Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 3 tested variants for this model year.
Complaints for the 2019 Buick Regal are spread across a handful of systems, with the powertrain drawing the most reports. Owners describe oil leaks traced to PCV system failure, where excess crankcase pressure blows out the rear main seal, often with no dashboard warning lights or fault codes to signal the problem early. A squealing noise during cold weather is one reported symptom. The transmission side sees reports of an intermittent "Shift to Park" message appearing even when the vehicle is already in park, which multiple owners attribute to the shift position switch design. A smaller cluster of engine-related complaints rounds out the picture, along with a couple of reports involving suspension concerns that owners say persisted across multiple dealer visits. Tire vibration at various speeds shows up in at least one report but appears isolated compared to the recurring drivetrain themes.

Total Complaints
By System
The 2019 Buick Regal has 3 recalls, the most serious of which involve brake performance: one affects stopping distance and another can reduce rear braking power, both raising the risk of a crash.
On the brake side, a software error in the electronic brake control module can fail to provide power assist if the vacuum brake system stops working, meaning the pedal becomes significantly harder to press and the vehicle takes longer to stop. Separately, the rear brake caliper pistons may have a coating defect that allows gas pockets to form inside them, which can reduce the clamping force at the rear wheels and diminish overall braking performance. The third recall covers the front seat frames on both driver and passenger sides, where a lower crossbar may have been poorly welded. A seat frame with a weak weld can shift or collapse in a crash, reducing the protection the seat provides to the occupant.
