The check engine light came on in my 2016 Tucson, which only had 77K in mileage. I had it towed to a Hyundai dealership in Richmond, VA. They reported that there was a rod beading issue which would require a total engine rebuild for $15k. I have since learned that there was a class action lawsuit against Hyundai. This recall included the Theta II engine, not the engine in my 2016 Tucson, which is a 1.6 Turbo. The defective part in the Theta II engine is the same defective part in the 1.6 Turbo. When the engine malfunctions, it can cause the engine to go into limp mode which prevents acceleration, it can cause the motor to seize up, or it can cause engine fire. When I contact Hyundai customer service and explained my concern with the engine not being covered in the lawsuit, they admitted that it probably should have been. While the dealership is blaming the issue on a missed oil change, it is a known fact that this is an ongoing issue with the engine. I have documentation attached from my local mechanic sharing the notification Hyundai Technical Service Bulletin. I have since done a lot of reading about the issue with this motor and I have joined several social media groups whose members have all had issue with these engines. These cars are pose a safety risk to the driver and others on the road. They should all be recalled. Please let me know if you require any additional information from me.

In between oil changes, almost all oil will be burned off in none is added. There are no oil Leaks or other problems. This access oil consumption is a manufacturing defect.

The engine began to make a knocking noise. Upon our inspection, the vehicle had lost all oil. Vehicle was towed to our local dealership. Dealership informed us a bearing had become worn causing rapid oil loss and a rod to break, sending metal shards into the engine compartment. Engine could have seized up or caught on fire, had the vehicle continued to run. Dealership informed us of other Hyundai recalls for the same issue, however we were told our year/make/model was not included. Vehicle had been at same dealership 2 months prior for a heat/AC issue and a complete inspection was completed. No indication of bearing, oil, or engine issue was noted. No warning lights came on at any point.

Engine heating problems, electrical problems and now engine failure, the vehicle is no longer safe to drive. The vehicle is available for inspection. Other vehicles of same make, model, and year have been recalled for these issues however mine has not. I feel it has the same types of issues and safety concerns which should be recalled. The issues began with electrical problems inside the vehicle, random check engine lights coming on then off and other lights popping up in the dash board, the car was not accelerating properly, took the car in and they could not find a problem or fix it. The engine began heating and the speed of vehicle was also being affected. The car would randomly slow down quickly while on the highway at 70 MPH which happened a couple of times and was not safe at all, it could have caused a horrible accident. I could not accelerate enough to stay on the highway. That issue was fixed when we took the vehicle into the dealership to fix and should have been a recall as other cars where having the same issue. Hyundai should be held responsible for issues such as this that are affecting many other Hyundai Tucson drivers. Oil keeps depleting and the engine is burning through fast, also another concern and safety issue as that causes the engine to over heat and potentially cause a fire. A loud noise is coming from the vehicle, sounds like a helicopter it happened suddenly with no check engine light or warning. I'm concerned this car could catch fire, many Tucson's have had warning of catching fire. I don't park in our garage or even in the driveway for fear of that happening although they state ours is not supposed to be affected all these vehicle issues are telling me otherwise. Engine is now dead.This is unacceptable. Windows cannot be rolled down after multiple fixes that I paid for. Hyundai's poor production, manufacturing and quality control is unacceptable, please hold them responsible. Too much money has been spent on issues with no real results.

My Hyundai Tucson burns through 3.5 quarts of oil in 1,000 miles. I do not feel safe driving my vehicle. Yet I have no choice as Hyundai dealerships do not offer loaner cars and nurses cannot call off from the hospital with car problems. I purchased a Hyundai because of the 100,000 mile warranty, and I expect resolution in a timely manner. I have kept detailed records, including the 14 oil changes and two oil pan resealings required in the past year.

- Canton, MI, USA

Vehicle has 101k miles on it, just over the 100k Hyundai warranty. Vehicle began shaking and sputtering while driving, and check engine light illuminated, I was able to get it to a local mechanic. Mechanic said it had multiple codes (P300, P302, and P304). They did a compression test and said the engine has internal failure and should be replaced; quoted 13k to replace. I had it towed to the Hyundai dealership where I bought it, and they are investigating it. The service manager told me even with perfect maintenance records, Hyundai will likely deny a goodwill claim to replace the engine. Looking at all these engine failure complaints for this year model, it is clear this is an ongoing problem and Hyundai needs to issue a recall.

The engine has continuously thrown itself into limp mode, unable to exceed 2,000 RPMS and 60mph. It has been in and out of the dealership for the past 6 months as they have zero idea of what-??s going on. This all started a month after some software updates were done. Car had zero mechanical issues prior. Car has no audible knocking or engine failure symptoms. I-??ve spent atleast $2,000 out of pocket to attempt to get the car fixed with no luck. When I get the car back everytime, it goes into limp mode at interstate speeds which is extremely dangerous.

Vehicle began to consume large amounts of oil, needing oil added several times a week, every 200-300 miles. Vehicle is now needing engine replacement due to oil consumption related issues.

- Newnan, GA, USA

I was driving from California to Cincinnati to relocate for an unpaid internship. I had a mechanic check my car before I left and was told there was a problem with the engine since it was consuming more oil than normal. I took it to a dealership in California who then said there was nothing wrong and roping off the oil for the drive was expected. About 150 miles before Chicago, my engine started to sound like a helicopter. I had it towed to a dealership in the chicago suburbs that told me I had internal engine failure and it was a known problem so would submit it to the warranty company for me since I am the second owner and technically out of warranty. The warranty company made me jump through hoops to provide documentation for them of every oil change I-??ve ever had on the car, even from before I owned it, only to deny the claim due to being out of warranty. The first owner warranty would have still covered this incident as the car is only 7 years old and was just under 70k miles at the time. At time of incident, nothing on the dashboard lit up, not even the check engine light.

Prior to these oil changes and tires was completed and March 2023 engine light on and whining noise took it to Firestone twice they ran complete diagnosis twice and mechanic found no leak around the engine or leak in bottom and they recommended that I take it Hyundai dealership which I did that same month again Hyundai Service ran diagnosis and recommended replacing some air valve to fix the problem but the part needed to be ordered; again it took over six weeks to get appointment for service at this Hyundai Service dealership do said repair and I ask if I can still drive the car with engine light on they said it was o.k as long as engine light not was blinking. The next day engine light came on again and it took over six weeks to get appointment with Hyundai Service dealership in my area and the car sat in the driveway for over month. Now September 2023 same Hyundai Service ran engine diagnosis now need gasket and valve and they said engine failure because no oil in the engine and would cost $11K to replace. So please tell me in over month that car sat in driveway with no visible leaks in engine area and no leaks in the driveway, so where did the oil go and only answer I can deduce engine is defective.

My car has an engine oil leak that has been happening for over a year now since I bought it. I have to change my oil every 2,000 miles because of the leak, when Ive been told this car should be changing its oil for every 7,000 miles. My passenger door no longer opens from the outside once my car is unlocked. I have to put my window down in order to get inside and this is a safety hazard.
