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

ENGINE
I have observed that my Hyundai sonata 2017 randomly lose power while driving. Also, sometimes the car vibrates when I am driving. I went to the mechanics few times for them to check it, and they requested to change the spark plugs as well as the coils, which I did but it continuously do that. I usually go to the Hyundai car dealership for oil change, and they will tell me whatever I need to change in the car, which I always do but still it does that. I believe this is not safe especially when you are driving over 50 miles an hour on a high way, and the car randomly loses power; this can cause a serious accident. I am requesting the intervention of your office in making sure that car company’s uphold to the safety of everyone plying the road.

SERVICE BRAKES
Around mid-April of 2023, I was driving and i attempted to LIGHTLY apply my brakes and an alarm starts going off. Then the brakes VIOLENTLY start grinding. I went from 50mph to an immediate 10mph. The dealership said they replaced the fuse that SHOULD solve the problem. It did not. My car has been sitting at the dealership for a whole year now. They have not been able to update me on when it will be fixed. They have made ZERO attempts to provide me with a reasonable accommodation for my ONLY form of transportation being their lawn ornament for a year. I lost my job. I lost my place to live. And they are doing nothing. Now they say they're going to be replacing fuses to fix the issue but they already tried that and it did nothing. Every time I call to ask about an update, they put me on hold for over 10 minutes and then say there's nothing they can do at this time. The only thing they have tried to do is attempt to get me to buy a whole new car, which is out of the question because mine is completely paid off. This has seriously affected mine and my child's life. I don't even have a vehicle to go grocery shopping or make it to dr appointments or shoot functions because I have no way to get there.

SERVICE BRAKES, ELECTRICAL SYSTEM
•brake failure •this has happened at indiscriminate times including the highway, suddenly the car tells me to stop driving and the brakes don’t work as they should, no telling this would happen until it occurs. When pressing brakes, a loud noise rumbles through the car and I am no longer able to drive at any speed higher than 5 mph (an issue for being on the road) risk of possible collision as this happens suddenly and gives short time to take action •UKNOWN •was inspected by local dealer, they said it was the primary pressure sensor which is a part of the Hydraulic brake booster pump. They wanted to replace the entire hydraulic unit even though it was only the sensor that was faulty and it would cost me $3,503.61 which is an ABSURD price for an electrical issue that I did not see coming at all and it is a robbery of regular people who need their cars to get to the places they need to be (work and family) this is NOT a luxury, I need my car •no warning signs or lights until the issue actually occurred. The only light that showed was the ABS lights, maybe it’s linked to the recall about the brake fluid leaking causing fires?

ENGINE, FUEL/PROPULSION SYSTEM, WHEELS
Approx one year post engine replacement, and 2 weeks prior turbo system replacement, I am having major issues with my sonatait struggles to stay started, it always hesitates and doesn't want to move when I press accelerator, shakes jolts and shudders, the smell of burning oil comes thru the vents and even smoke comes out from under the vehicle. The engine is leaking masses amounts of oil that seem to be leaking from all over the under carriage and half way to the back underneath the car, oil is in the wheel wells, and even splashed on the rims, the spark plugs are covered in oil, huge plums of white and dark smoke come out of the tailpipes, literally blinding anyone behind me, press the accelerator to the floor and it just shudders and smokes even more, check engine light is on and states malfunctioning turbo system, boost pressure sensor malfunction, sluggish will not gain speed, oil within the turbo blow by hose and in intake hose area, now I have coolant pouring out and the reservoir the coolant will be literally boiling. This is not good at all especially after a year post engine replacement and turbo replacement. When the car is started I push start and car struggles to start the starter keeps screeching and car shudders for a good 45 seconds before it either dies out or finally starts. This vehicle should be a lemon and bought back regardless of age condition etc. A vehicle after engine replacement of only one year should not be pouring oil out of the engine, failed head gaskets,misfiring and leaking coolant. I keep receiving recall notice after recall notice in the mail stating I have recalls that need to be addressed but when checking using my vin it says there are no recalls needing fixing, that makes me uneasy and I don't feel safe driving the vehicle I lost faith in it all together

ENGINE
Hyundai Theta II engine has known defects with excessive engine oil consumption. Numerous consumers have complained of this issue as it appears widespread to the entire line of Theta II engines. A recent class action has limited the scope of the recall but an easy search can see it impacts (or has the potential to impact) nearly all Theta II (six gen) engines from Hyundai. The issue is that the scope of the recall needs to be widened to cover others who are impacted who currently have no recourse. Many are facing the same situation, which can easily be found with a brief search online. [XXX] At this time the issue is the car stalling at unknown times, fire from oil being displaced in other areas and various other issues due to improper and unusual oil consumption. The best situation would be to force Hyundai to review and expand the scope of their recall immediately. I found that I had excessive oil consumption which was causing my car to grind and shift heavily sometimes jerking on the highway. While I didn't crash, that possibility did exist when my car continually grinded heavy between shifting. I took my car to the dealer where they confirmed this issue. However, Hyundai declined to remediate. There are no warning lights and this could easily result in a crash, or fire. Hyundai has records of my maintenance, as my car is only serviced by the dealership where the car was purchased and I am the original owner.

ENGINE
My car began consuming alarming amounts of oil as well as emitting a knocking sound and hesitating while been driven. I went to Patriot in Boyertown, PA and they advised me to contact Hyundai as my engine was failing, could cease at any minute and exhibited all of the signs associated with their engine recall/rotor warranty extension. I have had two diagnostics done to the car that found metal as well as three other major signs associated with their engine recall and warranty extension. Hyundai has now asked me to pay $529 out of pocket for additional diagnostics they are requesting as part of their recall and warranty despite the fact that I have already had diagnostics done telling me what is wrong with my engine and additional diagnostics provides no benefit to me. When researching the issue, it is alarming the thousands of other accounts detailing the lack of honoring the recall and warranty as well as practices that sound illegal when it comes to safety and consumers. I would welcome an inspection of my vehicle as I believe them to be trying to not honor their own recall and warranty and replace my faulty engine that they sold me.

ELECTRICAL SYSTEM, POWER TRAIN
While driving the 2017 Hyundai Sonata Plug-In Hybrid, the car will begin to stall, a rapid number of audible beeps will start, the "Check Hybrid System" notification will pop up on the dashboard, and the "Check Engine Light" appears.. The car therefore cannot be driven anymore, and I am forced to pull over to the side. In order to fix the issue temporarily, I need to turn the car off and turn it back on again. Once this is completed, both the "Check Hybrid System" and the "Check Engine Light" disappears and the car can be driven again. An OBD Scanner is unable to find exactly what is going on as the "Check Hybrid System" and the "Check Engine Light" no longer appear. This has happened 4 times now within the span of 3 months. The people at risk are me (the driver), my passengers, and potentially everyone else on the road in my nearby vicinity as the problem occurs. This problem has been confirmed by the dealer in their Hybrid vehicles. This vehicle has not been inspected yet but that is an ongoing process.

ENGINE
I was driving on the highway yesterday at 85mph when the engine light started flashing and the rpms went haywire. Then within 2 minutes of this taking place the car began to slow down and not want to go any further. I managed to get over to the shoulder of the road when the engine just shut off and would not restart. The engine drinks oil like crazy. We put oil in it every week and get frequent oil changes. On the day that it broke down on, I had been to the oil lube center that we do business with and had them top off all of my fluids. After looking into this problem online, it appears that there are many other people suffering with the same lemon of a car. Hyundai knows that there is a real problem with the 2016 Sonata, and they are not doing anything about it. We have spoken to the dealerships, and they say there's nothing they can do about the problem because it is out of warranty. We're still making payments on this vehicle and can't even drive it now. The mechanics said that the vehicle needs a new engine. Hyundai needs to issue a recall and help their customers instead of turning a blind eye to the problem. Driving at high speeds with absolutely no indication that there is a problem is a real danger. No indication lights had come on other that the flashing engine light and then within two minutes, dead on the side of the road.

ENGINE
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
