Owners often praise the Tahoe for its versatility and ample cargo space, making it suitable for families and those needing to haul equipment. Common complaints revolve around fuel economy, particularly with the larger engines, and some reported issues with reliability as the vehicle ages.

Engine

4.8L/5.3L V8

    • Estimated Cost to Fix: $2,000 - $4,000+
    • Recalls: None Found
  • Oil Pressure Sensor Failure
    • Description/Symptoms: False low oil pressure readings, leading to incorrect dashboard warnings. This issue often stems from a faulty sensor located behind the intake manifold.
    • Solution: Replacing the oil pressure sensor.
    • Estimated Cost to Fix: $150 - $300+
    • Recalls: None Found

6.0L V8
