However, it has also been plagued by several issues.
Engine
5.3L V8
- Intake Manifold Bolt Issue: Some vehicles may experience a loose intake manifold bolt, causing a vacuum leak. This can lead to rough idling, reduced power, and increased emissions. The fix involves tightening or replacing the loose bolt. Estimated cost to fix: $50 - $200
6.2L V8
- Valve Spring Failure: Some Suburban 1500s equipped with the 6.2L V8 may experience valve spring failure. This can cause a tapping or ticking noise from the engine, reduced power, and increased oil consumption. The solution is to replace the affected valve springs. Estimated cost to fix: $1,500 - $3,000+
Transmission
6-Speed Automatic
Delayed Shifting: Some vehicles may experience delayed or hesitant shifting. This can be caused by a faulty shift solenoid or transmission control module. Replacing the affected component can resolve the issue. Estimated cost to fix: $500 - $1,500
Transmission Slipping: In some cases, the transmission may slip or shudder during acceleration or shifting. This can indicate a worn or damaged clutch pack or torque converter. Replacing the affected component is typically necessary. Estimated cost to fix: $2,000 - $4,000+
