A recall addresses a faulty fuel suction jet pump seal that can lead to fuel leakage. This poses a fire hazard and requires prompt attention. Estimated repair cost: $300 - $700.

Airbag System Malfunction

Recalls have targeted the occupant classification sensor and its on-off switch, which can lead to the passenger airbag being deactivated. This directly impacts occupant safety. Estimated repair cost: $500 - $1500.

While not highlighted by recalls or complaints, the 2.0 TFSI engine can be susceptible to turbocharger wear over time, especially if oil changes are neglected. Estimated repair cost: $1200 - $2500.
