Bought in 2023 @ 98k miles. Have had trouble with 1. It would only start in drive, then that seems to have self corrected. 2. In drive, car would not accelerate properly, and would slow as though I was braking, but no foot on brake. Had rear brake sensor replaced, seemed better for a while. 3. Developed oil leak at 120 miles which valvoline characterized as "not serious. . . Just keep checking it and topping it off. " so, have been doing that. Today after oil change, it began running rough, lots of vibration, then the shifting problem, sluggishness, and new. . Smoke from under hood on driver's side. No check engine lights at all. Nothing registered as hot or overheating. Turned off car, checked oil and trans fluid, both in proper range for warm engine. Let car sit and cool for an hour. Decided I had parked too close to the propane tanks for a smoking car, so I decided to start car just to back it into a space across the lot. Car had no issues- no smoke, no jerking or vibration, no sluggishness, no phantom braking. This car has done this same thing about once every 6 months since I've had it. Changed a tire sensor, that seemed to fix it once. Stopped using cruise control altogether, that seemed to help once. My brother is an ase certified high school auto mechanics teacher who ran his own shop for 20 years and worked on trucks for vdot for another 7 years and he cannot diagnose it. I know it has something to do with not being in the correct gear, but it's not reliable, and I have a hard time believing it's just my vehicle.

I was driving on the highway when my car threw a crank rod. In doing some research I see that this has happened on numerous vehicles having faulty bolts on the crank rod cap. There has been no recall but is an ongoing issue with many owners.
Oil light never came on, however no oil was in vehicle, took to southern auto mart in georgetown, SC they said it was okay, they changed my oil. Two weeks later no oil, engine is no good.
I was driving my car and, according to my mechanic, the crank rod came loose. I bought this vehicle used so the Hyundai 100,000 mile warranty will not cover it. I have done routine oil changes and up to this point had no real problem with the vehicle. It is disappointing to say the least as I have had this vehicle for about four years and purchased it based on the idea that Hyundai's are supposed to be reliable vehicles. I had hoped that Hyundai would have done something to help remedy the situation but at this point they have not, which is also disappointing. In the future I will not be purchasing a Hyundai.
