The engine consumes extraordinary amounts of engine oil. At 72,000 miles, over 70% of engine oil is lost between an oil change range of 7500 miles. Radiator fluid levels drop as well. I believe the engine has internal problems that lead to engine oil and radiator fluid to enter the combustion chamber. This has been the case since very early days and was also reported to us by other service centers. It has gotten worse over time.

The car suddenly lost power during the city drive, by the same time, engine light was on. The acceleration pedal does not work properly, (envn with the pedal all the way to the floor, it is around 30K RPM with ~30 mph, and the car didn't running smoothly (hesitate to move). Shut down and start again. Everything is back to normal, just the engine light is still on. This is recurring problem, it is been the fifth or sixth time start from the second of the ownership (~8000 miles). Everytime take the car to dealership, they told me did not find anything wrong and car computer was updated (I guess they mean the engine light code was cleared)

My vehicle rattles and knocks all the time. It has a little over 65000 miles and has done this for years. I have taken it to the dealership and told it supposed to sound like that. The car has no power what so ever climbing hills and my gas mileage keeps going down. I have heard this is a common problem but I want it fixed as I dont fee this car is reliable as it has quit running one time before because of this problem. Something needs to be done before someones car cuts off and causes an accident and someone get killed. It does this anytime you give the car throttle. The second thing is the poor stitching in the leather seats. My seats started coming apart at the seams and the dealer says its not covered under warranty but I purchased a full 10 year 100000 mile warranty. This is poor materials and workmashipl I drive the car about 14 days a month and it shouldn't already have a coming apart.
Engine tapping, knocking noise by the pistons Hyundai recall for software upgrade then two months later engine went into protection mode max speed only 57 mph so they change knock sensor then 5 days later back to Hyundai with same problem engine running in protection mode with the blinking engine light again this is the third time. Knock sensor worked find the first time because something happen with the knew one. The car was in motion on every case engine is no good.
The contact owns a 2015 Hyundai Sonata. While driving, the vehicle lost power and made a knocking and ticking noise. The noise occurred from the engine during acceleration and the check engine warning indicator illuminated. The contact was able to drive the vehicle home. The following day, the vehicle was towed to napleton Hyundai of carmel (4200 E 96th St, indianapolis, in 46240, (844) 729-4217) where it was diagnosed that code: P1326 (knock sensor activation) failed and needed to be replaced. The technician replaced the knock and torque sensors. After the vehicle was repaired, the check engine indicator illuminated again. The vehicle was taken back to the same dealer and the engine was replaced; however, the check engine indicator continued to illuminate. The vehicle was taken back to the dealer where unknown parts were ordered and replaced on the vehicle. The manufacturer was made aware of the failure and provided case number: 16277030. The failure mileage was approximately 51,000.
On October 8, 2019, I was driving on hwy 285 in Georgia, when my Hyundai Sonata began to reduce its speed despite me pressing the gas. As I attempted to get to safety, a warning light flashed 'transmission hot..stop'. there was no warning other than that light that popped on at that moment. While driving through an intersection my car completely turned off. I made several attempts to restart with no luck. There was no prior warning and I maintain regularly oil changes. I had to have the vehicle towed to a local Hyundai dealership, where I was told that my motor/engine needed to be completely repaired. When I asked what the cause was, I was informed that my 3rd piston had exploded and damaged the motor to the point of needing replacement. The mechanic stated that it was not know why this occurred. I was also instructed that the manufacturer was no longer making the motor that I have in my car and I would not to purchase a used one. This would cost me approximately $5000 at the least. I have only had this car for less than two years and requiring a new motor is unbelievable. The mechanic shared that I was lucky that the car did not catch on fire while I was driving it.
At 45,800 miles my Sonata could not reach 60 mph and the RPM could not reach 2000. I also noticed the gas mileage drops the Sonata had 35,000 miles on it. I took the car to the dealer and was told it needs new engine.
While driving 30-40 mph the car turn off.. for no reason.. I have always done maintenance on the car from dealership. Just put in a new battery.. and car turn off.. this has happened 2 times
I've been having an oil consumption issue on my vehicle. I've been getting my oil changed on time regularly & the oil seems to burn off extremely faster than it should. Every time I get my oil changed I've been told that there aren't any leaks. Now my check engine light is on & my engine is shaking. Ive only had my car for 3 years & my air bag light came on out of no where. Also my gear shift seems to lock up & wont release from park to drive
We purchased our 2015 Sonata limited in June of 2018 with just shy of 59K miles. In August of 2019; and at 66K miles; our vehicle started producing a knocking noise; with a flashing "check engine" light; and would not accelerate. Since August of 2019, our Sonata has been in the dealership service department 3 times; and for a consecutive 30 days. We were told with the first time in the shop that the vehicle needed a new sensor; which was repaired within a day. When my husband returned to the dealership to take the car home; he barely made it a mile from the dealership before the car started repeating the same issues. The vehicle was immediately returned to the dealership for repairs. The second time we picked up the vehicle; we made in nearly 20 miles back toward home before the car died again. The third time into the dealership; and they finally determined that the engine had failed and required replacement. During this whole mess, we learned that we were experiencing the catastrophic engine failure that is associated with Hyundai's defective 2.4L theta II engines. We have brought this to the attention of Hyundai motor America. They originally offered to buy it back for $4K less than we owe on it; and continued to move us from one representative to the next. As of today, Hyundai has suddenly changed their mind and refuse to buy the car back. Hyundai has produced an unsafe & defective vehicle; prone to potential engine fires; engine failure; transmission issues; seatbelts that don't function properly; and power steering issues. Hyundai refuses to take full responsibility for their unsafe & defective product. We no longer feel safe driving the vehicle (which is still in the shop, btw); and no longer trust it to be reliable.
I must start by saying that english is not my first language, Korean is and I would like a translator when I am called for reference. On 07/16/2019 I purchased a 2015 Hyundai Sonata from carvana and have run into the following problems: The battery was not the correct size for that model car, the engine air intake was completely missing, and the supercharger blew up 4 days after I bought the car. I have sent an email to carvana but never received a response. I have more documents pertaining to this matter that are too large to attached and will be able to send them via email.
Driving my car on the hwy and totally lose all power and im driving 70 mph....lucky no one was behind me at the time but this isn't safe at all...this is my second Sonata that this has happened to and im really afraid to drive these cars... also the car started smoking under the hood.
I purchased my 2015 Hyundai Sonata recently with only 46K miles on it. After 3 weeks, the engine started clicking loudly and it literally sounded like a roller coaster being pulled uphill when under load. A week later the ticking was constant. My husband changed my oil and strained it, finding small metal fragments in the oil. These fragments are from an engine defect that Hyundai even admits having. Now as the second owner, I have no service records prior to ownership and my warranty claim was denied because of it. How can this be happening" Hyundai admits defect but are still allowed to rip off consumers with bad engines" the gdi Hyundai engines are defective and it cost me $3,000!
Hi NHTSA, I drive a 2015 Hyundai Sonata and followed all the recommended maintenance. I started to notice my oil level was below low after 2000 miles at 47000 on the vehicle. I thought it was not filled correctly and had my mechanic check it. Also, I told my Hyundai dealership in laurel, md about the finding. I decided to top off my oil and closely monitor the status. On my next oil change, after 2000 miles my oil was low again. I add roughly 1.5 qts to top it off. I brought my car until Hyundai for an oil consumption test. The mechanic did not note how much oil he started as the baseline; however, the dip stick was over the full mark. After 3000 miles, my oil was at the low level. Per Hyundai owner manual, I can drive 7500 miles between oil changes with non - extreme driving. Hyundai stated my car was not consuming oil, and this is normal.
On or about 3/15/2015, purchased a new 2015 Hyundai Sonata. Maintained oil changes in accordance with "normal maintenance schedule" as described in owner's manual. In 5/2019, while driving on a highway, vehicle began sputtering, knocking and engine light came on. Was told engine "threw a rod" and punched a hole in the engine and now engine needs to be replaced.
The check engine light is illuminated and when coming to a stop, the vehicle lunges/surges forward as if the brakes are failing and I'm going to hit the vehicle in front of me. I took the the vehicle to 2 local jim click Hyundai dealers, the fault code is P200A and they stated the issue is most likely replacing the intake manifold which would not be covered by the powertrain warranty and my mileage is 85,000 presently. I would think that it would be a warranty item because the intake manifold is bolted to the engine and connected to the engine with wires. Now I'm stuck with a $1000 repair bill.
