My 2016 Hyundai Sonata has an oil consumption problem it is using 1 qt of oil for every 532 miles which is causing it to lose power and stall out. The first time it happened I was driving on the highway through a tunnel which put myself in danger of being struck by other vehicles traveling at high speeds I had my car towed to the dealership where they told me it was because my starter had a dead spot in it and then on further investigation they said my car had no oil in it even though I had had my oil changed recently and per manufacturer specs I am supposed to go 5000 miles between oil changes I had to get my timing chain replaced which cost me $3000 dollars and start an oil consumption test after I completed that I was told to have combustion cleaning done because that would fix the problem and then entered into another oil consumption test and my car is still using 1 qt of oil every 532 miles it still loses power while driving and acts like it wants to stall out the dealership advised me I need a full engine replacement and Hyundai has denied the claim twice I’m concerned for my safety while driving because of the issues with the engine

The engine is burning about 3 quarts of oil every 500 miles of driving. It is causing carbon to gunk up the spark plugs every month and a misfire will happen at random. I tried contacting the dealer and even though they have several complaints, they said they won’t do anything. I have brought it to several mechanics and they say the manufactured engine needs to be replaced.

POWER TRAIN, ENGINE
I purchased a 2016 Hyundai Sonata 2.4L with the Theta II engine back in December 2016. I purchased it as a Hyundai Certified Pre-owned (CPO) vehicle, with the 10 year, 100,000 mi powertrain warranty. The car had approximately 36,000 mi on the odometer. Starting at about 60,000 mi on the odometer, I began to notice excessive engine oil consumption. The factory has made attempts to remedy the issue under the 10 year, 100,000 powertrain warranty coverage, but none have lasted more than 1,000 mi. After 1,000 mi of a "repair" service, the engine is back to consuming lots of engine oil. As a result, I have resorted to checking the dip every time I fuel up, and top off engine oil as it gets consumed. To my estimate, my oil consumption is between 200 to 300 mi per qt of oil consumed, which is well in excess of the factory acceptable levels of 400-500 mi per qt of oil consumed. Then, Hyundai USA's Customer Care's customer reps, case managers, and Hyundai National Managers all have told me in several occasions over the past two years that my car is either "out of warranty" (despite not yet having reached the 10 year, 100,000 mi mark, nor the extended 120,000 mi mark) or that Hyundai has never sold any Hyundai CPO cars with the 10 year, 100,000 mi powertrain warranty in the US, despite my sales records and owner's records indicating that my car came with the warranty. Hyundai is trying to breach its 10/100 powertrain warranty contract and trying to have me pay for the diagnostic and repair costs out of my pocket.

On 04/25/2023 while driving to work my car all of a sudden started flashing “check engine light”. The flashing was continuous and my car lost almost all power and would not go above 2 rpm. It was terrifying. I immediately notified Hyundai and had my car towed to dealership. Now Hyundai is telling me I can’t get rental reimbursement until they approve and engine replacement, which can take up 2 months.

FUEL/PROPULSION SYSTEM
I have owned my car about a year. There were no problems from the beginning but just a few days ago I was waiting in my car and turned the heater on. The strong smell of fuel came through the vents I immediately shut off the vents and took the car home and did not drive it for a few days. After a inspection from myself to see if I could find the issue nothing was found and so I took the car into a shop to have them inspect it. They quickly found that the metal high pressure fuel line was leaking at the connection to the fuel pump. They said I was lucky that the car had not caught on fire during the drive to the shop as the leak was right near the spark plugs and the fuel vapors were very strong. They tried to reestablish the seal and the leak is worse now. The car is undrivable and I will have to replace either the fuel line and/or the fuel pump.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
I have had replaced my taillight bulbs 8 times in the last year. They keep blowing out and getting so hot they melt the taillight assembly. I replaced the whole assembly a couple months ago and it is already melted so bad the light bulb will not fit properly or stay in place. This is a fire hazard and also a safety hazard as my taillights quit working at anytime.

ENGINE, UNKNOWN OR OTHER
Occurrence: This has been a recurring issue for over a year (over a year, might be closer to two years now) for our PHEV Sonata. It has happened approximately 10 times. Problem: Total engine shutdown when driving the car. "Shut down engine" type error message pops up and cannot accelerate. Steering still works, but it can be hard to pull over due to lack of engine power. The car can be restarted after shutting down, but must first come to a complete stop and into Park. Safety Issue: The car stops working. Obviously, this would be quite dangerous on a busy road, a highway, or if you were taking a left turn, etc. Confirmation: The dealer indicates that the hybrid battery is a problem and should be replaced. However, due to supply chain issues, we have been waiting for over a year for the replacement. **** Reproduction Steps: **** We have found that it is most likely to happen with a fully charged battery and a sudden braking action. I suspect the issue happens when trying to charge the battery but due to its condition, it shuts down instead. It tends to happen: 1) Full Charge: Battery is fully charged overnight or "topped up" to full charge 2) Sudden Braking: Having to brake hard, such as being cut off. We have found that adjusting charging and driving habits has reduced but not eliminated the issue. Suggestion: I would suspect that having some electrical component to prevent a sudden overcharge might eliminate this problem (shunting excess current or turning off regenerative braking for sudden stops). Warning Messages: A warning message is seen, but it happens at the same time the engine is shut down and disappears before you could take a picture of it (as you are busy trying to do an emergency pull over).

I was driving along and stopped at a double red light. As the light turned green and as I was driving through the first green light, all my dash lights came on my car lost power like it stalled out as I was going through second green light, I was able to turn into gas station and it came to a complete stop. So I put it in park and pushed the brake and button as I normally would to start my car and it wouldn’t do anything?! I had to have it towed and the driver informed me that there has been an engine recall and I never heard of this for my 2013 Hyundai Sonata!! I’m glad I wasn’t going faster and had a place to pull my car into and myself and my son weren’t hit by another vehicle causing us physical harm! I’ve tried several dealerships service centers and have yet to have a call back from any of them!! I’m extremely upset that the engine would shut down like that while I was going at least 35 miles per hour cause I had just got off the highway doing 70 mph! Why would an engine do this with no warning or issue prior to this?

Known connecting Rod recall since 2020. Hyundai manufacturer just installed a knock sensor and erase code or recall on system. Car having acceleration issues since and been going back to the dealership and states they can’t find any issues since the car is running and has no warning light. I demanded the connecting Rod to be repaired but dealership refused to do so. So where do we go with this recall?

My car would not exhilarate properly. When came to a stop it would spit and sputter to even move. Could not get up to 60 mph and no less than 20 without it wanting to sound like it was going to die. Took it into a dealership to have it looked at and was told their's several recalls on my make and model and the year of my car that I need to see if there's any on mine, then I drove it home. Now my engine won't even start after it made a loud noise. I use my car for work cause it's my only transportation.
