I purchased a 2018 Hyundai Kona, and it has had one major issue after another. It burns an excessive amount of oil, the engine misfires, and now the turbocharger is failing. I’ve already spent approximately $2,300 repairing the air conditioner and engine, and I can’t afford thousands more in repairs.

The contact owns a 2018 Hyundai Kona. The contact stated that while driving approximately 20 MPH, there was a loud clunking sound coming from the engine bay, followed by grinding gear sounds. The vehicle lost drive power, causing the driver to coast over to the side of the road, where the vehicle eventually stalled. The vehicle was towed to a certified mechanic who diagnosed that the timing belt had failed, and the cam gear rod had sheared off inside the exhaust camshaft, which caused the timing belt to jump and the cam chain tensioner to fracture. The vehicle was repaired. The dealer was contacted, and it was confirmed that the vehicle was not included in a recall. The manufacturer was made aware of the issue, and it was confirmed that the VIN was not included in a recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 123,000.

The vehicle suddenly stalled while driving on the highway at normal speed without warning. The engine lost power completely, creating a dangerous situation and a risk of collision with surrounding traffic. The vehicle had to be towed to a repair shop, where the issue was diagnosed as engine failure. There were no warning lights or prior symptoms before the incident. This appears to be a serious safety-related defect. I am aware that similar engine issues have been reported in Hyundai vehicles.

The check engine light came on while driving. Vehicle was assessed by mechanic with strange diagnostic code; full oil and filter change done. Check engine light still on and engine stalled while driving on freeway. Took to dealer and was advised the car requires CVVTS (which is essentially a new engine), serpentine belt and spark plugs (approx 3600). There is a known engine defect with the 2018 Hyundai but they refuse to do as a recall and refuse discounted repair on a vehicle that 8 years old with 92,000 miles. This vehicle is owned by my young adult child and I believe it is undriveable since stalling at full speed is quite dangerous.

The Kona barely wants to accelerate and stalls out while driving. Even though I recently got a oil change there’s oil consumption and the oil is black as if I never got a oil change. I took it to a hyundai dealer ship, i told them what was wrong they said it’s the timing belt. When that’s not the issue. I recently took it to a mechanic to get a third opinion and to see and fix what is wrong. He declined fixing it saying there’s more to it that is wrong and looks like there’s an engine defect and even complained that the oil was so black. I told him that doesn’t make sense because I’ve been getting my oil consistently. He couldn’t fix it. So now I’m stuck with a vehicle that barely drives and stalls out while I’m on the road and it keeps burning more oil. No one knows what is wrong with it.

Incident: January 23, 2026 · Filed: February 16, 2026

The car was burning through oil every 14 -21days. Car has been jerking and taking a while to accelerate. Went to machine to see what’s going he suggested I go to the dealership because there’s no leaks visible. But added more oil so I wouldn’t go without oil there was nothing available for me to come in right away and before my appointment my car started to speed up out of nowhere then completely slowed down then jerked until I could find a safe space to pull over. Check engine came on and the code was reading a misfire. Got a tune up still reading as a misfire now just stuck at the dealership playing guessing games with what’s wrong with the vehicle.
