With no prior warning lights, motor in the vehicle started making knocking noise and hesitating, check engine light turned on while driving on the freeway. The vehicle has been inspected by central valley Hyundai in modesto ca and they said cylinder 1 & 3 failed in the piston bearings. In a text from the certified technician he said there was nothing I did to cause it. He said when the bearings fail it causes internal damage to the engine, and that my 2016 engine will need to be replaced with only 109,000 miles. This exact bearing failure is a known issue on many other vehicles from Hyundai.

My 2016 Sonata, has 111,500 miles on it and burns excessive oil (4+ quarts every 1500 miles). I have taken it to a local mechanic who has seen this issue with similiar Sonata's. He believes the engine needs to be replaced. I have opened a matter with Hyundai Customer Care (that got me absolutely no where). I have to wait two weeks to get it into my dealership, meanwhile I am afraid to drive it out of safety concerns. I see similiar posts here and see Hyundai doing nothing to take care of its customers.

The problem appeared on December 2020 in the middle of a Hwy 50 East in Washington DC. It was scary and dangerous. First it showed some malfunction sign on the screen and right way slowed down to 40 then 20 then zero. I push the gas pedal but didn't work. I have no idea what to do. I call Hyundai college park dealership agent explained what happened. She [XXX] told me to tow the car and suggested one of their partners tow truck driver. However when I turn off the car and turned on again it worked. The engine started to run. I begun to drive. After some time I took the car to the dealer and told me the car have safety recall. The repaired it and told me it will be ok. But in reality, it didn't. This happened again and again and again. Till this moment the engine continues to stalled in the middle of HWY. I got no solution from the dealership. When ever I visited they give me different issues that I need to fix. One time they said it is fuel pump and another day they said coolant pipe needs to get fixed. I am so tired of keep going to the dealer services. I put my life and my precious kids life at risk all the time while I am driving this car. It is frustration because I got no one to help me and understand why this issue is persistent. I don't want to end up being injured or got killed by an incident that caused by this problem. How awful it can be if a collision happens in the HWY. Driving this car every day with my kids are frightening and hard to imagine what could happen to us. So I am requesting an investigation on this car with the case number I got from the headquarters. Here is my case number [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I was driving my father's 2016 Hyundai Sonata SE, which is spinning a bearing. I was able to drive it home safely. I took it to the dealership and I was told it was out of warranty. Why? Because corporate said the Service Campaign 953 wasn't completed. They sent mail out to my father, but he wasn't home most of the time because he's a Truck driver. We don't open mail for him because he never said to. If we did, we could've been arrested for "obstruction of correspondence." Back in 2019 he shortly worked for Uber but returned back to Truck driving. Before the car failed, It was burning oil so fast that I had to buy a new can every two weeks. Now, my dad doesn't want to fix it. So he's risking his credit and my Apartment's towing it today. The car will be missed, but we will not buy another Hyundai Motor Group Vehicle ever again.

Engine failure before 100,000 miles

- Albuquerque, NM, USA

We have a Hyundai sonata that has been burning oil since 56,000 miles and has failed 5 oil consumption tests.the car is unsafe to drive. It stalls on highway and around town. It just stops running and leaves us stranded. The car now burns 4 quarts of oil every 1,000. We have to put oil in the car every week. The plugs fowl about every 4,000.. Car goes into stall or safe mode. We are afraid to drive the car and it's our only form of transportation. Hyundai just laughed at us. We have all maintenance records and still they won't fix the vehicle. We need help. The care is unsafe to drive because it stalls in traffic and we have almost been hit in the rear many times. This company made bad and defective motors yet our government refuses to protect us.

Engine is consuming oil at a rate of approximately 1 quart every 300 miles. Odometer reads 108,000 miles (approx). Vehicle was put into 'limp mode' while traveling due to severe oil loss. Upon arriving at repair facility, engine was found to be down 3.8 quarts despite having had an oil change 2 months earlier (1000 miles). No leaks have been detected in system. Frequent checks of oil level is necessary, to avoid damaging engine or risking return to limp mode. Have been told this is a common problem with these engines.

Engine lost 4 quarts of oil in a little over 2000 miles after service (2nd event). Engine oil caution light came on with 1 quart of oil left in the engine. Oil dip stick is tarnish brown, evidence of an over heated engine. This car only has 63000 miles on it and I believe it's a danger to drive on any highway. I've visited the dealership which has serviced this car since purchase and they suggest an oil consumption test be performed, which I find unnecessary and to add, the cost of the test could be charge to the customer. I have read of the deadly fires and crashes due to these engines failures due to oil consumptions problems. Recall them all now! There is no room for profit over safety in this situation!!!

While on the interstate highway, there was a loss of motor power, the engine light started flashing, and the car's speed dropped from 70 mph and then would not go above 60 mph. The car would then have trouble shifting gears and getting back up to speed when slowed down, and the entire car would "kick" when it did shift gears. We took the car to a mechanic, who confirmed that the oil was low when it shouldn't have been, and they suspected something wrong with the oil pan (possible leak) and that exacerbated the issues with the engine. Mechanic told me that a replacement would be a required. The car has not yet been inspected by anyone else. The only prior indication that there may have been a problem was that I had to get my oil changed more often than I thought was normal, but my car gave no other warnings, and the engine light only came on when the serious complication arose while on the interstate.

- Owensboro, KY, USA

My cvvt is bad, the car is only 7 years old and has had on time oil changes. I bought the car from the dealership not even 2 years ago, on september 3, 2021. The cvvt is bad already. I do not speed, and I take good care of the car. There is no reason this part should have gone bad on so many cars this far. Please recall this item as it has gone bad on multiple vehicles, as well as my car constantly smells like it-??s burning due to this issue.

- Delmar, DE, USA

Major oil consumption every ~1k miles. Every oil change result in a 1 quart or less of oil when voiding oil tank. No leaks under car, no oil on car port"?"

Vehicle stalled while leaving a driveway. Later the oil light came on but didn-??t stay on while backing out. Upon checking the oil level it was below the low dipstick line. It took 3.5 quarts of oil to get it back to within proper dipstick range. No oil burning out exhaust and no oil leaking under the vehicle.

Motor burns oil knocks and is loosing power while driving. Constantly having to add oil between oil changes. When trying to accelerate car starts to sputter on highway. Can't get power to engine and bad rattle sounds

- Pleasant Hill, NC, USA

Car has less than 67,000 miles on it. Routine oil changes using 5W/20 Valvoline full synthetic oil. Approximately a year ago at less than 60,000 miles there was a noticeable difference in performance...especially when accelerating. Tried couple tanks of premium unleaded, but that did not help. I noticed significant oil usage...but no oil leaks. Within 1,000 miles of an oil change, I was having to add more oil. The oil usage is getting worse...now having to add a quart about every 600 miles. I have enjoyed this car very much, but I'm deeply concerned about the amount of oil it is using. I am the second owner so there's no warranty. After researching the issue, I see that many people are experiencing this exact same issue with their Hyundai. If Hyundai Motor Company wants to remain a viable company, they need to do the right thing and recall all these cars to be repaired.
