The engine violently vibrates and no matter how much I get an oil change it burns so fast and I have to keep adding. It's not leaking, just burning. I plugged in a diagnostic tester and it said that the 3rd cylinder was misfiring. I haven't had the car for very long, and this is not normal. I take good care of it.

My vehicle had the following symptoms: 1. Alternating between sluggish acceleration/handling AND rough acceleration with the vehicle lurching forward at times 2. Check engine light with error code P00010 3. Occurred frequently over a one month period (5+ times) This was unsafe as the car could not properly accelerate and would lurch forward at intersections. This could easily have led to a crash. We limited driving. This issue was observed at the dealer where I repaired issue. The issue is exactly the same as the issue described in the recall for Hyundai Sonata 2015 under SB-10058136-4434 and was resolved by replacement of the E-CVVT seal as described. This issue is ridiculous for me to deal with and put my family as risk given it a KNOWN issue for Hyundai in their other vehicles.

ENGINE, FUEL/PROPULSION SYSTEM
I was driving a 2016 Hyundai Sonata on a mountain highway and it started to run rough and lose power dramatically when accelerating. A dangerous situation on a steep curvy highway that has many one lane sections. Shortly thereafter a dash light came on. There was no warnings or dash lights or symptoms prior to this incident. I took the vehicle to a mechanic and ran the code. It said there was a misfire in cylinder 3. Replaced the ignition coil and spark plug for cylinder 3 and it did not fix the problem. The mechanic then pulled the motor to check the valves. Valve 3 was burnt, had a hole and stuck open. The car had approximately 75,180 miles. Well within the warranty time frame of 10yrs or 100,000 miles for an original purchaser. The mechanic had the valve machined, and replaced the head gasket and reassembled the the motor. I picked the car up and drove it home. Within 3 days I noticed an oil leak under neath the car where the engine bay is. I took the car back to the mechanic and he diagnosed a hairline crack in the oil pan. After some research I came across a letter from NHTSA on a defect investigation of Hyundai/Kia oil drain pan assemblies. This is exactly what happened to my car! I have paid 3500.00 to fix a car that has less than 76,000 miles. Hyundai needs to do better.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
While driving, the vehicle's engine light will randomly turn on and when it does, the car will lose power; meaning, when this occurs, and I press the accelerator pedal, it does not put out the normal, expected amount of acceleration. This problem will persist until I pull over, turn off the vehicle, and turn it back on. However, this does not always fix the issue. Sometimes, when I turn the car off and turn it back on, the check engine light will still be on and I will still encounter the issue. When I brought my vehicle into my local Hyundai dealership, they had the car for 3 days, and when I called to ask what was wrong with it or what they did to fix it, they told me they could not recreate the problem and therefore, did not do anything to the vehicle. So now, I'm at an impasse where this problem is not able to be recreated, thus, unable to get it fixed, but I don't feel completely safe to drive long distances. I also own a 2013 Hyundai Sonata that experienced the same type of issue, and that engine was recalled.

Been fighting with Hyundai for quite sometime to have engine repaired due to excessive oil consumption and other issues no matter what you take it they state it’s normal for you to apparently run out of oil before oil change is due. These engine are pure junk and they go out with any warning whatsoever forcing customers to foot the bill for a new engine. They absolutely do not care. I highly recommend any does not purchase Hyundai or Kia. Now that my engine finally went out they expect me to pay over 9000 for a new one when I repeatedly told them my concerns ahead of time trying to avoid this.

Hyundai Motor America (HMA) denied my engine replacement claim (PA# [XXX]) under their extended warranty program, specifically campaign TXXI. This claim involves my 2016 Hyundai Sonata SE 2.4 , VIN # [XXX] , which exhibits all the symptoms and engine damage outlined in the campaign, yet my request for a free engine replacement has been unjustly denied. Campaign TXXI, as explained in the Technical Service Bulletin issued by Hyundai, extends the engine warranty applicable to 2015-2019 model year Sonata (LF) vehicles equipped with Theta II 2.0L Turbo and 2.4L GDI engines. This warranty covers engine long block repair or replacement due to engine damage or malfunction from connecting rod bearing wear and extends to a Limited Lifetime Warranty, valid for both original and subsequent owners. o On or about [XXX], my vehicle exhibited a blinking check engine light on the dash, entered into limp mode, and a knocking noise was coming from the engine. o As I was driving the vehicle to the Hyundai of North Miami Service Center on [XXX] (21400 NW 2nd av., Miami, FL 33169) for inspection, the engine locked up and stop, necessitating a call to a towing truck company to complete the trip. o Upon inspection, the service center identified significant engine damage, including, engine mechanical failure unable to turn on, and recommended that the vehicle require a new engine replacement. o These findings align with the engine damage described under campaign TXXI. o Despite meeting the campaign criteria, HMA denied my claim (PA#XXX) for an engine replacement on 11/22/2024. o HMA based its denial to my claim on the review of engine pictures and my inability to provide evidence supporting oil maintenance intervals between 35k- 68k miles, 78k-99k miles, and 142k-163k miles. HMA cited these maintenance gaps as the basis for suspecting engine neglect, some indications of sludge found on the engine, as the reason for the engine failure and subsequent locking.

Vehicle has been repaired due to broken valve. Vehicle was unsafe to drive. Valve burnt at 70 mph. Car threw misfire code P0303 and started shaking. This issue could have caused an accident. Valves were replaced at Young Hyundai in Ogden Utah. Valves were not covered under the lifetime rod bearing recall. Several people have had this failure on the Engjne issue group page. I have a photo of the valve. It is missing a chunk of the valve head. That piece was not located during the valve rebuild. The vehicle had 116,000 miles at time of failure and is consuming 1 quart of oil every 500 miles.

Wind deflector came loose on highway after recall was performed. The wind deflector was originally reattached in 1996 shortly after purchase. The recall doesn't take into account that the manufacturing issue may of been previously repaired. I believe when the "recall" was performed(2020) the lack of removing the previous adhesive created a weak bond enabling the wind deflector to become detached. Attached is a copy of the recall instructions which contains no step to remove previous adhesives or check for previous repairs; only the use of alcohol to remove dust or particles. Hyundai corporate followed through on an investigation Case Number #[XXX](December 2024) finding that the recall was performed and they had no ability to investigate the proper method for subsequent repairs. Referring the issue back to local dealerships to apply their own judgement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This event took place on or about [XXX]. A month or two prior, my vehicle had just undergone a safety inspection with over $2,000.00 worth of repairs that were performed with great care, due to noticing loss of power upon acceleration. I'm currently living in Wyoming, and the engine blew while driving on the highway in Colorado, causing a mild underbody fire while driving at high rate of speed. At this point, my safety is of great importance and concern, the radiator had internal damage that was not disclosed by the initial dealership, that took possession of my vehicle. So I truly don't know what or who to believe (which parts have been properly repaired on my vehicle or what has not), it took me to personally tow my own vehicle back to the local repair shop here in Wyoming, and the repair shop could not get power to the vehicle. Eventually the repair shop realized that the original "ground" bolt that "was" on my brand new battery was stripped out of place and replaced with a tapping screw, that's why no power was getting to the vehicle as needed to operate properly. The repair shop also noticed internal damage to the radiator (inside bay) with 2 puncture holes (that was not disclosed at any point of interacting with the dealership. Now my safety is an extremely huge concern. Again, I don't know if the vehicle is in worse or better condition with the most recent repairs that have been done to my vehicle. The engine was confirmed to have been damaged internally and externally "beyond repair". I was never given an exact description of any and all damages "requested by me at the time I called the dealership". My son and I are still without our vehicle, we are in dire need of transportation, and to have our vehicle back and running in a condition that is sufficient to perform for our everyday needs, to get back and forth to doctor appointments, etc. We are in great hopes to get this unnecessary nightmare behind us, so that we can press on with our lives....INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
