Oil consumption issue. At anytime the engine could fail and shut off making for unsafe driving and causing an accident. In progress, have done one consumption problem test and about to do a second. Oil light went on after an oil change and had that inspected at local garage. After that oil change within a week or so took back to garage and oil was down again after 735 miles and took it to the Hyundai dealer in Meriden CT after waiting 3 weeks for an appointment. They won't commit to saying it is a problem until they do more costly tests but it is evident it is the same problem my daughter had with jeep until they finally did a recall. Problem began in Feb but I went away and continued with issue when I got back at beginning of May. Have seen the same complaints on the internet and lawsuits etc.

Have 80,000 miles on vehicle, driving down highway, and total engine failure occurred. Luckily there was a highway shoulder I was able to roll onto for safety. No oil light had come on, but mechanic said there was an internal oil leak, and that I had no oil, and engine was blown. There are many known engine failures due to excessive oil consumption in the 2018 Hyundai Santa Fe Sport models. They need to offer a recall on this model and replace the engines of thismodel.

engine failure misfire, oil consumption

- Fort Myers, FL, USA

Excessive oil consumption has occurred for the past couple of years. At 80,000 the crankshaft seized and died at an intersection and the dealer said that I need a new engine.

- North Canton, OH, USA

For the last year or so, we have had a major issue with oil consumption, there are no oil spots on our driveway yet the oil just disappears and we are constantly having to add more. I have spoken with Hollar Hyundai about the issue and they acknowledged there is a problem and that the SUV now has a lifetime warranty for the engine. We have all records of oil changes and my wife is very religious about getting it done as scheduled. We asked about what we are to do and all they said was drive the vehicle until the engine siezes up and then Hyundai will replace the engine. I asked about doing the test on the engine nd they will not do a test on the engine for us. We are at our whits end with this engine using so much oil and we need to have soeone from Hyundai Motor America contact us and help us resolve this issue. My wife loves our SUV and it is the first one she has ever paid cash for due to inheriting some money and now she is faced with the possibility of having to trade it in on another vehicle and thus coming out of pocket or even aking car payments again. PLEASE HELP US WITH THIS KNOWN ISSUE!!!!!

While driving my 2018 Hyundai Santa Fe Sport in freeway traffic, I felt the vehicle begin to heavily vibrate and the engine was jerking severely. The speed began to slowly descend. I was unable to control this. I was in a one-lane overpass, with no safe place, room, or lane to pull over. I felt hopeless and fearful for my life. I was literally drifting, praying the vehicle would be able to handle the descent upward. As the speed declined, the vibrations became more pronounced. No dash lights were illuminated. Other drivers behind me were approaching rapidly at the speed limit and slamming on their brakes and hazard lights in an attempt to notify drivers further back. I managed to maneuver over to approximately 24 inches of a faux shoulder on the right of [XXX]. Cars hurled past mine within inches of my vehicle. I knew I needed to get out of the car and crawled over to the passenger side. Again, I was trapped. Several HPD units were dispatched to literally shut down the freeway to enable a tow truck driver to safely hook up my SUV. I had it towed to my mechanic and he did a diagnostic indicating a compression issue. He ordered new spark plus and 4 new coils. Upon further investigation he discovered that Cylinder 4 was not holding compression and he informed me that the engine had failed. I then had it towed to the local Hyundai dealer. At check in, I was informed that there would be a $700 diagnostic/tear apart fee to discover what repairs were needed. I informed them exactly what was needed and I expected a new engine. The Hyundai mechanic dismantled the engine and took pictures, ran a few tests. He submitted the results to Hyundai for approval. The engineer at Hyundai denied a new engine claiming "the head coil is not part of the recall". I was told for $2500, Hyundai would "refab" my damaged head to control the leaks. If that repair didn't address the issue, I was sure to get a new engine. A financial and physical risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

I just got Hyundai SUV last December and already cause problem with engine and abs, after I found out that it is recalled a while ago. First ABS, I was going to fix that but all attention to me is engine light then found out it is High pressure fuel pump then burning oil that I smelled something isn't right. I feel it's not safe to drive and I spoke to mechanic, He told me take it back to dealership that they gave me a lemon Hyundai.. I talked to the dealership mechanic shop and never tell me anything how much for high pressure fuel pump? SO I already saw my SUV problem and I decided to check website for Hyundai recalled, that what I had right now.. It's only 6 years old and only 90,000 mileages on that SUV. That smell is very odd and it will cause engine fire..

Hydndai will not fix my engine until it catches on fire and or seize- There was a lawsuit and as per the settlement - the warranty is extended for the engine but the claim form and service agent said in order for the engine to be approved for replacement I would have to wait for it to seize or catch on fire. As a mother who drives with her children I find this unsafe for them or to others as this can cause an accident and or it can be fatal. They still have these recalled vehicles in there lots and our scamming people!!

- I experienced an engine failure while driving. - I was in traffic the auto lost power and I had to immediately pull over. The immediate loss of power caused traffic to break. Fortunately, there was no incident but it could've been dangerous in a more congested area. - I had the vehicle towed to a dealership. - The dealership has looked at it. They submitted a report to the manufacturer over a month ago. - I saw the engine light flash and heard clattering coming from the engine compartment.

Oil pan has a crack. On 03/15/2024 while receiving maintenance on car service personnel notified me that I had a crack in my oil pan and that it would have to be replaced. I have seen no signs of a leak in my driveway. Said they will replace for $395. Seems to be a common problem with Hyundai cars. Looks like a problem with the manufacturing of the oil pan.

During a dealer-suggested "oil consumption test" and driving down the interstate with cruise control on, SUV suddenly started experiencing reduced power and emitting a burning smell with no apparent warning lamps or messages. Exited the highway immediately and came to a stop on the side of the road and engine quit before even being able to put it in Park. Engine is 2.4L in-line GDI Theta II. Hoping to tow it to the dealer by week's end to have them pay for a replacement engine and get reimbursement.

While driving in the Highway, my car lost engine power and lead to my car run no more than 40 miles per hour, after this I took my car to the garage and the said it was the knock sensor that course this issue. After being in the garage, my car knock sensor was replace for a new one to make sure this was giving good reads and while driving in a two way street it happen again and I believe this could be very dangerous if it happen while passing another car on in a crossway. Yes. Yes. As soon it happen the check engine light started blinking. It happens 3 times end of Nov 2023, early December and late December 2023.

Engine died on highway. Noc sensor code indicates is a known problem for this engine. 2.4 liter Hyundai sante fe sport. Before engine died was burning much oil even after oil changes and borught in for recalls to dealer 2 mo before. Excessive burning of ooil wa a know issue at that time July 2023. Now Hyundai dealer saying the issue is a customer issue due to carbon build up on a valve. High burnin rate of oil is responsible for the carbon build up on the valve causing the engine to fail. Not a cusotmer problem but a engine design issue.

- Westerly, RI, USA

The check engine light came on. The vehicle attempts to stall when changing gears after a stop or deceleration and the engine shutters at speeds 65mph or greater. I am afraid the vehicle will stall if a fast acceleration is required such as moving onto a highway. A diagnostic was performed to confirm the engine is causing the "Check Engine Light or Service Engine Soon Light."

- Norman, OK, USA

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.

- Elizabeth, CO, USA

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.
