2018 Hyundai Sonata complaints

The vehicle is disposing oil really fast every 3 weeks I put 2 quarts in. A whole lot of dark smoke comes out when the car is 1st cranked up. Oil light flases constantly off and on in like a second. You would miss it if you blink twice. At least it should stay on to warn you of that their is no oil in the vehicle. Check the oil stick, bone dry. No leaks, no cracks, I took it to the shop and the repairs is really a 1 new motor

The engine of my 2018 Hyundai Sonata has been losing oil at a significant rate. By the time I take my car in for a regular oil change the oil is either completely out or nearly out. I contacted Hyundai regarding an oil consumption test which is what was recommended to me by Hyundai corporate when I called to report the problem. Hyundai has completed the oil consumption test and although they stated that it is consuming oil at a higher than normal rate, it still meets their “standard” and the recommendation that they have was to fill up my oil every time I put gas in my car which is an unreasonable expectation . The safety risk is significant. Although Hyundai recognizes this is an issue, they have said that there is nothing they can do. For a vehicle that has only 79,000 miles on it, there is no indication of where the oil is leaking to. During my last oil change, valvoline stated that this is a known issue and that the oil leaks into the engine of the vehicle. Hyundai inspected the vehicle and again stated that although it is burning oil off at a higher than normal rate, their standards state that it is not burning off enough to warrant an engine repair. The oil warning light did appear just before my last oil change which was approximately January 2024. When the light came on, I immediately scheduled an oil change and that is when I was first made aware that this was a known issue with certain Hyundai models

Severe oil leak into the oil pan has required frequent maintenance to keep oil in the car.

I own a 2018 Hyundai Sonata 2.0 turbo I paid cash for it in [XXX] with 2011 miles on it for 24,000 cash didn’t start having problems until 2022 then the I kept hearing a knocking on the left front wheel. I had it look at several places because the Hyundai of Louisville dealership kept telling me my title was branded I didn’t know what that meant till I took my title to the tag office and had the sheriffs department check the title out and it was an still is 100 % clean then my engine kept getting worse an in may of 2023 the engine stopped working I had the car towed to the local dealership and they couldn’t even look at it till Aug of 2023 the they told me I shot out a code 99 and they refused to update my software for the knock sensor system and wouldn’t honor the regular 60,000 miles warranty my car only had 48,000 miles on it . They didn’t bother telling me about the faulty GDI 2.0 turbo engine in August of 2023 I had to research it and find out on the internet that it’s a excessive oil consumption problem with this faulty engine. I had my car stolen for 6 days in April of 2023 and everything was taken out of my glove box an trunk . My oil change receipts were kept in an envelope in the glove box and were stolen with all my car registration an insurance papers . So the dealership refused my free engine replacement because I don’t have all my oil change receipts and blamed me for the oil being out of the engine which is due to the faulty GDI 2.0 turbo engine the dealership

I have an oil leak. After getting an oil change I have to add 1-2 quarts of oil before my next oil change. I do have my oil change as recommended. This has happened so far on the last 3 oil changes I’ve done.

Car continues to burn oil within a week of getting oil changes, the oil will be black and it will be low sometimes there will be no oil and there is not an oil leak. Right now we had to pay for a combustion test and have to drive 1,000 miles then check the oil at Hyundai again and already our oil is starting to burn and is low. Hyundai said if the combustion test comes back still burnt or low Hyundai would give me a new engine and yea it’s low and already a tint dark not as dark as it used to get but still it’s low with no leak and we did not get the promised new engine after paying almost 600$ for the test… Also electrical wise the computer randomly sounds like static when Siri talks also the music does not play and randomly the maps will close out we have tried new cords we have tried everything and it still happens.

On [XXX] I was driving on [XXX] [XXX] from Rockville, Maryland when my vehicle (2018 Hyundai Sonata Limited) started to lose power and control and all dash lights started to show. I was able to move the vehicle to the highway shoulder before all power and control failed. Had I been moving at a higher speed or in heavier traffic, or been slower to react this could have led to a catastrophic incident. When the roadside assistance showed up they found that my alternator had completely detached from my vehicle. The vehicle was towed to the Sheehy Hyundai dealership in Waldorf, MD and examined on [XXX]. The maintenance staff informed me that there were 3 other similar cases they're working on, and that there is a flaw in the design of the alternator bracket using aluminum materials that failed, and that they've reported this systemic issue to the manufacturer but have yet to receive any indications that this would be considered for a recall despite the catastrophic impact this could have.

The car was sitting in the parking lot and randomly black smoke started coming from it and then it turned into fire within in minutes. No one was in the vehicle and 911 was contacted.

Vehicle 1 operating normally in traffic on [XXX] in Westfield MA. Operator 1 notices alert on dashboard. As Operator 1 looks down briefly and returns eyes immediately to the road, she sees Vehicle 2 braking to slow or stop. Operator 1 depresses brakes, but vehicle does not slow as it usually does, nor does Automatic Emergency Braking engage as it always has in the past. Front of Vehicle 1 makes contact with rear of Vehicle 2. Dashcam footage appears like brakes did not activate at all, either manually or automatically. Vehicle 1 airbags deploy. Westfield Police respond, as well as Westfield Fire, who cut the battery cable. Vehicle towed to Interstate Towing, Inc. Yard 5, 20 Clifton St, Westfield, Ma 01085. (413) 593-1900 interstatetowing.com. Owner 1 viewed vehicle at tow yard, and noted that the battery was completely melted, with only portions of the plastic casing along with internal plates visible. Much of the plastic and rubber components immediately adjacent to battery location were melted and deformed. As a layperson, it almost appears as though the battery was in the process of shorting out just prior to the collision, possibly rendering many of the safety systems inoperable.

Car would not start. Odor of burning wires coming from the engine compartment with a little smoke. Had car towed to the Dealer who replaced the starter. Ok for two weeks then same thing. No Start and an odor of burning wires coming from the engine compartment. Had it towed to the Dealer again where it sits today.

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

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.

I have had a new engine put in my Sonata back at the beginning of 2023. For the past two days my car will jerk really hard, and then loose power not accelerating over 25 rpms and my check engine lights comes on when it jerks really hard.

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.

The contact owns a 2018 Hyundai Sonata. The contact stated while driving approximately 35 MPH, the vehicle jerked and failed to accelerate as designed. The contact stated that the check engine warning light was illuminated. The contact drove the vehicle to the residence and then contacted the dealer. The vehicle was diagnosed but was not repaired due to the cost. The manufacturer was made aware of the failure. The failure mileage was approximately 83,920.

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.

The paint if pealing off in large sections due to a manufacturer defect in the primer. The flakes can fly onto the windshields of other vehicles causing collisions.

The contact owns a 2018 Hyundai Sonata. The contact stated that the vehicle failed to start in cold weather, below 50 degrees Fahrenheit. The contact stated that the vehicle would start as needed whenever the weather was warmer. The vehicle was taken to an independent mechanic, where it was diagnosed; however, the cause of the failure could not be determined. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 72,000.

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.

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 req

The contact owns a 2018 Hyundai Sonata. The contact stated while driving 70 MPH, the vehicle went into LIMP Mode and lost motive power. The contact was able to pull to the side of the roadway, where the vehicle failed to restart. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who determined that cylinder #1 was misfiring on every cycle due to damage to the piston. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 107,000.

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

Warning lights keep coming on for ABS and Blind Spot Detection. Please help as I know this has been recalled in other 2018 Sonatas. So why is my VIN # not included in these recent recalls?? I FEAR for mine and my daughter's safety as she turned 16 in February 2023 and started driving this car in August 2023. PLEASE HELP!!

The drivers seat operation is going berserk. I can not get it to move at times and at other times it only partially operates. It also may do the opposite of what control direction I move it! I had to drive home today not being able to to the gas pedal well...very dangerous.

Engine is failing, stalls frequently. Dealership where I bought the car will not help, other dealership advised us to drive the car until the engine fails. I do not feel safe driving this car with my children.

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!!!

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 situat

The contact owns a 2018 Hyundai Sonata. The contact stated while driving 65 MPH uphill, the vehicle shuddered. The check engine warning light and low oil pressure warning light were illuminated. The contact was able to pull to the side of the road and turned off the vehicle. The vehicle was towed to an independent mechanic, where an oil change was performed, and the spark plugs were replaced. The vehicle was repaired. The contact related the failure to NHTSA Action Number: DP22003 (Engine). The dealer was notified of the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 77,347.

My car is misfiring, hesitating accelerating, severely shaking and vibrating which you can feel in the pedals and steering wheel, and the check engine light is on. This issue has been ongoing for over a week already. When the engine light first came on on 9/7, i pulled over on the side of the road and had a mobile mechanic check it out. The code was coming up as a bad ignition coil in cylinder 1. When he took out the coil and spark plugs, he saw scoring on the spark plug from oil as well as oil being consumed in the cylinder itself which has been causing my vehicle to misfire. The mobile mechanic stated on his invoice that I need a new engine. I took my car to Faulkner Hyundai on 9/11 and they said the best they can do is an oil consumption test even though they personally know I need an engine as well. I have not been able to drive the vehicle due to the ongoing issues, I am afraid for my life and safety that god forbid the car stalls out on the highway while I am traveling to or from work I could get into a major accident. They are putting my life in jeopardy.

The contact owns a 2018 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to an independent mechanic, who retrieved DTC Code: P1326 and related the failure to Technical Service Bulletin: 20-01-024H-1 (Theta GDI Engine DTC P1326 - Engine Inspection / Replacement); however, the vehicle was not covered under the TSB. The vehicle was not repaired. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 59,000.

The contact owns a 2018 Hyundai Sonata. The contact stated that while driving approximately 60 MPH the vehicle suddenly began sputtering and then completely stalled. The contact had to coast to the side of the road and noticed the check engine light illuminated. After approximately 10 minutes, the vehicle was able to restart. When starting the vehicle there would be a sputtering followed by the vehicle shutting off. The failure began to occur while idle as well. The contact stated that while attempting to reverse out of a parking spot the vehicle suddenly accelerated forward instead. As a result, the vehicle ended up crashing into a concrete light post. The air bags did not deploy. There were no injuries or medical attention needed. The vehicle was able to be driven after. No police report was filed. The vehicle had been towed to the dealer who had stated that the starter relay issue may be the cause, however, because of not being able to duplicate the failure they were unable to give an official diagnosis. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 86,000.

UNKNOWN. I noticed that there was a check engine light on and I took it to autozone to have it checked out, they told me that it was coming back with the code of an o2 sensor. I thought nothing of it until it started not wanting to start right. On July 1, 2023 I took my car in to the dealership for an oil change and they never said anything about why my car was doing a delayed start. It would eventually start but it took at least a minute. I bought a new battery from walmart to put in my car so that it would not do the delayed start, but it kept doing it anyway. Finally decided to take it to a mechanic and the first time that he started it took at least a minute, he realized that he didn't have his computer (code reader) with him so he turned it off. When he returned with the code reader he plugged it in and started the car then it started smoking, smoking turned into fire that caused the entire underside of my hood to melt including engine, electrical harness, belts, battery and much more. If it wasn't for the mechanic's quick thinking by putting out the fire while calling 9-1-1, the fire would have gone to the fuel tank and exploded. Yes, the safety of others was put at risk.

Oil leaking, replaced gaskets Oil continues to burn at a fast rate. Putting up to 6qt oil extra every month. Oil changes have been regular. Dealership only cleaned engine and told me that was all they could do.

Car consumes TOO much oil. Even after I get an oil change I have to add more oil weeks later and the oil is always black. Several times the sensor has gone out on me on the hwy and I’m not able to accelerate or go over 35 miles which is extremely dangerous .

This vehicle consumes one quart of oil every 1000 miles. I have documentation to prove it. Hyundai has done their own asessments and claimed that it consumes less. There was a class action lawsuit filed in California for this issue.

My engine was burning oil, I was/ am up to date with my oil changes. The oil suddenly kept being dirty. My car broke down twice. One time oil was shooting out of the top of my engine and it was smoking. Hyundai claimed it was neglect and only accepted my paper copy of oil changes but not the ones on my debit card statement.

The Kumho 205/65 R16 treads are losing chucks of rubber on 3 tires with just under 17000 miles as of this date 7/24/23 and under 6 years old. ( their warranty states 60K or 6 yrs) Kumho will not warrant the tires in any way shape or form. Have tried to get some help from them since Jan of this year (2023) with no results. Also the service dept at the dealership tried to get me help but was not successful. Even after taking many pictures and information and sending them to Kumho. No help.

I first reported issues with my vehicle to a local Hyundai dealer January 16, 2023. I was advised I couldn’t get an appointment until March 8, 2023. Since March 8, 2023 I have taken my car to the dealer my numerous times for a series of testing over the course of 3 months. I was advised my car was burning too much oil of oil per 1000 miles. I was also advised that the transvalve and engine needed to be inspected by an adjuster to determine a faulty engine in order to get approval from the manufacturer. My car was at the dealer for almost a week. On June 15, 2023 the Hyundai dealership advised the engine was faulty. I was also advised warranty approved for a new engine due to faulty engine/oil consumption. I was advised to pick up my vehicle from the dealership. On June 16, 2023 I picked up my vehicle. I was told by the dealership to keep driving my vehicle until the new engine came in due. I was denied a loaner/rental at the time even though they knew the car had a faulty engine. Immediately after leaving the dealership dealership my car started smoking. I pulled over immediately got out. The car caught on fire and burst into flames. This was a very dangerous safety risk. It caused panic attacks, anxiety, headaches, and lots of sleepless nights. If I hadn’t gotten out sooner I could’ve been severely injured or dead. The car is with the insurance company. A field investigation has been done by the insurance. They determined faulty engine and total loss if the vehicle. It is st

My 2018 sonata has been stalling out while I’m driving more so when I accelerate.I have a baby that I’m scared to drive with in the car because it does it randomly. It has been happening more & more everyday. I got new parts/starter etc. No codes on dash. Have an appointment next week with Hyundai to take a look.

Oil consumption problem 2018 Hyundai Sonata

After only 38,000 miles, the engine seized up and failed to start. Has been a the dealership where I purchased it for 2 months and has yet to be looked at

When driving the car on the highway - "check engine - hybrid system" warning lights come on and indicate hybrid system issue and to shut car off immediately. Extreme safety issue as the car goes from highway speeds to 35MPH almost instantly. This has happened seven times now and Hyundai keeps indicating that technicians are following engineering guidance in fixing the issue related to the knock sensor. The seventh occurrence happened on May 23rd of 2023. First one was in December 2021. As Hyundai is unable to correctly fix the issue I have repeatedly asked for them to replace the car since it is an extreme safety issue but they will not do so. Still waiting for diagnosis of the latest occurrence from May 23rd. Hyundai does not acknowledge that this issue is of safety concern and just indicates that the issue has been fixed each time it occurs.

The contact owns a 2018 Hyundai Sonata. The contact stated that while driving approximately 30 MPH, the vehicle lost motive power and stalled in traffic. The vehicle was misfiring, and the RPM was abnormally elevated. While driving 40 MPH, the vehicle stalled again. There were no warning lights illuminated. Additionally, the vehicle was consuming an excessive amount of engine oil. The contact was adding approximately two quarts of engine oil every two weeks. The vehicle was taken to the local dealer but was not diagnosed. The vehicle was taken to another local dealer, Twin City Hyundai (3024 Alcoa Hwy, Alcoa, TN 37701, (866) 229-3953) but was not diagnosed or repaired. The manufacturer was not yet contacted. The failure mileage was approximately 33,000.

In January, At 65k miles I took my car in for an oil change. I informed them I was putting a quart of oil every month for the last 3 months just to keep the oil light off on my dash. Tech told me all Hyundais are burning oil and to just drive it until the engine blows and I’ll get a free engine replacement through Hyundai. The following month in February, I went to get my back brakes done. Mechanic told me I had no oil left in my car. They filled it up for me. In March, I took my car back to the dealership service center and demanded service. I was told I needed to do a combustion cleaning which would cost $700 and my extended warranty would not cover it because it’s considered general maintenance. I threw a fit and they agreed to do an oil consumption test. A few days ago I hit the 1k miles I was supposed to drive and took my car in for the first check. It was almost 2 quarts low and they said the next step in Hyundais flow chart is the combustion cleaning. They told me 1. It doesn’t actually clean anything and 2. Hyundai says this is the fix to the issue but it doesn’t actually fix anything. They said after, we would do another oil consumption test and then we could submit to Hyundai under “good faith” and ask for an engine replacement. I started researching and see this is a major issue with Hyundais and leave people with a blown engine and Hyundai refuses to cover anything. I traded it in today and got a new car, not a Hyundai!

Was driving on freeway on the way back from visiting family in different state when rpms dropped off and suddenly lost power. Car began shuddering and check engine light started blinking. Put hazards on and somehow managed to pull over to shoulder. No problems with car or anything to indicate anything was wrong before this. Called to have car towed to dealership where they said there was a software problem and it was falsely indicating low oil levels. ECM was reset and software updated for $233 which they said fixed the problem. Said that carbon deposits may have caused the software to misread and that may have been why there was no indication of problems before. Hope so because i have a long drive back.
