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.

ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION:SUMP/TANK:DRAIN PLUG
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.

ENGINE
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.

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.

We drive a 2018 Hyundai Sonata with Hyundai Quartz White Pearl (W8) paint. It has 62000, so just out of regular warranty. Last week I noticed that we were missing a huge chunk of paint on the roof. As a regular passenger of this car, neither of us noticed anything wrong with it until it was gone. It looked like it just bubbled up suddenly and peeled off. We took it into our local Hyundai Dealer and they told us it was out of the 36k mi. paint warranty. They didn't even look at it. We paid for an extended warranty because they served us so well on our other Hyundais up to that point. I called the consumer line like they suggested and found no recalls. When I tried to get a human, I was met with silence. No indication that the call had gone through. I went next door to there collision center and got an estimate anyway. The man there didn't have to see any more than one picture to know that it was a Hyundai. They service multiple of that owner's various different branded dealerships. Obviously, this wasn't his first rodeo with this problem. He quotes $1200 to put a bandaid on the problem. However, there are numerous incidents of consumers facing the same issue with there Hyundai/Kia vehicles. I have a friend who had the same problem on a similar year Acura with pearl paint. I'm filing this complaint because it is obvious that Hyundai/Kia are not going to own up to this. The first class action suit was dismissed and the problem persists. They are still using the paint to this day and the same delamination problems keep appearing. I do not want to be driving down the road and have a huge slab of paint fly off and hit someone else's windshield. This issue needs to be investigated before someone gets hurt, not after.

The incident occurred within my garage when I attempted to start my car and the starter went out producing a burnt smell and spark within motor. After letting the car cool down I put the car in neutral and had it towed to the nearest garage. I thought vehicle could have started a fire inside my garage and home. I have contacted the manufacture and initiated a case incident report awaiting a call back from Hyundai motor company. There were no waring lights or issues with the car the car before incident. The vehicle is under warranty but the dealership stated, they could assist since I took the car to a garage and had a mechanic work on vehicle. The disposition was the vehicle had a faulty started starter, but this incident has a huge safety flag.

FUEL/PROPULSION SYSTEM, ENGINE, VEHICLE SPEED CONTROL
Engine takes a long time to start up, about 10-15 seconds of pushing the start button starts engine which is probably not good for the car. Also, the car jolts/ wants to stop while driving. Has been an ongoing issue since the week of 9/5/22. Loss of motor power issue sounds like what is going on with my 2018 Hyundai Sonata vehicle.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
My 2018 Hyundai Sonata GDI Engine stop working while I was driving on the freeway without a warning prior to the issue. It never gave me a heads up in advance that the engine needed service. No check engine light to alert me that an issue needed attention. I learned about the engine problem when my engine stop working while I was on the freeway. I heard a loud noise coming from the engine and within seconds my RPM started going down and my car started loosing power while I was driving on the freeway. At the same time my check engine light came on and it was flashing. At that moment I realize something bad was happening with my motor. The check engine light was not on before that. It never alerted me before that, and when it came on flashing on and off it was already too late because my engine was dying and it died and didn't turn back on after I pulled over in the side of the freeway. I was so scared. The cars where going so fast and very close to my car with little room to pull over. The high velocity of the others cars where making my car cradle from the wind. It was so terrifying for me and my little dog i had with me. My seat belt stop working a few weeks before my engine died, and the thought of me getting hit by another car without a seat belt on. I've never been scared for my life like I was on that day. Hyundai dealer sold me a car with a bad engine. I was putting atleast 1 quart of oil every other week sometimes every week in the past year until just recently. I've only had it for 3 years since I bought it and I was putting 1 quart of oil every month in the beginning and with time the consumption of oil increased and increased more with time. Hyundai service my car for an oil gasket last year that should've been cover under warranty, but made me pay for it. I made it aware to them about the excessive oil consumption and told them it wasn't normal how much oil the car was consuming but they denied to service my car under warranty.

SEAT BELTS
The passenger side seat belt locks up. It can lock up immediately when putting it on or it can lock up if I just lean a little bit forward. It will get tighter and tighter to the point where it is very uncomfortable. I have to unhook the seatbelt and re hook. Sometimes this takes many attempts. This is scary when you are going down the highway at 65mph. The dealership has replaced it twice. They were able to see the problem because my husband drove straight to the dealership once when it locked up on me. The last time they replaced it, no one was in the passenger side until we were leaving for vacation. We didn't even get out of the garage when it locked up again. The dealership was reluctant to replace it. They said all seat belts lock up! Because of Covid my husband and I haven't driven much. Once we started going out again we became aware of the problem.

On May 03, 2022 at approximately 3:30pm I was traveling southbound on Arizona State Route 101 in Tempe, Arizona. I was going about 75 mph, and without no warning my car shut off. I had to pull off to the shoulder of the highway to avoid being struck by other vehicles, and also incase I lost control. My Hyundai picked up nails on 3 of the 4 tires in the process. I barely avoided a fatal accident due to the defect, which I had no idea about.
