2018 Hyundai Tucson

The oil sensor doesn't illuminate the light on the dash when the oil level becomes low. The only warning is when it becomes really low and then the check engine light will appear. It's a safety concern due to the engine possible failure and or damage may occur at that point if continuing driving happens. This causing the engine to stall and loss of control of the vehicle. Which could lead to a vehicle crash resulting in injury or death to the occupants and or others nearby.

1.The engine is consuming oil excessively. 2 and 3. I was informed during a service visit that this is a common problem. I asked how to get it fixed and was advised to lock the engine up. I informed the service advisor that I would not lock the engine up and told him I have a [XXX] son. I told him I'm trying to do everything I can to prevent that very scenario. 4. Yes, I will provide records. Additionally, a class action lawsuit was filed in California under their Lemon Law. Do a quick google search. Everyone I have spoken to at the dealership has confirmed they are all well aware, however they can only do what corporate allows under the Warranty. I am the first and only owner supposedly covered until 100k miles. This problem began at 79k. I'm at 86k and still struggling to get anything moved forward. 5. Unknown 6. My oil light flickered briefly but never stayed on. I immediately checked to discover not a drop on the dipstick. I will provide photo. My oil has been below the low mark several times since this photo and has never come back on. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1.What component or system failed or malfunctioned, and is it available for inspection upon request? Engine is failing/malfunctioning. Yes it is available upon request 2. How was your safety or the safety of others put at risk? No oil can cause an engine to overheat and/or catch fire. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by Hyundai of Medford. Oil consumption test was completed. Preauth was submitted for a new engine and was denied. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, inspected by manufacturer (Hyundai of Medford). No leaks or other issues that could cause this were found. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, no warning lamps or messages were shown or sent. Even when low on oil. Consuming oil extremely quickly. Oil change was completed and I was only able to drive 700 miles before I was low on oil. I have history of oil changes and top offs every 1000 miles for about a year. It has only gotten progressively worse. Hyundai of Medford Confirmed the issue and confirmed there were no oil leaks or other issues that could cause this. They recommended I request a new engine for Hyundai. I submitted the Pre-Authorization and it was denied. After more research I have found that thousands of people have had the same exact issue with the same year, make and model of my care. There is even an entire Facebook group dedicated to this issue. The manufacture needs to be held accountable for these faulty engines. Thousands of cars should not need a new engine before they reach 100k miles. I am writing hoping to shine some light on this issue that is effecting thousands of Hyundai owners.

In late September of ‘24 my husband was driving our oldest to school when my 2018 Hyundai tuscon seized mid drive with our son in the back seat with no oil or engine light warning. Husband inspected the oil and I was still full. A Hyundai dealer towed at their expense in October, diagnosed an engine failure. Denied me service since my extended warranty expired and I didn’t have the KSDS update. I wish they would as I still owe on the vehicle and I’m out of work. Making this complaint is to only spread awareness that 2017 Tucson with the 2.0 L engine had an engine failure connecting to rod bearings. My 2018 has the same engine type and failure as the 2017. Hyundai Corp fails to recognize the problem. My 2018 didn’t fail due to lack of oil changes as I can I prove that. My 2018 failed on Hyundai’s fault. Now my car sits at the dealership in Anchorage, Alaska and I still owe 9k and I live in Fairbanks, Alaska. 360 miles away from me.

Engine had oil consumption problem. We bought it as second owners around 89k miles. Now at 98k miles and engine has blown. It’s not going to be fixed without a replacement. We are getting the run around by Hyundai in ballwin asking us to pay 500 upfront and all kinds of pushback. We have to tow and they will look at it even though it is still under 100kmile powertrain warranty. We got 3 months use out of a vehicle we just paid 15k for. Total loss

I own a Hyundai Tucson 2018 model and recently it started making the noise. i got it check with the private auto shop and they said it the engine issue so i took it to dealership as it was under the 100,000 power train warranty. The dealership ask me about the invoice of regular oil change invoice which i provided to them but they simply denied it. the dealership is located on route 1 south Brunswick new jersey.
