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 During the 1990s, while the four-door sedan superseded the two-door coupe entirely, forced-induction engines made their return, with superchargers replacing turbochargers.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 2010 Buick Regal problems

The Buick Regal, a midsize car produced since the 1970s, has been known for some recurring problems that have affected various model years. One common issue is the key getting stuck in the ignition, which is caused by a faulty spring within the ignition switch. This problem has been reported in models made from 1994 to 2016, and it prevents drivers from starting their cars.

Another issue that affects the Buick Regal is related to the mass air flow sensor (MAF) and crankshaft position sensor (CPS). The 1994 to 2004 models of the Regal tend to develop issues with these sensors, causing the vehicle to stutter and stall randomly at various speeds. Replacing the faulty sensor should fix the issue.

The power windows in Buick Regal models made from 1990 to 2011 can also stop working due to a faulty switch. This problem can be fixed by replacing the switch, which is less expensive than replacing the power window motor or the window regulator.

The 2011 Buick Regal has been reported to have issues with oil consumption, fouling upstream O2 sensors, electric problems, timing chains, and the braking system. The braking system has been described as terrible, and the car's engine has been known to consume oil excessively.

In summary, the Buick Regal has had some recurring problems that have affected various model years. These issues include the key getting stuck in the ignition, problems with the MAF and CPS sensors, faulty power window switches, and issues with the braking system and engine. It is important for potential buyers to be aware of these issues and to consider them when deciding whether to purchase a Buick Regal.
