The BLS was praised for its sleek design, comfortable interior, and responsive handling, but criticized for its high price and lack of a more powerful engine option.

Engine

2.0L Turbocharged Inline-4

• Turbocharger Failure: The turbocharger can fail due to excessive wear or oil starvation. Symptoms include reduced power, increased fuel consumption, and a whistling sound. The solution is to replace the turbocharger, which costs around $1,500 - $2,000+.
• Timing Chain Stretch: The timing chain can stretch over time, causing the engine to lose power and run rough. The solution is to replace the timing chain and related components, which costs around $1,000 - $1,500+.

2.8L Naturally Aspirated V6

• Intake Manifold Gasket Leak: The intake manifold gasket can fail, causing a vacuum leak. Symptoms include rough idling, reduced power, and increased fuel consumption. The solution is to replace the intake manifold gasket, which costs around $500 - $700+.

Transmission

6-Speed Automatic

• Transmission Slippage: The transmission may slip gears due to worn clutches or a faulty torque converter. Symptoms include difficulty shifting gears and loss of power. The solution is to rebuild the transmission, which costs around $2,500 - $3,500+.

Suspension

• Front Sway Bar Links: The front sway bar links can fail, causing a rattling or knocking noise and reduced handling. The solution is to replace the sway bar links, which costs around $200 - $300+ per side.
• Rear Control Arm Bushings: The rear control arm bushings can fail over time, leading to excessive tire wear and decreased handling. The solution is to replace the bushings, which costs around $500 - $700+.

Electrical
