Buick Century acceleration issues and overheating despite sensor replacement on Buick Century

Some Buick Century owners report experiencing acceleration issues, such as the car shaking and struggling to reach 30 mph, which may indicate underlying problems with the vehicle. Additionally, they note slow acceleration from a stop and sluggish gear changes, prompting them to check fluid levels as a preliminary step. Furthermore, some owners report overheating even after sensor replacement, which can stem from coolant leaks and thermostat failures. If the engine heat rises beyond normal levels, it may suggest a more complex issue within the cooling system, particularly insufficient coolant flow. These concerns highlight the importance of regular coolant level checks and seeking professional assistance to diagnose and resolve the specific issues affecting acceleration and overheating.
