Pontiac G6 rough idling and fuel smell inside car with stuck driver's window and shifting issues on Pontiac G6

Some Pontiac G6 owners report experiencing a fuel smell inside the car, which may indicate issues such as a bad gas cap, evaporative emissions system leaks, or an actual fuel leak, and it is advised not to drive the vehicle until the source is identified to prevent hazards. Additionally, some owners report rough idling, potentially caused by a failing throttle body, which disrupts air-fuel flow, and suggest that cleaning the fuel injectors can help restore proper engine operation. Furthermore, issues with a stuck driver's window have been noted, often linked to problems with the window regulator, motor, or electrical connections, necessitating inspection of these components. Lastly, shifting problems are reported by some owners, which may stem from low transmission fluid levels, a faulty transmission control module, or worn-out components, and checking the fluid level and diagnosing error codes can help identify the cause. Promptly addressing these concerns is crucial for maintaining the performance and safety of the Pontiac G6, and consulting a qualified mechanic is recommended if issues persist.
