Buick LaCrosse speed limiting issue with jerking and notification symbol during driving on Buick LaCrosse

Some Buick LaCrosse owners report experiencing speed limiting issues, characterized by messages indicating reduced speed capabilities and limited acceleration. Additionally, some owners have noted a jerking sensation while driving, where the vehicle unexpectedly locks and unlocks, leading to a decrease in speed or a complete stop, suggesting potential underlying problems. Furthermore, warning symbols such as ABS, glow plug, airbag, or supplemental restraint system lights may illuminate, indicating possible malfunctions with traction control or safety systems. To address these concerns, it is advised that owners have their vehicle inspected by a dealer promptly if the speed limiting message persists, as this may be linked to a faulty Wheel Speed Sensor affecting multiple systems.
