had the oil consumption test done it failed and has been putting oil into the engine every 1000 miles or less due to engine burring up the oil had Hiley Hyundai due and oil change on 6/17/23 had to add 5qt of oil to engine on this day
Engine went through 5 qts of oil and had to refill on 8/31/23 had the oil changed by Hiley Hyundai on 6/17/23 they entered the wrong mileage during the engine consumption test
During travel on highway (~60 MPH), the vehicle suddenly lost power and the engine stopped functioning properly. The effect of the problem was that the vehicle began to 'buck' - as if the engine was having significant trouble running continuously. The engine light then illuminated solidly (not blinking). The vehicle slowed from lack of power and I was forced to move to the right lane/break-down lane through high speed highway traffic (NJ). I was able to travel /limp a few miles slowly to the next exit and get off the highway to a gas station. The engine ceased operation upon arrival to the gas station. The vehicle was towed to a mechanic who diagnosed the issue as engine failure. The vehicle was towed to a Hyundai dealership for diagnosis by the manufacturer (Denville, NJ). The diagnosis was 'engine failure'. No conditions existed prior to this event. In the recent past, the spark plugs and ignition coils were replaced. The vehicle had ~140,000 miles but it was used every day and was maintained very well during its life. I am the original owner. No insurance claim has been filed.

I was stopped at a red light. Once light turned green I went to make a left-hand turn. My vehicles power steering shorted out, almost causing me to hit a pedestrian and child.
2017 Hyundai Sonata with 108,600 miles, has experienced oil consumption/burning, since at least 85k miles. Costs outside of manufacturers recommendation: consumption report ($85) *Extensive engine cleaning ($500) -Hyundai considers 1 quart consumed per 1000 miles, acceptable. bearing clearance test ($140) **Engine replacement (reason for complaint, will cost $3880) Hyundai dealership most recently stickered oil change at 3,800 miles. At approximately 3,000 miles, the oil pressure light began to flash on/off. I checked the oil, it was low. I called the dealership to ask for advice. They indicated my car was OK to drive to the dealership (40 miles away), for service. On the way to the dealership, on the highway, my vehicle started to experience intense vibrations. My check engine light came on. I had to take my car from ~65 mph down to about 40 mph in a very short time, trying to maneuver in between semi-trucks, going from the left lane to the right shoulder. This was not safe, my engine could have seized. After this, my engine emits a loud knocking sound. Once I arrived, the dealership recorded 2 quarts of oil in the engine. After the oil change, the knocking sound still remained. They indicated they would not recommend driving the vehicle until they investigated the knocking sound. They performed the rod-bearing clearance test, and indicated it passed. With the knocking sound, their recommendation is to not drive the vehicle, and to replace the engine, ($3880 with many reductions in price). They've indicated Hyundai corporate would decline to replace the engine because the tests are not favorable for replacement. I've submitted an escalated case to Hyundai (HMA), to look into this. In short, they have declined to do anything because my VIN, year/model, do not qualify for any extended warranties, or recalls, to require anything to be done. The vehicle is not safe to drive. I've done all maintenance, and am left to suffer.
My car has been burning oil, i took it for service at the dealership and all they did was change the oil and tell me to come back in 1000 miles, and to do this 3 times, however before the 1000 miles while driving with other passengers in the car my engine started over heating, i had to pull over immediately, i checked the oil dipstick and it already showed below the LOW line, at this point i am assuming there is no oil left in the engine
I was traveling on [XXX] Baton Rouge La. and Gonzales La. at 70 mph when I lost power to my vehicle, an alarm sounded saying it was the Hybrid control system failure, putting my safety at risk as I had to maneuver off the interstate and onto the shoulder during heavy traffic. I called State Farm insurance to get my vehicle towed to Ralph Sellers Hyundai in Gonzales La. where it is being repaired.

In winter of 2018, my husband and I purchased a certified pre-owned 2017 Hyundai Sonata, and from the moment we drove it off the lot, it had an oil consumption problem. Then, in 2023, the spark plugs began failing. Each time this happens, the whole car shakes and stops running. We found out that Hyundai and Kia engines from 2009-2022 have major problems and that there are many class-action lawsuits against the manufacturer. We contacted both the dealer and Hyundai corporate to find out how we could fix the engine. We have small children and just wanted to repair our family car. The dealer refuses to fix it. They told us that it's Hyundai's problem. Hyundai acknowledged that we are eligible for a new engine but that until a certain rod fails and the whole engine implodes, they can't do anything about it. We have this in an email from corporate. We recently welcomed a new baby and had to buy another car because we felt this Sonata was not a safe choice to drive our children around. The solution to this problem should not be driving around in an unsafe car until it completely stops working. I'm hoping that the NHTSA can help me by sending out an inspector who can attest that this is a safety issue.

On February 27, 2023 we went to the Hyundai Dealer because our engine was leaking oil and we were told by Pep Boys that the Rear Main Seal was leaking. The Dealership scheduled us a service appointment three wks later, on March 23, 2023, when they replaced the valve cover gasket and the high pressure fuel pump gasket. On Jul 15, 2023, 2.5 months later, we return to dealership because our engine was leaking oil again and had leaked into the spark plugs tubes. They replaced the valve cover gasket again. Two weeks later on July 28, 2023, we went to the Dealership because the engine light turned on and the engine was misfiring while driving. They did nothing but added 3 quarts of oil because our oil was low despite us changing our oil 1 month prior (June 28, 2023). On September 25th, we returned to the dealership because our engine light turned on and our engine was violently shaking while making noise. At this point, we were frustrated and did not feel safe driving the car. We pleaded with the Service Manager to replace the engine from all the issues we have been experiencing including having to constantly add oil or change oil every 2.5 months. They held on to our car for 1 wk and gave us a rental. After inspecting our vehicle they replied that there was no engine issue detected so the Manufacturer will not replace the engine under the warranty. They only replaced the spark plugs and charged us with the service, parts & rental costs. It is now Monday, Dec 18, 2023, 1 wk before Christmas, and our engine light turned on once again while driving with our toddler in the vehicle. The engine not only misfired but did not allow us to accelerate beyond 30mph during high traffic hours on a road with a 50mph limit. The next service appointment available is 10 dys away, Dec 28, 2023, and they are asking us ~$400 to service the car. We feel helpless with the dealership/manufacturer, they are refusing to replace the engine. We fear that they are waiting for the warranty to expire.
First time I took my vehicle to the shop for over consuming oil they replaced the oil and cleaned all the parts. A few months after this my car would not accelerate properly and had a loud knocking noise in the engine and check engine light came on. After taking it to the dealer I was told I would need to replace the whole engine. I have proof of proper care done on the car but since I am second owner it is not covered in the original warranty. My car could have stalled and resulted in me and my family injured at the least. Hyundai knows about these issues and needs to recall the engines.
The vehicle has twice been disabled while driving due to -??lost communication with hybrid module powertrain control module.-?? This breakdown is a significant safety hazard as the car loses power and coasts to a stop without any warning. The second time was on a 65 mph highway. Neither time has had any warning before the malfunction lights appeared. The first time occurred on 10/7, and the vehicle was towed to the dealership. Nothing was done besides clearing the trouble codes and test driving with the car, which returned at the end of October-?"the second time the breakdown occurred about a month later on 12/3. This second time, I removed the code myself on the roadside so as not to be in more danger, and I am currently awaiting an update from the dealership-??s service department on their next steps after initially being told to just have it towed in again. Losing power without notice is incredibly concerning. I want to report this safety issue and determine my next steps to resolve it, as this has dramatically impacted my trust in the vehicle and its safety.
