High oil consumption leading to costly repairs outside of warranty.

NHTSA ODI 11697382

Vehicle is burning an extreme amount of oil between regular oil changes. We are having no help from our local dealership in Tuscaloosa, AL where we purchased the car to resolve this issue without first spending a lot of money to diagnose an issue we certainly already have. Long before it was due for routine oil change, we checked it and it was COMPLETELY EMPTY of oil. NOTHING IN IT. We have to put oil in it three times before its next routine service. We have always had the vehicle serviced, on schedule, by our local Hyundai dealership and are the only owners of the car.

The contact owns a 2020 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the low oil warning light briefly illuminated. Upon inspecting the vehicle, the contact noticed that the engine oil level was low. The vehicle was taken to the dealer, where the contact was informed that the engine was not consuming oil and that an oil change was needed. The dealer advised the contact to return after 1,000 miles to inspect the oil level. The vehicle was taken back to the dealer; however, it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 72,000.

Engine oil excessive consumption/burning oil

NHTSA ODI 11693922

In between my last 3 oil changes I have “lost” all of my oil in my car. Checked my oil randomly and there was NO OIL at all on the stick. After this last change I have checked it every week. I did not check for 2 weeks less than 1,000miles and it was below the low on the mark. Obviously running out of oil while driving is not safe and can cause the engine to blow. This can cause a crash or fire. There have been numerous issues with this and the cars need recalled. This is ridiculous.

the car started using a little oil around 80,000 mile, and its just gotten worst , to the point that's it using 1 quart per 150 miles the car runs ok but its ridiculous the amount it is using. and from what I've found researching there is a lot of complaints

Car broke down first time about 2.5 months ago. It was towed to Fred Beans Hyundai of Doylestown PA and they did oil testing on it and I was told that the car was burning oil too fast. They told me under warranty they needed to do a carbon combustion cleaning. So that was down, and less than 24 hours of having the car back, the check engine light came back on, the car wouldn’t drive above 50 miles per hour, and was jumping forward (the same thing that happened the first time) I had the car towed back to the dealership and they told me there was still leftover carbon and it needed to cleaned out again. The car was fine for about 2 months, however just today it broke down again. Same problem, check engine light came on and started flashing, the car will not go above 50 MPH and it jumps forward. I have now been given back a car that is unsafe to drive and put my family and 2 times. Clearly the dealership is not fixing the actual problem at hand and continues to put my family and i’s safety at risk. Each time the car has broken down I have been on the pa turnpike and been put in an extremely dangerous situation.

Engine is consuming 3+ quarts per 1000 miles. There is no low oil warning light or notification, just a low oil pressure light which could be caused by many things that would not cause a vehicle fire like low oil would. Hyundai was contacted and we were told that all we need to do was get our oil changed with them, come back in 1000 miles to check the level, if it was consuming greater than 1 quart per thousand miles we would be scheduled for a combustion chamber cleaning (service tech said this would do nothing to solve the issue), drive 1000 more miles and check level again, and if it was greater than 1 quart per thousand we would be scheduled for a new engine. They were informed that we were the second owner and we were told that shouldn’t be an issue. After completing the oil change and going in after 1000 miles we were told that the engine consumed approximately 3 quarts of oil. That information was apparently submitted to Hyundai and they said we were not approved for the combustion cleaning because we were the second owner. The safety of the vehicle was not taken into account at all and Hyundai did not show any concern of vechile fires even though low oil is a contributing factor to many scenarios that can cause injury or death.

This call actively has a recall on engine rods any Hyundai and some Kia models ranging from 2011 all the way until 2022. They are known for having a faulty motor with active oil consumption and are currently facing several lawsuits and my car is one of these cars facing this issue however, the manufacturer doesn’t want to Fully create a recall on the motor claims that are causing this rapid oil consumption issue I would like this to be investigated as well as it be investigative why you don’t already have their current active recall listed on your website . but if your website was correct and listed the engine, Roddery call, and if my engine rod were to blow, then they would actually address this issue however, some people are getting this issue addressed under their manufacturer warranty however it is becoming extremely difficult because they want us to pay out-of-pocket for a pointless test as newer vehicles should not be burning oil with no active problems. Clearly, the states there is a problem which there is as of all the active lawsuits.

The oil pump failed, causing the car to die while on the interstate. There was no prior signs nor warnings to this issue, and it caused the engine to lock up, meaning that the engine now needs to be replaced. This is not unheard of with Hyundai’s.

2020 Hyundai Tuscon engine continually consumes an excess amount of oil on a weekly basis causing cylinder knocks. This vehicle has been routinely maintainanced and continues to experience this issue which is an issue known by the manufacturer and has yet to be addressed seriously by the manufacturer. The vehicle is just out of warranty; however, the issue stems from known engine faults that are the responsibility of the manufacturer.

The check engine light became flashing and the vehicle went into limp mode while occupied by two adults and one minor child as they were merging to access the freeway

I went to Thompson Automotive to finance a vehicle and within a month and half my engine blew. There were no engine lights, no lost of oil, no warning, no signs of any error, before this series of malfunctions took affect. I was on my way to the dealership and my car being slowing down to a complete stop as I was getting off the highway ramp. I was traveling at the speed of 25mph, when the car started to make loud noises that I never heard before that day, and completely shut down in front of a huge tractor trailer in traffic. The dealership has had my car since 6/7/24. Now the car has about 85,000 miles on it. I have to pay another $3,000 for my portion to get a new engine. Which is outrageous considering I just agreed to pay $19,990. I am highly disappointed that I lost my job and everything behind this horrific situation that actually feels like a set from the beginning. Now that I’m reading all the comments and unfortunate but very similar situation everyone is suffering from with the particular car. I can’t fathom why it’s still on the market to be purchase for consumers with these major and potentially deadly problems.
