ENGINE
My car continues to consume oil and it’s always low. There is no leak. I have been told that the engine is constantly consuming the oil. I have taken it to the dealership and they submitted a form but nothing came about it. This is a safety concern for how fast the oil is being consumed

POWER TRAIN
Starter replaced at less than 50,000 miles. Normally a starter will last 150,000 miles or more. I was past the warranty by 9 months but was under the mileage. Warranty was 5 years or 50,000 miles. Hyundai parts are cheap and do not last long compared to other companies.

ELECTRICAL SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS
I was driving on the freeway and my car lost all power. My indicator dash board flashed lights and a loud beeping sound. The warning lights flashed to check my hybrid system and turn engine off, HEV. My car immediately lost power and turned off. I was on the freeway, I almost got into an accident, cars were honking at me. My vehicle was towed by my insurance company. I receieved a phone call from the service advisor today, he informed me that I need an electical water pump and the cost quoted to me is $1908.00. When I complained to the advisor he told me that water pumps only last 3-5 years. I told him that my previous car was a 2013 Sonata and sold it with 100,000 miles and I never had water pump issues. My online research discovered that this has been a recurrent issue with 2018 Sonata's.

ENGINE, ELECTRICAL SYSTEM
We were heading to Lakewood NJ from Bucks County (North of Philly) . Car trouble w/ hybrid system on Rt 1, just past I-95. Got off @ Fairless Hills & took back roads. We could only go 20-30 mph. IDK how many times I pulled over. Several lights on, including "Check hybrid system. Turn Engine off", engine light, low tire pressure, battery & 3 other unidentifiable lights. I turned around to try to make it home, as 2 years ago, I had a similar issue, which turned out to be the hybrid water pump failed. We finally stopped near a park & called AAA & towed to dealer. Prior to driving, we had no fluid on our driveway. My last synthetic oil change was April 19, 2023 @ 49,097mile. I now have about 57,000 miles. Today, dealer said no oil in the car & oil pan was all wet. They claim the oil filer was loose. Why would it take 8 months to loosen to lose oil? After adding oil & taking for test drive, they said the engine seized & would need to be replaced. Not under warranty. Add to complaint - the remaining dashboard lights where checked and non of them was for the oil pressure. If I lost enough oil for the engine to seize I would expect a low oil pressure light to come. The dealer informed me on Dec 26, 2023 that when doing the diagnostic, the oil pressure light came on for them. The photos attached to the case does not show the oil pressure light on.

Oil pan crack. Leaking oil can get on engine or underbody components causing fire or failure of breaking systems causing an accident resulting in death. Problem was identified by dealer and in fact the dealer rep said this was common. It has not been inspected by police or insurance reps. There is no warning systems in place for a cracked pan.

I own a 2018 Hyundai Sonata SEL. I purchased the car in 2020 with ~17,000 miles on it. At ~50,000 miles the engine begin burning oil. It has progressively gotten worse. I can’t bring myself to have anyone drive my car because of this issue. It is all to likely that the result of the car burning so much oil in a short period of time. That it can pose a serious risk to anyone driving the car if the oil wasn’t checked. This is not a common problem with many cars, this is a problem with Hyundai vehicles. The negligence of not issuing a recall for this is horrible. I have taken my car to private mechanics and Hyundai service centers. The response I get is “oh yeah they’re know for burning oil and there’s not much to do about it.” That’s a ridiculous response to situation like this for the thousands of owners. How long will it take to issue a recall, until a life is taken? When the issue could have been fixed by issuing a recall. Complete negligence on Hyundai and the NHTSA.

ENGINE
Purchased this vehicle with about 64K miles. Vehicle, as per CarFax report, has been meticulously maintained. Upon delivery, we changed the oil and filter with full-synthetic Amsoil. We ensured oil levels were appropriate prior to returning to service. No more than 1,000 miles later, roughly incurred in about a month, we checked oil levels again. This time, it required about 1.25 quarts to return it to the appropriate level .We did research and apparently, there is a class-action lawsuit filed by owners of Hyundai vehicles with this specific engine, the Theta II 2.4L 4-cylinder engine. Here's an article making reference to apparently your organization already looking into these complaints. [XXX] Could you please advise if the NHTSA will take the necessary steps to request Hyundai to issue a recall? I have found multiple articles where Hyundai is rejecting to take any action on their own, in most cases, advising their customers that such level of oil consumption is 'normal'. That clearly contradicts their own owner's manual guidelines. I own a 2001 Chevrolet Suburban 1500LT with 302K miles and the vehicle will go nearly 5K miles between oil changes while requiring no more than 1/2 quart of oil to keep it at the appropriate levels. I also own a 2019 Honda Accord 2.0T that normally requires oil changes every 10K miles and it seldom requires more than 1/8 of a quart to keep at the appropriate oil levels. There is definitely something definitely wrong with this engine type and requires governmental involvement to hold the manufacturer to provide adequate remediation. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
My 2018 Hyundai Sonata began running low on oil around May 2022 when the car had 86,400 miles on it. I informed the local dealership where I bought the car and had all maintenance completed. The dealership and myself contacted Hyundai Corp. Hyundai Corp approved oil consumption testing which resulted in an induction cleaning in Sept. 2022. This did not resolve the oil burning issue. The dealership service staff informed me that I was given a lifetime warranty on the engine and to keep driving it and putting oil in as needed until the engine failed and then to bring it to the dealership for replacement engine. There evidently was not a fix for the problem. Most recently I have been putting oil in the car every Sunday. I sent an email message to Hyundai Corp about a month ago to request to talk with a case manager regarding this excessive oil issue. In the meantime I have taken my car to the dealership for all suggested maintenance and informed them of the continued oil consumption. Before I received a response from Hyundai, my engine failed. I pulled out of my drive way and my car was stalling and would not accelerate properly then my engine light came on. I drove the car about a quarter mile down the road and turned around and came home in this very scary condition. This is a safety issue due to pulling out on a road with no power to accelerate. I had it towed to the dealership. I was give a case manager from Hyundai. My car has burnt valves and excessive carbon build up from excessive oil burning. Hyundai will not cover engine replacement costs, or buy back the vehicle. This vehicle is available for inspection. I'm not sure if I should leave it at dealership or have it towed home.

ENGINE
I was driving and when I made a left turn I heard a sucking type of noise coming from the engine. I immediately made an appointment at my local Hyundai dealership, however they were booked for another month so I made it at my local mechanic shop. After inspection by the mechanic I was told and confirmed that the noise was a result of having barely ANY OIL LEFT IN MY ENGINE!!! Because the oil pan had a hairline crack in it and had leaked the oil out. My check engine light had never come on through this process. This is so dangerous because my engine could have eventually seized while being in traffic with potential harm to both myself, people in my car and other vehicle traffic!!! Also, WHO KNOWS HOW MUCH DAMAGE WAS DONE TO MY ENGINE AS A RESULT OF THIS!!! My engine can be ruined!!!

UNKNOWN OR OTHER
For now the fifth time in the last 16 months the HEV light and engine light has lit up while the car jerks and sputters and dies. Below is the incident report that I filed on or about August 8, 2022. Again at the end of the day yesterday on October 20, 2023 the same issues still arise for the fifth time. See below for a re-cap of the issues I am once again experiencing after Hyundai claims to have fixed the issues: For the fourth time the HEV light (and others) has come on and the dash has lit up while I was driving, with the last three times leaving us stranded in dangerous road situations with little or no power. The light first came on in July 2020 at 40,089 miles. A dealership reset the codes and I had no problems until June 7, 2022 when the lights lit up on the dash again and the car died and I had to have it towed to a local dealership. They could find nothing wrong with it and checked all the wiring and said none of the codes were coming up and that the car ran fine for them when test driving a day or two after I had it towed. So they released the car back to me deeming it good to go. Then only 19 days later on June 26, 2022 the HEV light among other lit up again and the dash indicated to pull over and cut the car off due to the hybrid system. I had it towed to the nearest dealership again. The then looked at it and said they reset all the codes and everything looked to be good to go. Then AGAIN on Aug 8, 2022 (3rd time in two months), we were put in a dangerous situation trying to get the car off a busy highway when the HEV light (and others) again lit up the dash and our power went almost completely out while the engine jerked violently as we tried to avoid being hit by cars while trying to get off the highway before it completely died on us. Four times now Hyundai dealers have shrugged this off saying "we reset the codes" and we can't find an issue. We have been put in dangerous traffic conditions three of these times.
