   car had an engine knock at 110,000 miles and took it to a repair shop and said they are pretty sure it was an engine rod and that the whole engine needed to be replaced still waiting to get it to the dealership to see what they are going to do due to this car being a leased car and it will not run anymore.

   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 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…

   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).

   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…

Check…

    Prior to 100,000 miles, I noted knocking in the engine, especially while going uphill. The knocking would appear and disappear, possibly with oil change intervals. No check engine light ever appeared. After 100,000 miles, the engine progressively began knocking, losing power, and eventually stalling on the road occasionally. I have had to put on my hazards and restart my car. One time, I was barely able to pull over to the side. Again, no check engine light ever appeared. I…
