1984 Buick Regal problems
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 During the 1990s, while the four-door sedan superseded the two-door coupe entirely, forced-induction engines made their return, with superchargers replacing turbochargers.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.
