The Buick Regal is a line of mid-size cars marketed by Buick since 1973. For nearly its entire production, the Regal has served as the premium mid-size/intermediate offering of the Buick product range. Introduced as a submodel of the Buick Century, the model line is currently in its sixth generation. From the 1970s to the 1990s, the Regal served as the Buick counterpart of the Pontiac Grand Prix and Oldsmobile Cutlass Supreme.

Originally introduced as a personal luxury coupe, the Regal was later expanded to a full model line. To showcase its success in NASCAR racing, from 1982 to 1987, Buick introduced the Buick Regal Grand National, Regal T-Type, and the limited-production Buick GNX. During the 1990s, while the four-door sedan superseded the two-door coupe entirely, forced-induction engines made their return, with superchargers replacing turbochargers.

For 1999, the Buick Regal inaugurated the sale of GM vehicles in the Chinese market, with the 1997 design lasting through 2008. Following the 2004 model year, Buick retired the nameplate in North America, with the Regal replaced by the Buick LaCrosse.

For 2008, Opel introduced the Opel Insignia as its largest sedan, with Buick rebranding the model line as the Regal for the Chinese market. For 2011, GM reintroduced the Regal to North America, rebranding the Insignia sedan for North America. For 2018, Buick introduced the second-generation Opel Insignia, sourcing all production from Germany; alongside a first-ever liftback sedan, the Regal TourX was the first Buick station wagon in 22 years.

After 2020, as the division shifted away from car model lines, Buick ended sales of the Regal in North America.

Common 2020 Buick Regal problems

Common Problems with the Buick Regal 2020

Timing Chain Issues: The timing chain is a crucial part of the engine, responsible for synchronizing its operations. When it experiences problems, the vehicle's performance can be significantly affected. Symptoms of timing chain issues may include unusual noises from the engine bay or a general lack of engine efficiency.

Ignition Key Stuck: Issues with the ignition system, such as the key getting stuck or refusing to turn, can be particularly frustrating for drivers. This problem could stem from the ignition lock cylinder or be a symptom of a larger electrical system issue.

Power Window Failure: The failure of power windows to open or close is not just a matter of convenience but can also be a safety concern. This failure typically arises from faulty window motors, deteriorated regulators, or electrical issues within the door’s wiring.

Brake Failure: Certain models of the Buick Regal, including some from the 2020 model year, have been recalled due to issues with the power brake assist. These problems can cause affected vehicles to exceed Federal Motor Vehicle Safety Standards for minimum required braking distances, increasing the risk of a crash.

Tire Pressure Issues: The tire pressure warning light on the dashboard indicates that there may be an issue with one or more of your tires – the air pressure is too low, too high, or you have a slow leak or flat.

Anti-lock Brake Issues: The anti-lock brake warning light indicates that there's an issue with your anti-lock brakes. It could come on for a variety of reasons, from a faulty speed sensor to low brake fluid to total brake failure. Better get it checked out!.

Please note that these issues may not affect every vehicle of the same year, make, and model. Use your VIN or plate to find out if your specific car has open recalls.
