2017 HYUNDAI SONATA Complaints

My daughter wrote you earlier this week about the severe oil oil usage of her 2017 Hyundai Sonata. I am writing a follow up because I co-signed for her vehicle when she and her children were deserted by her husband. Since my name is listed first on her vehicle title and bank loan I have a special interest in the problems she is experiencing with her Sonata. She indicated in her filing with your department that she has had her local Hyundai dealership change her oil every four to five thousand miles which is true. The last time the oil was changed by the dealership was around [XXX]. When she spoke to the service department last week she was informed that since the VIN was not listed as being part of a recall there was nothing they could do for her. Yet this past week I put four additional quarts of oil in the engine. She and her children live with her mother and me. I can attest to the fact that there is no smoke from the exhaust when the vehicle is idling which would indicate bad valve guides. Nor is there smoke from the exhaust when the car is being driven on the road which would be caused by bad oil rings on the pistons. There is no oil being dripped on our driveway or garage floor which would indicate gasket or seals leaking, but the car is consuming oil at an alarming rate and we need your assistance with this issue. Thank you for your time. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine has been burning oil I kept taking it to Hyundai to get it repaired and do the trial test to get it fixed they refused to repair. Engine has now blown I would like my car repaired I want to keep it. If possible

Twice in the past two months the vehicle enters a rough low RPM. Will not respond to the accelerator and the engine shuts down. First was in a parking lot the second while driving in school zone traffic. Was able to safely get off the road the second time. The parking lot I waited a few minutes and the engine ran normally. Same for the second time, waited a few minutes and it would not start then a few more minutes it started and ran. Both times all dash warning light lit up but just for a few seconds. If this happens at highway speeds a good outcome seems risky.

Last week as I was driving the engine oil warning light came on. I pulled into a parking lot immediately and turned off my Sonata. After a few minutes I checked the oil and found no oil on the dip stick. I added oil and returned home where I checked online and discovered that there was a recall for Hyundai Sonatas using or burning excessive amounts of oil and ruining the engine. I called my local dealership and was told that my VIN is not included in the recall. It cost thousands of dollars to repair or replace an engine. How could my VIN not be included? The dealership offered no help. I go to the local dealership to have my oil changed every four to five thousand miles.

THE ENGINE WOULD BURN UP OIL NOW CYCLINDER 4 IS NO LONGER PROPERLY WORKING AND I NEED A NEW ENGINE. STARTED IN AUGUST 2023, NEEDED SPARK PLUGS AND FUEL LINE REPAIR.

I was driving the vehicle with 2 other occupants onboard on [XXX] towards US-101. The EPS warning light already came on after entering [XXX] from [XXX], but initially, I didn't think it was much of an issue. As I merged to the right lane in preparation of entering the highway, the steering began to feel very stiff, so I immediately made a right turn into a local street when there was a little bit of steering left. As soon as I pulled over, the steering locked up completely, and both the EPS warning light and the dash display's lane-departure system warning were activated. Luckily no other vehicle or humans were endangered at the time. I put the car into park and powered it off. When I powered it back on again several minutes later, the issue resolved itself and I was able to continue driving with normal steering, and steering remained normal after several power on/off cycles which included both local and highway driving. Come to think of it, ~3 months before this incident happened, I already noticed occasional stuttering of the steering wheel and humming of the EPS assembly when the car is stationary or at low speed. I took the car to a third-party repair shop on the next day since the Hyundai dealership appointment is a week away at the earliest. They ran diagnosis before telling me that the steering sensor in the EPS motor assembly failed, and this happened very frequently for 2017 Sonata Plug-in hybrids. This happens so often, apparently, that Hyundai issued service bulletin [XXX], but this very much looks like a recall to me, as when the system fails, steering is lost completely, and could cause great harm to myself as well as the occupants onboard, not to mention other vehicles around me. I was lucky that it happened before I entered the highway and also had a place to pull over. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I'm reporting the growing concern of my engine having rod knock or seizing . It has been burning excessive oil since I bought it at 80k miles. I have reached out to hyundai and they have denied me any help as the vehicle is past their 10y/100k mile warranty. Although my vehicle has extended warranty up to 150k miles for engine seize or rod bearing failure through them. There's no warning lamp but the piston slap noise is getting louder, I'm scared this problem might leave my family and I stranded in the middle of the night. Also scared that it can catch on fire due to almost running with no oil. I have to do my oil change every 1200 miles, instead of 3000. corporate hyundai has denied any type of assistance, I went to a dealer to get it checked out and they insist without proof of oil changes there's nothing they can do, i do them myself on all my cars and I'm VERY on top of my maintenance. I have scheduled an appointment 02/07/2024 to try and diagnose the growing issues with the engine itself.

Engine went in for the second oil consumption test on 6/17/23 where Hiley Hyundai did not record the correct mileage they put that mileage at that time was 123,893 when it should have read 126161 ( which was 4k miles more than the time of this report) than that therefore it lead Hyundai to believe that the engine was not burning oil and we was in the write mileage due to human error we was denied a new engine and because this is the only car that we have at this time and Hiley has no loaners and we are in CH 13 Bankruptcy we do not have the funds to rent car out

had the oil consumption test done it failed and has been putting oil into the engine every 1000 miles or less due to engine burring up the oil had Hiley Hyundai due and oil change on 6/17/23 had to add 5qt of oil to engine on this day

Engine went through 5 qts of oil and had to refill on 8/31/23 had the oil changed by Hiley Hyundai on 6/17/23 they entered the wrong mileage during the engine consumption test
