Overview

2015 Lexus IS

The 2015 Lexus IS presents itself as a refined compact luxury sedan, offering a potent V6 engine and Lexus's signature build quality. For the used car shopper, it represents a potentially solid value, though a closer look at its complaint history reveals areas demanding attention. While it boasts zero recalls, a significant number of owner complaints point to specific weaknesses that warrant careful consideration before purchase. The electrical system and steering are the most frequently cited areas of concern, with some reports detailing serious malfunctions. Understanding these potential pitfalls is key to a satisfying ownership experience.

Critical Failure Risk

Water intrusion into the audio amplifier, typically located in the trunk, can cause a complete loss of audio, system malfunctions, and a burning odor. This is often due to leaks from sunroof drains, window seals, or trunk lid seals.

Early detection can help you avoid a $800-$1,500 repair.
