2018 Hyundai Santa Fe Sport owner complaints

The vehicle developed loud engine knocking and abnormal noise consistent with known Hyundai engine defects. The vehicle is unsafe to operate and has been retained at an authorized Hyundai dealership since October 25, 2025. Hyundai vehicles with similar engine failures have been documented to catch fire, including while parked. Despite the known defect pattern, the manufacturer is refusing warranty coverage, alleging lack of complete oil change records, without providing proof that maintenance caused the failure. This represents a serious safety risk to occupants and the public. My family includes a child with a motor disability, which significantly increases the danger in the event of fire or engine failure.

This is a certified preowned vehicle. I am the second owner. I do my own maintenance. Currently this engine/vehicle has 64553 miles, I noticed it starting to use oil around the high 40k mile mark. There are no oil leaks. I have to add oil multiple times between oil changes and I just read that some of these can lock up and completely stop. I suspect this would be caused by people not checking their oil regularly however I am concerned that is the oil consumption is bad enough that this can happen at any time while driving so I wanted to add my complaint to any other existing complaints.

2018 Hyundai Santefe 2.4L engine burned oil at a high rate and due to this caused 4k oil changes obsolete. The car need an oil change every 2k miles and still would have high build up. Hyundai claimed engine failure was due to gaps in the oil changes them being done around 4.5k miles in the start. Many people have had engine failures with these car and they are still selling them with the defective engine to this date and not warning the buyers about the problems with these cars and are forcing the second hand buyers to pay $6-12k outta pocket to repair these cars after a year of owning them. I think Hyundai should be held accountable for these actions after they know these engines are defective and they still have them on their car lots for someone to stroll in and buy a $17k car with pre

Driving on highway, when accelerator failed to maintain, the car started to jerk. After blocking traffic behind me, I was able to pull car over on the side of the busy highway, with smoke coming from hood. This was well after dark, and it was towed to a local and dependable mechanic. He had told me the engine was cracked. I am in the process of finding out if I am eligible for the extended warranty, for I meet all requirements

I was on the highway and pressed the gas and the car started shaking. Wouldn’t go up in speed so I pulled off the highway and parked it. Checked the oil and it was almost empty even though I had an oil change about a month ago. Service center says it need a whole new engine at 108k miles. How is this possible? They say there were pieces of the valve in the fourth cylinder which also had lots of oil in it. I bought this car used and am only the second owner. Surely there is something Hyundai can do if they know about this issue.

HIGH OIL CONSUMPTION: To the documented tune of 40 quarts consumed April17 - December 15, 2023, encompassing 24,116 driven miles. Hyundai America and this dealer knows all about this issue and is stalling on the remedy because it requires total engine replacement. Presently I am experiencing a P1326 engine knock sensor fault and I'm told by my mechanic a prospective catalytic converter failure due to high oil consumption. Experiencing loss of power and NO acceleration merging onto highway.

The component that is malfunctioning is my engine. I took it into the dealership and they said I had cylinder scoring on my engine from excessive oil consumption. My safety was put as risk as my car threw itself into limp mode in the middle of the high way while going over 70 mph. I had to immediately pull over on the side of the highway and somehow get it back home while not being able to accelerate fully. My car is not drivable in this mode as it is unsafe. This issue has been confirmed by a dear shop although they refuse to replace the engine unless I pay for it out of pocket which is not possible. The vehicle component was inspected at the dealership. There was no prior warning to the engine issues. If there had been oil consumption issues before I had just recently bought the veh

The contact owns a 2018 Hyundai Santa FE. The contact stated that while driving at 30 MPH, the was a burning oil smell permeating the interior of the vehicle. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the piston rings in cylinders one and three. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V301000 (Engine), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 7,000.

My 2018 Hyundai Santa Fe has a blown engine and will cost over $9000 to replace. Unfortunately my car is out of warranty at 120,000 miles. It has become known to me that this particular car, and thousands of others, has known problems with the engines. So much so, that a software update for a sensor was available in 2017, oil consumption issues and civil law suits have been highly publicized. I was never notified of the software update, which would have extended my warranty to 10 years and 120,000 miles. I was diligent in oil change and maintenence on my car yet of no fault of my own the engine needs replaced. I believe Hyundai has been aware of these defects and did nothing to rectify the company-wide problem, just hoping many cars would fall out of warranty first. I have been told that

The engine is sucking oil faster than it normally would and could put me at danger. If it sucks up too much oil too soon I could lose control of my car in the winter and be the cause of an accident.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while driving approximately 60 MPH, the vehicle made a loud banging sound coming from the engine compartment. The instrument panel illuminated with several unknown warning lights. The vehicle then lost motive power. The contact was able to coast to the side of the road. The vehicle was towed to the dealer who diagnosed that the engine failed due to a connecting rod going through the engine. The vehicle had not been repaired. The manufacturer was made aware of the failure and the contact was informed that the repair would not be covered under warranty or recall. The approximate failure mileage was 97,000.

My vehicle hesitates randomly upon acceleration after having stopped.....going from first gear to third....it feels like it is about to stall, so I let up on the gas pedal and then immediately press it again to accelorate.....as I then accelerate, the vehicle lurches forward abruptly, jerking everyone inside the vehicle....in reading about this problem, it seems to have occured in your 2017 santa fe sport suvs.....

I got into my vehicle and when I closed my door, my rear window exploded. There was no one around the vehicle. There were no other vehicles broken into, it literally exploded on its own.

There appears to be a problem with the intake manifold. Car is throwing a code of P200A. The baffles get stuck causing the car to lose power, usually 3 times in a row. I nearly got rear ended twice because of this and it threw my husband an myself toward the window.

I have been experiencing issues with oil consumption, having to get oil changes every 2 months and sometimes monthly with no reported leaks from 2 different mechanics. I have been very high maintenance over my oil. While I was driving on the highway, my vehicle began to shake and a knocking sound was heard. I felt the vehicle begin to jerk but no warning lights were on. I was no longer able to drive and had to pull over and wait for a tow to my mechanic's garage. The mechanic let me know there was an issue with the engine, specifically the 3rd cylinder and the piston. It does not put out as much pressure as it is supposed to. I brought the vehicle to the dealership after and they confirmed this was an issue and quoted me $8700 in repairs. There were no warning lights and no engine lights

On January 30th 2023 we made an appointment to take our 2018 Hyundai Santa Fe Sport to our local dealership in Newmarket Ontario Canada due to a clunking in the front end of the vehicle. On inspection our 2018 Santa Fe Sport was identified as having a BROKEN COIL SPRING on the driver side. Along with this inspection it was also noted the passenger strut/shock had been leaking and was out of fluid. The Newmarket Hyundai Dealership considered this to be an emergency repair. This was determined because the coil and or both coils could totally break and puncture the front tires. This information I obtained from the Hyundai recall 167!!! Although according to the recall seemed to be only in America we truly believe our 2018 Santa Fe Sport in Canada falls into the same category of the Hyundai re

Driver seat belt will not latch properly. I have not spilled anything into it an have checked it for debris. If you jiggle and push slightly on the unlatch button while trying to insert the buckle it will sometimes latch

Purchased vehicle in june 2018 and noticed a problem with headlights, shadow on roadway when driving. I noticed in housing that there were finger prints on lenses and took vehicle back to dealer for remedy...they replaced headlight on driver's side. Did not think anything else about it until I drove the vehicle during darkness. Shadows were observed on side of road that could and did hide bikers/walkers on the side of the roadway. Upon closer inspection of the lights while parked, I noticed that these shadows were also observed on the passenger side. Passengers in vehicle also noticed headlight problems on both sides of vehicle. I contacted dealer about this problem and was told that this was made that way during manufacturing. As time passed, anytime that I took vehicle out during n
