Exterior lighting, turn signalSep 24, 2021
Hyundai Motor America (Hyundai) is recalling certain 2015-2017 Sonata, 2016-2017 Sonata Hybrid, and Sonata Plug-In Hybrid vehicles. The Smart Junction Box (SJB) software logic may not properly interpret the signals received from the multifunction switch, which could cause the turn signal to activate in the opposite direction of what the driver intended.
A turn signal that activates in the opposite direction of what was intended by the driver increases the risk of a crash.
Dealers will update the SJB software, free of charge. Owner notification letters were mailed November 19, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 210.

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.

My Sonata is burning excessive oil since January 2022 have to add a quart a week but there is no oil leak.
Engine, Apr 29, 2022
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.
Engine, Apr 26, 2022
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

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.

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 *F 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. **I 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.

Car has been consuming an excessive amount of oil (1-2 quarts per week). While driving down the highway the oil pressure light came on and the engine started clicking and knocking. The engine died and all the dash lights came on. The car was coasted to the side of the road and towed into a local mechanic. The engine had seized and presumably dumped all the oil at the time of the engine failure since the engine had no oil when diagnostic was run. Car was taken to Hyundai dealership and is awaiting diagnostic and repair.

While going home on highway 95 at approximately 70 mph. The vehicle stalled almost causing many accidents. Thank goodness I steered it on the shoulder and it will not restart I had to call for a Tow. This was the 3rd time this happened. The first time was approximately a month in 2015 after my purchase it stalled on the highway. Again, in 2017 it once again stalled on the highway while I was driving. The dealership has told me on all 2 previous occasions that they had fixed the problem and it wasn't going to happen again. Here we are in 2022 and it stalled again. Why can't they just replace the engine? This is the second week and my car is still in the dealership which they are saying they don't know what the problem is smh.
