2011 Lexus IS F

The 2011 Lexus IS F is a high-performance sedan that distinguishes itself from the standard IS models with its powerful 5.0L V8 engine. Unlike other IS models, the IS F only came with one engine and transmission option: a naturally aspirated 5.0-liter V8 producing 416 horsepower and 371 lb-ft of torque, paired exclusively with an 8-speed automatic transmission. Owners appreciate the IS F for its engaging driving experience, strong performance, and Lexus reliability. Criticisms often include the firm ride, somewhat dated infotainment system, and relatively poor fuel economy compared to modern performance sedans.

Summary

The 2011 Lexus IS F, while a generally reliable performance sedan, does have some known issues that potential buyers should be aware of. Engine-related issues such as oil leaks and secondary air injection pump failures can be moderately expensive to address. Transmission issues like rough shifting may require relatively simple fixes like a fluid flush, or more costly solutions such as valve body repair. Owners should also be mindful of suspension wear, particularly the front lower control arm bushings, and potential electrical issues like navigation screen delamination.
