This car will not start when it is cold. I have only had this car for over one year and four months. The car ran perfect up until we began to have extreme cold weather. This is so dangerous because it could be an emergency and my car will not start. I have done my research and discovered that this is an ongoing issue with Hyundai. And nothing has been done about it.

For the past 3 Oil changes, I find myself having to add 5 quarts of oil to my car after driving over 1,000 miles from getting my oil change. This third oil change I have added 15 quarts of oil to my car due the check oil light comes on. When I first purchased this car in March 2021, I didn’t experience this issue. I’ve never had to add oil to my vehicle before an scheduled oil change. Whalen the oil is checked due to the light coming on, it’s boned dry.

My car started leaking oil from the oil drain bolt area. I took it to the dealer and they said the oil pan had a defect, they called it a “weld crack”. A quick internet search shows that this is a very widespread issue.

My car was serviced at Hyundai dealer for other problems while my car was being serviced the service department said they fixed a recalled latch on trunk I never had problems with trunk before the so called recall was fixed Now my trunk is stuck close and pops open and is very hard to close once open you have to slam it shut once shut it will not open I had a tail light out I press the button to open the trunk and after riding around for Three Days it popped open and I fixed the tail light within 3 weeks the tail light is out again and my trunk is still stuck shut I called the dealership and it’s seems as though it’s not important and been giving appointments so far away

Loss of power on highway or during normal driving possibly due to oil pan assembly according to odi 11481745. This has cause near-miss accidents on highway on ramps a number of times. Separate issue, when the outside temp is at our below 30°F the starter can fail to turn over resulting in a car that won't start even with jumper cables applied.

Purchased Certified Used 2018 Hyundai Sonata in March of 2021. Engine oil light came on at 36,863 miles in July of 2021, and I took car to repair shop. I was told that these cars (2018 Hyundai Sonata) excessively burn oil -- though under 60K miles was "early" -- and that it would need to be constantly monitored. Car went through four quarts of oil before next oil change at 42,437 miles. Took car to local Hyundai dealership and was told there was a "crack in my oil pan" (though there were no oil spots in my driveway or garage that would point to an oil leak from a pan). Pan was replaced. Engine oil light came on again (despite problem being "solved") TWO MONTHS LATER AT 44,129 miles. I put a minimum amount of oil into the engine and drove over to dealership to have issue resolved. They told me it was sparkplugs, which they replaced. Checked oil level at each gas fill up. Car went through FIVE quarts of oil before oil change at 47,432 miles!!!! Five quarts in 3,000 miles. Dealership now states I must get approval from Hyundai to do an oil consumption test.

White paint has started to peel off the body. Vehicle is past warranty (>3 years, >36,000 miles) and Hyundai refused to deal with it. It has been a known problem that their pearl white paint easily peels off the body down to the steel but they refuse to issue a recall for it.

The contact's son owned a 2018 Hyundai Sonata. The contact stated while her son was driving at 68 MPH with a passenger in the front passenger seat, he noticed a burning odor and he noticed smoke coming inside the cabin through the AC vents. There was no further information provided. The contact's son pulled into a gas station and saw fire underneath the hood. The contact's son and the passenger immediately exited the vehicle. The contact's son was able to extinguish the fire with the assistance of bystanders who used fire extinguishers. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The vehicle was then repossessed by the auto financing bank. The manufacturer was notified of the failure and informed the contact that they could not assist as the failure was caused by a missing oil cap. The failure mileage was unknown.
