Volkswagen Passat unable to accelerate above 20 mph after 30 minutes of driving at 40 mph on Volkswagen Passat

Some Volkswagen Passat owners report experiencing acceleration issues, specifically being unable to exceed 20 mph after driving at 40 mph for 30 minutes. This problem may stem from restricted fuel or air filters, which can impede proper fuel flow and air intake. Additionally, some owners notice jerking when pressing the accelerator, indicating a potential misfire that could be affecting performance. Transmission problems, such as hesitation during acceleration, may also contribute to this issue. Furthermore, a malfunctioning throttle motor can lead to difficulties in transitioning from lower to higher speeds. To resolve these concerns, it is advisable for owners to inspect filters for clogs, diagnose any misfire issues, check the transmission system, and evaluate the throttle motor to ensure proper functionality.
