2006 Buick Allure problems
The Buick LaCrosse is a four-door, front-wheel-drive sedan manufactured by Buick since model year 2005, and marketed variously across four generations for the North American and Chinese markets.
The first-generation LaCrosse replaced the Century and Regal in North America beginning for model year 2005 as a five- or six-passenger, four-door, front-wheel-drive, V6-powered sedan using GM's mid-size W platform—and marketed in Canada as the Buick Allure. Notably, the first generation was also offered with a V8 engine, as a high-performance sub-model marketed as the LaCrosse Super (2008–2009). LaCrosse production and marketing began for China with model year 2006.
The second-generation LaCrosse was introduced for 2010 as a larger premium sedan for North American and Chinese markets using a long-wheelbase (LWB) variant of the Epsilon II platform shared with the Cadillac XTS—and available solely as a five-passenger sedan with a range of four- and six-cylinder engines.
The third generation was introduced for North America and China for model year 2017 using the GM Epsilon platform shared with the Chevrolet Impala, notably offering a mild hybrid powertrain combining 20-kilowatt (27 hp) electric and 2.5-liter Ecotec gasoline engine. North American production ended with the third generation, with model year 2019; however, it continued to be offered in China, with a 2019 facelift.
The fourth-generation LaCrosse, launched in 2023, is currently manufactured and marketed solely in China. It is powered by a turbocharged 1.5-liter or 2.0-liter four-cylinder engine.

Common 2006 Buick Allure problems
Common Problems with the Buick Allure 2006:
- Check Engine Light: The check engine light may come on for no apparent reason. This could be due to a problem with the idle air control valve or dirt in the air passages of the throttle body. Cleaning the throttle body and intake air hose with throttle body cleaner can help resolve this issue. However, if the stutter begins in higher gears, it could be due to the fourth clutch pack, which is a common problem in Buick vehicles.
- High Oil Consumption: The Buick Allure 2006 is known to have high oil consumption, especially from exhaust valve stems that do not stay in place. This issue is covered in a technical bulletin for Buick Allures between 2005 and 2008.
- Transmission Problems: The Buick Allure 2006 may experience transmission problems, especially in the lower gears. This issue is caused by the first clutch pack and seals, which are known to fail.
- Block Heater: The block heater is not a standard feature in the Buick Allure 2006. If one is installed, it has to be plugged into an outlet and does not kick in automatically. When needed, the block heater will have to be turned on to warm the engine coolant, which then circulates gently around the block through convection. This helps keep the engine warm and helps it start more easily when ambient temperature is low.
- Exterior Lighting: Exterior lighting problems are another common issue in the Buick Allure 2006. For example, the exterior lighting may not work properly or may be dim.
- Fuel System: The fuel system may have issues, such as problems with the fuel gauge system.
- Steering: Steering problems, such as difficulty steering, are also common in the Buick Allure 2006.
- Structure/Body: Structural and body issues, such as cracks in the body, are also known problems in the Buick Allure 2006.
