Some owners of 2010-2017 Buick Enclave vehicles might comment about a clunk/thump noise on acceleration once after each key cycle that might be mistaken as coming from the suspension or engine compartment.
On some 2016 Buick Cascada and 2012-2017 Verano vehicles, the accelerator pedal can break at the stalk just below the housing due to the driver entering/exiting the vehicle with their foot resting on the pedal.
Some owners of 2014-2015 Buick Verano vehicles may complain that the HVAC intermittently only blows cold air at operating temperatures, even when the controls are set in the warmest position.
