil change and 2 months later, during my inspection, being told my oil is completely dry (no warning lights came on at all). There was an oil combustion done, which the dealer had to keep my car and put me into a rental (after me pressing the issue of a rental or loaner). I am now on my 2nd round of oil consumption test. I had an oil change done the last week of May, took it back 932 miles later because my oil light quickly came on then went off, when turning corners and coming to a stop on level ground (the light did not stay on) and it burned 3.5 quarts in 932 miles. It has gone from burning 2.5 quarts in 1,000 miles on the very first oil consumption test in 2022, to now burning 3.5 quarts in less than 1,000 miles. Last summer there was oil on my spark plugs from the oil consumption, but I had to pay out of pocket to have them replaced. This last time I went in June, the dealer stated they will contact Hyundai about replacing the engine. It has been 2 weeks and I've heard nothing yet. This is a huge safety & fire concern that I feel Hyundai is taking way to lightly! It is a huge inconvenience as well to take off work, leave work early, go into work late, pay for rides to/from the dealer, put oil in my car, etc. I asked about a loaner for times they wanted to keep my vehicle, and they responded that they do not have any available. Rentals should be covered 100% if they do not have a loaner to give us. When I was put in a rental, I had to pay the deposit because that is not covered by Hyundai. Reading about all these issues, I am not sure why Hyundai has not put out a recall on this issue, instead they continue to put us and our families at a big time risk!!!

While driving my 2017 Santa Fe, a ding from the instrument cluster preceded the vehicle stalling during a turn in a busy intersection. The vehicle would not respond to attempts to restart. I had the vehicle towed to the local Hyundai dealership for inspection. I authorized a teardown of the engine. They reported their findings to Hyundai Motors America (HMA) for authorization under an extended warranty. That request was denied. I have read the case, Davy Cho v. Hyundai Motor Company, Ltd., 8:22-cv-00448, (C.D. Cal.). My vehicle is in the correct year range and engine class represented in the suit. This vehicle is also under NHTSA investigation (DB22-003) for a separate defect that can cause the vehicle to stall without prior notice. The Hyundai dealership has now quoted $19,900 to repair. This is a gently driven and well maintained vehicle. I have reached out several times to HMA who states, the vehicle is beyond the original manufacturer's warrantee. I have tried several times to have the case reviewed. I'm told these decisions are final. HMA Case # 21352488 I was lucky to have had the traffic lights and traffic in a condition that I could drift through my turn, apply hazard lights and get assistance from the Police Dept. who closed the road allowing me to coast the vehicle backwards off the interstate bridge to place me and my vehicle in a safer place to manage. In different circumstances, this could have been catastrophic.

Hyundai corporate's engines on some vehicles has oil dissipating out of thin air. 2 to 3 quarts of oil can vanish between regular interval oil changes. Hyundai is lying saying that this is "normal." It is not. The other issue is the oil indicator light may just pop on and off but it does not stay on when the vehicle has several quarts of oil that dissipated not warning the driver they have a serious problem. This leads to a safety concern because the vehicle could just stop working because the driver has no idea the oil is low. I urge the NHTSA to take action on this since so many vehicles with Hyundai are affected. Thank you.

Hello. I don't know if this is even something you look into, but I wanted to see. Yesterday when I came home from work my oil light came on and all of my oil suddenly dumped in the driveway. I am thankful I was at home because this could have been a nightmare somewhere else. I had my car towed and was advised that the rear main seal needs replaced as well as the oil pan gasket. I don't know if this is a safety issue, but if my engine would have seized on the highway that could have been a nightmare. Oil maintenance has been at regular intervals. There was no warning until my light came on in the driveway and then the immediate dump of oil. I'm happy to answer any other questions. Thank you. Brooke

Was driving my 2017 Santa Fe Ultimate 3.3L v6 at a low speed on residential streets. With only 110,000 miles without warning or indicators the engine failed. Regular schedule oil changes were preformed. Hyundai wouldn't offer any goodwill financial help with a engine replacement, stuck with a car loan and work working vehicle.

Check engine light came on, made an appointment to bring to the mechanic. 1 mile into the trip, engine lost power. We had to tow to the mechanic. Synopsis: hole in block caused by catastrophic engine failure at 120,000 miles. When check engine light occurred, oil was at correct level; and vehicle has always been maintained properly.
