ENGINE
Me along with thousands of others are experiencing the “excessive oil consumption” issue. Hyundai is doing nothing except making us pay tons of money for testing when they already know what the issue is and is refusing to do anything. Enough is enough. I can’t afford a new car nor should I be forced into buying one. The dealerships have been instructed by Hyundai USA not to admit negligence or helping g the car owners.

ENGINE, UNKNOWN OR OTHER
This is the seventh occurrence of complete loss of power while driving on the interstate. The hybrid system warning activated, followed by the engine shutting down, and all dashboard lights illuminated with alerts indicating "Shut Off Engine/HEV." An 18 wheeler was pulling out from the shoulder as I was losing power and barely missed getting crushed. The former problems have all been at interstate speeds with similar accident avoided. The service history clearly demonstrates that Hyundai has repeatedly attempted to address this issue by replacing numerous critical components, including the engine, transmission, knock sensor, battery (three times), integrated brake actuation system, and smart cruise control, among others. Despite these extensive repairs, the problem persists. On this latest occasion, less than 4,000 miles and four months since the last major incident, the dealership has proposed replacing the intake manifold, EGR valve, HSG belt, and spark plugs. The belt was changed less than 20K miles ago. and I believe the spark plugs were as well. Each time my vehicle experiences this issue, it is out of commission for weeks or even months at a time, causing significant inconvenience and raising serious safety concerns. I no longer trust this vehicle and I don't believe the many recalls have successfully addressed the root cause of issues with the 2017 Hybrids.

I had the engine replaced in Feb of 2024 which was covered by the engine replacement recall. In May of 2024 I started having issues with my check engine light flashing on then off. The engine will lose power briefly during this time and the engine shakes. It feels like you are going to lose control of the vehicle when this happens. This has happened approximately 3 times at freeway speeds and a total of approximately 15 times total. I have taken it to the dealership 3 times for this issue. They made us pay for spark plugs that were fine when the engine was replaced (3800 miles was driven between the engine replacement and this issue starting). The dealership has now had the vehicle since the middle of May said they can’t recreate the problem but are saying it is a fuel pump. This was also fine when the checked it when the engine was replaced.

Apparently there has been a leak in the engine and was not retaining any oil. We’ve tried to fixed it but it wasn’t fixed properly. My safety and others were at risk by the car shutting down at any moment. I have not taken it to the dealer yet. I am willing to do an inspection at a dealership for a better understanding on the issue.Check engine light came on about a month ago and I kept trying to fix it but check engine light is still there.

Without warning my car started consuming oil while still under manufacturer warranty. Hyundai had me do 2 oil consumption tests and they did there so called engine cleaning which they said should fix the problem on 2 different occasions and not even 3 months apart, well the engine was still consuming oil and now the oil is messing up my spark plugs and Hyundai refused to fix it. There is enough evidence out there that shows Hyundai knows their piston rings in the engines were no good for years and still keeps selling these engines without warning the customer. Hyundai refused to honor their warranty on the engine cleaning solution that the dealership is required to use by Hyundai itself. My car's engine went in less than 7 months after they first started doing the oil consumption test on my car and now refuse to fix or replace the engine. When my car's engine went luckily I was on a side street when it went, because if I was on the highway who knows what could have happened. Hyundai omitted in lawsuits outside the country for knowing these were bad piston rings. Which also led to fires in these cars engines. There is a Facebook page with thousands of people having the same issue and Hyundai not even trying to fix the problem, and there our to many to count around the world with the same engines and cars having the same issue so it not just a small isolated event.

The motor in this vehicle consumes oil like a drunken sailor consumes alcohol. I have the oil changed, and before the next scheduled oil change, the car had The oil indicator light come on. I immediately went to the nearest AutoZone and purchased oil and put in the car. I took it to the dealership and they told me they were aware of the issue surrounding the motor in this make and model of vehicle however, my Vin number was not included on the recall. So they could do nothing to help me. This is a safety issue because the motor should go at least 3000 miles with without having to have, a full 5 quarts of oil put back in because it’s sitting on empty. I have been dealing with this for over a year with the local dealership and with Hyundai USA to no avail

EGR cooler leaks and slowly burns off engine coolant resulting in the car overheating while driving, forcing a quick exit from the road, or stopping in traffic not to damage the engine. Google search shows this is a very common issue with these hybrids.

A light on the dash went on and we were told it was the airbag clock spring steering column. At cost of over $900 we had to have it repaired. There were previous recalls on the Hyundai sonatas for this part and I think it should be covered. The car has only 60,000 miles on it

Have problem with high oil consumption which caused carbon deposits to burn valves. I was driving on the highway when engine light came on the car lost power and stalled on the road. At highway speeds that could have caused a collision with traffic. The car was bought at a dealer with 35000 miles on it when I started to notice a slight problem. The car now has 88500 miles on it and has gotten worse. The dealer said it needs a new engine which Hyundai has denied. The dealer said too many mile’s between oil changes but all maintenance has been done when needed at the dealer and Big-O. I have noticed online many complaints with the same problem. I contacted Hyundai have case #23502874 Cost to repair $9743.94 at dealer

While driving on the highway the car stopped .. it was towed to Hyundai as it is still under warranty and ultimately we were told it suffered "catastrophic engine failure" I was also told that a new engine would not be covered. When I asked why I was instructed to give maintenance records which I did. It was denied BEFORE they asked for records. I have been going back and forth with Hyundai and the reason they have given me is an exact effect of their ongoing issues with the THETA II- GDI engine. I have compiled so much research regarding the defect and Hyundai stopped responding to me when I asked them the difference between my car's engine and those that Hyundai knowing delayed recalling and the thousands of same engines that have determined as defective. This has been going on for months and I am not going to let it go and there is a growing petition for another investigation to be opened. Hyundai deliberately delayed recalling a known defect that has affected thousands of vehicles and it is shameful they are playing games. I have an enormous file of data that would indicate the 2017 Sonata Theta II is just as defective as all the others and that their own mechanics have gone on the record admitting that an oil blockage from metal shavings will ultimately cause a catastrophic failure. I have emails from Hyundai and Texts from dealer on cost. I am checking with my attorney to see if they can be shared.

STRUCTURE:BODY
The cap on the shark fin antenna came loose in normal service and cannot be secured. If this part were to fly off at highway speeds it would pose a safety issue to following vehicles since it becomes a projectile capable of causing significant damage. This problem is similar to that documented in KIA TSB SA272 which Hyundai does not recognize, although both manufacturers share similar component designs.
