This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The contact called on-behalf of her daughter who owns a 2015 Hyundai Sonata. The contact stated that while her daughter was driving approximately 70 MPH, the vehicle started vibrating abnormally. Additionally, the vehicle inadvertently decelerated to 35 MPH. There were no warning lights illuminated. The driver was able to safely drive the vehicle to the residence. The vehicle was taken to an independent mechanic and diagnosed with engine failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 42,000.
I have to continue to put oil in my car and get my oil change every 30 days due to oil leak. I have been to the mechanic and had my oil gasket changed, engine clean etc-?? and I-??m still buying if oil and getting oil changes. I would get oil change and as soon as it gets close to 30 days my oil light comes on.
Major oil consumption going on for years. Took in to dealer two years ago, they know there is a problem. They told me I could spend thousands of dollars to tear it apart to find out what is going on, and also told me to call corporate. I got no where with either, even though they recalled the engine in other Sonata cars, just not our ECO model. Slowly started having throttle issues at 4 to 5 year mark. Informed dealer service center that it wasn't moving like it should when gas was pressed. Now, the car is having major problems with acceleration. Barely would go in reverse, drove 1.5 blocks, speed not matching to throttle, press on gas, barely moving from a stop, going really slow, had to turn around and take back home. Our problem with the car is the same that others are complaining about. The car is not safe for a 7 year old car that started having problems at the 4 to 5 year mark.
The contact owns a 2015 Hyundai Sonata. The contact stated that while driving 40 MPH, the vehicle failed to accelerate while the check engine warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the throttle control module needed to be replaced. The vehicle was repaired however, two weeks later the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the Voice Coil Motor (VCM) needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 127,828.
1/2022. My vehicle start leaking oil. Vehicle was under warranty. Had multiple things replaced. Thought oil leak was fixed. Not even a month later in 2/2022, vehicle was leaking oil again. Brought it back to dealer & they redid gaskets, seals, etc. 4/22/22, have no even put 3000 miles on vehicle since it was at the dealership & there was a knocking noise coming from under my hood. Called the dealership and they said I needed to get it back to them. Oil consumption test was never done because it was assumed that my oil was low because it was leaking. Both times oil was put in my vehicle. On 4/28/22, I was at work and went outside to check my oil and there was little to no oil on the stick. I immediately added 5 quarts of oil which is required for my vehicle. The knocking did not stop. I left work to run a brief Errand on 4/29/22, and had just pulled out of work onto a very busy four-lane highway. All of a sudden I hear this big boom under my hood, my car locks up and my oil light comes on. I immediately took my foot off of the gas and coasted into the next driveway at a business. There was oil all over the road and pouring out from under my car. It happened to be an auto parts store. A mechanic came outside and looked and said a rod went through my engine block & oil was pouring out of my car. I started to have an anxiety attack and went into shock. Luckily I was not on the interstate because it could have been very bad. I am now without a car. None of the rental car Places have any vehicles available and I have a full-time job & single mom with 2 kids. The dealership was nice enough to have my car towed to them 45 minutes away. They Then tell me about an oil consumption problem with Hyundai and there is a big class action lawsuit. This should have never happened. Apparently the oil consumption was never sent out as a recall or anything else so I was unaware of it to even know to check my car other than regular oil changes.
My 2015 Sonata has been going through at least a quart to a quart and a half of oil every thousand miles. I researched this and found out that the 2015 sonatas have a very common problem where the engine needs to be replaced. There was huge class action suit against Hyundai and I'm worried that this is going to lead to bigger problems for me. I have gone to the dealer for 5 times and they keep telling me I'm not burning enough oil to justify the engine replacement but I'm not comfortable with their report.
There's an oil line to the turbocharger; my guess is to cool the turbo and it came off spraying oil all over the engine compartment and when it hits the turbo the heat from the turbo would create smoke that would get into the passenger compartment and billowing out from under the hood. Hyundai had a recall campaign to fix this issue for the same 2.0T engine but only for Sonata models from 2011-2014 and they deny that this recall applies to my car because it's MY2015. Same car, same engine, same turbo oil feed line and they refuse to honor repair costs for recall campaign 16-01-071. I had to go through this risky incident and then have to pay $720 in repairs that was caused by a design flaw.
Was pulling out of a parking lot and the engine stalled. Would not crank over again. Mechanic took the timing cover off to inspect and found timing chains are all in working order. Will all engine belt driven accessories disconnect and timing cover off. Engine cannot be rotated with a breaker bar. Technician says the bearings are seized.
While driving in city traffic, 45 mph zone, my car suddenly lost power, engine RPMs dropped, engine off, power steering impaired, I had to drift into turnout and assess. Car restarted, and I could drive, but RPMs would not exceed 1700, car wouldn't shift gears, speed would not exceed about 15 mph. No engine warning lights, no oil pressure indicator, no excess heat. I found I could drive at low rpms and manually shift gears to increase speed. I got the car to the local Hyundai dealer (Taylor hyundai, Augusta GA) and it has been there 8 weeks. They are telling me the engine has failed because I failed to change the oil for 14 months. They said my oil pan was empty. They asked me for maintenance records and said they were inadequate, and the engine needs to be replaced, may cost $6000 or more, warranty invalid. The car has 56,000 miles. Safety was put at risk due to sudden loss of power in busy traffic. Driving the disabled vehicle was risky to surrounding traffic, as the car could not maneuver quickly. I have read about similar failures with Hyundai Sonata vehicles, and a class action suit settled for 2011 to 2014 model vehicles. My car is still in the shop, unrepaired. I had to buy another used car in the meantime.
We have had some issues but take very good care of the car maintenance wise. The car went into limp mode and we took it in they ran it and came up as the knock sensor.. I noticed there was a huge recall for these cars. What can I do" It has 140000 miles and again we keep up on the car. Is this something I need to seek counsel for" Thank you for your time. I look forward to hearing from you, Dominique
The contact owned a 2015 Hyundai Sonata. The contact stated that while driving at approximately 60 mph, the vehicle decelerated independently while the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the sparks plug and the PCV valve needed to be replaced. The vehicle was repaired however, the vehicle check engine light recurred. The vehicle was taken to the dealer where it was diagnosed but the failure was undetermined. The vehicle was taken to another dealer St. Charles Hyundai where it was diagnosed but the check engine light continuously illuminated. In addition, the contact mentioned while driving, there was a pop noise and noticed white smoke was coming from underneath the vehicle. The contact pulled over to the side and exit the vehicle. The fire department extinguished the fire. A police report was filed. The vehicle was towed to the tow lot and was destroyed. The dealer was not contacted. The manufacturer was not notified of the failure. The approximate failure mileage was 143,000.
This vehicle is consuming large amounts of oil. Up to 3 quarts and 1,000 miles causing the oil light to come on. Hyundai did an oil consumption test with failing results. Due to this they did a deep combustion chamber cleaning. The car still continues to burn excessive amounts of oil. I am told that this does not qualify for the class action lawsuit because it is piston related and not rod bearing related. There is a burning smell coming from the vehicle that does not smell like burning oil. I am highly concerned that the vehicle is going to catch on fire yet Hyundai refuses to do anything about it.
While sitting at a stop light the vehicle suddenly would not accelerate and would not rev the engine above approximately 2000 rpm. Then the check engine light began to flash. I was nearly rear ended because the vehicle just would not accelerate.
The contact owns a 2015 Hyundai Sonata. The contact stated while driving at 45 MPH and approaching a stop sign, the vehicle started shuddering and stalled. The contact noticed smoke coming out of the hood of the vehicle. There were several unknown warning lights illuminated. The contact was unable to restart the vehicle after several attempts. The contact was able to push the vehicle to the side of the road with the assistance of a bystander. The vehicle was towed to an independent mechanic who informed the contact to take the vehicle to the dealer for repair. The vehicle was then towed to the dealer where it was diagnosed that the engine had failed and needed to be replaced. The dealer sent a claim with diagnostic report to the manufacturer ; however, the manufacturer declined to cover the repair. The contact followed up with the manufacturer and was informed that they could not assist as she failed to complete an unknown software update, under Service Campaign Number: 553, designed to report vehicle imbalances prior to the engine failure. The vehicle was not repaired. The failure mileage was approximately 142,000.
The contact owns a 2015 Hyundai Sonata. The contact stated that while either at a complete stop or while driving under 25 MPH, the vehicle would shake with the check engine warning light illuminated. The contact also stated that the vehicle would intermittently lose motive power while driving at highway speeds. The contact stated that the battery and oil warning lights would be illuminated. The contact took the vehicle to an independent mechanic where the mechanic discovered a misfire in cylinder # 4, as well as damage to the cylinder head. The vehicle was diagnosed with engine failure. Neither the dealer nor the manufacturer had been notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 105,000.
My engine is seized. Driving down the road normal all the sudden driving 14mph peddle all the way down to the floor. Mph slowly decreasing until it get to a complete stop and dies. The car turns on but does not crank. Check engine light is now on battery light, oil light and key fob light without warning. Did not have knocking, shaking or stalling of the vehicle. Vehicle was diagnosed and towed twice.
This is a follow-up to former Complaint #11450586 (05-Feb-2022) and confirms that both my local Hyundai Dealer -and- Hyundai Corporation (USA) are aware of this diagnosable- and fixable problem-?"but they fail to issue a recall. In fact, a Service Advisor at my dealer expressly vocalized that 1) he himself [excluding his colleagues] has seen at least -2- of the same incident recently; and that 2) Hyundai Corporation (USA) issued a -??(service) bulletin-?? about the problem. PROBLEM: The vehicle: 1) has a high idle; 2) shows a solid-illuminated CEL/emissions light; 3) severely resists braking-?"my vehicle would even slide through stop signs; 4) fails to -??pick up-?? normally; and 5) drives unsteadily. This is at minimum and is my experience from both last week and from the original report on 05-Feb-2022. As explained to me today (28-Mar-2022) by my Service Advisor, there is a known fault with a component within the engine (Powertrain). Specifically, there is a tube that is-?"as I understand-?"meant to be FREE of fluids. However, and per the Bulletin, the tube becomes full or over-filled with oil from the engine (Powertrain). Further, the Advisor suspects that changes in temperatures (e.g., such as the teens back in Feb 2022) causes that oil/fluid to expand and contract, causing (further) damage. This issue must be remedied by Hyundai Corporation (USA) immediately because it is a *SAFETY RISK.* My Dealership emphasized severely how unsafe it would be to drive the vehicle off their premises without a repair. I-??m fortunate because I-??m the original owner and thus am covered by the 10 yr/100,000 mi Powertrain warranty. PLEASE SAVE LIVES FROM THESE -??FLYING-??, UNCONTROLLABLE CARS BY MANDATING A RECALL. * will provide Dealer-??s documentation once vehicle is repaired. I was advised to wait 2-8 wks for parts and repair.**
My car has been stalling, hesitating and sometimes I feel the engine shake when using the gas. I brought my car to the dealer to have the most recent recall fixed and asked them to diagnosed what else was going on with my car. They told me the stalling was just due to the recall. However, the very next day my car was acting up again. Additionally, the car at times will accelerate when I am not pressing on the gas. I don't think I need to go into detail about how my safety and the safety of others is compromised when you have a car that accelerates on its own. Lastly, there is no check engine light on. This has been ongoing for several weeks.
