The sophisticated active suspension system, while providing excellent ride quality, is subject to wear over time. Components like hydraulic lines, ABC (Active Body Control) fluid, and electronic sensors can fail, leading to a rougher ride or uneven vehicle height. Estimated repair cost: $400 - $1,500+.

Mass Air Flow (MAF) Sensor Failure

The MAF sensor measures airflow into the engine. When it fails or becomes dirty, it can disrupt the air-fuel mixture, leading to performance issues. This is a common electronic component failure across many vehicles. Estimated repair cost: $200 - $500.
