NHTSA 5-Star Safety Rating
Engine complaints lead the 2020 Buick Enclave's complaint record, with owners most often describing oil consumption between oil changes, some reporting needing to add a quart or more before the next service interval. A related pattern involves exhaust symptoms: multiple owners describe a cracked or leaking flex pipe bracket, with ticking or rattling noises under the hood and exhaust odor detected inside the cabin. In at least one case, the flex pipe issue was linked to catalytic converter damage. Electrical complaints are the next most-reported category, with the backup camera failing to display an image when shifting into reverse being the most common symptom. A smaller group of owners reports transmission or drivetrain behavior, including the vehicle unexpectedly engaging a park or shutdown state while in use.

The 2020 Buick Enclave has 7 recalls, the most serious involving a fuel pump defect that can cut off fuel supply to the engine and cause a sudden stall without warning, and tire defects that can cause sidewall failure or sudden tread loss at speed.
The fuel pump's internal nozzle can become blocked, starving the engine and causing it to stall unexpectedly in traffic. The tire concerns cover two separate filings but share the same core problem: Continental tires installed on certain vehicles may have been overcured during production, which can cause a structural break in the sidewall and sudden air loss, or a belt separation that sends tread flying off the tire while driving.
On the drivetrain side, the automatic transmission's start-stop accumulator may be missing bolts on its end cap, allowing transmission fluid to leak out. If enough fluid is lost, the transmission can lose the ability to send power to the wheels, leaving the vehicle unable to accelerate.
The frame has a structural concern that appears in two filings but describes one problem: a crack in the right-hand frame rail inside the engine compartment. A cracked frame rail weakens the front structure of the vehicle and reduces its ability to manage crash forces properly in a frontal collision, raising the risk of injury to occupants.
Rounding out the list, the roof-rail curtain airbags have a concern with a component called the diffuser, which directs gas into the airbag during deployment. If the diffuser was not properly crimped to the inflator, it can break free during a crash, reducing how well the curt
