The engine burns oil, I have to get spark plugs every two months, and put oil in it almost every week. The check engine light is now flashing and is throwing more sensors. The paint on this car is also all peeling off.

I was going 80 mph on the interstate and suddenly my car went into limp mode and shooked really hard and dropped to 60 mph. I had to swerve to go onto the side of the road. The car behind me almost rammed into me. I contacted hampton hyundai for days to schedule an appt. I finally was able to drop off my vehicle to them but now they are telling me they have to do an oil consumption test but my car is in limp mode and it shakes when I drive it. The car is dangerous and they are trying to charge me $500 for a fuel pump replacement ( which I have a warranty of but they notified me that does not count but it matches exactly the possible reason). As you can see in the documents, they did not note that my fuel pump was broken. They just asked if I wanted to pay it so they can get started. I get normal oil changes done. They haven't even done a rod bearing test but just looked at the knock sensor and was telling me that they wanted to charge me to get that changed.

Car does not when temperature drops below 30 degrees (Fahrenheit) even when garaged so you cannot drive car and u have to be towed several times at night. Local dealer stated unaware of issues but there is forum of Hyundai owners who have this problem with 2018 sonata. A local mechanic studied issue and did replacement on the relay switch and starter and now car starts in cold weather. It took me four years is stress and I put in complaint to Hyundai and they did nothing to compensate me for parts. This is a very big issue to be somewhere called late at night and not have reliable transportation.

- Component or system that failed: engine (cylinder #4 misfire) - Safety was put at risk twice: once when knock sensor went off on interstate (October) and engine went into limp mode (aka protection mode). Required a tow from the, which was tricky with a vehicle full of passengers. Safety was put at risk gain when vehicle began to stutter/sputter on interstate (December). Drove 4-cylinder vehicle essentially on three cylinders an hour to dealership - Problem has been confirmed by dealer (Southern States Hyundai, Raleigh, NC) - vehicle has been inspected by warranty inspector, who requests approval before disassembling engine to diagnose issue. However, based upon maintenance records and manufacturer's history of engine issues (more on this below), owner should not be liable for investigating a well known issue. At the time of this writing, the issue has been escalated beyond the dealership and warranty to Hyundai Motor America, and currently awaiting the results of their findings. - symptoms of the problem include constant oil leak from vehicle purchase in May 2024 up to engine failure in December 2024. Various temporary remedies (oil changes and repairs, including oil drain plug gasket replacement, crush washer replacement, and replacement of cracked oil pan) did not fix the issue. Additionally, in the October incident, Hyundai dealership (Sport Durst Hyundai, Durham, NC) simply updated the knock sensor detection (KDS) software, despite the vehicle previously receiving the update in 2019 (this can be verified). Finally, owner, noted "engine knocking" (aka 'tapping') in vehicle prior to engine failure. - Hyundai (the manufacturer) settled a class action lawsuit in 2021. Vehicle is one of the vehicles listed under Class Vehicles, but dealer, nor warranty company, nor Hyundai seem to want to resolve issue, which both alienates owner and presents a safety hazard, as the vehicle is unsafe to drive. All claims here will be supposed via documentation and images.

My cars engine is failing. My safety as well as other around me are at risk because the more oil my engine consumes, the more it is likely to quite literally blow up. My car just hit 60,000 and my dealership has informed me that I need an engine replacement. The manufacturer will not take accountability for their fault engines, even though my dealership told me they see this same engine problem come in every single day. Since before my car hit 60,000 in October 2023, my oil light came on which is odd because I-??ve always maintained my car well. Since then, my car has been burning 4-5 quarts of oil in 1000 miles. My engine has an oil consumption issue, as do many other Hyundai models but Hyundai refuses to acknowledge this issue. Go on Tik tok, look at how many people are having the same problem. Call a Hyundai service center, any one of your choice, they will tell you that they see oil consumption motor issues every day. Hyundai corporate told me it is not their problem, and good luck. This is unethical and immoral and there needs to be a recall. There is no reason why I need an engine replacement at 60,000 miles.

43000 miles on car. original owner. new battery. car does not cold start in the morning. all electronics light up, but engine doesn't start. This is a known issue from all the posts i found online, yet Hyundai has not issued a recall. I paid 300 for a battery 2 weeks ago and the issue didn't resolve. Now i am being told by dealer it is the starter and it's not covered because my 5 yr warranty is expired (my car is 6 years old). This is a known safety issue across the 2018 Sonata line. This should be a recall or bulletin, instead I have to come up with hundreds of dollars more to replace a starter on a car with ONLY 43,000 miles.

Approximately 6-8 weeks ago, I was driving home and my oil light began turning on and off. This had never happened before. It was nighttime and I was only a few miles from home so I continued driving. The next morning, I checked the oil to find that the reservoir was bone dry. There had been no warning light whatsoever prior to this incident. At this point, the vehicle had about 65,000 miles on it. I had to put 2 quarts of oil in before it would even register on the dipstick so I could get it to my mechanic. Upon arriving to his business, he explained that Hyundai is well aware of this ongoing issue of oil consumption but they are doing nothing about it. I had not driven excessive miles without an oil change and faithfully get it changed between 3,000-5,000 miles, which is perfectly acceptable for this vehicle. I have all receipts from these changes. I have begun to maintain a record indicating the oil that I have added over the last 1,700 miles. It has been 2.5 quarts. The morning I brought the car to my mechanic I reached out to the Hyundai dealership and was told I would need to pay for a diagnostic, then two oil consumption tests. I declined and promptly reached out to Hyundai corporate. They told me the same nonsense and then offered to have their consumer division reach out to me. Ultimately, that person told me I would need to do the same thing, so they were entirely useless in facilitating any reasonable resolution. I subsequently found out about the oil consumption problem that thousands of people have reported in various models and years. I joined a few Hyundai oil consumption groups on Facebook and now realize how many people have been impacted by this issue. I still owe $5,600 on the car but feel that the issue will not be handled by Hyundai and don't wish to have ongoing concerns with driving the car and constantly topping it off with oil. As a result, I feel that I am forced to pay off this car and buy something else.

My car is part of a campaign due to rod-bearing failure where the engine experiences problems such as complete failure, vibrating, hesitating, engine light on, and oil light on. I've been communicating with Hyundai who is not helping me with this issue. I was advised by them to continue driving the car "until the engine seizes", or I hear "a loud knocking noise". Upon inspection, three local Hyundai employees "agreed 100%" I need a new engine. However, per these employees Hyundai Corporate will not approve the replacement even though the vehicle is constantly experiencing the above symptoms above, simply because there is not a "loud knocking noise" coming from the engine. Even though ALL the other issues are present. This is very unsafe. I have a minor child I take to school daily, for an advisor to advise to drive the vehicle until "the engine seizes" is extremely dangerous, especially when they are aware my VIN is associated with engine replacement. My car exhibits symptoms of a rod-bearing failure and this multi-billion dollar company is taking advantage of hard-working urban mothers, by turning a blind eye and trying to require me to pay thousands of dollars up front for a problem THEY created by selling a vehicle with faulty engine. Again, the technicians indicated i in fact do need the engine replaced, but that Hyundai Corporate will require me to pay for a diagnostic test, rod-bearing test, and engine compression test because Corporate does not take their word for it. The fact a auto manufacturer is advising people to drive in such an unsafe manner is disheartening. If my child and I get injured in an accident by following their advice, our blood will be on their hands!

The electrical and engines in these cars are horrible. The steering wheel keeps locking up while driving cause everything to flick inside the car. This is a major safety issue for me when I am driving and I am unable to control the steering wheel. Dealership claimed they don-??t see the issue with the car which I am stating. The vehicle was only inspected by a mechanic and since Hyundai said they couldn-??t find anything a 3rd party confirmed that this was a ongoing issue and dealership could-??ve caught it but it-??s cheaper the sell the car. No everything happens at once especially if I-??m turning or driving under 40 mph. First appeared 15 days after I bought the vehicle I alerted the dealership immediately

- Moore, SC, USA

The vehicle is burning oil at a high rate in a short period of time, a known issue that is affecting thousands of other people, and Hyundai refuses to issue a recall to fix this issue. If I forget to add oil every 500-1000 miles, I risk the engine locking up while driving. Their cars are dangerous to drive and are unsafe to be on the road with other drivers. They put profit over the safety of their customers.

While driving on the freeway the car would not accelerate over 45 mph and then began to lose acceleration all together. The oil and engine lights came on and we were able to pull to the shoulder. Turned the engine off and then was unable to restart. Losing power on the freeway would be considered a safety risk. The car was towed to the mechanic who checked the oil and found it was three quarts low, however, two months prior the oil had been changed along with the oilpan being replaced as it was cracked. It was then towed to the dealership and after three months of diagnostics and inspections I was told the engine needed to be replaced. The Hyundai dealership is unwilling to share any communications between them and Hyundai USA. In 2019 the ECM was updated per recall 953. The car is available for inspection at your convenience. I think it's important to note that this is a six-year-old vehicle with under 55,000 miles.

As detailed in the attached letter to Hyundai, the car has had multiple engine issues that the company refuses to resolve even though they are well aware of the on-going engine problems in Sonatas. The problem started in August 2023 and is on-going.
