A brand-new car with 200 miles on it shouldn't be giving you problems. And if it is, you might want to return it—or at least take it to get checked. That's exactly what happened to one woman's Kia. In a TikTok with more than 248,000 views, mechanic Oliver B. (@olivierb_2.0) films a customer's brand-new Kia that's already throwing a check engine light just a week after she bought it. The car’s dashboard feels like a ticking time bomb. It says, "Vehicle will be turned off automatically in: 26:56." "Swear to god these new cars," the mechanic begins. "Look at this. This thing only has 200 miles on it." He explains that the check engine light came on, so he plugged in to scan the vehicle, only to come up empty. "No codes. Engine good," he says. But something still wasn't sitting right. The motor was sounding off, so he pulled up live data to check for misfires. There was nothing at first, then he revved it up. "There's a misfire right there," he says. "Misfire on cylinder three. Yep, yep." What Causes A Cylinder Misfire? A cylinder misfire occurs when one of the engine's cylinders fails to combust properly, and according to DARCARS Used Car & Service Center, there are a handful of common causes. Worn or faulty spark plugs are the most common culprit, since they deliver the spark that ignites the fuel. Bad ignition coils are another possibility, since they convert low battery voltage into the high-voltage jolt needed to fire the plugs, and a failing coil will take out whichever cylinder it serves.

What Does A Misfire Feel Like? If you've never experienced one, a cylinder misfire isn't always obvious. According to Tires Plus, it can feel like a sudden shudder, a jerking sensation, or a hesitation when accelerating, as if your car briefly forgot how to be a car. At idle, you might notice a rough shake or vibration, almost like the engine is struggling to stay awake. Power loss is another sign, especially under load, like when you're merging onto a highway or going uphill. Fuel economy can tank, too. And while the check engine light is often the first warning, it doesn't always show up right away. We want your opinion! What would you like to see on Motor1.com?
