NHTSA complaints for the 2019 Buick LaCrosse, grouped by the part owners named. Open a row to read what goes wrong.
Hesitation under acceleration is the main safety concern. When the driver presses the pedal to merge onto a highway, nothing happens, and the pedal has to be pumped before the car responds. The report describes repeated episodes and near rear-end collisions, and the dealer says Buick has no fix. A separate, less serious complaint describes a loud sound of water sloshing under the dashboard. It comes and goes over days and shows up at startup or after several miles of driving. A mechanic found the coolant level fine. Only 2 complaints are on file.
