Kia Sportage high RPMs during acceleration without vehicle movement issue on Kia Sportage

Some Kia Sportage owners report experiencing high RPMs during acceleration without the vehicle moving, which may be attributed to several factors. These include engine misfires that lead to RPM fluctuations, shaking, and power loss. Additionally, some owners have noted acceleration issues where the RPMs shoot up before the vehicle actually accelerates. There are reports of the car feeling like it goes into neutral, resulting in increased RPMs that eventually return to normal. Concerns have also been raised about sudden acceleration during maneuvers, such as reversing at a drive-up window, and intermittent acceleration stalls that could endanger drivers. Cold weather effects, such as diesel thickening, may also contribute to these acceleration problems. Furthermore, some drivers have experienced juddering without an apparent cause, even after brake component replacements. Diagnostic challenges persist, as dealerships often struggle to replicate the issue or identify diagnostic codes, complicating the resolution process. These issues have been reported across various Kia Sportage models, indicating a potential recurring problem.
