The car has been consuming all the engine only after 700 miles. This has been a constant issue since December 2024 and the issue has been brought up with Hyundai dealership in Denville, NJ and Hyundai Corporate as well. Hyundai dealership in Denville, NJ performed 2 oil consumption tests, which the vehicle failed both test only after 700 miles as it consumed all the engine oil. They refused to do further investigation or recall the engine as it should be covered under Hyundai TXXI warranty given the Hyundai Engine II Class Action Settlement a few years ago. The vehicle has broken down on me on the highway a few times and has put my family at risk and danger due to the negligence of the Hyundai dealership in Denville, NJ and Hyundai Corporate refuel to resolve the issue. Now the car does not start at all some days thus it has impacted my work and my ability to provide for my family

The act is consuming all the engine oil only after 500-700 miles. It has been recored and tested at Town Hyudnia dealership in Danville, NJ after it failed 2 engine oil composition tests but the dealership did not replace the engine nor put in a. request to Corporate Hyundai to replace the engine as it should be covered by the 2.4L engine lawsuit a fe years ago.

The vehicle started to stall/drive in limp mode. I took it to the Hyundai dealership, and they quoted me $5000 for repairs. The repair recommendations were as followed: ensure connecting rod bearings are within spec, recommending performing timing job w/replacement of intake camshaft, e-cvvt motor/gear, e-cvvt cover, and other components necessary for repairs. This engine burns/consumes oil and the engine code that shows up in P00100. All of this after I paid it off. Not within warranty anymore either. $22,000 down the drain it seems... called hyundai customer service to see if there was anything that could be done but they said there is nothing they can do and I have to fix it even though it is a manufacturing issue.

Was going down the highway at 65 when my vehicle completely lost the accelerating component. Almost got rear ended so I pulled off. Then made it to work when it happened again. The engine light came on and gave 2 codes. Finally got it towed to the dealership where they have decided it’s either a new timing chain or new engine due to mechanical loss. They discovered there was no oil in the car and they have also found metal shavings in my oil. Now they are telling me I need a whole new engine. I only have 124000 miles on this car. The car was driving perfectly fine the day before and had just been to the dealer and looked over 1,500 miles before and I was told everything was perfect working condition. I am out $4000 on a car I bought a year and a half ago in October 2023.Was told my warranty only lasted a year.

My 2017 Hyundai Santa fe sport burns through 2qts of oil between oil changes (every 3000 miles). I check my oil once a week to make sure I have adequate oil to ensure my engine doesn't blow, Hyundai has open recalls on the 2017 models of my vehicle but my VIN number is not included...I have complained to Hyundai corporate and also the dealer and they state that I have to do an oil consumption test, at cost to me, to prove that their engine is defective...I first noticed this issue about 1 month after I purchased my vehicle, I was driving and my oil light flashed on for less than a second, I stopped at my sisters house and let my engine cool down and checked my oil and there was absolutely none... I refilled it and then began checking my oil weekly. I add at least 1/4-1/2 quart per week between oil changes. Every time I take my car in for an oil change they have to add an extra quart and make me aware that my vehicle is burning a significant amount of oil... This is my everyday car, I use it to get back and forth to work, I transport my children in this vehicle. There is a 953 Recall and also 218 but my VIN is not included.

In June 2024, my vehicle suddenly lost power while I was driving on the freeway, almost causing a serious accident. I managed to restart the car after being stuck on the shoulder of the freeway for several minutes. The same issue occurred the following day, prompting me to have the vehicle towed to the dealership. Hyundai Motor was contacted since the vehicle is still under warranty. The dealership informed me they would conduct an oil consumption test three times to diagnose the issue. However, they also stated that for the test to be successful, I needed to replace unrelated parts, including the brakes and transmission oil, among other items. Reluctantly, I agreed and spent $1,800 on these replacements. After completing the first oil consumption test, I returned for the second test. However, the dealership informed me that no further tests were necessary and returned the car to me without addressing the underlying issue. I emailed the case manager assigned by Hyundai to report this, but I never received a response. A few months later, the car failed to start. I contacted Hyundai again, and they dispatched a tow truck. The tow truck driver managed to start the car. A few days later, the issue recurred, and the roadside assistance tow driver suggested it might be the battery. Out of frustration, I paid $300 to replace the battery. Despite this, the car continued to make unusual noises at startup, a problem I had repeatedly mentioned to the dealership and in my communications with Hyundai. The situation reached a critical point today when my wife was driving the vehicle on the freeway with our five children inside. While traveling at 60 miles per hour, the car suddenly lost power again, putting their lives in danger. This is the third time this hazardous issue has occurred, and I fear for the safety of my family.

I have Hyudai Santafe 2017 Sport, bought it from dealership in 2020 with 46,000 Miles and in around past 4/5 years added 30,000 miles. Which is not much, in the past one year i have noticed that engine oil is burning faster than usual. On every oil change after driving between 1200 and 1500 miles the oil engine sign blinks and upon checking needed 2 Quarts of oil. I spoke the dealership and they are not very helpfull. Also they did the oil combustion test which i was charged. Later i was advised to do. ("Good morning, Just got off the phone with you sir warranty won't cover it due to the vehicle being out of manufacture warranty and mileage. My technician recommended starting with combustion chamber cleaning which would be around 1200 before taxes and shop supplies. Combustion chamber cleaning is the process of removing carbon buildup from the combustion chamber and intake valves of a fuel-injection engine. to see if that fixes the problem that you are having with the car burning oil. If that step doesn't work we we would submit a warranty pa again, to see if they would cover a new engine." Please advise what should be my next step, as per my mechanic the only solultion right now i have is keep adding oil carefully.

While driving on rural side road, two lanes, my check engine light (yellow, steady) came on. I pulled into a safe spot and did a quick survey, checked the owner manual, but could not identify any problem, and continued on my way. The check engine light was still on. About 15 minutes later the car would not accelerate past 25 mph (limp mode?). I was on a two-lane mountain road, speed limit 45 (but most cars were faster), visibility limited by terrain, trees, etc. Again, there was little traffic around me and I found a safe place to pull over. in neutral the engine revved normally. I turned the ignition off, checked oil level, (normal), turned the engine back on and started driving to find a safe place to pull over and summon help, but the car drove normally. I drove directly to my repair shop and had the codes pulled, (0436, 0021) which indicate a problem with timing. When a qualified tech examined it he recommended taking to the dealer. Unwilling to drive in traffic, I had it towed to the dealership. Their inspection revealed damage to CVVT components and the timing chain, and recommend an (expensive) engine rebuild.
