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.

While driving on the highway, the car loss. The dashboard noted the Blindspot Detention System failed and the dash noted "Hybrid System Warning. Turn off Engine." The vehicle was towed to the dealership. They confirmed a Knock System Sensor had to be replaced. Less than a month after the repair, the same issue occurred on the highway again and the vehicle was towed to the dealership. Vehicle has been at the dealership for over 2 weeks and dealership has confirmed they haven't been able to accurately diagnosis the problem yet. Both incidents have occurred after the dealership addressed the recall campaign related to the engine.

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

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.

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.

I was driving down the freeway when my engine made a loud knocking noise, the noise got worse as the RPMs increased. The check engine light began to flash and I lost power, the vehicle will not exceed 60mph and vibrates when moving down the road. I believe this issue is widely know about and should be addressed and forced into a recall. I have maintained the vehicle and should not be responsible for a manufacturing error.

Excessive oil consumption. Engine makes knocking sound. Check engine light and/or oil light come off & on. Over heat light & HEV LIGHT. Bought car brand new in Sep2017. December 2017 car was in shop for a month. Ever since that incident, car has been in & out the dealership for same issues. Car has been serviced only by Hyundai dealerships.

We explained our situation to him (out of town, spending money on a hotel). They performed an engine electric Diag. which stated: Vehicle had multiple codes for low battery voltage. Test battery and got an instant failure. Cleared codes and test drove after new battery replacement. No codes came back. Approximately 1 hr. later in Jackson, GA we were on [XXX], middle lane & engine stalled (70mph & coasted over to side of highway). Received same code: Check Hybrid Battery System, !HEV, turn off engine. Had car towed to Kennesaw, GA. Rented car to drive home & had car towed to Alexandria, KY our home town. After 2 wks. car was put on diagnostic machine. Said they test drove car multiple times. They said could not duplicate the issue. It was suggested the next time we get code on our dashboard to take a picture of it or video. Took car to Kerry Hyundai, Florence. Test driven car 40 miles & have gotten nothing. No codes. Told them it was imperative that your mechanics find the issue. I will not drive the car as it is now. It is unsafe as it stands now. Breaking down 2x in GA. The first time after driving it 6.5 hrs. and the 2nd time after putting brand new battery in & breaking down exactly 1 hr. after driving. We have been without our car since [XXX]. Hyundai advertises a great warranty on their cars, one reason we purchased it. We wanted a SAFE, RELIABLE car since we are both retired and going to travel. We are out of $1,827.08 & afraid to drive car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
