2000 Chevrolet L30

The 2000 Chevrolet Lumina, also known as the L30 in some trims, was a mid-size sedan offering comfortable transportation and a relatively affordable price. Engine options included a 3.1L V6 producing 160 horsepower and 185 lb-ft of torque and a 3.8L V6 engine producing 200 horsepower and 225 lb-ft of torque. All Luminas came equipped with a 4T65E 4-speed automatic transmission. Owners often praised the Lumina for its spacious interior, smooth ride, and simple, easy-to-maintain mechanicals. Common complaints centered around the car’s somewhat bland styling, basic interior features, and occasionally lackluster fuel economy.

Summary

The 2000 Chevrolet Lumina, while a reliable car in its day, is now facing age-related issues. The most common problems revolve around the engine (intake manifold leaks) and transmission (shifting problems). Suspension and electrical issues are also fairly common.
