1986 Pontiac Grand prix problems

pontiac logo

The Grand Prix is a line of automobiles produced by the Pontiac Division of General Motors from 1962 until 2002 as coupes and from 1989 through 2008 model years as four-door sedans.

First introduced as a full-size performance coupe for the 1962 model year, the model varied repeatedly in size, luxury, and performance during its production. The Grand Prix was the most expensive coupe Pontiac offered until the 1970s, when the Bonneville Brougham and the Firebird Trans Am became more exclusive. Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the second generation to the fifth generation for the sedan and from the second generation to the sixth generation from the coupe.

All Grand Prixs from 1962 through 1972 were pillarless hardtops (except for the 1967 convertible),

Common 1986 Pontiac Grand prix problems

The 1986 Pontiac Grand Prix, particularly the 2+2 model, is known for several common problems based on complaints from owners.

  • Nose Piece Deterioration: The composite nose piece in the front of the 1986 Grand Prix and its Monte Carlo SS counterparts can warble or become droopy over time due to exposure to the sun. This can affect the car's appearance and may require replacement or repair.
  • Engine Compartment and Undercarriage: While the engine compartment and undercarriage of the 1986 Grand Prix are generally reported to be in good condition, the actual state of these components can vary based on factors such as maintenance history and mileage.
  • Interior Issues: The interior of the 1986 Grand Prix, including the seats and steering wheel, may show signs of wear or damage over time. This can include issues with seat covers, worn steering wheel material, and other signs of aging or neglect.
  • Engine Performance: The LG4 305 V8 engine in the 1986 Grand Prix, which had a horsepower rating of 165, may require maintenance or repair over time. This can include issues with the engine's performance, reliability, or longevity.
  • Transmission Problems: Some owners of the 1986 Grand Prix have reported transmission problems, including issues with the transmission pressure control solenoid. This can cause erratic shifting or other performance issues, and may require repair or replacement.
  • Rarity and Collectibility: Due to the limited production run of the 1986 Grand Prix 2+2 model, finding replacement parts or receiving specialized service for these cars can be challenging. This can add to the cost and complexity of maintaining and repairing these vehicles.
  • Renaming Product Line: Pontiac's practice of renaming its models, such as the Grand Prix being replaced by the G6, can cause confusion for car buyers and may affect the car's perceived value or desirability.
  • Visibility: The 2004 redesign of the Grand Prix, which featured larger headlamps, a smaller grill, and coupe-like styling on a 4-door sedan, has been criticized for poor visibility and substandard interior furnishings.
  • Sales and Market Performance: The 1986 Grand Prix, particularly the 2+2 model, had relatively low sales compared to its GM cousins and competitors. This can affect the car's perceived value, desirability, and availability in the marketplace.
