Overview and Common Failures
Body and Interior Sedans before the restyling have weak bodywork, often rusted arches and sills are common. After the 2006 update, these cars are much more resistant to corrosion. Be sure to check the condition of the metal under all plastic overlays. The car's interior is spacious, with very rich and well-equipped trim levels. The finishing materials are good, but the wear resistance is average, as is the build quality. Electrical issues are common, but usually caused by broken wiring. Engine The 3.0-liter G6CT and 3.5-liter G6CU engines belong to the old Sigma series. Their weak points are considered to be swirl flaps, catalytic converter, and oil consumption. The 2.7-liter G6BA engine belongs to the Delta series, while the 2.7-liter G6EA belongs to the Mu series. They are slightly more reliable than their predecessors, but they have the same weak points. The 3.3-liter G6DB and 3.8-liter G6DA engines are part of the new Lambda lineup. The main complaints are related to oil consumption and short-lived timing chain drive. Transmission The 5-speed A5GF1 and A5HF1 automatic transmissions are very reliable and have a long lifespan. However, the friction material of the ATF wears out quickly from sharp starts and the hydraulic block can get clogged. The 6-speed A6LF1 and A6LF2 automatic transmissions are also known for their reliability. However, there have been issues with the bolts of the central gear coming loose. Suspension The suspension is durable and not too expensive, despite its complex design. Only adjustable shock absorbers have a low lifespan and high cost. And don't forget that sedans before and after the restyling are built on different platforms. There have been no major problems reported with the steering or brake system.
