Between oil change intervals, the check engine light flickered intermittently. I checked the oil level and it was very low. I added 3 quarts of oil and took it to my Hyundai dealership. They performed all the oil consumption tests and told us that the car now burns seven-tenths of a quart every 1000 miles. Hyundai USA claims that this is acceptable oil consumption. I disagree of course. I called my service adviser at the dealership and requested that Hyundai replace the engine because a 2015 Hyundai Sonata with only 70K miles should not be burning that much oil. He agreed and told me to keep monitoring the oil consumption and if it burns 1 quart or more after 1000 miles, to bring it back.
Oil consumption issues. Had a brand new factory motor to replace original motor due to engine failure from oil consumption issues on June 29 2020 at 154,285 miles. The new motor only has 56,665 miles on it and I'm having to add extra oil in between changes because it is bone dry after about 1800 miles from oil change each time.
The vehicle is demonstrating clear signs of engine failure based off the symptoms Hyundai states on its website for the rod knock bearing recall (no power, enters limp mode, white smoke out tailpipes, etc.) Hyundai states vehicle passes testing. Engine also has oil consumption issues, has had its PVC value fail twice in ten months, and burns through 1.5 qts of oil every 496 miles (has failed all 3 consumption tests). The vehicle has stalled out on multiple occasions and risked my/my child's life, has required cylinder cleanings and fuel injection cleanings, and the engine gets extremely hot. This is the second failed engine in the Sonata, and Hyundai has not stated if they will replace it.
After Hyundai Dealership performed RECALL 953, vehicle is having uneven engine idling, especially while stopped at traffic lights/stopsigns and when starting the vehicle. It is noticeable enough that I am concerned the theta ii engine is failing, or about to fail.

My son was driving my car home from work and while waiting at a light, he went to go in the car would not move the engine. He just died right there in the middle of the street on him. He was stuck in the middle of the street for quite some time waiting for a tow truck because it was way too dangerous for him to get out of the car. It was during traffic hour. The car only had like 48,000 miles on it. After repaired by the dealer car started having other issues with the engine light coming on with intake manifold but dealer claimed that part is not covered, which that part is part of the engine that they supposedly replaced.
Insurance companies are not proving insurance because of rise in theft of Hyundai vehicle. Now they are asking to install remote start kit for physical engine immobilizer. Cost of this installation is $350 - $500, Hyundai is not entertaining this issue. Hyundai are saying we have done anti theft software update but insurance companies are saying that is not enough.
Hybrid system warning comes up often and everytime I take it to get assessed, something different is getting fixed. These repairs are all expensive out of pocket repairs. The problems continues to happen and I-??m constantly repairing something different.
Vehicle displayed hybrid warning while moving through an intersection on a highway. The car's engine turned off along with the power steering and brakes. Had the light not been in my favor, I would have been unable to stop on a high speed highway with oncoming traffic.
I am 86 years old. I bought the car brand new so I am the original owner. I have kept the car perfectly maintained and garaged from the day I bought it. My wife is also 86. She and I are the only ones that drive the car. To date, it has 73,822 miles on it. The main issue I am having is random, unpredictable stalling and hesitation when trying to accelerate. We have also had unintended acceleration. This always happens at the worst times which causes grave concern for our safety. We have taken the care to the dealership here in Cape Girardeau, MO called Chris Auffenberg Hyundai. They've charged me $130 only to tell me nothing is wrong. I have continued to try to work with them and they now have decided a new fuel pump will fix this which is $730. I have noticed there are already hundreds of complaints on the 2015 that all say they have the same exact issues I am having but this dealership doesn't seem to care. Here is what I have read. "The most common issue in the 2015 Sonata lies with its faulty throttle control system, which can cause stalling, hesitation, and even unintended acceleration. Currently, there is no fix from Hyundai." My dealership will not acknowledge this even though it is public information. I feel like they are going to keep replacing parts and are taking advantage of me. [XXX] is the Service Manager at this dealership and I am not happy how he is handling this. Please let me know if there is any additional information I can provide. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact's friend owned a 2015 Hyundai Sonata. The contact stated that while her friend was driving at 20 MPH, a motorist informed her that there was a fire visible underneath the hood. As her friend opened the driver-side door, the vehicle became engulfed in flames. The contact's friend was taken to the hospital where she sustained severe burns to the left side of her body. The contact's friend had her skin grafted from the right side of her body to repair the severe burns sustained to her left thigh and ankle as well as other parts of her body. A police and fire report was filed. The vehicle was completely incinerated due to the failure. The remains of the vehicle were towed to an independent tow yard where it was deemed a total loss. According to the fire report, the fire was caused by an unknown electrical failure malfunction; the source of the failure was undetermined. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was destroyed. The failure mileage was 71,820
Car stalls intermittently. When at a stop sign or red light, then when my turn to go I step on gas peddle, car starts to go, then stalls. I have to let off gas pedal and step on it again to get car going. This is dangerous as it leaves me in intersection and vulnerable to oncoming traffic. I had a mechanic check it out and they cleaned Throttle body, but that did not fix problem. No trouble codes showing up apparently.
over the course of this last year I've been in contact with Hyundai motors of America and my local Hyundai dealership after my 2015 Hyundai was showing signs of engine issues i was traveling along i-95 with my child at highway speeds when my car suddenly came to a stop causing panic and what could've been a tragic accident. had I wasn't able to regain control of my car. I was told to schedule an appointment which I did that same day taking my car in for service where I learned about several recalls on my car make and model. I was informed that a update was need along with knock sensor detecting software since that initial contact I've taking my car back to the dealer regarding smell of something burning and excessive oil consumption. my local dealership have since performed Nemours oil consumption test finding issues and picking and choosing what information is being sent up to corperate. I had the service manager tell me Hyundai is not willing to honor the repair unless my car engine brakes down or catch fire which is very likely. the service manager then proceeded to state I would in fact need a new engine eventually. "I have everything documented " which then I contacted Hyundai motors America for a second time and was told to return to dealership where a case was open not once but twice and ended up closed stating Hyundai motors America not honoring the extended warranty on my vehicle. this is very hazardous and concerning cause my car again on 9/15/2023 came to a sudden stop traveling highway speed.

I purchased a 2015 Hyundai Sonata from Carmax on 12/6/22 in Tinley Park, IL. The motor on the car went out on 8/30/23. I took my car to family mechanic to find out that the motor has a hole in the back of it. I had it towed to Happy Hyundai on 9/1/23 in Oak Lawn. I was by Happy Hyundai that they will not be able to look at my car for for 4-6 weeks. Carmax claimed to have did an all point inspection on the car but yet the motor went out. I-??ve only had the car for 8 months. The motor went out while I was driving on the express way going over 50 mph. My safety and others around me was put at risk. Luckily me and no one was hurt. The only time the engine warning lamps came on while I was on the expressway and that-??s when the car started to slow down while trying to get to the right side of the expressway.
