Overview

2020 Lexus GS

The 2020 Lexus GS represents a refined, rear-wheel-drive sedan with a potent V8 engine option, though this particular model features an 8-cylinder, 5.0L premium fuel powerplant. It achieves a combined EPA-estimated 19 MPG. While consumer complaints are notably absent, one critical recall concerning the fuel pump warrants attention. The vehicle's reliability is assessed as 'Good', but potential buyers should be aware of Technical Service Bulletins (TSBs) that may indicate other common wear items or minor issues. Safety ratings are not available for this model year.

Critical Failure Risk

The low-pressure fuel pump within the fuel tank can fail, leading to engine stalling. This was addressed by a manufacturer recall.

Early detection can help you avoid a $600-$1,000 repair.
