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 federal safety agency can help me by sending out an inspector who can attest that this is a safety issue.

Excessive oil consumption Engine light stays on. Noise in Engine GDI 2.4
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.
The contact owns a 2017 Hyundai Sonata. The contact stated that after having an oil change, the engine seized. The contact stated that while driving at a slow speed, the engine seized. There was an abnormal knocking sound heard. After the failure, several unknown warning lights were illuminated on the instrument cluster. The vehicle was towed to the local dealer, where it was diagnosed that the engine had seized. There was a leak at the valve cover. Additionally, the crankshaft had seized. The vehicle was not repaired. The manufacturer was contacted and filed a case, but no assistance was provided. The failure mileage was approximately 165,051.
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.
I have a 2017 Hyundai Sonata I bought brand new. My car started burning oil where I was having to put oil every time I put gas which is weekly. I did the oil consumption test where I drove it 1000 miles 3 times and it burned 1.75qts, 2 qts, and 2.75 qts. They are saying it needs a new engine.
About a year ago during an extended freeway drive I noticed my engine started to sound different. I checked the oil and found it was a quart low which had never happened before. I filled the oil to its proper level and continued driving. About 100 miles later I decided to check the oil again and found it had used about 1/4 quart. Later my check engine light came on and it showed a code related to failed exhaust sensors. Since then I have had to check and fill the oil every 100 miles or so and now carry 5 quarts of oil in the trunk. I also noticed that my exhaust leaves an oil mark on the ground if I leave the engine running for a couple of minutes. I checked for oil leaks and didn't find any. My miles per gallon reading is also down. Seems to use most oil during freeway driving. I worry the engine could fail at any time and have been forced to restrict my driving to short local trips. I had the knock sensor installed per Hyundai's recall. Hyundai refuses to cover an oil consumption test.
My Hyundai engine is burning through oil like crazy. Only at 84,000 miles, and everytime I get my oil changed (every 3,000) it is completely dry. This is a known problem with Hyundai, and there needs to be a recall on these vehicles. It is costing me a fortune, and the risk of having my engine fail/catch on fire is not something I want to be worried about everytime I drive my vehicle. Something needs to happen to get this issue resolved.

Your date entry below does not allow for each of the 3 times in shop total roughly 85 days four months Would like Hyundai to buy car back as no trade in value now and I cannot afford more rental fees and repairs and the balance due of $495.75 from 1st rental. Car just entering 6 year when first issue started.
Was serviced by Hyundai in March 2023 to for oil sensor light but was really the oil was being burnt inside the engine Hyundai ran 2 oil consumption test in May 2023 and June 2023 which the car failed both. Service manger sent paperwork to Hyundai letting them know that engine was faulty because paperwork was summited with the wrong mileage the replacement of the engine has not happen. So Service manger has asked me to continue driving 1k miles and checking if engine is still burning oil which it still is I continue to write the service manger and sending pictures I can not drop my car off because we only have one car and they rarely have loaners and we are in bankruptcy so renting a car with a debt card is expensive trying to let people aware that this is a problem that Hyundai knows they have on these Sonata since 2015
Engine has a serious oil consumption problem. The engine has consumed 12 qts last 5,000 miles, or roughly burning 4 qts per 1,500 miles! Twice already it has rendered the engine dry despite frequent oil checks. Car also has routine oil changes every 3-5,000 miles. The safety concern is that the engine seizes in the middle of traffic. Also, because of the rapid nature of oil consumption, it requires travelling with emergency oil replacement supplies within the cabin. Fear is a collusion in the back (especially if stalled!) that could result in a fire, fueled by the supply of oil in the car. We keep at least a gallon (4 quarts), more if we are travelling anywhere more than an hour. We are a one car family and the safety issue is real. This is an ongoing problem since at least April of this year. Engine needs replacement.
The contact owns a 2017 Hyundai Sonata. The contact stated while driving 45 MPH, the instrument panel flashed and then the vehicle became inoperable. No warning light was illuminated. The vehicle was not able to restart and remained on the side of the road. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 149,000.
Persistent oil loss - requires constant refilling
Engine has been burring oil from the car went to get an oil change on 9-17-2023 last night engine light came on 10-04-23 there was no oil in the engine and dipstick was dry this has been happening now since March of 2023 Hyundai has been made aware of this problem by there own service team. The odometer read on the day of the oil change 9-17-23 131,571 miles last night when I add oil it was at 132,448 miles this is less than a 1k miles at 877 miles my engine burn 5.1 qts of oil.
Vehicle Safety Complaint - 2017 Hyundai Sonata Sport Engine Failure I am writing to report a safety concern regarding my 2017 Hyundai Sonata Sport, which I believe poses a risk to my safety and the safety of other road users. I have experienced the following issues with my vehicle: First Issue: Excessive oil consumption Must add a quart a week with minimal driving. Engine consumes an abundance of oil. Serious risk of internal engine damage & risk of the engine failure. Noticable oil covering spark plugs. I have to clean oil off the spark plugs weekly. Second Issue: Flashing check engine light Loss of power, engine stalling, misfiring, diminished ability to acclerate from a stop, and smelling gas. This is a traffic hazard, risk of life to occupants of vehicle, possible engine fire risk, and complete engine failure. Upon research, this is a MASS issue with owners of 2017 Hyundai Sonata's with a Theta II 2.4-liter engine. The Theta II 2.4-liter engine for Hyundai Sonata Hybrids has been recalled. However, Hyundai is very aware of the engine issue with non-hybrid 2017 Hyundai Sonata's. We have taken this to a AAA shop and the code issued was "catastrophic engine failure." I then took it too a Hyundai dealership and they said it was fine. I opened a case with Hyundai US and after months of back and forth, I get the same response, take it to the dealer. Frankly, I am getting nowhere with Hyundai. I feel they have recalled so many vehicles and their dealerships are so overwhelmed they are avoiding acknowledgement of this issue for non-hybrid models as long as possible putting the safety of Americans at risk. There a millions of consumers who have put their faith in the safety of Hyundai's engine for my make and model with this Theta II 2.4-Liter engine. Hyundai is 100% aware of these issues and hasn't issued a recall. Dealerships are flooded with vehicles and wait lists are long. American families need safe and reliable transportation.
While driving the vehicle on the highway, the check engine light began flashing and the car immediately lost almost all power. We had enough power to pull off of the highway off-ramp where the vehicle began jolting before stalling on a side road. We started the car back up and had just enough power to drive into the hospital parking lot next to the side road, where we had it towed to the Hyundai dealer across the highway. That Hyundai dealer identified the Intake Manifold Runner as the culprit via engine fault code P200A00. This Hyundai dealer was also concerned with oil consumption as the car's oil was low even though it had been maintained according to Hyundai standards. They did an oil consumption test, but argued that it was normal, while refusing to repair or replace the Intake Manifold Runner, & only cleaned the Intake Manifold Runner, for which they charged. They gave us the car back and it continued to consume oil to the point where the dipstick was reading below the low line. The car also continued to jolt and have low power. This same Hyundai dealer told us to add oil to the engine and have it towed to them, which we did. They then claimed the car had too much oil, blamed us for it, and continued to refuse to investigate the issue any further. They gave us the car back after a lot of confrontational back and forth on their part where they agreed to change the oil and do another oil consumption test at no charge. A few weeks later, the check engine light came back on, the car lost power, and we called the same dealer back. The dealer refused to help us, so we took it to another dealer who found the same P200A00 fault code and replaced the entire Intake Manifold Runner under warranty without any questions asked, and at no charge. When we were still dealing with the first Hyundai dealer, we opened a case on them through Hyundai corporate, but corporate did nothing and did not care about the issue. Hyundai Corporate and one of their dealers ignored 21-EM-008H.
The hybrid system failure. Chrck engine light is flashing. Abs system failure. Battery failure. Car can't go over 45mph, lost a job because of the issues. I'm afraid the car is going to blow up or catch fire. I'm afraid to drive it. The acceleration is barely there. It's like the car doesn't even wanna go. It sucks through gas like no other.
The car is consuming excessive amounts of oil. The engine has a knocking, tapping sound. Found out today the intake manifold is bad, which we all know is a very bad thing to go wrong. The engine has a very bad misfire. The car only has 53k miles. I own an 09 Sonata with 154k and I have never had a problem. This is why I continued with Hyundai. Also, the steering seems to tense up regularly. I am very worried about driving this vehicle. I have read hundreds of complaints regarding the excessive oil consumption. I feel you need to express the importance of these concerns to Hyundai
I own a 2017 Hyundai sonata base, I got the car at around 168k miles and it’s now sitting at around 180k the car burns oil like crazy, I had taken it to the Hyundai dealership in Gaithersburg, MD and they declined the oil consumption test under warranty since the extended warranty is only until 150k, then they tell me if my engine seized and was towed to a local dealer only then they would likely replace it due to its failure. That the engine would only be covered if it seized. This makes me nervous due to it could seize at any time or place, when I start my car I can hear a bad bearing and then it goes away after oil has been started to be moved around the engine more, a few seconds after starting the car. At last gave another call and same answer, if it siezed they believe Hyundai would replace it. Even when the oil is low no oil light appears, so I have to check it almost every time I go to drive as a full time student and full time employee this issue is really annoying. I just hope it if siezes it’s covered and I can get a rental to make it to work and university.
The oil is leaking into the engine. My catalytic converter has failed as a result of the oil consumption issue.
Burning over a quart of oil every 500 miles.
The contact owns a 2017 Hyundai Sonata. The contact stated while driving 45 MPH, the vehicle started shaking violently. The contact pulled over to the side of the roadway and inspected the vehicle. Upon inspecting the vehicle, the contact became aware that the engine oil level was extremely low, even though the vehicle had recently received an oil change three weeks prior to the failure. The contact stated that the vehicle was consuming an excessive amount of engine oil. The check engine warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 160,000.
The engine has started to burn oil from the inside of the motor was first noticed May 8th after the oil sending unit was replaced on the March 17th 2023 I thought it was faulty took to the dealership and all the oil had burned out in it. Dealership filled it up went about 1k miles and the oil light came on again too it back to the dealership they decide to do 2 oil composition test on the car. The care failed both times and under the 1k mile mark. Told Hyundai about and put in a claim they entered the wrong mileage on my car so it was denied for recall. I was told to continue to keep just adding oil for every 1k miles I have done this since July 1st 2023 and still is doing it an the engine keeps just burring the oil in the engine
I have been notified in the last three oil changes to my 2017 Hyundai Sonata that it's missing oil. Today, I went to an oil change even before the oil change was due (the car noted it was not due for another 819 miles or 3 days). There, they told me the car has an engine oil leakage and that it barely had engine oil. I told them, the car didn't even light up as needing oil. They told me to visit a local Hyundai dealer to have it checked ASAP, as they have serviced various Hyundai Sonata and Elantra models with the same issue.
HEV light comes on and the car starts slowing down & beeping. Unsure what the issue is but this started once the car had more than 100k miles on it
The car has an oil consumption problem as noted by dealership when following through with oil consumption test. The car has had several instances of stalling upon starting , car shakes and has no power. Yesterday I was 50 miles from home and car attempted to stall and it was 105 degrees outside. I am becoming afraid of this car. No, thankfully no fatalities at this time or I would not be sending in a claim if I were a fatality. There has been no attempt to fix the car which is still under warranty. Is the warranty not valid? One reason to buy the vehicle was for the warranty. I have records for oil consumption test.
On July 13, 3023, I was driving the vehicle and the pwwer steering light illuminated, but the light did go out. I took the vehicle to Stew Hansen Hyundai in Urbandale, Iowa, indicated the entire power steering column has got to be replaced. The parts hace been on back order, and as of today, August 16, the service center is still waiting for the parts to be delivered. The vehicle has slightly over 69,000 miles and 6 years. It's not covered under the warranty, Because that part is covered by the 5 year 50,000 warranty, so I have to pay an estimated $3,400. hundred dollars. I did share with the service agent that I received a power steering 15 years, 150,000 warranty extension notification, and provided him a copy, but waa told that was only for a specific part, and it did not apply to my repair, because my repair is for the entire power steering column. The reason why I'm paying this is because in June 2022, at 60,000 miles the vehicle's engine had to be replaced. That too took over two months to be fixed and returned to me, but repair as covered under warranty. Also, I'd be happy to share the information, but my vehicle is still in the shop for repair, depending on when the parts are received.
